Atomic Adventures (Secret Islands, Forgotten N-Rays, and Isotopic Murder-A Journey into the Wild World of Nuclear Science.)

By: James Mahaffey

Narrated By: Keith Sellon-Wright

James Mahaffey (Author, Research scientist at Georgia Tech Research Institute)

“Atomic Adventures” is a reminder of the race for the atomic bomb, its wide pursuit by nations of the world, and research for the holy grail of atomic fusion. Mahaffey’s science explanations are tedious for non-scientists, but his history of the secrets and use of atomic energy are interesting and surprising.

The United States, with the help of the UK, may have been first to acquire the atom bomb in 1945, but eight more nations acquired it by 2006.

United States: Acquired in 1945.

Russia (formerly the Soviet Union): Acquired in 1949.

United Kingdom: Acquired in 1952.

France: Acquired in 1960.

China: Acquired in 1964.

India: Acquired in 1974.

Israel: Believed to have acquired in the late 1960s, though it maintains a policy of deliberate ambiguity.

Pakistan: Acquired in 1998.

North Korea: Acquired in 2006

It is somewhat ironic that Pakistan did not acquire the atom bomb until 1998 when Pakistan’s “father of the bomb”, Abdul Qadeer Khan, became a rich man by selling technological know-how of the bomb to nations like North Korea, Libya, and Iran.

Abdul Qadeer Khan (1936-2021, father of Pakistan’s atomic weapons program, died at age 85.)

As a singular discovery, Einstein’s E = mc² offered a dual opportunity for the world, i.e., destruction and/or survival of the human race. The bomb suggests destruction while nuclear fusion offers an inexhaustible energy source that could reverse global warming and rocket human beings to other worlds.

ALBERT EINSTEIN (1879-1955, died at age 76.)

Mahaffey explains the immense potential of nuclear power as a principal source of energy. History shows nation-state and political conflicts may spin nuclear power out of control to kill millions and devastate the environment. On the other hand, nuclear research and power offer avenues for humanity’s survival and longevity.

Mahaffey notes there were Japanese, as well as better known German scientists, who were working on the creation of a nuclear bomb that could destroy Allied armaments and combatants. The rush to weaponize radiation during WWII surprisingly includes research being done by Japan as well as Germany during WWII. America won the research race because of superior human and financial resources that could be marshalled to complete the scientific research and experimentation needed to perfect a nuclear weapon.

Mahaffey explores the creation and destructive history of the atom bomb.

Surprising to some listeners, Mahaffey explains Argentina’s significant effort to increase its research and development of nuclear power after WWII. Argentina created the National Atomic Energy Commision in 1950. The chief researcher, hired by President Juan Perón, was Ronald Richter (1909-1991), an Austrian-born scientist who headed their plan to create a fusion power facility. Richter fails but nuclear energy remains an important part of Argentina’s history. In the 1960s they built their own research reactors and by 1974 built their first fission nuclear power reactor, Atucha I. By 1984, they had two heavy-water reactors with Atucha I and Atucha II.

Ronald Richter (1909-1991, Austrian-born German who became an Argentine citizen who headed up the Argentine Huemul Project to create a nuclear fusion power plant. He failed, despite the millions of dollars spent to build and rebuild fusion power plants.

Yoshio Nishina (the father of modern physics research), Bunsaku Arakatsu, and Masatoshi Okochi created the so-called Ni-Go and F-Go projects to develop an atom bomb. They did not get beyond the laboratory stage because of a lack of resources, the exigency of war, and the complexity of nuclear technology. The energy of nuclear power, as shown by history, is two edged.

Yoshio Nishina (1890-1945, the father of modern physics research during WWII.)

On the one hand it can be used to purposely or accidently destroy humanity.

On the other nuclear radiation can heal the sick

and potentially provide a clean renewable energy source.

Mahaffey explains how research in fusion can go awry. In a news article, two chemists reported in 1989 that fusion was created in their experiment by involving heavy water (deuterium oxide) and palladium electrodes. They reported excess heat production that they believed was nuclear fusion. As with all scientific experiment, their results had to be confirmed by other scientists testing of their results in the same experiment. Mahaffey, in his role at the Georgia Research Institute, was asked to replicate the experiment. Using the same tabletop experiment, Mahaffey initially confirmed Fleishmann’s and Pons’ findings. However, no other table-top experiments found the same results. What Mahaffey finally found was that the neutron counting device that was recording increased heat was the actual source of the heat increase, not the chemical interaction between heavy water and palladium electrodes. Further research is being conducted but the U.S. Department of Energy concluded in 2004 there is no convincing evidence to support cold fusion. Tests are still being done but Mahaffey infers that research is a scientific dead end. Mahaffey and a colleague tried again in a basement of his colleague’s house to try a similar experiment and failed.

