Worm moon

春分 starts today, and 啓蟄 is over yesterday. I just learn on Grammar Girl podcast that today's full moon is called worm moon. As 啓蟄 means the time of year when worms start their activities after winter, it is referring to same aspect of nature.

Using the clock face to know if a number is divisible by four

It's relatively easy to reckon whether a number is divisible by four if it's less than 50.
It becomes difficult when it's greater than 50, though you can use a trick of subtracting 50 from the number and see if the difference is divisible by four or not; if it is the original number is not a multiple of four.
The easier way I found is to use the clock face. Using the hour mark for numbers, those divisible by four are located at 12, 4, and 8 o'clock. If you are familiar with the clock face you instantly know 16 or 20 is a multiple of four since it positions at one of those hour marks.
Next. There's a connection between hourly marks, 12 hours around the clock and minute marks, 60 minutes around the clock. Notice the 15 minute mark, 30-minute mark, and so on coincide with 15-hour mark, 30-hour mark respectively. This fact and the fact that those divisible by four are located at particular positions on the clock face help you figure out if a number is a multiple of four.
Take, for example, number 92. Since the 90‑hour mark is at 6 o'clock position, 92 is located at 8 o'clock position, so it's easy to see it's divisible by four.

Legible vs. Readable

I found a good example:

MNEMONIC vs. Mnemonic or mnemonic

Ever since I started working, I always had a sense that working in company setting is not for me.
I also felt Japanese is not my kind of language, too much to do with graphical aspect of the language at the expense of phonetic elements. But then I was not proficient in any other language other than Japanese. Has it changed now that I got proficiency in English at some level, and I can prose what I have in my mind in English fairly quickly as I'm doing right now?
Being able to write proficiently in one language still is different from using the language for thinking. You must be able to read what you've written, make correction to it, develop from there to the next iteration. In that view, I don't think I can read what I write effective enough to take advantage of it.
But as I was doing this experiment on Firefox and then on Chrome, copying by hand reading on Firefox and writing on Chrome, I incorporated several changes, and that's easy to do for me. Maybe this way I can develop what I have in my mind to take shape progressively.
