Can you “add” colours? Relativity 5

You’ve probably learned early on that there are three primary colours. But why three? And why these three? And what does it have to do with “adding” colours? Is the “addition” of colours even an addition? Surprisingly, the answer lies in the beautiful mathematics of linear algebra and (high) dimension spaces!

History of planet discoveries | Relativity 2

Pluto has recently been demoted from its planetary status. With a bit of hindsight, what’s surprising about this demotion is not that Pluto is no longer a planet; it’s that it ever was regarded as a planet. And the reason for that lies in a nice piece of History.
