In this talk, he first outlines how all the world’s data can be stored on a speck of dust. He then makes

He then, with characteristic certainty, makes this statement –– “ It would be very easy to make an analysis of any complicated chemical substance; all one would have to do would be to look at it and see where the atoms are”. Now, examine the case of high-Tcoxide superconductors [The Nobel Prize in Physics 1987: J. Georg Bednorz, K. Alex Müller], for which its discoverers, J.G. Bednorz and K.A. Müller, received the Nobel Prize in 1987, and address the following questions: (i)Is the structure, including the position of atoms in the perovskite unit cell, for these high-TcYBa2Cu3O7oxides well-known ? (ii)Has this led to an understanding of why these materials are superconducting ? (iii)Does this prove or refute the arguments of Prof. Feynman ? Please explain.
