# The Geekest T-Shirt Of The Year.... So Far

Staff Emeritus

## Main Question or Discussion Point

I tend to buy at least 1 geeky t-shirt a year, just for the heck of it. I can't not buy this one when I saw it last week at the Chicago's Adler Planetarium during their Members Night.

Most of the people I was with didn't get it. I mean, they knew that it has to be "Force", but they couldn't make the connection. So of course I had to explain to them that mv = p, and that the most general form of Newton's Second Law (F=ma) is F = dp/dt, which is F = d/dt (mv).

You could hear crickets after I explained that, and then followed by "oooohhh....." before they walked away shaking their heads.

I wonder how many of the planetarium guests had the same puzzled look when they saw the shirt. Maybe that's why the shirt was on SALE! :)

LOL. At least you tried!

I saw this t-shirt in my FaceBook feed yesterday, and got a good laugh out of it. At least EEs and Physicists can appreciate it...

And they used the vector expression, which somehow makes it even geekier.

Here's a wacky (and yes - appallingly precocious!) T-shirt idea I thought of and my sister-in-law actually designed. It goes with the Insights article I wrote on the Balmer Alpha line. The pots at the top are the family's unflattering opinion of me!

Where is the model showing off the 1963 shirt now? Probably close to 77 years old...

And what is a "'snow' gift"?

"Snow," transitive slang verb; to "blitz," as in "snow under" with erudition.

When I was a summer student at Fermilab, I found this "ad" for "Bob's School of Quantum Mechanics" (i think it's originally from the "Purdue Engineering Magazine")... i think it was on someone's wall. So, I photocopied it... then later scanned it and digitally touched up what I could. I made a copy available on my university website when I was in grad school. I see it has made the rounds... and is now in someone's CafePress store.
(Someone must have a higher quality copy... maybe someone at Purdue can look though old issues of the magazine.)

I just bought 2 more geeky t-shirts.

I'm going to wear this tomorrow since we will be doing Ohm's law.

And then, in a few weeks, when we will do magnetic induction and force on currents, I'll be wearing this!

See all the things we instructors do for our students?

I don't think I've ever seen that second, "gang sign" shirt. That's really good!

EDIT: I looked for them on line. Quite a few of the offerings are done with a left hand

There IS the Fleming Left Hand Rule, so that is correct as well.

I have a blue T-shirt with that message text, but no big Omega symbol. I got weird enough looks the first time I wore it to work that I decided not to do that anymore. It's now a workout shirt...

(The engineers who saw it at work smiled or smirked, but all the support folks were a bit intimidated by it, not understanding the humor...)

Someone should print $2.5\, k\Omega$ on a t-shirt or 2 500 Ω
