Coolness and absence of heat and haste indicate fine qualities.
When summer opens, I see how fast it matures, and fear it will be short; but after the heats of July and August, I am reconciled, like one who has had his swing, to the cool of autumn.
But see, the shepherds shun the noonday heat, The lowing herds to murmuring brooks retreat, To closer shades the panting flocks remove; Ye gods! And is there no relief for love?
O thou who passest through our valleys in Thy strength, curb thy fierce steeds, allay the heat That flames from their large nostrils! Thou, O Summer, Oft pitchest here thy golden tent, and oft Beneath our oaks hast slept, while we beheld With joy thy ruddy limbs and flourishing hair.
Did he so often lodge in open field, In winter's cold and summer's parching heat, To conquer France, his true inheritance?
Nowadays men cannot love seven night but they must have all their desires: that love may not endure by reason; for where they be soon accorded and hasty, heat soon it cooleth. Right so fareth love nowadays, soon hot soon cold: this is no stability. But the old love was not so.
Today we no longer ask what really goes on in an atom; we ask what is likely to be observed-and with what likelihood-when we subject atoms to any specified influences such as light or heat, magnetic fields or electric currents.
[Henry Cavendish] fixed the weight of the earth; he established the proportions of the constituents of the air; he occupied himself with the quantitative study of the laws of heat; and lastly, he demonstrated the nature of water and determined its volumetric composition. Earth, air, fire, and water-each and all came within the range of his observations.
A star is drawing on some vast reservoir of energy by means unknown to us. This reservoir can scarcely be other than the subatomic energy which, it is known exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service. The store is well nigh inexhaustible, if only it could be tapped. There is sufficient in the Sun to maintain its output of heat for 15 billion years.
The fundamental laws of the universe which correspond to the two fundamental theorems of the mechanical theory of heat. 1. The energy of the universe is constant. 2. The entropy of the universe tends to a maximum.
For the first time there was constructed with this machine [locomotive engine] a self-acting mechanism in which the interplay of forces took shape transparently enough to discern the connection between the heat generated and the motion produced. The great puzzle of the vital force was also immediately solved for the physiologist in that it became evident that it is more than a mere poetic comparison when one conceives of the coal as the food of the locomotive and the combustion as the basis for its life.
The physiological combustion theory takes as its starting point the fundamental principle that the amount of heat that arises from the combustion of a given substance is an invariable quantity-i.e., one independent of the circumstances accompanying the combustion-from which it is more specifically concluded that the chemical effect of the combustible materials undergoes no quantitative change even as a result of the vital process, or that the living organism, with all its mysteries and marvels, is not capable of generating heat out of nothing.
Nothing is sudden in nature: whereas the slightest storms are forecasted several days in advance, the destruction of the world must have been announced several years beforehand by heat waves, by winds, by meteorites, in short, by an infinity of phenomena.
How did Biot arrive at the partial differential equation? [the heat conduction equation] . . . Perhaps Laplace gave Biot the equation and left him to sink or swim for a few years in trying to derive it. That would have been merely an instance of the way great mathematicians since the very beginnings of mathematical research have effortlessly maintained their superiority over ordinary mortals.
As for our pupils talk, let his virtue and his sense of right and wrong shine through it and have no guide but reason. Make him understand that confessing an error which he discovers in his own argument even when he alone has noticed it is an act of justice and integrity, which are the main qualities he pursues; stubbornness and rancour are vulgar qualities, visible in common souls whereas to think again, to change one's mind and to give up a bad case on the heat of the argument are rare qualities showing strength and wisdom.
A lot of people don't realize that about 98 percent of the running I put in is anything but glamorous: 2 percent joyful participation, 98 percent dedication! It's a tough formula. Getting out in the forest in the biting cold and the flattening heat, and putting in kilometer after kilometer.
As a magnifying glass concentrates the rays of the sun into a little burning knot of heat that can set fire to a dry leaf or a piece of paper, so the mystery of Christ in the Gospel concentrates the rays of God's light and fire to a point that sets fire to the spirit of man. ... Through the glass of His Incarnation He concentrates the rays of His Divine Truth and Love upon us so that we feel the burn, and all mystical experience is communicated to men through the Man Christ.
Fear no more the heat o' th' sun Nor the furious winters' rages; Thou thy worldly task hast done, Home art gone, and ta'en thy wages. Golden lads and girls all must, As chimney-sweepers, come to dust.
He will always know as we know now that in the heat of battle he did not fail when mateship and duty called.
The laws of light and of heat translate each other;-so do the laws of sound and colour; and so galvanism, electricity and magnetism are varied forms of this selfsame energy.
We are quite ignorant of the condition of energy in bodies generally. We know how much gas goes in, and how much comes out, and know whether at entrance and exit it is in the form of heat or of work. That is all.
...Was it because a lot of the heat went into melting Arctic sea ice or parts of Greenland and Antarctica, and other glaciers? Was it because the heat was buried in the ocean and sequestered, perhaps well below the surface?...Perhaps all of these things are going on?
There is good evidence that last year's European heat wave was influenced by global warming. It resulted in 26,000 premature deaths and cost $13.5bn.
Winter regularly takes many more lives than any heat wave: 25,000 to 50,000 each year die in Britain from excess cold. Across Europe, there are six times more cold-related deaths than heat-related deaths...by 2050...Warmer temperatures will save 1.4 million lives each year.
Heat may be considered, either in respect of its quantity, or of its intensity. Thus two lbs. of water, equally heated, must contain double the quantity that one of them does, though the thermometer applied to them separately, or together, stands at precisely the same point, because it requires double the time to heat two lbs. as it does to heat one.
