The year 1916 involved a number of significant events in science and technology, some of which are listed below.

Astronomy

• Barnard's Star is discovered by Edward Emerson Barnard.
• Harlow Shapley finds that the spectrum of S Sagittae and other Cepheid variables varies with brightness, recording it as spectral type F0 leading to maximum, F4 at maximum, and G3 just before minimum brightness.

Chemistry

• Gilbert N. Lewis and Irving Langmuir formulate an electron shell model of chemical bonding.
• Sydney Chapman and David Enskog systematically develop a kinetic theory of gases.
• Jan Czochralski invents a method for growing single crystals of metals.

Mathematics

• Ludwig Bieberbach presents the Bieberbach conjecture.
• Wacław Sierpiński gives the first example of an absolutely normal number and describes the Sierpinski carpet.

Medicine

• January 1 – The British Royal Army Medical Corps carries out the first successful blood transfusion using blood that had been stored and cooled.
• October 16 – Margaret Sanger opens a family planning and birth control clinic in Brownsville, Brooklyn, the first of its kind in the United States. Nine days later, she is arrested for breaking a New York state law prohibiting distribution of contraceptives. This same year, she publishes What Every Girl Should Know, providing information about such topics as menstruation and sexuality in adolescents.
• Georges Guillain, Jean Alexandre Barré and André Strohl diagnose two soldiers with Guillain-Barré syndrome of the peripheral nervous system and describe the key diagnostic abnormality of increased spinal fluid protein production, but normal cell count.
• Eugen Bleuler publishes his Lehrbuch der Psychiatrie, including a definition of complexes arising from diffuse brain damage, known as "Bleuler's psycho syndrome".

Physics

• Albert Einstein publishes "Die Grundlage der allgemeinen Relativitätstheorie" on general relativity in Annalen der Physik 49 and shows that the field equations of general relativity admit wavelike solutions.
• Karl Schwarzschild solves the Einstein vacuum field equations for uncharged spherically-symmetric non-rotating systems.

Psychology

• Lewis M. Terman of Stanford University develops the first of the Stanford–Binet Intelligence Scales for intelligence testing.

Technology

• April 18 – Capt. Peter Nissen completes the prototype Nissen hut.
• September 11 – The almost-completed Quebec Bridge collapses for the second time.

Events

• Chemist Chika Kuroda becomes the first woman in Japan to receive a Bachelor of Science degree.
