Essential Physics (A Scientist’s Guide to Life’s Biggest Questions)

By: Sabine Hossenfelder

Narrated by: Gina Daniels

Sabine Hossenfelder (Author, German theoretical physicist, science communicator.)

Sabine Hossenfelder creates unease in listeners who struggle with understanding a world determined by the science of physics. Her first chapter is about the mystery of time. Time is an illusion created by one’s mind. Your time is not my time because our perspectives are influenced by how fast we are moving. If we are in the same room, or one of us is on a train and the other is at the station, the difference is so infinitesimally small, times’ relativity is not comprehended. However, in spacetime with the effect of gravity on radio signals and rocket guidance, time’s relativity becomes navigationally critical.

Hossenfelder notes Einstein explains time is relative and not a constant force of nature because time and space are linked in a way that infers “now” has no meaning.

One can understand the words just written but remain confused about what is called spacetime and its meaning for the past, present, and future. Hossenfelder notes the importance of this physics truth in explaining how travel in space at high velocities cannot be planned for arrivals at specific locations without understanding time’s relativity. Here is where Hossenfelder excels as a science writer. One may not understand the physics of time, but its practical application in space flight and science experiment proves its truth.

One may not understand the physics of time, but its practical application in space flight and science experiment proves its truth.

Hossenfelder, when asking questions of scientists, often asks if they believe in God. Hossenfelder notes most of the scientists she interviews are agnostic but wants to better understand where a scientist’s point of view differs from her own. The inference one draws from Hossenfelder’s question is that God may or may not exist. Her agnosticism implies today’s science neither proves nor disproves His/Her or Its existence.

Hossenfelder’s point is there is no way for science to test or measure the existence of God.

There are a number of interesting thoughts expressed in “Essential Physics”. Hossenfelder believes free will is limited, if not nonexistent, because of the laws of physics. The puzzle of that belief is that present understanding of quantum mechanics is that physics outcomes are probabilistic, not pre-determined actions and their consequences. One may believe there is an undiscovered law of physics that explains “everything about everything” as argued by Einstein. If that undiscovered law of physics is found, then life may arguably be a matter of causes and consequences. On the other hand, what about the person who chooses to do something contrary to what their conscious mind tells them to do? This is a circular argument. The circular argument is that a contrary decision may be a part of a person’s nature which infers their decision remains pre-determined. It is difficult to accept the belief that our lives are predetermined even if Einstein is right and there is an undiscovered physics law that makes quantum physics predictable.

The details of evolution show random modifications of species have determined the makeup of life on Earth.

Hossenfelder discounts belief in a universe made for humans by a superior being. As she notes, evolution suggests otherwise. “The Origin of Species” postulated by Darwin has been supported by science since its publication in 1859.

The science community has tested chemical interactions of the early chemical elements of earth to show prokaryotes and eukaryotes of cellular life can be created from chance chemical and heat interactions.

Hossenfelder raises the question of whether the cosmos has consciousness. She speculates on the origin of the universe as a creation of a superior being or the evolution of a universe from something like the “Big Bang”. Her opinion leans toward the “Big Bang” and evolutionary physics by noting scientific experiments that demonstrate how nature, rather than God, created the Universe.

In writing about consciousness, the author notes the similarity between interstellar atmospheric strings that resemble neuronal connections of the human brain.

“Essential Physics” may help some get closer to understanding the current state of science’s explanation of life, but one may choose to be skeptical because sciences’ pursuit of understanding life remains a work-in-progress. Physics study to date offers no answer to the meaning or destination of life. The truth remains in an “uncanny valley”, a psychological concept of human unease, most recently compounded by genetics discoveries , computer animations, and A.I. influence on life.

Windfall (How the New Energy Abundance Upends Global Politics and Strengthens American Power.)

By: Meghan L. O’Sullivan

Narrated by: Eliza Foss

Meghan L. O’Sullivan (Author, Harvard professor, Former deputy national security adviser on Iraq and Afghanistan, worked in the George Bush administration.)

Meghan O’Sullivan offers an intelligent but flawed view of today’s world. It is true that energy is critical for economic growth and improved human life. It is also true that energy need and development cause international conflicts in the post-industrial world. O’Sullivan does a masterful job explaining the role of energy, noting its cost while explaining fossil fuels are at a turning point in history.

