Who said if you think you understand quantum mechanics you don t?

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 the problem with quantum mechanics?

There are two problems. One is that quantum mechanics, as it is enshrined in textbooks, seems to require separate rules for how quantum objects behave when we’re not looking at them, and how they behave when they are being observed.

What did Richard Feynman do?

Richard Phillips Feynman (/ˈfaɪnmən/; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle …

What did Richard Feynman get the Nobel Prize for?

in Physics
Fifty years ago on October 21, 1965, Caltech’s Richard Feynman shared the Nobel Prize in Physics with Julian Schwinger and Sin-Itiro Tomonaga. The three independently brokered workable marriages between 20th-century quantum mechanics and 19th-century electromagnetic field theory.

Why was Feynman important?

Richard Feynman was a Nobel Prize-winning American physicist, particularly known for his contributions to quantum physics, quantum electrodynamics and particle physics, as well as quantum computing and nanotechnology. By his early youth, Feynman described himself as an “avowed atheist”.

What does quantum mean in simple terms?

Quantum is the Latin word for amount and, in modern understanding, means the smallest possible discrete unit of any physical property, such as energy or matter. Planck wrote a mathematical equation involving a figure to represent individual units of energy. He called the units quanta .

What are the basics of quantum mechanics?

Quantum mechanics is the foundation of chemistry, because it deals with subatomic particles, as well as atoms, molecules, elements, compounds, and much larger systems. At the sub-atomic scale, there is no boundary between particles and waves.

Did Richard Feynman win a Nobel Prize?

Richard Feynman won the Nobel Prize together with Sin-Itiro Tomonaga and Julian Schwinger “for their fundamental work in quantum electrodynamics (QED), with deep-ploughing consequences for the physics of elementary particles”.

Does quantum mechanics explain the universe?

Quantum mechanics is the body of scientific laws that describe the wacky behavior of photons, electrons and the other particles that make up the universe.

What is the theory of quantum mechanics used for?

Quantum theory is used to explain such phenomena as the photoelectric effect and the uncertainty principle. ♦ Another term for quantum theory is quantum mechanics, which also refers specifically to the use of quantum theory in studying the structure and behavior of atoms and molecules.
