Physics for Future Presidents: The Science Behind the Headlines

By Richard A. Muller

Narrated by Peter Larkin

RICHARD A. MULLER (PROFESSOR OF PHYSICS @ UNIVERSITY OF CALIFNIA, BERKELEY) — RICHARD A. MULLER (PROFESSOR OF PHYSICS @ UNIVERSITY OF CALIFORNIA, BERKELEY)

“Physics for Future Presidents” suggests understanding of practical physics is critical for future Presidents. Richard Muller’s argument is that Presidents need to know some physics to comprehend the utility of everything from energy, to manned space flight, to satellite surveillance, to terrorist use of nuclear bombs. Muller is not arguing that future Presidents need to understand the science of physics but the practical limitations of manned space flight, carbon-based energy, satellite intelligence, and weapons of mass destruction (WMD).

Muller begins his book with the modern world’s effort to understand and contain terrorism. Muller’s book seems apropos based on President Trump’s effort to limit science research, discount CIA and FBI intelligence, and denuclearize North Korea.

TRUMP AND KIM MEETING — President Trump’s effort to limit science research, discount CIA and FBI intelligence, and denuclearize North Korea.

Muller explores the possibility of a terrorist organization building a nuclear bomb and detonating it in the middle of an American City. He looks at the possibility from three perspectives. One, difficulty in acquiring fissionable material; two, difficulty of building a nuclear device and three, difficulty in delivering a weapon of mass destruction to a desired location.

Surprisingly, Miller suggests a greater danger is terrorist attack by private planes, loaded with highly flammable fuel. Or, for a terrorist organization to use chemical and biological agents that directly or indirectly infect population centers.

CHEMICAL ATTACKS — Surprisingly, Miller suggests a greater danger is terrorist attack by private planes, loaded with highly flammable fuel. Or, for a terrorist organization to use chemical and/or biological agents that directly or indirectly infect population centers.

9.11.01TRADE CENTER ATTACK — Muller reasons a future terrorist attack (with 1000s killed) will be like 9/11, but with a private plane filled with fuel (not a nuclear bomb) flown into a major entertainment event.

Miller believes practical physics will determine the next world terrorist attack. Miller argues that the simplest plan will have the greatest impact. (Of course, there is also the implied psychology of terrorism.) Muller reasons a future terrorist attack (with 1000s killed) will be like 9/11, but with a private plane filled with fuel (not a nuclear bomb) flown into a major entertainment event.

There are a number of counter-intuitive insights in “Physics for Future Presidents”. Muller believes manned space flight is a waste of money. He argues that most of the greatest innovations in science have come from unmanned space flight. Weather satellites, spy satellites, entertainment satellites, global positioning satellites, drones, exploration of planets and the solar system have all come from unmanned space flight. Muller believes there is a time for manned space flight but not now. It is too dangerous and produces little new-science. He implies America should primarily invest in unmanned space flight.

CURIOSITY--FIRST -SELFIE- IN 2015 ON MARS — CURIOSITY–FIRST -SELFIE- IN 2015 ON MARS (Muller believes there is a time for manned space flight but not now. It is too dangerous and produces little new-science. He implies America should primarily invest in unmanned space flight.)

DR. STRANGLOVE — Dr. Strangelove- Richard Muller, at times, seems to stand at the side of fictional character Dr. Strangelove.(Movie titled “How I Learned to Stop Worrying and Love the Bomb)

Richard Muller, at times, seems to stand at the side of fictional character Dr. Strangelove. He describes historical information about radiation poisoning from nuclear bombs and accidents. Muller notes that statistical deaths from war (the Nagasaki and Hiroshima bombing), Three Mile Island, and Chernobyl show that deaths from nuclear radiation is small in comparison to terrorist events initiated by simple, practical, and conventional physics.

Muller argues that nuclear power can be used as a fail-safe source of energy by using the latest technology for nuclear power plants. The latest technology (actually first used in the 1960s by Germany) is a pebble bed reactor (PBR). It is considered safe because it does not rely on water cooling of the nuclear core in the event of an accident.

PEBBLE BED REACTOR IN WEST GERMANY – Muller argues that nuclear power can be used as a fail-safe source of energy by using the latest technology for nuclear power plants. The latest technology (actually first used in the 1960s by Germany) is a pebble bed reactor (PBR). It is considered safe because it does not rely on water cooling of the nuclear core in the event of an accident.

YUCCA MOUNTAIN NUCLEAR WASTE DEPOSITORY NEAR LAS VEGAS, NEVADA (Richard Muller believes Yucca Mountain is an adequately safe repository for nuclear waste that should be reopened.)

This is unlikely to be a popular book in Las Vegas, Nevada. Among other controversial subjects, Richard Muller believes Yucca Mountain is an adequately safe repository for nuclear waste that should be reopened. His argument largely rests on the science of probability. Muller infers that natural radiation in Colorado is as toxic as the probability of radiation leaks from stored nuclear waste at Yucca Mountain.

Muller argues that revision of nuclear construction standards in the United States would make construction of pebble bed reactors less expensive than conventional American nuclear facilities. The added benefit is a safer energy source that reduces the need for carbon based energy supplies that increase global warming. A large part of Muller’s argument for the use of more nuclear power is based on the generally accepted scientific belief that global warming exists and is most likely caused by human activity.

Muller spends a great deal of time explaining that global warming is not a 100% certainty but, in probability terms, is highly likely and largely related to carbon-based energy use. He notes that use of carbon-based energy is likely to increase with China and India’s continued economic growth. Muller creates a sense of urgency in creating other sources of energy. He strongly urges increasing motor vehicle mileage requirements but questions the viability of battery operated vehicles. Muller believes the costs of battery replacement will drive consumers back to carbon-based energy models.

