Do you understand all the numbers here? Explanation of the numbers is left as an exercise to the reader.

Too complicated for you? How about this one?

Of course, there is an error in it. 3(pi-.14) does not equal 9; but that is close enough.

Can you feel your heart beat faster? Are your hands sweaty? Relax! This is just a clock! This lovely new timepiece appears to have been hand-written by that evil math teacher we all had to endure. Each hour is marked by a simple math problem. Solve it and solve the riddle of time. Or, you can just know that “52 – x2 + x = 10″ happens to live in the “7 o’clock” position and be done with it.

If you don’t like this one, you can get a Pi clock

And a bonus triple 9 clock:

Every hour in this clock is represented by three nines. Care to calculate?

Not sure if I like 7, which is 6.99999999 [Please no "proofs" that .999... is same as 1.0]

What is 90 degrees in radians? With this great clock, trigonometry will be a breeze! Inspired by my math teacher, Ms. Pinocci.

We’ll let you figure out the time on this one.

Below is the Atom 561 clock:

This design marks the 80th anniversary of Atmos clocks by the Swiss maker Jaeger LeCoultre
The power source is a capsule that contains gas and ethyl chloride. When the temperature rises, the gas/chloride mix expands and compresses a spiral spring, whereas when the temperature falls, the gas condenses and loosens up the spring. Somehow that equals a constant winding of the clock, so no human intervention is necessary.

Clock that reveals time in text:

From Christiaan Postima. The starting point with this project was a personal study about form & time. I put together more than 150 individual clockworks and made them work together to become one clock. I show the progress of time by letting the numbers be written in words by the clockworks. Reading clockwise, the time being is visible through a word and readable by the completeness of the word, 12 words from “one” to “twelve”. The size of the clock is 1,4 by 1,4 meter.

It is a 84 year clock. Source

Planetary orbit clock

little metal planets orbit a larger central planet at the middle of the “universe.” One planet signifies hours, another minutes, and the last tiny planet is the second hand. You can really only tell what time it is by viewing the clock from above, a small price to pay to show off your geek-power. Source Ebay and Gizmodo

Last year, there was an issue with how Verizon quoted the price of wireless data plan. They were quoting the price as 0.02 cents per kb but charging 0.02 dollars.

You can read all about it here, if you are so inclined. But in response to this basic math problem, Randall Munroe (XKCD fame) wrote the this check to Verizon.

From now on, I am paying all my bills using complex numbers as the dollar amount!

I thought it might be interesting to start gathering up the Physics related Facebook Status Messages that I have been posting on my Facebook account.

Here are some of my favorites.

• Sunny feels the chill from the the LHC (Large Hadron Collider) being cooled to 1.9 Kelvin (-271C; -456F) – colder than deep space. Where did I put my space heater?

• Sunny feels like he’s diagonally parked in a parallel universe.

• Sunny exists purely as a probability density function; he can be at more than one places at the same time.
• Basic research is what I am doing when I don’t know what I am doing.
• Sunny is still searching for Higgs.
• I abhor M theory with every fiber of my being.
• almost finished with the paper, I just has to dot my “i” and cross my “h”.
• Sunny has learned not to store plutonium in a tupperwear container.
• is pondering, if Schroedinger’s Cat walks into a forest, and no one is around to observe it, is he really in the forest?
• Wanted, dead AND alive, Schrödinger’s Cat.

Hopefully we will have plenty more by the time the next Talk Like A Physicist Day comes along (March 14, 2009).

NY Times has an interesting article about the inordinate number of physicists in the Congress.

WASHINGTON — According to the Congressional Research Service, there are only about 30 scientists among the 535 senators and representatives in the 110th Congress, and that is counting the psychologist, the psychiatrist, a dozen other M.D.’s, three nurses, an engineer, two veterinarians, a pharmacist and an optometrist.

But physics is on a roll.

“Go back 15 years, and there weren’t any physicists,” said Vernon J. Ehlers, a Republican who taught the subject at Calvin College in Grand Rapids, Mich., until he was elected to Congress in 1993.

His was a lone voice until 1998, when Rush Holt, assistant director of the Princeton Plasma Physics laboratory, won election from New Jersey as a Democrat. And today there are three, adding Bill Foster, a physicist at Fermilab and another Democrat, who won a special election in March in Illinois.

“If we continue to reproduce in this manner,” Mr. Foster began, and Mr. Ehlers finished the thought, “the entire Congress would consist of physicists!”

And the reason why there are so many physicists in the congress:

“Physicists are versatile,” Mr. Ehlers said. “We live in the real world.”

And Vernon J. Ehlers also quipped:

“We’ve done the calculation,” Mr. Holt said. “By midcentury, I think, we’ll have a functioning majority.”

I bet it was a back of the envelope calculation, correct within an order of magnitude. So the physicists majority will happen sometime between 2050 and 2550…

great! I can’t wait. I wonder when will we have our first Physicist President?
