Some of you will have seen that Alfie went to his school’s World Book Day celebration as Professor Astro Cat. For those of you not familiar with the Prof, he’s a feline scientist devised by Dr Dominic Walliman and illustrator Ben Newman, whose first outing, Frontiers of Space, is one of my favourite children’s fact books ever. Now he’s back with Professor Astro Cat’s Atomic Adventure (Flying Eye Books, RRP £15.99), a crash course in physics for children (and rusty grown-ups – I’ve been refamiliarising myself with the periodic table). The book aims to answer questions like, ‘Why is the sky blue?’ and ‘How does a car move?’ by exploring concepts such as light and motion, plus you’ll find pages on light, sound, gravity and even nuclear and particle physics. Everything is explained in a clear, entertaining way and the vibrant images, featuring the professor demonstrating the ideas at work certainly help with understanding. Alfie, nearly seven, has barely put his copy down and we’ve been treated to lots of physics facts. An excellent addition to any child’s bookshelf.
