Tunnel through the Earth
Drop a ball through a tunnel drilled straight through Earth. It won't fall forever. It'll oscillate back and forth, popping…
Physics
Physics is one of the disciplines of natural sciences which deals with the study of the basic laws of nature and their manifestation in various natural phenomena.
Physicists attempt to explain several diverse natural phenomena in terms of certain scientific laws and concepts.
Statistical Physics: Ensembles
Ensembles in statistical physics are collections of macroscopically identical but essentially independent systems. I explain the three main types: microcanonical,…
