"Differential" Quotes from Famous Books
 ... smoothed their surfaces. That is to say in general terms, the actions of environing agencies, so far as they have operated indiscriminately, have produced in the stones a certain unity of character; at the same time that they have, by their differential effects, separated them: the larger ones having withstood certain violent actions which the smaller ...

... specimens. Otherwise we find that the characters mentioned above differentiate canicaudus from its nearest relatives, Microtus montanus canescens to the northward, M. m. nanus to the eastward, and M. m. montanus to the southward. In canicaudus we have noted one additional differential character; the interpterygoid space is acuminate anteriorly. In this feature and in each of the other features mentioned above, intergradation with Microtus montanus nanus is seen in the specimens from Hood River and Wapinitia. In the specimens from Hood ...

... much more than the individual. We shall take it for granted that British and Irish products and manufactures enjoy a preference on import into the colonies, over imports from foreign countries, of at least five per cent, resulting from differential duties in favour of the parent state: it may be more, and we believe it will be found more; but such is the preference. This profit must be all to the account of the British exporter; for it is not received by the colonial custom-house, ...

Scientific God, you observe, differing from the unscientific one, in that the purest in heart cannot see—nor the softest in heart feel—this spacious Deity—a Medium, pervading space—"the office of which" (italics all mine) "appears to be to degrade and ultimately extinguish, all differential motion. It has been well pointed out by Thomson, that, looked at in this light, the universe is a system that had a beginning and must have an end, for a process of degradation cannot be eternal.

... some of the apparently unaccountable facts in savage society, where we are frequently encountered by a comparatively high degree of culture associated with a cruel and debasing system of rites and practices which belong to the lowest savagery. Dr. Haddon has usefully suggested the term "differential evolution" for this phenomenon in the culture history of man,[310] and as I find myself in entire agreement with this distinguished anthropologist as to the facts[311] which call for a special terminology, I gladly adopt ...

If one of them only has this differentia, then this one is composite and is not ...

The more copious flow in the better conductor was exactly counterbalanced ...

When occurring in the seeds of the variety they betray themselves as soon as the differential characters are displayed.

Quite the contrary effect results from the admixture of hybrids with the seeds of the species itself. Here no difference will show itself, ...

In the struggle between the two, conscience was as usual defeated. The Chancellor, according to the practice which has overridden the Act of Union budgets for Great Britain, ...
