QUANTUM PHYSICS

Schrödinger’s Cat is Alive and Well and Living in a Parallel Universe.

The Many Worlds Interpretation of Quantum Mechanics solves the mystery of the cat being both dead and alive: in one universe it is dead and in another it is alive.

Quantum Mechanics is strange.

Richard Feynman, the physicist and Nobel Laureate, once wrote,

“I think I can safely say that nobody understands Quantum Mechanics”

And I imagine he most included himself in that assessment.

Quantum Mechanics simply cannot be understood with our everyday experience of the physical world.

It’s a system where electrons behave like particles, or waves, or both. Or, indeed, neither. Analogies don’t fully work; electrons behave like electrons— they exhibit behaviour that is similar to a wave and behaviour that is particle-like.

Superposition

One of the strangest aspects of Quantum Mechanics is superposition, a situation where something can be in two different states at the same time and its definite state is not resolved until an observation is made. At least, that is one way of looking at it.
