Life, the Universe, & the 2nd Law of Thermodynamics

  1. 1. Life, the Universe, & the 2nd Law of Thermodynamics The Infinite Probability Drive John Ashmead
  2. 2. 2nd Law of Thermodynamics The law that entropy always increases holds, I think, the supreme position among the laws of nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwells equations - then so much the worse for Maxwellsequations.…but if your theory is found to be against the second law of thermodynamics, I can give you no hope; there is nothing for it but to collapse in deepest humiliation. -- A. S. Eddington In an isolated system, a process can occur only if it increases the total entropy of the system.
  3. 3. What is entropy?
  4. 4. Second law Higher Energy Useful work Lower energy
  5. 5. Counter- intuitivecharacter ofdisorder
  6. 6. Maxwell’s Daemon “A very observant and neat- fingered being”
  7. 7. Arrow of time Nothing in the statistics of an assemblage can distinguish a direction of time when entropy fails to distinguish one. -- Eddington
  8. 8. 2 way time Let us assume that the three dimensions of space are visualized in the customary faction, and let us substitute a colour for the fourth dimension. Every physical object is liable to changes in colour as well as position. An object might, for example, be capable of going through all shades from red through violet to blue. A physical interaction between any two bodies is possible only if they are close to each other in space as well as in colour. Bodies of different colours would penetrate each other without interference
  9. 9. Infinite improbability drive If such a machine is a virtual impossibility, then it must logically be a finite improbability. So all I have to do in order to make one is to work out exactly how improbable it is, feed that figure into the finite improbability generator, ...

  17. 17. Anthropic Principle
  18. 18. The inner (closest toGalactic Habitable the center of the galaxy) limit is set by threats to Zone complex life: nearby transient sources of ionizing radiation, including supernovae and gamma ray bursters, and comet impacts. Such threats tend to increase close to the galactic center. The outer limit is imposed by galactic chemical evolution, specifically the abundance of heavier elements, such as carbon.

You are the one who spreads the cooked mash on large reed mats, Coolness overcomes. ...  You are the one who holds with both hands the great sweet wort, Brewing [it] with honey and wine
