[QUOTE=jwaltos;464016]Sardonicus, rather than skim the opposite is required. There are some within this forum that have read (and understood) a vast amount of literature on a wide variety of topics. Synthesis of outliers, re-framing contextual perspectives and connecting seemingly disparate concepts in a unique and meaningful way requires experience and exposure. Professional longevity within evolving fields requires agile minds whose valued opinions I`m trying to elicit. My question involves sentience which parallels Penrose`s view and its origin from an initial state from some confluence of ``forces and fields`` to its present possible expression as a microtubule whose function may be modelled mathematically and virtually (slight pun).

As an addendum please read David Bohm`s works which are equally instructive.[/QUOTE]

I wish I had the time. Meanwhile, back at the Forum, I mentioned a very basic fact about human consciousness:

When we sleep, our consciousness [i]goes away[/i]. And when we wake up, it comes back.

And I ask: Does "quantum coherence" address this fact?

If it doesn't address it, fine. If it does, so much the better. But if you want to say. "You haven't read the literature, so you're not entitled to an answer," the rules of the forum would not allow me to post a fitting reply.

Hi,
On a Science/Discovery channel recently there was an experiment on a person shown where when one is awake neuron firing will propagate through the brain whereas when one is asleep the same stimulus will remain localized. I do not know how quantum coherence/de-coherence is involved in such a process. The above study is being expanded and I am certain there are research papers available.


My communication skills aren't the best so I apologize for seeming officious. My intent was and is to state that there is no substitute for clear thinking regardless of how obtained.

I'm guessing it's a particular kind of neuron firing. After all, we have dreams, which involve activity in various parts of the brain. A curious thing about dreams: I have many times had rather vivid dreams, and can remember that I had them, but am unable to recall anything of what they were about. Sometimes I can feel the recollection of the dream slipping away as I wake up. I know that this is quite common.

Alas, clear thinking, rationality, and the basic importance of facts, seem to have gone out of fashion here in the good ol' USA. The founders of this nation were very much Enlightenment figures, and saw science and rational thought as a way to improve peoples' lives. Now, it appears that the Enlightenment has ben repealed and replaced by a nation of brainwashed zombies.

In his 1838 [url=http://www.abrahamlincolnonline.org/lincoln/speeches/lyceum.htm]Lyceum Address[/url], Abraham Lincoln said [quote]Passion has helped us; but can do so no more. It will in future be our enemy. Reason, cold, calculating, unimpassioned reason, must furnish all the materials for our future support and defence.[/quote]

From that standpoint, I'd say our nation is in a [i]heap[/i] o' trouble.

Snip, with some required added qualifiers in [], based on the now-established non-standardness of said 'candles':
[quote]The findings, which have been posted on the arXiv preprint server and accepted for publication in the Astrophysical Journal, could help astronomers to calibrate measurements of the Universe’s expansion. Tracking type Ia supernovae [appeared to show] that the Universe is expanding at an ever-increasing rate, and [allegedly] helped to prove the existence of dark energy — [purported] advances that secured the 2011 Nobel Prize in Physics.

The fact that scientists don’t fully understand these cosmological tools is embarrassing, says the latest study’s lead author, Griffin Hosseinzadeh, an astronomer at the University of California, Santa Barbara. “One of the greatest [supposed] discoveries of the century is based on these things and we don’t even know what they are, really.”[/quote]

makes sense ... the two parts that I know of where the nervous system and endocrine both cross are the hypothalamus and the adrenals ( both parts of the HPAA ( hypothalmic- pituitary-adrenal axis), which also regulate the endocrine system a lot at last check).

It's always bothered me that folks sounded so [i]certain[/i] about the "standardness" of type 1a supernovae. The basic explanation seemed to go, "When they accumulate x amount of mass from a companion, BOOM!"

Or maybe, "accumulate enough mass to reach critical mass x." Apparently, the white dwarf just has to be compressed enough to get carbon and oxygen to start fusing into iron.

I had thought of possible variations -- in the white dwarf's starting size, or in its composition -- that might affect when the fireworks go off, and how big the bang might be. But I hadn't thought of a collision with its companion!

maybe some of the thought "standardness" was from a newtonian viewpoint? under relativity are there any times when two things can look the same brightness etc. but not actually be ? if so maybe that's a cause ?

Light loses energy (as seen from infinity) as it leaves a massive body. It becomes fainter. Two bodies of equal brightness as measured at their surfaces will have different brightness as measured from infinity. However, their light also becomes redder (this effect is also better known as the gravitational red-shift) and an observer at infinity can distinguish between the two on the basis of their spectrum. I'm guessing that this effect is included in your "etc."
