Common Sense isn’t so Common…

I went to the D programming conference back in August this year, and I ran into several interesting people. One was a former researcher of supergravity; I told him “Honestly I think supergravity is bullshit” he smiled and said “Yes, it pretty much is…”. He had a fantastically dry sense of humor (e.g. when giving [...]

General Covariance Generally Irrelevant In Quantum Gravity?

Just a few quotes from Misner, Thorne, and Wheeler’s Gravitation (I love that book…it’s my Bible):
“By ‘prior geometry’ one means any aspect of the geometry of spacetime that is fixed immutably, i.e., that cannot be changed by changing the distribution of gravitating sources.“
(Italics are Misner, Thorne, and Wheeler’s; bold is my emphasis; this is on [...]

Lubos Motl: What An Honor!

I know I said I’d take the day off because I have to write an essay, but there are times when I have the urge to write prolific amounts.
The cause of this post is that Lubos Motl, the prophet of Strings, has written a prolific post on his blog dealing with the fallacious premises that [...]

Graviton: The Particle that Never Was

I have started a little discussion on my about page and figured it be best to address the points made in a post dedicated to the heart of the matter: gravitons.
They are hypothetical massless particles that are the mediating boson of gravity…just like how photons are the mediating boson for electromagnetism. Intuitively, gravitons must be [...]

Random Incoherent Thoughts From a Sleep Deprived Physics-Major

First off, I suppose I should give a little note on why I’m writing about Carlip’s class. If you go to my about, you’ll find that I studied at the CalTech library independently with a retired rocket scientist (I never enrolled at CalTech, I only read the books they have on physics and math!). I’ve [...]
