Welcome to this new general, where we discuss science careers including PhD, postdoc and the escape from academia to industry. This grew out from an earlier thread: >>12207909

If this goes well we'll get some pastas going, hopefully also a Wiki too. I was insanely naive when I did my PhD in Physics and with all the glossy info it can still be hard to find the brutal truth.

So let's have a comfy general, and also enjoy some relevant comics:

You might add some Feynman to this, his Cargo Cult Science article and his Appendix F. Also scientists should read these. For nature cannot be fooled.

Why is it that compressing a file already compressed by LZH can't compress it further?
Like if you gzip a .gz file you don't get any savings.
It seems like you could use a pseudorandom but reproducible (by using the same seed) perturbation.
Then compress the perturbed file, and repeat.
To decompress, perform LZH decompression and then reverse the perturbation.

This is an obvious strategy, so there must be some reason why it hasn't already been implemented.

High temperature superconductivity.

High Tc is part of solid state physics so not all is lost. Solid state is probably the safest choice career wise since it gives you a good chance in industry.

While I no longer do research I do follow the news and I am deeply concerned how rotten things are in academia. If you do a theoretical study in an obscure field you will have limited opportunities for employment - and your professor will know this better the you.

here's one that somebody put up on a wall in one of the the department hallways
