Not an April Fool Prank
There’s an option in my tax software to brag on facebook that I’ve completed them. People do this?
Lab Chicken
I recently spent a while unwrapping and eating 64 slices of American cheese about a hundred individually-wrapped connectors, which is a pretty mindless way to spend a few minutes, although it’s better than mindless paperwork or training. Because I lost at lab chicken. Twice in one day, in fact.
Lab chicken, or some variant of it, is an informal game that’s been played out in all places I’ve worked. In its current form, it consists of trying to get someone else to do some tedious task of yours, through either luck or some cunning non-Baldrickian plan (in that it actually works), but not through overt threats or bribery. To the uninitiated, it might seem like an exercise in procrastination, but procrastination in and of itself does not usually invite participation and competition. (Procrastination is often its own reward — not doing an unpleasant or silly task, and often enough, the powers that be change their mind and cancel or scale back what was required. Plenty of positive reinforcement, even without the dispensing of food pellets.)
It’s common practice in our group that when you order something, you are responsible for unpacking it. This usually works quite well, because if you order something you are often the one who is going to use it — a replacement part, flange for a vacuum system, optics or something related — you ordered it because you need it to move along with your project. But sometimes you order parts in large quantities, because you are thinking ahead to the next several months of assembly. So the box may sit on your desk, waiting, until someone actually needs one of the components, and then they are forced to actually unwrap the rest and put them away. That’s what happened to me. I needed a certain connector and was handed the box of “many,” and ended up putting them away.
My other “loss” was when I went to sit down to assemble my little project. Someone had stored several cardboard boxes in the space below the lab bench where I was going to work. Taking a single box down to the recycling bin is a waste of time, so the challenge here is to pile the boxes up until it gets cleared. Since we had some sneetches coming through later on, the pile had to be eradicated. So I got stuck with that task, too.

Built of Facts: A Brief History of Light
A nit (nit being the quanta of disagreement or concern):
Water waves and sound waves need something material to “wave”. Physicists assumed there was a thin and invisible medium called luminiferous aether permeating the universe, and that light waves were oscillations of this substance. But in 1887, Albert Michelson and Edward Morley were able to do a very careful experiment to measure the speed of light as the earth moved through the aether as it orbited in space. Their experiment came up negative. There just wasn’t any aether.
M&M were attempting to ultimately confirm the speed of the earth moving through the ether, via changes in the speed of light, and the reason they knew they had to do this measurement is that way back in 1725, James Bradley had measured stellar aberration — the apparent shift in position of a star due to the motion of the earth, which manifests itself in measurements taken at different times of the year. If the earth were somehow at rest with respect to the ether, there should be no aberration, so this option was already eliminated when the models of electromagnetic wave propagation were being hammered out. The M-M experiment was the experiment that showed we weren’t moving with respect to it, because being at rest wasn’t an option for explaining the null result.
