New round of #introductions for all the new people joining the Fediverse!

Hi, I’m Kelson (he/him), a computer programmer in the Los Angeles area. I talk about all kinds of things here: #scifi/#fantasy, #books, actual #science, #tech, #history, #linguistics, random day-to-day stuff, etc.

I also post photos – mostly cityscapes/landscapes, nature, random interesting stuff I’ve spotted IRL – on Pixelfed (@KelsonV) and more “serious” photos on photog.social (@kelsonv)

Florida’s Cannonball-Eating Spanish Fort

“The Mystery of Florida’s Cannonball-Eating Spanish Fort”

The rock it’s made from, coquina, is a sedimentary rock made up of compressed seashells. It turns out that under impact, the component shell fragments can shift, absorbing the impact. This explains why cannonballs simply sank into the walls like pressing into foam instead of shattering them.

Fascinating: At the Guédelon medieval construction site in central France, builders are reconstructing a 13th century castle using only the technologies and materials that were available at the time. Hand-quarried stone cut with hand-forged tools, treadwheel cranes, etc.

A medieval castle in France could be Notre Dame’s salvation
