Not exact matches

What struck Barbour most was Einstein's comment that his intuitive leap about space and time had been inspired by Austrian physicist and philosopher Ernst Mach, whose study of the speed of sound in fluids helped explain the sonic boom heard when objects break the sound barrier.

Inflation was conceived in 1980 by MIT physicist Alan Guth to explain why the observable universe is so flat and smooth, with galaxies distributed evenly throughout space and with almost exactly the right amount of mass to balance out its expansion.

In the debris of the collisions that follow, physicists expect to find evidence of yet another strange component of empty space, one that would explain why particles have mass.

As charged particles stream in from the sun, explains Jim Spann, a physicist at nasa's Marshall Space Flight Center in Huntsville, Alabama, Earth's magnetic field deflects them into a long tail that trails behind the planet.

However, two theoretical physicists from the University of Barcelona (Spain) have demonstrated that what occurs on the space - time boundary of the two merging objects can be explained using simple equations, at least when a giant black hole collides with a tiny black hole.

«The cooling impact of sulfate was larger, and the way sulfate interacts with the atmosphere is more straightforward, so sulfate has received more attention,» explains Drew Shindell, an atmospheric physicist at the NASA Goddard Institute for Space Studies in New York City.

But physicists often carry out their calculations in terms of momentum space (also called reciprocal space) rather than ordinary three - dimensional space, Lu explains, and in that framework magnetic monopoles can exist — and their properties match those of Weyl points.

Theoretical physicists used simulations to explain the unusual readings collected in 2009 by the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) mission.

For example, a physicist can show how just two key ideas (Newton's second law and the universal law of gravitation) explain how satellites and space craft are kept moving round the Earth and enable us to calculate the velocities needed to keep these objects in orbit or bring them down to Earth.

CLOUD's genesis is in the mid-1990s, when space physicist Hendrik Svensmark hypothesized that cosmic rays as mediated by solar effects, play a very large role on the physics of climate, and could explain the warming and cooling trends.
