Geoffrey Ernest Stedman (born 1 April 1943) is a New Zealand physicist, with research interests including the foundations of
relativity,
symmetry in quantum mechanics
Symmetries in quantum mechanics describe features of spacetime and particles which are unchanged under some transformation, in the context of quantum mechanics, relativistic quantum mechanics and quantum field theory, and with applications in the ...
, and
ring laser
Ring lasers are composed of two beams of light of the same polarization traveling in opposite directions ("counter-rotating") in a closed loop.
Ring lasers are used most frequently as gyroscopes (ring laser gyroscope) in moving vessels like cars ...

Education and career
Born in 1943, Stedman attended the
University of Canterbury
The University of Canterbury ( mi, Te Whare Wānanga o Waitaha; postnominal abbreviation ''Cantuar.'' or ''Cant.'' for ''Cantuariensis'', the Latin name for Canterbury) is a public research university based in Christchurch, New Zealand. It was ...
