Donald E. Brown shows us the universal truths of humanity, and the countless errors of anthropology

Human Universals – Donald E. Brown (1991)

In the course of reading a book, titled The Routledge Companion  to Ecstatic Experience in the Ancient World, I saw a footnote referencing a different book titled Human Universals.  I made the request through the Inter-Library Loan Program (ILL) and the book made its way to me.  In less than 160 pages, the author Donald E. Brown presents the many mis-steps, fallacies, and outright obfuscation entered into by anthropologists over the decades since the scientific field of anthropology began.  Specifically, Mr. Brown explains the many ways anthropologists sought to either prove or disprove the idea that certain traits, desires, and thoughts are universally found in all human societies and cultures.

To the everyday layperson, it would appear that there are many aspects of our lives that are universal to all humans, but much of the anthropological research in our collective past began with the assumption that the human mind is a blank slate at birth, and that all culture and society is created or instilled in a human after their birth by those around them.  This drew from psychological ideas which, wholly accepted one hundred years ago, are no longer seen as valid due to the countless years of neurological, genetic, and psychological research that we humans have endeavored upon.  Donald E. Brown spends several chapters discussing exactly how these old assumptions were put to the test, and how they were deemed erroneous.

It is one of the many aspects of anthropology that I found irritating while studying at university, and which I currently find frustrating in many of the “soft sciences.”  The Scientific Method relies on experimentation, rigorous data gathering, and the willingness for the researcher to admit their initial ideas are wrong when faced with evidence to the contrary.  The so-called “soft” sciences, anthropology, sociology, psychology, etc., tend to begin with purely abstract assumptions, and then to seek evidence of these assumptions in the world around us.  Anyone who has studied the ease with which a human being can be deluded or misled by their own strongly-held ideas, even in the face of overwhelming evidence to the contrary, can understand why Donald E. Brown spends so much time explaining the many fallacies and errors involved in the study of human universals.

There are basic elements of human life and culture that are obviously universal.  We are all born, and we all die.  We must all eat other living things for nourishment (plants are ALIVE, people!), and we must all imbibe water to survive. These, and many others, are universals of the physical, of the traits we all share as humans.  It is easy for anyone to accept these are universal to all human societies.  Apart from these basic things, there are universals that are more abstract.  For example, all humans dream, therefore all human cultures assign some sort of meaning to dreams.  For the most part, every single culture of the world has a taboo on incest.  Even in places like pharaonic Egypt, or in Medieval Europe, where the very top of the society would often marry their siblings, this was not done for sexual or reproductive reasons.  Marrying your sister meant that she would not marry someone from another family, which meant your family’s personal power and wealth would not be diluted.  This was the main reason rulers of Egypt and Europe married siblings.  It helped consolidate power, something the “elites” are always deeply concerned about.  And, yes, the populace found it as gross as we do today.

There are so many other human universals to be studied that it enrages me how ignorant and stuck to their assumptions anthropologists and other such scientists have been, stating with certainty that very few human universals exist.  Sticking to a flawed idea, in the face of overwhelming evidence, is the quickest way to ensure worthless science.  One of the interesting universals that has been found regards poetry.  Every single culture on Earth has had poetry of some sort, but the universality goes deeper than that.  Nearly every culture’s poetry consists of lines lasting three seconds in time.  This may seem arbitrary and weird, but for tens of thousands, if not hundreds of thousands of years, humanity carried its history and stories in our minds and transmitted them orally.  The three second line structure facilitates memorization, for the repetition creates a temporal framework in the mind, allowing for epic poems to be recited and recalled.  Recall how Aristotle railed against teaching people to write because he felt it would dilute their minds and weaken their memorization skills.  (He may have been right. Ha!)

Another human universal is the need for a spiritual connection with the world around us.  This does not mean organized religion, a specific trait of advanced cultures that seek to dominate the collective spiritual thought of the people through dogma and coercion, but instead refers to the inner individual need to attain closeness with Mother Nature, a divinity, or just the soul of the universe.  Even the simplest tribal societies had deep spiritual thoughts, and means by which to enhance and appreciate these experiences.

            Anthropology in the Western world spent way too many decades navel gazing and attempting to study every part of the Earth strictly through the lens of white, European, monotheistic cultures.  They did a great disservice to humanity in doing so, bringing about such stupidity that whole nations used their flawed “science” to justify genocide, imperialism, and the extermination of “undesirable” cultures.  The cost of this stupidity is still being paid.  Genetically, the difference between any two humans, no matter how remote or different they may seem, is miniscule.  It is literally 0.1%.  99.9% of your DNA is exactly the same as Napoleon, Bette Davis, or the ancient poet Rumi.  We are more alike as Homo Sapiens Sapiens than we all care to admit, and until we all choose to see ourselves this way, we will continue to breed hate, animosity, and jingoism in our people.  Donald E. Brown wrote this work in the early 1990’s, and I hope that it leads to a better understanding of the issues and limits inherent in the field of anthropology, especially when it comes to the biases and mental limitations of those doing the research.  While this was a difficult book to read, both due to the subject matter and my rage at anthropologist’s stupidity, I found it inspiring and educational.  I highly recommend it for anyone interested in the technical aspects of studying humanity, and the many properties and traits we all share universally.

