Spin (physics)

In physics, spin refers to the angular momentum intrinsic to a body, as opposed to orbital angular momentum, which is generated by the motion of its center of mass about an external point.

Seeing the First Evidence of the Higgs Boson Particle

Seeing the First Evidence of the Higgs Boson Particle

FORA.tv (Nov. 29, 2012) CUNY's Institute for Theoretical Sciences discusses the discovery of the Higgs boson particle. In July, researchers at CERN, the European Organization for Nuclear Research in Geneva, Switzerland, announced that they found convincing evidence of a new particle called the Higgs boson, using the Large Hadron Collider, the world's most powerful particle accelerator. Sometimes called the "God particle," the Higgs boson is a sub-atomic particle that is a building block of the universe. Kyle Cranmer, Assistant Professor of Physics at New York University, and Neal Weiner, Associate Professor of Physics at New York University, discuss how scientists made the discovery and why it is significant. The NYU Experimental High Energy Physics group has been a key part of a world-wide collaboration in the search for the Higgs boson.

Plasma Research: Combating Bacteria

Plasma Research: Combating Bacteria

Deutsche Welle (Jan. 21, 2013) A spin-off of space research may help solve a huge medical problem. It turns out that a plasma, an form of ionized gas helps to heal chronic wounds by killing off multi-drug resistant bacteria and stimulating tissue growth. Researchers at the Max Planck Institute for Extraterrestrial Physics in Garching are developing new applications for plasmas while doctors at Munich's Schwabing Hospital are testing plasma therapies on patients. The field of plasma medicine is already showing great promise.

The Physics Behind Oracle's America's Cup Victory

FORA.tv (Oct. 4, 2013) The Physics Behind Oracle's America's Cup Victory California Academy of Sciences - African Hall Why go fast? Compared to moving slowly, the advantages seem obvious: find food first, forage more widely, and escape more rapidly! But, in the water, being speedier incurs huge energetic costs, with moving a little bit faster skyrocketing the amount of fuel you need. This trade-off between speed and energy propels the evolutionary race for fish, robots, or sailboats: you have to find ways to go faster with ever-greater efficiency. Over generations, the evolutionary race can produce biological and engineering surprises: distantly related fish and boat hulls that have similar streamlined shapes, materials and construction techniques that manage to both stiffen and lighten bodies and hulls, specialization of propulsive systems, and constraints on making turns and tight maneuvers. While the evolutionary processes employed by nature and engineers are similar, there are important differences in how fish or boats are built. For both kinds of designers, the laws of evolution and physics interact to create and constrain the drive for speed. Dr Long will discuss how robotics research lab studies fast fish! A book signing will follow the talk for Dr. Long's latest book titled Darwin's Devices: What Evolving Robots Can Teach Us About the History of Life and the Future of Technology.
