I have given him the math, but he is completely blind to any reason. His philosophy goes something like, If it disagrees with the bible it cannot be true no matter the evidence.

Then he must also believe that slavery is a God-given right, since the Bible gives instruction on how slaves are to be treated, and allows men to sell their daughters as 'servants'.

Fundies ... :roll:

So anyone who relies on creationist sources for their information about evolution forms their opinion based on LIES they were told. And to tie in with the conspiracy nuts, somehow there is a huge conspiracy of atheist scientists who the creationists claim are making all this stuff up to deny God and mislead the public. IF there is a conspiracy about evolution, it is GOD who is the mastermind, because all the evidence of the physical world clearly shows evolution happens.

They do? Do you actually have anything - anything at all - to back up these accusations? It's easy enough to whine about 'creationists' (whoever they are), and how they are apparently destroying science, but I want clear evidence of this, and not just someone's (no doubt, biased) opinion.

You're basing all this "entropy" stuff upon the premise that there was a "nothingness."

I don't believe absolute "nothingness" is even possible.

Something always has arisen from an infinite "something."

That's fair enough.

My case all along in this, and other similar threads, is that science shows Darwinism scientifically impossible. It's the nonsciencetists who try to hide their lack of science by bringing up the Biblical account of Creation to be an object of ridicule. Which, of course, has nothing at all to do with "proving" the veracity of the list of unjustifiable gratuitous assertions that "make their case".

Entropy and enthalpy are intrinsically linked.

The universe tends towards entropy, but reactions in which entropy decreases are still energetically viable if the drop in enthalpy makes up for that. See here.

Life is an exercise in making reactions more efficient so that enthalpy changes allow entropy to decrease.

For example, proteins are more stable than amino acids or primitive polypeptides. Assembling proteins from RNA code is more efficient than just hoping they assemble without a plan. Then DNA is better than RNA, because you've got an extra strand for redundancy and it's less reactive (hence "deoxy").

Thank you. I stand by every word.

Irrational delusions may come, and irrational delusions may go, but Science marches on!

Hmm. An almost clever slight-of-mind to trick the unwary.

That energy (and thus potential) can be transferred from one system to another (as in blowing up a motor car tyre) does not imply, or cause, an overall decrease in entropy, nor does a localised increase in energy potential imply, or cause, a spontaneous creation of order.

Also, that real scientists and engineers intelligently come up with ways to minimise losses in energy transfers does not imply that entropy can be made non-existent or reversed.

Real science is not trickery. Nonscience is all trickery.

David given your understanding of entropy and the second law. Can you explain why the earth is not in thermal equilibrium with cosmic space? Indeed can you explain why the whole universe is not in thermal equilibrium?

The Sun is still shining.

Good. So you accpet that we get energy from the sun and therefore this planet is not a closed system, you also accpet that heat energy is not uniform throughout the universe.
The next question is what happens to all that solar energy. For example do you accept the principle of the conservation of energy?

The Laws of Thermodynamics require all of the above for anything physical to work.

The bulk of it is eventually dissipated into space just like the other 99.999999999999....% of the Sun's output.

I assume that this just a pretentious exercise trying to trap me into defending a straw man of your own making.

OK so we are getting somewhere. You agree that we do not live in a closed system, you agree that the universe has non uniform areas of heat energy, you agree that energy is conserved. I presume you will agree that the solar energy that is sent back into space is in the form of infra red radiation? Yes? One more thing I would like to check, do you accept that e=mc2 is a valid and rigorously tested formula?

Well, some is infrared. There must be an awful lot of the rest of the spectrum sent back out or you'd never be able to see "the blue planet" from "out there".

It seems to work in some situations. But you tell me what you get if you make one of the variables =0. And how fast relative to what must a proton be travelling to have the mass of a proton?

No, but it allows for it.

Wow! You really don't understand the mass-energy equivalency equation! Do you understand simple maths at all?

You can't make 'c' zero, because that is an established constant; and making 'E' equal zero makes 'm' equal zero, and vice-versa.

Did you flunk algebra, or do you actually believe that your pseudo-scientific ideas have any validity in the real universe?
