The great money experiment

Cash, an ancient form of monetary value facilitating transactions, is still dominant in most parts of the world. Initially, cash represented precious objects, an idea that forms the foundation of the gold standard, yet another archaic concept pursued by those who do not know that the world has changed. More recently, the English East India Company, that minted coins to send to the East to buy spices and borrowed the term "cash" from Sanskrit, may have been solely responsible for the adoption of cash across the empire. It is only apt that India is getting rid of "excess cash," the source of corruption, tax evasion and terrorism.

Paper money has substantially expanded monetary incompetence across the globe. If electrons can count and fly across the globe instantly to account for credits and debits, it is unclear why humans carry metal and paper in their pockets to transact. Bad habits die slow and in a world that does not barter, cash was a crutch, that is no longer needed. Those who say politicians lack vision should look East, albeit, it is a singular experiment that breaks open new possibilities. Physical forms of cash has been inefficient, archaic and problematic for centuries but none had the guts to get rid of it. To time such a catastrophe, when the eyes of the world is transfixed on the other side of the world, is pure genius.

Yes, the unexpected policy change is going to bring tactical strife to a billion people, except those who had some early warnings to move their "excess cash," to Switzerland. But it may still be utility maximizing for a country that is becoming the largest in the world with a population languishing without technology and information. The prime minister appears forward  looking but it is going to take more that a few trips to Google, Microsoft and Facebook, to prop up a country that seems to have lost its way. Sure its engineers and doctors are sought after but the soul of the country, struggling to find its place, has failed to instill confidence to propel it beyond the third world status, it has been afforded.

Getting rid of corruption and excess cash is the first step. But to go further, India has to provide technology and information to its masses in an architecture that is based on free markets and free trade and not what its socialists leaders proposed from inception.

Light Medicine

Recent research from the University of Bonn (1) that demonstrates light pulses are effective in jump starting a dying heart, opens up a long neglected pathway of electromagnetic spectrum in the treatment of diseases. Medicine, dominated by chemistry for many centuries, has been languishing. The complexity in the biology of humans, a haphazard combination of mistakes and happenstances has given those with an engineering mindset, hope. But they have been slow to recognize that the beneficial effects they find by the introduction of finely tuned chemicals are often followed by unknown, unanticipated and uncertain toxicity. Such was the domination of chemistry in medicine that they delegated physics to mere diagnostics. However, ancient cultures have been more aware of the effect of magnetism and light on the human body, albeit by unsystematic and unproven guesswork.

A new dawn is close at hand in which physics and computing will propel human health to hitherto unknown levels. We may finally recognize that specificity of intervention that is often accompanied by toxicity in chemistry is not the case in physics. In fact, it is just the opposite. The particles that propagate light and magnetism could be finely tuned and directed to the compartment of the human body that is not performing as expected. Once humans master the quantum effects exhibited by these particles, they may be in a position to hold and impact microscopic parts of the human body without pain or loss of control. The light defibrillator is exactly in this vein that spares the patient from any level of discomfort as it restarts the organ attempting to take a break.

The convergence of medicine and physics is a welcome trend. As the theoretical physicists struggle with beautiful but unprovable fantasies such as string theory or spend most of their careers measuring things they have no clue about such as dark matter and dark energy, perhaps they can devote a few hours of their time to something more practical. If they do, it can change medicine and dethrone ideas we have been pursuing from the middle ages.

Missed by a whisker

As the string theorists work out the mathematics of the "theory of everything,", as the particle zoo keeper adds yet another particle to the compendium of knowledge, as the space agencies and private companies clamor to dominate space and send humans to Mars, as the environmentalists lament about the impending gloom and doom and as the activists burn and pillage to redirect policies, a large asteroid passed by the Earth peacefully, missing it by a mere 300K kilometers last night, a literal blink of an eye. And more, a lot more, is in the channel heading for the blue planet. I wonder why there was nothing in the news about it.

