Mathematics

In analysis of the Riemann hypothesis
- G. H. Hardy shows there are infinitely many zeros on the critical line.^[6] 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;^[7] and R. J. Backlund introduces a better method of checking the zeros.

Pascoite is first described.^[9]

Physics

Technology
