Usually I don't make such a fuss about things, but this is one of those monumental days. In the year 1900 Max Planck published a quantum hypothesis which led to the discovery of Planck's Constant. One substantial step towards our understanding of the quantum mechanics. The term Quantum Mechanics didn't actually come around however, until the mid 1920s.
Quantum Physics brought with is a slew of difficult and fascinatingly bizarre ideas that challenged our idea of normal mechanics. And what writer wouldn't be enthralled by such a powerful and mysterious look into the wonder of the universe? It became and is increasingly a popular term used in many science fiction stories and shows. Not always wisely and not always well. There are plenty of times when it seems a writer's default response to some implausible technology or outcome is simply to have a character drop the word 'Quantum' in front of something as though Quantum Physics were the magical word which made all bad science good.
Of course, when used wisely it can be a powerful tool to explore remarkable stories filled with potential and wonder. The other day I stumbled on this remarkable site: A sci-fi writer's guide to Quantum Physics. If you have a spare moment, take a look!
