26 Facts About Quantum Physics

What is Quantum Physics?

Quantum physics, also known as quantum mechanics, is a branch of science that deals with the behavior of particles at the atomic and subatomic levels. It challenges our classical understanding of the universe and introduces concepts that seem strange and counterintuitive.

1. Quantum physics explains the behavior of particles smaller than atoms, like electrons and photons.

2. It was developed in the early 20th century by scientists like Max Planck and Albert Einstein.

3. Quantum mechanics is essential for understanding the structure of atoms and molecules.

Key Principles of Quantum Physics

Several fundamental principles form the backbone of quantum mechanics. These principles often defy our everyday experiences and require a shift in how we think about the world.

4. Wave-Particle Duality: Particles can exhibit properties of both waves and particles.

5. Superposition: A particle can exist in multiple states at once until it is observed.

6. Entanglement: Particles can become linked and instantly affect each other, regardless of distance.

Quantum Physics in Technology

Quantum physics isn't just theoretical; it has practical applications that impact our daily lives. Many modern technologies rely on principles of quantum mechanics.

7. Transistors: The building blocks of modern electronics, including computers and smartphones, rely on quantum mechanics.
