LHC Detects Evidence of New Physics | Wired Science | Wired.com
"After nearly 6 months of smashing particles, the Large Hadron Collider has seen signs of something entirely new. Pairs of charged particles produced when two beams of protons collide seem to be associated with each other even after they fly apart. “It is a small effect, but it is very interesting in itself,” said physicist Guido Tonelli, spokesperson for the LHC’s CMS experiment. Tonelli and colleagues announced the results in a seminar at CERN September 21 and in a paper submitted to the Journal of High Energy Physics." - Spaceweaver from Bookmarklet

Draft of article on free will online - http://bjoern.brembs.net/news...
I've made my comments in red. Some are more about taste than accuracy though. Toward the end of the text you make statements that suggest (at least to me) that an animal's actions remain unpredictable even with COMPLETE knowledge its genes and environment. I have a slight problem with this, because we don’t yet know whether the nonlinear amplification process (and whatever seed it uses)... more... - Christopher Harris

This is weird, others are commenting. Thanks for your edits, they are very helpful (and reminded me of some other Aplysia work that I desperately need to cite but forgot!). Thanks so much! Do you have the exact error message? - Björn Brembs
Wow - this is great that the journal's copyright policy allows this type of pre-print "Royal Society Publishing allow authors to retain copyright. Instead, authors need to provide us with a licence to publish." - Jean-Claude Bradley
Glad you checked this - I just posted it, hoping it would be ok :-) - Björn Brembs
i get the same error : acess denied . when trying to post a commnet. hence posting it here: - Sandeep Gautam
1. are you familiar with donald T campbell's blind variation and selective retention theory of creative thought. It is very similar to the two phase theory of 'creative/unpredictable' behavior that relies on a spontaneous variation first step followed by determination of app. criterion fit (selection); in my view you need to elaborate on the two phase evolutionary theory of free will... more... - Sandeep Gautam
This 'access denied' is new. Don't know what's going on, I suspect a recent security update I installed. - Björn Brembs
@Sandeep: because the focus of the article is on invertebrate data, I'll have to refrain from going too deep into the philosophical aspects, but I'll look the things up that you mentioned and will see how much I can incorporate. - Björn Brembs
Ok, I know what the problem with 'access denied' is. Am working on solving it. - Björn Brembs
Bjorn - if I understand your point this is basically the application of chaos theory to neurobiology? If so maybe add an appropriate ref - Jean-Claude Bradley
That's part of it, yes. I've been thinking to add a reference, but the mathematics guy behind our analysis (George Sugihara) didn't really like the terminology and preferred 'nonlinearity', so I guess he must have a reason (we didn't have enough time to discuss (i.e., him explaining it to me :-) this thoroughly. - Björn Brembs
Well, there are various mathematical definitions of "chaos" and personally I would be wary of using the term unless I had a particular dynamical system and a particular definition in mind. However, replacing it with the word "nonlinear" is, to my mind, even worse because there are many nonlinear dynamical systems that behave in a perfectly predictable way. It all depends on the precise... more... - Matt Leifer
I'll comment on the "Rejection of Determinism" section, since quantum mechanics is my area. Firstly, I don't see what the uncertainty principle has to do with Hawking radiation. It is not used in the derivation as far as I am aware, although some (sloppy) physicists might use it as a heuristic justification. It also seems pretty far away from anything of relevance to the paper. Is it,... more... - Matt Leifer
I forgot to say that I do like the main argument of the paper. It seems to be as close to an account of "free will" as it is possible to get within a materialist worldview and is similar in spirit to Daniel Dennett's treatment of consciousness. - Matt Leifer
Those are great comments, Matt, and most of them will make it into the paper, I'm sure. Thanks in particular for the Buckyball paper, I was looking for it but couldn't remember enough of it to find it! WRT Hawking radiation, in his book (or where did I read that?) I remember him telling us that near black hole s(at the event horizon?), some parameters (field strengths? english?) would... more... - Björn Brembs
It will be interesting to see what the reviewers say with respect to terminology - I think the specific concept is the butterfly effect - part of chaos theory but not necessarily involving attractors and other components of CT http://en.wikipedia.org/wiki... - Jean-Claude Bradley
I'm not sure what to make of that explanation for Hawking radiation, but then it is difficult to give an accurate explanation for it at the popular level. Physicists often use the uncertainty principle as a heuristic guide for what the quantum physics of a given scenario will look like, often using it in a way that is not strictly valid. The rigorous version of the argument usually does... more... - Matt Leifer
@JC: yes, "sensitive dependence on initial conditions" would be the butterfly effect. There is too little known about the mechanisms, however, to be all that specific. The article, to some extent, tries to draw attention to what we don't know, yet. I probably should be emphasizing this more. It sort of gets lost in my attempt to get people to acknowledge that this is a valid neurobiological research field at all. - Björn Brembs
@Matt: I had to derive the uncertainty principle for my high-school graduation exam and Heisenberg's youngest son was my thesis advisor. That's my background from which I'm working. - Björn Brembs
I'll use the remaining week to get all these wonderful comments in and I hope there will be more! The paper is already much improved from what has come in so far! Thank you so much, keep it coming! - Björn Brembs
I think the "Rejection of determinism" section has to be done away with and re-written. The examples, I agree with Matt, are not really pertinent. For example, Hawking radiation, it is a semi-classical result, and some physicist don't think it is even real, though they are in the minority. I wouldn't mention it at all. I think you can say that most physicists agree that QM destroyed... more... - Andrew Lang
Commenting issue fixed! - Björn Brembs
@Matt: what about this paper, WRT fullerene double-slit results: http://www.springerlink.com/content... ??? - Björn Brembs
OK, the discussion has veered too much in QM direction (to my discomfort as I'm not much at ease there) and I thought the focus should have been more neurobiological:-) I see that you dont reference Libet or the more recent experiments showing how conscious sense of volition may indeed be an illusion or at least follows non-conscious volition; I believe where you talk about difference... more... - Sandeep Gautam
Good point, Sandeep, that section would indeed be well suited for a Libet reference! Thank you! - Björn Brembs
RE: the fullerene paper - I was not aware of it and don't have time to look into their claims in any detail. It is always possible that there is an alternative model that predicts the same results. One would have to look carefully to check whether their proposed model contradicts anything else we know about the quantum mechanics of fullerenes. In any case, experiments are being planned... more... - Matt Leifer
The abstract for the fullerene experiment "re-analysis" is dripping with what I would normally regard as kook signifiers. I don't recognize the author names, so it's possible there's some reason to treat them seriously, but I would be highly skeptical of anything with an abstract like that. - Chad Orzel
@Matt: I heard about the planned experiments just yesterday (in a podcast). I know I don't 'need' the argument and would do away with the section of I run out of space. If I have the space, I'd like to state that 'Laplaceian' determinism is just as dead as dualism. - Björn Brembs
@Chad: thanks for the tip! - Björn Brembs

