Last week, I introduced Emmy Noether, an extraordinary figure in the fields of mathematics and physics. To understand Noether ...

How Emmy Noether's theorem uses the Lagrangian to provide a formula for calculating the quantity of symmetries in a system—like the orbit of planets.

I just read a very insightful NY Times article entitled The Wrong Way to Teach Math by Andrew Hacker, a Professor Emeritus at Queens College in NY. Hacker teaches political science and mathematics and ...

IN your issue of January 29, Mr. Heaviside put forward a demonstration of Lagrange's equations of motion which appears invalid. As neither his interpretation of Newton nor his argument based thereon ...
