Writing about all these fields would go beyond our domain of expertise and would rely on too many examples. Therefore, for the remainder of the paper, we will use the field of quantum chemistry as an example, but the reader can have in mind, that very similar arguments could be made for any of the other theoretical/computational fields mentioned above, as they are all connected to the developments in fundamental, physical theory in the first half of the twentieth century and the dramatic hardware and algorithm developments in its second half.
