Scottish Cafe Teaching mathematicians Banach and Uram
Celebrities-famous Polish mathematicians Banach and Ulam
Banach and Ulam, famous Polish mathematicians, are the main members of a certain mathematical school. They love coffee shops, for hours at a time, and even the mathematical concepts of Banach space and Banach algebra taste like coffee. They scribbled on their desks with pencil filled with sophisticated mathematical formulas. The owner of the cafe saw it and felt sorry for his table, but he did not want to offend the guests. Therefore, the boss prepared a book in advance and placed it on the coffee table together with the coffee when the mathematicians came. This is the world-famous Scottish Manual that has been handed down to this day. From 1935 to 1941, the manual recorded 193 mathematical problems, most of which remain unsolved. The history of mathematics calls it "Scottish cafe teaching." Later, Ulam went to the United States and became an important diamond in atomic bomb research. In his later years, he was nostalgic for his Scottish cafe days.
