Physics simulations where a computer helps just try out different propeller designs to see how well it works has been helping introduce all kinds of super exotic designs in the last few years cause yeah as someone who did physics; "it's all just agreed upon expected outcome from trying it."

I'm a student pilot and most of my instructors (who are either retired airline pilots or are trying to build up flight hours to qualify for an airline job) don't understand the science behind it. To be fair, understanding the science doesn't really help you fly a plane... permalink fedilink source parent [–] NoMoreLurking@startrek.website 3 points 3 years ago (1 child) How do we not know how gravity works?? permalink fedilink source parent hideshow 1 child comment replies: [–] troglodytis@lemmy.world 3 points 3 years ago It's elusive, man.
