Repost on the Winter Solstice — Shortest Day & Longest Shadows, or No

Solstice was yesterday but I like this post,

Like most mariners, back in the day, I leaned celestial navigation by rote, When you’re down in the weeds doing triple interpolation it’s difficult to see the connection from that to an LOP.’

But this, while not really useful does ground things to some degree.

“Should a man start from the Tropic of Cancer at the winter solstice and walk 18 miles per day northward for six months, his shadow would remain nearly the same each day at noon.”
