Physicists have verified a key prediction of Albert Einstein’s special theory of relativity with unprecedented accuracy. Experiments at a particle accelerator in Germany confirm that time moves slower ...

We study dioecious (i.e., two-sex) branching particle system models, where there are two types of particles, modeling the male and female populations, and where birth of new particles requires the ...

A key feature of quantum physics is the wave-particle duality: the tendency of physical systems to exhibit both wavelike and particle-like behaviors. One particularly striking example of the ...