Nuclear power has the potential to revolutionize interplanetary travel. The higher efficiency and power, particularly with the perfection of fusion, will shorten travel times and make trips to Mars and beyond more feasible.

Mahaffey explains how communication will be a challenge when interplanetary travel becomes common. The distance to other planets or galaxies will impede communication because of the limits of the “speed of light”. However, the solution may lie in quantum entanglement’s experimental proof found by Clauser, Aspect, and Zellinger. The complexity of entanglement makes the theory unprovable at the time of Mahaffey’s book.

In theory, quantum entanglement suggests information (communication) may be instantaneously transmitted across galaxies without the limitations of the speed of light.

Mahaffey goes on to explain the risk of radiation in a chapter about a “dirty bomb”. Security measures used to protect the public from radiation leaks make thieves believe something valuable is being secured by government laboratories. Thieves will steal these secure containers only to find they are risking death by opening their booty. Additionally, Mahaffey notes radioactive material is often disposed of illegally and irradiates innocent people who own dump sites that received inadequately contained radioactive material.

BELIEF

Extending Harari’s idea of biophysics research and algo-rhythmic programming suggests a potential for immense changes in society. A singularity that melds A.I. with human brain function and algo-rhythmic programming may be tomorrow’s world revolution. Of course, that capability cuts both ways, i.e., for the good and bad of society.

Homo Deus (A Brief History of Tomorrow)

By: Uval Noah Harari

Narrated By: Derek Perkins

Yuval Noah Harari (Author, Israeli medievalist, military historian, science writer.)

By any measure, Yuval Noah Harari is a well-educated and insightful person who will offend some and enlighten others with his opinion about religion, spirituality, the nature of human beings, and the future. He implies the Bible is a book of fiction that is historically proven to have been written by different authors with contradictions that only interpreters can reconcile as God’s work.

“Homo Deus” is a spiritual book suggesting humanity is on its own and has a chance to survive the future but only through the ability of human understanding and effort.

To Harari, the greatest threats to society are national leaders who believe in God, heaven and eternal life who discount human existence and use of science to improve human life on earth. The irony of Harari’s belief is that humanist leaders are the only hope for human life’ survival.

Harari argues science, free enterprise, and the growth of knowledge offer the best hope for the future of human life.

Neither capitalism nor communism are a guarantee of survival because of the increasing potential for error as human beings become more God-like. Advances in engineering, artificial intelligence, and biotechnology may replace the happenstance of human birth. The value of free enterprise is evident in the agricultural, industrial, and technological revolutions of history. However, as science improves the understanding of the mind and body of human beings, the technology of biogenetics offers hope for the future while running the risk of biological error with unforeseen consequences.

Harari’s book is the brave new world written about by Shakespeare in the 17th century and reimagined by Aldous Huxley in his 1932 dystopian novel “Brave New World”.

On the one hand, Shakespeare offers a positive spin as his character, Miranda, sees people from outside her experience and says “How beauteous mankind is! O Brave! That has such people in’t”. While Huxley notes a future society that becomes conformist and lacks individuality and human emotion. Which way society will turn is unknown.

Harari argues capitalism is the best hope for continued scientific innovation because of the incentive it creates for exploration of the unknown.

The conformist demands of collective ownership of property and means of production by communism impede creativity. Capitalism is more creative and dynamic. However, capitalist incentive raises the specter of human nature that only sees financial gain without any concern for environmental or human cost. On balance, capitalism appears more likely to accelerate technology because communism more often follows than changes scientific direction.

The growth of knowledge comes from science and exploration of the unknown, but its use can be destructive as well as constructive.

Some think A.I. will lead the world to greater knowledge and prosperity while others believe it will destroy human life. A sceptic might suggest both views are wrong because A.I. is only a tool for recalling knowledge of the past to help humans make better decisions for the future. The real risk, as it has always been, is human leadership.

Harari believes, like Nietzsche, that God is dead because belief in God is losing its power and significance in the modern world.

Though many still believe in God, it seems more people are viewing God as a myth. The Pew Research Center reports a median of 45% of people across 34 countries still believe in God. However, the variation is wide with Brazil saying 70% believe while in Japan the percentage is only 20%. Harari implies belief in God is in decline.

Harari explains biophysics illustrates that human thought is algorithmic. He argues our thoughts, decisions, and behaviors can be understood to be a result of patterns created in human brains that are pre-determined. There is no “free-will” in Harari’s opinion. This is not to suggest aberrant behavior does not exist, but that human thought and action is determined by our experientially defined brain in the same way a computer is programmed. Experience from birth to adulthood is just part of a mind’s programming.

