The phrase "a classical description" is correct and usable in written English.
It can be used when referring to a traditional or established way of explaining or depicting something, often in a scientific or artistic context.
Example: "In physics, a classical description of motion is based on Newton's laws."
Alternatives: "a traditional explanation" or "a conventional portrayal."
And when we say bigger, remember this is not a classical description we're talking about.
The process of transformation from a classical description to an equation of quantum mechanics, and from the solution of this equation to the probability that a specified experiment will yield a specified observation, is not to be thought of as a temporary expedient pending the development of a better theory.
As we have mentioned already, there are cases in which a classical description is not a good description of a phenomenon, even if the phenomenon involves macroscopic systems.
Hence if one does not argue for spontanuous collapse of the wave function, hidden variables, or many worlds, one needs to supplement quantum mechanics with a classical description of measuring instruments in terms of clocks and rods.
Thus, there is a sense in which one can recover at least one dynamical aspect of a classical description, a trajectory of sorts: from the source to either slit (with a certain probability), and from the slit to the screen (also with a certain probability).
While CRE at column i is given by the Kullback-Liebler distance between the corresponding ith columns A classical description of entropy does not take into consideration the absence of data points which are gaps in the case of a multiple alignment column.
"I" am an object, such as the Earth, a cat, etc. "I" is defined at a particular time by a complete (classical) description of the state of my body and of my brain.
This way, quantum field theory provides formal elements from which a standard classical description of brain activity can be inferred, and this is its main role in the model.
This is achieved by converting from a statistical thermodynamic description to a classical thermodynamic description resulting in a reduction of model parameters from more than 100 to a total of only 26.
Structures retrieved from the Protein Data Bank included parallel and anti-parallel variants of two, three and four-stranded coiled coils, one example of a parallel pentamer and a small number of structures that extend the classical description of a coiled coil.
This is what Scheibe (1973) has called the "buffer postulate" because it prevents the quantum from penetrating into the classical description: A phenomenon must always be described in classical terms; Planck's constant does not occur in this description.
