A Brief Addendum

It is with great shame that I issue the following public apology. In a previous post, since deleted for the safety and well-being of this community's physics students, I committed crimes against humanity, and even worse, crimes against physics. I claimed that if one were to stick a knife into an outlet, they would not be electrocuted because the circuit could not be completed. This would be true in a vacuum, but I failed to take into account the fact that in being connected to the ground, one wo

Planes

A major concern for planes in a harsh winter climate like our own is the threat of ice forming on the wings. This could potentially interfere with the lift caused by air passing over the wings and cause the plane to cease to function properly. Currently, ice is dealt with by spraying the wings with a deicing agent. This chemical lowers the melting point of the ice, causing it to melt. This process works most of the time, but it can be extremely expensive. That's why smart people have come up wit

Trains

Possibly the coolest form of transportation is undoubtedly trains. They're just so darn cool. While some might write off trainsportation as a relic of the days of Manifest Destiny, it's actually becoming much more useful and cool thanks to science. The newest generation of trains does not run on short men in conductor hats shoveling coal into an engine: they run on magnetism. The trains work by strapping a very powerful magnet onto the bottom of the train and having another very powerful magnet

A Few Thoughts...

Last weekend I attended the high school's production of All Shook Up. It was a nice show but a few things stood out to me. The first was that the string of lights they used in the abandoned fairgrounds scene was wired in parallel. Some of the lights were out, but the rest still shone on, because there was still a path for current to get from one bulb to the other, whereas in a series configuration, a dead bulb would block all current flow and cause the all of the remaining bulbs to go dark.
