Abstract Wiener space

Abstract Wiener space is a mathematical way of thinking about how things can move in different directions at the same time. Imagine you have a room with no furniture in it. You can move around the room in any direction. That is like abstract Wiener space. Instead of thinking about things being stationary (not moving), we think about them being able to move in different directions at the same time. It helps us to better understand how things work in complicated ways.