ELON MUSK ROLLS THE DICE AGAIN BY PURCHASING SOLAR CITY, THE LARGEST SOLAR CONVERSION COMPANY IN THE U.S.–Muller sees potential in solar and wind energy production but believes conservation will do more short-term good than any new source of energy.

Muller sees potential in solar and wind energy production but believes conservation will do more short-term good than any new source of energy. He clearly sees that the cost of energy is the primary driver of technological innovation. As long as oil and coal are less expensive than other sources of energy, they will remain the primary source of power. With that realization, Muller insists on technological innovation in conservation because it motivates the consumer to become a part of the energy-crises’. Consumer’ participation is guaranteed by savings received from use of more energy-efficient devices.

The key to the world’s future is energy. Muller believes the short-term solution is conservation. He believes long-term solution revolves around nuclear fission and fusion. Fusion is a longer term prospect but offers an infinite source of energy. Fission is shown to work now, with probabilities of failure that can be improved upon.

This circles back to the critical importance of storing nuclear waste. Muller notes that the fragmented system of nuclear storage in the United States is a bigger risk to the environment than having it located in a limited number of specifically designed storage locations. Yucca Mountain fits Muller’s criteria for safe storage of nuclear waste. He acknowledges that nuclear accidents may occur but the probability of an accident at Yucca Mountain is less than the probability of accident at other relatively unsecured and fragmented sites.

The physics that Muller insists Presidents must understand is that scientific proof is a matter of probability; not absolute certainty. Muller warns Presidents to not be misled by cherry-picking fact finders that have objectives that are not related to practical physics. Even if there is no certainty in science, knowing probabilities offer a basis for informed decision.

TODAY’S LUDDITES

The Glass Cage-Automation and Us

By: Nicholas Carr

Narrated by: Jeff Cummings

NICHOLAS G. CARR (AMERICAN WRITER-FORMER EDITOR OF HARVARD BUISNESS REVIEW)

NICHOLAS G. CARR (AMERICAN WRITER-FORMER EDITOR OF HARVARD BUSINESS REVIEW)

The Glass Cage, written by Harvard alumnus Nicholas Carr, ironically places him in the shoes of an uneducated English textile artisan of the 19^th century, known as a Luddite.

Luddites protested against the industrial revolution because machines were replacing jobs formerly done by laborers. Just as the Luddites fomented arguments against mechanization, Carr argues automation creates unemployment and diminishes craftsmanship.

WORKMEN TAKE OUT THEIR ANGER ON MACHINES DURING THE INDUSTRIAL REVOLUTION. (Just as the Luddites fomented arguments against mechanization, Carr argues automation creates unemployment and diminishes craftsmanship.)

Workmen take out their anger on the machines

Carr carries the Luddite argument a step further by inferring a mind’s full potential may only be achieved through a conjunction of mental and physical labor. Carr posits the loss of physical ability to make and do things diminishes civilization by making humans too dependent on automation.

There is no question that employment was lost in the industrial revolution; just as it is in the automation age, but jobs have been and will continue to be created as the world adjusts to this new stage of productivity.

Unquestionably, the advent of automation is traumatic but elimination of repetitive industrial labor by automation is as much a benefit to civilization as the industrial revolution was to low wage workers spinning textile.

The Covid19 pandemic of 2020 will accelerate world’ transition to automation. Though this book is written earlier than the pandemic’s economic consequence, corporations are reevaluating the necessity for office buildings to conduct their business. More and more employees will work from home.

Employment adjustment is traumatic. The trauma of this age is that work with one’s hands is being replaced by work with one’s brain. The education of the world needs to catch up with socio-economic change; just as labor did in the 20^th century. To suggest humans do not learn when they cannot fly a plane, build a house, or construct an automobile with their own hands is a specious argument.

Houses and cars have not been built by one person since humans lived in caves and iron horses replaced carriage horses. Houses and cars were built by teams of people who worked with their hands but only on specific tasks. Those teams of people were managed by knowledge workers.

Service and education for society are the keys to the transition from industrialization to automation.

Automation of tasks reduces the mind numbing, low pay work of laborers. Automation turns manual labor into the development and education of people who design hardware and software to execute tasks that result in more safely flown planes, new houses, new cars, new refrigerators, so on and so on.

Carr suggests that airplane pilots should be given more control over automated planes they fly despite the facts he quotes that clearly show plane crashes kill fewer people today than ever in history. They are bigger, faster, and more complicated to fly. The argument that pilots need to learn how to fly a jumbo jet when automation fails is like telling a farmer to pull out his scythe to harvest the wheat because the thresher quit working.

Carr’s argument is that pilots have forgotten how to fly because automation replaced their skill set. To state the obvious, planes are not what they were 100 or even 10 years ago.

One might argue that Boeing’s 737 Max mistakes are evidence that Carr is correct in suggesting planes have become too complicated, but it ignores the reality of mistakes have always being made by humans. Humans are preternaturally motivated by self-interest.

Boeing’s leaders made mistakes in not fully analyzing and disclosing risks of 737 changes, and in not adequately training airline pilots on the safety features of the plane.

Carr raises a morality argument for not saving life when an automated machine makes a decision rather than a human being. One can suggest an example of how an automated machine is more likely to make the right decision than a human.

For example, presume a driver-less car is programmed to save its occupant when an injured bicyclist is laying in the street around a blind curve. A fast moving automated car with a family inside, with mountain cliffs on both sides of the road, will drive over the bicyclist without conscience. The bicyclist is dead but the car passengers are alive. If the car is driven by a person, both the cyclist and the family are likely dead.

