Academic webpage of Dr. Eugene Kim https://kim3957.github.io/ Wed, 13 May 2026 08:02:51 +0000 A list of 50 brilliant minds who have significantly advanced our understanding of the world and contributed to making it a better place! Name Years Country Major Contributions Pythagoras 570-495 BC Greece Best known for the Pythagorean theorem, which relates the sides of a right triangle. His contributions also extend to musical theory and philosophical concepts of numbers and their relationships. Euclid circa 300 BC Greece Often referred to as the 'Father of Geometry,' Euclid's work 'Elements' is one of the most influential works in the history of mathematics, laying out the foundations of plane geometry. Nicolaus Copernicus 1473-1543 Poland...

So is equation \eqref{rotation}.
