Physicists observe long-expected helium superfluid phase

Physicists have reported that they have finally observed helium 3 existing in a long-predicted type of superfluid, called the ß phase. This is an important discovery, if it’s borne out, for reasons that partly have to do with its isotope, helium 4. Helium 4 is a fascinating substance because the helium 4 atom is a boson –…… Continue reading Physicists observe long-expected helium superfluid phase

Signs of a slowdown

The way ahead for particle physics seems dully lit after CERN’s fourth-of-July firecracker. The Higgs announcement got everyone in the physics community excited – and spurred a frenzied submission of pre-prints all rushing to explain the particle’s properties. However, that excitement quickly died out after ICHEP ’12 was presented with nothing significant, even with anything…… Continue reading Signs of a slowdown
