What do you mean about how you value yourself?
I don't care how smart you are in this world, we are all the same worth.
I like your religion.
Thank you, Brother!

There are a few on this board who will dive straight into quantum mechanics as soon as the idea of a cool object further warming a warm object is called into question.....and they speak of quantum mechanics as if it, like climate science is "settled" science.
A recent survey was done and it seems that insofar as quantum mechanics goes, there is little that the "experts" agree on. This belief that any science is settled and not subject to question seems to be one of the more serious symptoms of postmodern science.
This poll was given to the participants of a quantum foundations confrence. Here are some of the results...
Randomness of quantum processes (e.g. decay of nuclei) is:
64%: fundamental
48%: irreducible
9%: only apparent
0%: masking a hidden determinism
Do objects have well-defined properties before measurements?
52%: yes, in some cases
48%: no
9%: undecided
3%: always
Einstein's view on quantum mechanics is:
64%: wrong
12%: will be shown wrong
12%: we don't know
6%: will be shown right
0%: is right
Bohr's view on quantum mechanics is:
30%: we have to wait
27%: wrong
21%: correct
9%: will be shown right
3%: will be shown wrong
A similar split appears when it comes to the measurement problem:
39%: solved (now or later) in a different way
27%: a pseudoproblem
27%: none of the above
24%: a severe difficulty threatening QM
15%: solved by decoherence
What is the message of the violation of Bell's inequalities?
64%: local realism is untenable
52%: unperformed experiments have no results
36%: some notion of nonlocality
12%: action at a distance in the physical world
6%: let's not jump the gun, take loopholes seriously
Quantum information is:
76%: fresh air in quantum foundations
27%: we need to wait
6%: useful for applications but of no relevance to foundations
6%: neither useful nor relevant
When will we have a working and useful quantum computer?
9%: within 10 years
42%: 10-25 years
30%: 25-50 years
0%: 50-100 years
15%: never
Right interpretation of state vectors:
27%: epistemic/informational
24%: ontic
33%: a mix of epistemic and ontic
3%: purely statistical as in ensemble interpretation
12%: other
The observer is:
39%: a complex quantum system
21%: should play no fundamental role whatsoever
55%: plays a fundamental role in the application of the formalism but plays no distinguished physical role
6%: plays a distinct physical role (soul collapses wave function...)
Reconstruction of quantum theory:
15%: gives useful insights and has/will supersede the interpretation program
45%: gives useful insights but we still need an interpretation
30%: cannot solve the quantum foundations
27%: will lead to a deeper theory than QM
12%: don't know
Favorite interpretation:
0%: consistent histories
42%: Copenhagen
0%: de Broglie-Bohm pilot wave
18%: Everett many worlds/minds
24%: information-based
0%: modal
9%: objective collapse, GRW or Penrose
6%: quantum Bayesianism
6%: relational quantum mechanics
0%: ensemble interpretation
0%: transactional interpretation
12%: other
12%: no preferred one
How often have you switched interpretation?
33%: never
21%: once
21%: several times
21%: no preferred interpretation
Does the choice of interpretation depend on philosophical prejudices?
58%: a lot
27%: a little
15%: not at all
Superpositions of macro- different states are:
67%: possible in principle
36%: will eventually be realized
12%: in principle impossible
6%: impossible because of collapse theory
In 50 years, conferences on quantum foundations:
48%: will still be organized
15%: probably no
24%: who knows
12%: I organize one no matter what
So the next time you (and you know who you are) feel like making statements regarding QM as if it were settled science, remember that even the "experts" are in disagreement on damned near everything.
SSDD- your biggest hurdle in getting a handle on thermodynamics is understanding that it is a description of energy flow in a system built up of large numbers of things. the arrow of time is a murky process that only becomes clear as you move to larger systems with more degrees of freedom.
I am not a physicist, my concept of fields and photons is rudimentary at best. if you prefer the eccentric view of Johnson, or someone else, then that is your own business. if their views match reality as closely as the more standard explanations then they are at least possibly on to something. good luck to them, and I hope you experience the thrill of backing a longshot to victory.

