Warming Up to Criticality: Quantum change, one bubble at a time
Physicists can now observe matter as it gradually turns into a Bose-Einstein condensate—the exotic state of matter that displays quantum behavior at macroscopic scales.

The New Black: A nanoscale coating reflects almost no light
A "carpet" of microscopic filaments sprayed onto a surface can prevent it from reflecting light, a potentially useful trait for technologies from solar cells to fiber-optic communications.

Breaking a molecule’s mirror image
The theory of entanglement explains a newly observed behavior in a symmetrical hydrogen molecule: When the molecule fractures, the directions in which its constituent particles move are not always random.

Waves from the Big Bang: Upcoming detectors may view newborn universe
Ripples in space-time may soon give scientists a glimpse of the universe as it looked a tiny fraction of a second after its birth.

The mystery of the missing mass
Researchers found that, for one kind of particle at least, being located inside a nucleus slightly reduces its mass.

Global Number Cruncher
With a colorful, animated slide show, this Web site introduces visitors to the way vast streams of physics data will flow, starting later this year, from the world’s most powerful particle accelerator to 7,000 physicists around the world. Potentially packed with revelations about matter, energy, and the universe, some 15 million-billion bytes of information per […]

Snow Crystals
This Web site, created by Caltech physicist Kenneth G. Libbrecht, is all about snow crystals and snowflakes. With many beautiful images, it provides a guide to snowflakes, information on growing snowflakes, an introduction to the physics of snowflake formation, and ideas for snow and ice activities.
