Would a knowledgeable person be able to explain the following to a rookie: if the quantum physics equation describe a reality (or "phenomenons") which cannot be comprehended in the non-quantic reality (ie. classical physics), how can there be common patterns in both realities where equations from one realm would somehow still match patterns in the other realm ? |

Some problems need all que quirks of quantum mechanics, but other can be simplified and you get a simplified equation.
For example the electrons moving inside a very pure and very cold conductor are weird but if you have a normal conductor at room temperature, you can use the usual equation V=I*R to calculate the current. The simplified equation V=I*R is not 100% exact, probably only 99.99999999999% so everyone use it.
The same equation can be used to calculate flux of water inside tubes, when the speed of the water is low. You must replace the voltage V with the pressure P, and other similar replacements. When the speed is high, you get more complicated equations, but in some cases the simplified equation is good enough.
The idea is that in some conditions, both system can be approximated with a simplified equation, in spite under the hood they are very different.
