Who said: “The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it... That is how we will preserve our planet, commanded to our care by God. That�s what will lend meaning to the creed our fathers once declared.”

Incandescent Quotes (7 quotes)

Gaia is a thin spherical shell of matter that surrounds the incandescent interior; it begins where the crustal rocks meet the magma of the Earth’s hot interior, about 100 miles below the surface, and proceeds another 100 miles outwards through the ocean and air to the even hotter thermosphere at the edge of space. It includes the biosphere and is a dynamic physiological system that has kept our planet fit for life for over three billion years. I call Gaia a physiological system because it appears to have the unconscious goal of regulating the climate and the chemistry at a comfortable state for life. Its goals are not set points but adjustable for whatever is the current environment and adaptable to whatever forms of life it carries.
In The Revenge of Gaia: Earth’s Climate Crisis & The Fate of Humanity (2006, 2007), 19.

Incandescent carbon particles, by the tens of millions, leap free of the log and wave like banners, as flame. Several hundred significantly different chemical reactions are now going on. For example, a carbon atom and four hydrogen atoms, coming out of the breaking cellulose, may lock together and form methane, natural gas. The methane, burning (combining with oxygen), turns into carbon dioxide and water, which also go up the flue. If two carbon atoms happen to come out of the wood with six hydrogen atoms, they are, agglomerately, ethane, which bums to become, also, carbon dioxide and water. Three carbons and eight hydrogens form propane, and propane is there, too, in the fire. Four carbons and ten hydrogens—butane. Five carbons … pentane. Six … hexane. Seven … heptane. Eight carbons and eighteen hydrogens—octane. All these compounds come away in the breaking of the cellulose molecule, and burn, and go up the chimney as carbon dioxide and water. Pentane, hexane, heptane, and octane have a collective name. Logs burning in a fireplace are making and burning gasoline.
In 'Firewood', Pieces of the Frame (1975), 205-206.

It usually takes me from five to seven years to perfect a thing. Some things I have been working on for twenty-five years—and some of them are still unsolved. My average would be about seven years. The incandescent light was the hardest one of all: it took many years not only of concentrated thought but also of world-wide research. The storage battery took eight years. It took even longer to perfect the phonograph.
As quoted from an interview by B.C. Forbes in The American Magazine (Jan 1921), 86.

Once I dipt into the future far as human eye could see,
And I saw the Chief Forecaster, dead as any one can be-
Dead and damned and shut in Hades as a liar from his birth,
With a record of unreason seldom paralleled on earth.
While I looked he reared him solemnly, that incandescent youth,
From the coals that he’s preferred to the advantages of truth.
He cast his eyes about him and above him; then he wrote
On a slab of thin asbestos what I venture here to quote-
For I read it in the rose-light of the everlasting glow:
Cloudy; variable winds, with local showers; cooler; snow.

The star spectra present such varieties that it is difficult to point out any mode of classification. For the present, I divide them into three groups: first, those having many lines and bands and most nearly resembling the sun viz., Capella, β Geminorum, α Orionis, Aldeberan, γ Leonis, Arcturus, and β Pegasi. These are all reddish or golden stars. The second group, of which Sirius is the type, presents spectra wholly unlike that of the sun, and are white stars. The third group, comprising α Virginis, Rigel &c., are also white stars, but show no lines; perhaps they contain no mineral substance or are incandescent without flame.
L.M. Rutherfurd, 'Astronomical Observations with the Spectroscope' (4 Dec 1862), American Journal of Science and Arts (May 1863), 2nd Series, 35, No. 103, 77. His obituarist, Johns K. Rees, wrote (1892) “This paper was the first published work on star spectra.”

The sun is a mass of incandescent gas, a gigantic nuclear furnace,
Where hydrogen is built into helium at a temperature of millions of degrees.
Yo ho, it’s hot, the sun is not a place where we could live.
But here on earth there’d be no life without the light it gives.
We need its light, we need its heat, we need its energy.
Without the sun, without a doubt, there’d be no you and me.
Hy Zaret
From song 'Why Does the Sun Shine? (The Sun Is A Mass Of Incandescent Gas)' on LP record album Space Songs (1961), in the series Ballads for the Age of Science. Music by Louis Singer, and sung by Tom Glazer. Also recorded by the group They Might Be Giants (1998) who followed up with 'Why Does The Sun Really Shine? (The Sun is a Miasma of Incandescent Plasma)' on CD album Here Comes Science (2009), which corrects several scientific inaccuracies in the lyrics

When it is considered that this light, when obtained with mercury gas, has an efficiency at least eight times as great as that obtained by an ordinary incandescent lamp, it will be appreciated that it has its use in places where lack of red is not important, for the economy of operation will much more than compensate for the somewhat unnatural color given to illuminated objects.
'Electric Gas Lamps and Gas Electrical Resistance Phenomena', a paper read at the 150th AIEE meeting 3 Jan 1902. In Transactions of the American Institute of Electrical Engineers (1902), 61.

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
