Leonardo da Vinci is usually credited with conducting the first systematic study of friction in the late 15th century, a subfield now known as tribology that deals with the dynamics of interacting surfaces in relative motion. Da Vinci's notebooks depict how he pulled rows of blocks using weights and pulleys, an approach that is still used in frictional studies today, as well as examining the friction produced in screw threads, wheels, and axles. The authors of this latest paper used an experimental setup similar to da Vinci's.

And then there is the plumber—perhaps the most vivid example Stiglitz offers of what the future actually looks like in practice. Stiglitz, who likens his own use of AI as “IA” for intelligence assisting, says AI will supplement our labor in the future, and plumbing is a prime example.，详情可参考新收录的资料
绿色通道常态化，意味着审核更快、问询更少。但这也带来一个副作用：一旦你错过窗口期，可能就要等下一轮政策周期。就像2023年的半导体，2024年的低空经济，窗口期就那么一两年，赶上了，几十家企业扎堆过会；没赶上，现在还在排队。，详情可参考新收录的资料
ITE stands for if-then-else. ITE([a-z], leaf(R1), leaf(R2)) means: “if the character is in [a-z], the derivative is R1, otherwise it’s R2”. these trees can nest, splitting the character space into finer partitions as needed. the key insight is that the derivative function never takes a character argument - it produces a complete map from all possible characters to their resulting states in one shot.
