Google the word “quantum” and take a look at what comes up.
In addition to the obvious news articles about the latest developments in the field and the Wikipedia entries on quantum mechanics, you’ll undoubtedly come across a heap of other, seemingly random, stories.
I found, for example, a David Bowie song being compared to a quantum wavefunction (by none other than British science popularizer Brian Cox), as well as a new cruise ship being named Quantum of the Seas. Then there’s the usual jumble of pseudo-scientific “wellness” therapies that misguidedly adopt the word in a strange attempt to give their treatments some sort of credibility.
So while it seems that everyone is talking about quantum something or other, how much do we really understand this notoriously difficult subject? More to the point, how much do science journalists, like me, really know about the subject? I write stories about quantum mechanics from time to time for Physics World and the subject can, I assure you, be fiendish and quite mind-bending.