Don S. Lemons Describes the Importance of Drawing in the Discovery of New Scientific Concepts

 

Drawing Physics: 2,600 Years of Discovery from Thales to Higgs – Don S. Lemons (2017)

 

            Small books are joyful books!  While I adore an imposingly thick reference work, dense and packed with information, I find great joy in the relatively small, concise, and engrossing books such as Drawing Physics, by Don S. Lemons.  The trick to these books is that they must be hyper-specific, or else the thread is lost and the writer loses focus.  Don S. Lemons cleverly designed this book to move forward, not only chronologically, but in the levels of scientific complexity.  The overarching idea explores the invaluable use of drawn imagery by scientists to either describe a previously unknown property of our universe, or to create a visual symbol of the scientific experiment or idea being described.  It is very clever, and builds upon itself, helping guide the reader through topics and ideas in the world of physics as they were developed and theorized, from antiquity to the modern day.

            If any book could claim to embody the old dictum, “a picture is worth a thousand words,” it is this one.  The simple drawings lead to very complex ideas.  Lemons succinctly describes each individual scientist’s life, and their educational and cultural backgrounds, providing a foundation for the amazing discoveries discussed in each chapter.  It is still eye-opening to understand how much our human ancestors managed to deduce and intuit, using just the observed details of the world around them.  We humans are a magnificent thinking creature.  Our ability to think is only rivaled by our ability to share our thoughts and conclusions.

            Whereas previously, humans only shared their knowledge orally, forcing students to memorize whole epic poems and philosophical treatises on nature, the advent of writing allowed humanity to pass on knowledge across time and distance.  The combination of drawn images and the written word?  It is likely the single greatest synthesis in human existence.  Much like the “thought experiments” used by scientists to imagine situations which are difficult to describe in words alone, the drawings in this book allow the reader to create a mental image, helping one understand the deeper meaning behind the formulas and theories described within.  Sometimes an image can provide an example of an inalienable truth of our universe, even though there are not yet words to describe the actual internal workings. 

            That is the beauty in art.  It provides communication between minds in an instant manner.  Even a simple doodle can express ideas so vast and complex that people could not understand them without the imagery.  Art also communicates across language barriers.  A beautiful painting or sculpture can be appreciated without language.  A diagram of a triangle, its angles, and the relationship between them, conveys knowledge across the centuries, much like Pythagoras and the theorem named after him.  Don S. Lemons has put together an amazing little book, valuable to anyone interested in the progress of scientific thought, and in the creative ways which scientists portray their discoveries.  I felt inspired and uplifted, in awe of the creativity and intellect of my fellow human beings.  Highly recommended.

Carlo Rovelli Shares the Wonder and Beauty of Quantum Theory

 Helgoland: Making Sense of the Quantum Revolution – Carlo Rovelli (2021)

            One of the greatest compliments I can give the eminent physicist and author Carlo Rovelli is that his informative and entertaining science books rival Richard Feynman’s for the sheer joy they give me upon reading.  I have reviewed three of Mr. Rovelli’s amazing books on RXTT’s Book Journey, White Holes, Reality Is Not What It Seems, and The First Scientist: Anaximander and His Legacy.  Each one is incredibly eye-opening, and written in a manner so casual as to seem like personal conversations between Mr. Rovelli and I.  This latest work, an exploration into the ideas of quantum mechanics and their repercussions and implications, is critical reading for me, and has given me much to think about.

            Rovelli understands that us lay readers, people with an interest in physics but not professional scientists, can experience the same awe, the same thrill of understanding, that the researchers and theoreticians feel when they gain new knowledge.  The difference lies in the presentation of the material.  Since quantum mechanics is an intensely odd, yet deeply relevant field of modern science, it takes a special storyteller to relate the discovery, formulation, and utilization of this particularly intriguing area of current scientific thought.

            The author never loses sight of the humanity involved in science, and of the amazing achievements and knowledge that mere humans can bring to the world at large.  The recounting of the early 1900’s, a time when the formal, mechanistic, classical physics of Newton were upended by Einstein’s relativity, Heisenberg’s uncertainty principle, and Planck’s exploration into the world of quanta.  These world-shaking ideas took hold in the minds of young physicists, producing one of the most successful, and rigorous understandings of the natural world that humanity has ever encountered, quantum theory.  Nearly every new development in our world over the past 100 years owes everything to our knowledge of the quantum nature of reality and the ability of our fellow humans to create technology dependent on the quantum world.  Sadly, most of us benefit from these ideas without understanding even the smallest part.

