物理学家捕捉到了超流体中热量“晃荡”的最初声音,揭示了热量是如何像波浪一样运动的

In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, moving back and forth somewhat like a sound wave that bounces from one end of a

可变形系统的动力学:研究揭示了索状结构的数学奥秘

Are our bodies solid or liquid? We all know the convention—that solids maintain their shapes, while liquids fill the containers they're in. But often in the real world, those lines are blurred. Imagine walking on a beach. Sometimes the sand gives way und
