Measuring Magnetic Fingerprints Of Superfluid Helium-3
2013-05-22 13:47:30

Physikalisch-Technische Bundesanstalt Superconducting sensors of PTB allow highly sensitive measurements of the nuclear magnetic resonance of thin helium-3 layers With their SQUIDs, low-temperature specialists of the Physikalisch-Technische Bundesanstalt (PTB) have made it possible for the magnetic moments of atoms of the rare isotope 3He (helium-3) to be measured with extreme sensitivity. With the aid of these sensors, highly sensitive nuclear resonance spectrometers were developed...

Second Sound Observed In A Quantum Gas

University of Innsbruck Below a critical temperature, certain fluids become superfluid and lose internal friction. In addition, fluids in this state conduct heat extremely efficiently, with energy transport occurring in a distinct temperature wave. Because of the similarities to a sound wave, this temperature wave is also called second sound. To explain the nature of superfluids, the famous physicist Lev Landau developed the theory of two-fluid hydrodynamics in Moscow in 1941. He assumed...

Helium Program Is Saved By House Vote
2013-04-29 05:07:31

redOrbit Staff & Wire Reports - Your Universe Online Following a nearly unanimous vote in the US House of Representatives to keep it alive, the fate of a federal program overseeing the sale of the second-most abundant element in the universe will be in the hands of the Senate. On Friday, the House voted 394-to-1 in favor of maintaining the Federal Helium Program, which was initially created in 1925 in order to combat Germany´s early advantage in the blimp-building industry,...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...

vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
