I loved Usenet. From comp.arch to rec.ski.nordic to rec.music.makers.piano and more I could find out things I wanted to know and people who were encouraging and kind. Yes there were trolls...oh yes very much and I did not feed them.

If you've ever used your body – arm span, foot, hand span – as a measuring device, you're partaking in a universal human practice that's verifiably thousands of years old.

Once upon a time I was practicing the theme from Moonlight Sonata in my car. Construction was going on and my sightline was a big pile of dirt. As I played two goundhogs emerged fro the dirt and started what I at the time viewed as affectionate and romantic nuzzling. Oh well. Maybe it was?

Every now and then an African American teacher will thank me for volunteering to do STEM+Art activities and call me "brother." I have to hold back tears in the moment. That someone could decide I am worthy of "brother" in the face of so much hate. Crying a bit now.

I read the article and her assertion - "mathematics is a language" makes good sense as part of a passion for helping people appreciate mathematics beyond their K-12 experience. Her perspective on what to do when functions can't be differentiated is interesting and provides some context.

A super faint edge-on disk galaxy, and somewhat of an enigma. How it formed like this and how its frontal morphology might appear are subject to speculation, but chances are if we saw it from a sufficiently inclined vantage point, it would be practically invisible beyond its nucleus, assuming what we see is spread out fairly evenly along the disk and not concentrated along some very skinny arms.

Anyway, I'm happy to simply enjoy yet another wonderful variation that nature has given us.

Mathematicians studied knots under "knot theory" for about a quarter of a millenium, but never analysed what kinds of knots humans have actually tied. In this paper we applied knot theory to study human-made knots spanning over ten millennia. Turns out some of our everyday knots are very old.
