Math concepts introduced by physicists and made rigorous later

The prime example is Newton's Calculus. The notions of limit, convergent series, derivative and integral were made rigorous (to our modern standard) only in 19th century. In Newton's time, even the ...

Math concepts introduced by physicists and made rigorous later

Ok, at least as a place-holder: Much of Euler's work. :) George Green's 1828 idea now called "Green's function". The "Sturm-Liouville equation" thing, c. 1830, was very good, but ...

Math concepts introduced by physicists and made rigorous later

Leibniz applied his infinitesimal calculus to solve numerous problems that today would be considered elementary physics. Several such applications are analyzed by McDonough in his book Jeffrey K. ...

Math concepts introduced by physicists and made rigorous later

Wavelets were first studied by physicists in the 1970s. Their study by mathematicians took off in the 1980s. Some work decades earlier by Haar, a mathematician, can be viewed as belonging to the study ...

How did Schrödinger do quantum mechanics with wave functions?

I don't think Heisenberg and Schrödinger calculated probabilities at the beginning, as the role of probabilities in quantum mechanics was not known then. Schrödinger initially interpreted the squared ...
