“The effects of heat are subject to constant laws which cannot be discovered without the aid of mathematical analysis. The object of the theory is to demonstrate these laws; it reduces all physical researches on the propagation of heat, to problems of the integral calculus, whose elements are given by experiment. No subject has more extensive relations with the progress of industry and the natural sciences; for the action of heat is always present, it influences the processes of the arts, and occurs in all the phenomena of the universe.” ArtProblemActionLawUniverseGivenProcessNaturalProgressInfluenceSubjectsEffectsObjectsTheoryIndustryElementsResearchRelationConstantAidsExperimentsMathematicalAnalysisHeatCalculusNatural SciencePropagationMathematical AnalysisIntegral Calculus Author:Joseph Fourier
“The transition from coal, oil, and gas to wind, solar, and geothermal energy is well under way. In the old economy, energy was produced by burning something - oil, coal, or natural gas - leading to the carbon emissions that have come to define our economy. The new energy economy harnesses the energy in wind, the energy coming from the sun, and heat from within the earth itself.” WayWellsEarthEnergyNaturalEconomySunWindOilBurningHeatGasTransitionCarbonCoalEmissionsHarnessNatural GasOil And GasCarbon EmissionsNew EnergyAlternative EnergyGeothermalGeothermal Energy Author:Lester R.

“In every one of these haunting and hungry poems, Howell draws a map for how to enter the heat and dew of the human being, naked and facing the natural world, desperate to feel.

“Heat is a universal solvent, melting out of things their power of resistance, and sucking away and removing their natural strength with its fiery exhalations so that they grow soft, and hence weak, under its glow.” GrowsNaturalWeakUniversalResistanceHeatMeltingFiery Author:Marcus Vitruvius Pollio
“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.” WorldKindDifferentBodyNaturalAnimalFourAirElementsHeatTemperamentMixturesMoistureDifferent AnimalsFour Elements Author:Marcus Vitruvius Pollio
“Fir : it contains a great deal of air and fire with very little moisture and the earthy, so that, as its natural properties are of the lighter class, it is not heavy. Hence, its consistence being naturally stiff, it does not easily bend under the load, and keeps its straightness when used in the framework. But it contains so much heat that it generates and encourages decay, which spoils it; and it also kindles fire quickly because of the air in its body, which is so open that it takes in fire and so gives out a great flame.” GivingLittlesDoeBodyUsedNaturalDealsClassFireAirPropertyHeavyFlamesHeatLoadDecayFrameworkSpoilLightersKindlesMoistureKindle Fire Author:Marcus Vitruvius Pollio
“It is conceivable that animal life might have the attribute of using the heat of surrounding matter, at its natural temperature, as a source of energy for mechanical effect . . . .The influence of animal or vegetable life on matter is infinitely beyond the range of any scientific enquiry hitherto entered on. Its power of directing the motions of moving particles, in the demonstrated daily miracle of our human free-will, and in the growth of generation after generation of plants from a single seed, are infinitely different from any possible result of the fortuitous concurrence of atoms.” HumansDifferentMatterMightMovingEnergyGrowthNaturalAnimalResultsGenerationsInfluenceEffectsSourceMiraclePlantSeedsRangeHeatFree WillAttributesAtomsVegetablesParticlesTemperatureAnimal LifeEnquiryFortuitousConcurrenceDaily Miracles Author:Lord Kelvin
“If there's horrible flooding in Pakistan or a horrible heat wave in Texas, we're no longer able to call it an act of God, or a natural disaster, or something like that, the way we could have through all of human history until 35 or 40 years ago.” IfsWayYearsHumansAbleNaturalYears AgoWaveDisasterHorribleHeatTexasPakistanHuman HistoryNatural DisasterFloodingHeat Wave Author:Bill McKibben
