Will Artificial Intelligence Ever be Able to Discern the Truth?


















The following is simply a comment I first attempted to post in response to a piece written in the blog Dialogos of Eide. However it appears that as has happened one time before with another blog the comment was automatically rejected by the anti-spam filter which is now a standard component of Blogger. Although this leaves me somewhat frustrated it indicates to me that the dream of creating artificial intelligence is of yet to be realized if not impossible.

Hi Plato,

As you say in Plato’s conception the guardians would be deemed being so solely on the basis of ‘
merit’, which would have this employment of meritocracy to form the bases of both governance and general guidance. However it has always been a question for me what Plato thought ‘merit’ to be, that is as it is now mostly considered in the west or rather as it is thought of in the eastern conception.

I consider this important as I find if the former be the case, than ultimately the lie if revealed would be to find that the components of society have no compassion at all, yet strictly having all as self serving; although indiscernible with only the use of metrics. However if merit is held to be as in the eastern conception, then the lines between self and others blur to the point of having no meaning, in which case compassion born of empathy need not be an act dependant on a lie, yet one necessitated by truth.

The thing being that Plato as revealed in his writings never referenced to anything being known as the “noble lie” and therefore I find it interesting to wonder if he was simply the first ‘’
objectivist or rather did consider quality as being inseparable from good. With all I’ve read of him I’m almost certain it be the last to be true, as otherwise the rest of his teachings would become illogical and if nothing else I find him certainly to be logical.

Best,

Phil

Mothers

On this day thoughts of our mothers come to mind, which lends a sense of gratitude for those who are responsible for each of us finding ourselves in the world; that in it holding so much meaning as to what is born out of a hopeful continuance of existence and purpose. So I would like to thank all the mothers of the world today, along with the one who has them best represented of all; being the Mother of Invention.

From Where Springs Hope?










I so love spring, as with it comes the promise and demonstration of renewal. That as it marking the time for us to leave our fortresses of safety and solitude, as to venture out once again in search of the joy found only in discovery. It has often been reminded that hope springs eternal, yet so often forgotten that spring itself is the harbinger of hope, with having us all as its harvesters to benefit.

Taking a Swing at How to Improve Science






The following is in response to a post made by a commenter on the blog Backreaction. It was inspired by a proposal made by another of its commenters. I post this as being somewhat of an experiment, but mostly as to not clog up the aforementioned blog with my spontaneous and arguably simply whimsical thoughts:-)

Hi Andrei,

This may seem as to be a silly response for one such as you, yet it is resultant of finding I had a little time on my hands, which allowed me to read more carefully the exchange you had with Bee and some others. What confuses me in all this, is that you haven’t actually addressed the central tenet and concern expressed by Dr.Charlton. That was of course how we might identify those few individuals he considers being the ones more likely to make ground breaking discoveries, when nurtured properly and afforded a more suitable environment. What you seemed to have actually addressed is what constitutes to being good scientific direction and citing our current one not representing as being such.

There was some reference made to Kuhn and alike, who addressed the historical aspects of discovery in science, yet not so much the characteristics of those who are the most successful at it. In the end however I see both concerns having simply little relevance, as long as what’s defined as being science hasn’t changed too drastically since the time when Bacon and Descartes first outlined as to what this actually is. I myself have not found anything particularly different in modern times, from those of its beginnings, where of the theories proposed, the only ones accepted as true extensions of our understanding of the physical world, would be those supported by experiment, which corresponds to prediction. . For instance I’m not aware of any theory of quantum gravity developed having been accepted in such a context.

Instead of you addressing the question at hand, you changed the focus to raising your own contention, being that sciences suffers due to the researchers being pampered and cared for too much, with this in turn lowering their ambition and quality; leaving most content as being comfortably sustained, while only achieving mediocrity at best. I however find more reason to agree with Bee's perspective on this and yet would go further still . So, what's found in following being what that might entail. This I will attempt to explain with the aid of an analogy, which I find to be appropriate. This analogy is to compare how golf was improved by way of its golfers, through changes in it structure and organization, with how to improve science by way of its scientists with the same. I know it may sound unrelated, yet bare with me.

So to begin, if we look at the history of golf we find it had its beginning as simply a game, created to be enjoyed in the context of improving one’s own ability, in the background of competition. Later their where prizes offered for the winners of some of the games, first individual matches and then tournaments, for which the rule then was only to the victors go the spoils. However, as time progressed it was realized there was interest growing in this by a increasing sector of the populous and as such money to be made. Therefore, to optimize this potential it would be necessary to increase the number of skilled golfers and raise the level of competition. To accomplish this, a more effective method needed to found, which today in North America is the one created and administered by what became the PGA.