**Fossil fuel prices fluctuated dramatically in the 20th century but O’Sullivan suggests the trend in the 21st century, despite the rise between 2000 and 2008, will trend downward for three reasons.**

One is the recognition of energy’s environmental consequence and conservationists’ political response; two, energy’s extraction is becoming less costly for most fossil fuels. And three, technological advancement offers alternative sources of energy.

What O’Sullivan correctly notes is that energy will remain a driving force behind international relations.

However, her argument is flawed by suggesting governmental restrictions on discovery and growth of fossil fuels should be weakened. Even in the few years since publication of O’Sullivan’s book, the science of fossil fuel pollution is showing accelerating global warming with potential for a “no-return” human’ consequence. Global warming seems self-evident. That evidence does not change O’Sullivan’s insight to the outsize role energy plays in the real-politic world of today, yesterday, and tomorrow.

O’Sullivan loses a bet with a colleague that Russia would challenge world peace within five years of 2013. She was right, but it took a couple years longer for Russia’s re-invasion of Ukraine.

O’Sullivan correctly foretold Putin’s kleptocratic government’s intent to re-establish Russia’s place in the world by using its fossil fuel abundance to lure Europe and Asia with their need for energy. Putin’s drive to offer oil and/or gas pipelines to Germany, China, and Turkiye are meant to assuage their opposition to Ukraine’s invasion. Though China is somewhat supportive of Putin, it has little to do with its energy need but more to do with China’s opposition to U.S. involvement in their sphere of influence. In response to the Ukraine invasion, Germany found alternative sources for Putin’s pipelined energy with imported LNG (liquified natural gas). To some extent, Putin’s energy ploy worked. China, India, and Turkiye continue to buy oil from Russia despite its invasion of Ukraine. Their national interests outweigh their concern about Russia’s invasion, just as Putin undoubtedly calculated.

Energy’s role in the modern world is well documented by O’Sullivan. She notes the history and future of energy and how it will continue to roil international relations.

The cost of energy influences world leaders to exploit the environment despite its harm to society.

Exxon Valdez Oil Spill.

Coal continues to be burned for energy around the world because it is the least expensive.

Malaysia coal fire plant.

Technological innovation is decreasing natural gas costs which, though less environmental damaging than oil or coal, is becoming more widely used. Natural gas remains a pollutant. It is estimated to be 50-60 percent less polluting than coal and 20-30 percent less polluting than oil. (A caveat to the less pollution from natural gas is that it is being used in newer and more efficient energy producing facilities.) This argument does not change O’Sullivan’s flawed argument that restrictions should be removed, weakened, or moderated for further fossil fuel technological development and extraction.

Weather around the world, forest fires, and northern arctic warming are dramatic 21st century proof of continuing global warming. Science and nature tells us the world is warming. That warming is, at the least, greater because of fossil fuel use.

O’Sullivan remains correct in noting how energy is key to peace in the world. The vast natural gas find by Israel, called the Leviathan Reservoir, makes Israel’s influence in the Middle East much greater. Israelis use their natural gas’ find to improve their relationship with Middle East powers. On the other hand, it seems to give license to Israel to repress dislocated Palestinians as irreconcilable enemies.

Energy is both a weapon and tool of peace.

Where O’Sullivan’s book is less convincing is in its inference that the energy industry should be given free rein to continue developing fossil fuels. Even if energy is critical to the sovereign right of every country in the world, degradation of today’s environment makes fools of us all.

The Code Breaker

By: Walter Isaacson

Narrated by: Kathe Mazur, Walter Isaacson

Walter Isaacson (American author, journalist, and professor.)

Walter Isaacson is an interesting and thorough historian as shown in his biographies of Steve Jobs and Leonardo DaVinci. “The Code Breaker” is a history of the human genetic code’s discovery and its societal importance. The stories of Francis Crick, and James Watson are fairly well known because of their discovery of the structure of DNA. They received the Nobel Prize for their discovery in 1962. Less well known are Rosalind Franklin, and Maurice Wilkins.

There are three avenues of knowledge in the book’s title “The Code Breaker”. One is the brief bios of the human genetic code breakers, two, the monumental risk in genetic code’s discovery and three, the potential reward of its discovery.

Maurice Wilkins (1916-2004)

In the late ’40s and early ’50s, as a biophysicist, Maurice Wilkins did diffraction studies of DNA.

