but does our body release comparative amounts of heat when we are not under stress? i don't think so. for instance, a peaceful thought could be relatively free of any type of heat. also, some have been known to deal quite well with stress and lie on lie detectors. they don't even use heat for lie detectors. they use something else. electrical/neural impulse.
The body naturally releases heat as a result of functioning. When under stress, heart rate increases supplying more blood to the brain allowing it to function faster and perform better usings more electricity. I don't know that the body releases MORE heat because of this, and it would also likely be difficult to measure. My point is, however, that in order to exist properly we release heat to satisfy entropy.
In terms of lie detectors, I believe many work by monitering heart rate, but I'm not expert.
cat scans use the heat to find active areas of the brain - but who is to say that is the final answer? what if some areas of the brain (or ALL of the brain) actively functions in some way or other. neural paths can be very long and circuiotous as one gets older, right. you have these paths that are developed.
Being that the brain is made up of a fairly uniform composition and that it is well known that the brain is made up of a neural network I believe it is unlikely that parts of the brain function differently. Although areas provide separate functions they all work in the same way. The difficutly is in mapping and following the sheer number connections the neurons make. It is being considered to embark on another Human Genome scale project in order to fully and properly map the brain. Such a project would surely provide great insight.
An interesting note about these neural networks is that scientists studying robotics have been able to create artificial intelligence that uses primitive neural networks to "learn." Even more interesting is that these robots need a chance to "dream" in order to make sense of the many connections the network makes much like humans. Very interesting reading on the subject can be found in Michio Kaku's
Visions
all of our senses are minutely developed and were that way since creation. you can't find a mummy without eyeballs or fingers (unless they were gouged out or cut off). and, we know from archeology that humans were quite adept at things wayyy back when - otherwise - how did the pyramids get built?
I believe its likely that over time we've become less aware of our senses. We no longer need as sharp a sense of sight, smell, or sound to survive, so it is quite possible they have diminished over the years. Though, it is difficult to say.
as i see it - conservation is PRECISION. you have absolute numbers that don't change. the laws of physics are precise. when you look at an elements chart - you see real precision. it was decided and constant throughout. we know this because helium is everywhere in the universe. there is no place that helium has not been found. and it is found in EQUAL amounts. that is startling to anyone who wants to prove evolution true.
I don't quite see how this counters an argument for evolution. Helium is found everywhere in the universe because of the nature of its construction. Elements heavier than hydrogen are produced once a star finishes burning its initial hydrogen fuel source. This continues down to iron. Elements heavier than that are produced during supernovae.
Also, its not truely found everwhere. The majority of matter in the universe is clumped around galaxy clusters, which are separated by vast voids. It's difficult to say that its found in equal amounts everywhere as well. However, the ratio of Helium compared to other atoms is about equal anywhere in the universe, again, because of its construction. The amount of helium produced is relative to the size of the star/number of stars in a given area.
Also, a funny note. Helium was named after Helios from the Greek word for the sun, as scientists who discovered it believed it is what the sun was made of. Ironically, after the discovery of spectral analysis, it was determined the sun was comprised of hydrogen (though eventually once the sun runs out of hydrogen it will start burning helium)
*to stay on topic - i must - hmmm law of conservation, alchemy, perfection. sounds like someone is looking for a formula. but, what if there is a much simpler formula for perfection that anyone thinks? what if it is a thought that is not our own. what if it is found in the life giving Holy Spirit. the one that adam and eve rejected when they ate the fruit of the tree of good and evil (deciding for themselves what good and evil were) - instead of the tree of life. eternal life. that is perfection. living forever in the light of God. the other way is complete darkness.
String theory strives to provide a 'perfect' formula that explains the universe perfectly (uniting Einstein's Relativity and the Standard Model of Quantum Theory) Though, practical tests to test the theory are years away due to copious amounts of energy required to test them. On the subject on this and the rest of the universe, I recommend two more of Michio Kaku's books
Hyperspace and
Parallel Worlds
ps some scientists say (with complete confidence?) that other galaxies have largest number of elements that are made of heavier materials than hydrogen and helium. i would like it proven. when God created everything - i believe He was simple in His plan. Therefore - I think it is entirely possible to create something similar to our galaxy with exactly the same materials but a different floor plan.
Again, I'd recommend the two above books for discussion on this subject. The reason some galaxies have greater amounts of larger elements is simply due to the number of supernovae that have occured to produce them. It is also rather difficult to create a galaxy no matter what you have to build it with
