This week an international expedition set out for Mt. Logan, Canada’s highest mountain (and yes, it’s still Mt. Logan, not Mt. Trudeau) to attempt to travel through time: to look back 10,000 years to see how climate has changed over the millennia–and how human activities are affecting climate now. Two Canadian scientists will climb to …
Less than a hundred years ago, the Wright Brothers made the first powered airplane flight. Next month, NASA will fly a whole new type of airplane, faster than anything that has flown to date: not just supersonic (faster than the speed of sound) but hypersonic (MUCH faster than the speed of sound). Of course, NASA …
Most people prefer shiny apples to dull ones, crisp French fries to soggy ones, and fresh nuts to stale ones. Enter food coatings. Some are visible and some are invisible, but they’re on much of the food you buy, keeping it fresh-tasting and -looking longer. It’s not easy. After all, the coating has to be …
It’s not easy being an independent filmmaker. Of all the art forms, film is one of the most expensive, requiring specialized equipment and facilities. But filmmaking is like any other complicated endeavor: it gets easier when you pool resources with other individuals involved in the same pursuit. That’s the philosophy behind the Saskatchewan Filmpool Cooperative. …
I enjoy my dreams, which are typically full of James-Bond/science-fictional elements. Sometimes they’re so exciting I regret waking up and not finding out how they end. Maybe I don’t have to. Apparently it’s possible to learn to direct your dream while you’re in it. It’s called lucid dreaming, and researchers at Stanford University have developed …
I’m a cat person. Don’t get me wrong; I like dogs. But I like cats more. (It’s an odd thing: although many dog people absolutely hate cats, I’ve seldom met a cat person who hates dogs. But that’s probably a topic for another column.) One of the nicest features of a cat is its purr. …
The Harding University A Cappella Chorus, when I sang with it, seldom relied on pitch pipe or tuning fork to pitch songs. Instead, we relied on Eve, who hummed pitches as needed–ask her for an A or a C-sharp, and she could produce it, accurately, out of thin air. Eve was one of the estimated …
“Edgy” is an adjective frequently used–maybe overused–these days to describe everything from movies to fashion. The avant-garde, it seems, has become just another marketing niche. But the concept of the avant-garde has a long and honorable history in the art world, where artists are always seeking to be on the edge, to provoke and disturb, …
“I talk to the trees, but they don’t listen to me…” sings one of the characters in the musical Paint Your Wagon. Maybe he’s just not speaking the right language. Far from being inert lumps, plants can and do communicate–both with other plants, and, interestingly, with insects. Of course, we’re not talking Shakespearean sonnets or …
We sometimes throw around the word “addiction” a little loosely. “I’m addicted to Harlequin Romances” someone might say, or, “I’m addicted to CBC Radio.” True addiction, however, isn’t just doing something frequently because you enjoy it, or even a habit that’s hard to break: it’s a complex condition that involves the brain’s biochemistry, genetic factors, social factors, …
“Babies smell good.” I’ve heard more than one person say that over the years, usually a woman, and I’ve always thought that person was, perhaps, just a little strange. The babies I’ve known–always from a distance–didn’t smell like much of anything, and when they did, it was a signal to change their diapers. But since …
“In this age of education and progress, the Science of Health is no longer the exclusive possession of a profession, but is made an open book for those who have the wisdom to learn.” That’s a very modern-sounding statement, isn’t it? But it’s not referring to the Web. In fact, it’s from the preface to …
