The year 1964 in science and technology involved some significant events, listed below.

Astronomy and space exploration

  ESRO
  (European Space Research Organization) is established (under an agreement of June 14, 1962).

  and even some games consoles.
• PL/I (Programming Language I), a block-structured computer language, is created by George Radin, while at IBM.