THINKING SLOW — Carr’s argument is that humans need to make their own intuitive decisions. As pointed out by Daniel Kahneman in “Thinking Fast and Slow”, the primary “think fast” mode in humans is intuition, which is often wrong.

Without doubt, many automation errors (e.g., the 737 Max) have been and will be made in the future, but to suggest automation is not good for society is as false as the Luddites arguments about industrialization.

This period of the world’s adjustment is horrendously disruptive. It is personal to every parent or person that cannot feed, clothe, and house their family or themselves because they have no job.

Decrying the advance of automation is not the answer. Making the right political decisions about how to help people make job transitions is what will advance civilization.

Mars Rover Curiosity: An Inside Account from Curiosity’s Chief Engineer

Written by: Rob Manning, William L. Simon

Narrated by: Bronson Pinchot

This antenna-tailed super dog, and a Rover named Opportunity, are in the news this month. After analysis of elemental particles by Curiosity, organic molecules are discovered. An astro-biologist at Utrecht University in the Netherlands suggests life may have existed or originated on Mars.

Curiosity is a mechanical, one-eyed, six wheeled, antenna-tailed super dog. It can stiff the air, drill rocks, analyze elemental particles, roam a countryside at a snail’s pace (300 feet per hour), and talk to humans. Its language is in 1s and 0s. It speaks to Earth from Mars across 49 million miles of space with a message that continues to amaze and encourage human exploration of the universe.

Curiosity Rover Animation:

Sadly, it was reported on February 13, 2019–that an earlier Mars Rover died. It was called Opportunity. Curiosity, according to a “Life Science” article, cannot repair Opportunity because of time and distance.

A slightly earlier Mars Rover called Sprit, a twin of Opportunity, died on March 20, 2010.

However, like the movie musical “Don’t Cry for Me Argentina”, we should not mourn their loss. Both of these earlier rovers outlast their expected lives. In addition to “Curiosity”, more is yet to come. On this Thursday, 2.19.2021 @ 3:55 pm EST, a new rover named “Perseverance” is scheduled to land in the Jerzero Crater of Mars.

Robert Manning, in collaboration with William Simon (a ghost writer), reflects on the technological feat of creating and delivering a robotic laboratory to the fourth rock from the sun.

Curiosity launched on November 26, 2011 to arrive on Mars August 6, 2012. It landed on the Aeolis Palus plain, a crater that may be an ancient lake bed. Robert Manning, in collaboration with William Simon (a ghost writer), reflects on the technological feat of creating and delivering a robotic laboratory to the fourth rock from the sun. Manning heads a team of NASA scientists and engineers to design the latest land rover, called Curiosity, to explore Mars.

The first 12 months of Curiosity’s First Year on Mars:

In June 2018, Curiosity continues to explore Mars and deliver information on the history of earth’s mysterious neighbor.

What Curiosity is Discovering:

Curiosity is meant to search for artifacts of life on Mars while testing the potential for colonization of another planet. To date, no definitive answers are given but Manning’s story suggests most of the building blocks of life were at one time present on Mars. Now, it appears Manning’s story is tentatively confirmed.

Life on Mars?:

The primary atmospheric conditions of Mars are made of carbon dioxide and some water vapor as opposed to nitrogen, oxygen, argon, and other elements of earth. The average temperature on Mars is 81 degrees Fahrenheit versus 57 degrees on Earth (a misleading metric because of the huge extremes on Mars). Mars gravity is only .375 that of Earth which has significant ramification for sustainability of human life on the planet.

No indisputable historical evidence of life on Mars has been discovered but the existence of fluctuating amounts of methane in the atmosphere may mean Mars is geologically active and holds the potential for microscopic life. Methane contains hydrogen and carbon but, with little discovered oxygen, there is limited chance of any life form representative of earth; at least, that is larger than a microbe.

“Mars Rover Curiosity” and “Perseverance” are a tribute to NASA and its organizational skill in achieving a land mark experiment in human exploration. In listening to Manning’s story, one feels they are on the edge of a continent in the 15^th century, planning to sail to an unexplored place to find answers about what there is beyond imagination.

In listening to Manning’s story, one feels they are on the edge of a continent in the 15^th century, planning to sail to an unexplored place to find answers about what there is beyond imagination. NASA’s contribution to science and a possible future for humanity seems inferred by Manning’s story; particularly in light of current scientific evidence for Earth’s global warming.

Curiosity’s exploration (though only a mechanical creation of NASA) reminds one of Marco Polo, Vasco da Gama, Christopher Columbus, Magellan, Cortes, and Neil Armstrong in their discovery of new continents.

The Island of Knowledge: The Limits of Science and the Search for Meaning

Written by: Marcelo Gleiser

Narration by: William Neenan

MARCELO GLEISER (BRAZILIAN PHYSICIST AND ASTRONOMER, PHYSICS AND ASTRONOMY PROFESSOR AT DARTMOUTH)

MARCELO GLEISER (AUTHOR, BRAZILIAN PHYSICIST AND ASTRONOMER, PHYSICS AND ASTRONOMY PROFESSOR AT DARTMOUTH)

Marcelo Gleiser believes an A.I. singularity predicted by Ray Kurzweil is a myth of science that will be stranded on “The Island of Knowledge”. His point is that the nature of science, human cognition, and quantum physics make computers incapable of superseding or equaling human intelligence. The horizon of the unknown will always be present for human beings, even with computational advances. Gleiser implies that the computer will only be a tool of humankind to explore the unknown.

Gleiser notes the nature of science is to explain natural phenomena. Sciences’ explanations create an island of knowledge that is like Plato’s Socratic cave; i.e. a cave for humanity that only reveals shadows of reality.

