Writing

Last week I wrote about paper, and how much I, as a writer, appreciate it. But even more, I appreciate writing itself: the existence of a system for conveying information by putting marks on paper. What I said about our civilization being built on paper is only half true: our civilization is really built on …

Paper

As a writer (and reader), I have always had a deep affection for a pretty mundane material: paper. After all, making black marks on paper is how I make a living. Our society seems to have a similar affection (or maybe addiction!) to the stuff, because for all our talk of civilization being built on …

Biological control of leafy spurge

In 1987, when I was news editor of the Weyburn Review, I journeyed to a small lake near Maxim to photograph beetles infesting the pretty yellow-flowered plants growing on its steep banks (hey, the news business isn’t all politicians and other disasters!). Today, I’m told (though I haven’t had the opportunity to go see for myself), …

Water softeners

Not long after I first moved into a house from an apartment, I woke in the night to the sound of rushing water from the basement. Groggily, I investigated, visions of finding all my boxes of junk afloat dancing in my sleep-fogged brain, only to discover that all that noise came from a cabinet-sized device …

Space tomatoes

In 1984 NASA put into orbit a schoolbus-sized vehicle called the Long Duration Exposure Facility (LDEF), which exposed various materials to space for six years. NASA should have asked Heinz to sponsor it, because not only were there 57 kinds of materials on board, one of those materials was 12.5 million tomato seeds. Those seeds …

Television

There’s probably no object in your house that is a better example of the impact of science and technology than your television set — and probably no object less understood. Strictly speaking, television really is just “radio with pictures.” Like radio, it’s based on the fact that an electrical current flowing in one wire emits …

The search for extraterrestrial intelligence

This may shock some people, but the concept of life on other planets predates Steven Spielberg’s movie E.T. It also predates Kenneth Arnold’s coining of the term “flying saucer” in 1947 and even H. G. Wells’s late-19th-century novel War of the Worlds. Percival Lowell, in the mid-19th century, claimed to see canals on Mars. Immanuel …

Skydiving

  “Go!” yelled the instructor. Over strenuous objections from brain and body, I let go of the airplane’s strut and stepped sideways into 3,500 feet of air. I fell: two simple words that don’t do the experience justice. I’d been training all day. I was supposed to arch and count to five. I didn’t. Every …

Space stations

  Having recently written about the Human Genome Initiative and the Superconducting Super Collider, it behooves me to write about the third “big science” project now in the works, Space Station Freedom. There was some question last year whether Space Station Freedom would ever be built–the U.S. Congress was considering dropping it from the budget. …

The Saskatchewan Science Centre

Our world is largely shaped by science and technology. (Consider television!) The pace of such science-driven change is astonishing–and accelerating. Today’s young people will face a world we can barely imagine, and to do so successfully, they must be comfortable with and knowledgeable about science and technology. But are they? Comfortable, maybe, but knowledgeable? Hardly. …

Golf

‘Tis the season to chase little white balls over big green spaces, and to contemplate, while combing through waist-high grass, the history and science behind your endeavours. The Romans played a game called “paganica,” chasing a feather-stuffed ball around the countryside with a bent stick, but the Scots usually get the credit (or blame) for …

Superconductivity

  You’ve probably heard of “The Spy Who Came in from the Cold.” Well, now there’s something else that’s coming in from the cold: superconductivity. Superconductivity is not something that orchestra directors aspire to; it refers to a discovery made 80 years ago at the University of Leiden (Holland) by Heike Kamerlingh Onnes, who was …
