hello people. well, i'm pretty sure it's not the best place to discuss about this, but what the fuck, it's still a forum.. i'm lately into quantum physics, this thing just got stuck into my head and im watching documentaries and stuff. still a dummy though. i find it really amazing even if i dont understand most of the things they say there haha

what do u guys think?

My favorite quote about quantum mechanics is by Niels Bohr: "Anyone who is not shocked by quantum theory has not understood it".

Also, the universe is made of 12 particles of matter, 4 forces of nature.

this quote is SO true :p even if you understand like 1% of quantum theory you will be shocked

Quantum theory is only shocking to those who misunderstand the nature of things to begin with. If your perspective is already aligned with it, it's not shocking at all.

I hate quantum physics... Too hard for me, nuclear physics is so much simpler ;D

Careful there - you don't know until you observe it directly ;)

Try to go here http://www.physicsforums.com/index.php a wide arrangement of topics of all kind of matters. Im a regular visitor there myself.

I don't want to study it as my job, but I'm really interested in it.

I've read up a bit about it because I find it interesting and it is shocking indeed. The funniest thing to grasp so far ( although I understand it happens) is the electrons through holes thing..Where they only decide whether they have passed from hole A or hole B after they have passed through and only if you decide to check through which hole they passed.
Quantum physics.. Biggest troll in the universe?

If you are really into quantum physics here's the bookthat we use.
Warning! High exposure to quantum physics may result in death if your mind is not prepared.

It's a lot of fun to read! :) I think in the first edition someone (forget who) called Feynman half genius and half buffoon, but later changed it to all genius and all buffoon. :)

Yes.

I think quantum physics is fascinating too, but it's not the full picture. Astrophysics is where all the action is. Astrophysics with an incorporation of the understanding of quantum mechanics can and does eventually lead us back to greater understanding of the small by looking at the large. It's very exciting.

This was my first exposure to it and 5 years later I actually understand it a lot more.

I personally dislike quantum physics with a passion because of the astounding confirmation bias it brings out in people dabbling in or observing it from the fringe. It's the one field of science that attracts the greatest number of crackpots that bypass the most vital aspect of the scientific method : relying on observation, and assuming/testing the most grounded/simple hypothesis first. I know that this field of study is far more than just time travel, but I have a special place reserved in my facepalm gland for the number of time travel enthusiasts that gather around it and bark about how stupid everyone else is if they don't 'believe' in it.

It just irks me how when some experiments yield tiny bits of interesting data, people immediately begin flapping their arms and yelling "PHYSICAL MOMENTUM CREATES DISTORTED PASSAGE OF TIME" instead of first considering more grounded alternatives. Occams Razor is far from infallible and often used poorly, but it's a great starting point when provided with a range of hypothesis to pursue.

Back when quantum theory was relatively new, I thought they were on the right track but were missing the forest for the trees. Years later, after they've developed it a bit more, I think they're "getting there." They're still missing some important "puzzle pieces" in their observations and theories, but at least they're beginning to understand which pieces those are.

A Modern Approach to Quantum Mechanic by John S. Townsend is the way that I and pretty much everyone I know learned (some) it. Protip: actually do the example problems. You will think you understand (like me), but until you prove that you understand how to do them, you won't.
http://www.amazon.com/A-Modern-Approach-Quantum-Mechanics/dp/1891389130

Edit: oh yeah, and unless you have a strong foundation in Linear Algebra (when I say eigenvector, a visualization pops up in your mind), and experience with multivariable calculus, you can forget truly understanding anything.

I read a bit about quantum physics once. It's rather interesting, and opens up very strange concepts and strange possiblitities, mainly in computing, but I only sort of understand.

Yay, superpositions
