Dr Hinton also, for good measure, tweaked Dr Hopfield's networks using a branch of maths called statistical mechanics to create what are known as Boltzmann machines.

此外，Hinton 博士还利用数学的一个分支“统计力学”对 Hopfield 博士的网络进行了改进，创造出了所谓的玻尔兹曼机。

And those laws turn out to be preciselythe three key theories of 20th century physics: general relativity, quantum mechanics, and statistical mechanics in the second law.

而这些定律恰恰就是20世纪物理学的三大关键理论：广义相对论、量子力学和第二定律中的统计力学。
