Pushing a shovel through snow, planting an umbrella on the beach, wading through a ball pit, and driving over gravel all have one thing in common: They all are exercises in intrusion, with an intrudin...
When humans look at a scene, they see objects and the relationships between them. On top of your desk, there might be a laptop that is sitting to the left of a phone, which is in front of a computer m...
“如果每位研究者，在使用一个物种学名时都能够附上参考文献，那么分类学一定会是影响因子最高的学科之一”，圈子里时常可以听到这样的牢骚。在自然科学的发生发展过程中，对事物性质的区分与对事物变化规律的研究，一直是相辅相成、难分伯仲的。这一点不管是在不同层次的自然对象研究之中，还是在脱离了具体研究实体的纯粹数学领域均是如此。因此对于物种的分类，特别是那些有赖于主观经验的分类，当前的挑战主要还是来自于量化研...
Physicists bring human-scale object to near standstill, reaching a quantum state（图）
量子态 引力 原子尺度
