Dramatically Intricate 3-D Universes Tell Important Stories about the Cosmos

August 21, 2014 3:16 pm | by Kelen Tuttle, Kavli Foundation | Articles | Comments

Recently, the Harvard-Smithsonian Center for Astrophysics unveiled an unprecedented simulation of the universe’s development. Called the Illustris project, the simulation depicts more than 13 billion years of cosmic evolution across a cube of the universe that’s 350-million-light-years on each side. But why was it important to conduct such a simulation?

Creating a realistic computer simulation of how light suffuses a room is crucial not just for animated movies like Toy Story or Cars, but also in industry. Special computing methods should ensure this, but require great effort. Computer scientists from Saarbrücken have developed a novel approach that vastly simplifies and speeds up the whole calculating process.

Physicists Create Water Tractor Beam

August 11, 2014 12:57 pm | by Australian National University | News | Comments

Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The group discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will. The new technique gives scientists a way of controlling things adrift on water in a way that resembles sci-fi tractor beams.

Grammatikopoulos simulated two palladium nanoparticles colliding at different temperatures. The hotter the temperature, the more homogenous the resulting product, and the further the atoms in the particle crystallize.

Simulating the Invisible

Every trillionth of a second, Panagiotis Grammatikopoulos calculates the location of each individual atom in a particle based on where it is and which forces apply. He uses a computer program to make the calculations, and then animates the motion of the atoms using visualization software. The resulting animation illuminates what happens, atom-by-atom, when two nanoparticles collide.