Subsequently, this body created a predefined number of assured tournament eligible spots, for which to be awarded one it is required to learn the basic skills, followed by both improving and proving yourself through some layers of advancement confirmed by test and competition.. These spots however are not made permanent and require one to maintain and improve ones level of skill, measured in terms of how successful one is from year to year that would entitle one to maintain being eligible.

Next, it was decided that through the course of the season it’s no longer the rule that the winner of each tournament is the only one to receive a reward, yet it is divided such that the winner receives the largest and most significant share, followed by a progressively diminishing portions, decided according to torunament placement, some going to all players who had made the cut for each tournament. What it amounts to is that although the best of all the players make the most money, nearly all who maintain their status as a player make what many would consider as being a very good living. The end result is the skill and performance of the players today is at an extremely high level. Also, the game over time has improved and continues to improve rapidly, which in turn has increased public interest allowing for further growth.

So you might ask, what does this all have to do with the success of science, by way of its scientists, in regards to its own corresponding structure and control? I think it can be already recognized there are many parallels between golf and science, starting from its beginning as something that was first only pursued from a personal gratification/growth perspective, progressing to where it is now a professional endeavour. The recruitment, training and placement also have much in common, as is the number of positions available and what’s required to assure and maintain one. The only exception to this is the practice and awarding of tenure, which has been argued is something to be perhaps only reserved for those who teach as well as add to the discipline..

The question to ask then is, why it that while golf and science appear as having so much in common, relating to its beginning and development, golf has enjoyed so much more relative success? Some might suggest as reason, that there are only certain heights one can reach and perhaps these are already being approached in science. However, the same could be said for golf yet it continues to grow. I would further contend if science has neared the limit, it certainly hasn’t yet delivered what we all thought it capable of or expect, so that’ can’t be it.

No, rather I find it rests with three subtle, yet distinct differences. First being the money that scientists can make by those that contribute (discover) the most, is nothing compared with what one receives via the victories of golf and more so those that are the backbone of it all make far less than the average tour player.. Second, when you compare the general interest in golf, with that of science, again golf is far ahead in this regard , which in turn results in increasing the number of golfers, swelling the pool from which to select for the professional ranks; as well as generating additional revenues for the ones that do become professionals. Finally, the public recognition of a professional golfer to that of a scientist is again not even comparable and as such this has the scientist’s true value downplayed from what it should be in the greater view.

So it is clear to me several things are required to change this for the better. The first being we need to substantially raise the general awareness and interest in science, as to have it seen as a valuable, challenging and rewarding (monetarily and or personally) human endeavour. Next, we must strengthen the ranks of the professionals by greatly increasing their remuneration and program funding, with more for those that prove successful, reaching levels that would seem almost unimaginable when compared to the current ones (books and personal appearances not included) :-) . This would include as in golf having the average professional financially sustained at a level that properly defines their place and necessity in the whole scheme of things; with it consequently being something seen as to encourage them to work hard to maintain, while in turn having greater room for improvement.

In addition, the time periods would have to be adjusted to afford a reasonable period in which to achieve result(s).. Considering that a PGA player gets another year if they only stays within his current predefined range and further given two years for winning one single tournament. Therefore, with all things considered, I don’t see why a researcher's initial contract shouldn’t be three years, with any significant result fetching an immediate five year extension. When it comes to heads of faculties, if required at all, I think this concept should be diminished or altered as to emphasise the importance of result, over that of seniority or long past achievement This would serve to have things remain dynamic, instead of becoming static. In the end however, it is the change in perception all this brings that is the central difference maker and therein somewhat ironic in it being something most scientists otherwise would dismiss out of hand, being considered as merely subjective:-)

To conclude you might say why didn’t I use a team sport as an analogy or corporate structure? The reason being I still would contend that even today, true significant advances and breakthroughs are the product of a final push by individuals or sometimes perhaps small groups. Yes, they are dependent on their peers, for direction, new concepts and inspiration, yet it’s that push, composite of their own intelligence, effort and fortitude(and yes at times a little luck) that in the end has them succeed .

Best,

Phil

Quantum Mechanics for Beginners












(image as posted in Wikipedia)


This is a response to a query a fellow made on BackReaction which I’ve taken the liberty to address here rather then clog up the space as it is in regards to an unrelated matter to the mentioned post. However, in as my interest in the question supersedes what I perceive as the true motivation for the query I offer the following.

Dany asks:

“Please suggest sequence of three books (time ordered) best suitable for the beginner to grasp QM (independent or tutored learning)”

For basic (non relativistic) QM, disregarding the math prerequisites, I would say perhaps the following:

  • (1) The Feynman Lectures on Physics-Volume III (Feynman-Leighton-Sands)
  • (2) Quantum Mechanics and Experience (David Z. Albert)
  • (3) The Undivided Universe (David Bohm and Basil Hiley)

If on the other hand one only wants the whole thing as just the facts and nothing but the facts, you can simply read Bohm’s initial primer on the whole subject - Quantum Theory. However, since just after writing this book Bohm was prompted to come up with a clearer explanation I view this book more from of a historical perspective rather than an explanative one.

