Skyscrapers

  “One dark night, when we were all in bed, “Mrs. O’Leary lit a lantern in the shed, “And when the cow kicked it over, she winked her eye and said, “‘There’ll be a hot time in the old town tonight. Fire! Fire! Fire!’” This famous bit of verse doesn’t mention it, and somehow I …

Migration

You know what it’s like: the alarm goes off, it’s dark, the wind’s howling, your nose is cold, there’s a snow drift on the windowsill, the radio is talking about icy streets and flesh freezing in 30 seconds, and you just want to pack up and get out of town. Yes, I know I wrote …

Copernicus

This is not a great month for science anniversaries — but the one really big anniversary is a REALLY big anniversary: the 520th birthday of Nicolaus Copernicus. Copernicus brought forth the radical notion that the Earth was not the centre of the universe: that the Earth moved around the sun, instead of vice versa. The …

Chocolate

North Americans eat 4.5 kilograms of it apiece per year. The Swiss, Belgians, Austrians and others eat even more. And given unlimited resources and no worries about looking like a blimp, I’d be happy to eat even more than that. “It” is chocolate, and most people agree with taxonomist Carl Linnaeus, who labelled the cacao …

Hibernation

It’s finally spring (despite the fact that as I write this there’s as much snow on the ground as there has been all winter) and that means that many lucky creatures are just now waking up from their long winter sleep. Deep in burrows or caves, various ground squirrels, marmots, woodchucks, shrews, hedgehogs and bats …

Antarctica

“So this fingie beaker shows up, first day on the ice. She’s an Antarctic 10, but she’s strictly black tie, no bunny boots, not even diapers. There she is, complaining about the cold while I’m doing the bag drag, listening to all this, and finally I just turn to her and tell her, ‘Hey, it’s …

Hiccupping, itching and sneezing

We like to think we control our bodies. As I type this, my fingers oblg — er, obEY me pretty well, and if I choose to stand up and walk away, my legs won’t argue. Sometimes, however, our bodies seem to have minds of their own: like when we’re hiccupping, itching and sneezing. A hiccup …

Weather forecasting

I know this is a sensitive topic, but sometimes it’s necessary to face life’s unpleasantries. It’s time I wrote about weather forecasting. I know, I know, this time of year it seems like anybody could forecast the weather. “Miserably cold this weekend, but springtime’s just around the corner — not!” But believe it or not, …

Tops and gyros

Frequently I begin my column by delving into my childhood for pleasant memories about some activity or other that just happens to relate to my topic. Not this time. This week, my topic is tops and gyroscopes, and the fact is that as a kid I never saw the point of them at all. Remember …

Recording sound

In 1877, Thomas Edison was experimenting with a way to repeat Morse-coded telegraph messages using a waxed paper tape on which the message was written by a stylus. He noticed that if he pulled an already inscribed tape past the stylus it produced a note, and reasoned that he should be able to use the …

Climate control

Humans (at least, this human) are creatures of comfort; and the story of civilization is, to a certain extent, the quest to keep from being either too hot or too cold. The earliest form of climate control was the fire. Room temperature was controlled by adding (or having the servants add) more wood or coal …

Soaring

The airplane in front of us begins to roll, the 60-metre yellow nylon rope connecting us to it tightens, and suddenly the glider I’m in comes to life, jouncing across the grass airstrip. In seconds we rise into the cloud-studded sky. # All aircraft fly because their wings are shaped so that the air travelling …
