In a newly-published paper, Lawrence Livermore scientists have defined, for the first time, a set of theoretical boundaries for the absorption of petawatt laser light. Livermore, California (PRWEB) June 24, 2014 The absorption of petawatt (1015 watts) laser light by solid matter is a crucial problem that has been the subject of theoretical and experimental study for more than two decades. In a newly-published paper, Lawrence Livermore scientists have defined, for the first time, a set of...

Efficient Approach To Manufacture 3D Metal Parts Developed By Researchers
2014-06-17 03:15:18

By Kenneth K Ma, Lawrence Livermore National Laboratory Lawrence Livermore National Laboratory researchers have developed a new and more efficient approach to a challenging problem in additive manufacturing -- using selective laser melting, namely, the selection of appropriate process parameters that result in parts with desired properties. Selective laser melting (SLM) is a powder-based, additive manufacturing process where a 3D part is produced, layer by layer, using a high-energy...

Series Of Experiments Show Initial Gain In Fusion Fuel
2014-02-12 14:37:51

Breanna Bishop - Lawrence Livermore National Laboratory Ignition -- the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel -- has long been considered the "holy grail" of inertial confinement fusion science. A key step along the path to ignition is to have "fuel gains" greater than unity, where the energy generated through fusion reactions exceeds the amount of energy deposited into the fusion fuel. Though ignition remains the...

A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology. Specifically, the team used statistical mechanics and mathematical modeling to shed light on something known as epigenetic memory -- how an organism can create a biological memory of some variable condition, such as quality of nutrition or temperature. "The work highlights the interdisciplinary...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