Humans habitually worry about the tactics and forget the big picture. There is an evolutionary basis for this as most of their history has been about tactical survival. The African Savannah was not a friendly place and as she descended from the trees, she exposed herself to danger all around her. The human psyche, thus, is programmed to worry about tomorrow and not next year for the probability of the later having any meaning for the individual was low. As the "Nobel laureates" attempt to mend the environment, they have to at least understand that the likelihood of Earth surviving a hit by a reasonable sized asteroid is small. And, there are an unimaginable number of objects in the splintered neighborhood of the solar system. The failed star, Jupiter, does her best but sweeping up all the dangerous objects that shower down from beyond her is almost an impossible task.

Those with a few billion $ to invest to create a "legacy," may be best advised to analyze the risks and rewards of their investment choices, Sure, creating a "space colony" and "curing death," are indeed great ideas but if they want humanity to survive (without whom their "legacy," will have no value), they may need to focus on something entirely different. Those who have been chasing "singularity," may need to consider that even "Artificial General Intelligence," will be dead and gone by the physics of impact. Creating robots of immense talent is good, but protecting a fragile environment built over five billion years may be more valuable.

It will be indeed ironic if the "advanced humans," are wiped out by a similar incident that lend mammals, an opening to dominate.

Live forever?

Recent findings that appear to indicate that aging can be stopped in mammals by starvation and possible introduction of simple chemicals is encouraging for those who may want to live longer. Humans, a plumbing system designed by bacteria to consume and dispel nutrients favorable to them, have found it difficult to sustain life beyond thresholds established at their inception. Anti-bacterial agents did extend life tactically by a decade or so but it appears that they are hitting against some hard constraints. Engineering systems, specializing in plumbing tasks, have limited life and humans appear to fall into this category.

Although humans carry a specialized quantum computer on their shoulders, the action has largely been in their gut, thus far. A crude tubular structure, able to break down a variety of materials to feed its occupants, has been the main design feature. But just as any other such mechanical designs, the scaffolding deteriorates over time and the structure itself loses flexibility and crumbles after certain number of cycles. So, it is not surprising to imagine that life can be extended by starvation as that will reduce the number of cycles imparted on the most important aspect of a human - her gut.

The more important question for humans is what they are likely to do with a possible extension of life. Would they use the extra time to seek knowledge or fight with those who do not look or think like themselves? Would they use the extra time to advance society or segregate themselves into neatly fractured boxes? Would they look forward or be encumbered by their past, driven by simple objective functions? Would they attempt to create and leave a legacy or understand that legacy is meaningless in an advanced society? Would they attempt to understand themselves or be misunderstood forever?

Extreme skew

Over 100 billion humans lived on the earth since they have arrived hundred thousand years ago. However, most of the fundamental knowledge they have gained from fire to quantum mechanics over this time period came from an incomprehensibly few number of people, perhaps as few as 100. This is a hard constraint for humans to advance knowledge as it depends very much on the arrival of a unique individual, perhaps in a few generations. Increase in abstract and fundamental knowledge does not seem to depend on anything else except the presence of that special individual who propels humanity across a discontinuity. Forecasting of knowledge progression in such a regime that follows a smooth stochastic evolution with an extremely small probability of a jump, is a futile exercise. 

Why is this the case? The variation in intelligence across humans appear very small and their physical abilities as good as perfect cloning. But a single person out of one billion appears to possess special powers, albeit all measurable characteristics of that individual are within expected norms. If the probability of this error solely depends on quantity and not on time, then, there could be as many as 7 such individuals who could be present in today's world. This does not seem to be the case as there has been little advancement in fundamental knowledge for close to hundred years.

Systems that exhibit time based errors are similar to electrical systems such as computers and not mechanical systems that can move. The hundred errors seen over 100 thousand years appear evenly spaced in time and show no acceleration in the presence of much larger number of contemporary experiments. If these errors were part of a natural process such as evolution, humanity would have produced a dozen such fundamental leaps in a single generation by now. However, all indications are that there is no difference in the arrival rates of the genius who changes the human mind.

If the universe were a rules based simulation or driven from a random initial state, then larger experiments will unambiguously lead to larger number of errors. It appears to be programmed to regime shift only with time, implying a game with possibly prescribed and controlled end outcomes.

Space contamination

Space agencies world over have been on a quest to send a feeble human out of the world and most likely to Mars. Now that the president has also joined the game, more investments will be going in that direction. And many private companies are on the same track as well. But is there any reason other than nourishing own ego to attempt a trip to the red planet?

