It’s on the tip of my tongue…
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/03/Tip-of-the-Tongue.mp3[/podcast] How often has this happened to you? “So I was talking to...to...oh, you know, that guy, the one in the head office, big hair, bad teeth, only listens to Perry Como records...geez, why can’t I remember his name? It’s on the tip of my tongue!” It’s a common phenomenon, and it’s not just people's names. Sometimes you can’t think of the name of a place, or a food, or a car, or...just about anything. You can feel that the information is in your head, but you can’t shape it into a word. It may be a well-known phenomenon, but it isn’t well-understood. However, new research may have shed a little light on the mechanism involved. One leading explanation for tip-of-the-tongue torment is that when ...Fred Morrison’s wonderful invention, the Frisbee
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/02/Frisbee.mp3[/podcast] Fred Morrison died on Tuesday at the age of 90, one of those people you may never have heard of, but really should have. Morrison invented the Frisbee. Since millions of these and other flying discs have been sold since the 1950s, it’s perhaps a bit humbling to discover, though, that even though throwing a Frisbee well is a skill that can be acquired, nobody has pinned down all the details of the science involved. Morrison, born in Richfield, Utah, said the inspiration for the Frisbee went back to a Thanksgiving Day picnic in 1937 when he and his girlfriend (and future wife), Lu Nay, began throwing the lid of a popcorn tin back and forth. They soon found that a tin cake pan ...Spray-on liquid glass
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/02/Spray-on-Liquid-Glass.mp3[/podcast] “Spray-on liquid glass” sounds like a product you’d see advertised at two o’clock in the morning in an infomercial. It sounds even more like a 2 a.m. infomercial product when you see headlines about it that claim it is “about to revolutionize everything.” Maybe it’d sound more impressive if I used its more formal name, which is “SiO2 ultra-thin layering,” but that’s hard to type, so I’m going to stick with “spray-on liquid glass.” Besides, that’s exactly what it is: an extremely thin layer of glass that can be sprayed onto...well, just about anything. Though it was invented in Turkey, the patent for spray-on liquid glass is held by the German company Nanopool. It consists of almost pure silicon dioxide, a.k.a. silica, extracted ...Fuel from germs
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/Fuel-from-Germs.mp3[/podcast] For years, we’ve been turning crops such as corn, wheat and sugar beets into fuel, using yeast to convert sugar into alcohol. But there’s an obvious problem with this. That stuff we’re turning into fuel is also food for humans and feed for animals. (And as an aside, how come we always call it “animal feed” as opposed to “animal food”? And why don’t we ever refer to “human feed”? Hmm?) A lot of the plant is wasted when you grow crops for fuel or food. The leaves and stems, with their tough cell walls made of cellulose, hemicellulose and lignin, are more of a nuisance than anything else. Wouldn’t it be great if there were a use for what is now plowed ...Social contagions
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/Social-Contagions.mp3[/podcast] Parents (I don’t think I’m giving away any parental secrets here) worry about peer pressure--not least because parents remember how much their behavior was influenced by peers when they were young. The fact is, we’re all influenced by the people around us...and we often think of that influence as a bad thing. As the Bible puts it, “Evil companions corrupt good morals.” And other kinds of companions can have other effects. For instance, an analysis of 12,067 people that appeared in The New England Journal of Medicine in 2007 revealed that you are more likely to be obese if your best friend is obese. (Overstuffed siblings or spouses also makes a difference, but the greatest negative effect comes from fat friends.) To a certain ...Why I’m not Stephenie Meyer
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/Why-Im-Not-Stephanie-Meyer.mp3[/podcast] I’m a full-time writer, but not, alas, a fabulously wealthy and/or successful one. James Cameron isn’t bugging me about film rights; Oprah isn’t plugging me on TV; fans aren’t lugging great stacks of my books around, chasing me for autographs. It’s easy, when you’re one of the little guys in any creative field, be it fashion, books, movies or music, to envy the runaway successes and wonder what, for example, Stephenie Meyer’s got that you ain’t got. Are her books, objectively, truly so much better than everyone else’s? Or, more to the point, than mine? Probably not, suggests recent research: in fact, runaway successes are runaway successes in part because they’re runaway successes...and efforts to figure out what “the next big thing” ...The scientific case for live music