PLATO’S CAVE (Gleiser suggests Sciences’ explanations create an island of knowledge that is like Plato’s Socratic cave; i.e. a cave for humanity that only reveals shadows of reality.

Human beings cannot leave the cave because every scientific discovery only leads to another question about shadows that represent the real thing. Gleiser prepares one for that conclusion by recounting the history of great scientists like Isaac Newton, James Maxwell, Max Planck, Earnest Rutherford, Albert Einstein, Edwin Schrodinger, Werner Heisenberg, Paul Dirac, and others. Each of these scientists contributes to “The Island of Knowledge” but each raises more questions about phenomena that remain shadows of nature’s reality.

Gleiser acknowledges that Newton and Einstein sharpen shadowy outlines of nature’s reality but each fails to discover absolute truth. Newton misses the fundamental truth of time. Einstein misses the truth of quantum physics. Newton’s time is relative and Einstein’s presumed certainties are probabilities.

SIR ISAAC NEWTON (1642-1727)

Albert Einstein (1879-1955)

Gleiser argues that human cognition is limited by “The Island of Knowledge” because cognition is influenced by the mind’s senses. For example, history is reported with facts that are selected by the historian. The facts may be accurate but not all facts of the past are reported and thereby history becomes a shadow of the truth.

In science, experiments do not prove truth; i.e. experiments only eliminate false positives, leaving only another experiment to disprove another presumed truth. Experiments theoretically get one closer to a truth but the truth remains a shadow because the new truth has to be explored by further experiment. As Karl Popper notes: “In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality.”

KARL POPPER (1902-1994) Popper suggests there are no verifiable truths; only probabilities. If so, A.I. (at least) has the potential for improving the odds of factual truth.

Gleiser implies the idea of a Turing Computer that can know the origin of life is as specious as belief in the myth of the Holy Grail. Gleiser explains that artificial intelligence will never supersede or equal human intelligence because natural phenomena are found to be probabilistic and not defined by yes and no, or ones and zeros. Artificial Intelligence is a misnomer.

Finally, Gleiser suggests artificial intelligence will never supersede or equal human intelligence because natural phenomena are found to be probabilistic and not defined by yes and no, or ones and zeros. Artificial Intelligence is a misnomer in Gleiser’s opinion.

AI is a man-made construct, subject to “The Island of Knowledge” created by human beings. Gleiser argues there are serious dangers in expansion of AI because it reduces complexity to yes and no answers. One wonders if Gleiser takes into consideration experiments being conducted with quantum computing. These experiments are meant to create a neural network that emulates human consciousness but with improved probabilistic calculations.

Gleiser’s implication is that a computer that programs itself becomes a Frankenstein; not a sentient being. He argues that A.I. creations are likely to disrupt, if not destroy, human life. He believes A.I. will always be based on shadows of unverifiable truths.

Gleiser implies the idea of a Turing Computer that can know the origin of life is as specious as belief in the myth of the Holy Grail. He may be right. Although, Popper suggests there are no verifiable truths; only probabilities. The Holy Grail is a myth because nothing can ever be absolutly proven. If so, A.I. seems to have the potential of improving the odds of factual truth.

Gleiser touches on the mysteries of “spooky action at a distance” which challenges Einstein’s dictum that nothing exceeds the speed of light. Gleiser recounts experiments that prove “spooky action at a distance” are real.

Experiments with “spooky action at a distance” open a new field of inquiry. This and “string theory” are examples of challenges to belief that human beings will ever have a theory of everything. A.I. seems a credible tool for further experimentation. whether it is a “Frankenstein” or not.

Gleiser believes “The Island of Knowledge” is as close as humanity will ever get to a theory of everything and it will always be a shadow of nature’s truth. Karl Popper would agree. Gleiser is saying pursuit of truth is important but precise truth is unattainable. He argues that a final truth will never be found because discoveries of science will only lead to more questions, more experiments, and better tools of measurement. Nature’s truth will always be beyond human understanding; i.e. at best, nature’s truth will only be shadows of reality with sharper outlines. Humanity may not be capable of escaping the cave to discover the truth of life.

Gleiser is quick to point out that his concept of the human island of knowledge is not meant to discourage scientific exploration. He believes human beings have an innate desire to understand nature. Life experience suggests wanting to understand nature is true of all cultures because humanity desires immortality.

Humans want to think of themselves as the center of the universe; as false as that may be.

Philosophy of Science

By: Professor Jeffrey L. Kasser

Narrated by Professor Kasser Lecture Series

DR. JEFFREY L. KASSER (ASSISTANT PROFESSOR OF PHILOSOPHY AT COLORADO STATE UNIVERSITY)

This is a tough audiobook to adequately summarize. Dr. Jeffrey Kasser offers evidence for the value and advance of human knowledge through philosophy and science. Kasser explains that philosophy is the beginning of what becomes a scientific world view. Kasser attempts to drag skeptics out of Socrates’ cave with a “36 lecture” series titled “The Philosophy of Science”.

Kasser recounts the history of science from a world controlled by fickle gods to a world of cause and effect. Then, in the early twentieth century, Kasser notes that science reveals a world of probability. Kasser reports on views of science changed by philosophers like Karl Popper, Paul Feyerabend, and Bas van Frassen.

KARL POPPER (1902-1994) Popper suggests science cannot be proven but only falsified. His point is that only infinite experimentation can prove the truth of a scientific theory.

Infinity, by definition, is boundless; therefore, science offers limited truth in so far as no one can reach an infinite number of experiments to prove a theory.

PAUL FEYERABEND (1924-1994)

Feyerabend argues that scientific method is a constraint rather than exploratory tool of science. To Feyerabend, when science begins with hypothesis, research is restricted and experimentation becomes biased by pre-conceived or experienced perception.

