The Road to Reality: A Complete Guide to the Laws of the Universe by Sir Roger Penrose, who is also the Nobel Prize winner in physics in 2020, is a must read for all who are interested in learning about our physical universe and the mathematical laws underlying it. Sir Penrose gives a vivid description from the sub-atomic particles & their behavior to the more massive bodies in space.
The Road to Reality attempts to find common grounds & compatibility of the two grand classic theories of modern physics–Einstein’s general theory of relativity & the theories of quantum physics, covering aspects & possibilities of of the String Theory as well.
I felt this book is incomplete by itself – it opens up various opportunities to look into the future & lays out broad scope of where the research should be headed to understand our universe a little better.
