Why don't things fall up?

 
Have you ever wondered why the sky is blue? Could you explain why ice cream melts? Have you forgotten why scientists think the universe started with a Big Bang, and do you understand the difference between respiration and breathing? 'Why Don't Things Fall Up?' will gently remind you of everything you may have learnt once upon a time, but have somehow forgotten along the way. If you've ever changed the subject when a child has asked for homework help, or if you have forgotten the basics of science - then this is the book for you. Using questions asked by children as a starting point, Alom Shaha takes us on a tour of the 'big ideas' of science from his unique perspective.
