This blog has been dormant for a while, mostly because the members were busy with many things, but let me break the ice once again. In the intervening two months, I have read a couple of non-fiction books, mostly based on science, and today I want to speak about one particular book that I enjoyed reading a lot. The book is called 'what if?' with the tag line 'Serious Scientific Answers to Absurd Hypothetical Questions' by Randall Munroe, the creator of the highly successful webcomic xkcd.