Isaacson suggests Wilkins’ studies aided Crick’s and Watson’s discovery of DNA’s structure in 1953. However, Crick and Watson were at a standstill and may never have discovered the structure of DNA if Rosalind Franklin had not introduced X-ray crystallography to their search. Isaacson implies Franklin would have received the Nobel Prize for DNA’s structure but she died at age 37 in 1958. Isaacson notes the Nobel is not given posthumously. (That is not quite true because the Nobel Prize had been awarded posthumously, twice, i.e., once for literature and once for physiology. One wonders if inequality may not have had something to do with the Nobel decision. Isaacson notes Ms. Franklin was somewhat prickly in her relationship with others, not that it would be a reason for Franklin’s lack of Nobel recognition.)

Beyond the syllabus: The discovery of the double helix. Erwin Chargaff (1951): Rule of Base pairing. Rosalind Franklin & Maurice Wilkins (1953): X-ray diffraction pattern of DNA. James Watson & Francis Crick (1953): Molecular structure of DNA.

After discovery of the structure of DNA, the next great advance in science is made by a Spanish microbiologist, Francisco Mojica. Mojica discovers what becomes known as CRISPR in 1993. CRISPR is an acronym for “clustered regularly interspaced short palindromic repeats”. It is the arrangement of the genetic code letters in the structure of DNA that can be read forward and backward. It is a written code for the description of a single gene.

Isaacson introduces Jennifer Doudna and Emmanuelle Charpentier to his biographic history of DNA. They are co-discoverers of what becomes known as CRISPR-Cas9. This is a gene editing tool discovered by Doudna’s team of scientists that could find anomalies in a gene’s genetic code and, with the aid of a virus, implant a revised code or modify a gene that causes harm to its host. That discovery opens a door to human control of genetic code. In principle, CRISPR-Cas9 takes the place of nature’s random selection of who or what a living thing becomes. It is a tool that can change the course of life for all living things; more particularly the lives of human beings who suffer from diagnosed diseases or illnesses.

Doudna and her scientific team’s work is with prokaryotic cells rather than eukaryotic cells.

Eukaryotic cells have a nucleus with genetic material while prokaryotic cells have no nucleus with free floating genetic material. Humans have many prokaryotes but they are not enclosed within a nucleus. That leaves a door open to other scientists to claim precedent over Doudna’s pioneering work on the genetic code.

Feng Zhang (Chinese American biochemist.)

Zhang opens the door to eukaryotic cell modification with CRISPR-Cas9 which suggests he becomes the discover of human genetic code breaking before Doudna.

Doudna takes Zhang to court over a patent issue on CRISPR-Cas9 and eventually wins the patent right for genetic code breaking and its medical potential. There are a number of other scientists involved in Isaacson’s book but Doudna, Charpentier, and Zhang seem most consequential for understanding the significance of genetic code breaking.

CRISPR-Cas 9’s discovery and use gives science a tool for human’ control of evolution rather than Darwinian natural selection’s control .

The remainder of Isaacson’s history is an exploration of the good and bad potential of that discovery for the human race. Without doubt, the world’s recovery from Covid19 is due to CRISPR Cas9’s use in finding a vaccine for the pandemic. On the other hand, Cas9 opens the door to indiscriminate gene modification.

This brings up the story of Jiankui He who modified the genetic code of one of the twins of a Chinese family whose husband had AIDs.

Jiankui’s medical intervention violated Chinese law and ethics rules set by the Academic Committee of the Department of Biology. At the same time, it was found that Jiankui botched the use of the CRISPR Cas9 tool. He was sentenced to three years in prison and the equivalent of a $430,000 fine.

James Watson is now in his 90s.

The last chapters of Isaacson’s book address the controversial comments of James Watson about race and intelligence and his fall from grace despite being co-discoverer of the structure of DNA.

At a visit by Isaacson and Doudna to Watson’s home when he is 90, one cannot forget nor forgive Watson’s blind spot about race but understand his unshakable belief in the value human modification of genes to cure disease and his admittedly controversial ideas of enhancing human looks and intelligence.

Is behavioral hope a genetically identifiable characteristic by CRISPR-Cas9? Is it possible to modify human genes to create a more empathetic world? Or is gene manipulation a Mary Shelley nightmare with societies’ death like Dr. Frankenstein’s monster that dies from sorrow and guilt from the death of its creator?

