The Astronomy book is $9.99 through the Australian iTunes website - the downloadable pdf version from Bojan's link is free.

I've downloaded the free version and will have a bit of a browse during the school holidays.

Thank you Bojan for sharing the link.

PS I've also downloaded the four Physics texts to have a look at!

Thanks Bojan. That is what I like to see. Peer reviewed papers by scientists..
