The Fourteen Lattices of Auguste Bravais

submitted by: SirZerp

This video is made as a primer for Condensed Matter students and is showing the potential energy fields of different Bravais Lattices.

It was made using the Coulomb's law to compute a cube of data. The dataset is then sent to a ray tracer which produces the images in the video. The background colors show the potential energy contours of different charge configurations. The colors red green blue are used in an alternating sequence for adjacent contours.

EINSTEIN'S MESSENGERS, LIGO AND THE SEARCH FOR GRAVITY WAVES

submitted by: nsf
Einstein's Messengers is an Award-winning 20-minute documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory. The video examines how LIGO is spearheading the completely new field of gravitational wave astronomy and opening a whole new window on the universe. It explains how LIGO's exquisitely sensitive instruments may ultimately take us farther back in time than we've ever been, catching, perhaps, the first murmurs of the universe in formation. Above all, Einstein's...

Relative Primitives

submitted by: SirZerp
This video was made to test out a relativistic version of Direct Coulomb Summation and is intended to be displaying fields of different moving charge configurations. Coulomb’s Law is well defined and also that inverse square fields propagate at the speed of light is well known. Hence why not put both into the same equation. In general, the video uses Coulomb's law to compute an observational cube of data. The dataset is then sent to a ray tracer which produces the images in the...

Phase-shift Plasma Turbine - Interplanetary Spaceflight

submitted by: MFerreiraJr
The Phase-shift Turbine consists of a set of concentric coils, axially rotated from each other, and feed by phased RF sources, producing radial and longitudinal sequences, which results in helical moving force, ionizing intake gas/particle/ion, generating continuous unidirectional thrust. It was designed in order to operate in atmospheric environments, mainly during takeoff, and in space to reuse exhaust gases from chemical rockets to booster the overall ISP, enhancing utilization of both...

Souder Trust in Science SLA 2011

submitted by: jcbradley

Lawrence Souder from Drexel University presented on June 14, 2011 at a panel on "International Year of Chemistry: Perils and Promises of Modern Communication in the Sciences" at the Special Libraries Association meeting. His talk covered Trust in Science and Science by Blogging, using as an example the NASA press release on arsenic in bacteria and subsequent controversy taking place in the blogosphere.
