The kinetic theory of molecules, involving many collisions between particles, leads to the emergence of physical Brownian motion (a). By generalizing the kinetic framework, the study showed the ...

This is a simulation of Brownian motion. Brownian motion is the apparently random motion of something like a dust particle in the air, driven by collisions with air molecules. The simulation allows ...

The energetic collisions "melt" the nuclei, setting free their inner building blocks, so scientists can study the quarks and gluons as they existed at the dawn of time. This is not easy.
