The beginning of a new science
Over the 45 years since their discovery, neutrinos have changed from being a physics oddity into one of experimental physics' most powerful tools. Here, pioneers John Bahcalland Raymond Davisrelate the evolution of the study of extra-terrestrial neutrinos, and provide some stimulating pointers for astronomers and physicists embarking on new observational ventures.
Where did the 'No-go' theorems go?
With quark-gluon calculations being extremely difficult, physicists have to use their ingenuity to get results. The most popular approach is to use powerful supercomputers to simulate a discrete space-time lattice. A recent workshop examined progress in the field.
Towards the ultimate X-ray source:the X-ray laser
With their ultrashort wavelengths, X-rays are excellent probes of fine structure. An international team at the DESY laboratory has developed a technique for attaining wavelengths of less than 100 nm.
Berkeley Lab's ALS generates femtosecond synchrotron radiation
A team at Berkeley's Advanced Light Source has shown how a laser time-slicing technique provides a path to experiments with ultrafast time resolution.
