Moisture Quotes (10 quotes)


Question: State what are the conditions favourable for the formation of dew. Describe an instrument for determining the dew point, and the method of using it.
Answer: This is easily proved from question 1. A body of gas as it ascends expands, cools, and deposits moisture; so if you walk up a hill the body of gas inside you expands, gives its heat to you, and deposits its moisture in the form of dew or common sweat. Hence these are the favourable conditions; and moreover it explains why you get warm by ascending a hill, in opposition to the well-known law of the Conservation of Energy.
Genuine student answer* to an Acoustics, Light and Heat paper (1880), Science and Art Department, South Kensington, London, collected by Prof. Oliver Lodge. Quoted in Henry B. Wheatley, Literary Blunders (1893), 179, Question 12. (*From a collection in which Answers are not given verbatim et literatim, and some instances may combine several students' blunders.)

[On the propulsive force of rockets] One part of fire takes up as much space as ten parts of air, and one part of air takes up the space of ten parts of water, and one part of water as much as ten parts of earth. Now powder is earth, consisting of the four elementary principles, and when the sulfur conducts the fire into the dryest part of the powder, fire, and air increase … the other elements also gird themselves for battle with each other and the rage of battle is changed by their heat and moisture into a strong wind.
In De La Pirotechnia (1540). From the 1943 English translation, as given in Willy Ley, Rockets: The Future of Travel Beyond the Stratosphere (1944), 64. Though Birinuccio provided the first insight into what propels a rocket, the “strong wind” blowing downward, he did not explain why that should cause the rocket to rise upward, as Issac Newton would do with his Third Law of Motion, nearly a century and a half later.

If one of these elements, heat, becomes predominant in any body whatsoever, it destroys and dissolves all the others with its violence. …Again if too much moisture enters the channels of a body, and thus introduces disproportion, the other elements, adulterated by the liquid, are impaired, and the virtues of the mixture dissolved. This defect, in turn, may arise from the cooling properties of moist winds and breezes blowing upon the body. In the same way, increase or diminution of the proportion of air or of the earthy which is natural to the body may enfeeble the other elements.
Vitruvius
In De Architectura, Book 1, Chap 4, Sec. 6. As translated in Morris Hicky Morgan (trans.), Vitruvius: The Ten Books on Architecture (1914), 18-19.

It is fashionable nowadays to talk about the endless riches of the sea. The ocean is regarded as a sort of bargain basement, but I don’t agree with that estimate. People don’t realize that water in the liquid state is very rare in the universe. Away from earth it is usually a gas. This moisture is a blessed treasure, and it is our basic duty, if we don’t want to commit suicide, to preserve it.
As quoted by Nancy Hicks in 'Cousteau’s Philosophy of the Sea Helps Him Get Another Medal', New York Times (25 Oct 1970), 54.

It was a dark and stormy night, so R. H. Bing volunteered to drive some stranded mathematicians from the fogged-in Madison airport to Chicago. Freezing rain pelted the windscreen and iced the roadway as Bing drove on—concentrating deeply on the mathematical theorem he was explaining. Soon the windshield was fogged from the energetic explanation. The passengers too had beaded brows, but their sweat arose from fear. As the mathematical description got brighter, the visibility got dimmer. Finally, the conferees felt a trace of hope for their survival when Bing reached forward—apparently to wipe off the moisture from the windshield. Their hope turned to horror when, instead, Bing drew a figure with his finger on the foggy pane and continued his proof—embellishing the illustration with arrows and helpful labels as needed for the demonstration.
In 'R. H. Bing', Biographical Memoirs: National Academy of Sciences (2002), 49. Anecdote based on the recollections of Bing's colleagues, Steve Armentrout and C. E. Burgess. The narrative was given in a memorial tribute at the University of Texas at Austin.

Many animals even now spring out of the soil,
Coalescing from the rains and the heat of the sun.
Small wonder, then, if more and bigger creatures,
Full-formed, arose from the new young earth and sky.
The breed, for instance, of the dappled birds
Shucked off their eggshells in the springtime, as
Crickets in summer will slip their slight cocoons
All by themselves, and search for food and life.
Earth gave you, then, the first of mortal kinds,
For all the fields were soaked with warmth and moisture.
On the Nature of Things, trans. Anthony M. Esolen (1995), Book 5, lines 794-803, 181.

The handling of our forests as a continuous, renewable resource means permanent employment and stability to our country life. The forests are also needed for mitigating extreme climatic fluctuations, holding the soil on the slopes, retaining the moisture in the ground, and controlling the equable flow of water in our streams.
From 'A Presidential Statement on Receipt of the Award of the Schlich Forestry Medal' (29 Jan 1935) in Public Papers of the Presidents of the United States: F.D. Roosevelt, 1935, Volume 4 (1938), 65. Roosevelt was awarded the medal by the Society of American Foresters. This quote continues with the line “The forests are the ‘lungs’ of our land….”

The world's forests need to be seen for what they are—giant global utilities, providing essential public services to humanity on a vast scale. They store carbon, which is lost to the atmosphere when they burn, increasing global warming. The life they support cleans the atmosphere of pollutants and feeds it with moisture. They act as a natural thermostat, helping to regulate our climate and sustain the lives of 1.4 billion of the poorest people on this Earth. And they do these things to a degree that is all but impossible to imagine.
Speech (25 Oct 2007) at the World Wildlife Fund gala dinner, Hampton Court Palace, announcing the Prince's Rainforests Project. On the Prince of Wales website.

There were taken apples, and … closed up in wax. … After a month's space, the apple inclosed in was was as green and fresh as the first putting in, and the kernals continued white. The cause is, for that all exclusion of open air, which is ever predatory, maintaineth the body in its first freshness and moisture.
[In the U.S., since the 1920s, (to replace the fruit's original wax coating that is lost in the cleaning process after harvesting), natural waxes, such as carnauba wax, are applied in an extremely thin coating, to reduce loss of moisture and maintain crispness and appearance.]

While all bodies are composed of the four elements, that is, of heat, moisture, the earthy, and air, yet there are mixtures according to natural temperament which make up the natures of all the different animals of the world, each after its kind.
Vitruvius
In De Architectura, Book 1, Chap 4, Sec. 5. As translated in Morris Hicky Morgan (trans.), Vitruvius: The Ten Books on Architecture (1914), 16.

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