Humans have ably demonstrated that they are incapable of taking care of the environment they live and breed in. To send a specimen of the human kind to another planet would be the first step to initiate an irreversible catastrophe. Some have argued that sterilization of robotic equipment travelling to other planets is overdone and even suggested that humans should seed any rock they can find with bacteria and virus. Sure, the single celled cousins may jump at the suggestion, but is that wise?

Exploration has been integral to the human experience. But history also shows that their explorations have resulted in irreversible damage to what they found. They have been unable to learn by observation and bad habits picked up in the past hundred thousand years invariably has led to scorched earth policies. Now that the horizons are expanding beyond the struggling blue planet, there is no indication that humans have learned from their mistakes.

God does seem to have a sense of humor as she appears to have imposed daunting space-time constraints on a species who has acquired a quantum computer, by sheer accident. To make matters worse, the canopy, humans could observe is infinitely bigger than they could ever experience and akin to an ironic twist in a horror movie, they find that such observations are fleeting as the whole universe runs away from them at an accelerating rate.

Those who sit back in awe of the abundance of ignorance surrounding them, often have no desire to drive the truck to the next planet. But the engineers among us live for such meaningless tactics without ever thinking what it really means.

How long?

A recent survey from Columbia (1) shows some interesting results. They asked 1600 participants between the ages of 18 and 64, how long they prefer to live. It appears that close to half of the surveyed population would not want to live more than the average life expectancy and almost 1/6 indicate a preference lower than that. Beyond the obvious correlation to expectations of the quality of life in old age, the data also shows significant relationship to race - with African Americans and Hispanics wanting to live a lot longer than White/Caucasians.

This is an important question and a rich area for further research. Till recently, humans had conquered most of the pathogens but they succumb to auto-immune diseases in which the body attacks itself. Heart disease, cancer and diabetic complications top the list - all of which portend lower quality of life in later years. This coupled with a brain that is bored could be a potent combination for humans, whose infrastructure was never designed to go beyond a few decades. In spite of the billions going down the drain to “cure all diseases,” it is clear that homo-sapiens may require outside help to get over their genetic deficiencies.

How long does one want to live? I think it should depend on whether one is able to add value to society.

Sugar & Salt

For nearly hundred thousand years, humans were without two ingredients that will cut their life short substantially. In the last few thousand years, sugar and salt rose to prominence and are now considered responsible for a large spectrum of human diseases including heart disease and metabolic syndrome that includes diabetes. The economics of these chemicals has been attractive from inception. Recent evidence that the sugar lobby (1) has been involved in suppressing the evidence that sugar played a major role in CHF is symptomatic of the fact that there has been powerful forces behind these industries. Little did Gandhi knew that his salt march in India, nearly a century ago, could have been deleterious to the health of Indians.

The taste buds of Homo sapiens are finely tuned to pick up these toxins, for small quantities are absolutely essential for health. The evolutionary forces could not anticipate that these chemicals will be manufactured and consumed by modern humans in such frequency and quantities that their organs simply give up, unable to cope with them. These materials have become a sign of wealth and power and nations warred to take control of their sources and production. More recently, they have been disbursed in colored and famous water world over, to fundamentally transform human health. 

Two toxins, salt and sugar, are responsible for possibly half the health care costs in the world. However, there are no signs of any abatement in their production and consumption.

They are already here

As a chunk of investments go down the drain seeking extra-terrestrials, drug resistant bacteria that cause two million illnesses and 23 thousand deaths in the US alone (1), have gotten little attention. These true extra-terrestrials, who got here hitching a ride on an asteroid, have been powerful and robust over a few billion years. They have transformed the planet, oxygenated it and prepared it for larger organisms, that would fall prey to them. They could dance in unison, divide and multiply and evolve in short horizons, aided by almost countless experiments. They will create organisms that could walk and eat, to satisfy their every whim, with an intelligent control system, that "advanced life," calls the microbiome. They could trigger feelings, switch their occupants' brain on and off, get them to eat what they would like and even decide on an expiry date for the host. Such is the power of the single cell organism, they have dominated the blue planet since their arrival, perhaps by chance.

