Quotes from class

I operate under the presumption that lecture-based classes are the most worthwhile when the instructor says funny things.  My favorite lectures at Harvey Mudd were definitely in line with this (e.g. Theomech with Sahakian).  On the flip side, humor can also make an excruciatingly boring or poorly taught class tolerable.  The two classes I’m taking at SDSU right now fall somewhere between these extremes – best lecture ever and excruciatingly boring – but the professors definitely utter some hilarious tidbits as they work to convey the intricacies of stellar atmospheres and galactic dynamics.  Here are some highlights.

Note: I’ve included some brief contextual references for the physically-inclined among you.

In other news, Mike and I had a lovely weekend with his sister Jennifer visiting from Minnesota.  She joined us for many games of the board and video variety, one of my symphony concerts, church and brunch, a trip to the zoo (while I was in class), a walk on Torrey Pines beach at sunset, and many delicious meals out.  The weather was gorgeous, much to her delight.  Today, though, San Diego decided it was time to have 80+ degree temperatures which coincided with my cats going apesh*t for no apparent reason.  I think it works like this: May – October is summer, November – December is fall, January – February is winter, and March – April is spring.  Or perhaps I’ve been living here for too long and have fallen under the delusion that San Diego may actually have seasons?  Yes, that must be it.
