“If you are ever forced to take a chemistry class, you will probably see, at the front of the classroom, a large chart divided into squares, with different numbers and letters in each of them. This chart is called the table of the elements, and scientists like to say that it contains all the substances that make up our world. Like everyone else, scientists are wrong from time to time, and it is easy to see that they are wrong about the table of the elements. Because although this table contains a great many elements, from the element oxygen, which is found in the air, to the element aluminum, which is found in cans of soda, the table of the elements does not contain one of the most powerful elements that make up our world, and that is the element of surprise”