Harari implies understanding of brain function will change the world as massively as the Agricultural, Industrial, and technological revolutions.

Harari goes on to suggest humans have never been singular beings, but a multitude of beings split into two brains that mix and match their biogenetic and biochemical programming to think and act in pre-determined ways. Experiments have shown that the way the left half of a human brain sees and compels action is different than how the right brain sees and compels action. Each half thinks and acts independently while negotiating a concerted action when both halves are functioning normally. That negotiation between the two brain halves results in an algorithm for action based on the biochemical nature of the brain. The way two halves of the brain interact multiply the person we are or will become.

Imagine the potential of a mind that can recall the history of the world with biochemical programming that has the power to create new thoughts and actions.

Energy

Wysession explains coal and gasoline production costs will continue to rise making them too costly for most consumers.

The Science of Energy (Resources and Power Explained

By: The Great Courses

Narrated By: Michael E. Wysession

Michael E. Wysession (Brown University and Northwestern University PhD graduate in 1991, chair of the National Science Foundation (NSF).

Professor Wysession offers an overview of the world’s energy crises with a detailed history of “The Science of Energy”. It is a daunting series of lectures about the chemical nature and origin of energy with its evolving role in world economies. From a chemical perspective, energy is the capacity to do work or produce change. Wysession identifies the many forms of energy ranging from coal to oil to thermal to biological sources of fossil fuels. He reinforces the belief that global warming is largely the result of growth in carbon dioxide in the atmosphere exacerbated by the continued use of fossil fuels.

Wysession explains energy can be stored, transferred, and transformed by chemical reactions and processes. It is the bonding and breaking of atoms in molecules that create energy. He explains there are exothermic and endothermic reactions with combustion that create energy to move machinery and photosynthesis for plant growth.

To some, it is a surprise to hear of Wysession’s optimism about the future. He argues the world’s effort to sequester carbon dioxide and reduce dependency on fossil fuels will abate global warming, maintain, and sustain human life.

His optimism is based on a clear-eyed and educated understanding of how carbon dioxide increasingly damages the environment while fossil fuel use continues to pollute the air we breathe.

Wysession explains carbon dioxide is a greenhouse gas that traps heat in the Earth’s atmosphere.

That trapped heat is melting the ice caps, raising sea levels, and causing severe weather events like hurricanes, floods, and ironically, droughts. Higher carbon dioxide levels exacerbate respiratory and cardiovascular disease because of increased particulate matter in the air that causes heart attacks and strokes. Rising carbon dioxide levels increase ocean acidification that reduce biodiversity and threaten coral reefs and shellfish. Extreme weather events destroy farm crops and affect the food and water security of millions of people. Wysession notes the world economy suffers because of damaged infrastructure, increased health care costs, and loss of productivity from fossil fuel accidents and health consequences.

Greenhouse gases released by fossil fuels trap heat that causes the earth’s temperatures to rise.

The direct impacts of fossil fuel use and extraction are well known. Fossil fuels create air and water pollution that causes habitat destruction, and ocean acidification. Wysession notes both extraction and use of fossil fuels causes environmental damage from pollution’ accidents and methods of extraction from the earth.

Wysession notes some progress by world leaders in reducing the use of fossil fuels.

Wysession notes advances in renewable energy technology with solar, wind, and battery storage. He comments on the international cooperation in reducing greenhouse gas emissions and public awareness of the consequence of failure to address fossil fuel pollution. There are also economic benefits from the jobs created with solar, wind, and carbon capture manufacture. (One hopes but doubts our new President understands and acts on those job creation opportunities.)

Wysession believes it is important to keep in mind the potential of nuclear energy in the world’s future.

He revies the history of nuclear fission and fusion. As is widely known, our sun provides energy to the world with fusion that feeds photosynthesis which fuels plant growth by converting carbon dioxide and water into glucose and oxygen, both of which are critical needs for life on earth.

Fusion is a process where two nuclei combine to form a heavier nucleus which releases energy. The energy comes from the kinetic interaction of the nuclei. Though science has not successfully achieved the high temperatures of a sun-like process to make fusion a viable source of energy on earth, it has been done on a small scale. It has not achieved a sustained and economically viable form of energy but its potential as a clean energy source is limitless. In the meantime, fission has worked to destroy people and things while showing it can be harnessed to provide energy to the world. As of May 2024, there are 440 nuclear reactors in operation, with the U.S. having the most at 94.

Wysession acknowledges rising population demands more and more energy but he argues the average energy use of people in the United States has fallen to 10 KW per person and believes it will continue to drop in the future.

