For example, he describes the notion of gravity and relativity in the following way: Imagine a thin mattress which is held outstretched. He explains a rather mathematical and theoretical idea with various illustrations and relatable examples.
Albert Einstein and the theory of general relativity was the highlight of the book. Hawking has a quirky sense of humour and along with ideas being developed also shares various life events of scientists. The book was addictive despite being a slightly difficult read as, once you understand an idea, you want to understand how it relates to other topics of the book.
The book uses minimal technical jargon and mathematical knowledge to explain how the notions of gravity, relativity, black holes have developed over the twentieth century. A Brief History of Time is an introduction to cosmology aimed at the layman and addresses fundamental questions such as “How did the world come to be?” and “Will it come to an end?”.
