Math Tattoo: 6×9=42 - I am sure there is a deep meaning to this

6x9_42_tattoo

Is it because answer to every question is 42?

The number 42 is the answer to life, the universe and everything from The Hitchhiker’s Guide to the Galaxy.

May be stylized 6 and 9 are not numbers at all but represent something else. 6×9 =42 in some different base numbers.

OK, I got it; from the Restaurant at the End of the Universe book:

Arthur pulls random letters from a bag, but only gets the sentence “WHAT DO YOU GET IF YOU MULTIPLY SIX BY NINE?”

“ “Six by nine. Forty two.”

“That’s it. That’s all there is.”

Sometimes I do think that there is something fundamentally wrong with the Universe.

Science books fetch astronomical prices: Copernicus book $2.2M

June 19th, 2008 | No Comments | Posted in Physics Talk

I wrote about the Science book auction a few days ago.

Here is how much was realized for some of the notable books.

GALILEI, Galileo (1564-1642). Le operazioni del compasso geometrico, et militare. Padova: in the house of the author by Pietro Marinelli, 1606.

Image

Price realized : $506,500

KEPLER, Johannes. Harmonices mundi libri V. Linz: Johann Planck for Gottfried Tampach, 1619.

Image

Price realized : $306,000

COPERNICUS, Nicolaus (1473-1543). De revolutionibus orbium coelestium, libri V. Nuremberg: Johann Petreius, 1543.

Image

Price realized : $2,210,500

In all, the total take from Tuesday’s auction at Christie’s New York came to more than $11 million — compared with a pre-sale estimate of $6 million.

To learn how the pictures were taken, please visit here ; but essentially they blew up soap bubbles and took pictures with Sony’s new alpha Series SLR camera.

The iridescent colors of soap bubbles are caused by interfering light waves and are determined by the thickness of the film. They are not the same as rainbow colors but are the same as the colors in an oil slick on a wet road.

As light impinges on the film, some of it is reflected off the outer surface while some of it enters the film and reemerges after being reflected back and forth between the two surfaces. The total reflection observed is determined by the interference of all these reflections. Since each traversal of the film incurs a phase shift proportional to the thickness of the film and inversely proportional to the wavelength, the result of the interference depends on these two quantities.

Thus, at a given thickness, interference is constructive for some wavelengths and destructive for others, so that white light impinging on the film is reflected with a hue that changes with thickness.

 

Gems from Physics History : Science book auction at Christie’s.

June 15th, 2008 | 1 Comment | Posted in Physics Talk

The remarkable collection of a retired physician and amateur astronomer, Richard Green of Long Island, which is offered for sale by Christie’s, contains some of the greatest physics books ever written.

Dr. Green’s library includes works by Galileo, Copernicus, Newton,Gauss, Kepler, and Einstein.

One lot includes 130 reprints from Albert Einstein’s collection of his scientific papers, including his first one on relativity.

Image

Sir Isaac Newton’s Philosophiae Naturalis Principia Mathematica explained the universal laws of gravitation and motion for the first time.

Image

Nicolaus Copernicus’s book “De Revolutionibus Orbium Coelestium” (”On the Revolutions of the Celestial Spheres”). In it, the Polish astronomer laid out his theory that the Earth and other planets go around the Sun, contravening a millennium of church dogma that the Earth was the center of the universe.

Image

Estimate for the Copernicus book: about $1M.

Soon The entire US Congress would consist of physicists!

June 15th, 2008 | 2 Comments | Posted in Physics Humor

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

Image

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?

The Anime Laws of Physics

June 15th, 2008 | 1 Comment | Posted in Physics Humor

Here are select Anime Laws of Physics:

Image

#3 - Law of Sonic Amplification, First Law of Anime Acoustics

In space, loud sounds, like explosions, are even louder because there is no air to get in the way.

#11 - Law of Inherent Combustibility

Everything explodes. Everything.

#12 - Law of Phlogistatic Emission

Nearly all things emit light from fatal wounds.

#15 - Law of Inexhaustibility

No one *EVER* runs out of ammunition. That is of course unless they are cornered, out-numbered, out-classed, and unconscious.

#26 - Law of Feline Mutation

Any half-cat/half-human mutation will invariably:

1) be female
2) will possess ears and sometimes a tail as a genetic mutation
3) wear as little clothing as possible, if any

All of these laws are shown in action in this clip:

Matter of Everything - Teaser and Trailer

June 15th, 2008 | No Comments | Posted in Physics Talk

Matter of Everything.. Hmmm,

A documentary about “no ordinary matter”..

What could it be?

Yup, it’s a documentary about Dark Matter.

THE DOCUMENTARY ABOUT NO ORDINARY MATTER
The Matter Of Everything is a feature documentary that challenges us to see beyond our everyday sense of experience into the unseen universe. From the quantum to the cosmos, The Matter Of Everything journeys deep out of the foundations of nature to reveal what we are, at billionths of the human scale. At that level, physicists at Fermilab, one of the largest particle research facilities in the world, describe a universe that is more unified than ever imagined.

Relationship between math and physics

June 15th, 2008 | No Comments | Posted in Physics Humor

XKCD had a comment about the purity of the subject matter:

Image

A similar joke I have heard before:

Sociologists want to be psychologists, because if you understand the brain you can understand society.

Psychologists want to be biologists, because if you understand life you can understand the brain.

Biologists want to be chemists, because if you understand matter you understand life.

Chemists want to be physicists, because if you understand the universe you understand matter.

Physicists want to be God.

God wants to be a mathematician.

10 Light years to the Inch

The Star Map Crystal is a cosmic paperweight: a 3″ glass cube laser etched with a 3D map of all stars within 5 parsecs of the sun.

Art, Science and Technology

Bathsheba Grossman is an internationally collected artist, working with new and old technology to make sculptures in many materials.

To draw this map, pulses from a focused laser beam are directed into the blank glass. Each pulse of the beam passes freely through the glass except at its focal point, where the concentrated energy causes a tiny fracture. These microscopic sparkles catch the light, forming a permanent map floating inside the crystal.

Random act of science teaching - you weigh less on the way down in the an elevator

Random act of science teaching. These scales were mounted inside commercial and residential elevators allowing riders to test this fact.

Explanation was available as a leaflet in the the elevator.

Everyday physics, tested by everyday person, using everyday objects.