Wysession’s drop in energy use per person (whatever that means) may be correct, but the reality is that American population increases show energy use has risen in the 21st century to 94 quadrillion Btu. (Whatever a quadrillion Btu means.)

In the late 20th century, our consumption was 75-80 quadrillion Btus annually. American consumption has risen by 14 quadrillion Btu, i.e., a 17.5 percent increase in 23 years. Though the numbers are incomprehensible, energy consumption in America is rising, not falling.

He notes there are over 70 percent more people on earth than when he was born. The rising cost of gasoline will compel more transition to electric automobiles. He believes coal and gasoline use will continue to decrease for both environmental reasons and consumer costs. Wysession explains coal and gasoline production costs will continue to rise making them too costly for most consumers. He believes energy production of wind, solar, hydro, and nuclear power will become more viable and less costly as science advances. From his lectures to our ears, listeners hope he is right.

PROGRESS IN SCIENCE

The point of “The Structure of Science Revolution” is that a paradigm begins science exploration, new paradigms challenge old paradigms, old paradigms persist, new paradigms demonstrate improved knowledge over old paradigms, old paradigms are overturned, and a new paradigm begins further search for knowledge

The Structure of Scientific Revolutions

By: Thomas S. Kuhn

Narrated By: Dennis Holland

Thomas Kuhn (Author, 1922-1996 died at age 73, American historian and philosopher of science at Harvard and the University of California, Berkeley.)

This is a tough ten-hour listen. It does offer an overview of the evolution of science and how new discoveries have changed human understanding of the physical universe in a revolutionary way. Kuhn suggests every revolution in science begins with a paradigm, a model or framework that offers a clearer understanding of the physical universe.

Kuhn suggests every revolution in science begins with a paradigm.

The momentous discoveries of Newton, Einstein, Darwin, and Galileo are a few of the revolutionary leaders that Kuhn offers as examples. Newton developed a paradigm of earth’s laws of motion and universal gravitation that revolutionized understanding of forces and momentum on earth. Einstein developed a paradigm of the universe by introducing theories of special and general relativity that revolutionized our understanding of space, time, and gravity. Darwin developed a paradigm of animal evolution and natural selection that revolutionized biology and life’s diversity. Galileo developed a paradigm of our universe that revolved around the sun that revolutionized our view of the cosmos and humans place in it.

All of these geniuses created new, often more comprehensive, paradigms than predecessors like Aristotle, Ptolemy, and Democritus. New paradigms about air, the planets, and atoms improved predictability of results from new paradigms of thought, and experimentation that became more comprehensive and accurate than thoughts and experiments on older paradigms. Kuhn argues new paradigms foment science revolutions.

Kuhn explains how a new paradigm is challenged because of generally predictable results from older science discoveries.

The argument is made that the older discovery is better because it did have predictable results and the only reason there is an aberration is because of an undiscovered anomaly that will be discovered and explained by further thought, observation, and experimentation. However, as evidence from experiment grows to show older science discoveries are not as comprehensively predictable of results as the new paradigm, the new paradigm replaces the old one and a revolution ensues.

This is an insightful story but one gets bogged down by the number of examples that repeat similar revolutions.

The objections from old paradigm believers, failed old paradigm predictions, and ultimate revolution by new paradigms are repeated too many times.

LEARNING

There are many brain discoveries and therapies to be discovered that will extend the ability of human beings beyond today’s capabilities. Those discoveries are like the discovery of fission. The science of brain plasticity has potential for either programing destruction or liberating the mind.

The Brain That Changes Itself: Personal Triumphs from the Frontiers of Brain Science

By: Norman Doidge, M.D.

Narrated By: Jim Bond

Norman Doidge (Author, Canadian psychiatrist, psychoanalyst, studied literary classics and philosophy at the University of Toronto.)

To an older person, there is a sense of disappointment and optimism from what Norman Doidge writes in “The Brain That Changes Itself”. The disappointment is the feeling of lost opportunity for some because of their ignorance of how the brain works. The optimism is that the past is passed while Doidge explains brain improvement is not completely lost with either age or injury. For older people, improving brain function is more difficult but not impossible. For the injured or medically challenged brain improvement is a dire necessity. For the young, improving brain function is at its best unless there are medical complications.

Doidge explains as one grows older or suffers from brain injury; the brain can be rewired to improve learning or restore bodily function.

Age slows the synaptic process of learning, but the brain is still receptive to synaptic improvement. Older brains simply have to work harder to compel new neuronal synaptic connections. With brain injury or disease, new connections must be made by different parts of the brain to restore the relationship between thought and action. A youthful brain is likely to improve faster than an older brain, but experimental studies show improvement is possible for both. Doidge explores brain plasticity in “The Brain That Changes Itself”.

