December 18 – Epimetheus, another of the moons of Saturn, is discovered, but mistaken for Janus which shares its orbit and they are not distinguished until 1978.
The first live specimen of a mountain pygmy possum (Burramys parvus), Australia's only truly hibernating marsupial, previously known only from the fossil record, is discovered.[3]
September 1 – While waiting at a bus stop Ralph H. Baer, an inventor with Sanders Associates in the United States, writes a four-page document that lays out the basic principles for creating a video game to be played on a television: the beginning of a multibillion-dollar industry.
Euler's sum of powers conjecture is disproven by L. J. Lander and T. R. Parkin when, through a direct computer search on a CDC 6600, they have found the counterexample 275 + 845 + 1105 + 1335 = 1445. Their paper[8] announcing the result is one of the shortest published scientific articles ever published.
