When is 111…111 prime?
July 1, 2011
When you’re on facebook, you’ll see a lot of people posting a lot of silly things. It would be interesting to see what kinds of things are posted when, but this is a subject for some kind of cybersociologists. Nonetheless, if you are awake at around 11pm and on facebook (and, I’ll admit it, I’m one of these people), you might see a string of comments that essentially say: "omg, it’s 11:11, make a wish."
If you’re superstitious or obsessive compulsive, this might be a lucky reminder to make a wish at this time, but besides its symmetry and visually appealing form, what’s so special about 1111?
