Soap

As any child of the television age knows, among the most important decisions one faces in life is which kinds of soaps and detergents to use. The consequences of not having clothes that are cleaner than clean and brighter than bright, or of using the wrong brand of cleanser on your pearly skin, are too …

Bicycles

I wouldn’t call myself a “serious” cyclist, since I don’t wear neon Spandex shorts and top, a colour-coordinated helmet, leather gloves or fancy cycling shoes. Heck, I don’t even have a water-bottle. But I do cycle a bit, and as I was puffing my way along the bike path the other day it seemed to …

Baseball

I’m lousy at baseball. Fly balls fly right over me, line drives make me duck, and I can’t run the bases worth a darn–but that’s all right, since I seldom hit the ball. So to write this column about the science of pitching, I turned to an expert: Robert K. Adair, Sterling Professor of Physics …

Kites

When Bob Dylan wrote about answers blowin’ in the wind, he must have had Saskatchewan in mind: here on the prairies, just about everything is blowin’ in the wind. (Whether that includes answers depends on how well the kids up the street held on to their homework, I suppose.) You can’t change this fact of …

November 1993 science anniversaries

This month’s science anniversaries begin with a first that was also a last. November 4 marked the 20th anniversary of the launch of Mariner 10, the first interplanetary probe to visit Mercury — and the last of the Mariners. Mariner 10’s main purpose was to photograph Venus, which it did from 5,770 kilometres on February …

Maps

A few years ago in Vienna, while touring with our university chorus, I and three companions, one male and two female, wanted to find our way from the edge of the city to Vienna’s famous giant wooden Ferris wheel. We men, of course, did the logical thing and began studying the subway map. The women …

Frost

We love to see it on trees, we hate to see it on our cars, and we fear it when our tomatoes are ripening: frost. Frost forms when water vapor in the air freezes onto cold objects. The Oxford English Dictionary defines three kinds: “hoarfrost,” the thick, crystalline stuff that makes your backyard look like …

Scientific hoaxes, Part 2

Last week’s column on Piltdown Man was supposed to be about scientific hoaxes in general, but my prolixity defeated me: I had a bunch of left-over hoaxes. In the spirit of Hollywood, therefore, I now present Scientific Hoaxes 2: Lost in My Research. Piltdown Man wasn’t the only fossil hoax. Faking fossils is a tradition …

Scientific hoaxes, Part 1

Science progresses not only when scientists have brilliant ideas, but also when they’re wrong. A wrong idea faces testing through experiments, and those experiments sometimes not only disprove the wrong idea, they uncover the truth. Because of this, science has always been susceptible to hoaxes. A well-executed hoax appears to have solid evidence behind it, …

Tea

  I think my first experience with culture shock came as a small boy when, shortly after we moved here from Texas, a woman we were visiting for supper asked me what I wanted to drink and I said, “Tea.” To my horror, she brought me steaming-hot tea in a small china cup, a beverage …

Insects

You know, if I were an aphid or an ant, or even a cockroach, I’d be pretty annoyed. Over the summer, as usual, mosquitoes got all the press. They were even featured in Jurassic Park. When was the last time you saw an aphid in the movies? In an effort to redress this injustice, I offer …
