| There are atoms and cells and things called bacteria. They are very very small and very very numerous. So we end up using really small and really big numbers to describe them. This unit asks you to imagine how many bacteria are on that bit of skin we mark out. And how very grateful we are that they are all there. The numbers for the sizes are very small, but few take the time to consider what they really mean. It takes a lot of imagination, so you are asked to express these ideas creatively in words and images. |
