Physicists have confirmed that neutrinos, which are thought to have played a key role during the creation of the Universe, have mass. But scientists know frustratingly little about these fundamental particles.

Researchers at IBM's Almaden Research Center in California have developed a new technique to explore and control magnetism at the atomic level. "We can now position atoms and then measure and control their magnetic interactions within precisely designed structures," said IBM researcher Andreas Heinrich.

Benjamin Lev, graduate student in physics, talks about the atom chip, a device reminiscent of a computer circuit board but designed for cold neutral atoms, and how it is an important new addition to the toolboxes of quantum physics and nanotechnology. Quantum computer hardware and atom laser manipulation are but a few promising atom chip applications.

"This is a web site for young students - and anyone else - who are (like me) thrilled by the challenges posed by real science, and who are - like me - determined to use their brains to discover new things about the physical world that we are living in. In short, it is for all those who decided to study theoretical physics, in their own time."

1.Creativity and innovation always build on the past.
2. The past always tries to control the creativity that builds on it.
3. Free societies enable the future by limiting the past.
4. Ours is less and less a free society.

Just as a moving electrical charge creates a magnetic field, so a moving mass generates a gravitomagnetic field. According to Einstein's Theory of General Relativity, the effect is virtually negligible. However, Martin Tajmar, ARC Seibersdorf Research GmbH, Austria; Clovis de Matos, ESA-HQ, Paris; and colleagues have measured the effect in a laboratory.

YouOS is a snazzy new javascript-based operating system that is unlike many of the web "desktops" you currently see. Instead of just cobbling together some draggable windows, this seems to be a serious effort to create a javascript OS that contains both back end and front end functionality. The tutorials and IDE are particulary interesting!

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.
