The Quantum Physics of Whiteboards

Uncertain Principles: On the Quantum Physics of Whiteboards

The black markers write very clearly on the board, but when I attempted to erase the board at the end of class, the erasers just sort of smeared the ink around leaving a greyish smudge on the board.

From this, we can deduce that the operator W, which describes wiping the board clean, and the operator M, which describes making marks on the board, are non-commuting operators.

Endorsing the Scientific Method

Boobquake determined to prove cleric wrong

Dressing immodestly on April 26th, in order to disprove the statement by a cleric:

“Many women who do not dress modestly … lead young men astray, corrupt their chastity and spread adultery in society, which (consequently) increases earthquakes,” Sedighi said.

Unfortunately, a single test is not enough, since there may well be an earthquake in close temporal proximity to the event. We need lots of statistics.

Update: Jen recognizes this

And yes, I know I need a larger sample size to make this good science. Maybe I’ll include Mardi gras in my calculations.

It's My Party, and I'll Cry if I Want To

Court to hear suit over “Tea Party” name

Nearly three dozen people and groups who called themselves part of the Tea Party movement filed suit against O’Neal and two associates in January, accusing them of trying to “hijack” the movement and confuse the public.

Reminiscent of the tussle between the Judean Peoples’ Front and the Peoples’ Front of Judea. (Thtwike him, centuwion! Thwow him to the gwound!)

Not a Peep Out of You!

Peep Research

There are several important implications indicated by these [low pressure] results:

1. Peeps are poorly equipped as fighter pilots, supporting the Supreme Court ruling that banning peeps from the cockpits of F-16 planes in combat does not violate the Anti-Discrimination Act of 1992. (Orville & Wilbur Peep vs. US Government, 1994)
2. Peeps should exercise caution when ascending after deep-sea diving excursions, as sudden decreases in pressure may exceed the structural integrity of visceral parenchyma.
3. This may explain the tragic demise of the Col. Lewis Peep expedition which attempted to reach the peak of Mt. Everest in the spring of 1856. It is important to note that these data do not exclude alternative theories suggesting that the group was devoured by a pack of diabetic mountain lions. (Schroedinger, Heisenberg, & Bohr, 1922).

One Ringy-Dingy, Two Ringy-Dingy

Over at Cosmic Variance, JoAnne tells a story about dialing Pi on the phone:

Several years ago, before pi-day was famous, a student called the phone number associated with the digits in pi that appear after the decimal point, i.e., 1-415-926-5358. Apparently this is rather common now, and in fact, appears to be promoted as a mnemonic for the first 10 decimal places for those folks we need to have those numbers handy at all times. But this story happened in earlier times, back before the Bay Area split into several area codes. And, as the clever reader has already guessed, that student reached the SLAC main gate. How cool to phone pi and reach the main gate of a major national scientific research laboratory!

I remember the Cesium atomic clock frequency as a phone number: 919-263-1770. It should be a number in the Raleigh, NC region, but there is no listing for it. I’ve never actually called it.
