What is the hardest thing to understand in physics?

classical dynamics of spinning tops
The hardest thing that an undergraduate physics students must learn is the classical dynamics of spinning tops (also called “rigid bodies” in this context).

Why is quantum physics so hard to understand?

Systems with quantum behavior don’t follow the rules that we are used to, they are hard to see and hard to “feel”, can have controversial features, exist in several different states at the same time – and even change depending on whether they are observed or not. …

What is more difficult than quantum physics?

General Relativity is more mathematically difficult than non-relativistic quantum mechanics (which is what most people mean when they say “quantum mechanics”).

What is the hardest topic ever?

Let’s dive right in, and look at why these subjects are the hardest degree subjects.

• Chemistry. Chemistry is famous for being one of the hardest subjects ever, so it’s no surprise that a Chemistry degree is fiercely challenging.
• Medicine.
• Architecture.
• Physics.
• Biomedical Science.
• Law.
• Neuroscience.
• Astronomy.

Does anyone really understand quantum physics?

“I think I can safely say that nobody really understands quantum mechanics,” observed the physicist and Nobel laureate Richard Feynman. That’s not surprising, as far as it goes. Science makes progress by confronting our lack of understanding, and quantum mechanics has a reputation for being especially mysterious.

Is relativity or quantum harder?

If you look at a standard undergraduate physics curriculum, you will conclude that QM is much easier than GR. Classical mechanics, special relativity, and E&M make a reasonable first year; classical waves and QM fill a second year, but GR is a graduate-level or fourth-year course.

What is the most complex theory?

The quantum entanglement theory says that particles can influence each other even if they’re separated by great distances, like billions of miles or maybe the entire length of the universe.
