Double degree in nanotech and applied science (however that applied science B.Sc is most likely gonna lead me on to a theoretical physics Ph.D.)[/QUOTE]
Sweet, I'm doing a maths/physics double degree, then I'll pick one to do for postgrad.
These two brilliant books by Brian Greene:

The main theme of this is String theory, but it explains both general and special relativity and quantum physics very well in the first half of the book. If you do not care much about string theory you can just stop before that part.

This isn't written specifically for quantum physics either, but it touches upon it many times in its attempt at to explain spacetime.

I would have loved to do that, but no such option at the uni I'm at.
Also, just remembered some graffiti I saw at the Uni bar's bathroom: "schrodinger's cat walks into a bar... and doesn't" hurr hurr

Damn, well nanotechnology is pretty interesting too, and I guess you can use any extra electives for maths stuff if there's a particular area you're interested in. After your phd, Have you thought about about where you would want to work?

I thought of doing a double Master degree (actually I'm still thinking about it). I'm definitely taking a Master in Industrial Nanotechnology, might take something else too (which would end up being either in the field of physics or economics).
Quantum Suicide is also an interesting topic:

[QUOTE=Block;30890618]It's explained really simply and weirdly. As far as I know, if two electrons are entangled, when you know the spin of one, you know the spin of the other as well.
I don't see how this is "information" though. It's like having two boxes and picking one box at random to put a coin in. Then you take the boxes really far away from each other. Open either box and you know what's inside the other as well.[/QUOTE]
The interesting part is when different persons read it at the same time.
[QUOTE=sltungle;30889185]I learned about quantum physics on my own when I was about... 14 or so. The stuff I learned for about 90% of my first semester at uni was stuff I already knew years ago, but towards the end of the semester we started to touch on new stuff I wasn't 100% familiar with.
When I was like 15 or 16 I tried clearing up some issues I was having with some concept with a physics teacher at my high school and he was 100% certain that electrons were physical, ball like particles particles (like marbles). But it seems he was wrong and I was right. If you treat them as particles and not waves they're point particles. No height, no width, no length... no volume. Yet... they're still there.
Of course when you treat them as waves that whole situation changes, though.[/QUOTE]
Wait, I think you're wrong, but I could be wrong (lol).
I think the way it works is that electrons are point particles but the probability of finding them within their orbit is determined by a wave of probability.

That's boring to listen to...
Don't disagree with me. The guy sounds like my grade 12 English teacher. Too monotone and taking too damn long to get the point across. Makes you want to get up and leave and come back in 10 minutes just as he's getting to the point.

That's when you consider it as a wave (as you just said). But if you treat the electron as a classical particle and not as a wave then, as an elementary particle with no substructure, it should have zero dimensions. No volume whatsoever.

This. A point charge. But then, in semiconductors we get introduced to wonderful things called holes, which is the absence of an electron in a place they might be and they have a "current" and it becomes even more of a mess.

Oh god. Don't remind me.
Fucking P-N Junctions.
That Dr Quantum thing about everything being entangled and what-not is just bullshit. If you want to learn about quantum physics, avoid the Dr Quantum videos.

[QUOTE=adamjon858;30886382]I don't really know much about quantum physics but I just watched a documentary on it and I really want to learn more about it.
I have taken a few upper college level physics classes but all of them were materialistic in nature. Just thought that there'd probably be a few people on Facepunch who knew a good place to start learning. Right now I'm just planning on Wikipedia but I'd prefer something a bit more visual (a movie would be good too). I'm just looking for whatever is the best place for Quantum Physics.[/QUOTE]
Got bad news for you, science is materialistic.

And a lot of my stuff as a technician...
It is pretty interesting sometimes.
Transistors suck ass.
And I bet they don't like me either, I've fried so many of them.
On a minorly related topic I remember once in physics in year 11 I wanted to see if I could turn one of the springs from a pen into a very tiny electromagnet by hooking it up to a small power supply.
Of course, being so tiny, even at a low voltage the damn thing burst into flames. Twas a bundle of laughs until my physics teacher could smell the burning...

100uf 24v electrolytic capacitors (Hint: you find them in old TV sets) incorrectly biased across the mains. Just aim it away from yourself.
I study Electrical Engineering I and I get all the math necessary to understand it more or less, such as differential equations, linear algebra, probability, physics, complex analysis, etc.
I wish I was into science, but I am absolutely terrible at math. I even suck at 8th grade algebra. It sometimes is hard for me to even remember how to count by any number other than 1,2, 5, and 10. I am not fucking kidding, when it comes to math my brain gives up. Math isn't even that fun anyways.

In my experience it's that kind of thinking which makes you bad at maths.
I remember I used to hate maths as a kid because I associated it with school, and I really didn't like school. My grades reflected that. I was doing really well in maths at first, then for a few years (as in like 4 or 5) I did terribly because I just wasn't paying attention. Then eventually I realised I really did love maths, I was always picking out mathematical patterns and relations in things, and I realised how useful a tool it was for explaining and understanding the universe. So I stopped associating it with something negative in my mind, started paying attention, and I literally went from getting a D or an E in one test in high school, to getting an A+ in the next one.
It wasn't even a gradual change. I went instantaneously from almost failing grades, to literally the top mark in the class.
I got a bit lazy in my last year of highschool though in one of my two maths classes and my mark dropped to like a C or a B (in the other class I think I was averaging As, though).
You've just gotta stop going, "oh, maths is hard, boohoo I can't do this," sit down for a couple of minutes and think about things and you'll realise it really isn't difficult at all.

I was fucking terrible at math and didn't enjoy it at all until I was about 16. Now it's one of the things I'm most interested in. And I have no idea why I got so good at it so quickly.
I see math as more of a tool, but the subject in itself can get quite interesting sometimes. It's physics that's the real beauty imo.

Same. Up to 17 I had the equivalent of F--- (we had marks from 1 to 10, 6 being sufficiency, and I had 3). Then at 17 shit turns around (also because I moved to Sweden, and school wasn't a prison camp anymore, making me a lot more interested and willing) and I get straight As, even though I barely studied at home (like, 1 hour a month max).
