“The best way to learn a topic is by teaching it. Similarly the best way to understand a new proof is by writing an expository article about it.”

“Mathematics my foot! Algorithms are mathematics too, and often more interesting and definitely more useful.”

“Let me also remind you that zero, like all of mathematics, is fictional and an idealization. It is impossible to reach absolute zero temperature or to get perfect vacuum. Luckily, mathematics is a fairyland where ideal and fictional objects are possible.”
