Nathaniel's on the schedule for seminar snack this week.

Our next department colloquium is this Friday (at 12:30 in SC 199). The talk will be about gender bias (and measuring it) in the classroom environment. It looks interesting. Here's more info.

The assignment for week 5 [pdf] is about dust. A few things to hand in on Monday and other things on Wednesday (plus a strong urging to bring notes on some other topics I enumerate in the assignment). We're reading Ch. 4 in D&W and also a short conference review paper by Bruce Draine. We will start the seminar meeting with continued discussion of the Boomerang Nebula.

Upcoming Events

Check the departmental colloquium schedule. As members of the department, you are expected to attend these talks. Some of them may even mention the ISM.

There are telescope public viewings the second Tuesday of each month, at the Peter van de Kamp Observatory on the roof of the science center. The next one is on October 11, at 9 PM. Further information is available. I'd welcome help from any of you in running these events.


Class Information

Our primary textbook (and the only one I will require you to buy – you'll want to bring your copy to seminar each week; and it is small, paperback, and inexpensive) is Dyson and Williams's The Physics of the Interstellar Medium (2nd ed.) We will supplement it with a lot of other reading, all of which will be available in Cornell Library and/or online. The College bookstore will stock Dyson and Williams, but you might want to buy it online instead. It is paperback, and available both new and used. Make sure you get the 2nd edition (published in 1997).

posted Aug 28: Please read this information about accommodation [pdf] and let me know if there's anything you'd like to talk about – I'm happy to do whatever I can. Or talk to Leslie Hempling in the Deans' Office directly.

posted Aug 28: Everyone will bring snack to seminar two times during the semester. Consult the snack schedule and put your dates in your calendar.