            Besides sharing the story of quantum theory’s discovery, the author explores how the theory refutes many of the long-standing assumptions held by the great thinkers of humanity.  It is this aspect of quantum theory that has yet to see its full flowering.  Most of us walk around with our grammar school science knowledge informing our view of the world, when, in fact, that model of the universe is flawed and incomplete.  Quantum theory instead describes a universe where the divisions between objects disappear, where the observer cannot be removed from what is observed, where absolute certainty about anything is a mirage.  It will take centuries for humanity to fully grasp these ideas and drop the old prejudices.

            Rovelli also makes it abundantly clear that, for even the most highly trained minds, the ability to use quantum theory is not the same as the ability to fully comprehend quantum theory.  He is honestly forthright when describing his own attempts, mostly unsuccessful, to cognitively grasp the deep truths that quantum theory seems to tell us about the reality we live in.  Thank Mario that humanity has minds such as Mr. Rovelli’s whose curiosity leads them to seek and grapple with the most obtuse and rarefied ideas, in order to help the rest of us understand what makes up the world we all share.  As with all of Carlo Rovelli’s books, it is highly recommended.

Lawrence M. Krauss Shares How Far We Have Come, and How Much Further We Have To Go

 

The Known Unknowns: The Unsolved Mysteries of the Cosmos – Lawrence M. Krauss (2023)

 

            If I could define myself with just one word, it would be “reader.”  Everything in my life either stems from, or draws from, the many books I have read in my 49+ years on this planet Earth.  My biggest heroes, Kurt Vonnegut, Robert Anton Wilson, Richard P. Feynman, etc., came into my life through the written page.  When I began RXTT’s Book Journey almost ten years ago, I dreamed of the possibility that book publishers and authors would appreciate my reviews and want to share their soon-to-be-released work with me.  Dreams do come true.

            The latest advance copy received by the RXTT household is physicist Lawrence M. Krauss’ forthcoming book, The Known Unknowns. (That is the UK title.  The book will be titled The Edge of Knowledge in the USA, probably because Donald Rumsfeld’s use of the phrase “known unknowns” became such a joke in ignorant America.)  After requesting it from Mr. Krauss himself, he contacted his publisher on my behalf and I was sent the book.  MIND BLOWN.

            The reason I read is to enlighten myself, both with new ideas and new information, for I am a curious mind.  Sometimes, the most useful and valuable books are not the ones with the most data, but instead the books with the best questions.  One such book, among many faves, is Richard Feynman’s The Character of Physical Law, a book full of ideas and questions which, it turns out, was also a guiding light for Lawrence M. Krauss.  Feynman’s spirit, willing to share ideas in a thoughtful manner, directly engaged with the toughest questions, and able to explain the most obtuse scientific thought in a manner where a layperson can grasp the fundamentals, is alive and well in Mr. Krauss.  We are all very fortunate.

            Krauss divides this book into five chapters, each one concerning itself with a specific topic where science has shed some light, but where there are still far more questions than answers.  Time, Space, Matter, Life, and Consciousness are the guideposts for Lawrence M. Krauss to not only sum up our current knowledge, but to also point out the vast gaps.  Our collective ignorance is the greatest impetus towards science, scientific discovery, and new knowledge.  The very worst of humanity arises when humans feel absolute certainty, whether political, religious, or social.  Not knowing is the greatest gift to an inquisitive mind.

            My biggest surprise as I devoured this book was its readability.  There are many amazing minds in the world of science, and physics specifically, but very few have the ability to provide us their thoughts and knowledge in such a fun and engrossing manner.  Some books, even great ones, can be a chore to read.  Lawrence M. Krauss has succeeded in creating a book that will enlighten young and old alike, while also opening up their minds to the myriad possibilities yet available for exploration and research.  This may be this book’s most valuable contribution, sparking the mind of some young students out there, and starting their paths toward new discoveries, new fields of research, and, hopefully, new questions.  Questions are truly important.  Anyone claiming to have all the answers is trying to rip you off, and should be treated accordingly.

            Each chapter begins with questions.  For example, the chapter titled Matter starts with these:

What is the World Made of?

How Many Forces are there? 

Is Anything Fundamental?

Is Quantum Mechanics True? 

Will Physics Have an End?

Will Matter End?

Krauss perfectly encapsulates our current state of knowledge in each chapter, sharing it with the reader through the specific details of past scientific achievement.  He then explores how we came to find that knowledge, use it, and seek to understand the underlying principles involved.  One of the best attributes of scientists is their humility in the face of new data.  It allows for self-correction, which is why the scientific method has been such a valuable tool for humanity.  Krauss details the baby steps taken in our human search for knowledge, steps often met with wildly erroneous interpretations, each of them critical points in our collective knowledge.

