Two roads diverged in a yellow wood, And caused me no small amount of panic For traveling both of them would be good But there simply was no way I could Until I remembered quantum mechanics. So half my wavefunction I sent left And rightward steered the other half Both pieces of me with equal […]

How Not to Control the Weather for Your Dog
I’m rooting around in my bag for a pen, and pull out a laser pointer by mistake. Since I’d really prefer not to be grading, I flip it on and shine it on the floor next to the spot where Emmy is half-dozing. She immediately leaps up (she’s pretty spry for a dog of 12…), […]
Ernest, the Purple Aardvark
Ernest, the purple aardvark Had a long and hairy nose And if you ever saw it, You would really say “Boy I bet you could eat some ants with that thing…” All of the ants in Tasmania Use to run away when they saw him Because if they ran to slowly, [Loud slurping noise] Ernest […]
Conceptual Physics Halloween Costumes 2014
A fine if somewhat intermittent tradition hereabouts has been the offering of high-concept Halloween costumes for people interested in physics, surfacing in 2010, 2012, and 2013. I’m a little too fried right now to do anything all that deep, but I’ll try to offer a few suggestions; see also these particle-physics suggestions from Symmetry magazine, […]
One Does Not Simply Science Into Mordor
I recently shot a bunch of video of myself in front of a green screen, for something that will be revealed in due time. Of course, if you have green-screen footage of yourself, you’re pretty much obliged to do something silly with it, so here’s a quick GIMP-ing of a still from the video (also […]
Entrance Music
The AV Club had a Q&A last week asking “What would be your entrance music?” As a music fan and a sports junkie this is, of course, a nearly irresistable question, though a lot of other things got in the way before I could get around to typing up an answer. I’ve always kind of […]
The Real Pi Day(s)
Today is March 14th, 3/14 in the normal American way of writing dates, so you’ll find a lot of silliness on the web today talking about “π Day” due to the coincidental similarity with the first three digits of π (see, for example, Rhett’s annual post). But, of course, this is an archaic and local […]
Snow Plow Projectile Physics
We got over a foot of snow yesterday and today, so schools are closed. Except Union is a residential college, so we never close, which means I have to dig my car out all the same. Which I did, clearing a path to the unplowed street, then took Emmy for her morning walk. During which, […]
Replacing Gravity
I’m teaching introductory E&M this term, so it’s kind of fun to play around with silly applications of Coulomb’s Law. For example, let’s imagine that gravity suddenly switched off, but we wanted to keep the Earth in its orbit. How much charge would we need to move from the Earth to the Sun for the […]
The Elusive Niskayuna Sloth
[Scene: In the car on the way from soccer to lunch at Five Guys. SteelyKid is in her car seat, studying the Halloween-themed temporary tattoos all over her arms.] SteelyKid: Do bats fly right-side-up, or upside-down? Daddy: From the bat’s point of view, it’s right side up more or less by definition. They do sleep […]
