Quiz solutions ...

I have posted a solution for quiz 7 in the usual place. Direct link.

The quiz 8 solution will follow soon, hopefully by morning so you can look it over before Thursday's exam. Most of quiz 8 was straight from the homework questions, so you should be OK on that one ...

UPDATE: A quick solution for quiz 8 is now there too ...

Some relativity notes ...

... are online now.

Scanned handwritten notes, in the usual place.

UPDATE: atomic physics, refraction & lenses, more relativity, and some quantum notes are now there too.

Exam III review

There are some review questions for exam III up on WebAssign now. Recall that chapters 23, 26, 27, and 28 are covered on the exam.

More details on the exam structure will follow today, as will at least hand-written notes from those chapters.

Astronomy Public Night and Public Talk

Highly recommended. Basically the last chances for the semester to see the cool telescope in action ...

-----

The Department of Physics and Astronomy will host a pair of public events this Friday, April 27, beginning at 8 p.m. Dr. Gene Byrd will give a public talk on the Milky Way's nature and outside galaxies, "Spiral Arms in Disk Galaxies: Beautiful Patterns and Dark Matter," at 8 p.m. in 227 Gallalee. Immediately following the talk, the observatory will be open for a close look at the moon and Saturn (weather permitting).

For more information, call the Department office at 348-5050 and ask for the faculty member in charge of the date in question. We also ask that you give us advance warning if you are bringing a large group, so we may plan accordingly. We keep an email listing to be notified as new observatory events are scheduled; email lmonroe@bama.ua.edu to be added to the list.

For future dates of viewings, please visit www.astr.ua.edu/Public.html

Atomic Spectra Lab today ...

Here is the procedure

It is a lengthy but good lab, so we will devote plenty of time to it.

This is almost certainly your last lab too, for what that's worth.

Homework & What's next

We are a bit out of sync on homework right now. Your latest assignment came out earlier today on WebAssign, and is due next Monday at midnight. It covers Ch. 27, Quantum Physics.

The good news is, of course, that there are very few homeworks left this semester ...

For the remaining weeks, we will cover Quantum, Nuclear, and Atomic physics. Time permitting, there will be one special lecture on a "current topic" related to research here at UA. Possibly during dead week.

Finally, exam III has been moved to the Thursday before dead week. I will entertain particularly compelling arguments for other dates.
