Lightning often strikes twice in the same place, the North Star is not the brightest star in the sky, and sugar does not make children hyperactive. Be ready to change your beliefs about what you think you know about science! You may already know that lightning, contrary to popular belief, often strikes the same place more than once. But this is just the tip of the iceberg that many of us mistakenly believe
about the world around us. Whether it's rumors, internet myths, or misremembered facts from your school days, misconceptions about science are frequent. We will focus on the fifty most common scientific misconceptions and explain the actual science and theories that debunk these popular myths, from the fear of the exponential population growth of humanity to the misconception that all humans are descended from chimpanzees or gorillas. This is a book for those who want to distinguish scientific fact from fiction.
