What is a Random Walk?

The video explores the concept of random walks, their mathematical foundation, and applications in various fields such as Google's search algorithm, finance, and biology. It explains the basic random walk on integers, extends the concept to higher dimensions, and introduces biased random walks. The video also discusses the recurrence and transience of random walks, their relation to Markov chains, and various applications including the stock market and Gambler's Ruin. Viewer feedback and a PBS survey are also mentioned.
