The work of Karplus, Levitt and Warshel is ground - breaking in that they managed to make Newton's
classical physics work side - by - side with the fundamentally different quantum physics.

Classical physics — the kind we know about courtesy of Galileo and Newton — is comparatively easy to understand because we can clearly see it
working all around us: the apple falls from the tree; the earth orbits the sun; the thrown baseball follows an arc that we can predict with an equation.
Theory in science is the conceptual framework within which each science
works, e.g.
classical mechanics, relativity, quantum mechanics, strings are all theories in
physics.
In
classical physics from the spot P we infer the position of atom A. From the spot P, the track PP1, and from knowledge of how the lens
works, we could also know the momentum of the particle.
The GPS system wouldn't
work if
classical physics was used, semiconductors and hence computers, cell phones, Internet, etc wouldn't be possible, lasers wouldn't
work, the list goes on and on.
Measurement is a crucial concept in quantum mechanics, because it doesn't
work like the traditional measurements of
classical physics.
Rennie: I mean there has been this conflict going back early into the time when the history of quantum mechanics, that it didn't sit well with the more
classical physics universe that Einstein was
working with when he was developing his relativity theories.
Magnetism at the atomic level is driven by quantum mechanics — a fact that has shaken up
classical physics calculations and called for increasingly complex, first - principle calculations, or calculations
working forward from fundamental
physics equations rather than relying on assumptions that reduce computational workload.
When
classical physics predicted a certain spectrum from a black body, there was no guess
work, the spectrum didn't match predictions.