Doidge explains medical or physical deterioration of brain function can be improved with repetitive effort.

What brain disfunction has in common is the ability to adapt to the circumstances of people’s lives. With the appropriate help of teacher, clinician, and self exercise, people can rewire their brain.

The difficulty is in societies willingness to invest in the professional needs of those who are affected by brain dysfunction. Treatment of the aged requires commitment to repetitive learning and relearning which can be done with personal commitment. It is not the same for those who lose motor control of their body from injury or medical conditions. The requirement Doidge and others have found for medical or physical brain injury is the training and availability of clinicians and physicians to provide the therapeutic treatment that will aid recovery. How many medical clinicians have been trained to aid brain-dysfunction’ patients to re-wire their brains to think, see, hear, or walk? How many patients can afford the treatment?

The potential of rewiring the brain extends to returning old brains to their childlike state of openness with drugs. It is a new frontier that illustrates how human brains are superior to A.I.

“The Brain That Changes Itself” reveals a lot about the science of re-wiring the brain. Re-wiring the brain for older people is possible with minimal assistance but it requires repetitive work. For the brain damaged, the need for neurologists, clinicians and other professionals are essential for treatment success. The difficulty is in balancing need with cost and the public’s ability to pay.

Brain plasticity can either aid or destroy society.

Doidge notes how North Korean children are taught from grade school through high school to see their leader as a god, not a fallible human being. The less formed minds of the young are more easily programed than adults. He shows brain plasticity is a new frontier in medicine that can be abused.

WORRY OR NOT

Artificial intelligence is an amazing tool for understanding the past but its utility for the future is totally dependent on its use by human beings. A.I. may be a tool for planting the seeds of agriculture or operating the tools of industry but it does not think like a human being.

Genesis (Artificial Intelligence, Hope, and the Human Spirit)

By: Henry A. Kissinger, Eric Schmidt, Craig Mundie

Narrated By: Niall Ferguson, Byron Wagner

NOTED BELOW: Henry Kissinger (former Secretary of State who died in 2023), Eric Schmidt (former CEO of Google), and Craig Mundie (a Senior Advisor to the CEO of Microsoft).

“Genesis” is these three authors view of the threat and benefits of artificial intelligence. Though Kissinger is near the end of his life when his contribution is made to the book, his co-authors acknowledge his prescient understanding of the A.I. revolution and what it means to world peace and prosperity.

On the one hand, A.I. threatens civilization; on the other it offers a lifeline that may rescue civilization from global warming, nuclear annihilation, and an uncertain future. To this book reviewer, A.I. is a tool in the hands of human beings that can turn human decisions for the good of humanity or to its opposite.

“Genesis” offers a mixed message.

A.I. gathers all the information in the known world, answers questions, and offers predictions based on human information recorded in the world’s past. It is not thinking but simply recalling the past with clarity beyond human capability. A.I. compiles everything originally noted by human beings and collates that information to offer a basis for future decision. Information comprehensiveness is not an infallible guide to the future. The future is and always will be determined by humans, limited only by human judgement, decision, and action.

Artificial intelligence is considered by some historians as equal to or greater than either the Agricultural or Industrial revolutions.

The danger of A.I. remains in the thinking and decisions of humans that have often been right, but sometimes horribly wrong. One does not have to look far to see our mistakes with war, discrimination, and inequality. In theory, A.I. will improve human decision making but good and bad decisions will always be made by humans, not by machines driven by Artificial Intelligence. A.I.’s threat lies in its use by humans, not by A.I.’s infallible recall and probabilistic analysis of the past. Our worry about A.I. is justified but only because it is a tool of fallible human beings.

Artificial Intelligence is just that, i.e. artificial.

The authors conclude the Genie cannot be put back in the bottle. A.I. is a danger but it is a humanly manageable danger that is a part of human life.

The risk is in who the decision maker is when A.I. correlates historical information with proposed action. The authors infer the risk is in human fallibility, not artificial intelligence.

PATTERN ME

One may conclude from Hawkin’s research that human beings remain the smartest if not the wisest creatures on earth. The concern is whether our intelligence will be used for social and environmental improvement or self-destruction.

On Intelligence

By: Jeff Hawkins, Sandra Blakeslee

Narrated By: Jeff Hawkins, Stefan Rudnicki

Jeff Hawkins (Author, American neuroscientist and engineer)

Jeff Hawkins co-founder of Palm Computing and co-creator of PalmPilot, Treo, and Handspring.

Hawkins and Blakeslee have produced a fascinating book that flatly disagrees with the belief that computers can or will ever think.

