If you think PhD's are 100% accessible, I have to pay €3500 to travel to my own PhD defence, host a post-defence reception, host a dinner, and host an open bar party. All of this is customary in the Netherlands, which is absurd.

I learned to code because at the beginning of my PhD my supervisor asked me to model something and I was too scared to say I didn't know how, so I learned the basics of Python and MATLAB over a weekend and had results by the Monday.

As a former physics major and current physics postdoc, I almost failed computational physics at age 20, now I code on a daily basis. I used to cry over fractions, now I love derivatives and linear algebra. I used to hate experiments, now you can't get me out of the lab.

@lordofgummies33 I hate to say it, but as a former physics major, if you actually want to go into physics you should be the kind of person who finds this level of material completely obvious at 9 years old. It's absolutely worth studying -- but physics only needs people who are math freaks.

Poor take. My supervisor is an incredible person and I'm pleased to have a good relationship with him. While I'd never refer to him as my "parent" he's certainly more than "just" a boss. It's absolutely possible and healthy to have a relationship beyond "student/supervisor".

Your PhD advisor is not your "family", "parent", or "friend". They're a work supervisor. You're there to get a PhD from the university by providing research labor in a field of choice, which your supervisor oversees. It's a temporary contract. Don't lose yourself in it.

I've been trying not to fall outwith the actual science of LK-99, however I saw a comment which irked me. Someone was disappointed in academics for being pessimistic about LK-99. Let's get this straight, we WANT room temperature superconductivity.

With regards to LK-99 I have a few problems with the resistivity. 1. Resistivity shouldn't have a current dependence. 2. Two samples have a resistivity with 2 orders of magnitude difference but the same Tc. This isn't possible in BCS theory.

Sure! We are doing Angle-Resolved Photoemission Spectroscopy (ARPES). We excite electrons by firing light at a sample, we then measure the kinetic energy and angle of emitted electrons which allows us to map out the energy and momentum of the electron BEFORE it was excited.
