Recent Presentations

In the past two weeks, I have given 3 talks (2 done, 1 planned) on topics in theoretical physics, and thought they may be of used to some people. One is on an introduction into the Swampland Distance Conjecture (DC), the other is on geometrical physics and current hot topics (focus is on QG), and finally a presentation on explicit string calculations, which I am planning on updating since it seems like it could become a small series (the first one is on the Hagedorn temperature).

The DC presentation is done via a derivation from bosonic string theory. It should be noted that in all my presentations, anytime someone is mentioned (a name appears), then it is linked to the referenced paper.

The geometry of physics presentation is solely qualitative (although some technical aspects are mentioned). The main goal was to convey and specify the differences between each field of geometry while showing how they are linked, as well as give a pictorial representation of each field of geometry when it was suitable.

The last presentation on technical calculations in string theory is suppose to show that within string theory, it is not all derivations and finding nice results. There are a lot of calculations and numbers that can be found, which was shown in the Hagedorn temperature example. This problem was pulled from volume 2 of Polchinski's string theory, chapter 11: heterotic strings. This presentation, I plan on updating (and maybe the geometry of physics one as well....).

As a final send off, I took the below photo my first week here at Lehigh University. Pretty campus, but man, is it humid. My northern-made body is not suited for this....

It has been 6 months...

Wow, my last post on my blog was a little over 6 months ago, and well, a lot has happened since. First, I moved to Medford, MA (north of Boston) to attend Tuts University for graduate school in cosmol

Strings ch.6, & an Update

The end of my last undergraduate semester is coming up quick, and I am really trying to end on a high note (all A's to start with). However, to stay somewhat sane after doing all these discrete mathem
