...the source of all great mathematics is the special case, the concrete example. It is frequent in mathematics that every instance of a concept of seemingly generality is, in essence, the same as a small and concrete special case.
Paul HalmosRead
It is the duty of all teachers, and of teachers of mathematics in particular, to expose their students to problems much more than to facts.
Interpretation
Teachers should focus on presenting students with problems to solve rather than just facts to memorize.
In this quote, Paul Halmos emphasizes the importance of engaging students with challenging problems in mathematics rather than solely delivering factual knowledge. This approach encourages critical thinking and deeper understanding, fostering a learning environment where students learn to apply concepts and develop problem-solving skills, which are vital for their growth and success in the subject and beyond.
In practice
In a seminar on innovative teaching methods, I would use this quote to explain the importance of problem-based learning.
...the source of all great mathematics is the special case, the concrete example. It is frequent in mathematics that every instance of a concept of seemingly generality is, in essence, the same as a small and concrete special case.
[Mathematics] is security. Certainty. Truth. Beauty. Insight. Structure. Architecture. I see mathematics, the part of human knowledge that I call mathematics, as one thing - one great, glorious thing. Whether it is differential topology, or functional analysis, or homological algebra, it is all one thing. ... They are intimately interconnected, they are all facets of the same thing. That interconnection, that architecture, is secure truth and is beauty. That's what mathematics is to me.
Economists have put themselves in a position where what they are doing is supposed to be impossible to understand for outsiders, so they don't even talk - sometimes not even with their girlfriend or boyfriend or friends - about what they are doing.
It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration.
Results show that just one year of chess tuition will improve a student's learning abilities, concentration, application, sense of logic, self-discipline, respect, behavior and the ability to take responsibility for his/her own actions.
The academic bias against subjectivity not only forces our students to write poorly ("It is believed...," instead of, "I believe..."), it deforms their thinking about themselves and their world. In a single stroke, we delude our students into believing that bad prose turns opinions into facts and we alienate them from their own inner lives.
The age of the pulp magazine was the last in which youngsters, to get their primitive material, were forced to be literate.
My brother and I were both good at science, and we were both good at English literature. Either one of us could have gone either way.
