[edit] Biology
- January - Frederick Griffith reports the results of Griffith's experiment, indirectly proving the existence of DNA.[1][2]
- September 3 - Alexander Fleming, at St Mary's Hospital, London, accidentally rediscovers the antibiotic Penicillin, forgotten since Ernest Duchesne's original discovery in 1896.[3]
[edit] Computer science
- April - Leslie Comrie publishes an article "On the Construction of Tables by Interpolation", describing the use of punched card equipment for interpolating tables of data, and becomes the first to use such equipment for scientific calculations, using Fourier synthesis to compute the principal terms in the motion of the Moon for 1935–2000.
[edit] History of science
- Florian Cajori begins publication of A History of Mathematical Notations.
[edit] Mathematics
- David Hilbert and Wilhelm Ackermann publish Grundzüge der theoretischen Logik, a pioneering elementary text in first-order logic stating the Entscheidungsproblem.[4]
[edit] Medicine
- October 12 - An iron lung respirator is used for the first time, at the Children's Hospital, Boston.
[edit] Physics
- Paul Dirac proposes the Dirac equation as a relativistic equation of motion for the wavefunction of the electron,[5] leading him to predict the existence of the positron, the electron's antiparticle.[6]
[edit] Technology
- July 7 - The first machine-sliced and machine-wrapped loaf of bread is sold in Chillicothe, Missouri, using Otto Frederick Rohwedder's technology.
- September 3 - Philo Farnsworth demonstrates to the Press the world's first working all-electronic television system, employing electronic scanning in both the pickup and display devices.[7][8]

[edit] Births
- March 8 - Gerald Bull (died 1990), engineer.
- April 6 - James D. Watson, geneticist.
- April 20 - Charles David Keeling (died 2005), atmospheric chemistry, geochemistry, oceanography.
