R Sacks Z’L spoke movingly about his teacher R Nachum Rabinowitz, who in turn had a semicha from Ner Isroel and PhD in statistics. (aside: R Rabinowitz writings on use of probabilities are breath-taking).
R Sacks is a universalist, most reminding of R Shimshon Hirsh. He is able to put Torah learning in terms that can be understood – and valued – by nations of the world, and explain to Jews how Torah relates to modern life and modern philosophies, something that this Coffee Room often concerns about.