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/The-Scientific-Case-for-Live-Music.mp3[/podcast] Music today is ubiquitous, both in public spaces like malls, elevators and offices and in the very private space between an individual’s ears, courtesy of personal music players. But that’s all recorded music. Live music remains far rarer. Live musicians may occasionally show up in a public space, but you generally have to seek them out. Which raises an interesting question. Do we perceive music differently when we watch it being played than we do when we are only listening to a recording? Michael Schutz is both a noted percussionist and a noted researcher. Currently an assistant professor at McMaster University, he runs a research lab dedicated to studying the cognitive science of music, and the visual component of music is something ...Blame your brain for overeating
[podcast]http://edwardwillett.com/wp-content/upLoads//2009/12/Why-We-Overeat.mp3[/podcast] Put on a few extra pounds over Christmas? Wonder why you feel compelled to eat half a box of chocolates half an hour after finishing your second plate of turkey, dressing, mashed potatoes and gravy? Feel a little guilty? Well, new research offers clues to one of the most baffling aspects of the eternal battle of the bulge: why we keep eating even when we’re full. Short version: blame your brain. When you’re hungry, food looks more appealing than when you’re not: hence the old adage about never shopping on an empty stomach. Previous research has suggested that ghrelin, a hormone the body produces when it’s short of calories, may act on the brain to trigger this behavior. Now new research suggests that this ...The mathematics of pizza slicing
[podcast]http://edwardwillett.com/wp-content/upLoads//2009/12/Pizza-Slicing.mp3[/podcast] It’s almost Christmas, and Christmas means food: turkey, dressing, candy canes, oranges, cranberries, chocolate, and, of course, pizza. (OK, maybe pizza is not the most traditional of foods, but it’s still a popular holiday choice, so humor me.) Pizzas normally come pre-sliced. The question is, and I’m sure you’ve asked yourself this a lot, “How do we eat this pre-sliced pizza in a way that ensures nobody gets an unfair share?” That’s the question, as New Scientist reported on December 11, that Rick Mabry and Paul Deiermann kept asking themselves when they used to share pizza for lunch at Louisiana State University in Shreveport. They kept getting into discussions about the mathematics of slicing it up while ...O Tannenbaum
Time to re-roast an old chestnut, a column I wrote several years that has become fresh in my mind due to the successful completion last night of Operation Dress-the-Tree (to be followed in a few weeks, of course, by Operation Curse-the-Tree as the needle-shedding skeleton is hauled out to the alley). Is there scientific interest to be found in ol’ Tannenbaum? Indeed there is! Consider, for instance a Christmas tree’s incredible capacity to "drink" water. A tree may slurp up six or seven litres when you first put it up, and as much as a litre or two a day thereafter. This seems like strange behavior for something that's dead. But of course, the tree doesn't realize that it's dead. As far as ...

Lost in Translation
Kathryn was a human empath whose world and life had been destroyed when the alien S’sinn slaughtered her parents before her very eyes. Jarrikk was a young S’sinn, an unproven warrior who’d seen his flight mates slaughtered by the humans who’d sought to colonize his world.
As humans and S’sinn found themselves on the brink of war, these two Translators had to work together to find a common ground and avert catastrophe. But whether their Translators’ oath and training could overcome the enemies leagued against them was very much in doubt…

The Bounty Mutiny
The Bounty was a British ship visiting Tahiti in 1789 when some of the crew overthrew the captain, William Bligh, and set him adrift in a tiny boat with sailors loyal to him. The mutiny resulted in a number of trials–both of the men who mutinied and of Bligh for losing command of his ship. These fascinating events have been the source for numerous Hollywood movies, most recently The Bounty. The Bounty Mutiny: From the Court Case to the Movie explores the famous case and the movies it inspired.
