Disappear Quotes (12 quotes)


Courage and perseverance have a magical talisman, before which difficulties disappear and obstacles vanish into air.
From An Oration, Delivered at Plymouth, December 22, 1802, at the Anniversary Commemoration of the First Landing of our Ancestors at that Place (1802), 13.

Curves that have no tangents are the rule. … Those who hear of curves without tangents, or of functions without derivatives, often think at first that Nature presents no such complications. … The contrary however is true. … Consider, for instance, one of the white flakes that are obtained by salting a solution of soap. At a distance its contour may appear sharply defined, but as we draw nearer its sharpness disappears. The eye can no longer draw a tangent at any point. … The use of a magnifying glass or microscope leaves us just as uncertain, for fresh irregularities appear every time we increase the magnification. … An essential characteristic of our flake … is that we suspect … that any scale involves details that absolutely prohibit the fixing of a tangent.
(1906). As quoted “in free translation” in Benoit B. Mandelbrot, The Fractal Geometry of Nature (1977, 1983), 7.

Every 10 years, an area the size of Britain disappears under a jungle of concrete.
As quoted from BBC TV series, Planet Earth II in Joe Shute, 'David Attenborough at 90: ‘I think about my mortality every day’', The Telegraph (29 Oct 2016).

I am concerned about the air we breathe and the water we drink. If overfishing continues, if pollution continues, many of these species will disappear off the face of the earth.

If all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago. If insects were to vanish, the environment would collapse into chaos.
In Rosemarie Jarski, Words From The Wise (2007), 269. [Contact webmaster if you know the primary print source.]

If the bee disappeared off the face of the earth, man would only have four years left to live.
This is regarded as probably NOT a quote by Einstein.
This is something Einstein most probably did NOT say! Since scholarly search for this quote has thus far found no reliable source for it, it must at least be classed as undetermined. Furthermore, since its first appearance is 40 years after his death, in dubious context for authenticity, it deserves to be regarded as spurious. See snopes.com article. It is added here to serve as a caution to the reader.

If we [humans] disappeared overnight, the world would probably be better off.
Interview about Life In The Undergrowth (book and TV series on insects), The Daily Telegraph (12 Nov 2005).

Moreover I can assure you that the misuse word “national” by our rulers has thoroughly broken me of the habit of national feeling that was pronounced in my case. I would now be willing see Germany disappear as a power and merge into a pacified Europe.
As quoted in Paul Forman and Armin Hermann, 'Sommerfeld, Arnold (Johannes Wilhelm)', Biography in Dictionary of Scientific Biography (1975), Vol. 12, 529. Cited from Armin Herman (ed.), Albert Einstein/Arnold Sommerfeld. Briefwechsel: Sechzig Briefe aus dem goldenen Zeitalter der modernen Physik (1968, German), 114-115.

My dear friend, to be both powerful and fair has always been difficult for mankind. Power and justice have always been seen like day and night; this being the case, when one of them is there the other disappears.
From the play Galileo Galilei (2001) .

Science has found that nothing can disappear without a trace. Nature does not know extinction. All it knows is transformation.
In This Week Magazine (24 Jan 1960), 2. As quoted in Martin A. Recio, From the Threshold of Heaven (2008), 102.
Science quotes on:  |  Conservation Of Energy (22)  |  Evolution (445)  |  Extinction (50)  |  Know (146)  |  Nature (860)  |  Nothing (189)  |  Science (1371)  |  Trace (23)  |  Transformation (40)

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)

When I first ventured into the Gulf of Mexico in the 1950s, the sea appeared to be a blue infinity too large, too wild to be harmed by anything that people could do. I explored powder white beaches, dense marshes, mangrove forests, and miles of sea grass meadows alive with pink sea urchins, tiny shrimps, and seahorses half the size of my little finger. … Then, in mere decades, not millennia, the blue wilderness of my childhood disappeared: biologic change in the space of a lifetime.
From 'My Blue Wilderness', National Geographic Magazine (Oct 2010), 76.

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
