The science of aircraft seats

Here is an interesting article for all those who fly. I did not realize the effort that goes into designing an aircraft seat especially if you are seated in the first or business class.
"...In the early nineties, the best seats on airplanes were still just seats, even if they reclined almost all the way back. Then, in 1995, in first class on some long flights, British Airways introduced seats that turned into fully flat beds, and within a relatively short period airborne sleeping became a potent competitive weapon. The carriers that fly the wealthiest passengers on the longest routes have been especially aggressive about adding comforts, in both first and business (while also often shrinking the seats in economy and squeezing them closer together). A first-class passenger on the upper deck of some Lufthansa 747s gets to hop back and forth between a reclining seat and an adjacent full-length bed. On some of Singapore Airlines’ A380s, a couple travelling in first can combine two “suites” to create an enclosed private room with a double bed and sliding doors. On some flights on Emirates, first-class passengers who make a mess of the treats in their personal minibar can tidy up with a shower before they land.
The modern aircraft-seating industry is highly specialized. The number of manufacturers is small, in part because creating new seats is so complex that moving from conception to installation takes years and entails large financial risks. It also poses unique design challenges, since a premium-class seat has to create an impression of opulence in what is actually a noisy and potentially nausea-inducing metal tube filled with strangers. If you checked into a luxury hotel and were taken to a room the size of a first-class airplane cabin, and told that you’d be sharing it with eleven people you didn’t know, all of whom would be sleeping within a few feet of your own skinny bed, you wouldn’t be thrilled, especially if you were paying twenty thousand dollars for the experience. Yet it’s not unheard of for people who travel long distances in really good seats to remember the flight as one of the best parts of their trip. Making them feel that way requires a particular kind of design and engineering skill, along with what amounts, almost, to psychological sleight of hand.
In March, TheDesignAir, an air-travel Web site, published its second annual ranking of the best international business classes. The winning airline was Singapore, and the runner-up was Cathay Pacific, which is based in Hong Kong. One interesting fact about Singapore and Cathay is that they held the same positions on last year’s list, though in the other order. Another is that the business-class seats on both were created by the same design firm: James Park Associates, whose main office occupies three rooms in a building on Worship Street, in Shoreditch, in East London. Just inside the largest room is a worktable surrounded on three sides by ikea bookcases filled with fabric swatches, carpet samples, and plastic bags containing pajamas, robes, and other “soft goods” that J.P.A. created for first-class cabins on Air China. In the main part of the room, two dozen designers work shoulder-to-shoulder at computers on two long tables.
James Park, the firm’s founder and principal, is sixty-seven years old, and when he’s wearing his glasses he looks a little like the poet Philip Larkin. He earned a degree in architecture in 1974 at London’s Architectural Association, whose other alumni include Zaha Hadid, Rem Koolhaas, and Richard Rogers. His first job after graduation was with the Louis de Soissons Partnership, a distinguished architectural practice. When that firm moved out of London, he left and took what he assumed would be a stopgap job: helping to restore and design vintage railway carriages for the Venice Simplon-Orient-Express, a luxury private-train service.
“The train project became much more involving and much more enjoyable than I’d thought it would,” Park told me recently, as we sat at a big table in the firm’s conference room. “There was a lot of marquetry and very high-quality finishes in the interiors.” There was also the challenge of fitting things together in a way that would allow the wooden panels to move without splitting or cracking. “That’s a tricky problem, because a train car is moving all the time, and it isn’t a completely rigid object,” he said. “It also contracts and expands—say, as it goes up into the mountains and then comes down to Venice in the summer.”
...That train restoration led to others. Then, in the early nineteen-nineties, Singapore Airlines invited J.P.A. to compete for the job of reconceiving the first-class cabins on its Boeing 747s. “They were interested in us because of the trains, because we’d shown we were good at dealing with small spaces,” Park said. He quickly decided that aviation seating had changed little in decades, and that even in first class the ambience was coldly utilitarian. The seats were large, and they reclined, but they looked more like dentist’s chairs than like luxury furniture. “We decided to try to do something about the way the elements were put together and presented, to make them more comfortable, and to provide more of a club atmosphere,” he said.
The interiors that Park created for the Orient-Express trains resemble rolling versions of Downton Abbey, but achieving that effect while satisfying late-twentieth-century safety regulations required lots of modern technology. All of Park’s “loose-fit” woodwork had to be anchored securely enough to remain intact after a train wreck, and it had to be impregnated with a flame-retardant chemical and finished not with ordinary varnishes or paints but with what are known as “intumescent” coatings, which foam up when they’re exposed to high heat, forming an insulating layer that prevents the underlying wood from igniting.
Airplane interiors are even more tightly regulated. Nearly every element undergoes a safety-enhancing process called “delethalization”: seats have to withstand an impact equal to sixteen times the force of gravity, and to remain in place when they do, so that they don’t block exit routes or crush anyone, and they can’t burst into flames or release toxic gases when they get hot. Doing something as simple as slightly increasing the thickness of the padding in a seat cushion can necessitate a new round of testing and certification, because a more resilient seat could make a passenger bounce farther after an impact, increasing the risk of injury caused by turbulence or a hard landing. Delethalizing some premium-class seats—in which a passenger’s head and torso have a lot of room to accelerate before being stopped by something solid—requires the addition of a feature that many passengers don’t even realize is there: an air bag concealed in the seat belt.
In economy, the tight spacing of the seats makes air bags mostly unnecessary. But seat-back video screens and the hard frames that surround them pose a safety challenge, partly because of the potential for injuries caused by head strikes, and partly because the computers and the electrical systems that serve them have to be both fireproof and fully isolated from the plane’s—so that crossed wires in somebody’s seat don’t allow a ten-year-old playing a video game to suddenly take control of the cockpit. Largely as a result, in-flight entertainment systems are almost unbelievably expensive. The rule of thumb, I was told, is “a thousand dollars an inch”—meaning that the small screen in the back of each economy seat can cost an airline ten thousand dollars, plus a few thousand for its handheld controller.
At the same time, nearly every surface on an airline seat has to be easily replaceable during the brief interval between landing and takeoff, so that if a passenger spills a glass of red wine the seat won’t have to be kept vacant for the following flight: a lost fare. No design change is made casually, because even small ones can affect operating costs. Gulf Air, which is based in Bahrain, reduced its annual fuel bill by a hundred and twenty thousand dollars a few years ago by using slightly thinner leather in the upholstery of its first-class seats—a change that involved just sixteen seats on fifteen planes.
Despite such challenges, J.P.A. created a first-class cabin for Singapore that was seductively different from anyone else’s. The seats, which could be transformed into fully flat beds, looked less like conventional airplane seats than like oversized wing chairs, each with its own ottoman, dining table, and wood-framed video monitor. (The “wood” was actually a delethalized photographic imitation.) The new seats first flew in 1998. They won many awards and remained in service in their original form for almost a decade. Their successors fly today.
