Lucky Fifteen


Today is Leslie and my fifteenth anniversary of marriage. Picked her up at the airport this afternoon and we went out for dinner at a trendy joint on the water, Island Prime.  View of the San Diego skyline was better than the food.  Food good but not foodie good. Highlights of the meal were a great multi dimensional lobster appetizer and a seagull that flew outside our window with a small halibut and had his dinner on the concrete patio next to us.  I am not going to go all Ruth Reichl on you and will spare you all the culinary details.

I am glad that my wife is home and hope that we are good for fifteen more years together (at least).  My life isn't quite right or complete without her.  I start moping and whistling that Police song - Bed's too big without you when she's gone.
Many of you were at the ranch for the wedding fifteen years ago. Time has flown but we've all remained friends.  Lost a couple we loved along the way.  I remember beautiful epiphyllum blooms all over the place, Silver Oak cabernet and a crabby Rabbi...  Thanks Shawn, for helping get the place together those many moons ago. I remember all of us holding hands in a circle out back. Joseph A. playing guitar.  No one's really changed all that much.
Take care, friends.

(fifteenth)

15 (fifteen) is the natural number following 14 and preceding 16. In English, it is the smallest natural number with seven letters in its spelled name.

In speech, the numbers 15 and 50 are often confused. When carefully enunciated, they differ in which syllable is stressed: 15 /fɪfˈtiːn/ vs 50 /ˈfɪfti/. However, in dates such as 1500 ("fifteen hundred") or when contrasting numbers in the teens, the stress generally shifts to the first syllable: 15 /ˈfɪftiːn/.

Fifteen is a triangular number and a hexagonal number, a pentatope number, and the 4th Bell number. Fifteen is the double factorial of 5. It is a composite number; its proper divisors being 1, 3 and 5. With only two exceptions, all prime quadruplets enclose a multiple of 15, with 15 itself being enclosed by the quadruplet (11, 13, 17, 19). 15 is also the number of supersingular primes.

15 is the 4th discrete biprime (3.5) and the first member of the (3.q) discrete biprime family. The number proceeding 15; 14 is itself a discrete biprime and this is the first such pair of discrete biprimes. The next example is the pair commencing 21.

The aliquot sum of 15 is 9, a square prime 15 has an aliquot sequence of 6 members (15,9,4,3,1,0). 15 is the fourth composite number in the 3-aliquot tree. The abundant 12 is also a member of this tree. Fifteen is the aliquot sum of the consecutive 4-power 16, and the discrete biprime 33.

15 and 16 form a Ruth-Aaron pair under the second definition in which repeated prime factors are counted as often as they occur.

Fifteen is the magic constant of the unique order-3 normal magic square:

15 is the smallest number that can be factorized using Shor's quantum algorithm.
