Chicon 7: the 70th World Science Fiction Convention

(Note: if you’re thinking this doesn’t exactly read like a typical convention report from a SF writer, that would be because this is actually my weekly science column. A slightly different version will be my column for the next issue of the Saskatchewan Writers Guild newsletter Freelance. Never let a convention go to waste! (The …

A half-billion years of irritation

Just a couple of years ago, I wrote a column about the advent of tearless onions that included some background on why onions make us cry in the first place. Ordinarily I wouldn’t revisit a topic quite so soon, but you know how it is with science: things change fast, and just this week there …

Measurement

[podcast]https://edwardwillett.com/wp-content/upLoads//2009/11/Measurement.mp3[/podcast] “Inch-worm, inch-worm, measuring the marigolds…” Despite that line from a popular song, the fact is, inch-worms don’t measure anything. Neither to cockroaches, bulldogs, llamas or horned toads…because measurement is the process of counting how much of a sensory signal exists, and so far as we know, no other animals can count. Simply counting things …

Honeybees in decline

Honeybees, particularly in the United States, are in decline. In 2007-2008, 36 percent of apiaries surveyed by the Apiary Inspectors of America and the U.S. Department of Agriculture reported that some of their colonies had simply…disappeared, a phenomenon known as Colony Collapse Disorder, or CCD. In the most recent survey, covering September 2008 to April …

The thrill of the chase

[podcast]https://edwardwillett.com/wp-content/upLoads//2009/09/The-Thrill-of-the-Chase.mp3[/podcast] I had a hard time getting started on this column. See, as I was calling up the items I’d starred in Google Reader as possible topics, I thought it wouldn’t hurt to do a quick search for new reviews of my latest novel. And then I thought, well, as long as I’m online, maybe …

Montreal WorldCon: the science column

Every now and then I attend a science fiction convention, and when I do, I like to talk about it in this column, as part of my ongoing evangelical campaign to raise the profile of science fiction and win the genre new readers. Well, I just finished a doozy of a convention, the grandaddy of …

Talk to the right ear

[podcast]https://edwardwillett.com/wp-content/upLoads//2009/06/Talk-to-the-right-ear.mp3[/podcast] If someone approaches you from your left side and makes a request, are you more or less likely to grant that request than if he approaches you from your right side? If you’re thinking, “What kind of a stupid question is that?”, and you think it would be an equally stupid question no matter …

Are cognitive shortcuts making us fat?

[podcast]https://edwardwillett.com/wp-content/upLoads//2009/06/Cognitive-Shortcuts-to-Obesity.mp3[/podcast] When we think about how we make decisions, we tend to imagine that we consider the facts of a situation carefully and logically, in a straightforward, step-by-step manner. But that process is, indeed, imaginary. The truth is that our brains prefer to do as little actual thinking as possible. They like shortcuts—and sometimes those …

The Canadian Light Source

Given that the Canadian Light Source in Saskatoon produces light a million times brighter than the sun, you might well expect to be able to see it at night even from Regina. Or, upon visiting it in winter, you might think you would find thousands of sun-starved Saskatchewanians lying all around it on beach-towels in the snow, …

Cat senses

It’s said there are cat people, and there are dog people. Personally, I like both, but if I had to state a preference, I’d probably give the edge to cats. It’s not very often I have an excuse to write about them in this column, but this week I do, because by some coincidence, two …

Bacteria on a chip

There’s an old science joke that goes, “If it stinks, it’s chemistry, if it’s green and slimy, it’s biology, and if it doesn’t work, it’s physics.” Now, however, scientists are messing with these once-sacred boundaries, as they attempt to combine living cells and computer chips to create tiny, inexpensive pollution detectors. Many cells contain mechanisms …

Cassini-Huygens

If you’re a kid interested in astronomy, as I was, there are few thrills to compare with your first view of the rings of Saturn. So you can imagine how excited astronomers (and ex-kids like myself) are with the imminent arrival of the International Cassini-Huygens Mission at Saturn. The $3 billion space probe, launched October …
