Marangoni surfers are small particles that self-propel while straddling a fluid-fluid interface in a way similar to that in which a surfer moves on the surface of a wave. In recent years, self-propelling particles have become the focus of numerous...
The Standard Model of particle physics describes all the known elementary particles and three of the four fundamental forces governing the universe; everything except gravity. These three forces—electromagnetic, strong, and weak—govern how...
Machine learning algorithms can beat the world's hardest video games in minutes and solve complex equations faster than the collective efforts of generations of physicists. But the conventional algorithms still struggle to pick out stop signs on a...
