Glass

There’s a window above my desk through I’m watching a cold wind blowing leaves down the street. It’s not blowing in my face, however, thanks to a very special material: glass. Glass is an “amorphous solid”– its molecules don’t form a strict pattern, like the molecules of steel or granite, but are jumbled together like …

Big ideas

At this time of year it’s traditional to make resolutions concerning the new year, review the old year or preview the coming year. Well, I don’t normally make resolutions; reviewing the old year is done far better by others; and previewing the coming year would involve precognition–which I don’t believe in. There is, however, one …

Clausotechnolometry: the study of the technology of Santa

A couple of Christmases ago I wrote about aerotarandusdynamics: the study of flying reindeer. In passing, I mentioned their mysterious master, one “Santa Claus.” Now scientists are studying him, too, trying to understand the advanced technology this “jolly old elf” (as one authority describes him) uses yearly in his Christmas crusade. These scientists are “clausotechnolometrists.” …

Christmas trees

It’s that jolly time of a year again when we celebrate new life by murdering 40 million trees. Which, I hasten to add, is simply a dramatic opening and not the beginning of a manifesto for the Evergreen Liberation Front. Fact is, I’m a big fan of the custom of having a Christmas tree. For …

December 1993 science anniversaries

‘Tis the season for December’s science anniversaries, and there’s a biggy this month: the 90th anniversary of the first successful flight in a self-propelled heavier-than-air craft. But first, two other flight-related anniversaries. Twenty-five years ago, on December 21, 1968, NASA launched Apollo 8. The crew of Col. Frank Borman, Lt. Col. William A. Anders and …

Static electricity

  I’m a little nervous as I word-process this column about static electricity, because every computer owner knows (and usually learned the hard way), that static electricity is a Bad Thing. Static electricity, however, has been around longer than computers:  like, forever.  The first time anybody noticed, though, was around 600 B.C., when the Greeks …

Potato chips, popcorn and pretzels

  The Grey Cup just ended, but the Rose, Cotton, Orange and Super Bowl are still to come. It therefore seems apt to delve into a subject with which I have a great-deal of hands-on experience: the Three Ps of snack food, potato chips, popcorn and pretzels. Potato chips were invented in a Saratoga, New …

Headaches

Few afflictions are more common than headaches. Statistics (themselves the cause of many headaches) show that in the U.S., up to 50 million people go to the doctor for headaches annually. They’re continuing an ancient tradition. Around 5000 B.C. in China, acupuncture was the treatment of choice. About 160 B.C., the Greek physician Galen recommended …

Bones

Our bones, being hidden away inside our skins, are not something that we normally think about much. But once you break one, it’s hard to think about anything else. I had an early introduction to the subject when I was seven years old and my big brother broke my arm. Not deliberately: we were rolling …

Fossils

Most people think of fossils as neatly mounted skeletons displayed in cool, clean museums with nicely printed labels at their feet. Unfortunately, says Tim Tokaryk, assistant curator of paleontology at the Saskatchewan Museum of Natural History, they don’t occur that way in nature–though he wishes they did! Tokaryk became interested in paleontology as a volunteer …

Radio

Go on any long trip with several other people, as I did over the weekend, and a major source of conflict is sure to arise: what to listen to on the radio. But amid the debate on the relative merits of country, jazz, Top-40 and oldies (not to mention loud and soft), it struck me …

Telephones

It wowed audiences in 1964 at the New York World’s fair. It’s been “just around the corner” for decades. And now, at last, it’s here: the videophone has arrived. AT&T and MCI will both be selling these picture-sending telephones soon, for anywhere from $750 to $1,500 U.S., as the perfect way to show off new …
