Chandrakant Raju (born 7 March 1954) is an Indian computer scientist, mathematician, educator, physicist and polymath. He received the Telesio Galilei Academy Award in 2010 for defining a product of Schwartz distributions, for proposing an interpretation of quantum mechanics, dubbed the structured-time interpretation, and a model of physical time evolution, and for proposing the use of functional differential equations in physics.
Early life and education
Raju was born on 7 March 1954 in Gwalior, Madhya Pradesh, India. He obtained a B.Sc. degree from the Institute of Science, Bombay (1973), an M.Sc. from the Department of Mathematics University of Mumbai, Bombay (1975), and a Ph.D. at the Indian Statistical Institute (1980).
Raju built on E.T. Whittaker's beliefs that Albert Einstein's theories of special and general relativity built on the earlier work of Henri Poincaré. Raju claims that they were "remarkably similar", and every aspect of special relativity was published by Poincaré in papers between 1898 and 1905. Raju goes further, saying that Einstein's failure to recognise the need for functional differential equations constitute a mistake that underlies subsequent relativistic physics. He proposes that relativistic physics must be reformulated using functional differential equations.  
Through his research, Raju has claimed that the Western philosophy of science, including its aspects that pertain to time  and the nature of mathematical proof are rooted in the theocratic needs of the Roman Catholic Church.
He has authored 12 books and dozens of articles, mainly on the subjects of physics, mathematics, and the history and philosophy of science.

The error is that the essential history-dependence of the relativistic many-body problem has been washed away by using a Taylor expansion in powers of the delay to convert a retarded functional differential equation into an ordinary differential equation.
