Quantum mechanics undermines the notion of separability Classical determinism ceases to apply in the microworld. The notion of perfect right-left symmetry of the universe is found to be faulty. The fundamentals of chemistry become fully understood via quantum mechanics. Distance and time intervals are investigated over 40 orders of magnitude. Low temperature physics delivers superconductivity and levitation.
Nuclear physics unleases the bomb and nuclear energy.
Solid state physics delivers the transistor, which paves the way to microchips . High energy physics discovers and explores various families of particles.