Time, Mind, Body & Soul




As a consequence of recently being exposed to a wonderful blog, written by couple of married (to each other) physicists, I was lead to an interesting group of discussions pointing out changes of mind that certain contemporary intellectuals have had recently. In reading them I came across two, that not only interested me, yet also seemed to correlate as to my present way of thinking, from both my own scientific and philosophical perspectives. What you find here is as it is to be found as a comment I left on this blog and continues as follows (I take the liberty here to clean up a few mistakes I originally made):

The articles you point to on the changes of mind, truly are both interesting and indeed thought provoking. Two in particular now will have me go into one of my own protracted wonder modes. The first is a quote taken from that of Lee Smolin, who of course is one of Perimeters Institute's leading and founding researchers. He is referring here to his change of mind as to time being merely an illusion. He sums up his thoughts as follows:

“It is becoming clear to me that the mystery of the nature of time is connected with other fundamental questions such as the nature of truth in mathematics and whether there must be timeless laws of nature. Rather than being an illusion, time may be the only aspect of our present understanding of nature that is not temporary and emergent.”

I must admit that I share Smolin’s thoughts in regards to this. That is not that I should be compared as to fully having his depth of understanding on the matter. Einstein himself wrestled with this and once when asked if he thought that it could be simply as Smolin first thought said (I have paraphrased):

“It all could be an illusion, yet if so, it is a stubbornly persistent one.”

The second one is that of the change of mind of Todd Feinberg (Professor of Psychiatry and Neurology, Albert Einstein College of Medicine in the US). Here is expressing his change of mind as to whether a human being possessed a soul. As taken from the article, he previously believed that the notion of a soul was a fanciful religious invention. However, he has had a change of heart in saying:

“I have come to believe that an individual consciousness represents an entity that is so personal and ontologically unique that it qualifies as something that we might as well call ‘a soul’.”

Although he has come to this new way of thinking, he qualifies this in adding, that although convinced that the brain and the mind could be regarded as separate, though dependent, entities. He reminds that the soul dies with the body. This also is something that from a scientific and philosophical perspective I have also struggled with for years. My current line of thinking, although not exactly the same as his, runs pretty close.

The interesting thing for me is that Dr. Feinsberg’s position could be slightly modified by that of Dr. Smolin’s. That modification would be that time, if truly one aspect of nature proven not to lose its status as being a true aspect of reality and that reality is that of Einstein’s, insisting that time being a dimension. Then any one part of this dimension would also have permanence of sorts (as any part of a dimension would have). In this way, Dr. Feinsberg’s soul, although not immortal in the usual sense, could be at least permanent in the context in which Dr. Smolin suggests. I know all this is mere conjecture and a conjecture as science considers is nothing until empirically supported. It is however interesting to imagine that this too one day may also be decided.

Christmas Bohmian Style




In the spirit of the season I have recently come across a “conventional quantum” explanation of Santa’s delivery of presents to children on Christmas morning and how this in a quantum sense could all be done in the space of one night. Below find this explanation written by Sean Smeltzer, Croydon, Surrey; published in the journal New Scientist, January 16, 1999:

"QUANTUM CHRISTMAS"

I have recently received a number of distinctly unfestive emails pointing out the impossibility of Santa Claus delivering presents to all the children in the world in just one night.

We are all aware of the flaws in the conventional Santa Claus theory, but seem to accept it quite readily. Children are not quite so gullible and require a more rigorous proof of his existence. The answer to this problem lies in quantum theory.

Consider this: On Christmas night, Santa is in a superposition of quantum states, smeared out all the way around the planet, and each quantum state delivers presents to a single child. This explains why is is so important that children are asleep, because if just one child sees Santa, he immediately collapses into a single state, in accordance with Heisenberg. This would mean that no other children would receive presents that Christmas. This theory elegantly avoids all the flaws in the conventional theory. The only problem is that you will have to explain quantum theory to your children before you tell them about Santa.

After reading the above, I thought to myself; how could this all be looked at from a Bohmian’s perspective? I therfore offer the following:

A Bohmian’s Quantum Christmas

Santa delivering presents is a “quantum potential”, not merely just a possibility. A quantum potential is not realized, yet rather actualized without the need for observation. Many children accept this aspect of potential and thus it is actualized for them. I also would wager that children and others could more readily understand how all this works, as opposed to the quantum algorithm (lest I say fairytale)

As one can see this is by far a more straight forward and consistent explanation as opposed to the first and as I maintained could be actually understood. It also has the advantage that observation plays no role in the actualization of the event at all and better explains why, no single, or any child’s observation of Santa has ever spoiled Christmas:-)
