Newtonian mechanics is the mathematical limit of quantum mechanics for ħ -&gt; 0. It is still taught to every physics major. It is still useful. We use it to calculate whether a bridge will collapse, to simulate car crashes, to simulate water flow, and I believe even NASA uses it to calculate rocket trajectories. The heliocentric model on the other hand is just wrong.<p>It is important to make this distinction if you want to accurately understand scientific revolutions. It is not accurate to think that quantum mechanics was just this new thing that replaced Newtonian mechanics. One has to keep the precise correspondence between Newtonian and quantum mechanics in mind. This isn&#x27;t just a narrative that scientists use to feel good about Newton.<p>This brings into question whether revolution is a good word for this phenomenon.