The Singapore job enhanced J.P.A.’s reputation, and not just in aviation. The firm created a first-class lounge for Singapore Airlines at Changi Airport, and soon afterward it won contracts for several hotel renovations, including, in 2009, a hundred-million-dollar redesign of the guest rooms in the Pierre, in New York. (Most of J.P.A.’s hotel work is handled by a second office, in Singapore.) As a result, the firm’s portfolio grew to include luxury environments on a variety of scales, and Park’s conception of what J.P.A. does inside aircraft extended from the plane to the airport and beyond. “There are certain little events you experience as you progress through this promenade up to the plane,” he told me. “They should climax in your vision of the seat.”
..... Nearly every hard surface was a curve, and the colors were soothing: tan, mauve, plum, taupe, coppery-pinkish, brown. The plane had two business-class sections: a small one, with just eight seats, directly behind first class, and a larger one behind that, with thirty-four seats. To keep the larger section from seeming enormous (and therefore less exclusive), J.P.A. had used different upholstery tones in alternate seats, checkerboard style—a pattern that causes the brain to register less than the entire expanse. “In a way, it’s a trick of the eye,” Tighe said. “It cuts down on the perception of the repetition of objects.”
Tighe pushed a button on a control panel near my arm, and hidden downlights subtly accentuated the detailing in the console on my right. A button on the inner surface of the aisle-side armrest, he showed me, was positioned so that a Singapore Girl could switch off my video screen once I’d fallen asleep. He extended the tabletop, and said that a Singapore Girl could do that from the aisle, too, without reaching across my lap, and then he raised it into the proper position for breakfast in bed. He clicked open a door to the right of the video console, revealing a lighted makeup mirror—useful upon arrival. “A good seat doesn’t show you everything it’s got in the first ten minutes,” he said. “It surprises you during the flight, and lets you discover things you weren’t expecting.” Such features can pay off in unexpected ways: passengers who like their seats tend to give higher ratings to everything on their flight, including movie selections that haven’t changed.
To the left of the video screen was a retractable coat hook—a surprisingly humble accessory, given that long-haul first-class seats nowadays often have a shallow personal “closet,” in which passengers can hang things like jackets and sweaters. But Tighe explained that the simplicity was intentional. Singapore had stipulated that nothing J.P.A. did should undermine the airline’s emphasis on personal service, and the hook, he said, creates an opportunity for passenger interaction. “You might hang your jacket on it when you arrive at your seat, but by the time you’ve sat down a flight attendant will have taken it away.” Similarly, J.P.A. designed the seat so that its transformation into a bed is mainly a manual operation, rather than, as is common, something a passenger can do by pushing buttons. “Usually, a flight attendant will make your bed up for you, maybe while you’re getting ready to go to sleep,” he said. The upper part of the bed is created by pulling down the seat back, revealing a flat, fabric-covered mattress section attached to the other side. (Leather is nice for sitting and is easy to clean quickly, but it can be hot and slippery for sleeping.) A cantilevered panel fills the gap between that surface and the stationary footrest, and then a Singapore Girl adds bedding and a pillow. Manual operation has the additional benefit of reducing the seat’s weight, by shrinking the machinery inside it.
Next Generation, as the name suggests, evolved from an earlier seat that J.P.A. designed for Singapore. In both, the passenger sits facing forward but sleeps on the diagonal, an innovation that makes it possible to create what looks like a first-class experience in a significantly smaller space. In bed mode, each seating unit borrows some empty volume from the underside of the shell of the seat in front of it. Designing seats is like solving a three-dimensional puzzle, in which all the pieces have to fit together and even tiny spaces can be significant. During one project, on which J.P.A. worked essentially around the clock, by using employees in both of its offices, the designers in Singapore sent the designers in London an exultant overnight message saying that they thought they’d found another half inch.
Beds on aircraft aren’t a recent invention. Some of Pan Am’s early planes had Pullman-style berths, and on one of those planes, in 1937, a crew member woke a man and asked to look out his window, so that he could complete his celestial navigation chart, because he hadn’t been able to see the North Star clearly from the cockpit. The awakened passenger recalled later that the actress Anna May Wong, who had starred in the film “Shanghai Express” five years earlier, was in the berth across the aisle, and that he knew she was asleep, on the other side of her curtain, because he could hear “a kind of soft snore.” As air travel extended down the income scale, though, and as airplanes got faster, bedlike sleeping surfaces became less common, then disappeared, until British Airways reintroduced them, in the nineties.
Early flights were classless in the sense that only the wealthy could afford them. (In 1938, a ticket on Imperial’s flight from London to Durban, which took six days, cost a hundred and twenty-five pounds, hotels and meals included—a little less than a quarter of the cost of an average house.) On early mixed-class planes, the first-class seats were sometimes back near the tail, farther from the noise of the engines and, perhaps, from the chauffeur-like men handling the controls. In 1977, British Airways introduced a third division, a mid-plane Executive Cabin, which it described as having “a quiet, exclusive atmosphere free from the distraction of movies and young babies.” The seats and their spacing were the same as those in economy, but the section was intended for passengers paying nondiscounted fares—typically, business travellers.
The first true business class arose soon afterward, and versions of it have evolved, since then, in response to the fluctuations of national economies, the increased competition that followed airline deregulation, and other factors. One key to its success is that many of the tickets are purchased with the world’s oldest virtual currency: Other People’s Money. For self-paying passengers who upgrade with frequent-flier miles, the cost is supported by things like the fees that retailers pay to credit-card companies, which buy miles in bulk from airlines and distribute them to cardholders as rewards; for corporate executives and their lawyers, bankers, and consultants, the expense is partly borne by shareholders, as is also the case with corporate jets. (Private jets divide the wealthy into two classes: there are the rich, who fly first class without thinking about it, and then there are the jet-rich, who have never seen the inside of Concourse B.)
Not long after beds returned to first class, they began to appear in business class, too. Today, the variation in detail, size, spacing, comfort, and ticket price in all classes is so great that traditional cabin designations aren’t very meaningful. Ben Orson, the managing director of J.P.A.’s London office, told me that it’s probably more accurate to think of seating types as tightly spaced points on a continuum—from the thrombosis-inducing perches on regional jets to the bedroom-like micro-palaces on Emirates and Etihad. Between those extremes is a Cambrian explosion of features and variants, including an emerging intermediate class with names like Economy Comfort, Economy Plus, and Main Cabin Extra. Air New Zealand has been especially innovative, and in recent years has introduced two distinctive seat types: the Skycouch, which is formed by turning three adjacent economy seats into a broad mini-bed, and the Spaceseat, which the company classifies as “premium economy” but on some airlines might pass for business class.
Competing for travellers in this way is economically risky. Some first-class cabins on Kingfisher Airlines, based in India, had a bar, a bartender, and a spacious lounging area, as well as a chef who prepared delicacies to order. But Kingfisher stopped flying in 2012, after just seven years in operation, in part because it had allocated too much cabin space to functions that delighted passengers but produced no revenue.
