The book I needed 6 months ago!
on 29 May 2017
I looked at this a few months ago and then didn't buy for some reason. With just over a week to go to an Open University End of Module exam, I buy it and now regret not getting this earlier. The first chapter alone was worth the cost as I now understand why ratios are used so much and how to manipulate them as well as using units and getting them correct first time. The book also has a great online facility with all the examples and questions in the book fully work out as well as great video tutorials. It doesn't go into all aspects of astronomy of course, but what it does cover is very well explained... Oh, how I wish I had got this months ago!!!!