I know. It's silly. It was used before and after, by people who never heard of scienitificblogging, who developed it, defined it, and ran with it. I have no idea what fool issued that kind of copyright for a word that is in general use. - Bora Zivkovic
He seems to think that he only needs to put out cease and decist letters for commercial interests. If he only fights for his trademark in /some/ cases, then he can lose his supposed trademark. - Just Joe from iPod

IANAL but not so weird - Web 2.0 is trademarked by O'Reilly, for example. The trademark is over the whole phrase in certain contexts. Ditto this one. Still seems stupid that USPTO granted it without doing a simple check for common usage first though... - Euan
@Euan, "stupid" is the USPTO's operating mission as far as I can tell. They consistenly allow both trademarks and patents that are blatantly unsustainable and will drop at the first challenge by way of prior art/common usage. - Bill Hooker
Web 2.0 is trademarked by CMP Media, not O'Reilly. But because it was not protected it is, as Tim Berners-Lee called it, a "piece of jargon" used and misused. Hopefully Science 2.0 won't go the same route. Scienceblogs, PLoS and FriendFeed are also registered trademarks. - Science 2.0

Scientists Create First Self-Replicating Synthetic Life
"Man-made DNA has booted up a cell for the first time. In a feat that is the culmination of two and a half years of tests and adjustments, researchers at the J. Craig Venter Institute inserted artificial genetic material — chemically printed, synthesized and assembled — into cells that were then able to grow naturally. “We all had a very good feeling that it was going to work this time,” said Venter Institute synthetic biologist Daniel Gibson, co-author of the study published May 20 in Science. “But we were cautiously optimistic because we had so many letdowns following the previous experiments.” On a Friday in March, scientists inserted over 1 million base pairs of synthetic DNA into Mycoplasma capricolum cells before leaving for the weekend. When they returned on Monday, their cells had bloomed into colonies." - Spaceweaver from Bookmarklet

One Step Closer to Suspended Animation for Wounded Soldiers in 18 Months? - http://singularityhub.com/2009...
"It’s known as the golden hour. After a bullet wound or other massive trauma, soldiers in the field have about one hour to get intense medical attention. After that time, the chances of survival drop drastically. The research arm of US armed forces, DARPA, has long been interested in extending that golden window of opportunity to five or six hours, enough time to medevac someone from a remote location to a hospital. Earlier in December, DARPA announced that the Texas A&M Institute for Preclinical Studies (TIPS) would be receiving $9.9 million in funding to determine if previously successful suspended animation programs for rodents could work with pigs. According to Wired, the 15 person team lead by Dr. Matthew Miller hopes to have positive results in just 18 months. That sort of quick paced research could soon pave the way to preserve trauma victims the world over as they make their way to help." - Alexander Kruel from Bookmarklet

'We have broken speed of light' - Telegraph - http://www.telegraph.co.uk/science...
"A pair of German physicists claim to have broken the speed of light - an achievement that would undermine our entire understanding of space and time. According to Einstein's special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second. However, Dr Gunter Nimtz and Dr Alfons Stahlhofen, of the University of Koblenz, say they may have breached a key tenet of that theory. The pair say they have conducted an experiment in which microwave photons - energetic packets of light - travelled "instantaneously" between a pair of prisms that had been moved up to 3ft apart. Being able to travel faster than the speed of light would lead to a wide variety of bizarre consequences. For instance, an astronaut moving faster than it would theoretically arrive at a destination before leaving. The scientists were investigating a phenomenon called quantum tunnelling, which allows sub-atomic particles to break apparently unbreakable... more... - Spaceweaver from Bookmarklet
