I have written about my name as a unique descriptor, and how to make one of yours.
But names are symbolic. What about using numbers to identify people? They would be easier to work with when using mathematics. An obvious candidate is birthdate.
I’m an old guy, from the middle of the last century, August 5th, 1949. But just to maintain my self-respect, let me just point out that it was in 1975, when I was just 26, that I first started to write about Social Technology, at 40 years before people started talking about “Social Apps”.
Anyway, that bit of egoism aside, that date is not a good enough descriptor. Lots of people were born on that day. Specifying birthplace in lat/long coords would help, but let’s just stick with times for now, as I used names on the previous page. I think all I need to do is add the birthdates of my parents: my mother, January 1st, 1920, and my father, June 6th, 192o. We have this little mnemonic for dates in our family: my mother was born on the first day of the first month, my father the 6th day of the 6th month, myself, the fifth day of the eighth month, my brother, the eighth day of the fifth month.
There will be people who are not sufficiently distinguished by just three birthdates. We have only one coincidence that I know of in my family, and only a partial one: both of my grandmothers were born on April 2nd — but on different years. Still, in this huge world of ours, there may be a case where three birthdates are not enough. If so, add the dates for grandparents. That is sure to be enough.
Using birthdates is perhaps the easiest unique descriptor to provide, but birthplaces are of some use too. More about that later.
