This reading we derive from Georg Cantor, the German mathematician who explored the cardinality of infinite sets. He found that though the natural numbers – 1, 2, 3 and so on – were infinite, still there were fewer of them than there were “real” numbers like root 2, pi, and 0.239567990052… Indeed, not only were there two different levels of infinity, but it seemed likely that there were an infinite number of different infinities (and maybe one extra, to describe the number of infinities there were?)

“It has seemed to me for many years indispensable to fix the transfinite powers or cardinal numbers by some symbol, and after much wavering to and fro I have called upon the first letter of the Hebrew alphabet, aleph. The usual alphabets seem to me too much used to be fitted for this purpose; on the other hand, I didn’t want to invent a new sign.”
A pragmatic account, utterly without reference to a two-thousand-year-old tradition of using the aleph to signify God. Nothing is ever a coincidence. The genealogies say his grandparents were Sephardic Jews, and if they weren’t kabbalists I will eat my hat.
