for example, I understand all string theory research papers; I understand all articles in high-energy physics. I'm fine with it. but I'am not too good at analysis. Can I be pure mathematician? or continue study theoretical physics ?

have a nice day. I was torn between mathematics and physics. I do not know which one I wanted. How can I decide? for me; theoretical physics, applied mathematics - topology (dif.topology, alg.topology, geom.topology), differential geometry easy than pure, proof based mathemics. I'm better...

How many pages of math can you absorb in one day? There was such an thread but closed. Thanks.

Thank you for comments :)

Hi; I study mathematics/theoretical physics. I learn a lot of stuff (advanced math/physics theory); but after few month; feeling like I forget everything I learn. Why? for example; I am working 7/24 mathematics (in academic year); after I am resting in the summer. I do not read anything in the...

twistor theory. also Ed Witten found a relationship between twistor geometry and string theory. https://arxiv.org/abs/hep-th/0312171 Nathan Berkovitz is best researchers in this field.

by the momentum of a particle we can mean the vector p=∂L/∂v, p=mv/√1-v^2/c^2, for small velocities this expression goes over into the classical p=mv. for v=c the momentum becomes infinite. after dp/dt=m/√1-v^2/c^2×dv/dt, if the velocity changes only in magnitude, that is, if the force is...

I love the soviet books and education. math books are fabulous. We say that the Russian language: Советская литература http://nozdr.ru/biblio/edu/fizika - You can read them all here.

http://nozdr.ru/biblio/kolxo3 ~ See this site. 25509 math and 14016 physics books,articles are available. (free) http://nozdr.ru/biblio/kolxo3/m - mathematics, http://nozdr.ru/biblio/kolxo3/p - physics.

Use vdisk.weibo. You can free download any book on this site.. There are 1000+ books on my computer. You can download all the mathematics and physics series.

Peter Petersen ~ Riemannian geometry, curvature chapter (grad texts in math) : ** First, we can measure the change in X by asking whether or not X is a gradient field. If iXg = θX is the 1-form dual to X, i.e., (iXg) (Y ) = g (X, Y ), then we know that X is locally the gradient of a function if...

if you're good at math, you know to read landau series. or feynman lecture notes can be a good choice.

hi. I read these books. I recommend reading: göckeler, schücker - differential geometry gauge theories and gravity, raifertaigh - group structure of Gauge theory, nash - differential topology and qft, atiyah - geometry of yang-mills fields, clay math.monograph - mirror symmetry, morita -...

have a nice day. You do not need a high IQ for research in mathematics. You know to start learning with simple books.
