      I started watching this 2008 EE lecture series because folks said it's really great and I want to know what makes a great EE communicator and I'm a bit under the weather. Answer: just say everything I've ever wished someone would say. Such as:https://twitter.com/starsandrobots/status/930619138426339329 …

      "I make up a lot of notation by the way" this is probably the hallmark of a great STEM lecturer, right? (Especially heartwarming in a survey class — great skill to communicate.)

          With that much H you could use a rack of space heaters as resistors.

          It's easy to buy caps on the order of kilofarads these days. 1F caps actually look pretty unremarkable: http://www.maxwell.com/images/documents/hcseries_ds_1013793-9.pdf …

          For some reason, I don't think of supercaps as capacitors so much as batteries.
