Top Physics Stories of 2002

Physics Web has announced the Top 12 physics stories of 2002, a number stretched beyond the usual Top 10 to include human-interest stories like the shortage of women in physics and fabrication-of-data misconduct. Advances in optics were lumped together as one achievement for work as diverse as sub-diffraction limit microscopy and quantum photon cloning. Neutrons were big news, providing insight on quantum gravity and atomic nuclei with neutrons but no protons. Some research was COOL, like Bose-Einstein condensates made from cesium and superconductors made from plutonium. One discovery was HOT, namely nanoscale magnetic logic gates that operate at room temperature. The top discoveries were totally sublime: solar neutrinos change identities on their trip from Sun to Earth, the Second Law of Thermodynamics may be broken (can perpetual motion be far behind?) and microwave radiation from the Big Bang is polarized just like a pair of Neo’s sunglasses. The number one physics story, however, was straight out of Star Trek: creation of “cold” anti-hydrogen gas that could be stored indefinitely as long as it didn’t touch anything while being held in a magnetic field. Maybe the top physics story for 2003 will be the development of a dilithium chamber to put the anti-hydrogen gas into…
