M.Polanyi and T.Kuhn were both famous for successfully changing from scientists to philosophers, guiding the philosophy of science to a social-history field.They had similar backgrounds which made them fall into the same academic field.Lots of scholars have taken Kunh's works as the reprints of Polanyi's.However when Kuhn gained tremendous prestige and showed no explicit attitudes towards Polanyi's works, he got into a dispute with Polanyi over their priority in the philosophy of science and technology.
