In the same Singh article in the Guardian that I mentioned in the previous post, there is a quiz. Nice to see. I’m not really sure what its purpose is, but it does not have to have one. Why not have a go at it yourself?

It is entitled “Do you know your Newton from your neutrons?”:

6. If the Sun were to disappear right now, how long would it be before we noticed?
