   Format: MarkdownItexI created a stub for _[[Kirchhoff's laws]]_ to go with the $n$Café-discussion [here](http://golem.ph.utexas.edu/category/2012/06/cohomology_in_everyday_life.html#c041746). Maybe somebody feels like expanding it, I don't really have the time for this right now.

   Format: MarkdownItexCan't we just copy in John's [write up](http://ncatlab.org/johnbaez/show/Circuit+theory+I) (if he's happy with this)? I wonder what other parts of associated wikis could be integrated with nLab. At the very least we could point to some of them, e.g., Domenico's [standard model](http://nlab.mathforge.org/domenicofiorenza/show/The+standard+model).

   Format: MarkdownItex[Apparently](http://books.google.co.uk/books?id=XdZNrVdRNKwC&pg=PA1), Bott eagerly told Weyl of this approach when he met him in 1948, and the latter pointed him back to his 1923 paper, which we've been mentioning over [here](http://golem.ph.utexas.edu/category/2012/06/cohomology_in_everyday_life.html#c041755).
