User:Theoretical wormhole

Hello people!!!

As my username suggests, my passion lies in physics, specifically theoretical physics and the (more or less rigorous) mathematics that is associated with physics. My favourite topic in physics is a toss-up between General Relativity and Lagrangian and Hamiltonian mechanics. Both are complex and mathematially vigorous, yet simple and beautiful.

My favorite equation in physics is the principle of least action (aka Hamilton's principle). This equation is given as:

$\delta S=0$

This equation is simple yet extremely powerful in physics. What I admire (even now) is that this simple equation can be applied to practically ANY domian in physics.

My second favouite equation in physics are the Einstein field equations from General Relativity.

$R_{\mu \nu }-{1 \over 2}g_{\mu \nu }\,R+g_{\mu \nu }\Lambda ={8\pi G \over c^{4}}T_{\mu \nu }$

They are my second favourite (rather than my favourite) ONLY because one can derive the EFE's from the Einstein–Hilbert action!

One `plague'/`confusion' in physics is conventions over signs. Some of my preferred choice of signs include the signiture $(-,+,+,+)$ as well as $g\equiv \det(g_{\mu \nu })$ having a weight of $-2$.

My preffered set of units are Planck units (aka natural units). Though I don't mind SI units;)

Lastly, my favourite theorem is Noether's theorem.

My objective is to get a PhD in physics!