The final significant note of “The Code Breaker” is Doudna’s and Emmanuelle Charpentier’s receipt of Nobel Prizes in 2020 for their discovery of CRISPR-Cas 9. By the end of “The Code Breaker”, a listener understands how the human race may become happy, healthy, or dead with control of the genetic code. Breaking the genetic code becomes a matter of human volition rather than nature’s decree. In whose hands will humans choose to be?

QUANTUM

Helgoland (Making Sense of the Quantum Revolution)

By: Carlo Rovelli, Erica Segre-translator, Simon Carnell

Narrated by: David Rintoul

Carlos Rovelli (Italian author, theoretical physicist.)

Carlo Rovelli’s book title, “Helgoland”, refers to a small island in the North Sea, off the coast of Germany. Werner Heisenberg, a pioneer in quantum mechanics theory, visits the island to think about the mystery of matter and energy and how it works at a subatomic level.

Werner Heisenberg (German theoretical physicist, pioneer of the theory of quantum mechanics. Born 1901, died 1976 at the age of 74.)

Rovelli explains this 20-year-old wunderkind had been given an assignment by Niel’s Bohr to determine how a quantum works in a subatomic environment. (A quantum is the minimum amount of a physical property’s interaction with the substance of the world.) The author suggests Heisenberg chooses Helgoland to think about his complicated assignment because he suffers from allergies which would not be aggravated by the austere island’s environment.

Rovelli argues that Heisenberg believes the known postulates of physics, rather than a new theory, held the key to the quantum world.

Using the tools of known physics, Heisenberg observed and recorded the actions of quantum particles. What he found was their actions could be measured mathematically with the addition of a matrix of numbers to finite calculations of known physics phenomena. The matrix introduced the principle of probability rather than certainty to quantum action at a sub-atomic level. This revelation overturned the certainty principles of cause and effect presumed by the Einstein’ physics community.

At a subatomic level, Heisenberg’s observation and number matrix postulate probability rather than certainty as a fundamental law guiding the principle of existence.

Rovelli goes on to explain this fundamental change in the understanding of physics is elemental but not substantively different for life as we know it. The author argues life remains relational at all scales of existence, just as it did before quantum mechanics became physics guiding principle. However, quantum physics remains mysterious and has led to new ideas like the many worlds’ hypothesis, the Copenhagen interpretation, and the Broglie-Bohm theory.

What Rovelli concludes in “Helgoland” is that what humans see, hear, feel, and think are based on relational understanding of the world.

Rovelli argues the world is a material place, but its substantive reality is based on life’s perceiver. This is a comforting and terrifying argument. It explains why humans can be so right about what is perceptually true and advantageous but also wrong and disastrous because of misleading perceptions.

HUMANITY’S TRIAL

The Earth Transformed: An Untold History

By: Peter Frankopan

Narrated by: Peter Frankopan

Peter Frankopan, (Author, Professor of Global History at Oxford University, Director of the Oxford Centre for Byzantine Research.)

Peter Frankopan journeys from pre-history to the present to offer perspective on the earth’s global warming crisis. He reviews what is either speculated or known of disastrous world events. Frankopan recalls histories of major volcanic eruptions, earthquakes, tsunamis, droughts, famines, pandemics, and epidemics that have changed the course of history.

In the beginning, one thinks Frankopan is setting up a rationalization to argue global warming is just another world changing crisis that will be managed by humanity.

However, Frankopan is explaining the history of world crises and how humanity dealt with its eternal recurrence. In broad outline, he suggests world crises are dealt with in two ways, i.e., one, with religion or mysticism, and/or two, with adaptation. In every historical crisis, leadership is the presumed key to survival.

Frankopan explains the common denominator for crises that change the world is death.

Just as America and the world recovers from Covid-19, millions have died. We who remain carry on.

Whether a catastrophic event is geological, climatological, or pathogenic, life is a victim. Before history is written, Frankopan offers explanations of what happened to life based on fossilized remains. Causes for death are either geological (like earthquakes), climatological (like volcanic dust that blocks the sun), pathogenic (like the plague or a virus), or manmade (like the nuclear bomb). When written history begins, Frankopan’s evidence of world crises is more precisely explained. (From an objective perspective of any historian’s story, any history of the past is trapped in His/Her’s interpretation of other’s reported facts.)

