In literature:

The former rests on the fundamental principle that the quantity of force in the universe is invariable.

In just the same way energy can be measured as a quantity in terms of a fundamental unit.
"Recent Developments in European Thought" by Various
The fundamental principle of his philosophy is that the source of all things is an undefined substance infinite in quantity.

In science:

The trick here lies in recognizing the measurements which yield this fundamental CP-violating quantity.
CP violation in beauty decays
Moreover, it has been possible in some cases to replace calculated quantities with better-determined experimental ones, reducing errors on fundamental parameters such as CKM matrix elements.
Moriond QCD 2007 - Theory Summary
Definitive measurements of ˆq, η/s, and other fundamental quantities require the upgrades and progress in theory discussed in this chapter.
Phases of QCD: Summary of the Rutgers Long Range Plan Town Meeting
Another key aspect of fluid mechanics (and physics in general) is the fundamental notion of the conservation of quantities which is encompassed in the fluidised equations of motion.
A review of wildland fire spread modelling, 1990-present, 1: Physical and quasi-physical models
In particular, the predictive power of the SM and the precision of the electroweak measurements is elucidated by the predictions of the masses of heavy fundamental particles, such as W boson, top quark and Higgs boson, which are contrasted with the direct measurements of these quantities.
Experimental Precision Tests for the Electroweak Standard Model
As the understanding of the strong interaction, and the capability of making more precise theoretical predictions, develops, more and more stringent comparisons of theory and experiment are possible, leading to improved measurements of fundamental quantities such as the strong coupling constant [252, 279].
The NLO multileg working group: summary report
To introduce some fundamental concepts and quantities, we first study the model without any selection.
Evolutionary game dynamics in phenotype space
In cases where considerable theoretical input is required to extract the fundamental quantities, no attempt is made to do so at this stage.
Averages of b-hadron and c-hadron Properties at the End of 2007
Therefore the most precise measurements of these quantities relates to very fundamental questions of our theoretical understanding.
What HERA may provide ?
This would allow the determination of a synthetic error bar in determinations of fundamental quantities like Teff, log g, and metallicity.
A comparison of chemistry and dust cloud formation in ultracool dwarf model atmospheres
This is a fundamental statistical quantity, and other quantities of importance depend naturally on Q.
Quantile pyramids for Bayesian nonparametrics
One may argue that the latter is not a fundamental quantity, but one has to keep in mind that the nuclear moment is mostly determined by the strong interaction.
Testing the Stability of the Fine Structure Constant in the Laboratory
Clustering strength is one of the fundamental properties of a galaxy population, and a key quantity to include in any complete description of a sample.
Understanding Lyman-alpha emitters
The quantities nω and n2ω, for our Type-I phase matched application, are the indices of refraction for o-polarized fundamental radiation and e-polarized second harmonic radiation respectively.
Single barium ion spectroscopy: light shifts, hyperfine structure, and progress on an optical frequency standard and atomic parity violation
As an example, consider such a fundamental quantity as particle multiplicities; in the absence of nontrivial infrared effects, the number of partons that would be mapped to hadrons in a naïve local-parton-hadron-duality picture would tend logarithmically to infinity as the IR cutoff is lowered.