I believe your biggest hurdle in getting a handle on theromdynamics is your belief that anyone who disagrees with you has failed to get a handle on thermodynamics and your second biggest problem is your willingness to disregard the laws of thermodynamics in favor of untestable, unproven, mathematical models....and then state those models as if they were fact rather than hypothesis still awaiting any real world experiment to test them.

Look at the history of science...the percentages suggest that backing the longshot who can actually do the math to prove his position is a far better bet than backing the status quo who does little more than call him a heritic and point to their own untestable, unproven dogma as proof that he is wrong.
hahahaha, as you wish. there have been thousands upon thousands of physicists who were sure they were right, only they weren't. no one remembers their names.

And yet pseudo experts claim everyday on this message board that they and only they know truth and that science itself is less a reliable source of knowledge than intuition, faith or the proof provided by charlatans who profess to be all knowing. Let's take climate change for an example:
Self proclaimed conservatives claim, either:
1. There is no climate change, only anomalies, or
2. Climate change is episodic, has nothing to do with human activity, or
3. It snowed, proving there is no global warming.
And all parrot some arcane statistic as proof of some absolute truth; the non parrots make no such absolute claim. For the most part the non parrots recognize that SMOG and ACID Rain were a product of human activity and that each was mitigated by the application of scientific inquiry and government action; understand that something is happening but as of yet cannot pinpoint the causes but believe there may be many reasons for the effects (climate extremes).
It is not the non parrots who hold as absolute that human activity has no major, world-wide impact on our environment; it is the deniers who do, and in that I'm 99.9% sure.
Considering the fact that neither you, nor any other warmist, including all climate scientist can present a single bit of hard evidence proving that mankind is altering the global climate, it is you and yours who profess to be all knowing in spite of evidence to the contrary. I can be convinced, but it will require proof. I don't base such things as positions on scientific issues on my political leanings. Show me some hard proof that we are causing the global climate to change, or show me some hard proof that the climate today is unprecedented in the history of the earth and then you have an argument. Till you can do that, all you have is an untestable, unfalsifiable hypothesis.
[/quote]And what if the 'warmers' are correct and you are wrong? That's the point, doing nothing can be cataclysmic, doing some things (being green) has a number of benefits besides the potential to protect the earth.
Disappearing in one place and reappearing in another. Being in two places at once. Communicating information seemingly faster than the speed of light. This kind of weird behaviour is commonplace in dark, still laboratories studying the branch of physics called quantum mechanics, but what might it have to do with fresh flowers, migrating birds, and the smell of rotten eggs?
Welcome to the frontier of what is called quantum biology. It is still a tentative, even speculative discipline, but what scientists are learning from it might just spark revolutions in the development of new drugs, computers and perfumes - or even help in the fight against cancer. Until recently, the delicate states of matter predicted by quantum mechanics have only been accessed with the most careful experiments: isolated particles at blisteringly low temperatures or pressures approaching that of deep space.
Deep within plants' energy-harvesting machinery lie distinctly quantum tricks
The idea that biology - impossibly warm, wet and messy to your average physicist - should play host to these states was almost heretical. But a few strands of evidence were bringing the idea into the mainstream, said Luca Turin of the Fleming Institute in Greece. "There are definitely three areas that have turned out to be manifestly quantum," Dr Turin told the BBC. "These three things... have dispelled the idea that quantum mechanics had nothing to say about biology."
The most established of the three is photosynthesis - the staggeringly efficient process by which plants and some bacteria build the molecules they need, using energy from sunlight. It seems to use what is called "superposition" - being seemingly in more than one place at one time. Watch the process closely enough and it appears there are little packets of energy simultaneously "trying" all of the possible paths to get where they need to go, and then settling on the most efficient. "Biology seems to have been able to use these subtle effects in a warm, wet environment and still maintain the [superposition]. How it does that we don't understand," Richard Cogdell of the University of Glasgow told the BBC.
