Governing laws of quantum mechanics

[revo74]

Laymen here.

I have been told that the motion of particles at the quantum level are random. If this is not true please elaborate.

Whether this is the case or whether there is a pattern waiting to be discovered, isn't it true that the world at the quantum level is still governed by mathematically precise laws as it is at the level of general relativity?

I have been told that the motion of particles at the quantum level are random. If this is not true please elaborate.

At least the appearance of most microscopic events look random to us, and the standard textbook view takes this into account.

Whether this is the case or whether there is a pattern waiting to be discovered, isn't it true that the world at the quantum level is still governed by mathematically precise laws as it is at the level of general relativity?

The quantum laws are even more precise than the classical laws. Quantum electrodynamics makes some predictions verified to 12 digits of relative accuracy, something no other theory has achieved.
