The Physics of College Tour Guides

So we were touring an unnamed university's engineering department this weekend. It was pretty cool, the vibe was positive, the people were well adjusted and friendly, and all seemed well. Things took a turn for the dire as we stepped into the acoustics laboratory. Tragically, our tour guide uttered an utterly unforgivable sentence... "If I stood back to back with you inside this acoustically silent room and talked, you couldn't hear me because the sound-proofing is so great!" My first

The Physics of Leap Seconds (....whaaat?)

The earth is big and confusing, as is all the magma and magnetic and [insert another alliterative m-word here] magic that goes on inside it. To compensate for some of this magicky nature, the leap second was created. To back up a moment, there are many different time-standards in use today, all of them slightly different, and each of them quite confusing. Two of the most common are the atomic-clock based UTC, and the solar based GMT standard. As we have developed ever more accurate clock

The Physics of Sleeping (whoop whoop!)

Ahh, sleep. Slumber. God's gift to mortals. Sleep is all about comfort. As many a mattress commercial has drilled into my head, not all mattresses are comfortable. There is a supposedly optimal point of squishiness and firmness and pillowness and sleepnumberness and weird-yoga-guy-meditating-on-a-mattress-for-no-apparent-reasonness. In short, different people like different mattresses. The generic want for a mattress, however, is relatively universal. This is due to the way gravity acts

The Fphizyx of Waterproofing

Lately, it seems as if everyone and their mother has a "Lifeproof" case for their iPhone. Seriously. If my mom had an iPhone she would absolutely buy one of these. The logic behind it seems to be that the average life is wet, rough, and crazy (enough said on that subject...) and that one should always use protection. For your phone. C'mon, people. But how do they work? Typically, they contain a series of seals made of a relatively malleable type of rubber. When compressed and then he

The Puh-Fizsixcks of Microperforation

Well, Michael Scott would be proud. We have finally considered all our paper and copier needs and determined that lined, microperforated notebook paper is the key. Microperforation is the strip of tiny holes punched in notebook paper somewhere between an eighth and half an inch from the spine, selectively weakening the paper to tensile forces parallel to the spine. Essentially, it's designed to let you tear out a piece of notebook paper without ripping it or otherwise destroying it. By p
