" In response to an enquiry about the same sermon from the botanist Henry Nicholas Ridley, Darwin stated that " Dr Pusey was mistaken in imagining that I wrote the Origin with any relation whatever to Theology ", and added that " many years ago when I was collecting facts for the Origin, my belief in what is called a personal God was as firm as that of Dr Pusey himself, & as to the eternity of matter I have never troubled myself about such insoluble questions .— Dr Pusey's attack will be as powerless to retard by a day the belief in evolution as were the virulent attacks made by divines fifty years ago against Geology, & the still older ones of the Catholic church against Galileo ".

She distributed clothes and supplied pregnant women, who had to sleep on the ground, with mattresses, but she could not forgive what she called Crass male ignorance, helplessness and muddling … I rub as much salt into the sore places in their minds … because it is good for them ; but I can't help melting a little when they are very humble and confess that the whole thing is a grievous and gigantic blunder and presents almost insoluble problems, and they don't know how to face it …

Carbon printing is based on the fact that gelatin, when sensitized to light by a dichromate, is hardened and made insoluble in water when exposed to ultraviolet light.

Raoult's law assumes that a component contributes to the total vapor pressure of the mixture in proportion to its percentage of the mixture and its vapor pressure when pure, or succinctly: partial pressure equals mole fraction multiplied by vapor pressure when pure.

He admits that " a large fraction his audience seems to be those who are fascinated by technology ", but when it was suggested that his work " has inspired many students to begin careers in computing and artificial intelligence " he replied that he was pleased about that, but that he himself has " no interest in computers.

when written as a fraction x = p / q in lowest terms ( i. e., the greatest common divisor of p and q is 1 ), satisfies

In the above example, when written out in fraction form, the units of grams form a multiplicative identity, which is equivalent to one ( g / g = 1 ), with the resulting amount of moles ( the unit that was needed ), is shown in the following equation,

However, mass fraction may have little to do with the costs of a rocket, as the costs of fuel are very small when compared to the costs of the engineering program as a whole.

For aqueous solutions, when determining the mole fraction of water, it is necessary to take into account the ionisation of salts.

There are anecdotal objections to the use of metric units in carpentry and the building trades, on the basis that it is easier to remember an integer number of inches plus a fraction than a measurement in millimeters, or that inch measurements are more suitable when distances are frequently divided by two.

The conductivity of the semiconductor changed only by a small fraction of the expected amount when the field was applied, which John Bardeen ( another member of Shockley's division ) suggested was due to the existence of energy states for electrons on the surface of the semiconductor.

Therefore, the 10 / 90 or 20 / 80 knife-edge width is a useful metric when the user wishes to be sure that the width encompasses a fixed fraction of total beam power.

But it fails spectacularly as velocities become some substantial fraction of the speed of light and when interactions at the atomic scale are studied.

Since the notes ring for some significant fraction of a second when struck with the damper pad up, and ringing bars do not stop ringing immediately when contacted by the pad, a technique called " after pedaling " is necessary.

For this reason, a constant relative humidity (%) with different temperatures implies that when it's hotter, a higher fraction of the air is water vapor than when it's cooler.

Thus, intuitively we could interpret the fraction of as representing the ratio of the labor one has to perform when going from a randomly chosen configuration to another randomly chosen configuration, relative to the difficulty of having to cross the " most difficult " path of length which involves moving all the disks from one peg to another.

This is because the rear wheel can only transfer a fraction of the stopping power due to the weight transfer to the front that occurs when braking.

Costello took the opportunity to reconfirm his beliefs in Catholicism on 12 April 1951, in his speech on Dr. Browne's resignation: " I have no hesitation in saying that we, as a Government, representing a people, the overwhelming majority of whom are of the one faith, who have a special position in the Constitution, when we are given advice or warnings by the authoritative people in the Catholic Church, on matters strictly confined to faith and morals, so long as I am here — and I am sure I speak for my colleagues — will give to their directions, given within that scope — and I have no doubt that they do not desire in the slightest to go one fraction of an inch outside the sphere of faith and morals — our complete obedience and allegiance.

In general, when comparing the quantities of a two-quantity ratio, this can be expressed as a fraction derived from the ratio.

On February 1, 1877, when Quitman County was created, Panola surrendered a small fraction of its southwestern area to assist in forming that county, which reduced Panola from an area of to its present land surface of.