ET is already here and they have been for over four billion years. As the greatest scientists fear, they are indeed more intelligent as they have not only designed an environment for themselves but also populated it with organisms they could control for their own benefit. As the chemists seek soil from far and wide to conquer the fully optimized machines they could only observe under a microscope, as the pharmaceutical companies run away from declining economics of third world diseases, as the NIH struggles to figure out how to advance thoughts and action, as the foundations that proclaim to lift humanity from disease and strife stop at mosquito nets and commercials, the single cell organism organizes further to consolidate control.

The worst idea of human history is the thought that they are "advanced."

ROE - Return on Education

As the political season heats up, politicians appear to be mired in tactics, symptomatic of lack of vision and strategic intent. A society deserves the politicians they are afforded but increasingly policies that affect the long term health and prosperity of the nation are unlikely to be affected by the appointed leaders, whoever they may be. Some want walls and others Wall street, but neither can lift the spirit and ambitions of 320 million beating hearts across the continent. As space enthusiasts search for extra-terrestrials, technologists build artificially intelligent bots and medical experts seek methods to ameliorate pain and defeat micro-organisms - politicians, caught in a time warp struggle to stay relevant. The younger generation has left them, for they have seen the light at the end of the tunnel, where they could imagine and build a world for the future.

As the blue planet spins and rotates to stay alive from its perpetual plunge into the center of the sun, protected from countless debris by its venerable cousin, Jupiter, its inhabitants, blinded by ignorance, appear to be ready to fight. They fight with ideas, races, countries, localities, genders and the gender-less, as if their whole life depends on it. They shout on TV and against those on the idiot box, they soften and harden policies at will, they own and disown coal, make speeches to the top bankers for money, refuse to release tax returns and proclaim wealth without understanding there is a liability side to the balance sheet. They visit churches of color, dance to show approval only to break down a few minutes later. They seek money for charities funded by the straight and the crooked, they meet lobbyists and people, shake hands and hold babies as if the whole country is melting down at the sheer sight of them.

Politicians, possibly a new species, could be endangered species, especially if the world educates itself with freely available information. Education has the highest return compared to any other investment by an individual or society. It can help sort out fake politicians who assert their past and your future, confidence tricksters, non-replicatable academic studies, drugs that lose efficacy over time, financial advisers who do not know finance, advertisements that promise the impossible, religious fanatics who perform magic, insurance policies that do not pay, charlatans who shout buy and sell as markets close and space agencies who spawn manned space missions for their own sake.

Such is the state of misinformation that education has higher returns now than it ever had.

The stock and flow of IQ

A recent publication in the Royal Society Open Science (1), hypothesizes an intriguing idea - explosion in hominoid intelligence a few million years ago was aided by a significant increase in blood flow to the brain and not necessarily by an increase in its size. Moreover, the increase in the flow of blood may have resulted in the growth in brain size. If so, a lucky change in the diameter of the arteries carrying blood to the brain may be responsible for humans dominating the blue planet.

Plumbing appears to be central to health. It has been speculated that most autoimmune diseases, including even Alzheimer's disease, could be related to the body's declining ability to eliminate waste through the plumbing system, it has been afforded. Age and use of these systems appear negatively correlated with their efficiency in clearance. If the recent finding is true, the plumbing alone plays a central role in the evolution of intelligence, providing the energy hungry organ with ample fuel and cooling and nourishing it from relatively modest beginnings in Australopithecus to arguably better modern humans.

Plumbing appears to be central to modern medicine. In a regime with little threat from microorganisms, humans may perish by the clogging of their own aging infrastructure.

Proxima test

As the year 2020 draws near, those who emphatically professed conclusive evidence for extra-terrestrial life would be found by then, are getting a bit nervous. But there is good news - a rocky planet, Proxima-b, has been found in the "habitable zone" just a mere 4 light years away. All that remains now is the "contact," - or perhaps spectral evidence of oxygen, water and methane before uncorking champagne bottles. We are now months away from the declaration that life on Earth is not unique, albeit, by proxy evidence. The space agency, as usual, is ahead of schedule.

