I'm currently a student of physics at the University of Heidelberg.

My interests lie in theoretical physics of all kinds, and currently I am most fluent in gauge theory. I'm particularly interested in most forms of QFT.

My profile picture is obviously not of me, but if you know where it is from, you're awesome.

Having all the answers just means that you've been asking boring questions.

comment Is there really such a thing as a left-chiral particle?
Who says we do talk about left-chiral electrons/positrons in a technical, non hand-wavy sense? The chiral interaction in the Lagrangian is with the left/right-chiral part of the fermion field, not with particles!

comment About the perception of the flowing of time
"If time is continuous why would the perception of time being continuous or flowing be an illusion?" - Who says it is an illusion? In what context?

comment If you are not given a metric, which one is more fundamental: a vector or a covector?
Any account of differential geometry will do. I also show the definition of (co)tangent spaces in my answer here.

comment If you are not given a metric, which one is more fundamental: a vector or a covector?
Though physicists will oddly insist that this is a definition, it is not. Vectors and covectors are members of the (co)tangent spaces, which are at every point the space spanned by the $\partial_{x_i}$ (tangent space) and its dual. The transformation law follows from the definition, but it is not a definition by itself.

comment If you are not given a metric, which one is more fundamental: a vector or a covector?
Vectors and covectors both exist on arbitrary manifolds. None depends on the existence of a metric.
