In science:

But in typical experiments, including the one by Brida et al., the quantity η so defined is rather small with the consequence that the inequality (7) is very well fulfilled, thus making the tests of the LH V 1 familly vs.quantum mechanics almost impossible.
Analysis of a recent experimental test of Bell inequalities violating quantum predictions
Unfortunately, Theorem 4 tells us that this is impossible with our deconvolution framework, since the p(n) , which are the quantities we can find through deconvolution, have no dependency to them.
Asymptotic Behaviour of Random Vandermonde Matrices with Entries on the Unit Circle
The UUB depending on such uncontrollable quantities as weights makes it impossible to provide practically valuable guarantees of the closed-loop system performance.
Feasibility of random basis function approximators for modeling and control
Since all the observable quantities related to background evolution, are constructed out of H (z ), it is practically impossible to distinguish these models from ΛCDM using the current data.
The thawing dark energy dynamics: Can we detect it?
As we will see, this diffusion approximation has many consequences for questions of practical importance, as several quantities of interest have exact formulae in this approximation (while in the discrete model, these quantities would often be hard or impossible to compute exactly).
Recent progress in coalescent theory
What is more disturbing, is the fact that the quantities Ψ and t∗ are more or less impossible to compute in an explicit form, and this makes Lemma 3.4 not a very good starting point for further investigations.
Hopfield models as generalized random mean field models
For “radiation” fields (examples of which are easy to write down explicitly), both of these quantities vanish identically, so such a frame is impossible for nonzero radiation fields.
Comment on Phys. Rev. D 60 084017 "Classical self-force" by F. Rohrlich
Remark 2 As we can see, it is impossible to have any information about the real behavior of the quantities since they depend on several integration constants.
About Bianchi I with VSL
Since it is impossible to either measure or calculate states beyond LO with two and only two jets, due to soft radiation, one can form quantities from the leading two jets, and ignore other energy in the event.
QCD Tests in Proton-Antiproton Collisions
However, in view of the absence of information about the NNLO perturbative corrections to this quantity, it is impossible at present to check the advantages of this choice self-consistently.
Radiative QCD Corrections: A Personal Outlook
This term makes it impossible to make an exact, local calculation of these quantities in terms of their initial values (Kofman & Pogosyan  ).
Further, carrying out any meaningful analysis while these quantities are sub ject to changes in time is impossible.
Comparison of Field Theory Models of Interest Rates with Market Data
The constants µ and β are determined by Eqs. (1) and (2), though it is generally impossible to find an exact analytic expression for them in terms of the conserved quantities ρ and ρu; rather one must solve for them numerically or perform a Taylor expansion in Mach number.
Galilean-Invariant Lattice-Boltzmann Models with H-Theorem
The first condition is impossible unless 4The introduction of this quantity is suggested by the procedure followed by Silva & Navaza (1981) and Navaza & Navaza (1992).

At present, all this make impossible to directly confront theory and experiments in K → 2π , especially in delicate quantities such as ε (cid:48)/ε .