Yet moderation is risky, too. Premium cabins contribute disproportionately to an airline’s economic performance—both directly, through higher ticket prices, and indirectly, by solidifying relationships with big-budget customers who fly all the time. Business class is especially valuable; first class can be problematic, because first-class ticket holders require extra pampering and won’t tolerate overbooking. Web sites like SeatGuru enable picky fliers to compare seats on many routes, and keeping such fliers loyal is expensive: new first-class seating units can cost more than half a million dollars each. Jami Counter, a senior director at TripAdvisor, which owns SeatGuru, told me, “The true international first-class cabin actually keeps shrinking, because the international business-class cabin has become such a great product, to the point where you’re differentiating more on things like food and service.”
Because costs are high, passenger density is extremely important, especially outside first class. The critical industry measure is “pitch,” which is the distance between a point on one seat and the same point on the seat just ahead of it or just behind it. Short pitches mean more rows; more rows mean more revenue (and, usually, cheaper tickets—the main criterion by which most economy passengers compare flights). Seat pitch on commercial jets ranges from about thirty inches, in many short-haul economy cabins, to slightly more than ninety inches, in a few long-haul first-class cabins. In any cabin with more than a few rows, even centimetres become important, because they add up. If you have a seating pattern that repeats every seventy inches, sixty inches of leftover space is an expensive extravagance, because the difference between profit and loss on a given flight can be less than the fare from a single seat. Accurately pricing tickets for all cabins has become so important that airlines work hard to predict demand, which is influenced, on an hourly basis, by weather, military coups, school vacations, disease outbreaks, sporting events, and innumerable other factors. Prices move constantly, as conditions change. “If you sell out a flight too quick,” Tighe told me, “you weren’t charging enough.”
During my visit to J.P.A., nearly everyone in the office was preparing for the Aircraft Interiors Expo, which is held each spring in Hamburg and is the world’s largest trade show for people who design, manufacture, sell, or buy almost anything that goes into the inside of almost anything that flies. The J.P.A. designers were working on a new long-haul business-class seat, which they were developing in partnership with an aircraft-interiors manufacturer called Jamco.
The seat—its prototype was first shown at Hamburg in 2013—is in some ways a descendant of a fully-flat-bed seat that J.P.A. and another manufacturer introduced in 2007. Versions of that earlier seat, called Cirrus, are used by a number of airlines, mostly in business but sometimes in first. Cirrus seats are enclosed within curving, podlike shells—a look familiar to many international travellers, who, by now, have either flown in Cirrus seats or grumpily walked past them on the way to the back of the plane. The seats nest together in a herringbone pattern, so that each unit is oriented diagonally to the longitudinal axis of the plane, like cars parked at an angle to a curb. That arrangement makes it possible to provide more than six feet of sleeping surface within a pitch of less than four feet, while also preserving what may be the single most coveted modern premium-class feature: direct aisle access from every seat, so that passengers never have to say “Excuse me” when they get up to go to the bathroom. The Cirrus arrangement is called “reverse” herringbone, because it flips the orientation used by Virgin Atlantic, which was the first airline to angle business-class passengers for both sleeping and sitting. In Virgin’s arrangement, passengers at the sides of the cabin sit with their back to the window and their feet toward the aisle; in Cirrus’s, they face the other way.
“The Virgin seat was very innovative, but we felt it was a shame to make people look away from the window,” Tighe told me. “And that seat has a global limitation, because there are cultures in which the soles of the feet are considered unsavory, or rude, and people are uncomfortable sleeping with their feet exposed where other people are walking—mainly in Asia and the Middle East.” Cultural differences in air travel can be significant. Americans are less bothered than Arab sheikhs when slobs wearing flip-flops end up in first class.
J.P.A.’s new seat, like Cirrus, will be sold, in various versions, to more than one airline, and the purpose of demonstrating it in Hamburg and elsewhere is to line up customers in advance of production. The prototype is a full-size mockup of a five-unit cluster, in which one seat is fully functional, another is set up as a bed, and a third is partially reclined. “The C.E.O. of the airline usually sits in the seat that works, and everyone else gathers around,” Orson told me. During demonstrations, J.P.A.’s designers act as salespeople, but they also watch closely for hints about likely passenger behavior. One thing they learned from watching airline executives at last year’s show was that a curved element on the aisle side of the seat shell, near a seated passenger’s shoulder, occasionally bumped a passenger who was getting up, so they eliminated it.
After the 2013 expo, the model was shipped to Seattle, Singapore, Tokyo, and other cities, for additional demonstrations, and by the end of last year representatives from several dozen airlines had studied it. Even so, the seat is at least two years from launch, and almost everything about it, including its name, is still a trade secret. Before this year’s expo, the model was disassembled, repaired, modified, rebuilt, and refinished in a different color scheme, and while that work was under way J.P.A.’s designers built a crude mockup out of white foam-core panels. The seats themselves were ordinary office chairs, but the mockup allowed the designers to double-check things like sight lines and clearances.
Full-size models have been important tools for aircraft designers for a long time. Computer software can create extraordinarily realistic three-dimensional representations of entire airplane cabins, Park told me, but there are still features and qualities you can’t perceive accurately without studying a full-size physical object. The demonstration model of J.P.A. and Jamco’s new business-class seat was built in Pitstone, about forty miles north of London, by Curvature Group, a private company, which makes exquisitely detailed 1:1 scale models of everything from cell phones to rockets. Tighe lives nearby, and sometimes looks in on his way to or from work. One day, I joined him there, and James Lilley, who is Curvature’s project manager, gave us a tour. In one room, we watched a man gluing together several huge polyurethane planks that he would later turn into part of a boat model, using the largest of Curvature’s thirteen computer-controlled milling machines. “We can quite comfortably build a full-size train in-house,” Lilley said. Curvature built a (non-functioning) prototype railway car for Hitachi not long ago, Tighe said, and the model had such a perfectly detailed interior that even when you walked inside it you couldn’t tell it wasn’t the real thing.
In another room, a craftsman who had been hand-shaping the curved edge of part of a seat shell explained to Tighe why reproducing a particular color sample would be difficult. The sample, a translucent blue, had been sent over by a J.P.A. materials designer, who thought that it might be perfect for a particular trim piece on the new seat. “We think we know how to achieve this,” the craftsman said, “but what you’d have to do is a real pain in the ass.” Creating the sample’s effect in a coating, he said, would require a primer, a black coat, a gloss coat, a paint coat, a lacquer coat, and at least a couple of other things, plus long drying times between steps. But he thought he’d found a simpler way to achieve almost the same thing, and he gave Tighe two samples. “The first person who figures out how to make a convincing chrome paint will make a fortune,” Lilley said.
Building a model of an airplane seat can take Curvature as long as ten weeks, because virtually every part has to be custom-made. Once a prototype is finished, building an actual airplane seat is faster, but the process is similar. “The aviation-seating industry isn’t like the automotive industry,” Park told me later. “The multiples are much, much smaller, and it’s still almost an artisan process. With motorcars, robots do most of the welding and, nowadays, even a lot of the electrical work. With aviation seats, even parts of the frames are milled by hand.” Tighe added, “Once you know what goes into an airplane, it seems insane that you can buy an airplane ticket for as little as you can.”
... Even on flights on which economy was half empty, first was always full, and business was oversubscribed. I resigned myself to my thirty-one-inch pitch, and, once the plane was in the air, sought comfort in the thought that my seat’s entertainment system had cost more, by several thousand dollars, than all the video and audio equipment in my house.

