I would like to welcome eminent scientist and author Marcus Chown to the Teen Librarian site.
For the two or three people who are not too sure who he is, here is a brief biography (and photograph in case you meet him in your Library).
Although Marcus’s wife is a nurse and does a very socially useful job, Marcus tends to write about things that are of absolutely no use to man or beast! Can time run backwards? Are there an infinity of universes playing out all possible histories? Was our Universe made as a DIY experiment by extraterrestrials in another universe?
There will be more from Marcus going online at various times throughout the day so be sure to check back later!
