full_question: Processes named for this man can be constructed on an arbitrary symmetric inner product space with a countable basis using the Ito isometry. Weiner processes such as Brownian motion are examples of a broader class of processes named for this man. The pdf of this man's namesake distribution is a rescaling of e to the negative x minus mu squared over 2 times the variance. For 10 points, name this German mathematician whose namesake distribution is commonly called a bell curve.
