Quasars, extremely distant and luminous sources of strong radio waves and other forms of energy, are discovered.
American geophysicists Richard Doell, Allan Cox and Brent Dalrymple chart the irregular schedule of the Earth’s polarity changes based on extensive studies of the magnetic properties of rocks from different periods of time.
Karl Strnat discovers the first generation of rare-earth permanent magnets.
The electroweak theory is developed to unify quantum electrodynamics with the theory of weak interactions (also known as weak nuclear force).
The first superconducting magnetic energy storage (SMES) system, designed to store energy in the magnetic field created by the flow of direct current in a coil of cryogenically cooled superconducting material, is proposed in France, though it is deemed too expensive to build.
Apollo spacecraft survey the magnetic field of the Earth's moon.
Americans Karl Strnat and Alden Ray develop the second generation of rare-earth magnets.
Greek physicist John Iliopoulos presents, for the first time in a single report, the view of physics now called the Standard Model, a theory which describes the strong, weak and electromagnetic fundamental forces as well as the fundamental particles that make up all matter.
The magnetic satellite known as Magsat is launched as a joint venture of NASA and the U.S. Geological Survey to undertake the first precision mapping of the near-Earth magnetic fields.
