Heisenberg’s uncertainty principle

Heisenberg’s uncertainty principle is famous in quantum mechanics. However, it doesn’t have its roots in quantum mechanics. Let’s look at Fourier transform pairs. Continue reading Heisenberg’s uncertainty principle

Quantum entanglement: the EPR paradox and Bell’s Theorem

Einstein didn’t like that quantum entanglement seemed to imply information travelling faster than the speed of light. We discuss Bell’s Theorem. Continue reading Quantum entanglement: the EPR paradox and Bell’s Theorem

Quantum entanglement: non-locality and the state of a two-particle system

In this two-parter, we discuss quantum entanglement, non-locality, and some mathematics. In the next post, we discuss the EPR paradox and Bell’s Theorem. Continue reading Quantum entanglement: non-locality and the state of a two-particle system

This is not an atom

The standard cartoon of an atom is incorrect. An atom is not like a tiny planetary system. Quantum mechanics is all about the wave function. Let’s observe this carefully. Continue reading This is not an atom

A modern kitchen with a microwave oven. Is the radiation of a microwave oven unhealthy?
Physics, Secondary ed level, Tutorial

Is microwave oven radiation unhealthy?

We discuss what electromagnetic radiation is and why ionising radiation is dangerous. We discuss how a microwave oven heats up food, and vitamins too. Continue reading Is microwave oven radiation unhealthy?
