The SpeechJammer

[podcast]http://edwardwillett.com/wp-content/uploads//2012/04/The-SpeechJammer.mp3[/podcast] As a writer, freedom of speech is near and dear to my heart. It’s one of the basic principles of the democratic form of government. And yet it seems to be constantly under attack, for one simple reason: it’s easy to say you believe in free speech when people are saying what you agree with. It’s a lot harder when they start saying things you vehemently disagree with. “He/she/they shouldn’t be allowed to say that!” is perhaps a natural human response, but it’s still one that must be overcome if free speech is to flourish. Which is why I find a recent technological development rather disturbing. Imagine if, instead of shouting down ...

The QWERTY effect

[podcast]http://edwardwillett.com/wp-content/uploads//2012/04/The-QWERTY-effect.mp3[/podcast]I took to typing like...well, like a writer to a keyboard. In high school I was always the fastest typist in typing class. Possibly it was genetic: my mother, who worked as a secretary, was a very fast typist. Possibly it was because I was highly motivated: my handwriting was (and is) atrocious. Anyone who has learned to touch type has probably wondered about the peculiar arrangement of the standard keyboard, usually called QWERTY. Why aren’t the letters in, say, alphabetical order? The fact is, some of the earliest typewriters did have keyboards in alphabetical order. But they had a problem: alphabetical order put some frequently used letter pairs too close together ...

Pop! goes nutrition

[podcast]http://edwardwillett.com/wp-content/uploads//2012/03/Popcorn-Nutrition.mp3[/podcast] There’s nothing quite like the smell of popcorn. It makes you think of movie theatres, the circus, the midway. It makes you long for a handful. Or two. Or better yet, a whole bucket. And best of all, just this week some research results were released that indicate popcorn is also a very healthy food! I’ll get to that in a minute, but first, some background. Nobody knows who first popped popcorn, which is thought to have originated in Mexico. Ears found in the Bat Cave of West Central New Mexico were dated to some 5,600 years ago, and 1,000-year-old grains of popcorn found in tombs along the east coast of Peru were ...

Salt-tolerant wheat

[podcast]http://edwardwillett.com/wp-content/uploads//2012/03/Salt-Tolerant-Wheat.mp3[/podcast] Having grown up on the prairies, first in Texas, then in Saskatchewan, I’ve seen, my whole life, the patches of white where nothing grows, out in the middle of the fields. And like most other prairie folk, I’ve tended to call them “alkali.” Fact is, though, that most of them, at least in Saskatchewan, aren’t alkaline at all, but saline. True alkaline soils are low in soluble salts, but have a high sodium content and a high pH (over 8.5, which falls between egg whites and ammonia on the alkaline side of the pH ledger). Saline soils are those with a lot of soluble salts in them, and although estimates vary widely, ...

Plate tectonics

[podcast]http://edwardwillett.com/wp-content/uploads//2012/03/Plate-Tectonics.mp3[/podcast] Our planet may look like a solid ball of rock, but if you could crack it like an egg (not actually something I’d recommend, although it would make for a fun scene in a science fiction novel or movie) you’d find it’s quite fluid inside. And, in fact, the Earth’s solid shell, called the lithosphere, is cracked: broken up into numerous “tectonic plates” that scoot around on top of the more fluid layer beneath, called the asthenosphere. Well, “scoot” might be an overstatement: plate speeds range from around 10 millimeters a year all the way up to a whopping 160 millimeters a year (about as fast as your hair grows). This ...

Days of future past

[podcast]http://edwardwillett.com/wp-content/uploads//2012/03/Days-of-Future-Past.mp3[/podcast] Sometimes people ask me why I like to write about science. There’s all sorts of fancy-schmancy reasons I could come up with about the importance of science to modern society and the wonders of the natural world and the joys of intellectual stimulation—but the truth is, I write about science because I grew up reading science fiction. And you know what? That would have warmed the cockles of Hugo Gernsback’s heart. What’s that? You never heard of Hugo Gernsback? Well, you’re about to! Modern science fiction stands primarily on the shoulders of two writers: France’s Jules Verne and England’s H. G. Wells. Verne played on the public’s interest in burgeoning ...

Segmented sleep

[podcast]http://edwardwillett.com/wp-content/uploads//2012/02/Segmented-Sleep.mp3[/podcast] It’s happened to all of us at one time or another: we wake up in the middle of the night, have trouble going back to sleep, start worrying about the fact we’re having trouble going back to sleep, start worrying about the fact we’re worrying about the fact we’re having trouble going back to sleep...and then the alarm goes off and we spend the rest of the day yawning. Well, a February 22 news article by Stephanie Hegarty of the BBC World Service claims that both science and history suggest we should quit worrying and embrace our midnight wakefulness: that in fact, sleeping without waking for eight hours is an ...

The Rapunzel Number

[podcast]http://edwardwillett.com/wp-content/uploads//2012/02/The-Rapunzel-Number.mp3[/podcast] It’s said that fatherhood changes you. Take me, for instance. Until I had a daughter with long hair, I had absolutely no interest in ponytails. Now I find myself making one every morning (although, thankfully, she’s now able to do her own buns for ballet class—trying to achieve perfect bunhood...bunniness?...was way too stressful for me). I am glad, therefore, to see that science has finally tackled the important question of scientifically predicting the shape of a ponytail. That may sound facetious, but in fact it’s a problem that has perplexed people for at least five centuries: that’s how long ago it was that Leonardo da Vinci considered the question, remarking, in his ...

The Space-Time Continuum: These Are a Few of My Favorite Links

We already live in a science fictional future: your pocket, after all, probably contains a powerful communicator/computer with which you can log onto a world-spanning information network. Not surprisingly, science fiction (though not overly successful at predicting its rise) has taken to this futuristic resource in a big way. But how to choose which sites to visit? Here’s one way: visit the ones I visit! Let’s start with general news sites. I’ve previously mentioned Locus Online, the website of the most important science fiction news magazine. Besides publishing news, links to interviews and reviews and more, there alone you’ll find a links page directing you to more sites than you could possible ...

Mind-reading through technology

[podcast]http://edwardwillett.com/wp-content/uploads//2012/02/Mind-reading-Through-Technology.mp3[/podcast] Most of the time, we don’t really want other people to know what we’re thinking. When a friend starts spouting conspiracy theories or a relative asks what we think of her new tattoo, it’s just as well that only our soothing platitudes are heard, while the words running through our heads remain unspoken Outside of science fiction and fantasy, no one has ever been able to reach into another person’s mind and extract those unspoken words. But that may change in the future, because modern technology is making it possible to see what happens in the brain when we hear someone talking—and because this activity is thought to be pretty much the same whether we hear someone say a sentence, or ...
