Below is a guest post I wrote on the blog Backreaction. With the permition of the host of Backreaction, I now post is here. You are certainly welcome to read it from its original location.
Why did I become a physicist? This, as normally a question for successful people, appears to be really ...

PI is gonna hold a colloquium this afternoon. Below is the title and abstract.
Speaker:
John Donoghue
Title:
General relativity as a quantum effective field theory
Date:
Wednesday June 14, 2006, 2:00 PM
Abstract:
At low energy and small curvature, general relativity has the form of an effective field theory. I will describe the structure of the effective field theory, and show how it can be used to calculate low energy quantum effects.
It sounds interesting. I will blog this talk provided that it will be really interesting and that I will be able to take good notes. So, not guaranteed.
Below are some of the newly added blogs in my blogroll.
P. P. Cook's Tangent Space. Paul Cook is a PhD student in theoretical physics at King's College, London under Peter West's supervision. He is working on "Symmetries in M-Theory and Branes". His blog is in a high "contrast ratio", worth reading.
Physics Musings. Don't get confused with the famous stringy blog, Musings. This blog is run by Jose Antonio Ortega Ruiz, a Spanish Ph.D. in physics. Many year ago, Dr. Ruiz had to give up physics but to do programming after getting his degree. The amazing thing is that he is coming back to physics now after having been away from physics for a long long time. So he describes his blog as "a tale of a physicist's come back". He also has a touching short essay about his story, here. In his words, "you're never too old".
Collider Blog. Don't be scared. It is just a 2-month old blog but not a collider. Dr. Michael Schmitt is a researcher in particle physics, a member of the CDF and CMS collaborations, and a tenured faculty at Northwestern University. He is obviously not just a physics fan. He wants to show us the excitement, challenge and triumphs of accelerator-based particle physics.
Science Blogs. This is a group blog which already has 44 bloggers and 6069 posts in total. Many independent bloggers gave up their original blogging spaces and joined this group space. So you can see lots of different articles in a single explorer window now. However, I would not like to leave my own place.
LQG Group of NUS. This is the webpage of the LQG group in the National University of Singapore. So far, It is simply a page with useful information for beginners in LQG, however, better than none. I do wish it will have more content in the near future and wish there will be more loopy groups in the world.
Jonstraveladventure. Jonathan Shock has been in Beijing, China for about 8 months. He then wrote several long posts in his blog about the tips of living in Beijing for those who are to attend the conference, Strings'06. If you are not Chinese and will attend the conference or will go there by any chance, you may find his blog helpful. However, the most helpful thing is to find a Chinese student as your friend as soon as you get there.
At String School. Dimitri Terryn is a 21-year-old master's student in String Theory. His blog, in his own words, is about "String Theory and High Energy Physics, as seen from the perspective of a lowely Master's student who is on a quest to figure it all out".
Prof. John Baez posted his latest "This week's finds in mathematical physics". In this issue, he talks about the relation between music and mathematics, especially group theory and geometry. If you never stepped into his wonderful out-of-date-style blog, I would suggest you bookmark his site and read it often. And this name, you certainly should not miss it.
Hi S. McHugh , Thanks for your interest in my blogging! Unfortunately, I should have said that I was not intriguied by that talk. So I forgot what he said quickly and thus would not be able to write anything about it. Sorry! It seems that the speaker hasn't authorized PI to post the video of his talk on the website, probably because he wanted to publish the paper first. If you would wait a bit longer, you might get to know the comments on the talk from other people at PI. Cheers, Y.
Are you ready to write about that colloquim yet? I see it appeared on the arxiv this morning and I read a few pages of it. Looks interesting and I'd like to hear your thoughts.
Hi Yidun,Thanks for the link, and apologies for the contrast on my blog. Maybe when I am finished writing my thesis in September I can think about changing the colours. For now though it's time to keep wearing the sunglasses.Best wishes,Paul

Thanks! That compliment, I can take.
Btw, tomorrow there will a colloquium on loop quantum cosmologyat PI.
you're welcome. and if you can handle a compliment, i should say that your title picture and subtext are very beautiful.
w.r.t. the colloquium: i'll content myself with the paper.

Hi Paul,
You are welcome! I did not mean that "high contrast ratio" is not good. I am sorry for the misunderstanding I caused!
Best, Y.
