直到2025年，物理学家实际上有三种不同的方式来描述流体，具体取决于流体的尺度。不同的规则分别适用于单个粒子的微观尺度、由粒子集合构成的介观世界，以及充满像水槽中流动的水这样成熟流体的宏观领域。研究人员在寻找它们之间的联系方面已经取得了进展，但在哈尼 ...

In 1900, the mathematician David Hilbert listed 100 mathematical problems that he felt would be good problems to address in the next century. Many of these have been solved, but some still wait for ...

Boundary value problems in Clifford analysis extend classical complex function theory into higher dimensions by employing Clifford algebras and Dirac-type operators. This field provides a unified ...
