Ever wonder how much gas carrying an extra penny in your vehicle’s coin tray uses up? How much food cows would require if they could photosynthesize? How about how long the sun would last if a giant water hose was spraying on it?
Well, you need to check out What If?, a site ‘answering your hypothetical questions with physics’ by Randall Munroe, creator of the brilliant webcomic xkcd. Munroe does a great job answering the above questions and more using a combination of humour, drawings, diagrams and a boat-load of math.
If you need a little break this Friday, I highly recommend you check it out!
