A New Name; Real Numbers

January 19, 2012 – Comments (8)

Out with the BullnBear and in with the Aleph! I've changed my username to TMFAleph1. If anyone is interested, this is the significance of the new name:

German mathematician Georg Cantor came up with the concept as when he began ordering infinite sets -- yes, infinity comes in different sizes! Aleph-zero is the number of elements in the set of all integers, which is a countably infinite set (you can begin to count the integers even if you'll never get through them all.)

The set of real numbers (the "continuum"), on the other hand, is much larger – it's uncountably infinite and the number of elements it contains is 2 ^ aleph-zero (2 to the power of aleph-zero.)  According to the continuum hypothesis, aleph-one, which is the next largest size of infinity after aleph-zero, is equal to that number. You're probably wondering what any of this has to do with someone who writes about finance investing. Well, for one thing, those notions remind me of one of my favorite quotes in finance:

There is no hard line between arbitrage and speculation, it is a continuum.-- Stephen Ross, MIT

 Furthermore, aleph-one is tied to the real numbers and that's what I try to provide in my writing: The "real" numbers. Lastly, my writing and analysis should, at its best, present all of the characteristics under the meanings of 'real' that I have highlighted:

 re·al  adj  \ˈrē(-ə)l\

a : not artificial, fraudulent, or illusory : genuine <<em>real gold>; also : being precisely what the name implies real professional>

b (1) : occurring or existing in actuality real live celebrity> real life> (2) : of or relating to practical or everyday concerns or activities real world> (3) : existing as a physical entity and having properties that deviate from an ideal, law, or standard real gas> — compare ideal 3b

 c : having objective independent existence real>

 d : fundamental, essential

 e (1) : belonging to or having elements or components that belong to the set of real numbers real roots of an equation> real matrix> (2) : concerned with or containing real numbers <<em>real analysis> (3) : real-valued <<em>real variable>

 f : measured by purchasing power <<em>real income> <<em>real dollars

 That's the long and short of it (the long, really.) Fool on, as they say.

What's in the pipeline for when we get used to this one?

In the pipeline: Oodles of data. Historical data series of fundamental valuation indicators and asset returns, to be specific. I'll begin with the U.S., which has the highest quality and largest base of primary data, and I'll go on to look at other markets.

Haha, ok. You've always been one of my favorite writers. Might get hard to keep track of you if you keep changing your name a couple times a year.

Truth, ha, literally chuckled out loud.

Alex, I like.  You should know, and may already, there is already a nice finance/investing blog called alephblog.com, not sure if the reasoning was similar.  Guy's name who runs it is David Merkel, I follow him on Twitter.

I vote for long-term data.  I love this 220-year history of interest rates in the U.S.:

Thanks. It's with good reason that TMF discourages writers from changing usernames. I had to make a case for the change and I voluntarily pledged that the change is permanent -- TMFAleph1 is final.

Yes, I'm familiar with the Aleph blog; I'll be reaching out to David Merkel as a courtesy.
