Synchrotrons

  Saskatchewan could soon be home to Canada’s first synchrotron, and if your first reaction is, “So what?” then, dear reader, you must read on. Physicists are a lot like small boys: they like to see what makes things tick by smashing them up. In the case of small boys, those things may be clocks …

Cold

We haven’t been setting any records, but all the same, it’s been pretty darn cold recently. Not that there’s anything new about that. Saskatchewan is a wonderful province and I’m very fond of it, but (I trust I’m not revealing any state secrets here) it’s cold. In winter in Canada, the cold can begin to …

Footballs in flight

In case you haven’t heard, there’s a little football game being played over at Taylor Field next Sunday between a team from Calgary and a team from Baltimore. Canadian football is known as a pass-happy game, so I thought I’d delve into the aerodynamics of a flying football. Football aerodynamics, however, isn’t something you just …

Dry cleaning

Ever since I was a little boy, I’ve wondered something. Somewhere in between the first time I asked myself, “Why is the sky blue?” and the first time I asked myself, “What is the meaning of life?”, I first asked myself, “What the heck is dry cleaning?” The cleaning I knew mostly involved water–lots of …

Mirages

There’s a scene that’s appeared in so many movies and TV shows that it’s become a cliché. You know the one: it’s where this guy is staggering, eventually crawling, through the desert. Cut to a shot of the sun glaring down at him. Cut to a close-up of his parched lips. Cut to a wide …

Radar

With the end of the Cold War, a lot of previously classified military technology is making its way into civilian hands. Spy satellites whose very existence was top secret, for instance, are now being used to survey crops. This post-war transfer of technology from military to civilian use is not new: it happened after the …

Amplification

Summer is the time for outdoor concerts, but even when 20,000 people gather in a muddy field, they take it for granted that they’ll be able to clearly hear the music…and complain if they don’t. We’re so used to electronically amplified sound the only time we give it any thought is when it doesn’t work …

Fireworks

When I was a small boy in Texas, summer meant more than school holidays: it meant fireworks. As Independence Day approached, from any one of hundreds of roadside stands that sprang up out of nowhere you could buy bottle rockets, Roman candles, sparklers, and, of course, Black Cat firecrackers (50 for $1). One of the …

Skating

  In Tulia, Texas, where I lived as a kid before we moved to Saskatchewan, when you said you were going “skating” it was understood it would be on a wooden surface with rollers attached to your feet. Imagine my shock, then, when I found out that up here, “skating” meant sliding on thin metal …

Potholes

It’s spring in Regina, and we all know what that means: snow is melting, water and funny-looking guys in shorts are running, and the potholes are in bloom. Everyone knows that Regina has a pothole problem, and for once, what “everyone knows” is right. But don’t blame the city. Especially, don’t blame Harlan Ritchie, Manager …

Resistors

Recently there’s been quite a lot of talk about new high-temperature superconductors and how they may revolutionize technology. (In fact, some of that talk was mine, since I wrote a column on superconductivity a while back.) Superconductors are materials that transmit electricity perfectly–in other words, materials in which, once electrons start to flow, they never …

Skiing

  I’ve written about the skating, tobogganing and curling, but there’s a major winter sport I’ve yet to explore (and no, it’s not competitive car-boosting). That’s probably because, while I’ve skated, tobogganed and curled, I have yet to strap two long, skinny pieces of fiberglass to my feet and go careening down a mountain or …
