Fucking hate quantum mechanics. No offense but I'm too fucking lazy to be spending 12+ hours a day in the library EVERY day to just get a stupid fucking piece of paper. CHrist I'm burned out as a mother fucker. I'm going back to my math + cs degree. It's not like it's gonna make me any fucking money anyway. Man this shit fucking sucks so bad. I wish I could show you my homework right now, I *literally* wanna shoot myself in the fucking head.
 


AND MY TEACHER DOESN'T EXPLAIN ***SHIT*** WOW HE SUCKS SO FUCKING BAD - THIS IS COMING FROM A DUDE WITH A 3.85 GPA!!!!!!!!!!!!!!!!!!!!!!!!!!!

no, it is not hard. you just study bullshit easy theories that you will never apply so you only need a very shallow understanding of them.

That and

you've never taken a single quantum class in your life.

There's a reason that smart people aren't taking physics courses anymore. Quantum mechanics is inherently incomprehensible because it's both incomplete and unrealistic. You've got mathematical models that are veritably correct, but as of yet they are detached from any meaningful conception of physical reality. Even worse, you're going to have nonsense theories shoved down your throat at the same time. This is going to prevent people who would strive to improve the state of understanding from entering the field in the first place. And these aren't just my personal opinions... well-respected physicists believe that this is occurring, as well.

Ok, please answer this for me master:

What wavelength photon would be required to excite ground state hydrogenic Neon to the principle quantum number whose energy is equal to the ground state of hydrogen. (Ne 9+ <--<< this i know. E = 13.6 eV, this i also know). Where in the electromagnetic radiation spectrum does this photon lie?
 
FUCK I AM GOING TO DIE!!!!!!!!!!!!!! THIS SHIT SUCKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! SO BADDDDDDDDDD!!!!!!!!!!!!
 
Meh. After finishing my degree I got to the conclusion that that only thing good about university is meeting different people and point of views.

I started engineering but I honestly couldn't keep up with Calculus 3+ courses while still dedicating time to my then-ecommerce store. The physics and chemistry courses I did take where hella fun, but even then having my mind on business was funner and more enjoyable. So I switched up to marketing and finished it asap.

Point is: get your mind straight and STOP WHINING!!! Even more if it's about something that wont make you money or make you a better person.
 
Friend of mine finished his physics degree then went onto do a MSc in financial mathematics and is now interviewing with tier 1 banks, Goldman, JP Morgan and a couple private equity funds.

If that's what you want to do the financial rewards are there. He definitely sacrificed a lot to get top marks though, almost all his free time during exam months.
 
Just to walk you through the steps:

1. Calculate the energies of the two states.

2. Find the difference in energy. This is the required energy of your photon.

3. Use E=hf, where h is Planck's constant, f is the frequency of the photon, and E is the energy difference to find the frequency of the photon.

4. use \lambda f = c, where c is the speed of light, /lambda is the frequency, and f the frequency to find the wavelength.

5. Look it up on the EM spectrum to see what region it falls in.

You're done.

Also, it's quite possible your prof. spoon fed you some equations that would make this easier.

You'd make more with an equity stake in a growing, VC backed tech venture, than you'd make as a junior financial analyst. You'd also have a much more rewarding experience.

Everyone in finance is literally just "doing their time" to afford the life that they really want, if I was just getting out of school now I would of went in learning programming and had more fun moving out to Silicon Valley than Wall St.

[I may be biased/bored/jaded since I've made my first bit of money in finance and didn't have a fun time doing it.]

The reason that smart people aren't taking physics any more is because no appreciable progress has been made in theoretical physics for 30 years. The LHC doesn't count. They're just confirming a theory that was well established by the early 80's. It would have been interesting if they DIDN'T find the Higgs, but as it stands, it's just boring. It's hilarious watching them wave their arms to justify more funding.

QM is definitely very strange, but that's part of what makes it fun. We still don't understand what it means for physical reality, and there are plenty of people in the Foundations of Physics community who are trying to answer that question as we speak.

The biggest outstanding issue is the Measurement Problem, which still has not been solved. Each of the current solutions to the problem carries with it its own noxious conceptual difficulties: Measurement problem - Wikipedia, the free encyclopedia

Thank you for the walkthrough, I appreciate it. I actually figured it out earlier (n = 10), but it was definitely a pain. 2 more problems left on the test. The trickiest part by far was finding the original E for Ne 9+. I didn't know that it's simply the bohr radius divided by Z. Searched everywhere for that.

I used n = 10 to simply find the energy of the photon (non relativistic of course). Thanks again man! What did you major in?
