Back, again...

It has been quite a while since I have posted something. Not that I did not had anything to say, on the contrary...

Back

Vacations are finally over. Thank God!

Now my last 15 days as an undergraduate students... Yippieee!!

BTW

I forgot to mention. I won a physics award in the Department of Physics. To the students by the students. My award was called "Premio Algebrita" which means little algebra. This is a reference to derivations and how algebra makes equation prettier. The award was given to "the person that solves everything".

It is funny cuz I felt very bad getting this award. The other people nominated included two professors and a 16 year old boy who is also graduating this year.

I guess I help a lot. I do it for the love of science. Thank you!

Vacation

I guess I have some free time finally. I have been able to sleep and rest. Here in Puerto Rico it is customary to have Holy Week free. The Monday after Easter Sunday will be free too, so that gives a grand total of 10 days of happiness! When I return to school I will have approximately 15 days of class left. Wow, I still can not believe that in less than a month I'll graduate and have a Bachelor Degree in Theoretical Physics. Summer is going to be awesome.

Then Stony Brook...

World-Sheet

I have found some free time lately. The best way to relax is to read some String Theory. I have the textbook A First Course in String Theory by Barton Zwiebach. This book is so easy to read. Someone with some background in Lagrangian Dynamics and Relativity can read it and take lots of things out. I am up to chapter 6 on Relativistic Strings.

Basically point particles trace out a curve in spacetime called a world-line. The action of the particle can be written in terms of a line element. Since strings are one dimensional objects, the classical action of a string can be written in terms of the proper area of the surface they trace in spacetime. This surface is called the world-sheet. The classical relativistic string action is called the Nambu-Goto String Action.

It is so cool to learn about this. The only thing that I find scary is a bit of lack of motivation. I guess real motivations will come when one meet QCD and its shortcomings.
