Nanotechnology 1996

One of the first science-fiction movies I can remember seeing was Fantastic Voyage, the tale of a group of scientists in a submarine who were shrunk to microscopic size and injected into the body of an injured man. Their mission: to vaporize a life-threatening but inaccessible blood clot in his brain. Among other things, the …

Car care

I like my car a lot. But I have to admit, it doesn’t look as good as it used to. And probably yours doesn’t either. That’s because the moment your car rolls out the factory door, its finish starts to deteriorate. It’s not too surprising, since a car’s surface is attacked by ultraviolet light, ozone, …

Paint

It happens every spring. The air warms, the birds sing, the trees bud, the flowers bloom, and people look around at all this natural beauty and say to themselves, “Man, does that fence need painting.” Yes, there’s something about the spring and summer that brings out the handyman–er, handyperson–in all of us. And topping the …

Spring

One hesitates to make a premature pronouncement, but it does appear–at least for the moment–that maybe–and this is only a suggestion, not a prediction, don’t hold me to it–that it could be–although I could be wrong–finally–dare I say it?…spring. Whew! No blizzard blew in as I typed that, so I think we’re okay for the …

Rabbits

This is the time of year when the Easter bunny hops throughout the land, distributing eggs to children (he silliest bit of folklore-cum-advertising gimmick I’ve ever heard, but we seem to be stuck with it). What better topic for a column, then, than rabbits?–which, as anyone who has read Watership Down can tell you, are …

Mathematics

I’m going to say something which, alas, will probably immediately alienate me from a large number of readers: I’ve always enjoyed math. Times tables held no terrors for me, fractions I found fascinating, and algebra–ah, algebra! When I first started taking algebra, I enjoyed it so much I’d make up equations out of thin air …

Candles

There’s something about the flickering flame of a candle that we seem to find irresistible. When we want to create a special mood, or a feeling of warmth and hominess when the weather and the world are cold and frightful, we light a candle–but we seldom meditate on its history and science. As usual, I’d …

ENIAC

Fifty years ago this month, a machine in the University of Pennsylvania’s Moore School of Electrical Engineering solved in 20 seconds an equation that would have required a human mathematician using a desk calculator 40 hours. The feat astounded the world, and launched the age of computers. The machine was the Electronic Numerical Integrator and …

Roses

Valentine’s Day, just past, might just as well be called Rose Day, so popular is that particular flower that day. But few people reflect, as they give or receive these beautiful blooms, on the science associated with them. Allow me to rectify that oversight. The term “rose” is applied to flowering plants that are members …

Algae

They lurk in the water. They look harmless. But sometimes–not always, but sometimes–they can cause sickness: even death. “They” are blue-green algae, and it’s a bit startling to think that algae, something we think of, when we think of them at all, as an unsightly but harmless scum, can be toxic–because most algae, most of …

Seasonal affective disorder

Nobody (nobody human, anyway) likes getting up on a cold winter’s day when it’s still dark and the wind is howling, but for some people it’s more than just unpleasant: it’s almost impossible. They suffer from a form of depression called Seasonal Affective Disorder (also known, appropriately, as SAD). Seasonal depression has probably been around …

Melting ice in Antarctica

Considering how cold it’s been around here recently, global warming sounds not so much like an environmental problem as it does something devoutly to be wished for–but as someone once said, “Be careful what you wish for–you may get it.” While it’s true that science has yet to come flat out and say that global …