Hawkins develops a compelling argument that A.I.’ computers will never be thinking organisms. Artificial Intelligence may mislead humanity but only as a tool of thinking human beings. This is not to say A.I. is not a threat to society but it is “human use” of A.I. that is the threat.

Hawkins explains A. I. in computers is a laborious process of one and zero switches that must be flipped for information to be revealed or action to happen.

In contrast to the mechanics of computers and A.I., human minds use pattern memory for action. Hawkins explains human memory comes from six layers of neuronal activity. Pattern memory provides responses that come from living and experiencing life while A.I. has a multitude of switches to flip for recall of information or a single physical action. In contrast, the human brain instantaneously records images of experience in six layers of neuronal brain tissue. A.I. has to meticulously and precisely flip individual switches to record information for which it must be programmed. A.I. does not think. It only processes information that it is programmed to recall and act upon. If it is not programmed for a specific action, it does not think, let alone act. A.I. acts only in the way it is programmed by the minds of human beings.

MEMORY & INTELLIGENCE

So, what keeps A.I. from being programmed to think in patterns like human beings? Hawkins explains human patterning is a natural process that cannot be duplicated in A.I. because of the multi-layered nature of a brain’s neuronal process. When a human action is taken based on patterning, it requires no programming, only the experience of living. For A.I., patterning responses are not possible because programming is too rigid based on ones and zeros, not imprecise pictures of reality.

What makes Jeff Hawkins so interesting is his broad experience as a computer scientist and neuroscientist. That experience gives credibility to the belief that A.I. is only a tool of humanity. Like any tool, whether it is an atom bomb or a programmed killing machine, human patterning is the determinate of world peace or destruction.

A brilliant example given by Hawkins of the difference between computers and the human brain is like having six business cards in one’s hand. Each card represents a complex amount of information about the person who is part of a business. With six cards, like six layers of neuronal receptors, a singular card represents a multitude of information about six entirely different things. No “one and zero” switches are needed in a brain because each neuronal layer automatically forms a model that represents what each card represents. Adding to that complexity, are an average of 100billion neurons in the human body conducting basic motor functions, complex thoughts, and emotions.

There are an estimated 100 trillion synaptic connections in the human body.

The largest computer in the world may have a quintillion yes and no answers programmed into its memory but that pales in relation to a brains ability to model existence and then think and act in response to the unknown.

This reminds one of the brilliant explanation of Sherlock Holmes’ mind palace by Sir Arther Conan Doyle. Holmes prodigious memory is based on recall of images recorded in rooms of his mind palace.

Hawkins explains computers do not “think” because human thought is based on modeling their experience of life in the world. A six layered system of image modeling is beyond foreseeable capabilities of computers. This is not to suggest A.I. is not a danger to the world but that it remains in the hands and minds of human beings.

What remains troubling about Hawkin’s view of how the brain works is the human brains tendency to add what is not there in their models of the world.

The many examples of eye-witness accounts of crime that have convicted innocent people is a weakness because people use models of experience to remember events. Human minds’ patterning of reality can manufacture inaccurate models of truth because we want our personal understanding to make sense which is not necessarily truth.

The complexity of the six layers of neuronal receptors is explained by Hawkins to send signals to different parts of the human body when experience’ models are formed.

That is why in some cases we have a fight or flight response to what we see, hear, or feel. It also explains why there are differences in recall for some whose neuronal layers operate better than others. It is like the difference between a Sherlock Holmes and a Dr. Watson in Doyle’s fiction. It is also the difference between the limited knowledge of this reviewer and Hawkins’ scientific insight. What one hopes science comes up with is a way to equalize the function of our neuronal layers to make us smarter, and hopefully, wiser.

How the Internet Happened (From Netscape to the iPhone)

By: Brian McCullough

Narrated By: Timothy Pabon

Brian McCullough (Author, CEO of Resume Writers.com, entrepreneur.)

A book about the beginning of the internet is such old news, one is inclined to put this book aside. The internet was born in the 1960s and only became recognizable in the 1980s. However, even in 2024, it is interesting to hear about early users who became rich just by organizing information on an easily accessible and free media platform.

Like this blog, it is rewarding to write something that others are interested in reading.

The exercise of book reviews is a reward to one’s education and an ego boost for a writer from an audiences’ clicks. Brian McCullough tells the story of the founders of YAHOO, Jerry Yang and David Filo who were in college and became fascinated by the World Wide Web because of information it offered with clicks on a computer board. This was in the 1990s. Though there were many websites to choose from, they were disorganized and difficult to find if you were looking for specific information. Yang and Filo began organizing the websites by their offered information. YAHOO’S founders were looking for information of interest to them, and presumed others would like to know how they could use a keyboard to find information they might need or want.

