A Quote by Antonie van Leeuwenhoek

In rain water, I observed a small red worm and two other kinds of very minute insects; of those of the larger size, I judged that 30,000 together would not equal a coarse sand.

The 4th sort of creatures... which moved through the 3 former sorts, were incredibly small, and so small in my eye that I judged, that if 100 of them lay [stretched out] one by another, they would not equal the length of a grain of course Sand; and according to this estimate, ten hundred thousand of them could not equal the dimensions of a grain of such course Sand. There was discover'd by me a fifth sort, which had near the thickness of the former, but they were almost twice as long. The first time bacteria were observed.

The sand should be neither coarse nor fine but of a middling quality or about the size of the common pop(p)y seed. If the sand is too coarse the mortar will be short or brittle . . . If the sand is too fine the cement will shrink and crack after it has been used.

I have recently observed and stated that the serum of normal people is capable of clumping the red cells of other healthy individuals... As commonly expressed, it can be said that in these cases at least two different kinds of agglutinins exist, one kind in A, the other in B, both together in C. The cells are naturally insensitive to the agglutinins in their own serum.

MAGNITUDE, n. Size [that is] purely relative. If everything in the universe were increased 1,000 diameters nothing would be any larger than it was before, but if one thing remain unchanged all the others would be larger than they had been.

Ambrose Bierce

The totalitarians in the world are very, very small. Only the smallest part of humanity wishes and acts upon the destruction of others. The pluralists are far larger. Those of us who believe in a world where we live together - we're far larger. The problem is we haven't made our case compelling across the world yet.

It is not size that counts in business. Some companies with $500,000 capital net more profits than other companies with $5,000,000. Size is a handicap unless efficiency goes with it.

The 31th of May, I perceived in the same water more of those Animals, as also some that were somewhat bigger. And I imagine, that [ten hundred thousand] of these little Creatures do not equal an ordinary grain of Sand in bigness: And comparing them with a Cheese-mite (which may be seen to move with the naked eye) I make the proportion of one of these small Water-creatures to a Cheese-mite, to be like that of a Bee to a Horse: For, the circumference of one of these little Animals in water, is not so big as the thickness of a hair in a Cheese-mite.

This part of optics, when well understood, shows us how we may make things a very long distance off appear as if placed very close, and large near things appear very small, and how we may make small things placed at a distance appear any size we want, so that it may be possible for us to read the smallest letters at incredible distances, or to count sand, or seed, or any sort or minute objects.

A major puzzle for which nobody has an answer is this: is there some size at which the planets change their nature from water-rich planets like Neptune, to rocky planets like the Earth? We have found two planets that are the size of the Earth in radius, but they are very close to their host star, so water on the surface would evaporate away.

The man who now confronted Gashford, was a squat, thickset personage, with a low, retreating forehead, a coarse shock head of hair, and eyes so small and near together, that his broken nose alone seemed to prevent their meeting and fusing into one of the usual size.

Charles Dickens

So we must lay it down that the association which is a state exists not for the purpose of living together but for the sake of noble actions. Those who contribute most to this kind of association are for that very reason entitled to a larger share in the state than those who, though they may be equal or even superior in free birth and in family, are inferior in the virtue that belongs to a citizen. Similarly they are entitled to a larger share than those who are superior in riches but inferior in virtue.

Aristotle

Two or three girls go to a club and they've worked out that one player is worth 50,000 (128,000), another's worth 30,000 (77,000). That's the reality.

Max Clifford

It is absurd to say that our country can issue $30,000,000 in bonds and not $30,000,000 in currency. Both are promises to pay; but one promise fattens the usurer (banker), and the other helps the people. If the currency issued by the Government were no good, then the bonds issued would be no good either. It is a terrible situation when the Government, to increase the national wealth, must go into debt and submit to ruinous interest charges at the hands of men who control the fictitious values of gold.

Thomas A. Edison

There are two kinds of spiritual law, two kinds of conscience, one in man and another, altogether different, in woman. They do not understand each other; but in practical life the woman is judged by man's law, as though she were not a woman but a man.

There are so many things out there now like these 30-minute workouts. I don't know if they work, but a lot of people have jobs and they don't have time to go to the gym. They can do those little 30-minute workouts they see on TV, or get one of those little portable gyms for their house. I think that's a good start.
