Aberystwyth University closed one of its campuses a few years ago. The place has been left to rot, but recently they’ve started clearing the place out, and removing all the old scientific textbooks. Most of them look untouched. Wonder how much this lot would have set students back if buying new.
Are you seriously trying to argue that an employer is going to like promote you because you're reading a physics textbook in your spare time?
I'd like to be on whatever drug you're taking that you think this that's how the world works. This is what is called 'delusional optimism'.
I studied advanced mathematics for fun, it in no way improve my job prospects, performance, or make me 'more intelligent'. It was just a personal fulfillment thing.
It's fine if you want to learn advanced topics in your spare time, I love that myself. But I'm no under no delusion it improves anything about my life. It's just a preference of how you like to spend your time.
anyway, by all means, please go buy 100 old text books and go to a homeless camp and try to educate folks about physics. see how that goes.
