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.

Physics
- April 24 – James Franck and Gustav Hertz's experiment on electron collisions showing internal quantum levels of atoms is presented to the Deutsche Physikalische Gesellschaft.

- Ernest Rutherford suggests that the positively charged atomic nucleus contains protons.
Technology
- February 3 – Willis Carrier patents an air conditioner in the United States.
- September 5 – British Royal Navy scout cruiser HMS Pathfinder (1904) is sunk by German submarine U-21 in the Firth of Forth (Scotland), the first ship ever to be sunk by a locomotive torpedo fired from a submarine.
- November 3 – Polly Jacob patents a backless bra in the United States.
- Kodak introduce the Autographic system.
Other events
- October 23 – Manifesto of the Ninety-Three proclaimed in Germany.
