近期，我关注并学习了一个有趣方法，Feynman积分技巧。这个方法在某些方面可以替代复变函数在求取一些比较困难的定积分。 在这篇博文中，Panda博主通过两个例题展示了Feynman积分方法的强大和优美。 博文一开始引用了Feynman本文对该方法的评价， ...

“We followed a new mathematical path, the cluster algebras”, says Johannes Henn, director at the Max Planck Institute for Physics. Cluster algebras were discovered in the early 2000s. They consist of ...

A team of scientists finds a way to evaluate highly complex Feynman integrals. How does the world look like at the smallest scales? This is a question scientists are trying to answer in particle ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
