  • 4 of these things actually happened this year, in New England too (where Randall at least used to live).

    We had perfect clear skies for the eclipse in Maine, then a couple months later had visible Aurora on a clear night as well. All while the cicadas were around, though they weren’t very loud in my area.

    Not all on one day, but pretty lucky in a year. My 6 year old’s expectations for celestial events are set pretty high now though.

    Yeah I’m mostly just shitting on it for fun too. But the pistons don’t work very long without steel rings, wrist pins and big end bolts.

    The problem is we have to bring copper, brass and other fancy metals in them though, because the all spin on oil cushion bearings. Unless we’re talking Babbitt bushings from the early 1900s.

    Most cars are still steel. Source I work on cars in New England. So much rust, even on the ones with aluminum bodies, at least wherever it can touch a dissimilar metal and becomes a battery.

    And crucially the important parts that keep it from exploding (cylinder liners) and save you in a crash (crumple and bumper cores) are almost all steel. Because it deforms better with simpler engineering.

    See also iron brakes in most cars hardened steel bearings everywhere.



  • Yeah I’m a pretty strong swimmer, grew up with a pool and set a record in freestyle at a high school pool when I was in 8th grade. I also grew up with twin cousin swim team guys to chase around the pool and play tag/dunk/wedgie/pants generally torture each other.

    I’m also 6’3 and fairly strong, but waterpolo players are nuts. It’s a lot like lacrosse, where there are tons of dirty tricks that can be hidden from refs and really hurt. I played both sports a few times with seasoned players, never again. Especially lacrosse my elbows still hurt thinking about it 20 years ago.
