Science was FOUNDED on danger.
Let's try and break apart every fucking particle we can! Fuck mass-energy equivalence, I'm sure we can contain it!
[QUOTE=adamjon858;30888451]I really am behind/ahead on my Physics/Math. I took Calculus III and upper level physics classes at a college while I was still in high school and haven't taken any classes in the last 3 years at college because I tested out of them. Therefore, I remember learning a lot of the shit you mentioned but it's all vaguely familiar and I'll need some practice with it for it to come back.[/QUOTE]
When you are familiar with that, go on for a good college/university book about theoretical quantum mechanics. IMHO, it's better to visit lectures to learn it but that way also works.

[QUOTE=metallics;30889289]Whilst that's impressive, you don't need all that background, I think it depends what exactly you're interested in when it comes to QM. I came across wave-particle duality and the uncertainty principle at A level and quantum wells and band gap structures, tunneling and other quantum phenomena related to semi-conductor materials in my first year of university, with none of that background.
[/quote]
Particle-Wave duality can be shown by experiments, yes. Not much to understand there, just accept. But to understand the behaviours of the wave-nature you NEED to know the math behind it. Same for uncertainty principle, which directly results from the Fourier-transformation. Also quantum wells and band gap structures are different, since one is just a potential/barrier and the other one an energy difference between two bands (= "very close" energy-levels emerging e.g. from lattices).
Sure, you can "understand" band gaps etc. But to really understand why and how they origin, you need that background.

bipolar one suck, yes. Too much you have to do until they work linear like current-feedback, biasing etc. I like unipolar one much more (FETs)
[QUOTE=aVoN;30913350]Text[/QUOTE]
I agree you need the maths, but I don't agree you need to do the modules in such a structured manner if you're doing it for interest. Everything I've done like that for interests sake I've learned the bare minimum of maths to go with it as I go along. Which was my original point, I just meandered and didn't think it through fully or explain it well.

Yeah, something about being hit by the casing and some other nonsense about vapourised electrolyte being bad for you or something. It's all tosh, they just want to stop you having fun.
[QUOTE=sltungle;30908002]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.[/QUOTE]
I try, they put me in special ed math or whatever, it's still hard to concentrate on numbers and I don't have that I can't do this attitude. The school is making me feel like it though.
[QUOTE=JohnnyMo1;30909455]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.[/QUOTE]
I'm the opposite. I was baller at math until I got to college...then I stopped caring. The science applications to me were way more interesting.
Fuck everything!
Just imagine how many times you can halve something.
Infinity = proven.

As if! You don't even need drugs if you think about that enough.
Watching "Morgan Freeman's Through the Wormhole".
What do you guys think about that show? A lot of it is unproven theory but it's interesting to think about.
fuck this thread
[QUOTE=Radman;30892465]Quantum Suicide is also an interesting topic:

The concept of Quantum Suicide completely blows my mind. That Third Contact movie looks interesting as well, it's supposed to pertain to how quantum physics affects the universe and how people observing its nature creates ripples in spacetime.

Quantum suicide is an interesting idea, but I don't see any real reason it would be true. I didn't experience the world before I was born, so what evidence is there to suggest that consciousness can't end? And that movie looks like it will be silly quantum mysticism.
I hate it when people assert that consciousness is some INCREDIBLE FUNDAMENTAL CREATOR OF REALITY or some shit. That's not what the observer effect is at all. It's about measurement, not consciousness observation. In order to measure the state of a particle, you have to interfere with it via a photon interaction and that alters the system.

The Quantum Zeno Effect has a couple of potential philosophical ramifications. Conciousness causes collapse interpretation too (which is funny 'cause they both basically state opposite things).
You can find some decent Quantum Physics lectures on iTunes U

No body here is a scientist. Some may have knowledge of other theories, but by now most theories have already been thought up on this subject so you're asking people to tell you what they know about something someone else taught them.
Basically either get a class that'll teach you, or look up online (not as reliable).
So how old are all of you? I'm 16 at the moment, birthday was three months ago, and I'm only taking college algebra (about 15% of the way through my summer session), and will be entering 11th grade with physics honors as my science class. But I don't know any of what you guys are talking about at all. D:

It's something I like to call selective education. Where basically each school, despite being a part of the same school board, may teach things in a different order and in different ways. I'm 21 and there are a lot of things I don't know because my schools never taught me them or because I chose not to take those classes. So I more or less rely on the internet and discussions involving certain things. Oddly enough I have learned more from my computer than I ever had from any of my teachers.
20, at university, studying Electronic Engineering. Even in Electronics there is no escape from QM :(

But QM rules!
Dr Quantum must get all the pussy
Seems that my Nanotech Uni course has a healthy serving of Quantum Physics too, which is good because it's interesting as fuck.
I did basic quantum mechanics in my last year of school. Can't remember much - except that it introduced me to the Heisenberg uncertainty principle - which introduced me into quantum computing and qubits. All in all fun stuff.
Would those stanford lectures be good? I was 30 minutes into it and was understanding it, but I was getting tired so I went to sleep. And now I'm at my grandmother's house.