Boring statisticians have devised constructs such as prior and posterior probabilities of expectations - something ET enthusiasts appear to have little respect for. They have left Enceladus, Saturn’s beautiful moon, the most promising for life in the neighborhood, in the dust with the news that Proxima-b has been found, for conjecture is more powerful than facts and spectra, more beautiful than actual measurements. Before the space agency devises methods to test for life on Proxima-b, they have to ask two important questions.

1. What is the a priori probability of life on Proxima-b?
2. If they do not find life there, does the posterior change in any way?

If the answer to question 1 is zero or the answer to question 2 is no, then there is no logical reason to explore the rocky cousin. We already know there is no "advanced life," there because if there were, we would already have been at war with them.

The fifth force

Recent research from the University of California, Irvine, (1) speculates on the existence of the fifth fundamental force field, apart from gravitation, electromagnetism and the weak and strong nuclear forces. This is possibly in a newer direction that counters the tendency of contemporary physicists to spawn yet another "fundamental particle", anytime they do not understand a phenomenon. Speculating on the existence of a newer force, at the very least, shows some creativity in high energy physics, resting on the laurels of their recent discovery of the God particle, in the noise generated in Geneva.

It appears that we are in a stalemate. Physics, dominated by technicians, has been running amok, plunking billions down the tunnel, proving particles of fantasy. It appears that few are asking if proving fantastic particles is advancing the field in any way. Recently, the engineers hung mirrors to measure gravity waves to the tune of the diameter of a proton to prove two black holes merged nearly a billion years ago. Could somebody prove otherwise? Physics has reached a plateau, in which physicists can prove anything with the help of engineers.

Since we have over hundred "fundamental particles," already, perhaps defining a new "fundamental force field," is in a better direction.

Deeper learning

Recently, statistical and mathematical techniques that have been tried and abandoned decades ago to teach computers to be smarter, have surfaced again with better sounding names. With nearly zero cost computing power in the cloud, some companies have been plunging head first into the deep abyss. Deep learning is stylish - some even try "deep mind," in an attempt to replicate the complex human. What the younger scientists may not know is that most of what they have found, has been known for a long time and one should not take advancements, due to only the recent availability of cheap computing power and memory, as "ground-breaking." Disappointments may be in store for those, highly optimistic of "solving," human intelligence. The convergence of Neuroscience and Computer Science is a welcome trend, but a dose of realism may be apt medicine for those modeling the mind, downloading the brain and possibly curing physical death.

Even since she stood up in the African Savannah, a few hundred thousand years ago, the human has been puzzled by her own mind. She searched the skies, climbed mountains and dived into the oceans, seeking the object, she could not herself define. The theory of consciousness has eluded her, for what she was seeking obviously interfered with the tools she was using. It was the ultimate prize. If she could understand herself, then, a whole new world could open up. The body can be separated from the mind, and the latter then could be rendered immortal. The mind could be replicated and networked and perpetuated across space and time. She could create and capture imagination at will. She could solve problems of infinite complexity, travel into interstellar space or even to another universe. If only, she could understand the mind and concoct a theory of consciousness. But alas. it is not to be. Whatever one calls it, the "neural network," has failed to show signs of consciousness. Yet another technology is substantially sub-optimized by engineers and scientists, most comfortable with deterministic answers to complex questions.

Ignorance is highly scalable in the presence of infinite computing power.

Premature existence

Recent ideas from Harvard (1) speculate on the lack of  maturity of life as we find it on Earth. Contemporary theory, which appears highly unlikely to be true, suggests an origin of the universe about 14 billion years ago and the ultimate demise of it in about ten trillion years from now, making it infinitesimally closer to birth than death. Life, if it is a property of the system, has had only a short moment in this unimaginably long time horizon. So prototypical observations of life, such as that we find on this uninteresting corner of the Milky Way, a rather common place galaxy, is premature by any stretch of the imagination. Even after the Sun balloons up in less than five billion years to a red giant and consumes the blue planet, with all its ignorance locked up in a small space, the universe will continue and create life forms of much greater capabilities and interest.