Muslim population in a country and its state of violence

I hold no brief for this thesis but it is nevertheless interesting and thought provoking:

Dr Peter Hammond’s book, Slavery, Terrorism and Islam: The Historical Roots and Contemporary Threat: has an interesting- and perhaps a questionable- thesis on the population of Muslims in a country and agitation and riots..

According to Dr Hammond,  islamization begins when there are sufficient Muslims in a country to agitate for their religious privileges. When politically correct, tolerant, and culturally diverse societies agree to Muslim demands for their religious privileges, some of the other components tend to creep in as well. In the following table, the yardstick defined by Dr Hammond has been applied to Muslim population.

 As long as the Muslim population remains around 1% of any given country they will be regarded as a peace-loving minority and not as a threat to anyone. In fact, they may be featured in articles and films, stereotyped for their colorful uniqueness: (The lowest population of Muslims in any district is 3.5% in India.)

US 1.0
Australia 1.5
Canada 1.9
China 1 – 2
Italy 1.5
Norway 1.8

At 2% and 3% they will begin to proselytize from other ethnic minorities and disaffected groups with major recruiting from jails and among street gangs:

Denmark 2.0
Germany 3.7
United Kingdom 2.7
Spain 4.0
Thailand 4.6

From 5% on they will exercise an inordinate influence in proportion to their percentage of the population. They will push for the introduction of halal (clean by Islamic standards) food, thereby securing food preparation jobs for Muslims. They will increase pressure on supermarket chains to feature it on their shelves — along with threats for failure to comply. (United States). At this point, they will work to get the ruling government to allow them to rule themselves under Sharia, the Islamic Law. The ultimate goal of Islam is not to convert the world but to establish Sharia law over the entire world.

France 8.0
Philippines 5.0
Sweden 5.0
Switzerland 4.3
Netherlands 5.5
Trinidad &Tobago 5.8

When Muslims reach 10% of the population, they will increase lawlessness as a means of complaint about their conditions (Paris, car burnings). Any non-Muslim action that offends Islam will result in uprisings and threats (Amsterdam – Mohammed cartoons).

Guyana 10.0
India 13.4
Israel 16.0
Kenya 10.0
Russia 10-15

After reaching 20% expect hair-trigger rioting, jihad militia formations, sporadic killings and church and synagogue burning:

Ethiopia 32.8
Chad 53.1
Lebanon 59.7

From 60% you may expect unfettered persecution of non-believers and other religions, sporadic ethnic cleansing (genocide), use of Sharia Law as a weapon and Jizya, the tax placed on infidels:

Albania 70.0
Malaysia 60.4
Qatar 77.5
Sudan 70.0

After 80% expect State run ethnic cleansing and genocide:

Bangladesh 83.0
Egypt 90.0
Gaza 98.7
Indonesia 86.1
Iran 98.0
Iraq 97.0
Jordan 92.0
Morocco 98.7
Pakistan 97.0
Palestine 99.0
Syria 90.0
Tajikistan 90.0
Turkey 99.8
UAE 96.0

 100% will usher in the peace of ‘Dar-es-Salaam’ – the Islamic House of Peace – there’s supposed to be peace because everybody is a Muslim:

Afghanistan 100
Saudi Arabia 100
Somalia 100
Yemen 99.9

To satisfy their blood lust, Muslims then start killing each other for a variety of reasons.

The percentages source of Muslim population used by Dr Peter Hammonds is CIA’s The World Fact Book, 2007 and for Indian Muslim Population, the census data of Govt of India of 2001 is used. 

Why we love numbers?

We cannot help but react to numbers, but why are odds masculine and evens feminine? Why were Levi's 501s and WD-40 given those names? And is number 3 really 'warm' and 'friendly'? Why is number 13 considered unlucky? Why is 7 such a lucky charm? 

The earliest words and symbols used for numbers date from about 5,000 years ago in Sumer, a region in what is now Iraq. The Sumerians did not look far when coming up with names. The word for one, ges, also meant man, or erect phallus. The word for two, min, also meant woman, symbolic of the male being primary and the woman his complement, or perhaps describing a penis and a pair of breasts.

