    1. If the bridge stays up, it was a good approximation. If it falls, it was a ‘statistical anomaly’

    2. Im mechanical engineering student, we sometimes take the g=10 if there are too many calculations in rest of the problem

      Rounding gravity is how you end up with a bridge that is technically safe but feels like a trampoline.

    4. I am studying mechanical engineering. I know 35 digits of pi, but when your diameter is only correct on 2 digits, it doesnt make a better calculation if you take more digits.
      When I calculate in my brain to check whether the solution could be correct, I also use pi=3 and g=10, because it is easier to calculate and I do only want to get near my calculator solution.

      It’s close enough, and if something is sturdy enough to not collapse with a gravity of 10m/s², it’ll probably be fine with the real value

    6. Idk about you guys but I’m fine with a civil engineer overestimating gravity. A bridge built for 1.02 G will hold up just fine in 1 G.

      Wrong unit though. That’s a problem

    7. Accuracy depends on the application. If you’re trying to setup your equipment yo detect gravitational waves, it’s not good enough but if you’re laying concrete to repair the sidewalk then its fine

      This pissed me off so much last semester because my physics professor never told us she was grading our calculations with a key where everything was calculated with b=10m/s^2 and it took HALF THE SEMESTER to figure out why my grades were so bad. All in the name of “simplifying the calculations” which is total bs

      Is the joke in the fact that he’s 12 years old and has to use a font half the size of the screen, as well? Like in Farside’s “school for the mechanically declined”? 🤣