Bas van Fraasen (Philosopher)

Bas van Fraassen suggests that, at best, science can only reveal approximate truth about the physical world. His view lends itself to quantum physics where cause and effect become probabilistic rather than definitive.

These three philosophers, as well as several others noted by Kasser, steer science to a category of understanding called logical positivism. Logical positivism is argued to be the primary focus of what is called good science. Logical positivism suggests that science must be based on direct experience and logic; within limitations like those argued by Popper, Feyerabend, Frassen, and others.

However, Kassen suggests even logical positivism is challenged by the realization that acts of analysis, particularly measurement of results, distort reality.

Distortion comes from the act of measurement and the bias of human cognition. In other words, experiments done by different scientists with the same results remain only qualified scientific truths. Experimentation, even accompanied by logic, becomes suspect. Observational measurement and human perception are critically important to science but, by nature, both measurement and perception taint objective truth.

Kasser explains the truth of science lays in experiment designed to disprove hypothesis. Logic generates hypothesis. Hypothesis is tested for falsity through experiment. Experiment requires measurement. Science experiment is influenced by measurement and human perception which raises doubt about results of tested hypothesis.

SIR ISAAC NEWTON (1642-1727) Kasser notes that Newton’s laws infer a cause-and-effect world

Newton’s laws work in the macro world. We no longer believe rocks fall to the ground because they live there. Newton’s laws of motion suggest that a bowling ball and a basketball will fall at the same rate of speed, even though their mass is different. This is experimentally and logically provable. If a rock, bowling ball, or basketball are picked up and dropped, they will fall to the ground. If they are in a vacuum, they will fall to the ground at the same rate of speed.

In the micro world, components of atoms that combine to form what we see as bowling balls and basketballs cohere to each other in a way that does not conform to Newton’s laws. The components of atoms operate in accordance with quantum mechanics which shows that elements of atoms in bowling balls and basketballs do not follow Newton’s laws of motion. The orbital planes of atomic elements like quarks and leptons appear and disappear; i.e. they do not follow a predictable pattern of action.

Cause and effect in the macro world is replaced by probability in the micro world.

None of this is to suggest that Newton’s laws are false or that quantum mechanics are anything more than an expansion of Newton’s laws. However, at this stage of scientific discovery, the two laws are not compatible even though both laws are experimentally confirm-able. Attempts have been made to unify these laws. String theory is the present day most studied hypothesis but it fails the criteria of null hypothesis because of today’s instrumental and cognitive limitations.

Philosophy and science are integral to the advance of human civilization. We are still looking at shadows of reality but Kasser infers philosophy and science are the best hope for Socrates’ spelunkers.

NUCLEAR POWER

Atomic Accidents: A History of Nuclear Meltdowns and Disasters

By James Mahaffey

Narrated by: Tom Weiner

Listening to Atomic Accidents, the first thing that comes to mind is point-of-view, second the author’s qualification, and third writing skill. Mahaffey’s book is historically fascinating, and enlightening. And happily, Mahaffey writes well.

Doctor James Mahaffey’s professional career is founded on the nuclear industry. Educated at the Georgia Institute of Technology, Mahaffey holds a bachelor’s degree in physics, a master’s in science, and doctoral in nuclear engineering.

Mahaffey is well versed in the science, engineering, and mechanics of nuclear energy. Because of education, one presumes Mahaffey is a proponent of the nuclear power industry. After dissection of several atomic accidents, a listener becomes unsure of Mahaffey’s point of view. By the end, his point of view is clear.

nagasaki bombing aftermath — The best known nukes, Big Boy and Little Boy, were dropped on Hiroshima and Nagasaki at the end of WWII.

America has dropped and lost nuclear bombs around the world. The best known nukes, Big Boy and Little Boy, were dropped on Hiroshima and Nagasaki at the end of WWII.

Less known bomb drops were in peace time. Nukes were accidentally released on remote military bases, in sparsely populated residential areas, and in the sea. Some of those dropped in the sea remain unrecoverable. None of the peace time bombs exploded.

America chose to keep nuclear secrets from Great Britain after WWII because of concern over nuclear bomb proliferation. Because of America’s secrecy and lack of cooperation, Mahaffey suggests design mistakes were made.

In reviewing the history of nuclear energy, Mahaffey notes English scientists and engineers designed graphite nuclear power plants that were inherently dangerous. Graphite catches fire at high temperatures and is notoriously hard to extinguish. However, graphite nuclear plants became widely copied throughout the world.

Mahaffey’s stories of nuclear mishaps range from dumb to dumber; i.e. from wind fans that feed graphite nuclear plant fires to technicians that ignore rules of reactor management. Nuclear accidents seem inevitable and insurmountable.

CHERNOBYL NUCLEAR REACTOR (e.g. A FAMOUS GRAPHITE REACTOR ACCIDENT.) — CHERNOBYL NUCLEAR REACTOR ( Chernobyl is an example of a major graphite nuclear reactor failure.)

Mahaffey explains that the former U.S.S.R. ignored environment in their nuclear bombs race with America. They dumped plutonium in Russian waters and blew up a graphite nuclear plant that killed Russian workers in a steam explosion. The explosion contaminated miles of Russian homeland with radioactive fallout.

Later, the U.S.S.R. mismanaged Chernobyl’s nuclear facilities and created a nuclear meltdown that reportedly killed over 60 people from radiation and left an area of Russia uninhabitable for generations to come.

