Invisible Quotes (10 quotes)

'Tis a short sight to limit our faith in laws to those of gravity, of chemistry, of botany, and so forth. Those laws do not stop where our eyes lose them, but push the same geometry and chemistry up into the invisible plane of social and rational life, so that, look where we will, in a boy's game, or in the strifes of races, a perfect reaction, a perpetual judgment keeps watch and ward.
From 'Worship', The Conduct of Life (1860) collected in The Complete Works of Ralph Waldo Emerson (1866), Vol.2, 401.

All cell biologists are condemned to suffer an incurable secret sorrow: the size of the objects of their passion. … But those of us enamored of the cell must resign ourselves to the perverse, lonely fascination of a human being for things invisible to the naked human eye.
Opening sentence from The Center of Life: A Natural History of the Cell (1977, 1978), 5.

All human affairs follow nature's great analogue, the growth of vegetation. There are three periods of growth in every plant. The first, and slowest, is the invisible growth by the root; the second and much accelerated is the visible growth by the stem; but when root and stem have gathered their forces, there comes the third period, in which the plant quickly flashes into blossom and rushes into fruit.
The beginnings of moral enterprises in this world are never to be measured by any apparent growth. ... At length comes the sudden ripeness and the full success, and he who is called in at the final moment deems this success his own. He is but the reaper and not the labourer. Other men sowed and tilled and he but enters into their labours.
Life Thoughts (1858), 20.

Everything is becoming science fiction; From the margins of an almost invisible literature has sprung the intact reality of the 20th century
'Fictions of Every Kind'. In Books and Bookmen (Feb 1971).

I will insist particularly upon the following fact, which seems to me quite important and beyond the phenomena which one could expect to observe: The same [double sulfate of uranium and potassium] crystalline crusts, arranged the same way [as reported to the French academy on 24 Feb 1896] with respect to the photographic plates, in the same conditions and through the same screens, but sheltered from the excitation of incident rays and kept in darkness, still produce the same photographic images ... [when kept from 26 Feb 1896] in the darkness of a bureau drawer. ... I developed the photographic plates on the 1st of March, expecting to find the images very weak. Instead the silhouettes appeared with great intensity.
It is important to observe that it appears this phenomenon must not be attributed to the luminous radiation emitted by phosphorescence ... One hypothesis which presents itself to the mind naturally enough would be to suppose that these rays, whose effects have a great similarity to the effects produced by the rays studied by M. Lenard and M. Rφntgen, are invisible rays ...
[Having eliminated phosphorescence as a cause, he has further revealed the effect of the as yet unknown radioactivity.]
Read at French Academy of Science (2 Mar 1896). In Comptes Rendus (1896), 122, 501. As translated by Carmen Giunta on the Classic Chemistry web site.

In space there are countless constellations, suns and planets; we see only the suns because they give light; the planets remain invisible, for they are small and dark. There are also numberless earths circling around their suns, no worse and no less than this globe of ours. For no reasonable mind can assume that heavenly bodies that may be far more magnificent than ours would not bear upon them creatures similar or even superior to those upon our human earth.
As quoted in Dave Goldberg, The Universe in the Rearview Mirror: How Hidden Symmetries Shape Reality (2013), 74.

Science is not the enemy of humanity but one of the deepest expressions of the human desire to realize that vision of infinite knowledge. Science shows us that the visible world is neither matter nor spirit; the visible world is the invisible organization of energy.
The Cosmic Code (1982), 348.
Science quotes on:  |  Avoid (8)  |  Desire (46)  |  Enemy (26)  |  Energy (103)  |  Expression (44)  |  Humanity (46)  |  Knowledge (679)  |  Matter (135)  |  Organization (51)  |  Realize (5)  |  Respect (24)  |  Science (875)  |  Spirit (52)  |  Visible (3)  |  Vision (21)  |  World (231)

The traditional boundaries between various fields of science are rapidly disappearing and what is more important science does not know any national borders. The scientists of the world are forming an invisible network with a very free flow of scientific information - a freedom accepted by the countries of the world irrespective of political systems or religions. ... Great care must be taken that the scientific network is utilized only for scientific purposes - if it gets involved in political questions it loses its special status and utility as a nonpolitical force for development.
Banquet speech accepting Nobel Prize in Physiology or Medicine (10 Dec 1982). In Wilhelm Odelberg (editor) Les Prix Nobel. The Nobel Prizes 1982 (1983)

This therefore is Mathematics:
She reminds you of the invisible forms of the soul;
She gives life to her own discoveries;
She awakens the mind and purifies the intellect;
She brings light to our intrinsic ideas;
She abolishes oblivion and ignorance which are ours by birth...
Proclus
Quoted in Benjamin Franklin Finkel, Mathematical Association of America, The American Mathematical Monthly (1947), Vol. 54, 425.

What we see in history is not a transformation, a passing of one race into another, but entirely new and perfect creations, which the ever-youthful productivity of nature sends forth from the invisible realm of Hades.
Translated from Das Besdδndige in den Menschenrassen und die Spielweite ihrer Verδnderlichkeit (1868), 26. As cited, with quotation marks, in Houston Stewart Chamberlain, The Foundations of the Nineteenth Century (1911), Vol. 1, 272. Note: Webmaster cannot find and recognize the original quote in German in the Bastian source book, and especially cannot find it on page 26.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
