Lecture notes for today's lecture are now online here.
I intend to post solutions to the two versions of today's quiz sometime later on in the week.
Also, one other thing which I keep forgetting to mention: feel free to call me just Nathan -- I'm neither a doctor nor a professor, and Mr Carruth just sounds odd! (I suppose 卢老师 would work if we all spoke Chinese, but, well, we don't.)
See you all on Thursday!