Life on Earth appears to show severe limitations and indicate prototypical experimentation, with infinitesimal life spans of biological units, that appear incapable of perpetuating information and knowledge across time. Such a design can only be the result of an unsuccessful trial of a large number of possible simulations. The fact that "advanced life," is battling the microscopic ones on Earth can only imply very early and unsophisticated experiments to gather raw data. If there is any learning present in this prototypical system, it has to be about what does not work rather than the other way around. The fact that the blue planet at the exact distance from a medium size star with such abundant resources and stable climate has been unable to produce intelligence may instruct future experiments, what not to attempt.

It is early but known experiments appear to be in the wrong direction.

Biology meets computing

The ease of biological manipulation by chemical means has held life sciences companies back for over a century from exploring the system, that is equally receptive to electromagnetic interventions. Recent news that GSK has partnered with Alphabet to advance the field of bioelectronics is encouraging. The idea is to impart electrical signals to neurons by micro implants to cure chronic diseases. Although it is a profitable path to pursue, some caution may be in order.

There is a long history of engineering experts attempting prescriptive interventions on biological systems with an expectation of deterministic outcomes. Humans are generally good in engineering and traditional computing but biological systems do not behave in such a predictable fashion. Their engineering competence comes from selection, in which simple tools based on Newtonian Physics let them survive the harsh environment they were in for nearly hundred thousand years. The modern game is distinctly different and it is unlikely that they possess the skills to fast track with the hardware they have built up. With "Artificial Intelligence," soaking up the air waves, it is important for technology giants to bias toward humility. As projects such as "death cure," so slow to come to fruition so as to annoy the technologists behind it, perhaps getting not too excited about curing diabetes through neuron stimulation is a good idea. After all, nature took four billion years to get here, albeit, it was without a computer farm that soaks up a high share of the world electricity production. Competing with nature is likely to take a bit more than that.

The convergence of biology and computing is unavoidable. However, it is unlikely to be advanced by those with stagnant notions of either field.

The inverted U

The value individuals add to society appears to be in the shape of an inverted U. On the high end - philosophers, scientists and technologists, who seem to know everything, appear to add very little of practical value. Recently, a scientist remarked, "when we found the gravity waves, the whole world stopped," unaware of the fact that most of the world did not know or care. On the low end, ignorance is as dangerous as cyanide, as ably demonstrated by contemporary politicians. In this scheme, the highest value to society appears to come from those in the middle - not too ignorant and not too arrogant. On both ends, there is a common factor - a brain that is idle, because of either stupor or conceit.

To maximize the value that individuals contribute to society, it appears that they have to be lifted from the abyss of ignorance or shown a practical path down from the mountains. The perception of knowledge is as dangerous as a lack of awareness of ignorance - for both result in a loss of value to society by a lack of contribution. The former, locked behind ivy walls, lament at a world of ignorance and the latter, aided and abetted by their leaders, scorn at knowledge. In the middle, humans of blood and flesh, are caught in a time warp they simply could not escape. Apathetic and lethargic, the middle withdraw from media events and elections and watch from the sidelines. This is a movie with a sad ending - dominated either by the ignorant or the arrogant, with little to differentiate between them.

Neither abundance nor lack of knowledge add societal value. Those who are aware of their limitations, do.

Simplified diagnostics

Research from Columbia (1) indicates that impairment in odor identification portends cognitive decline and possibly Alzheimer's disease. This appears to dominate more prevalent PET and MRI scans for the diagnosis of these ailments. This is a constant reminder that humans are far from mastering the workings of the organ they carry on their shoulders by engineering and scientific means and simpler measurements of inputs and outputs dominate such mechanics.

The human brain has been an enigma. It consumes vast amounts of energy and often produces little utility - either to the immediate host or to society at large. It effectively delegates routine affairs to the vast Central Nervous System attached to it by a thread and maintains a small garbage collection mechanism within itself to keep track of the estate it manages, automatically. Often, it gets bored and shows signs of over-design, a quirk of evolution that endowed it with vast processing power by incorporating quantum computing in a small and efficient space. Lack of large memory has allowed it to venture into the production of heuristics and showing signs of intelligence. But acceleration in technology and society has stretched it, lending some functions of importance irrelevant and elevating the irrelevant to importance.

