Liquid bandages

This may seem far-fetched, but I got a paper cut from picking up a cardboard box. The box slipped, and when I grabbed it, my finger brushed against the edge, leaving a large gash in my finger. Okay, maybe not “large,” but it hurt a lot and the cut was big enough that it needed to be covered. However, it was right on the joint such that a conventional bandage would overly restrict movement. ...

Airplane ownership

For you newly-minted pilots who have asked me, “should I buy an airplane?” I offer a quick rule of thumb, based on my ten years in general aviation, four years of ownership, and MBA: No. Okay, now that we’ve gotten that formality out of the way, here is some insight into the costs of acquisition and ownership, so you can make the inevitable decision. You have no doubt heard the fairytale that you should consider ownership if you fly more than 100 hours a year because airplanes are an investment. It’s true that my airplane outperformed 11 of my 12 stocks, but if you look at the numbers closely, you’ll notice that buying postage stamps or stuffing the money into a mattress for those four years would have beaten everything. ...

How airplanes fly

About nine years ago I started flying as a way to blow off steam from the stresses of work. As with anything I do, once I got past the initial learning hurdles, I pursued the hobby very aggressively, eventually earning an instrument rating, a commercial certificate (land) and a private pilot certificate in seaplanes. (NB: Flying seaplanes is almost as good as sex.) In March of 2000, I became a delusional airplane co-owner. Yesterday, I came to my senses and sold my share. ...

Fun with Skittles

I’m taking a photography class in hopes that I can improve my technique. We have an exhibition in a couple of weeks, and I’m behind on the number of “exhibitable” (ahem) prints. This weekend I rented a fisheye (16mm f2.8) and a macro (105mm f2.8) lens and set out to take a bunch of photos around the greater Seattle area that I will develop later this week. After obsessively photographing various foodstuffs with the macro lens — there were so many interesting textures — I bought a bag of Skittles for color. My kids instantly recognized the package and, not coincidentally, had a keen interest in volunteering to help me in a fact-finding mission. ...

Monday morning armchair physicist

There’s a great urban legend that says a penny tossed off the top of the Empire State building will impact with enough force to embed itself in the ground. Or, if it hit someone in the head, it would kill them. Last week’s Mythbusters (one of my favorite TV shows) busted the myth experimentally. However, I wanted to understand the math and physics a little better. The theory behind the myth looks straightforward: the Empire State Building is 1,250 feet tall. An object dropped off the top would take 8.8 seconds to reach the ground, by which time it would be moving at 193 miles an hour: ...
