Where to Begin: Resources for Understanding Quantum Physics

In summary, In order to understand Quantum Physics, one must first have a good understanding of Linear Algebra and the other fundamental theories of Physics. Additionally, one must be able to measure and calculate probabilities at the quantum level. Finally, one must be able to understand the fundamental forces of nature through quantum field theory.

I'm sure you all see threads like this often, but I'm just getting started with understanding Quantum physics in general. I know how broad that statement is, however as you can tell, I don't know how to specify due to my lack of knowledge on the subject. When you all first started your studies, what textbooks did you use to start? Can anyone link me online papers and/or textbooks of which I can buy? I've been reading threads, however I don't understand a lot of the content due to my lack of knowledge. Where did you all start, can anyone outline the basics of Quantum Physics for me, and possibly link work to learn from? Thank you, and pardon my ignorance in the subject.

How serious do you want your treatment of quantum mechanics to be?

Popular science level? University level?

If the latter, what is your math and physics background?

I wanted to proceed to a popular science level at this point. I'm attempting to sustain enough information in order to soon help me enter a particular school in my area. Although not mandatory, I wanted to try to learn more (whereas I'm not skilled in the subject at all, obviously) for the sake of interest and through communications I'm having with the school, e.t.c. It's a bit complicated.
Anyway, I want to attempt to reach at least a popular science level for now, however I will most likely end up taking it farther assuming I get into the school. Thank you for the books, Stevie. I'll order them right away. :)

Have you taken (or do you understand) linear algebra?

Nobody 'understands' quantum physics. Its the science version of magic. You learn the concepts then misapply them to arrive at illogical conclusions.

I wouldn't go that far. The conclusions you reach are perfectly logical within the framework of the theory.

Honestly, with all of physics I don't think anyone understands it if you look deep enough. You can be an expert in a theory, and know exactly how to apply it to solve problems, but at the end of the day you can never quite put into words what it all means. That's part of the wonder/tragedy of being human - that we've been able to do so much by mostly fumbling around in the dark.

I'm also trying to understand quantum physics and all of physics on my own. Some things I learned so far: quantum is one of the most fundamental theories of physics. Physicists say it is more fundamental than classical mechanics (e/m, dynamics, optics, even atomic physics). It explains what happens to things at extremely small sizes and very low temperature/ energy. Everything is probabilistic at that realm. You can't say anything for sure about something unless you measure it. You can only have one aspect of it certain at a time. Like you can only know the velocity or the position. Energy occurs in packets that can't be divided called quanta (hence quantum mechanics). Quantum physics is used to explain the fundamental forces of nature through quantum field theory . Only force not explained yet is gravity although I remember physics teach telling me gravity isn't a real force.

:smile: That is the most honest statement I have seen and I am in full agreement.

Yes, I understand linear algebra.

And I think the ideal that Quantum Physics being something that you don't necessarily 'understand' is interesting. Although I clearly know nothing about the subject, there must be some form of understanding everyone has on the subject, or there would be no content to work off of...Other than that, that statement is pretty helpful. :)

Delong, that summary was incredibly helpful. Definently gives me a good concrete base, although some of the information I already knew. :) Thanks.

glad I could help somewhat.

Khan academy helped me with the math of QM. You can only truly understand QM when you get the math.
 
  • #15
Also you can learn QM both mathematically and intuitively from the Stanford YouTube series

Thanks a bunch. :) For some more background, I'm using the MIT Opencourse stuff in other subjects so that I can work up to the level a little bit better. I did find that a lot of the stuff there is below me, but I can definintely dig through what I know. Thanks for the further information, I'll check out the series right away. :)
 

FAQ: Where to Begin: Resources for Understanding Quantum Physics

What is Quantum Physics?

Quantum physics is the branch of physics that studies the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. It describes the fundamental principles and laws that govern the behavior of particles and their interactions with each other.

What are the key concepts in Quantum Physics?

The key concepts in quantum physics include wave-particle duality, uncertainty principle, superposition, and entanglement. These concepts explain the strange behaviors observed in the quantum world, such as particles existing in multiple states at the same time and particles being connected over large distances.

How does Quantum Physics differ from Classical Physics?

Quantum physics differs from classical physics in that it describes the behavior of particles at the subatomic level, while classical physics explains the behavior of larger objects. Quantum physics also includes probabilistic concepts, where the exact position and momentum of a particle cannot be known at the same time, unlike classical physics which is based on deterministic principles.

Why is Quantum Physics important?

Quantum physics is important because it has led to significant technological advancements, such as transistors, lasers, and computers. It also helps us understand the fundamental nature of the universe and has led to groundbreaking theories, such as the theory of relativity and the standard model of particle physics.

Is it possible to fully understand Quantum Physics?

As with any scientific field, our understanding of quantum physics is constantly evolving. While we have made significant progress in understanding the principles and laws that govern the quantum world, there is still much more to be discovered. It is possible that we may never fully understand all aspects of quantum physics, but we continue to strive towards a better understanding through research and experimentation.