Jerry Yang and David Filo were fascinated by what could be found on the internet.

They spent hours, days, weeks, months that grew into years organizing website addresses so others could find what was interesting to them. In these early years, making money was not their primary objective. They did not use their site to advertise products for income. They felt clicks were their reward and that clicks would be lost if advertisers were allowed to use their site. They chose to have users pay a fee to become members of their site. Their use and organization of the internet became an obsession for them and followers steadily increased. Their click numbers and users rose into the millions and advertisers were again knocking at their door. They resisted until they realized their idea could be worth something more than their interest in learning, gathering, and organizing knowledge. They relented, allowed advertising, and the clicks to their site kept on rising. YAHOO went public. The rest is history.

McCulloch goes on to describe the rise and fall of companies that capitalize on the internet.

The companies ranged from behemoth companies like Amazon, Microsoft, Google, Apple, and Ebay that rocketed to the stratosphere while Priceline.com, Netscape, Pets.com, Webvan and others plunged into the abyss. This is not to say today’s behemoths will continue to dominate the market or that some new company will replace their success with even greater appeal. A.I., like the internet, may be a killer discovery that makes or breaks today’s behemoths into tomorrow’s also-rans or hangers-on.

McCulloch’s history is interesting because it explains how winners understood the future better than losers understood the present.

It’s fascinating to find Apple’s Jobs resisted creation of the iPhone but employees worked secretly to refine the idea and Jobs eventually agreed. McCulloch also reveals the monopolistic nature of today’s winners and the threat they present to the future. Killer ideas of today’s tech companies capitalize on the internet’s information ubiquity, and how it can be organized to offer product to the world at a competitive price.

A.I. is a new idea that organizes information on its own with consequences to the public that are yet to be realized. Just as McCulloch’s history shows how the internet changed yesterday, it seems A.I. will change the future.

“Real Americans” A Novel

By: Rachel Khong

Narrated By: Louisa Zhu, Cric Yang, Eunice Wong

Rachel Khong (American writer and editor.)

(Ms. Khong’s book is an entertaining listen but a little too long except for listeners who are most interested in the story. Others are interested in its societal meaning and often discount its entertainment value.)

The main characters in Khong’s novel are Lily Chen, Matthew, Nick Chen, and May. In one sense, the author’s story is about the randomness of life. We are born from fertilization of a male sperm with a female egg. In our world, the randomness of being born is based on chance encounters of violence or seduction. (The reference to violence and seduction is not meant to suggest the nuance of relationship can be ignored, e.g. love comes from the act of seduction, not from violence.) In the 21st century, violence and seduction remain but in today’s science, state and institutional influence bear down on human procreation. The science and possible future of genetics is Khong’s theme in “Real Americans”.

“Real Americans” is about a young college graduate making her way in New York city, a capitol of opportunity in America.

As a poor young graduate, New York city is a ticketed opportunity for American success and failure. Khong’s story is particularly interesting because the main character, Lily Chen, is born American to well-educated parents who emigrated from China. She does not speak Chinese. She is living the life of a young, intelligent American trying to support herself by whatever job she can find in New York City.

Lily’s mother and father are geneticists.

Like the trials and rewards of Cinderella, the trials of Lily’s life are transformed by the wealth of a prince. What makes “Real Americans” more than a fairytale is its theme that life’s beginnings are a matter of violence or seduction, including state and institutional complicity. (“State and institutional complicity” refers to acts of government and business that discriminate based on prejudice or narrow emphasis on income rather than ethics.)

Lily seems to have luckily met Matthew; an immensely wealthy heir to an American medical conglomerate founded by his family. They marry after an on again, off again relationship.

After their marriage, Lily has two pregnancies that do not come to term and chooses to have invitro insemination to have a successful pregnancy with the birth of a son they name Nicco. Matthew and Lily go to China on a business trip where Lily chooses to visit the college where her mother became a geneticist. She meets a professor who knew her mother and is told a story that initially puzzles her about what her mother was like when she was young. She finds her mother, as a student geneticist, was a risk taker and magical thinker.

The next one learns is that Lily divorces her husband and moves from New York to Tacoma Washington, an island between Seattle and its capital to raise her son by herself.

Lily’s mother had met Matthew’s family before Matthew began dating Lily. She knew Matthew’s father who began a hugely successful medical company that researched genetics. (The significance of her mother’s knowledge of the genetic research of Matthew’s family is at the crux of Lily’s feeling of betrayal.) The theme of the author’s story begins to take a turn. Lily leaves Matthew. (She leaves because of the bias of Matthew’s family in using Lily as a surrogate for pregnancy without disclosing their personal interest.)