Frankopan argues life on earth has come and gone through centuries of crises.

The evolution of human beings shows they have managed to ameliorate past crises by meeting them head-on. Humans have overcome crises by adapting to change, whether manmade or environmental. If the past is prologue to life’s survival, global warming’s threat will be met and ameliorated by human response. Just as all crises in world history have ended lives, the same is true of global warming. That does not necessarily mean all human life ends. Frankopan’s history infers life will be changed by global warming but leaves unanswered whether human life will end.

Jumping ahead in Frankopan’s scholarly review of history, the age of Sputnik emphasized the growing importance of science in the ecology of the world.

The Russian Launch of Sputnik in 1957.

Ironically, Russia’s giant step ahead of America in the space race awakened the world to the importance of science. Frankopan notes the hubris of humanity taking center stage with Khrushchev’s comments about humankind’s need and ability to control nature. To Frankopan, control of nature is a turning point in the hubris of humankind. He notes the U.S.S.R. experiments with weather control as a way to improve agricultural productivity. Frankopan suggests the real objective is to realize the potential of weather control as a weapon of war and goes on to explain how America capitalizes on that idea in the Vietnam war.

The irony and hubris of humanity in believing it can control the weather is evident in the despoiling of earth by human ignorance and action.

The profligate use of carbon-based energy for industrial growth far outstrips any science driven effort by humanity to control the weather. World ecology has proven too complex for constructive control by human beings. It is as though the world is being turned back to religion and myth to explain the phenomenon of world existence.

The last two chapters address overwhelming evidence for causes and consequences of late 20th and early 21st century world’ environmental damage.

From deforestation in the Amazon, to automobile increase in China, to waterway dams and aquifer depletion, a listener/reader’s fear and depression are kindled.

Harvard educated politicians like Ted Cruz and poorly educated Presidents like Donald Trump insist global warming is a hoax. As political power representatives of the wealthiest country in the world, one cannot but be appalled by climate change deniers.

The world’s future is based on an unknown solution to global warming.

Some suggest A.I. is key to solving global warming. Frankopan’s history suggests it is human beings that gave humanity the ability to overcome past crises. A.I. is one of humanities tools. It seems fair to suggest today’s crises will be another difficult chapter in the history of humanity. Judging by Frankopan’s history of human adaptation, global warming may not be humanities last chapter. However, Frankopan warns listerner/readers against the hubristic belief that nature can be controlled by humankind.

Stephen Hawking suggested humanity will not survive another 1,000 years on Earth and that human survival depends on colonization elsewhere in the Solar System. Frankopan seems to infer, humanity does not have that much time.

Frankopan wryly observes global warming is a crisis, but that human life is more likely to end from some other cataclysmic natural event like that which killed the dinosaurs (a meteor strike), a massive underwater volcanic eruption, or nuclear war before global warming kills us all.

One hopes histories past lessons inform a future that includes a place for the youth of this, the next, and future generations. World change brought on by crises have been overcome in the past through human adaptation. It seems reasonable to presume, despite the ignorance of some national leaders, that humanity will survive today’s global warming crisis.

FEELING & KNOWING

Feeling & Knowing

By: Antonio Damasio

Narrated by: Julian Morris

Antonio Damasio (Author, Portuguese American neurologist, Professor at the University of Souther California.)

Antonio Damasio refines the definition of consciousness in “Feeling & Knowing”. Damasio offers a more science based, experiment driven, view of consciousness than Helen Thompson’s “Unthinkable…” “Feeling and Knowing” is a shorter version of Anil Seth’s book “Being You” that also addresses consciousness.

Both Damasio and Seth argue consciousness comes from feelings.

Thompson offers a less science driven view of consciousness based on patient interviews that reinforce Damasio’s and Seth’s views. There seems a slight difference between Damasio’s and Seth’s view of consciousness in the belief that emotions or feelings are the source of thought and knowledge origination. Seth argues emotions originate in the organs of the body and inform the brain. Damasio is more circumspect and seems to argue emotions come from the body and brain in a synchronous way.

Damasio emphasizes patterning of what one sees as a complex neural response that offers a composite view of the world.

However, Damasio’s and Seth’s beliefs about consciousness seem entirely compatible. That composite view changes with additional input which suggests consciousness is not a precise representation of reality.

