They weren't brothers and none of them were called Walker, but when Scott 'Walker' utters that first word, 'loneliness', you know something big is coming your way and it may not be good news.
Scott was a reclusive, often troubled guy whose solo work, especially in later years, was very left field and avant-garde. If you are feeling brave, check it out.
Brownian dynamics have become ubiquitous in the mathematical modelling of noisy real-world systems. Typically, one considers the interplay between the governing forces of the system and the random fluctuations that occur due to noise. This culminates in the mathematical framework of stochastic differential equations (SDEs), which have found applications in finance, biology, and far beyond.

Abstract
Ken Brown reviews the history of the question in the title, and describes some recent progress towards answering it, including the identification of a "minimal criminal". The new material is joint work with Jason Bell (Waterloo) and Toby Stafford (Manchester).