Initially, numbers served a practical purpose, such as counting sheep and calculating taxes. Yet they also revealed abstract patterns, which made them objects of contemplation. Perhaps the earliest mathematical discovery was that numbers come in two types: even – those that can be halved cleanly, such as 2, 4 and 6 – and odd – those that cannot, such as 1, 3 and 5. Pythagoras, who lived in the sixth century BC, echoed the Sumerian association of one with man and two with woman by proclaiming odd numbers masculine and even numbers feminine. Resistance to splitting in two, he argued, embodied strength, while susceptibility to splitting in two was a weakness. He gave a further arithmetical justification: odd was master over even, just as man is master over woman, because when you add an odd number to an even number, the answer remains odd.

Pythagoras is most famous for his theorem about triangles, but his belief about number gender has dominated western thought for more than 2,000 years. Christianity embraced it within its creation myth: God created Adam first and Eve second. One signifies unity, and two is the "sin which deviates from the First Good". For the medieval church, odd numbers were stronger, better, more godly and luckier than even, and by Shakespeare's time, metaphysical beliefs about odd numbers were common: "They say there is divinity in odd numbers, either in nativity, chance or death," Falstaff declares in The Merry Wives of Windsor. These superstitions remain. Mystical numbers still tend to be odd, notably the "magic" three, the "lucky" seven and the "unlucky" 13.

It is human nature to be sensitive to numerical patterns. These patterns provoke subjective responses, sometimes extreme ones but also more generally, leading to deeply held cultural associations. 
Culture, language and psychology play a role in the way we understand mathematical patterns; numbers have a fixed mathematical meaning – they are abstract entities signifying quantity and order – yet they also tell other stories. The influential German theologian Hugh of Saint Victor (1096–1141) provided an early guide to numbers: 10 represents "rectitude in faith", nine, coming before 10, "defect among perfection", and 11, coming afterwards, "transgression outside of measure".

In modern times the number 11, for example, is an essential element of KFC's corporate mythology: its signature dish is fried chicken seasoned with Colonel Sanders's secret original recipe of 11 herbs and spices. "This is the key mystical use of the number 11 in commercial culture," says Greg. The number represents transgression, he adds, in this case an extra ingredient, one beyond the ordinary. "Eleven has just gone that one past 10. It has recognised that there is an order to things, and now it is exploring the distance beyond. Eleven is opening the door to the infinite, but it's not going too far. It is … rebellion at its most finite." I ask if Colonel Sanders was therefore no different from the rocker in Spinal Tapwhose amp went up to 11 so it could be louder than amps labelled to 10. Greg laughs: "Yes! But I actually believe it. I believe that 11 is more interesting than 10."

The Spinal Tap-style extra 1 is a common meme. A classic example is Levi's 501 jeans. "This raises the expectation but doesn't overplay it. It's that extra little bit, and that is what Levi's is always doing, or in its glory days always did: adding an extra little button here or a new piece of sewing there. And it works well with the big decimals: the film 2001: A Space Odyssey, the 101 drum machine, Room 101. It wasn't Room 100 – who'd be scared of that?"

The significance of the extra 1 is an established part of Indian culture.Shagun is the custom of giving a round sum of money as a gift, with one rupee added. Gift envelopes in wedding shops, for example, come with a one rupee coin glued to them, so you don't forget it. While there is no single explanation for the practice – some say the one is a blessing, others that it represents the beginning of a new cycle – it is accepted that the symbolic value of the extra one is as important as the monetary value of the notes inside.

In business, as in religion, a good number is fundamental. The number 10 – "rectitude in faith" – strengthens faith in the anti‑acne cream Oxy 10: "Ten is about balance, security, returning to the norm. It's the absolute decimal," says Greg. "There is no argument with 10." I asked him if he thought the all-purpose lubricant WD-40 would have been as successful if it had been called WD-41. "WD-41 would not be reliable," he insisted. "WD-41 would have more stuff in it than you would want. WD-40 is not over-claiming. It is a simple, humble enhancement." Academic research corroborates this semiotic evaluation: for household products, divisible numbers are more attractive to consumers than indivisible ones. 

In 2011, Dan King of the National University of Singapore and Chris Janiszewski of the University of Florida demonstrated that an imaginary brand of anti-dandruff shampoo was better liked when it was called Zinc 24 than when it was called Zinc 31. The respondents preferred Zinc 24 so much that they were willing to pay 10% more for it. King and Janiszewski argued that customers prefer 24 because they are more familiar with the number from their schooldays, when the lines 3 x 8 = 24 and 4 x 6 = 24 were drummed into them by rote. By comparison, 31 is a prime number and does not appear in any school multiplication table. 

To reinforce their hypothesis that processing fluency increases brand preference, King and Janiszewski designed a follow-up experiment that subtly included a multiplication sum in the advertisement for a numbered brand. When there was no tag line, the participants preferred Solus 36 over Solus 37, as would be expected. But when the researchers included the tag line, Solus 36 increased in popularity and Solus 37 became even less popular. King and Janiszewski argued that our familiarity with 6, 6 and 36, from the six times table sum 6 x 6 = 36, increases our fluency in processing the numbers, just as the unfamiliarity of 6, 6 and 37, which are not arithmetically related, decreases it. The pleasure rush that comes from subconsciously recognising a simple multiplication makes us feel good, they said, and we misattribute the buzz as satisfaction with the product. We are always sensitive to whether a number is divisible or not, and this sensitivity influences our behaviour.

Another response to numbers is affection. More than 30,000 people took part in the first few weeks of testing. Here is an idea of the words they used. Number one: independent, strong, honest, brave, straightforward, pioneering, lonely. Two: cautious, wise, pretty, fragile, open, sympathetic, quiet, clean, flexible. Three: dynamic, warm, friendly, extrovert, opulent, soft, relaxed, pretentious. Four: laid-back, rogue, solid, reliable, versatile, down-to-earth, personable. Five: balanced, central, cute, fat, dominant but not too much so, happy. Six: upbeat, sexy, supple, soft, strong, brave, genuine, courageous, humble. Seven: magical, unalterable, intelligent, awkward, overconfident, masculine.

King and Janiszewski conducted an experiment in which the participants indicated whether they liked, disliked or felt neutral about every number from 1 to 100. The results showed that our liking of numbers follows clear patterns. Most striking, however, was the unpopularity of numbers ending in 1, 3, 7 and 9. The primes are significant features of our internal landscape of numbers for the rest of us. 

Our brains are always switched on to arithmetic.


