Hubble publishes the second part of his luminosity-function investigation, deriving statistical information from residuals in the observed velocity-magnitude relation of galaxies.
After discussions with Rudi Mandl, Einstein returned to the lensing calculation he had explored in 1912 and agreed to publish the optical effect of gravitational light bending.
With Philip Powers, independently demonstrates crystal diffraction of neutrons using magnesium oxide.
With Dana Mitchell, observes orientation-dependent Bragg reflection of neutrons from magnesium oxide.
With Eugene Wigner, formulates resonance theory for neutron-induced nuclear reactions.
With Gregory Breit, develops a resonance formula describing neutron capture by nuclei.
Cather published Not Under Forty, her collection of literary essays.
Yale University Press publishes Hubble's The Realm of the Nebulae, a systematic synthesis of his observational work on galaxies, distance scales, redshifts and the structure of the observable universe.

Einstein quantified the magnification produced by gravitational deflection in a simple stellar-lens geometry, linking image brightness to the angular alignment of source and lens.
Edwin Hubble and Glenn Moore publish observations of a supernova in the Virgo Cluster, adding a luminous stellar explosion in an external galaxy cluster to the developing record of supernovae.

Einstein's lensing note described how imperfect alignment can produce two apparent images of a background star because its light reaches the observer along different curved paths.
