Turning a Nail Polish Disaster Into a Teachable Math Moment

theodp writes: In The Spiral of Splatter, SAS's Rick Wicklin writes that his daughter's nail polish spill may have created quite a mess, but at least it presented a teachable math moment: "'Daddy, help! Help me! Come quick!' I heard my daughter's screams from the upstairs bathroom and bounded up the stairs two at a time. Was she hurt? Bleeding? Was the toilet overflowing? When I arrived in the doorway, she pointed at the wall and at the floor. The wall was splattered with black nail polish. On the floor laid a broken bottle in an expanding pool of black ooze. 'It slipped,' she sobbed. As a parent, I know that there are times when I should not raise my voice. I knew intellectually that this was one of those times. But staring at that wall, seeing what I was seeing, I could not prevent myself from yelling. 'Oh my goodness!' I exclaimed. 'Is that a logarithmic spiral?'" So, got any memorable teachable math moments you've experienced either as a kid or adult? Yes, Cheerios Math counts!

      Fine, I have a better citation than the AC.

      A prime number (or prime integer, often simply called a "prime" for short) is a positive integer p>1 that has no positive integer divisors other than 1 and p itself. (More concisely, a prime number p is a positive integer having exactly one positive divisor other than 1.) For example, the only divisors of 13 are 1 and 13, making 13 a prime number, while the number 24 has divisors 1, 2, 3, 4, 6, 8, 12, and 24 (corresponding to the factorization 24=2^33), making 24 not a prime number. Positive integers other than 1 which are not prime are called composite numbers.

      Prime numbers are therefore numbers that cannot be factored or, more precisely, are numbers n whose divisors are trivial and given by exactly 1 and n.

      While the term "prime number" commonly refers to prime positive integers, other types of primes are also defined, such as the Gaussian primes.

      The number 1 is a special case which is considered neither prime nor composite (Wells 1986, p. 31). Although the number 1 used to be considered a prime (Goldbach 1742; Lehmer 1909, 1914; Hardy and Wright 1979, p. 11; Gardner 1984, pp. 86-87; Sloane and Plouffe 1995, p. 33; Hardy 1999, p. 46), it requires special treatment in so many definitions and applications involving primes greater than or equal to 2 that it is usually placed into a class of its own. A good reason not to call 1 a prime number is that if 1 were prime, then the statement of the fundamental theorem of arithmetic would have to be modified since "in exactly one way" would be false because any n=n1. In other words, unique factorization into a product of primes would fail if the primes included 1. A slightly less illuminating but mathematically correct reason is noted by Tietze (1965, p. 2), who states "Why is the number 1 made an exception? This is a problem that schoolboys often argue about, but since it is a question of definition, it is not arguable." As more simply noted by Derbyshire (2004, p. 33), "2 pays its way [as a prime] on balance; 1 doesn't."

      With 1 excluded, the smallest prime is therefore 2. However, since 2 is the only even prime (which, ironically, in some sense makes it the "oddest" prime), it is also somewhat special, and the set of all primes excluding 2 is therefore called the "odd primes." Note also that while 2 is considered a prime today, at one time it was not (Tietze 1965, p. 18; Tropfke 1921, p. 96).
