Physics Limericks

Have I mentioned I love order of magnitude estimates?

How Fermi could estimate things!
Like the well-known Olympic ten rings,
And the one-hundred states,
And weeks with ten dates,
And birds that all fly with one... wings.

--David Morin, Harvard University


There's plenty more physics limericks on Dr. Morin's webpage or in his physics textbook.

Y Baad Speeling Iz Gud

Stolen from a friend of mine, who stole it from elsewhere.

The Daye Aftur Tumurrow: Y Baad Speeling Iz Gud

Recently, I've seen many people on the internet trying to correct others' spelling. Unfortunately, in doing so, you are endangering the lives of every good person on earth.

As you all know, Earth rotates on its axis, giving us day and night and stopping any portion of earth from freezing or incinerating. What you may not know is that the primary driving force of this rotation is English teachers. More precisely, English teachers rolling in their graves. Thanks to conservation of angular momentum, for a teacher to spin one way forces Earth to spin the other way. Our ENTIRE EXISTANCE depends on these teachers! To clarify the point, here is a diagram:



But how, you ask, could this possibly be related to the internet? As it turns out, teacher grave-spinning is fueled by only two sources: 1st grade essays, and the Internet. Unfortunately for us, 1st grade spelling has rapidly improved in the last decade, leaving the internet as the only source of terrible spelling. For each idiot on the internet, one teacher spins, and this effect has increased over the past decade to become the only force keeping our planet alive. Misuses of there/they're/their and you're/your are especially potent, and account for over 90% of the Earth's rotational velocity.



Why do you care? Because your life depends on it. I put out as a call to all mankind, PROMOTE BAD SPELLING! It is the only thing between us and a horrible, barren world where everything good is dead. For example, consider the following image (it may be shocking to some, parental consent is advised for young children). The red areas are burnt to a crisp, the blue areas are at roughly -42 Kelvin, and only the yellow portions survive.



To prevent the horrific image just pictured, you must forget the grammar and spelling you have learned. Still, if you choose to continue in your rash action, please at least slow down the damage you cause by including the following in your signature. The repeated posting of such content should be enough to allow those truly willing to solve the problem to do so.

Q u o t e:
Their they're, an tey hav there lewt w/thm. Your so dum you're brane is leik a peenut.

Thank you for reading this, and please, consider the future of humanity when you post.


And because I'm who I am (physicist and daughter of an English teacher), I just had to reply...

For completeness, I must point out that there is actually a secondary source of angular momentum: living English teachers rolling their eyes. However, this is a second-order effect for two reasons. Firstly, angular momentum depends upon the mass and the radius of the object (L=mvr), and eyes are both less massive (m) and smaller (r) that entire bodies, so each individual eye will have less of an effect than each individual body.

Secondly, although it is wel known that teachers (of which English teachers are a subset) have eyes in the backs of their heads (resulting in 4-8 eyes per teacher, depending on whether they wear glasses on any of said eyes), there are stll many fewer living English-teacher eyes than dead English-teacher bodies.

Combining these two reasons, the angular momentum from living English teachers rolling their eyes is expected to be more than four orders of magnitude smaller than the angular momentum from dead English teachers rolling in their graves, and therefore can be safely ignored for the purposes of this argument.

Your Astrological Career!

The Chronicle of Higher Education as a *stellar* article on how to find the best career after college - no more of those fancy schmancy personality tests, instead counselors should just ask your sign.

Took me three readings of the intro/closing paragraphs to figure out that it was tongue-in-cheek, despite my *knowing* the Chronicle wouldn't espouse pseudo-science. Have I mentioned I'm not too good at dry humor?

And my ideal career? Academe! :-P

Aquarius: (January 21-February 19) Like all Aquarians, you are unique. You have the celestial gifts of depth and foresight; you are the shaper of new paradigms. You are probably the voice of your generation. Everyone likes you and thinks you are beautiful, kind, and progressive. You are reluctant to stay in one place for too long: You need your freedom to be who you are, and many other places need to benefit from your wisdom and generosity. To Kill a Mockingbird is your favorite book and movie. Above all, you want to help people, and there is nowhere that they can hide in the long run. Of course, you don't want to be the "tool" of any kind of "institution," but you also know that the children are our future. Consider a degree in ethnomusicology, education, women's studies, ecology, or social work. Once you've grown beyond academe, consider expanding your horizons as a community activist, organic farmer, folk artist, co-op worker, weaver, basement gardener, or astrologer.


...or astrologer...

Hey baby, wanna determine the spring constant of my mattress?

Inspired by this list of physicists' pickup lines and a comment by Allison, here's a few of my own.


  • Physicists are Phun!
  • Physicists do it with simple harmonic motion.
  • Hey baby, what's your resonance frequency?
  • Aw man, I wanna integrate those curves of yours...
  • Astronomers do it in the dark, under the stars, all night long.
  • Stargazing's so cold; let's keep warm together.
  • Bigger is better - my tube's 6" around and 2 ft long.


More if I come up with more - or if you add some!

Math is less my expertise, but this's still to awesome to not post.



I bet it was a project for a kickass Math class.

Today's Astronomy lesson

In local coordinates, besides 0º altitude being the (ideal) horizon, we have two other key points - the zenith at an altitute of +90º, and the nadir at -90º. These are both originally English words, though they're used less often lately. Zenith means "peak, height, best", for example "The pop star was at the zenith of her career." And nadir means "lowest, worst," as in "Britney Spears is at the nadir of her career."

Physics is Love

Earlier this week my students asked me if I'd cancel class on Valentine's Day. I replied of course not, because we all love physics! And to prove my point, check out this little treatise on romance as circuit diagrams. It's a little flawed as I mention elsewhere, but still entertaining and illustrates a point.
