One consequence of this quantization is that the classical formula for calculating the electrical resistance of a wire:

The classical formula relating energy to momentum may then be used to give the energy eigenvalues of the system.

Some elements of opera reform, seeking a more 'classical' formula, had begun at the end of the 18th century.

The classical formula for the present value of a series of n fixed monthly payments amount x invested at a monthly interest rate i% is:

The classical formulae for the energy and momentum of electromagnetic radiation can be re-expressed in terms of photon events.

The derivative of is given by a classical derivative formula of Gauss:

"The classical liberal formula had kind of run out," Mr. Peretz said, describing the political mood then.

Recent work on adhesion has shown that these classical formulae need to be modified to take into account molecular attraction, which increases the area of contact.

The classical formula was first to cripple the strong, then crush the weak, and then, later, confront the strong again in one's own good time.

Miscellaneous other modernisations of classical formulae have taken place from time to time.
