What is quantum theory?

The posts in this blog explain the main concepts of quantum theory without expecting you to have any understanding of physics or maths. Each post will just take a few minutes to read.

Quantum theory (aka quantum physics or quantum mechanics)  explains and predicts the interactions between the tiny particles that make up the universe. Quantum theory has become controversial because it shows that reality is weird and unpredictable.

The underlying ideas of quantum theory were conceived early in the 20th Century. The older ideas they displaced are called  'classical physics'.

Quantum theory provides an extremely accurate model of many physical effects, but it is famously enigmatic because physicists can't agree what it really means, even though they have been trying for a hundred years.
