A Quote by Robert Zubrin
Weather systems are natural heat engines, and like all other heat engines, both natural and artificial, they are driven not by temperature per se, but by differences in temperature between one location and another.

This law (regarding the theoretical efficiency of heat engines by Mr. Joule), and the law of the maximum efficiency of heat engines, are particular cases of a general law which regulates all transformation of energy, and is the basis of the Science of Energetics.
The switch from 'steam engines' to 'heat engines' signals the transition from engineering practice to theoretical science.
A rise in body temperature during sulphonamide treatment intensifies the biochemical reaction between drug and pathogen, while at the same time the heat itself injures the heat-sensitive gonococci.
Nature prefers the more probable states to the less probable because in nature processes take place in the direction of greater probability. Heat goes from a body at higher temperature to a body at lower temperature because the state of equal temperature distribution is more probable than a state of unequal temperature distribution.
(On the temperature of water in wells) The reason why the water in wells becomes colder in summer is that the earth is then rarefied by the heat, and releases into the air all the heat-particles it happens to have. So, the more the earth is drained of heat, the colder becomes the moisture that is concealed in the ground. On the other hand, when all the earth condenses and contracts and congeals with the cold, then, of course, as it contracts, it squeezes out into the wells whatever heat it holds.
I remember feeling the temperature change the first time the curtain came up, the difference between the audience temperature and the stage temperature. I'll never forget it.
Deep-frying properly requires you to keep the oil at a precise temperature range depending on the food. If you're frying in more than an inch of oil you really should invest in a deep-fat thermometer so you can monitor the temperature and know when to adjust the heat.
I have come to know the mutability of all human relationships and have learned to insulate myself against both heat and cold so that a temperature balance is fairly well assured.
The hurricanes are following the tropical ocean temperature. The tropical ocean temperature is following the Northern Hemisphere. And it's very hard now to believe that there's anything natural about that.
The first big effects will be farmers that live on the edge. Today's weather, they barely get by. Their kids, a high percentage are malnourished, and so if you impose more variable weather and more heat, you're getting more floods, more droughts, and during the germination time, the high heat, most crops...do poorly when there's more heat.
Our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change. The deadly European heat wave of 2003, the fiery Russian heat wave of 2010 and catastrophic droughts in Texas and Oklahoma last year [2011] can each be attributed to climate change. The odds that natural variability created these extremes are minuscule, vanishingly small. To count on those odds would be like quitting your job and playing the lottery every morning to pay the bills.
Is the mean temperature of the ground in any way influenced by the presence of heat-absorbing gases in the atmosphere?
Geologists and paleo-climatologists know that in the past the Earth's temperature has been substantially warmer than it is today, and that this warming has occurred under purely natural circumstances. Until we can say precisely how much of the current global warming and greenhouse gas increase is the result of this normal temperature cycle, we will not be able to measure how much human activity has added to this natural trend, nor will we be able to predict whether there will be any lasting negative effects.
The difference between "machines" and "engines" is obviously this, that machines need more workmen and greater power to make them take effect, as for instance ballistae and the beams of presses. Engines, on the other hand, accomplish their purpose at the intelligent touch of a single workman...
I am a leader. Leaders always get heat. They're always going against the grain. Jimi Hendrix got heat; Bob Marley got heat; Miles Davis got heat. Every great artist got heat. Heat means you're doing something right.
I am a leader, so leaders always get heat. They're always going against the grain. Jimi Hendrix got heat; Bob Marley got heat; Miles Davis got heat. Every great artist got heat. Heat means you're doing something right.