Everything you always wanted to know about ants...




We have always wondered about the organization of ants - how they form a line and how they are able to survive. Here is a detailed, fascinating scientific research that sheds light on their behaviour. Next time you go on a picnic and curse the ants making a beeline for your food, remember this article by Emily Sanger....


Give a colony of garden ants a week and a pile of dirt, and they’ll transform it into an underground edifice about the height of a skyscraper in an ant-scaled city. Without a blueprint or a leader, thousands of insects moving specks of dirt create a complex, spongelike structure with parallel levels connected by a network of tunnels. Some ant species even build living structures out of their bodies: Army ants and fire ants in Central and South America assemble themselves into bridges that smooth their path on foraging expeditions, and certain types of fire ants cluster into makeshift rafts to escape floods.

How do insects with tiny brains engineer such impressive structures?

Scientists have been studying the social behavior of ants and other insects for decades, searching for chemical cues and other signals that the insects use to coordinate behavior. Much of this work has focused on understanding how ants decide where to forage or build their homes. But new research combining observations of ant behavior with modern imaging techniques and computational modeling is beginning to reveal the secrets of ant construction. It turns out that ants perform these complex tasks by obeying a few simple rules.

“People are finally starting to crack the problem of producing these structures, which are either made out of soil or the ants themselves,” said Stephen Pratt, a biologist at Arizona State University. The organization of insect societies is a marquee example of a complex decentralized system that arises from the interactions of many individuals, he said.
Cracking these problems could lead to improvements in swarm robotics, large numbers of simple robots working together, as well as self-healing materials and other systems capable of organizing and fixing themselves. More broadly, identifying the rules that ants obey could help scientists understand how biologically complex systems emerge — for example, how groups of cells give rise to organs.
“Self-organizing mechanisms are present everywhere in nature, from the development of an embryo to the organization of large animal populations,” said Simon Garnier, a biologist at the New Jersey Institute of Technology.
Guy Theraulaz, a behavioral biologist at the Research Center on Animal Cognition in Toulouse, France, and collaborators have been studying insect nests for the last 20 years, building more complex and realistic models as their data improved. They have discovered that three basic guidelines governing when and where ants pick up and drop off their building materials are sufficient to create sophisticated, multilayered structures.
“It all results from local interactions between the individuals,” said Garnier, a former student of Theraulaz’s who now studies living ant bridges. “The final structure emerges without central coordination.”
Theraulaz’s team painstakingly analyzed videos of ants crawling across petri dishes as they attempted to build a shelter, noting each time that an ant picked up or dropped off a grain of sand. The researchers discovered three main rules: The ants picked up grains at a constant rate, approximately 2 grains per minute; they preferred to drop them near other grains, forming a pillar; and they tended to choose grains previously handled by other ants, probably because of marking by a chemical pheromone.
The researchers used these three rules to build a computer model that mimicked the nest-building behavior. In the model, virtual ants moved randomly around a three dimensional space, picking up pieces of virtual sand soaked in a virtual pheromone. The model ants created pillars that looked just like those made by their biological counterparts. The researchers could alter the pillars’ layout by changing how quickly the pheromone evaporates, which could explain why different environmental conditions, such as heat and humidity, influence the structure of ant nests. (They published a preliminary version of the model in a conference report in 2011 but haven’t yet published the more refined version, which better mimics real ants.)
“The real novelty here is our newly acquired ability to observe in detail the formation and the transformations of these structures,” Theraulaz said. “We finally have access to precise data on how living things get together to form complex yet fully functional and reactive structures.”
After a weeklong simulation, the virtual ants created something that looked like a real nest; layers stacked together with connections between them. The connections themselves were not explicitly written into the rules, Theraulaz said.
“For the longest time, people never would have believed this is possible,” said Chris Adami, a physicist and computational biologist at Michigan State University, who was not involved in the study. “When looking at complex animal behavior, people assumed they must be smart animals.”
For David Hu and collaborators at the Georgia Institute of Technology, researching ant architecture is both a livelihood and a workplace headache. Hu’s team studies living architecture in which “ants are the bricks and the brick layers,” Hu said. But the fire ants in Hu’s lab are also adroit escape artists. They build towers to escape their enclosures and creep under locked doors. Hu is terrified of three-day weekends, which give the ants more time to break free and build bivouacs — nests made of hundreds of thousands of ants — under his colleagues’ desks. When everyone returns to work, he receives panicked calls from infested offices.
“We have ants escaping from our lab all the time,” Hu said. “The bivouacs are sophisticated, with tunnels and windows that can open and close in response to humidity and temperature.”
In his research, Hu is focused on first understanding a simpler structure — ant rafts. The insects can escape floods in their habitat by assembling into rafts made up of up to 100,000 members. The surprisingly buoyant structures, which can be as large as a dinner plate, can float for weeks, enabling the colony to survive and find a new home.
Hu and collaborators had previously shown that after a spoonful of ants is dropped into water, the blob of insects transforms into a pancakelike raft through a simple process: each ant walks randomly on the surface of the blob until it hits the water’s edge. “An individual ant can’t know how big the raft is, where it is in the raft and what other ants are doing,” Hu said. “The only communication goes on at the edge of the structure — that’s where the structure grows.” Hu’s team used these simple rules to build a virtual ant raft that had the same dynamics as one made by real ants.
Wanting to understand exactly what gives the ant rafts their remarkable strength and buoyancy, Hu’s team peeked inside the structure. They froze rafts of ants and then created images of them using computed tomography (also known as CT scans).
The findings, which will be published in an upcoming paper in the Journal of Experimental Biology, reveal that ants weave themselves into something like three-dimensional Gore-Tex, a fabric that is both breathable and waterproof. The ants form air pockets by pushing away from whichever ants they are connected to, creating highly buoyant rafts that are 75 percent air. The weave of the ant fabric is held together by multiple connections among individual ants, which orient themselves perpendicular to one another. “What’s happening at the big scale is the result of lots of interactions at the small scale,” Hu said. The result is a water-repellant lattice that enables even the ants at the bottom of the structure to survive.
As an engineer, Hu views ant conglomerates like any other material, studying their properties much as one might study plastic, steel or honey. Ants, however, have the unusual ability to act as either a liquid or a solid, and Hu hopes further research into this ability will help engineers design self-healing structures such as bridges capable of sensing and mending cracks.
To find his ant architects, Garnier sometimes spends days with his collaborators wandering the rainforest on an island in the Panama Canal. But once in close range, the target is easy to spot: Huge swaths of army ants in search of food for their voracious young sometimes cover the length and almost half the width of a football field. Ants from this nomadic species, named for their characteristic marching columns, blanket their surroundings. To expedite their relentless foraging, the ants rapidly build bridges over gaps in their path or across trees, using their own bodies as building blocks to create a smooth and expedient path for their kin. Scientists have long studied these curious creatures, exploring the evolutionary advantages of their foraging and bridge-building tactics, but Garnier and collaborators are among the first to study exactly how the structures form. They build obstacles in the path of the marching column and record the ants as they build a bridge.
Like fire ant rafts, bridges are built based on simple rules and possess surprising strength and flexibility. As soon as an ant senses a gap in the road, it starts to build a bridge, which can reach a span of tens of centimeters and involve hundreds of ants. Once the structure is formed, the ants will maintain their position as long as they feel traffic overhead, dismantling the bridge as soon as the traffic lightens. “The exact timing of their decision to join or leave the structure maximizes stability as a function of traffic on the trail,” Garnier said. “The rules of behavior in forming and dismantling the bridge are optimally designed to handle the traffic.”
Garnier’s team is now studying how individual ants cling to one another to create the structure and how ants at the fastening points can hold the weight of 100 comrades. “I think this is a new, very exciting approach,” said Bert Hölldobler, an evolutionary biologist at Arizona State University who has been studying ants for more than 40 years.
One of the most exciting findings to emerge from studies of living architecture “is how dynamic and rich this process is,” said Scott Turner, a biologist at the State University of New York College of Environmental Science and Forestry in Syracuse. Garnier’s work shows that ants build and disassemble bridges according to changing needs. Preliminary work from Hu’s group, which also studies bridges, shows that the structure’s properties, such as strength and integrity, evolve with changing conditions.
Although Hölldobler is excited about all three projects, he cautions that just because a model mimics real ant behavior doesn’t mean it reflects what’s actually happening. He cites the case of a model of desert ants that re-created their complex foraging expeditions without the need for a chemical trail marker, created at a time when scientists had found no evidence for one. But Hölldobler’s team later discovered that the insects do indeed use chemical markers, limiting the usefulness of the model.
Also currently missing is an evolutionary approach to understanding the ant behavior. “If we can understand how rules emerge from other rules and how they change with the environment, that would be extraordinarily fruitful,” said Adami, who is planning to work with Garnier on this question.
Ant Traffic
Garnier said he was inspired to examine ant behavior after studying human pedestrian traffic. “It’s a fascinating question to understand how individuals that are less cognitively able than we are can collectively achieve results that are sometimes better than what we can do with our big brains,” he said. Ants on a foraging mission are typically carrying loads two to three times their size and running at a human equivalent of 60 miles per hour. The insects avoid traffic jams by spontaneously forming three lanes of traffic, a center lane of homeward bound ants flanked by two lanes of insects heading out on the hunt. It’s unlikely that swarms of speeding humans could organize themselves so effortlessly, Garnier said. “If you removed traffic lanes in New Jersey, it would be a nightmare,” he said.
Meanwhile, engineers are already dreaming up useful applications. They hope to use ant construction principles to design modular robots that can self-organize. Adami imagines a swarm of robots sent to Mars to build a structure from Martian soil ahead of the arrival of humans. The beauty of a decentralized system is that a project can succeed even if individual parts fail.
Dynamic ant architecture might also provide insight into how to make buildings more adaptive, changing its properties based on how many people are inside, for example. To make a living building, “you need to continually monitor the environment and what effect the swarm has on the environment,” Turner said.
Ants might even shed light on the complex organization of the organ we use to study them — the brain. The behavior of an ant community resembles the organization of neurons into a functioning brain, Hölldobler said. “Each neuron is relatively dumb, but if you take billions of neurons, they interact in a way that we have only scratched the surface of understanding.”

