🧵 6/? Engineers love empirical laws. And, for the majority of engineering applications, they work extremely well. Take open channel flow, for example.

If you know how much water is going to flow, and you know the shape of your channel, and you can estimate "roughness," then, based on observations, you can apply the Manning's equation and (before climate change came and ruined the party) design drainage systems really well with a calculator. Gravity and friction are laws you can approximate.
