Consideration Quotes - page 12
Many if not most of his decisions are thrust upon the president, out of the blue, by events beyond his control: oil spills, financial panics, pandemics, earthquakes, fires, coups, invasions, underwear bombers, movie-theater shooters, and on and on and on. They don't order themselves neatly for his consideration but come in waves, jumbled on top of each other. "Nothing comes to my desk that is perfectly solvable,” Obama said at one point. "Otherwise, someone else would have solved it. So you wind up dealing with probabilities. Any given decision you make you'll wind up with a 30 to 40 percent chance that it isn't going to work. You have to own that and feel comfortable with the way you made the decision. You can't be paralyzed by the fact that it might not work out.” On top of all of this, after you have made your decision, you need to feign total certainty about it. People being led do not want to think probabilistically.
Barack Obama
The whole science of heat is founded Thermometry and Calorimetry, and when these operations are understood we may proceed to the third step, which is the investigation of those relations between the thermal and the mechanical properties of substances which form the subject of Thermodynamics. The whole of this part of the subject depends on the consideration of the Intrinsic Energy of a system of bodies, as depending on the temperature and physical state, as well as the form, motion, and relative position of these bodies. Of this energy, however, only a part is available for the purpose of producing mechanical work, and though the energy itself is indestructible, the available part is liable to diminution by the action of certain natural processes, such as conduction and radiation of heat, friction, and viscosity. These processes, by which energy is rendered unavailable as a source of work, are classed together under the name of the Dissipation of Energy.
