Re: Scientists Create Life!

Sure, entropy allows for increased order in a part of the universe, but the sum of the universe has to decrease in order (increase in entropy). Apply that biology - and what you have is an increase in order as the norm, not as the exception.

I really hope you failed your "advanced" physics class if you are gonna offer poop like that up.  If you really did understand what the hell you were talking about, you would not say such crap.

Top of class if it matters to you - through all three semesters of lower division physics.

Well then you should be able to tell me why the second law of thermo has no applicability to earth, right?

Which is why I said "apply the concept" and not "apply the law"
The concept demonstrates itself far beyond thermodynamics - I need to see a demonstration of the concept failing before I can accept that the concept does not apply.

When we shoot radiation at emvryos to intentionally cause mutation, we see increase in entropy - and lower survival rate.

When biologists/breeders inject hormones into frogs to breed them - we see higher deformity rates, we see lower survival rates.

This is all demonstration of the concept of entropy in the field of biology - and I have never seen a demonstration of the opposite, where order increases.

Sure - we can get rid of cancer sometimes with radiation - but that's by killing the cells, an increase in entropy.

Where can you show me that the concept does not hold true in biology?

Re: Scientists Create Life!

Right...... And yet above you were complaining about scientists doing bad science.

Lets see, order increasing in biology.  Well, take a fertilized egg of a human.  Watch it grow.  That's a huge increase in order.  That tree in your front yard is converting water and co2 (both of which are very high in entropy) to a tree (which has a very low entropy level).  Both of those things violate the "concept of entropy" and are specifically why entropy has a very basic condition for application.

There's a nasty uncontrolled fusion reaction about 150 million kilometers away that's payin' our entropy price right now (and then some).

No second law of conservation of energy problems here, thank you very much. Move along.

Yeah, so.  You asked for an example of biology having a decrease in entropy, I provided two.  Unless you are using some weird definition of entropy, in which case please define it so that I can see it.  I'm using the standard one.

Re: Scientists Create Life!

Mo' ron. The intentionality of the system has no impact on the entropy calculation.  And with a tree or a person, they are more ordered over time because you can ignore the outputs of the system, as res has wanted to do.  Because he is ignoring the closed system requirement, the O2 released, which is disorderly (though even O2 is more orderly than CO2 IIRC) there is more order in the tree itself because it has grown a bit, so there's more orderly tree.

With cleaning your room, it is more ordered than before, but the heat energy you expended to clean was more disorderly than the order created.

Anyway, the point I want to make (and that you get) is that entropy statements really only make sense when using closed systems.

Re: Scientists Create Life!

The problem with the tree and the fetus is that they do what they do because they are programmed to do what they do (just like a computer program is programmed by a coder, and not random bits)

This programming is in their DNA.

They do what is in their genetic code, which is why we can predict what they will do - a fetus will grow inside it's mother and develop in a very predictable fashion, so predictable that when it doesn't - we know something is wrong.

If you wish to say evolution happens because it was programmed to, then you have intelligent design. If evolution hasn't been programmed to, then you have random chance occurrence - like my examples where mutations are caused by a radiation blast or homone injection.

While we certainly have demonstrated in lower life forms that the gene pool is able to adapt to produce a higher survival rate in a different environment, that isn't an increase in complexity. That isn't going from a mouse to a giraffe, rarely does speciation occur - and when it does, wether it actually is speciation is highly debatable.

What does any of that have to do with entropy?  Nothing?  Good, cuz it doesn't but you seemed to think that is did, which is what all that harping was about.  You claimed that the "concept of entropy" showed that life could only devolve.  I was using those to show that life is not bounded by the 2nd law.  Follow that?

There was a fatal flaw in the lightning creating amino acids experiment, the trap removed the amino acids, and the lightning would have  destroyed the amino acids on the way back, it produced right and left handed amino acids life as we know it only use left and right are toxic, and also about 98%, if memory serves me correctly, of the yield was tar which is toxic to life.  the guy who devised the experiment now admits that it is not a good example

I don't think you comprehend what I mean by apply the concept to a non thermodynamic scenario.

Let me try a basic one.
If you have 10 pennies - there are several different states they can be in.

10 heads and 0 tails
9 heads and 1 tail
8 heads and 2 tail
etc.

There is only one way to get 10 heads - it is a highly ordered state.
There are 10 ways to get 9 heads and 1 tail - it is still highly ordered.

