Margulis says that Gaia is "the series of interacting ecosystems that compose a single huge ecosystem at the Earth's surface. Period."

String theory, hybrid cars, and more. A good five minute introduction, then check out Wikipedia.

Laughter as an ancient and crude social lubricant. Indeed!

A huge collection of arguments against the reality of global warming, and how to approach them.

"Our obsession with physical appearance may not be so shallow after all." Symmetry and youth rule.

Using Mathematica to write a program that generates the Big Bang sound. "The simulation lasts 100 seconds representing the first 760 thousand years of evolution of the universe, and varies the sound intensity to match the cosmic microwave..."

"...if the project is successful, the space-time around a tiny point within our universe will be distorted in such a way that it will begin to form a new superfluid space, and eventually break off..."

"It's a hysterical and spectacular mint-powered version of the Bellagio Fountains in Las Vegas."

"It's surprising and really exciting to know that there is such sophisticated information being passed along in the calls you can hear almost every day."

No longer probably a natural change. Definitely because of humans.

Holy shit. " While touch sensing is commonplace for single points of contact, multi-touch sensing enables a user to interact with a system with more than one finger at a time, as in chording and bi-manual operations."

"With little mathematics, the text explores the most fascinating parts of mechanics, thermodynamics, special and general relativity, electrodynamics, quantum theory and modern attempts at unification."

"Perhaps, she speculates, bees possess some ability to perceive not only light and magnetism but quarks as well."

"Rubinstein should be deeply embarrassed to have babbled on so about a subject on which he obviously knows nothing, and did not even trouble himself to take so much as a superficial look at what actual biologists say on the subject." A rebuttal to the ant

Science and sound experiments. Excellent recordings available.

"Finding water on different regions on Mars has implications for understanding its complex geologic history, the possible existence of past life and the sustenance of potential future astronauts."

Amazing. A folder full of these makes for an excellent screensaver.

"Fittingly, the asteroid carried the provisional designation 2001 DA42, thus commemorating the year of his untimely death, containing his initials, and incorporating the famous answer to the ultimate question of life, the universe, and everything."

"In order to decrease the total amount of energy your heating system has to supply, TURN DOWN THE THERMOSTAT AT NIGHT!"

"Saturn is scheduled to release its probe named Huygens that will actually attempt to land on the shrouded moon [Titan] in early January." "Will the truth be stranger than we imagined?"

Swirling colors!

The famous "Eye of God" composite photo. Stunning.

"Sliding through Earth's shadow, the Moon turned haunting shades of red and orange during the eclipse's total phase. The reddish hues are caused by sunlight scattered and refracted by the atmosphere into the Earth's otherwise dark central shadow region."

Fun things to do with microwaves.

"Flash! You're dead."

"A privately-developed rocket plane will launch into history on June 21 on a mission to become the world’s first commercial manned space vehicle."
