At the quantum scale, tiny particles behave in bizarre ways. One reason for this is the uncertainty principle, which says that the more you know about where a quantum particle is, the less you can kno...
In a laboratory 2 kilometers underground, a crane lowers Matt Depatie, a detector technologist, through a hatch into a white-walled cavern filled with about 7,000 tons of ultrapure water that glows as...
Pain and pleasure seem like simple facts of life, however they are anything but that. Neuroscientists still cannot say why physical pain differs from psychological pain, for instance, or why a loved o...
At first glance, corals present as little more than colorful rocks — piles of lobes, stalagmites, and branches poking out from the seafloor. They are anything but. Corals are complex creatures that fo...
Every four years, the math world’s preeminent awards are given to the finest minds of a generation. The young winners — all under 40 on the first day of the year — have reshaped mathematics and theore...
One of the biggest mysteries in cosmology seems to keep getting bigger. Astronomers have known since the 1930s that the universe is expanding, but in the 1990s, the discovery that this expansion is ac...
In theoretical computer science, the key to cracking tough problems is finding the right tools. Most researchers gravitate toward tools that match the problems they hope to solve, and some devote enti...
达特茅斯大学研究发现,某些简单流体在拉伸应力下会发生类似玻璃的脆性断裂,而非单纯流动。这一发现挑战了“只有粘弹性复杂流体才能断裂”的传统认知,证实了1995年Daniel D. Joseph的理论预言。断裂速度可达500-1500米/秒,且临界应力与粘度相关。该成果对软体机器人、喷墨打印及材料科学有重要启示。
