Yang–Mills and Mass Gap]]>

The orbit earth at speed of light example confuses me. I've hear this for along time, A man launches in a spaceship and orbits earth near the speed of light for an hour, when he lands again, everyone has...

Abstract:

The second law permits the prediction of the direction of natural processes, thus defining a thermodynamic arrow of time. However, standard thermodynamics presupposes the absence of initial correlations between interacting systems. We here experimentally demonstrate the reversal of the arrow of time for two initially quantum correlated spins-1/2,...

From what i understand when we measure gravity its between 2 masses?

My question is asking if their is a gravity exertion to mass ratio?]]>

Anyways, the takeaway from lecture 2 is that curvature is an obstruction to finding a flat metric, or rather to finding a way to define distances between points which requires only Pythagoras. That is, (being able to define) a 'surface' which can have coordinates defined on it which are rectilinear.

The other...

I wonder if someone who is good at LaTex could write a short tutorial of the basics, with some common SciForums examples? I'll write one up myself, but I'm a complete beginner at LaTex so it will take a little while.

In the meantime,...

Matter to me is very much different . While frequences of the electromagnetic spectrum are inbedded IN matter , light itself cannot on its own , form matter , or an atom .

Perhaps I'm wrong , but if I am , how so .]]>

The above is unlike many other subjects. Flunk an early course in ancient history due to immaturity or failure to pay attention & it will not keep you from passing a later course in European or American history. similarly for various other disciplines.

Flunk an early mathematics course & you will probably flunk or have serious problems with later math courses.
