All things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another.

If, in some cataclysm, all scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis that all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another.

We find that the behavior of nature is very much like the behavior of particles.

The electron is a particle, but it's also a wave. It's both.

Probability is the mathematical language of uncertainty.

The heart of the mystery is in the double-slit experiment.

In quantum mechanics, the rules are different.

Symmetry is a fundamental concept in physics.

Conservation laws are the backbone of physics.

Gravity is a curvature of space-time.

Electromagnetism is the force that holds atoms together.

The weak force is responsible for beta decay.

The strong force binds the nucleus.

Particles have spin, charge, and mass.

The uncertainty principle is fundamental to quantum mechanics.

Wave functions describe probabilities.

Entanglement is spooky action at a distance.

Superposition allows particles to be in multiple states.

Measurement collapses the wave function.

Quantum field theory is the marriage of quantum mechanics and relativity.
