The laser at 50

[podcast]https://edwardwillett.com/wp-content/upLoads//2010/05/Lasers-at-50.mp3[/podcast] You know you’ve been writing a column a long time when the 50th anniversary of a major scientific discovery comes along and you realize you wrote a column celebrating its 30th anniversary. But that’s exactly what’s happening this month. Next week (Saturday, May 15, to be precise) marks the 50th anniversary of the invention …

The uselessness of celebrity endorsements

[podcast]https://edwardwillett.com/wp-content/upLoads//2010/05/Celebrity-Endorsements.mp3[/podcast] I don’t have much use for celebrity endorsements of, well, anything. Oh, sure, it’s conceivable you could be a talented entertainer and also have an informed, thoughtful opinion that adds more light than heat to the debate surrounding a contentious issue, but just because something is possible it doesn’t mean it’s likely. And let’s …

The ebb and flow of curvy cars

[podcast]https://edwardwillett.com/wp-content/upLoads//2010/04/Curvy-Cars.mp3[/podcast] In the 1940s and 1950s, cars had curves. From the 1960s through the 1980s, they tended to have sharp angles. But since then, they’ve tended more toward the curvy again…although I’m seeing signs of angularity one more. Have you ever wondered why? A German researcher at the University of Bamberg with the unlikely-yet-oddly-appropriate name …

Wooden bones

[podcast]https://edwardwillett.com/wp-content/upLoads//2010/04/Wooden-Bones.mp3[/podcast] It’s easy to not think very much about your bones. After all, they’re securely hidden away inside your body; not visible, except as hard lumps beneath your skin. Funny thing, though: once you break one, it’s hard to think about anything else. When first I wrote about bones, back in a 1993 instalment of …

The Mpemba Effect

[podcast]https://edwardwillett.com/wp-content/upLoads//2010/04/The-Mpemba-Effect.mp3[/podcast] For all that we know about the physical world, there are a few phenomena that, though seemingly simple, continue to baffle us. And one of the most baffling is the Mpemba Effect. You may not know it by that name—I didn’t until I read an article on New Scientist’s website last week—but you’ve probably …

Morally malignant magnets

[podcast]https://edwardwillett.com/wp-content/upLoads//2010/03/Morally-Malignant-Magnets.mp3[/podcast] One of the things that distinguishes humans from animals is moral judgment, our ability to judge other people’s actions in terms of our own sense of right and wrong. Our moral judgment feels so integral to who we are, so much a part of our personality, that it’s a bit disturbing to discover, as …

A half-billion years of irritation

Just a couple of years ago, I wrote a column about the advent of tearless onions that included some background on why onions make us cry in the first place. Ordinarily I wouldn’t revisit a topic quite so soon, but you know how it is with science: things change fast, and just this week there …

Boredom

Everyone is bored sometimes. You find yourself at loose ends, with nothing to read, nobody to talk to, and maybe not even anything interesting to look at…driving alone from Regina to Saskatoon, for example. Yet science has carried out relatively little research on boredom. About four years ago, Richard Ralley, a lecturer in psychology at …

It’s on the tip of my tongue…

[podcast]https://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 …

Fred Morrison’s wonderful invention, the Frisbee

[podcast]https://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 …

Spray-on liquid glass

[podcast]https://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 …

Fuel from germs

[podcast]https://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 …
