Black Hole: How an Idea Abandoned by Newtonians, Hated by Einstein, and Gambled on by Hawking Became Loved

For greater than part a century, physicists and astronomers engaged in heated dispute over the potential for black holes within the universe. The weirdly alien suggestion of a space-time abyss from which not anything escapes—not even light—seemed to confound all good judgment. This engrossing publication tells the tale of the fierce black gap debates and the contributions of Einstein and Hawking and different major thinkers who thoroughly altered our view of the universe.

Not Even Wrong: The Failure of String Theory and the Search for Unity in Physical Law

At what aspect does idea leave the world of testable speculation and are available to resemble anything like aesthetic hypothesis, or perhaps theology? The mythical physicist Wolfgang Pauli had a word for such principles: He could describe them as "not even wrong," that means that they have been so incomplete that they can now not also be used to make predictions to check with observations to determine whether or not they have been flawed or now not.

Example text

Fluorescent lamps produce light in a different way, by energizing gas. Electrical energy flows into electrodes at the ends of a tube. The electrodes emit electrons, which energize a small amount of mercury vapor held at very low temperatures inside the tube. The energized mercury molecules radiate ultraviolet light, which is in turn absorbed by a phosphorescent coating on the inside of the surface of the tube, thus producing visible light. This process produces very little heat; fluorescent lamps are able to convert almost 90 percent of the energy they consume into light.

But scientific laws need not be universal; some laws claim only that a particular kind of behavior will occur in a certain proportion of cases. Suppose we were to learn that a good friend, a nurse, has contracted hepatitis B. We are aware that he works in a clinical setting where patients with hepatitis B are regularly rreated. ' It seems a real possibility that our friend's condition is explained, in part, by the statistic we have just cited. The explanation we might give would go something like the following: Exposed health care workers have a 25 percent chance of contracting hepatitis B.
