Graduate Student Journal Club

Series Intro

Journal club is a group of graduate students and scientists, mostly with space science interests, who meet weekly to study and present current research topics. It is an opportunity for the students to become familiar with ongoing active research, to learn about journal material, and to gain practice in giving talks and interpreting results.

Meetings are on FRIDAYs from 12:10 to 1 PM in Room 401 Morse Hall.

While historically this Journal Club has focused on Space Science issues, it is certainly open to participation by students from other (or as yet indeterminate) interests; we cover broader topics such as instrumentation, computational techniques, etc. Usually there are student presentations, as well as presentations from the scientists on various methods and techniques they use in their current research.

We will have our first Journal Club meeting this Friday (Jan. 27) at 1:10 PM in Room 401 Morse Hall.

We will discuss possible topics to be covered in this semester. Graduate students who would like to give presentations during this semester please come and sign up. All others are welcome to come join the discussion and are encouraged to volunteer to give talks, especially topics that are at the level of our graduate students.

If you cannot come this Friday but would like to present a talk, please e-mail us with the title of your talk and the date you prefer to give the talk.

What do I get from giving a Journal Club talk? How about publishing a paper on it!
2005-02-04

Abstract:
This is not a space science talk, but is about a problem in Classical Electrodynamics and Relativity. I guess this is ok, especially because this year is the World Year of Physics, in celebration of the 100th Anniversary of Albert Einstein's "miraculous year" of 1905. The story started in 1921, 16 years after Einstein's paper on Special Relativity, and only 6 years after the beginning of the theory General Relativity, a 21 year old young student, W. Pauli, published a paper (his "Journal Club" report?) reviewing both the theories of Special and General Relativity. (That paper was later published as a book: "Theory of Relativity", which you can still buy now for about $10.) He did something more than just reviewing, he provided his "personal views upon some controversial questions". One question remains controversial even now is whether a uniformly accelerated charge radiates or not. Pauli claimed it doesn't in his book, which surely attracted much opposition later. When I was a student working on my master degree, I was fascinated by this problem and did a Journal review talk for my Electrodynamics course. Later, I also published a paper on this problem providing my 2 cents. I'll talk about this, hoping to convince some students that sometimes giving a Journal Club talk reviewing other people's work can have the benefit of inspiring one's own research.
