Hyperlinks as Conversation
Hyperlinks are fine-grained, bidirectional, and extrinsic. Frequently, an argument is not with a document or chapter as a whole. It is with a particular point that someone made at a particular place in the text. For example, someone refers to the fourth law of thermodynamics, and someone else writes a criticism saying there is no fourth law of thermodynamics, linking it to the original. The fine-grained property allows the link to designate the particular piece of text with which one is takin... 1

Hawking's Equation
awking has written down an equation which looks rather like Planck's equation. Hawking's equation is S = kA, where S is the entropy of a black hole, A is the area of its surface, and k is a constant which I call Hawking's constant. Entropy means roughly the same thing as the heat capacity of an object. It is measured in units of calories per degree. A is measured in square centimeters. Hawking's equation says that entropy is really the same thing as area. The exchange rate between area and en... 1 notes

Ontological paradox
Because of the possibility of influencing the past while time traveling, one way of explaining why history does not change is by saying that whatever has happened was meant to happen. A time traveler attempting to alter the past in this model, intentionally or not, would only be fulfilling his role in creating history, not changing it. The Novikov self-consistency principle proposes that contradictory causal loops cannot form, but that consistent ones can. This theory, however, only makes sen... 1 notes
notesA paradox of time-travel. If a person takes information back in time and gives it to someone, who becomes the originator of that information, then where did the information originate?

Life is "Enclaves" in a Whirlpool of Chaos
THE FOLLOWING IS QUOTED FROM BERGAN EVANS
ON NORBERT WEINER, NUCLEAR PHYSICIST
The second concept Wiener has to establish is that of entropy. Probability is a mathematical concept, coming from statistics. Entropy comes from physics. It is the assertion-- established logically and experimentally-- that the universe, by its nature, is "running down", moving toward a state of inert uniformity devoid of form, matter, hierarchy or differentiation.
That is, in any given situation, less organizat...

You want a physicist to speak at your funeral
You want a physicist to speak at your funeral. You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the first law of thermodynamics; that no energy gets created in the universe, and none is destroyed. You want your mother to know that all your energy, every vibration, every Btu of heat, every wave of every particle that was her beloved child rem...Folksonomies: science spirituality

Why is Scientific Illiteracy Considered Acceptable?
A good many times I have been present at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and have asked the company how many of them could describe the Second Law of Thermodynamics. The response was cold: it was also negative. Yet I was asking something which is about the scientific equivalent of: Have you...When failing to read Shakespeare is considered unacceptable?

Evolution and Entropy are Irreversible
Evolution in the biosphere is therefore a necessarily irreversible process defining a direction in time; a direction which is the same as that enjoined by the law of increasing entropy, that is to say, the second law of thermodynamics. This is far more than a mere comparison: the second law is founded upon considerations identical to those which establish the irreversibility of evolution. Indeed, it is legitimate to view the irreversibility of evolution as an expression of the second law in t... 1 notes

Similarities of Natural Selection to the Laws of Thermody...
It will be noticed that the fundamental theorem proved above bears some remarkable resemblances to the second law of thermodynamics. Both are properties of populations, or aggregates, true irrespective of the nature of the units which compose them; both are statistical laws; each requires the constant increase of a measurable quantity, in the one case the entropy of a physical system and in the other the fitness, measured by m, of a biological population. As in the physical world we can conce... 1 notes
