  1. "Natural " selection no longer applies to H. sap except perhaps by resistance to some otherwise lethal diseases . Human evolution is regressive due to modern medical techology perpetuating ( to reproductive success ) in the human genome line deleterious genes
  2. It would be very sad for the hybrid & a dreadful burden to put on a living creature. Look at wolf- dog hybrids & dogs are more closely related to wolves than man is to Chimps .I am surprised though that it has not been attempted & if so we should learn from it & not react as was done re- Nazi human experiments ( refuse to learn from them )-- dreadful & inexcusable as they were .
  3. Any participating nation in the Iraq conflict should respond to any sort of kidnapping or attack by ADDING signifiacantly to its support ; perhaps by sending more troops . Encrypted is right .

    Kno3

    Carefully .KNO3 is relatively heat stable to a high degree ( unless mixed with organic material ), unlike NH4 NO3 .

    Please help

    I do not understand #1 but # 2 is center of gravity being affected

    Energy in a gram

    If mass is in grams & velocity is cm/sec , is not energy equivalent in ergs ?

    Energy in a gram

    If the one gram is accelerated to near light speed so its mass increases , does the energy equivalent also increase to an observer travelling with it ? I assume it must to an stationary observer .
  8. The GF paradox does not relate to time travel . It means that clocks run slower as ones speed increases , not go backwards .Take two twins , accelerate one to near light speed on a space ship & when he gets back he will have aged only by the earth time he has been gone but his earth -brother could be a much older man ( even dead from old age )& depending on how near the traveller got to light speed .
  9. I understood that the ancestral form of all chordates was the larval form of the Echinoderms which neotenised to a reproductive stage . The bipinnaria (or its first metamorphosis to ) brachiolaria larva ?
  10. I was going to say 100! but am not sure
  11. In the debate , I identified far more with Kerry's position rather than that of Bush . Reason ? The act of termination of a non -sentient embryo is far different from that of doing it to an individual who might have anticipatory foreknowledge of his or hers pending termination ; perhaps by a deblitating disease . How is an embyo affected by its termination ? Don't say "it has been deprived of a right to life " because to be so deprived it would have to have continuing post mortem concious awareness of its situation .
  12. I do not know what to do . I cannot vote for either Kerry or Bush . Just look at Kerry's voting record ( it is on the web ) & Bush is an rigid ideologue . To vote for Nader would be a vote for Bush ; maybe I will just write in John McCain -----
  13. On all diagrams I have seen the highest frequency ( or shortest wave length ) seem to be in gamma rays. Are any frequencies higher than gamma or cosmic rays known or is there a theoretical limit ? Intuition would indicate a limit to wave LENGTH as energy content decreases as wave length increases , becoming zero at infinite wave length .
  14. OK Ophiolite , you are right re - recoverable hydrocarbons . The question goes to the ultimate consequences of fossil fuel conbustion ( a lot goes into plastics ) & some estimate of just how disasterous this might or might not be . Of course an even bigger question is what will happen when it is all exhausted especially since a large proportion of fossil fuel calories go into food production ( 40-60 % ? ) ( cultivation , fertilizer , etc ) .
  15. PS But forget about natural gas as this may not be of biologic origin .
  16. Quite true about how much is left but there are estimates .
  17. Natural magnets exert a force which is capable of doing work . It takes energy to to do work . In magnets what is the source of this energy when it is not electromagnetically induced ? I know the theories of magnetism but nowhere can I find what the energy source is --- is it nuclear ( ie by conversion of mass ) at some level ?
  18. Has any authority made a calculation re the levels of atmospheric CO2 which would come about if ALL carboniferous fossil fuel ( coal , oil etc ) left in the world was combusted ? Also any predicted effect on climate . All such fuel is a product of photosynthesis millenia ago & that required CO2 which means CO2 must have been much higher then & perhaps climate much hotter . I know it was but how much hotter ------

  22. There is no such thing as totally empty space ---don't forget virtual particles .
  23. Gravity travels at light speed as per Einstein who revolutionized Newtons concept that it was instantaneous .
  24. Uncertainty applies to many things . Consider all the equations which deal with macroscopic uncertainties . Bayes Theorem , Binomial Equation & Poisson Distribution----
  25. Creationism is another example of subjective ideology tring to prevail over rational objectivity -- in this case , twisting & distorting the facts to conform to fundamentalist religious precepts ( a la the attack on Galileo ) .