Two books on Failure



Books about failure put both their authors and their readers in awkward positions. Writers are at pains to abase themselves somewhat, to show that they know the terrain by sacrificing some dignity without losing all credibility. Many readers, meanwhile, may be willing to ponder how they fail or why they fear it, but few will pick up a book for people who think of themselves as “failures.” Add to this the fact that all books fail to be everything their authors hoped and that almost all books fail to sell, and it becomes clear why books about failure remain few and far between. So how do we learn to stop worrying and love it when we bomb? 

These two authors appear to have worried about failure more than they have experienced it. Sarah Lewis, an art historian and curator who was named to O, the Oprah Magazine’s 2010 “O Power List,” celebrated her past and future failures in her college application essay (she went to Harvard) and alludes to life lessons from a janitor grandfather. Lewis invites us to think deeply about failure as a “gift” that is essential to creativity. Megan McArdle earned her M.B.A. but graduated after the dot-com bust, moving back into her parents’ New York City co-op and working part-time in her father’s firm. Eventually, she blogged her way into a journalism career at The Economist and an array of impressive print and online outlets. In “The Up Side of Down” McArdle wants to teach us how to “fail well” by changing how we react to inevitable setbacks. 

Lewis’s voice is so lyrical and engaging that her book, “The Rise,” can be read in one sitting, which is so much the better since its argument is multilayered and needs to be taken whole. The book’s title  exalts the hidden or “outworn, maligned foundation” that can lead to unexpected innovation. The gift of failure, she observes, is akin to the gift of grief. After pain and loss may come a new appreciation of incompleteness and therefore of possibility. Lewis perceives “an ever onward almost” in surrenders, near wins and the perpetually unfinished masterpiece. “Managing the gap between vision and work, which often looks to others like being swallowed by failure, is a lifelong process,” she writes. Failure is ever-­present in the unending drift toward mastery.

McArdle has written a more straightforward if not traditional self-help book. “Since we cannot succeed simply by not failing,” she writes in “The Up Side of Down,” “we should stop spending so much energy trying to avoid failure or engineer it away. Instead, we should embrace it — smartly.” In lieu of seven effective habits, she recommends failing “early and often,” teaching failure in schools, making it easy to recover, shedding biases that keep us from perceiving our mistakes, distinguishing between novice errors and criminal ones, resisting the instinct to blame, and erring on the side of forgiveness. Rooting her advice in American exceptionalism, she remarks: “Failing well can’t be that hard, because America spent several centuries being really good at it. We’re the descendants of failures who fled to these shores from their creditors, their failed farms, their disastrous love affairs. If things didn’t work out in New York, we picked up and moved to North Dakota. Somewhere along the way, we built the biggest, richest country in the world. And, I’m going to argue, we did it mostly because we were willing to risk more, and forgive more easily, than most other countries.” 