Its decline is painful to close observers but not necessarily so for the host, herself. In a regime that disallows rolling back time, the objective function has to be minimizing pain - physical or emotional. A system that pragmatically allows such an outcome by its own deterioration can only be considered good. Diagnostics that does not require cutting open the delicate organ or injecting it with radioactive materials may be the best, for the recognition of the start of decline of this beautiful machine is not necessarily good for the host nor for close observers.

Shining a light on a black hole

Research from the Moscow Institute of Physics and Technology (MIPT) (1) hypothesizes a measurable and elegant difference between a black hole and a compact object. The event horizon of the black hole, defined by the Schwarzschild radius, is significant - anything slightly bigger shows fundamental differences in behavior. A beam of scattered particles shows discrete spectra in the presence of a compact object that escaped collapsing into a black hole. If it were a black hole, it will be in a constant process of collapse, with a complete stoppage of time for an external observer, resulting in a continuous and smooth spectra.

The concept of a black hole has been an enigmatic thought experiment for physicists and amateurs alike. Contemporary theory fails in the singularity and speculates a stoppage of time inside the event horizon, something that cannot be fully envisioned by humans trained in the practical regime of Newtonian Mechanics. A black hole will never stop collapsing from an external perspective and so there cannot be any ex.post question on a black hole. Theories that attempt more detailed explanation beyond the event horizon is fantasy - just as the mathematically elegant string theory that cannot be tested. In spite of all the engineering progress in the last hundred years, fundamental understanding has remained akin to a black hole - in suspended animation. A handful of men and women from the turn of last century remain to be responsible for most of the abstract knowledge that humans have accumulated. The reasons for this is unclear but lack of imagination appears to be the prime suspect.

Fooling around with mathematics may give contemporary scientists satisfaction but explaining the stoppage of time will require more than that.

You are what you learn

Recent research from MIT (1) shows that the underlying attributes of music – consonance and dissonance – are not hard wired. Contrasting preferences of tribes with little exposure to Western music such as some Amazon tribes and those with gradually increasing exposure, culminating in accomplished American musicians, they prove that the preference toward consonance over dissonance is learned. Music, thus, appears to be personal and preferences largely generated by experience rather than an innate mechanism in the brain.

In the contemporary regime of accelerating data, the brain is bombarded with an information stream, it was never designed to tackle. An intricate quantum computer, specialized in pattern finding but with rather limited memory, the brain has been stretched to undervalue its advantages and it has been struggling to keep large swaths of data in its limited memory banks. The learning processor, however, has been able to efficiently design and store information in heuristics and dump the underlying raw data as fast as it can. As it loses history, the stored heuristics drive function and generate preferences, as if they are part of the original operating system.

The finding has implications for many areas not the least of which is in the treatment of Central Nervous System (CNS) diseases such as racism, alcoholism and ego. Fast discarding of underlying information due to a lack of storage capacity, prevents back testing of learned heuristics. A limited training set of underlying data could have irreversible and dramatic influences on end outcomes. More importantly, a brain that is trained with misguided heuristics, cannot easily be retrained as the neurons become rigid with incoherent cycles.

You are what you listen to, you are what you eat and more importantly, you are what you learn.

The failure of finite elements

Engineers and mathematicians, with a core competence in building complex structures from elemental and standardized components, have had a tough time with domains not amenable to prescriptive and deterministic logic. These include high energy physics, biology, economics and artificial intelligence. The idea that the behavior of a system cannot be predicted by its components is foreign to most disciplines and the applications of such hard sciences, supported by engineering and technology.

In complex organisms such as companies, it has long been recognized that outcomes cannot be predicted by an analysis of its components, however standardized they may be. The “rules of engagement,” if not defined in elegant and closed form mathematics, appear to be less relevant for those seeking precision. However, there is almost nothing in today’s world that could be defined so precisely and the recognition of this concept is possibly the first positive step toward embracing reality.

The interplay between physicists wanting to prove century old predictions and engineers standing ready to prove anything by heavy and complex machines, has been costly to society. The interplay between biologists and chemists wanting to influence systems with precise and targeted therapy and engineers standing ready to do so, has been costly to society. The interplay between economists looking to apply statistical precision to the unknown and engineers ready to build models to whatever is needed, has been costly to society.

Complex systems cannot be broken down to finite elements for the behavior of the system does not emanate from its components.
