Physicists capture 'second sound' for the first time — after nearly 100 years of searchingFirst theorized in 1938, heat's wave-like flow through superfluids, known as "second sound", has proven difficult to directly observe. Now, a new technique has finally done it, and could be used to study neutron stars and high-temperature superconductors.