FRANCIS GARY POWERS (1929-1977, CAPTAIN IN THE US AIR FORCE, SHOT DOWN OVER RUSSIA IN 1960 AND HELD PRISONER FOR 2 YEARS) — FRANCIS GARY POWERS (1929-1977)

Mahaffey tells the story of the American, Gary Powers, the pilot shot down by the Russians in the 1950s. Powers is taking aerial pictures of plutonium manufacturing facilities in the U.S.S.R. Eisenhower is compelled to lie and then apologize to Russia for the clandestine operation. Mahaffey makes the story interesting by revealing the monumental effort made by the U.S.S.R. to shoot down Powers’ airplane and reassemble plane parts to prove Powers was spying.

FRANCIS GARY POWERS (DIES IN HELECOPTER CRASH WORKING AS KNBC WEATHER PILOT) — FRANCIS GARY POWERS (DIES IN A 1977 HELECOPTER CRASH WORKING AS KNBC WEATHER PILOT)

In the end, Mahaffey discounts the many nuclear accidents and incidents he examines. His conclusion is that nuclear power can be made probabilistically safe. Mahaffey argues for the design of nuclear energy facilities that are small and simple to operate. He suggests that small nuclear power plants be designed and manufactured for specific industrial facilities.

Rolls Royce is entering the nuclear facilities market in Great Britain. Small nuclear plants could meet industrial energy demands while limiting environmental carbon emission from other sources of energy Rolls Royce Small Nuclear Plant Production

With small nuclear energy plants, the potential for catastrophic Chernobyl-like’ events would not happen. The massive underwater earthquake and tsunami would not have decimated Japan’s nuclear energy capability if the power plants had not been so massive and concentrated on the coast.

Mahaffey implies proper design and training for small, simple nuclear energy facilities will mitigate the world energy crises. Mahaffey infers nuclear accidents are unavoidable, but human and environmental damage is minimized with smaller nuclear energy plants.

Rolls-Royce recently (in November 2021) announced they are getting into the small nuclear reactor business.

Mahaffey explains that radiation is a naturally occurring phenomenon. He argues that shutting down nuclear waste disposal facilities like Yucca Mountain in Nevada are a mistake. Many in Las Vegas oppose President Trump’s resurrection of the Yucca Mountain waste site.

Mahaffey’s point of view is that nuclear power accidents will happen but their consequences can be minimized with smaller plants and better planning for treatment of victims when accidents occur. He believes nuclear energy benefits far out weigh their risks.

The 2020 Presidential election is over. President Biden’s campaign speaks to America’s gradual transition from fossil fuels to wind, water, and solar power. That transition is a potential source for thousands of new American jobs. Mahaffey persuasively argues there should be a place for nuclear energy in that transition.

GOD’S EXISTENCE

36 Arguments for the Existence of God
By Rebecca Newberger Goldstein
Narrated by Stephen Pinker, Rebecca Newberger Goldstein, Oliver Wyman

Rebecca Goldstein writes like Stephen Pinker on steroids. (Coincidentally, Goldstein is married to Pinker.) Goldstein’s novel is not the story one expects from its title because “36 Arguments for the Existence of God” is about denial; not affirmation of existence.

STEVEN PINKER (Cognitive psychologist, linguist, and author) — STEVEN PINKER (Cognitive psychologist, linguist, and author who wrote “How the Mind Works”, “The Blank Slate”, “Angels of Our Better Nature”, etc.)

A more apt title for Goldstein’s book might be “The Science of Human Nature Denies the Existence of God”.

Goldstein has done a masterful job of creating “fear and trembling” in believers. This is “fear and trembling” in the opposite sense of Soren Kierkegaard’s meaning. Kierkegaard’s meaning awakens believers in God. Kierkegaard, an author, theologian, and philosopher, argues one should fear and tremble at the truth of God’s existence.

On one level this is a story about a man named Cass Seltzer and his personal (sometimes romantic) relationships.

On a second level it is about human ethnocentrism. Characters, including Cass Seltzer, see through myopic eyes based on who they have become and what peer group they belong to.

On a third level “36 Arguments…” is about human nature and cultural memes (Richard Dawkins defines a cultural meme as an inherited learned behavior).

On multiple levels, Goldstein’s writing is about the elephant in the room; i.e. mankind’s belief in a Supreme Being.

The story of Cass Seltzer’s life is absorbing. The women he loves are monumentally independent, fantastically alluring, and maddeningly self-centered (as self-centered as Cass Seltzer). Each character believes what they believe with conviction that directs their lives.

The introduction of Felix Fidley exemplifies tribal ethnocentrism and conviction; i.e. a believer who says one way is the only way.

RELIGIOUS BELIEF — Goldstein’s introduction of Felix Fidley in her novel exemplifies tribal ethnocentrism and conviction; i.e. a believer who says one way is the only way.

Ms. Goldstein cleverly introduces the town of New Walden. Its isolated belief system reflects the heritability of good and bad genetic markers and memes that trap people in worshipful repetition. One might categorize it as a cult or, more politely, a commune.

Finally, Goldstein creates a straw man debate about God, The debate is conducted in the next to last chapter. It pits Cass Seltzer against a purportedly renowned debater. Seltzer beats his debate opponent. Believers in God lose. In the last chapter, 36 arguments for belief in God are stated and refuted.

SCIENCE AND RELIGION — One doubts Goldstein will change the world with her book but its rational arguments are a big add to the non-believing world’s arguments for a scientific theory of the world that explains everything about everything.

PREACHER PREACHING — Faith is always a refuge but is it enough?

If you are a believer, “36 Arguments…” is a clear explanation of your battleground; it reveals the manifesto, strategy, and tactics of a non-believer. Faith is always a refuge but is it enough?

“36 Arguments for the Existence of God” is a fascinating piece of literature.

Death by Black Hole
By Neil deGrasse Tyson

Narrated by Don Graham

NEIL deGRASSE TYSON (AMERICAN ASTROPHYSICIST, AUTHOR, SCIENCE COMMUNICATOR.)

