Synopsis
Scientists are curious. Since ancient times, they have been asking and answering questions about the world around them. Scientists are also very suspicious of the answers they get. They carefully collect evidence and test their answers many times before accepting an idea as correct. In this book you will see how scientific knowledge keeps growing and changing as scientists ask new questions and rethink what was known before.
