Examples of floating point problems

Link. “Several people mentioned issues with sending floats in JSON, whether either they were trying to send a large integer (like a pointer address) in JSON and it got corrupted, or sending smaller floating point values back and forth repeatedly and the value slowly diverging over time.”

Ok,that’s real bad.

Modeling the size of the observable universe – a 2022 take.

Link. Emphasis on OBSERVABLE. It’s likely the universe is far larger than what we can observe. I particularly liked that stars, in an odd way, are sparser than galaxies… ” If the Milky Way were a grapefruit in Seattle, WA, then Andromeda — the Local Group’s largest galaxy located 2.5 million kilometers away — would be a grapefruit in the same room, only about 10 feet … away” Recommend that vertical log map.
