encantado. igualmente.

February 1, 2010

So I started thinking about prime numbers, and why John Nash’s favorite prime would be 23. I think it’s because it’s the first prime number consisting of two consecutive primes: 2 and 3. I wonder if there’s a name for this kind of prime. The next one is 2,357, which shows you how common they are. Others include 3,137 (31 and 37), 5,711 (5, 7, and 11), 111,317 (11-13-17), 171,923 (17-19-23)… I found this site useful.

I found out the year of my birth, 1987, is a prime.

Then I started thinking about pi, how it goes on forever in a totally random, ever-changing sequence of digits. According to Cliff Pickover in Sex, Drugs, Einstein & Elves,

Recall that the digits of pi (in any base) not only go on forever but seem to behave statistically like a sequence of uniform random numbers. In short, if the digits of pi are normally distributed, somewhere inside pi’s string of digits is a very close representation for all of us. …We can even search for some of the first few consecutive runs using computer searches available on the Web. The string 123 is found at position 1924 counting from the first digit after the decimal point…1234 is found at position 13,807. 12345 is found at position 49,702, and so forth.

This means that you can eventually find your birthday in pi (Mine, 06111987, is found at position 148,775,398). Or your phone number, or your social security. Even a numerical representation of your DNA.

Sir or ma’am, you just got your mind blown.

(P.S. What’s the lowest number divisible by any number between 1 and 10? — 2,520)
