   I've just had a pedagogic revelation! Here it is:   
      
   Transistor theory is much more effectively taught if explained as a   
   *discovery* (which it was) than as an invention (which it never was).   
   All these decades I've been wrestling with this conundrum and all it took   
   to clear things up was a handful of these amazing mushrooms. Yay! :-D   
   Okay, I was joking. But seriously, think about it. The concept is far   
   more effectively absorbed by students if presented this way.
