ODTÜ'de uzun yıllardır görülen en sert polis müdahelelerinden biri devam ediyor. Yüzlerce sıra arkadaşımız saatlerdir geri adım atmadan yoğun biber gazı ve plastik mermi saldırısına direniyor.

This Grothendieck quote is the best-kept secret about mathematics:
Always start with your naive intuition, even if it’s plainly dumb, and then refine it by asking a barrage of “stupid” questions. Waiting in silence until you “get it right” will only lead to paralysis.
@fermatslibrary Another example of this phenomenon: For any real numbers x and y in [-1,1], there exists a natural number n such that x<cos(n)<y, in other words, A={cos(n) | n is a natural number} is dense in [-1,1]. A has cardinality aleph zero and [-1,1] has cardinality 2^(aleph zero).
@miniapeur Consider f(x)=x where x∈ℤ, f is continuous but it cannot be drawn without lifting your hand. I guess calculus student is correct only when the domain is an interval.
