Question

What is the quantum theory in simple terms?

Answer 1

1. Modern physics uses quantum theory as the theoretical foundation for explaining the nature and behavior of matter and energy at the atomic and subatomic levels.
2. Quantum theory is a branch of physics that investigates subatomic particles and their interactions.
3. It is founded on two equally important and fundamental ideas: that physical quantities, such as energy, are quantified, and thus cannot be emitted continuously, but rather in multiples of the smallest possible unit, the quanta.
4. The quantum theory states that the measurements we make on real systems are the results of a complex probability distribution.
