What parts of Physics are very difficult to comprehend?

jsprplc2006: What parts of Physics are very difficult to comprehend?
I’m curious what the hardest-to-understand areas of physics are. I’m in the second year of a physics degree, and I’m curious what might become difficult. I’ve been able to understand both special and general relativity. Later this year I’ll be learning quantum mechanics, particle physics, solid-state physics, and the Schrodinger equation.

Which of these topics am I most likely to struggle with (keeping in mind I already understand general relativity)?

I’m curious as to why people think you have to be really smart to study physics. Not to say I’m not, but I wonder.

just reading the terms “quantum mechanics”, “particle physics”, “solid-state physics”, and “Schrodinger equation” makes my brain hurt.

But my brother got his Ph.D. in solid-state physics.

well you sound like youre just on here to boost your already ample ego to me, I think its generally people who dont like maths who find Physics difficult but also people just find it deadly boring

QUANTUMMMMMMMMM PHYSICS.

people have to be smart enough to understand bcoz
1. d abstract complex theories n equations.
2. they must understand Higher Advanced Math to do physics.
3. n if u go deep inside physics its about understanding of Natural Phenomenon n why, how things happen n d reason behind things happen is not “common” to common senses , u have to work it out by using tools n math, not by ur eyes, nose, ears alone . n the theories u learn is not exactly absolute n can be wrong too, so wats is the truth u have to decide for ur own.
pretty tough compare to other subjects.

It depends upon your capacity to learn and unlearn. It appears every new theory in physics require unlearning of some previous theory.
