Science's 10 Most Beautiful Physics Experiments

Robert P. Crease, a member of the philosophy department at the State University of New York at Stony Brook and the historian at Brookhaven National Laboratory, recently asked physicists to nominate the most beautiful experiment of all time. Based on the paper of George Johnson in The New York Times we list below 10 winners of this polling and accompany the short explanations of the physical experiments with computer animations.

1. Double-slit electron diffraction

2. Galileo's experiment on falling objects

3. Millikan's oil-drop experiment

4. Newton's decomposition of sunlight with a prism

5. Young's light-interference experiment

6. Cavendish's torsion-bar experiment

7. Eratosthenes' measurement of the Earth's circumference

8. Galileo's experiments with rolling balls down inclined planes

9. Rutherford's discovery of the nucleus

10. Foucault's pendulum

clipper's remarks: Barbaric - we have no right to call ourselves developed nations of the 21st century until such scourges are removed from the face of this earth forever and those guilty of these heinous crimes are severely punished. I ask what 'honor' do people speak of when they treat women so degradingly?!

George Carlin

I want you to know, when it comes to believing in god- I really tried. I really really tried. I tried to believe that there is a god who created each one of us in his own image and likeness, loves us very much and keeps a close eye on things. I really tried to believe that, but I gotta tell you, the longer you live, the more you look around, the more you realize...something is FUCKED-UP. Something is WRONG here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption and the Ice Capades. Something is definitely wrong. This is NOT good work. If this is the best god can do, I am NOT impressed. Results like these do not belong on the resume of a supreme being. This is the kind of shit you'd expect from an office temp with a bad attitude. And just between you and me, in any decently run universe, this guy would have been out on his all-powerful-ass a long time ago. [George Carlin, from "You Are All Diseased".]

The Future of Gaming

clipper's remarks: I have tried to capture some hints about the future of gaming. As the author remarks: "For now, the only way to predict the future of gaming is to predict that all predictions will be wrong."

Yet, it seems that in the not so far future, games are going to deeply affect the way we perceive our world. Especially the younger generations will be affected, and to some extent it is already happening. It seems that eventually games will not only affect our perception of the world, they WILL become a substantial part of our world.

Where brilliant thinkers like da Vinci, H. G. Wells, and Mandelbrot inspired much of the world around us today, the world of tomorrow, the very world where we will be spending the later years of our lives, is now being imagined inside the young minds of today’s gamers

When SimCity founder Will Wright introduced his latest project, Spore, demonstrating the next generation organic content builder at the TED conference in 2007, he not only turned heads, but radically shifted the thinking of the entire gaming industry.

Jane McGonigal, a game designer that MIT Technology Review named as one of the top 35 innovators changing the world, and an expert at blurring traditional boundaries, focuses on how the games we play can change the way we experience the real world.

At WIRED Magazine’s 2007 NextFest, special headbands measuring brainwaves served at the controllers for a game called “Brain Ball.

New source of heart stem cells discovered

Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins.

Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells.

These stem cells, located in the surface of the heart, or epicardium, advance the hope of being able to regenerate injured heart tissue.

This finding, published online by the journal Nature on June 22, comes on the heels of parallel cardiac stem cell discoveries in 2006, at both Children's and Massachusetts General Hospital.

"If you're going to regenerate a tissue, you need to regenerate the whole tissue, not just the cardiomyocytes," said Pu. "This progenitor population contains all the potential to regenerate multiple tissue types within the heart."

whether this newly-discovered progenitor is truly multipotent

how multipotency is controlled, and whether this can be used therapeutically to benefit adults with heart failure.