As entropy predicts - when you penny flip experiments, and you let randomness have it's way - you most often will get 4 heads, 5 heads, or 6 heads. These are the most disordered state. A random flip is where entropy applies - there is not outside interference.

Now - I could have a machine that takes random pennies and sets them all heads up. Is that breaking entropy? No, because the machine is programmed to take a specific action - it is not a random byproduct of the machines operation. It creates 10 heads by design.

Similarly, you can program a machine that reduces the entropy of a gas in a jar - a simple heat pump will do it. This does not mean that entropy fails, only that there was design to reduce it. The gas isn't acting in random fashion.

Similarly, while a tree from the time it sproute until it is a beautiful display - it does take raw materials and use them to create an ordered structure. However - like my penny machine, like the heat pump, it does it by design - what it's genetic code has programmed it to do, it is not a random scenario.

Do you understand what I am saying?

Now - lets look at what evolution says - species going from less complex to more complex. Either it has to be by design, as the the penny machine, heat pump, and tree is - or it is a random occurence.

Which is it?
If it is random, then your tree analogy fails because the tree does what it does by design.

If it is by design, then there is a designer.

entrophy, being a basic condition, means that it always is true.  Order does not increase. we proved spontanous generation false over a hundred years ago.  There is a reason why it is the secound LAW of thermodynamics, and the theory of evolution

Re: Scientists Create Life!

Well, earlier you were trying to apply the complexity of life as a violation of increasing entropy idea. If I understood you correctly, you were stating that the evolution of species violates entropy because they are getting increasingly ordered.

But there is a mechanism at work here as well: reproduction. When mutation occurs, an unfavorable mutation (arguably the most likely mutation) will also likely leave mutatee unable to breed and pass along his genes. Favorable mutations are perpetuated more often than unfavorable ones and allows for evolution to occur.

(Of course your penny machine example violates the first principle of entropy, as does the Earth and life itself: it must be a closed system.)

Re: Scientists Create Life!

No.
You can rationalize why evolution is a case where systems become more ordered all you want - but the bottom line is that until you can demonstrate a system become more ordered without being guided to have that increase, I don't buy it.

And of course, you can't use evolution as an example of a system become more complex and more ordered, as that would be circular - since we have never witnessed the evolutionary process produce an organism that is more complex/ordered than it's parent gene pool.

With respect to who doesn't understand entropy - I'm not the one who gave examples where the effect was caused by pre-determined programming.

Ok, let me spell this out very clearly.  The calculation of entropy has no value for intentionality.  Just because it is "supposed" to do a specific thing does not matter when calculating the entropy of a system.  You are wrong.

Edit: do you want me to actually do the entropy calculations?

Re: Scientists Create Life!

It does it because it was designed to do it.
Either you are not understanding this simple point, or you are being intentionally unintelligent.

I do not have any problems with an increase in order if there is a design behind it. I have stated as much several times.

Evolution says there is an increase in order without a design for how it will happen, it happens by random chance - or so they say.

If you want to say evolution was designed to do it, then you are speaking intelligent design - otherwise, you need to find an example where in biology order increases by accident.

Remember - I said apply the concept, not the law.
The concept of the second law is applicable in almost every field of science (all that I can think of) - even if it can't be quantified to make the necessary experiments with which to call it theory and then law.

Evolution is unique in that it claims a scenario where the opposite happens, and that is troubling - especially when we see the effects of random genetic change - other than in Marvel Comic Books, they do not benefit the system - but are either benign or damaging to the system.

Re: Scientists Create Life!

It should also be noted that your tree example actually does have an increase in entropy - much of which actually occurs within the sun which provides the needed energy for the tree to take the raw materials and follow it's design.

No smurf, sherlock.  And if you make the box large enough s.t. you reach a closed system, yes, the second law is conserved.  But entropy only necessarily increases in a closed system.  But you wanted an example of entropy decreasing in a single organism.

Do you even know how to calculate the entropy of a given system?  And where in the calculation does the entropy get a positive coefficient for "intentionality"?

In a closed system (with no outside interference) "The Universe" the entropy of the universe will remain the same or increase over time.

Entropy is a measure of the disorderliness of the the universe (the closded system) and in thermodynamics is measured in terms of the change of entropy, which can be calculated by the change in random kinetic energy (temperature)

No poop, sherlock.  And if you make the box large enough s.t. you reach a closed system, yes, the second law is conserved.

But your example requires the energy of the sun for it to take place.
You therefore can not ignore it, otherwise you are taking a system and allowing an outside entity to act on the system, and claiming a net decrease in entropy.
