Dear John

Judd Hirsch - now everyone knows him as Alan Eppes from Numb3rs...

The following post has nothing to do with the “Dear John” TV show, as you might have guessed, seeing that screen shot. I just used the title – this post is inspired with John Baez’s latest post on Petri nets.

Very often I find the things I study as an EE student totally useless. Few weeks ago we had a lecture on Petri nets in the Distributed systems course – and today I read John’s excellent post about it. It reminded me of John’s TWF posts about analogies in various branches of physics (electrical engineers could enjoy it starting with week 289).

Thank you John for showing me that there are ways for a mathematician (I doubt I’m a mathematician, but I am certainly not an engineer either) to enjoy engineering courses.
