Primes, Twin Primes, Triplets of Primes: How Many? (VIDEO!)

Euclid (ca. 300 BCE) proved that the list of primes (as single numbers) goes on forever. In this video we swiflty go over his proof, and then ask: What about twin primes (the pair 11-13, for example)? Does the list of those go on forever? What about triplets of primes (the tiple 3-5-7, for example)? Does that list go on forever?

    Written for educators - and their students too! - this website, slowly growing, takes all the content Tanton has developed in his books, videos, and workshops, and organizes it into short, self-contained, and complete, curriculum units proving that mathematics, at all points of the school curriculum, can be joyous, fresh, innovative, rich, deep-thinking, and devoid of any rote doing! Let's teach generations of students to be self-reliant thinkers, willing to flail and to use their common sense to "nut their way" through challenges, to assess and judge results, and to adjust actions to find success. (Great life skills!)
