“একজন বিখ্যাত মানুষ দিয়ে কি হয়?, কিছুই হয় না ।কিন্তু একশটা খাঁটি মানুষ দিয়ে একটা দেশ পাল্টে দেয়া যায় ।তাই চেষ্টা করতে হয় খাঁটি মানুষ হওয়ার।”
― Muhammed Zafar Iqbal, দুষ্টু ছেলের দল

“In fact, most of these comrades who I gauged to be more brilliant than I have gone on to become distinguished mathematicians. Still, from the perspective of thirty or thirty-five years, I can state that their imprint upon the mathematics of our time has not been very profound. They've all done things, often beautiful things, in a context that was already set out before them, which they had no inclination to disturb. Without being aware of it, they've remained prisoners of those invisible and despotic circles which delimit the universe of a certain milieu in a given era. To have broken these bounds they would have had to rediscover in themselves that capability which was their birthright, as it was mine: the capacity to be alone.”
― Alexander Grothendieck

“Don't let self-imposed, unnecessary restrictions limit your thinking. Whenever you encounter a problem, it is worth spending a minute (or more) asking the question: 'Am I imposing rules that I don't need to? Can I change or bend the rules to my advantage?”
― Paul Zeitz, The Art and Craft of Problem Solving

“People don't do mathematics because it's useful. They do it because it's interesting.”
― Paul Lockhart, Measurement