Neil deGrasse Tyson has become a famous translator of the science of cosmology for the layman because of appearances on Nova, and comedy programs like “The Daily Show”, “The Colbert Report”, and “Real Time with Bill Maher”.

“Death by Black Hole” is an exploration of the universe; i.e. how it was formed, where life comes from, whether life exists on other planets or in other universes, how the world might end, what a black hole in space is, and what would happen to the human body entering a black hole.

Tyson explores the molecular basis of creation. He notes how ethnocentric concepts of life have evolved from a belief in man as the center of the universe to man as a grain of sand in the desert; randomly placed by the “big bang” of creation.

Tyson describes man as a concretion of star dust molded by a molecular carbon based combination of atoms, super heated, cooled, and evolved over eons of cosmological time. He suggests that all planets may have forms of life. His evidence is the existence of extremophiles in earth environments. An extremophile is a living organism that survives in environments in which no human being could live.

THERMOPHILE ENVIRONMENT IN THE HOT SPRINGS OF YELLOWSTONE — ENVIRONMENT IN THE HOT SPRINGS OF YELLOWSTONE (Tyson writes of thermophiles, a type of extremophile that thrives in temperatures of 113 to 252 degrees Fahrenheit. )

Tyson writes of thermophiles, a type of extremophile that thrives in temperatures of 113 to 252 degrees Fahrenheit.

Tyson explores current understanding of an expanding universe, how it is measured through spectrographic analysis, and how expansion of the universe is accelerating.

He notes that the end of times for man may come from death of the sun, the turning of this universe’s white star to a red star to a black hole. Tyson notes that another possibility is that accelerating expansion of earth’s universe will cause a gradual cooling of the planet that will only allow extremophiles to survive.

Tyson suggests the most likely cosmological cause of the human race’s end is collision with an asteroid. Of course, the end that concerns us is humankind. Like Dyson’s explanation of the likely cause of dinosaur’s demise, human existence would disappear from the cataclysmic effects of a sunless planet hidden, cooled, and smothered by the debris of collision.

ASTEROID COLLISION WITH EARTH — Tyson suggests the most likely cosmological cause of the human race’s end is collision with an asteroid.

ET (FICTIONAL EXTRA TERRESTRIAL) — Tyson laughs at the idea of a movies creation of other life forms as distorted caricatures of human beings (like ET).

Tyson speculates about contact with extraterrestrials by noting that the general media fails to base concepts of other life forms on 20^th and 21^st century science. Tyson laughs at the idea of a movies creation of other life forms as distorted caricatures of human beings (like ET).

Tyson explains that SETI (Search for Extraterrestrial Intelligence) is a long shot to hear a transmission from space as a first sign of contact. He wonders if other intelligent life is listening rather than transmitting so that everyone is listening and no one is transmitting. On the other hand, Tyson recounts sciences’ effort to send a radio transmission to a star cluster that will reach its destination a 1000 years from now. Ironically, the high concentration of stars in that system, makes that particular star cluster a bad focal point for intelligible reception. Extraterrestrial radio wave contact seems unlikely, based on these first attempts.

SETI (LISTENING FOR ANYBODY OUT THERE) — SETI (LISTENING FOR ANYBODY OUT THERE–Tyson explains that SETI (Search for Extraterrestrial Intelligence) is a long shot to hear a transmission from space as a first sign of contact )

EFFECTS OF HUMAN DESCENT INTO A BLACK HOLE

As to the effects of a human body entering into a black hole. Tyson explains the human body would be stretched and contorted. Time and space are dissolved as you approach the event horizon. Before you reach the event horizon, your body is atomized.

Tyson explores the history of cosmology beginning with scientists like Newton, Galileo, Copernicus, Einstein, Durac, Hubble, and many other names known and unknown by the general public. “Death by Black Hole” is interesting but not fascinating. A number of videos on “you tube” summarize Tyson’s commentary.

WONDER OF THE WORLD

Knocking on Heaven’s Door
By Lisa Randall

Narrated by Carrington MacDuffie

LISA RANDALL (AMERICAN THEORETICAL PHYSICIST)

Lisa Randall believes the Large Hadron Collider (LHC) is one of the wonders of the world; competing with the pyramids of Egypt in its colossal achievement. Located near the border of France and Switzerland, it is the largest construction project ever built.

“Knocking on Heaven’s Door” is the story of the Collider’s creation, inner workings, and scientific objectives. Along the way, Randall explores physics, sciences conflict with religion, the process of scientific research, and somewhat ineptly, the near economic collapse of the financial world in 2007.

LHC MAP SHOWING CERN SITE — “Knocking on Heaven’s Door” inspires one to visit the site, near Geneva, Switzerland. Randall’s description is of a 17 mile tunnel that is the coldest and largest vacuum on earth, capable of hurtling particles near the speed of light to collide neutrons that are meant to separate into constituent parts.

Randall’s information about LHC inspires one to visit the site, near Geneva, Switzerland. Her description is of a 17 mile tunnel that is the coldest and largest vacuum on earth, capable of hurtling particles near the speed of light to collide neutrons that are meant to separate into constituent parts. The idea of such a creation challenges one’s understanding; its reality is remarkable. How is it possible to control a neutron? What is the point of causing neutron collisions? Why should anyone care about particles of matter that cannot be seen?

Randall, as a physicist, does a fairly good job of answering those questions for a non-scientist. Neutrons are a chosen accelerator particle because they are divisible. Neutron control is exercised by magnets around an elliptical tunnel that contain accelerating neutrons within a super cooled vacuum that pushes and pulls neutrons to keep them in line.

