## Does anyone understand quantum physics?

Yet the weird thing is that no one actually understands quantum theory. The quote popularly attributed to physicist Richard Feynman is probably apocryphal, but still true: if you think you understand quantum mechanics, then you don’t.

### Who said no one understands quantum physics?

“I think I can safely say that nobody understands quantum mechanics.” It is one of the most repeated quotes of Richard Feynman (11 May 1918 – 15 February 1988), and is undoubtedly an unusual phrase coming from the mouth of a physicist.

**Why is quantum physics so hard to understand?**

Quantum mechanics is deemed the hardest part of physics. 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.

**Who said if you think you understand quantum mechanics?**

laureate Richard Feynman

Small wonder Nobel laureate Richard Feynman supposedly said: “If you think you understand quantum mechanics, you don’t understand quantum mechanics.”

## What is wrong with quantum mechanics?

The trouble is that in quantum mechanics the way that wave functions change with time is governed by an equation, the Schrödinger equation, that does not involve probabilities. It is just as deterministic as Newton’s equations of motion and gravitation.

### Who is the best quantum physicist?

Famous for: Quantum Theory of atoms The greatest physicist of the time, Max Plank is credited with the birth of quantum theory, which won him the Nobel Prize for Physics in 1918.

**What is the hardest physics problem?**

Quantum Gravity The biggest unsolved problem in fundamental physics is how gravity and the quantum will be made to coexist within the same theory.

**How long does it take to learn quantum physics?**

If you seek to become a quantum physicist, you have to complete four years of undergraduate training. You also can complete an additional two years of schooling to earn a master’s degree followed by five years of doctoral degree training.

## Who said anyone who is not shocked by quantum theory has not understood it ‘?

Anyone who is not shocked by quantum theory has not understood it. Heisenberg recounts a personal conversation he had with Pauli and Bohr in 1952 in which Bohr says, “Those who are not shocked when they first come across quantum theory cannot possibly have understood it.” Heisenberg, Werner, Physics and Beyond.

### What was Feynman’s IQ?

An IQ test administered in high school estimated his IQ at 125—high but “merely respectable”, according to biographer James Gleick.

**What is the hardest theory to understand?**

These are 10 of those theories, which are incredibly hard to understand.

- Simulacra and Simulations.
- The Dichotomy Paradox.
- Vasiliev Equations.
- Maxwell’s Equations.
- Gödel’s Incompleteness Theorem.
- The Theory of General Relativity.
- Quantum Mechanics.
- We Live on the Event Horizon of a Four Dimensional Black Hole.

**Can we get energy from nothing?**

No machine can create energy out of nothing, as this would violate the law of mass-energy conservation, which is fundamental and universal. The law of mass-energy conservation states that mass-energy can never be created or destroyed. It can only be redistributed throughout space and transformed into different states.
