Day 399

Canadians had Monday off for Thanksgiving, so I started the week with History of Rock & Roll. Today it was the interregnum between the death of Buddy Holly in 1959 and the British Invasion of 1964. Not much springs to mind musically–in American Grafitti, set in 1962, the “aging gunslinger” John (played by Paul Le Mat) wonders what happened to the good music. However, this was actually the time when surf music made its mark, Phil Spector developed his “Wall of Sound” studio technique and Motown Records got going. So a veritable explosion of genres coming down the pipes that would hit the fan in 1964.

Next week, the Beatles. I’m something of a Beatles fan–it’s the first pop music I can remember listening to–so I’m looking forward to the next couple of classes. Maybe I should bring in Beatles Rockband for the class to play during coffee break.

In Business Ethics, it was workplace discrimination and harrassment. (Actually, that’s what we learned about–there wasn’t actually any discrimination or harassment in class.)

On to FCF, where we cleaned up the last bit of info on filters, namely membrane filtration. Membrane filters use sheets of weird plastics  that due to their molecular structure, have very small pores of uniform size. Unlike depth filters, which can only be given a nominal rating — “we think it will filter particles this size”–membrane filters can be given an absolute size of particle they will filter out. They are washable and resistant to caustic and acid, but they ain’t perfect — they can only be used on beer that has already been coarsely filtered, otherwise the membrane filter will quickly get clogged with yeast and then blow a gasket.

Kind of like any of us when we get too much stuff thrown at us…

    By a bit of a Beatles fan, he means the first day we got him Beatles Rock Band he could sing while playing bass, as he didn’t have to look at any of the lyrics or pitch section.
