Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded joint in polyethylene ...
Despite all the advertisements for engagement rings and necklace gifts, natural diamonds are imperfect. Their carbon atoms are arranged in a cubic lattice, but they nonetheless contain several types of crystallographic defects ...
Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system. But when systems become complicated—when many particles interact with one another, in ...
When an athlete swings upside down atop a 7-meter (23-foot) pendulum, it may seem like a feat of strength, courage or technique. A new study suggests it is something more fundamental: a striking demonstration of how intelligence ...
