George Mason University Physics and Astronomy Club

During the spring 2008 semester, we will meet on six Mondays (February 4, 18; March 3, 24; April 7, 21) from 7:00 to 8:30 pm in room 163 of Research I Building on the Fairfax Campus. Visitor parking is available in the Sandy Creek and Mason Pond Parking Decks. Click here or here for a campus map.

GMU Astronomy Observing Sessions are also held on Mondays, following the club meetings; click here for details and schedule.

Feb 4: The Large Hadron Collider and Rainbows

The Large Hadron Collider is the next great particle accelerator. We'll discuss this article from Scientific American. If time permits, we'll also discuss how rainbows come to be.

Problems:

1. You are given three identical thermos bottles, A, B, and C. Thermos A contains 1 liter of 80 °C water; thermos B contains 1 liter of 20 °C water; and thermos C has no water. Empty container D fits easily into any thermos and has perfect thermally conducting walls. You are forbidden to mix the hot water with the cold water. Can you heat the cold water with the aid of container D and the hot water so that the final temperature of the cold water will be higher than the final temperature of the hot water?

2. If you turn on the heater in your room and after, say, one hour you turn it off, will the total energy of the air in the room be raised by the heating?

Feb 18: Astronomy News from Sky & Telescope Magazine

Sky & Telescope's news site has several brief articles on exciting new research. I found these particularly interesting:

Light Echos Give Accurate Cepheid Distance (You may also want to check out the Wikipedia article on Cepheid variable stars)

A Superfast Star from Far, Far Away

Mercury's "Better Half"

A Stardust-Free Comet

Overweight Neutron Stars?

And, here are a couple problems.

March 3: Gravitational Lensing

We'll discuss this review article on gravitational lensing. Don't bother with section 3, which is too technical. Section 4 has several subsections, each on a different observational manifestation of lensing. Perhaps we could each read one or two of these, and share what we've learned with the group.

Here are a couple related problems.

March 24: The End of Cosmology?

Expanding on some of the topics from last meeting, we'll discuss this article from Scientific American.

Here are some problems.

April 7: SETI

We'll discuss this article on the Search for Extraterrestrial Intelligence. Let me know if you are unable to access the link.

Here are some problems.

April 21: The Color of Plants on Other Worlds

We'll discuss this article from Scientific American.

Here are some problems.
