  • Oh, what’s interesting about a nautical mile is that it wasn’t originally even based on a number of feet or meters or whatever. It represented one minute of latitude (60 minutes in a degree type of minutes). Since the earth is an oblate spheroid instead of a perfect sphere, that meant that traditional nautical miles varied based on your position until they were standardized it in 1929.

    I think it’s about 1.85 kilometers, but I wouldn’t have occasion to do the conversion because I’m a landlubber.


  • Walking. I take a long walk around the neighborhood and let my mind drift and eventually I find calm. I see some of the same people again and again and even though we’ve never spoken a word before, there’s a nod of recognition and I’m glad to see them. I get the impression they’re glad to see me too, which is a weird but fun kind of human relationship.


  • Yeah, absolutely, I’m not arguing in favor of making everyone do the memorization, I just think it’s interesting that it occurs after enough exposure.

    I’ve often thought that if we’d have evolved to have 6 digits instead of 5, we might have adopted a base 12 system and made fractional calculations a lot easier.

    Most people who deal in imperial units know off the top of their head that 1/3 of a mile is 1760 feet. They don’t have to calculate it. After a while you see that number come up often enough and it’s committed to memory.

    I’m not saying that metric isn’t better, it is, and I wish we would hurry up and switch to it. I’m just saying that the numbers involved aren’t a handicap once you have worked with the imperial system for a while. If you have a set of sockets that you work with every day, you know instantly that 3/8” is bigger than 19/64”. Hell, even 5/16” is bigger than 19/64”.

    And, you must admit, 333 meters is not one third of a kilometer. It is one third of 999 meters. The number 5280, for all its awkwardness, is beautiful in the sense that it is evenly divisible by 12, Meaning that it can be exactly divided into quarters, thirds, or halves without a fractional part.









  • Any of JS Bach’s works for organ. Toccata and Fugue in D minor is the most famous, but I mean the guy wrote like a million of them. Adagio and Fugue in C Major or Passacaglia and Fugue in C minor are a couple more examples that I find particularly nourishing. (I’ve never heard music described as nourishing before, but I like that. It’s a great way of putting it.)
