  • Interesting fact: People are marrying younger today than they did before the turn of the century. In the United States, in 1890, the average age of men at their first marriage was twenty-six years, compared with twenty-three today. For women, the corresponding figures are twenty-two then and just under twenty-one now.
    • n comparator An apparatus for making comparisons; especially, an instrument for comparing the lengths of nearly equal bars, either from end to end or between lines engraved upon them. The usual optical comparator has two microscopes, firmly attached to a bar or something of that sort, with their focal planes coincident and furnished with filar micrometers, whose screws lie virtually in one right line. There is also a carriage moving at right angles to the screws, so as to bring first one bar and then another under the microscopes. In Saxton's comparator a beam of light is caused to fall on a mirror delicately supported on its axis, round which a very fine chain is wound, the other end being attached to a lever provided with a spring in such a way that the mirror is turned one way or the other as the bar contracts or expands, or is replaced by a shorter or longer bar. The mirror throws the beam upon a large scale at some distance, where it indicates by a large movement the very minute movements of the mirror. One form of color-comparator employs a glass prism, which may be filled with a colored liquid, and a series of glass tubes containing colored solutions of known tints and shades.
    • n comparator A vessel in which liquid is kept rapidly stirred and at a uniform constant temperature so that thermometers immersed in it must all be maintained at the same temperature. Simultaneous readings of the secondary thermometers and the standard are made, and the corrections to the former are thus determined for a wide range of temperatures.

In science:

Practically, we have to measure fluxes within bounded spectral bands, and in order to compare objects at different redshifts we will do our best to compare the same restframe bands which implies measuring high-redshift objects through redder (observer) bands than nearby objects.
The expansion of the universe observed with supernovae
One set of tests compares properties of nearby and distant samples, and the other set compares properties of events at similar redshifts in different environments, i.e. different stellar ages.
The expansion of the universe observed with supernovae
The KS test shows that distributions of fX /fR ratios are consistent with having been drawn from the same parent population (KS probability 0.94 when comparing ω Cen CV candidates to the 11 brightest candidates in NGC 6397, and 0.71 when comparing to all NGC 6397 candidates).

Also, M ∪ {c} is a chain: if z ∈ M, then z and c are comparable, for either z < x(cid:48) (in which case z < c), or z > y (cid:48) (in which case z > c), or z ∈ [x(cid:48), y (cid:48) ] (in which case z ∈ M (cid:48), hence z ∈ C, and z and c are again comparable as elements of the chain C ).
Pruning a poset with veins
In part B, the frequency of the rotating bias field, ωrot, is chosen to be low compared with the frequencies of transitions between different magnetic substates but large compared with the effective radial trap frequency.

This greatly increases the period of the LFG, to M P − M Q for suitably chosen P, Q and M, 27 compared to approximately M 2P for a comparable LFG using subtraction.

Thus, it is natural to smooth ρc (µ, ν ) by integrating over intervals δµ and δν large compared to O(N −1 ) but small compared to O(N 0 ) centered around µ and ν respectively.
Correlation Functions in Disordered Systems
Note that the advantage of having a readily understandable scale in your fit (θc ) is also a disadvantage when it comes to comparing experiments, since values of C0 for different (arbitrary) θc cannot be directly compared.
Quoting Experimental Information
At very low fields where the vortices are far apart compared to the magnetic penetration length there is also an amorphous glass phase due to the vortex-vortex interactions becoming small compared to the random pinning; this is indicated as “reentrant glass”.
