15 Million Degrees: A Journey to the Centre of the Sun by Lucie Green

I have just started reading "15 Million Degrees: A Journey to the Centre of the Sun" by physicist, writer and broadcaster Lucie Green. So far I have found it very readable and technical bits are very well explained. It has a very good primer on what light is and how it works on us.

The Martian

I watched the DVD of 'The Martian' today and as both an astronomy and science buff I was quite impressed with the attention to detail on the science part. However the plot was rather lacking but the acting skills of Matt Damon and Jessica Chastain made up for it. In summary it is about NASA astronaut Mark Watney (Damon) being marooned on Mars after the rest of his crew mates had presumed him dead and had to make an emergency departure from the red planet.  Reminiscent of other solo survival stories such as Robinson Crusoe and Castaway, he had to survive physically and mentally.  Yes he does grow his own spuds using Mars dust and human excrement for fertilizer.  However things go awry when he somehow blows up his Mars "house" which doubles as accommodation and potato greenhouse.  The rest of the story just drifts on from that. One scientific anomaly is Watney walking normally in a non-weighted spacesuit on a planet with 38% of Earth's gravity.  I think some scientific liberties were taken there.  All in all a reasonable film for the science buffs but don't expect a great storyline.

Finished Bang! The complete history of the universe

In the past few days I have finished reading 'Bang! The complete history of the universe' by Patrick Moore and Chris Lintott.

This book is a very good introduction to the history of the universe from the moment of the big bang, past the present and onto the future of the solar system and indeed of the universe.  It introduces the sub-atomic particle particle physics side in a very easy to read and informative manner.

I thoroughly recommend this for anyone who wants to grasp the basics of the big bang and how the universe will progress in billions of years time.
