Computer simulation using particles J.W Eastwood, R.W Hockney
Publisher: IOP

Tiny particles are making a big difference in the world of cancer therapy. Using an exotic form of silicon could substantially improve the efficiency of solar cells, according to computer simulations by researchers at the University of California, Davis, and in Hungary. Computer simulations show that when a light particle (blue wave on left) hits a crystal of a high-pressure form of silicon, it releases two electron-hole pairs (red circles/green rings), which generate electric current. The effect of structural disorder on the stress response inside three dimensional particle assemblies is studied using computer simulations of frictionless sphere packings.

Plato's Allegory of the Cave, Descartes' evil demon, Putnam's brain in a vat -- these are all variants of justifications for solipsism, a philosophical idea that says it's impossible to know with any certainty whether the world as we experience it is "real" or a simulation projected by some external entity.

After thinking about it, I realized that a creator of a universe is capable of changing the laws of physics and sculpting whatever this universe is, which I can do in a computer simulation. If recent measurements of cosmic ray particles are correct, then we may have the first evidence that the universe as we know it is really a giant computer simulation. Language: English Released: 1988. And SLAC physicists—experts in particle transport—are using computer simulations to make those therapies safer. I read a description of the Particle Mesh (PM) method and a code, by Michael Fellhauer, that uses the method. They found that a superimposed lattice framework by nature imposes a fundamental upper limit on the energy particles can have, a contradiction with quantum chromodynamics10.