One need not have descended from involuntary immigrants, Native Americans, the landless, the unloved, the unforgiven or the Pacific Rim to recognize that if Lewis occasionally overthinks, McArdle’s weakness is blunt generalization. In an autopsy of Enron, she pauses to ask, “Why is it easy to get rich in America, and hard to get rich in Zimbabwe?” The answer is “the culture and rules surrounding risk and failure.” In her best chapter, on the crushing emotional and structural costs of long-term unemployment, she offers, “The best way to survive unemployment is to adopt what you might call the Way of the Shark: Keep moving, or die.”

Lewis argues the opposite. “When we surrender to the fact of death, not the idea of it, we gain license to live more fully, to see life differently,” she writes in tribute to a friend who drowned while saving a child, “to walk down paths of my own choosing, which to some might seem like failure.” For Lewis, failure is the progenitor of new thinking and risk-taking. By contrast, McArdle concludes by reminding readers to “understand failure as the natural consequence of risk and complexity.”

Whether one accepts Lewis’s idea that failure is a gift that keeps on giving or adopts McArdle’s advice that failing well is the best revenge depends, of course, on what you understand by “failure.” Neither book can answer that question for readers, and neither author really tries. Early on, Lewis avers that the word has no stable definition, because as soon as we try to rethink it into a boon or an opportunity, failure is no longer failure and again recedes into shadows or silence.

McArdle, for her part, shrugs: “ ‘Failure’ is sort of a junk drawer of a word. We dump all sorts of meanings into it, and then when something goes wrong, we rummage around and pull one out.” This shared evasion is the only serious failure by either author, because it skirts what keeps so many of us awake at night: that we may fail simply by not succeeding, that failure may become an engulfing identity rather than an ennobling opportunity. Regenerative failure is nice work if you can get it, but what if you can’t?

Another view comes from across the Atlantic: Levin noticed something curious: the students who persisted in college were not necessarily the ones who had excelled academically at KIPP; they were the ones with exceptional character strengths, like optimism and persistence and social intelligence. They were the ones who were able to recover from a bad grade and resolve to do better next time; to bounce back from a fight with their parents; to resist the urge to go out to the movies and stay home and study instead; to persuade professors to give them extra help after class. Those skills weren’t enough on their own to earn students a B.A., Levin knew. But for young people without the benefit of a lot of family resources, without the kind of safety net that their wealthier peers enjoyed, they seemed an indispensable part of making it to graduation day.

Duckworth, a professor at Penn State showed in her early research that measures of self-control can be a more reliable predictor of students’ grade-point averages than their I.Q.’s. But while self-control seemed to be a critical ingredient in attaining basic success, Duckworth came to feel it wasn’t as relevant when it came to outstanding achievement. People who accomplished great things, she noticed, often combined a passion for a single mission with an unswerving dedication to achieve that mission, whatever the obstacles and however long it might take. She decided she needed to name this quality, and she chose the word “grit.”  They settled on a final list: zest, grit, self-control, social intelligence, gratitude, optimism and curiosity as the best predictors of success in life. Everyone wants their students to succeed, of course — it’s just that many believe that in order to do so, they first need to learn how to fail.

Or as Winston Churchill put it “Success is stumbling from failure to failure with no loss of enthusiasm.” 

Or more optimistically as Robert Kennedy said “Only those who dare to fail greatly can ever achieve greatly.”

Laughter, the best medicine

Ten years ago, Dr. Madan Kataria burst out laughing for no reason at all. Since then he's helped form over 3000 "laughter clubs" throughout India, toward the goal of creating a million such clubs around the world. "When you laugh, you change," explains Kataria, whose fans include actors Goldie Hawn and John Cleese. "And when you change, the whole world changes around you." 

The unique concept of Laughter Yoga and Laughter Club is the brain child of Dr. Madan Kataria, a physician from Mumbai, India. It is now a worldwide movement with over 5000 clubs globally. Laughter Yoga allows anyone to laugh in a group for 15-20 minutes without depending upon a sense of humor, jokes, or feeling happy. Laughter Yoga combines simple laughter exercises, clapping, and gentle yoga breathing, which turns into real laughter when practiced in a group. Everyone knows that it feels good to laugh! That’s because when we laugh, our bodies release an “inner pharmacy” of hormones and chemicals that have healthful and positive effects on our bodies, minds, and spirit. Research shows that when we laugh, there is an actual chemical change in our bodies that helps to ease pain and relieve physical, mental and emotional stress.


Laughter improves cardiovascular health, lifts depression and strengthens the immune system. It also improves communication skills, creativity, self-esteem and personal relationships. Laughter Yoga has helped many overcome severe shyness. A recent study at Stanford University concluded that laughter stimulates the parts of our brain that use the “feel good” chemical dopamine. And guess what? Vigorous laughter, involving whole body movements, can burn calories! 

Norman Cousins, celebrated author of Anatomy of an Illness, described the benefits of laughter in his recovery from a potentially fatal and very painful disease. He found, for example, that 10 minutes of hearty laughter gave him 2 hours of pain-free sleep. Anatomy of an Illness was the first book by a patient that spoke to our current interest in taking charge of our own health. It started the revolution in patients working with their doctors and using humor to boost their bodies' capacity for healing. When Norman Cousins was diagnosed with a crippling and irreversible disease, he forged an unusual collaboration with his physician, and together they were able to beat the odds. The doctor's genius was in helping his patient to use his own powers: laughter, courage, and tenacity. The patient's talent was in mobilizing his body's own natural resources, proving what an effective healing tool the mind can be.

“I have learned never to underestimate the capacity of the human mind and body to regenerate -- even when prospects seem most wretched. The life force may be the least understood force on earth." Norman Cousins (in his; Anatomy of an Illness)” 

Rather than curse the darkness, light a candle or at least help others to light a candle. Don't snuff out these efforts however little or insignificant they may seem to you but each of these can casts a ripple of hope that can in time become a beacon of hope for the country.

 believe that imagination is stronger than knowledge. That myth is more potent than history. That dreams are more powerful than facts. That hope always triumphs over experience. That laughter is the only cure for grief. And I believe that love is stronger than death.

--Robert Fulghum
