Edward William "Ted" Bastin (8 January 1926 – 15 October 2011) was a physicist and mathematician who held doctorate degrees in mathematics from Queen Mary College, London University and physics from King's College, Cambridge, to which he won an Isaac Newton studentship. For a time, he was Visiting Fellow at Stanford University, California and a Research Fellow, King's College, Cambridge, England.

Bastin’s research specialties included the foundations of physics, especially the discrete and finite aspects of quantum mechanics and relativity. He believed that a view of physical space in which space is defined not as a continuum but as a finite set of points was capable of resolving the clash between the continuum aspect of the classic theory of relativity and the discrete aspect of quantum physics. He was strongly influenced by Eddington's view that the various dimensionless and cosmological constants such as the fine structure constant had a unique status or significance as constraints upon the possible values of the natural atomic and cosmological constants of which they are ratios, and hence on all possible measurements. Along with Frederick Parker-Rhodes, Clive W. Kilmister and John Amson, Ted Bastin is noted for the discovery of, and research on applications of, the so-called combinatorial hierarchy which defines this view of space. While at the Cambridge Language Research Unit (founded by Margaret Masterman) he and Parker-Rhodes used Maurice Wilkes' EDSAC to compute the combinatorial hierarchy. However, the theory gave rise to no testable predictions and was generally regarded as too speculative.
He was on firmer ground in his objection to the (then generally accepted) Copenhagen interpretation of quantum theory, and also to other conceptual difficulties, such as the nature and role of observation and measurement, which he regarded as contributing to logical muddle arising from confusing ontological and epistemological aspects of the theory. His assessment of the philosophical difficulties and obscurities in quantum theory that had to be overcome before any change in the basic structure could take place was penetrating; it was only his attempt to overcome the formal difficulties that failed.