Neutrons are particles made up of smaller elements, scientifically confirmed through repeated experiments. The makeup of a neutron was found by forcing collisions between neutrons that broke into separate elements. However, not all parts of a neutron have been experimentally identified. Einstein’s balance between energy and mass multiplied by the speed of light squared shows an imbalance between known elements of a neutron and a neutron’s mass/energy equivalence. The imbalance may be the Higgs-boson particle.

This is where the picture gets a little fuzzy for the dim-witted (meaning this reviewer). The Higgs-boson particle is sometimes called the God particle. It is surmised to be the glue or medium of mass in the universe; i.e. the key to dark matter and energy that make up 75% of the known universe.

The consequence of finding Higgs-boson is unknown which is the bête noire of pure science. Scientists seek to know for the sake of knowledge; not necessarily for its practical consequence. Is it important? Was Einstein’s pure science important? Hiroshima and Nagasaki answer that query.

As is well-known, Higgs-boson has been discovered. HIGGS-BOSON DISCOVERY

A quibble one may have with Randall’s book is that she digresses into derivative finance to suggest that more scientific analysis would obviate the kind of financial disaster that occurred in 2007. She suggests that proper analysis of the risk of derivatives would have stopped the madness. The naivete of that argument is that there were only a few that saw the collapse coming. Scientific analysis only convinces some. The history of politics, ignorance, and power are shown to have more influence than science or rational thinking.

TRUMP AND CLIMATE CHANGE — The President of the United States believes he is acting rationally by ignoring science and deregulating industries believed to be huge contributors to global warming.

How different is expert analysis from the scientific community on global warming. Scientific analysis misses part of what makes human’s human; i.e. minds can know something and still act irrationally; not to mention, rationality is often in the mind of the beholder. The President of the United States believes he is acting rationally by ignoring science and deregulating industries believed to be huge contributors to global warming. Randal admits as much in writing about beauty and truth and clearly notes that they are not necessarily equivalent because of human subjectivity.

Randall convinces one of the formidableness of LHC and the potential of its contribution to science. America may have missed a chance to be a leader rather than follower of one of the great contributions to science, the Large Hadron Collider.

KNOWING NOTHING

Thinking Fast and Slow

By Daniel Kahneman

Narrated by Patrick Egan

There are certain knowns that are known and certain knowns that are unknown. Well, I know I know nothing and Kahneman seems to prove it. Every chapter of Kahneman’s book suggests something one finds hard to believe is true.

Daniel Kahneman is a renowned psychologist and Nobel laureate. He is an American citizen that served in the Israeli military and used his education, research, and experience to write “Thinking Fast and Slow”. His observations explore many aspects of human decision-making.

How one runs their business or lives their life is framed by how they think. Kahneman explores two fundamental ways of thinking that reveal human strengths and weaknesses. “Thinking Fast…” is intuitive and easy. It is prejudiced by personal life experience and education. It is activated through an evolved instinct that forms the basis for snap decisions. In contrast, “…Thinking Slow” is a deliberative, calculating, and mind-numbing way of making rational decisions. Kahneman calls these mental functions System 1 and System 2 respectively.

“…Thinking Slow” is undoubtedly prejudiced by Kahneman’s scientific interpretation of “human thought and action”’ but judgment of his observations is the responsibility of the reader or listener; so, caveat emptor.

The more common decision-making tendency of the brain is to use System 1 rather than System 2 when making decisions because it is easier and because, as Kahneman notes, behavioral studies and brain imaging show human brains are lazy (not inclined to use System 2’ thinking because it is more laborious than System 1).

System 1 often leads humans to make incorrect intuitive decisions. System 2 potentially improves probability of making better, or at least more rational, decisions. However, System 1 is important to life and death decisions that require instantaneous action. System 2 requires one to consider options before settling on an action. A current example is the dilemma of choice in regard to social media. Fighting hardly seems logical based on the direction of technology. Flight seems equally illogical for the same reason.

FIGHT, FLIGHT, LIGHT — System 1 is important to life and death decisions that require instantaneous action. System 2 requires one to consider options before settling on an action.

FIREMAN NARROWLY ESACAPES FLOOR COLLAPSE — FIREMAN NARROWLY ESCAPES FLOOR COLLAPSE ( Using System 1 thinking the fire commander tells his team to get out of a burning house because his mind subconsciously gathers experiential information telling him the floor is about to collapse.)

Kahneman gives a more concrete example with an experienced fire commander. Using System 1 thinking the fire commander tells his team to get out of a burning house because his mind subconsciously gathers experiential information telling him the floor is about to collapse. The fire commander’s system 1 thinking saved his team’s lives.

Kahneman contrasts the value of System 2 thinking by exploring System 1’s habit of unconsciously bench-marking manufactured product pricing to seduce consumers to buy at higher prices; i.e. if a product is priced high, System 1 thinking is willing to pay a higher price.

Attention — The “halo” effect caused by System 1’ thinking gives too much weight to a one time “good” interview evaluation of an employee candidate.

Another observation is that employee interviews are often detrimental to the selection of the best job candidate. Kahneman describes the “halo” effect caused by System 1’ thinking that gives too much weight to a one time “good” interview evaluation of an employee candidate. To protect from the “halo” effect, Kahneman suggests that interview questions be structured and an employment process be standardized to give more objective criteria for choosing the best employment candidate. In other words, design an employee selection process based on clearly defined job requirements that are equally measured and fairly weighted for each candidate. Employer hiring solely based on a candidate’s interview is not a good determinant of employee performance.

This brief review is a single drip of sweat in a twenty hour work out. Kahneman undoubtedly exaggerates the import of some scientific studies but his writing engages System 2 thinking. A System 2 person will want to listen to “Thinking Fast and Slow” more than once.
