Why do physicists freeze matter to extremely low temperatures? Why is it worthwhile to cool to temperatures which are a billion times lower than that of interstellar space? In his talk, Wolfgang Ketterle, a Nobel laureate, will discuss new forms of matter, which only exist at extremely low temperatures. Of special interest are superfluids which can flow without dissipation. Recently, he and his team have observed a supersolid which is gaseous, liquid and solid at the same time.