To Damasio, one’s view and understanding of the world comes from feelings processed and imprinted on, and by, the brain. This is not to say that the brain is only a processor but that it works synchronously with the organs of the body.

Damasio emphasizes feelings as the primary knowledge source of the human experience. Damasio’s theory suggests artificial intelligence will always be artificial because it relies on the logic of ones and zeros rather than the dynamic process of emotion interface with brain processing.

If Damasio is correct, for A.I. to become a learning machine, emotion must be a part of its programming.

If emotion can be and is programmed into a machine, there seems a probability that humanity will become servant rather than master of the universe.

BEAST MACHINE

Being You (A New Science of Consciousness)

By: Anil Seth

Narrated by: Anil Seth

Anil Seth (British professor of Cognitive and Computational Neuroscience at the University of Sussex.)

Anil Seth’s “Being You” is a difficult book to understand, in part because of its subject, but also because it requires a better educated reviewer. Consciousness is defined as an awareness of yourself and the world, a state of being awake and aware of one’s surroundings that emerges from one’s brain. Seth explains neuronal activity of the brain correlates with what “Being You” is you. Seth argues that without neuronal activity, there is no you.

Seth suggests the conscious self operates with a Bayesian view of the world.

Bayes’ theory is that decision making is based on rules used to predict one’s decisions. The example Seth gives is a person living in the desert who sees droplets of water on his lawn and presumes it either rained, or his sprinkler was left on when it should have been turned off. He looks outside and sees his neighbor’s lawn is wet and, with that added information, decides it must have rained. Then he notes his window is dirty and maybe he is not seeing water on his neighbor’s lawn. This reduces the possibility that it rained but not enough to change his mind about it having rained last night. The point is that one continually changes their state of understanding (their consciousness) based on added information.

The difficulty of a Bayesian view of consciousness is that human decisions are a function of human perception of data that is never 100 percent complete.

There are three fundamental weaknesses with a Bayesian view of the world as the prime mover of consciousness. One, humans do not always see clearly. Two, all that is seen is never all that there is to be seen. And three, human minds tend to pattern what they see to conform to their personal bias. The third is the most troubling weakness because, like in police line-ups used for eyewitnesses to identify perps when a crime is committed, mistakes are made. Eyewitnesses are no guarantee for identification of a criminal’s crime. None of this is to suggest Seth is wrong about what consciousness is but it shows consciousness is eminently fallible and only probabilistic.

Seth’s theory of consciousness reinforces the public danger of social websites that influence the public, particularly young adolescents trying to find their way in life. Their search for social acceptance leads them to internet sites that may lead or mislead their lives.

Another fascinating argument by Seth is that the mind is not the source of emotion. He suggests the mind is informed by the organs of the body. The heart begins to race, and adrenalin is released as somatic markers that send signals to an area of the brain that makes fight or flight decisions. Emotions do not originate in the brain. The brain responds to the cumulative effect of the body’s physical and chemical signals.

Seth notes various studies of human decision making that are based on external stimuli with a belief that the primary purpose of consciousness is to survive. Two methods of consciousness measurement are IIT (Integrated Information Theory) and PHI, a number meant to measure quality interconnections between bits of information of a given entity. The resulting number — the Phi score — corresponds directly to a measurement of an entities level of consciousness. A reader/listener should not be discouraged by this technical digression. Much remains in Seth’s book that is more comprehensible and interesting.

Seth explores some of the tests used for consciousness. The mirror test is one in which a living thing is shown itself in a mirror to see if it recognizes the image of itself.

Monkeys show some signs of recognition (dogs do not) which suggests a greater level of consciousness among primates. He notes the evolution of human perception of the world through the eyes of artists like Monet, Mach, and Picasso who see nature’s colors and planes of the face or body in the material world. One thinks of Monch’s insightful “Scream” that reminds some of life’s terror. He shows how a stationary drawing seems to have movement because of a trick of consciousness.

**Seth shows how an inanimate rubber hand can be made to feel like a part of the human anatomy by stroking one’s real hand at the same time the experimenter strokes a rubber hand.**

Seth expands that principle to show how consciousness can create a full body illusion like that of a Star Trek transporter that sends their body to another planet. A whole host of social problems can be created by image teleportation. Being able to create a perfect duplicate of one person that is televising false information might start a rebellion or start a war.

