In this web content, Isaac Asimov receives a letter from a reader who is majoring in English Literature but feels the need to teach Asimov about science. Asimov reflects on his previous statement that we finally understand the basic rules of the Universe and acknowledges that people in every century have thought the same thing and been proven wrong. He argues that “right” and “wrong” are not absolute concepts, but rather fuzzy ones. Asimov uses the example of the belief in a flat Earth and explains the gradual transition to the understanding of a spherical Earth. He concludes by stating that even the notion of the Earth being a sphere is not completely accurate, as it is actually oblate spheroidal in shape.
