Oxymorphone, a powerful narcotic analgesic closely related to morphine, is first developed in Germany.[6]
Chemistry
T. W. Richards finds variations between the atomic weight of lead from different mineral sources, attributable to variations in isotopic composition due to different radioactive origins.[7][8]
G. H. Hardy shows there are infinitely many zeros on the critical line.[9]Harald Bohr and Edmund Landau show that for any positive ε, all but an infinitely small proportion of zeros lie within a distance ε of the critical line;[10] and R. J. Backlund introduces a better method of checking the zeros.