Seth argues humans have free will and that the brain’s pre-cognition for action is not because of pre-determination of life but a delay inherent in consciousness which is gathering information before acting, just like the sprinkler story alluded to earlier. As noted earlier, to Seth, consciousness is a Bayesian process, not a predetermination of action.

The end of “Being You” addresses Ray Kurzweil’s “singularity”, “a future period during which the pace of technological change will be so rapid, its impact so deep, that human life will be irreversibly transformed. Seth expresses concern and an element of optimism. The evolution of the beast machine bodes a possible end, an adaptation, or an evolutionary change of humanity.

Seth touches on research being done on cerebral organoids, artificially grown miniature organs resembling the brain.

Presently they are being used to model the development of brain cancer to aid in its cure but how far is this from the next step in machine learning, supplemented by the implantation of cerebral organoids?

The beast machine is consciousness.

Genetics discoveries and research hold the potential for creation, manipulation, and destruction of human life. Artificial Intelligence is on the precipice of a marriage between all information in the world and sentient existence of beast machines. The beast machine will have greater potential for creation, manipulation, and destruction of life.

Human consciousness has created the agricultural age, the industrial revolution and now the information age. Humans have nuclear weapons of mass destruction that can end our world’s human habitation. The only note of optimism is that the history of human consciousness has generally led to positive changes for humanity, i.e., longer life spans, improved economic and social conditions, and new discoveries about life and living. The world is at its next great social and economic change.

THE BUSHY TREE OF LIFE

The Story of Evolution in 25 Discoveries

By: Donald R. Prothero

Narrated by: Tom Parks

Donald Prothero (Author, Amerivcan geologist, paleongologist,)

Donald Prothero provides a mountain of evidence informing the skeptical of the truth of evolution. Prothero explains evolution is a random and bushy process requiring time, heat, and a few basic chemicals to produce life. On the one hand, that makes life probable somewhere else in the universe. On the other hand, it implies human beings may be as ephemeral as dinosaurs, and dodo birds.

Prothero’s name makes one think of the Greek god, Prometheus, the creator of fire and mortals.

From the primordial soup of four or five billion years ago, the chemicals of life combine to create a self-reproducing cell. Within that cell, the genetic material of life is formed. As time passes, these cells combine to form life that adapts to its environment. This adaptation is the definition of evolution.

Prothero explains evolutionary adaptation both resists change, and commands change.

He gives the example of Giraffes that grow long necks but retain a nerve fiber that is longer and poorly located for its purpose. In battles for female attention, the evolutionary change of longer necks increases dominance of an evolved Giraffe over other male Giraffes with shorter necks. Though neck length improves procreation potential, the adaptive failure of the nerve fiber makes a long-necked Giraffe more vulnerable to injury. In a sense, evolution is an arbitrary process that often leaves useless remnants of body parts that do not serve a purpose and may hasten extinction.

What comes to mind as one listens to Prothero is that human beings are still evolving. Whether evolution will ensure survival or hasten extinction is unknown.

How are the human brain and body evolving? This is particularly important with a growing understanding of DNA and sciences’ ability to change DNA in a human subject. Is knowledge of DNA modification a function of evolution or revolution? Evolution has historically been a long-term process that may be less long term in the modern age.

What about Artificial Intelligence? Will A.I. become a part of human evolution? Is A.I. the next stage of human evolution or its replacement?

Prothero notes evolution is a bushy process meaning that variations of living organisms remain alive at the same time. Like whales, elephants, giraffes, and humans there are different evolutionary examples within species. Will there be humans that become a part of A.I. existence and others who will be exclusively human? Will one form of human become dominant? Prothero’s point is that evolution is not a linear process. There is no missing link that shows man evolving from apes. There is only one tree of life showing bushy branches with similar genetic material. Prothero notes 99.99 percent of human’s genetic make-up is the same. Chimpanzees are 98.8 percent similar, cats 90%, and honeybees 44%.

The close association of human DNA with chimpanzees shows who’s bushy tree to which we belong.

As Prothero notes, nature’s evolutionary change is not moral. Evolution is change based on nature’s random selection. Prothero suggests natural selection is a two-way street. Humans may have come from the sea, but whales are likely to have come from the land.

Prothero suggests humans have not changed much in the last thousand years. Memes have changed but little physical changes are evident. When human genetic manipulation takes control, morality becomes a human decision. With A.I., who knows where or how moral decisions will be made?

