Unlike its namesake, Quantum Theory makes no attempt to depart
from classical mechanics - it merely diminishes them.
Not exact matches
Hence, panpsychism categorically rejects as a colossal metaphysical error the entire tradition of atomistic materialism
from Democritus to Lucretius to
classical Newtonian
mechanics.
How does
classical mechanics emerge
from quantum
mechanics, and where is the threshold that divides the realms?
According to Dr Frankcombe, «this work demonstrates that these
classical, intuitive ideas of individual electron movements have been the right way to look at chemical reactivity all along, even though they previously had little support
from quantum
mechanics.»
So scientists have tried involving quantum
mechanics as well, because information that is encoded into a quantum system behaves differently
from a
classical system.
However, this «coherence» lasts for only a fraction of a second before the whole system decoheres — a phenomenon that marks the transition
from the realm of quantum to
classical mechanics.
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.
Quantum correlations represent a characteristic trait of quantum
mechanics that in recent years has become a formidable tool for overcoming
classical limits in several fields ranging
from computation and communication to imaging and metrology.
Atomistic and coarse - grained models — ranging
from classical molecular dynamics to quantum
mechanics and the hierarchy of models in between — have provided unprecedented levels of insight into a wide range of chemical, biological, and soft matter and solid - state phenomena.
How far it departs
from the cyclical expectations of
classical mechanics is unknowable — but depart it does.
