I've been tracking personal coincidences, and they've been coming almost regularly, roughly twice a week.

Thinking about it mathematically, the totality of succinctly verbalizable ideas available is finite--just as an estimate I would say one million atomic ideas, and then if you allow modification by an adjective, then maybe a million million simple concepts in the idea space.

The actual number is probably much smaller, as the English language has less than one million words, and many of the word combinations are nonsense.

So say about one million simple concepts altogether.

And instead of working down from the high side, we can work up from the low side. Basic fluency in a language requires knowing about 2,000 words. Noun x modifier would then have roughly a quarter million different combinations--assuming one-fourth of the vocabulary was nouns, and another fourth was adjectives. Again, many of the combinations would be nonsense; almost unthinkable.

For a coincidence, the same somewhat obscure item has to appear twice within a reasonably short time.

I read a lot, and I have a lot going on around me, but not nearly enough to be expecting this sort of coincidence regularly.

I also don't recall noticing so many coincidences in years before 2020 or 2021, although in retrospect I do see a few oddities scattered across earlier decades.

Some of the coincidences that have come up recently are very striking, and a number of these are best attributed to God.
