After 12/13/14, What Are the Next Fun Dates for Math Lovers?

After 12 13 14 What Are the Next Fun Dates for Math Lovers Science Smithsonian


For those of us in the United States, December 13 is auspicious because it will be the last sequential date of the 21st century: 12/13/14. The next such numerical alignment won't roll around for another 89 years. In Europe, this milestone has already passed, because folks there prefer to format dates starting with the day. For Europeans, 11 December 2013 (11/12/13) was the last sequential date of the century.

But numberphiles need not despair. Counting from one to 365 is just the simplest form of a mathematical tool called an integer sequence, says Neil J. A. Sloane, a visiting scientist at Rutgers University and founder of the Online Encyclopedia of Integer Sequences, or OEIS. "Our days are numbered," Sloane quips. So what other types of sequences can we look forward to celebrating this century?
