Brian May of Queen fame was actually studying a PhD in Astrophysics before his music really took off. Queen became one of the greatest bands of all so Brian abandoned his studies to focus on the music. Fast forward to 2006 and he decides to finish the PhD he started many years ago.
In 2006 as he was getting into the swing of Astrophysics again, he released a book with sir Patrick Moore and Chris Lintott. This book essentially reviews the timeline of events from the formation of the universe to its potential end. It is rather basic in its approach and doesn’t talk of equations or any hard science. For someone who has no knowledge of this topic its a great introduction to cosmology but a little too basic for my tastes.
