Professor Michael McBride: Okay. So for 150 years organic chemistry courses have tended to acquire a daunting reputation. So you need help. I know you're very able, but trust me, you need help. So where do you [get] the help? The PowerPoints are available on the Web. How many of you've already seen the PowerPoint for today, just so I have some idea? So about a quarter of you maybe. Okay, but anyhow, so your lecture notes are important, but you don't have to worry about getting everything down because you can download it from the Web. And I do it on a Mac, but I try my best to make it compatible with PCs and even with the free PC Viewer for PowerPoint. So you should be able to see it. But I don't see it on a PC. So if anything doesn't come through, let me know so that I can fix it. Okay then, in-class discussion is very important, and if you're really, really shy and can't participate in discussion in class, then email me a question. Okay?
