Definition: The word "Weierstrass" is a mathematical concept. It stands for William R. Weierstrass, an Austrian mathematician who developed several significant contributions to the theory of numbers. He introduced the concept of a sequence of numbers that converges or approaches a number as quickly and precisely as possible under certain conditions. This leads to new ways of approximating real numbers through the use of sequences. His work is deeply rooted in pure mathematics but has implications for many other areas like physics, computer science, and engineering.