As her son grows to manhood, she refuses to tell him the name of his father, where he lives, or the history and wealth of the family in which he was born. The remainder of Khong’s book is the story of the circumstances surrounding the birth of her son, how he learns of his father, and what led to her divorce from Matthew.

“Real Americans” is a theoretical examination of genetics and a future that is still being written.

Khong is writing about the pandora box of genetics which opens the world to designer babies. She seems to conclude, regardless of birth circumstance, care and nurture make people “Real…”. Science will lead or lose the “Real…” world of human beings. (Understanding the science of genetics and the potential for manipulation of human life is a god-like power with all the ramifications of genetic inheritance that can aid or destroy human life.)

“How Medicine Works and When It Doesn’t” Leaning Who to Trust to Get and Stay Healthy

By: F. Perry Wilson MD

Narrated By: Shawn K. Jain, F. Perry Wilson

F. Perry Wilson MD (Author, Harvard graduate with honors in biochemistry, attended medical school at Columbia College of Physicians and Surgeons. He is a practicing nephrologist at Yale New Haven Hospital.)

Doctor F. Perry Wilson is a physician with a biochemistry degree from Harvard, and a medical degree from Columbia College of Physicians and Surgeons. Wilson works at Yale New Haven Hospital where he specializes in kidney issues. Wilson’s book is a problematic view of doctor/patient relationship and what a patient can or should believe about a physicians’ medical diagnosis and treatment. A problematic view is not Dr. Wilson’s intent, but it is a conclusion a reader/listener may arrive at as he/she completes “How Medicine Works and When It Doesn’t”.

Dr. Wilson argues any advice from medical professionals may be listened to with skepticism but not disdain.

In general, that argument seems logical and fairly balanced. Wilson infers skepticism extends to trained medical professionals and the medical industry in general. The reason a lay person may accept that conclusion is based on personal experience and rationality.

As one who has been diagnosed with heart trouble from blocked arteries and medical treatment for an alleged heart attack, the last ten years have been an educational journey.

The first cardiologist who reviewed details of a physical weakness felt while working, suggested the weakness may have been caused by a mild heart attack. After a heart scan, the cardiologist found an artery serving the heart had a blockage. The doctor recommended a stent be inserted to clear the blockage. After surgery, the cardiologist noted the stent could not get through the blockage. Changing cardiologists seemed a prudent action considering the doctor’s failure.

A new cardiologist recommended regular check-ups, stress tests, and medicine to address the cause of the blockage.

Ten years have passed and there have been no further incidents, but relocation required finding a third cardiologist who reviewed medications, conducted further tests. The new cardiologist recommended continued medical treatment largely based on statin prescriptions and further tests. Here is where Dr. Wilson’s book becomes problematic to a patient seeking medical advice from trained medical specialists.

Thomas Hager is a microbiologist and immunologist.

As noted by Thomas Hager in “Ten Drugs”, the relationship between statins and blocked arteries as a cause of heart attacks is somewhat unclear. The unclearness is not that taking stains reduce cholesterol but that statins have side effects. Science-based tests show statins do reduce cholesterol but inhibit memory, reduce cognition, and may cause liver and kidney damage. To add to negative side effects, there is medicine producing industry’ bias that promote statins because they are big revenue producers.

What Doctor Wilson’s book reminds one of is the mid twentieth century game show “Who Do You Trust”. Wilson infers truth is only science-based probability, not certainty.

What both doctor and patient know is based on experience and education, not certainty. For both doctor and patient, it comes down to “Who Do You Trust”.

Wilson’s book is an important example of why patients should use their intuition to trust or change doctors when their health is at risk.

Doctors have spent the greater part of their lives understanding human medical problems and the effect of drugs in treating patients. Patients are unlikely to have had the same level of training or understanding about their own health or the health of the general population. What a patient is left with is the principle of trust. If one trusts the doctor who is prescribing and/or treating one for their illness, the probability of good outcome is logically better.

Doctor Wilson acknowledges profit motive for pharmaceutical companies drives their relationship with the medical profession and the public.

He offers concrete examples of mistakes that have been made by the pharmaceutical companies like the Thalidomide prescriptions that harmed unborn children. Of course, mistakes get made in every discipline of life. The other side of mistakes are the incredible success of vaccines for polio, smallpox, and our world’s most recent crises, Covid 19.

The conclusion one draws from Wilson’s book is trust is the most important characteristic of a patient’s relationship with a physician.

This is not meant to suggest one should shop for a doctor that tells one what they want to hear but to depend on the education and experience of a person who knows more about medicine and its effects than you.
