Science with pictures

I have just started reading Stephen Hawking's "A Brief History of Time" again, (haha thanks to Spellcheck im not reading "A Brief History of Tim"!).

I say again because I started it a long time ago but got sidetracked as usual.

I'm on page 43 and so far learned about why feathers and lead weights fall at the same speed on the moon, and all about Future Light Cones, something that I bored Tobe silly with over lunch.

I have got hold of the latest copy of the book, which literally has big pictures to help explain everything!

While on the subject of Stephen Hawking, have you seen these hilarious pictures?!
