Science is based on the proposition that the world is as it is because of the laws of nature. In order to understand these laws, scientists must use illustrations to help them visualize how things work. This process is called “scientific illustration.” One of the most famous illustrations in science is that of a scientist’s microscope. A microscope allows scientists to see inside objects that they would not be able to see with their naked eyes. This illustration was used to show how tiny things are and how important it is for scientists to be able to study everything from small molecules up to planets and galaxies. Another famous illustration in science is that of a atom. An atom is the smallest particle of an element and it contains all the information about that element’s chemical properties. This illustration was used to show how atoms are related and how they can create new elements.
