Physics
- William Henry Bragg and William Lawrence Bragg work out the Bragg condition for strong X-ray reflection.
- Niels Bohr presents his quantum model of the atom.
- Robert Millikan measures the fundamental unit of electric charge.
- Georges Sagnac demonstrates the Sagnac effect, showing that light propagates at a speed independent of the speed of its source.
- Johannes Stark demonstrates that strong electric fields will split the Balmer spectral line series of hydrogen.

Famous quotes containing the word physics:
“The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.”
—Erich Fromm (1900–1980)
“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
—Alfred Döblin (1878–1957)
“But this invites the occult mind,
Cancels our physics with a sneer,
And spatters all we knew of denouement
Across the expedient and wicked stones.”
—Karl Shapiro (b. 1913)
