...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.
No one should be held back from realising their potential by fears that they will not be able to afford to go to university or that they will graduate with unmanageable levels of debt.
Schools shouldn't have to choose between serving a student with special needs or cutting an art class, laying off teachers or using outdated textbooks. But these are the positions that far too many schools have been placed in, and only a meaningful acknowledgment of the problem can begin the process of getting them out.
I feel it is now my duty to speak to young women, to encourage them to have careers and, particularly, careers in science.
The more important argument against grade curves is that they create an atmosphere that's toxic by pitting students against one another. At best, it creates a hypercompetitive culture, and at worst, it sends students the message that the world is a zero-sum game: Your success means my failure.
I don't want to write for adults. I want to write for readers who can perform miracles. Only children perform miracles when they read.
Every society needs educated people, but the primary responsibility of educated people is to bring wisdom back into the community and make it available to others so that the lives they are leading make sense.
