What did Einstein say about quantum physics?

What did Einstein say about quantum physics?

Einstein was the first physicist to say that Planck's discovery of the quantum (h) would require a rewriting of the laws of physics. To support his point, in 1905 he proposed that light sometimes acts as a particle which he called a light quantum (see photon and wave–particle duality).

Is it possible to understand quantum mechanics?

Quantum mechanics must be one of the most successful theories in science. … 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.

What is the quantum theory in simple terms?

Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level. … Planck wrote a mathematical equation involving a figure to represent these individual units of energy, which he called quanta.

What are the 4 quantum mechanics?

Broadly speaking, quantum mechanics incorporates four classes of phenomena for which classical physics cannot account: quantization of certain physical properties. quantum entanglement. principle of uncertainty. wave–particle duality.
