not a lighter note
Take for example, ME2113 Mechanics of Materials I, every lecture the lecturer will show us the errata for the previous lecture. That means, for one whole week every week we have been believing in the wrong things. And when you look at the front cover of the notes, it has that legendary NUS logo there. I thought that old lion retired long time ago? Wow, so the lecturer didn't update his notes for x years already, or the module hasn't been taught for a long time?
hj was asking me in lecture something about the formula in the example. I told him don't bother, since the lecturer will be telling us it's an error next week. -_-"
