A great mathematician passed away on May 20th, Walter Rudin. I've come to know his name well from his famous text on mathematical analysis, Principles of Mathematical Analysis, affectionately called Baby Rudin. A tiny hard blue cover encases this thin book that encompassed my life all of last year. His dense writing had no fluff, deep analysis with little explanation and little to no hand-holding. Very elegant math.
