Bekenstein Entropy Quotes & Sayings

Two observations take us across the finish line. The Second Law ensures that entropy increases throughout the entire process, and so the information hidden within the hard drives, Kindles, old-fashioned paper books, and everything else you packed into the region is less than that hidden in the black hole. From the results of Bekenstein and Hawking, we know that the black hole's hidden information content is given by the area of its event horizon. Moreover, because you were careful not to overspill the original region of space, the black hole's event horizon coincides with the region's boundary, so the black hole's entropy equals the area of this surrounding surface. We thus learn an important lesson. The amount of information contained within a region of space, stored in any objects of any design, is always less than the area of the surface that surrounds the region (measured in square Planck units). — Brian Greene

Youth is only being in a way like it might be an animal. No, it is not just like being an animal so much as being like one of these malenky toys you viddy being sold in the streets, like little chellovecks made out of tin and with a spring inside and then a winding handle on the outside and you wind it up grrr grrr grrr and off it itties, like walking, O my brothers. But it itties in a straight line and bangs straight into things bang bang and it cannot help what it is doing. Being young is like being like one of these malenky machines. — Anthony Burgess

Every human being is born without faith. Faith comes only through the process of making decisions to change before we can be sure it's the right move. — Robert H. Schuller

The entropy of the hot radiation she observes as a result of her acceleration turns out to be exactly proportional to the area of her horizon! This relationship between the area of a horizon and entropy was discovered by a Ph.D. student named Jacob Bekenstein, who was working at Princeton at about the time that Bill Unruh made his great discovery. Both were students of John Wheeler who a few years before had given the black hole its name. Bekenstein and Unruh were in a long line of remarkable students Wheeler trained, which included Richard Feynman. — Lee Smolin

They are in the middle of the sidewalk, face to face, between a tobacco shop and a trash can. Everything they've never said flows into the narrow space between them. — Alexis M. Smith

Restored in you, to be renewed in you, to receive from you — John Eldredge

What those two young physicists did remains the most important step yet made in the search for quantum gravity. They gave us two general and simple laws, which were the first physical predictions to come from the study of quantum gravity. They are: Unruh's law. Accelerating observers see themselves as embedded in a gas of hot photons at a temperature proportional to their acceleration. Bekenstein's law With every horizon that forms a boundary separating an observer from a region which is hidden from them, there is associated an entropy which measures the amount of information which is hidden behind it. This entropy is always proportional to the area of the horizon. — Lee Smolin

Like Gnostics, contemporaries feel alienated from their roots and are seeking to overcome the alienation. They are seeking new outlets for their unconscious. Where Gnostics feel cut off from the outer world, contemporaries feel cut off from the inner one. Contemporaries do not, like Gnostics, project their alienation onto the cosmos; through Jungian psychology they seek to discover their true selves within rather than outside themselves. They alone, then, have the chance fully to overcome their alienation. — C. G. Jung

Forgive me. I continue to underestimate the breadth of your ignorance. — Ransom Riggs