The Dragons of Eden

By: Carl Sagan

Narrated by: JD Jackson, Ann Druyan

Carl Sagan (1934-1996, Author, University of Chicago entry at 16 years of age, received a Master of Science and Doctor of Philosophy in astronomy and astrophysics in 1960.)

Carl Sagan died from a bone-marrow disease at the relatively young age of 62 in 1996. One generally associates Sagan with his Cosmos series, but his education went far beyond the study of astronomy. His book reflects as much on the philosophy of life as the future of society, science, and technology.

Today’s controversial abortion question is forthrightly addressed by Sagan. He suggests “Right to Life” and a “Women’s Right to Choose” are politically and philosophically extreme ends of a rational argument on abortion. “Right to Life” followers insist all life is precious even though humans kill animals for sport and consumption. “Women’s Right to Choose” followers insist birth of a baby in utero is the sole decision of women because their body and life are only theirs to control.

Sagan suggests a baby in utero in the first trimester may be tested for brain activity and if none is found, no personhood is formed. With no brain activity of a baby in utero, the right of a woman to choose is an equal rights decision. However, to Sagan if brain activity is present, life is present, and abortion is murder. Sagan infers a science based national law could be created that avoids the extremist positions of the “Right to Life” and “Women’s Right to Choose” movements.

Though Sagan may have overemphasized the difference between left brain and right brain function, he notes the advances that have occurred in how specific areas of the brain compete and can be electrically stimulated to elicit thought and action.

Sagan notes how computer gaming opens doors to the advance of computer capability and utility.

Nearly 50 years ago, Sagan’s book suggests much of what has happened in the science of brain function and technology. It seems a shorter step from Sagan’s ideas about computer function to what is presently called artificial intelligence. His view of brain and computer function might lead to a machine/brain confluence. It may be that Sagan’s belief in other forms of terrestrial life are secondary rather than primary interests of our human future.

In 1978, Sagan receives the Nobel Prize for nonfiction with “The Dragons of Eden”. In retrospect, it seems a wise decision by the Nobel panel of judges.

River out of Eden

By: Richard Dawkins

Narrated by: Richard Dawkins, Lalla Ward

RICHARD DAWKINS (ENGLISH ETHOLOGIST AND EVOLUTIONARY BIOLOGIST WHO INFERS A GENE MAY BE THE SOURCE OF CONSCIOUSNESS.)

As Dawkins’ clever title infers, “River out of Eden” is a scientist’s explanation of how life began and proliferates whether God exists or not. One can argue it is neither a refutation nor affirmation of God, only that God has nothing to do with life’s persistence. Dawkins’ explanation is based on Darwinian evolution and what he characterizes as the immortal gene. A human gene’s immortality is being tested by earth’s environmental degradation. On the other hand, immortal genes may adapt to earth’s degradation.

One cannot help but think of the potential of artificial intelligence and the future of human beings as they may evolve.

The discovery of DNA by Francis and Crick may change the course of human evolution. With the discovery of CRSPR, the medical community acquired tools that can modify genes. With those discoveries, it became possible to rid humanity of disease and hasten human evolution. Some argue these discoveries will improve human life; others suggest it will end it.

The discovery of the double helix. Erwin Chargaff (1951): Rule of Base pairing. Rosalind Franklin & Maurice Wilkins (1953): X-ray diffraction pattern of DNA. James Watson & Francis Crick (1953): Molecular structure of DNA.

Dawkins offers numerous examples of species that have evolved over millenniums of earth’s existence. He argues that survival is a result of an innate characteristic of genetic material that has the sole purpose of self-preservation. Genes are reproducing engines of life based on the environment in which they exist. Dawkins argues genetic materials’ ability to modify and replicate themselves are the essence of life’s continuation.

Evidence of Dawkins belief began with Darwin and is reinforced by numerous science experiments showing generations of birds, bees, and other forms of life that have inherited behaviors through generations of existence. His argument is that life is a matter of genetic predilection and preservation, more than learning.

The unexplored consequence of Dawkins’ belief is–what nature has provided to evolution, may soon be controlled by human beings. Genetic manipulation will no longer be determined by nature’s circumstances but by humankind’s limited knowledge. Considering human decisions that have murdered millions, earth’s ecological crisis, and human nature’s innate desire for money, power, and prestige, humanity should sense what Kierkegaard called fear and trembling.
