Ronald Canti's ground-breaking stop-motion cinematic technique vividly illustrated the microscopic behaviour of normal and neoplastic cells; irradiation was shown to cause immobilisation and mitotic arrest in suspensions of cells.[8][9]

Georges Lemaître publishes in the Annales de la Société Scientifique de Bruxelles "Un Univers homogène de masse constante et de rayon croissant rendant compte de la vitesse radiale des nébuleuses extra-galactiques"[10] proposing the theory of the
expansion of the Universe, deriving what will become known as
Hubble's law, making the first estimation of what will become called the
Hubble constant,[11][12][13][14] and proposing what becomes known as the
Big Bang theory of the origin of the
Universe, which he calls his 'hypothesis of the
primeval atom'.[15][16]
