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.
"In my language, I never talk about soulmates," she says. "I don't personally believe that there is one person for everybody... but I do believe that we become "The One" for someone."

彼时，新兴技术正从边缘切入，重构存储生态。比如MRAM（磁阻存储器）兼具SRAM速度、DRAM密度与Flash非易失性，已在车规级MCU、工业控制器中商用，三星、台积电、英特尔等均在持续推进该技术进展。ReRAM（阻变存储器）单元面积小，读写速度是NAND的1000倍，同时功耗可以降低15倍。CXL（Compute Express Link）虽非存储介质，却是内存池化的关键。通过CXL，服务器可将多个DRAM/HBM模块虚拟为统一内存池，大幅提升AI训练效率。Intel、AMD、三星正推动其成为下一代数据中心标配。不过，新兴存储并非要“取代”DRAM或NAND，而是填补其无法覆盖的“价值缝隙”。未来将是“传统+新兴”的分层共存格局。，这一点在雷电模拟器官方版本下载中也有详细论述