            Krauss brings his physics knowledge to bear on what is the most complex and mysterious part of our everyday world, the quantum realm.  He guides the reader through the many different steps us humans required to comprehend that the sub-atomic world even existed, and details plainly why it remains such a difficult science to explain.  Everything in our modern world is touched by subatomic processes, from the manufacture of medicine, to the Global Positioning Satellite System, to the various smart phones and gadgets we all take for granted.  None would work without our collective understanding of the processes involved in the quantum realm.  The irony remains that, even as we use quantum science to create new wonders, we still do not fully grasp exactly what processes allow for these modern marvels to function.  We are much like the ancient humans who used fire to bake clay, cook food, warm their home, and provide light, but had no clue as to what caused the fire to exist in the first place.  We now know that free oxygen atoms in our atmosphere combine with the carbon in wood, and that this reaction creates new compounds (Carbon dioxide, water vapor) and energy (light, heat).  It seems common sense to us now, but to a human living 500 years ago this would be utter nonsense.  They “knew” that fire was but one of the four basic constituents of everything that exists, along with Water, Earth, and Air.  For centuries, this basic explanation served its purpose, but it did not actually provide verifiable, repeatable truth.  Only the scientific method does that.

            I hope that this book receives a very wide readership, for it is as equally valuable to a young scientist as it is to a layperson interested in big ideas.  Our world bounces back and forth from close-minded totalitarian fundamentalism to wide-open progressive ideals.  It is very easy for a society to lose ground, to lose hard-earned knowledge and wisdom, because someone, or something, claims to know all the answers.  Beware of anyone telling you to stop asking questions.  RUN AWAY from anyone telling there are no new answers out there and we already know all we need to know.  They are Liars and con-artists and only seek to control you so they can line their pockets.  Find those among us who are kind, who seek new answers and new questions, who understand that, for all we know as humans, our knowledge is dwarfed by the vast amounts we do not know.  Lawrence M. Krauss has crafted an amazing book, one that not only tells us what we know and how, but informs us of what we have yet to find out.  I highly recommend it.

Heredity, and genetic science, are more complex than one could ever imagine

She Has Her Mother’s Laugh: The Powers. Perversions, and Potential of Heredity – Carl Zimmer (2018)

            (A quick note on some awesomeness that has graced this humble book review blog recently.  Several weeks ago I received notice that RXTT’s Intellectual Journey has been included in Feedspot’s Top 200 Book Blogs, currently found at #193! Amazing!  Many thanks to blog master Mr. Anuj Agarwal, and the good people at Feedspot.  BOOKS RULE!)

The past decade has seen the world of genetic research explode, in both the amount and the scope of what is being attempted.  Researches the world over have new tools with which to explore the genetic codes that provide the instructions to make all parts of living organisms.  As with all emerging scientific fields, the general public’s discourse is decades behind the forefront of research.  This leads to reactionary angers, manipulation of the ignorant through fear, and an inability to properly fund cutting edge research.  Carl Zimmer has done an amazing job corralling the wild and weird history of the human study of heredity and genetics, and made it truly enjoyable to read.

Humans have been genetically altering the natural world around us for millennia; way before we knew what drove heredity, or had any idea about why offspring acquired certain characteristics of their parents and lost others.  These early genetic experimenters were the early humans that began to cultivate wild plants.  An example of this is the modern tomato.  The original fruit, which is exceedingly rare to find these days, was basically a tiny, tart and seedy berry.  The humans in the New World (many of our modern foods were not found in Eurasia, Africa, or Australia) would choose a plant with slightly lager or sweeter berry, collect those seeds, and propagate it.  Each new generation, the human would choose the plants with the best fruit, propagate that one, and dispose of the lesser plants.  Over the centuries, that basic method created whole new species of tomato plants, capable of producing much bigger, sweeter, and more nutritious food.  The same process allowed our New World ancestors to create what we now call corn, chili peppers, potatoes, and a host of other vegetables that are ubiquitous in modern diets worldwide.  This same process was undergone by early humans domesticating cattle, goats, swine, etc.  By breeding only the animals whose traits were preferred, more animals capable of reproducing those traits existed, soon making them the norm.

In spite of the long history of humans altering the plants and animals around us, it seems that as a species, we humans have an extremely short memory of our collective past.  We allow ideas that have no relation to the world around us to color how we see the world itself.  One of the biggest restraints to developing the science of heredity and genetics came from organized religion, and the blind obedience that their dogma requires of their followers.  Ideas that are in opposition to religious dogma are disposed of without exploration, and people are kept blind, ignorant and happy in their stupidity.  For centuries, the idea that the world was truly static, truly unchanging, was prevalent in Western culture.  This stems solely from theologians and priests demanding that everyone see their little collection of stories, history, genealogy, myths, and fables as LITERAL TRUTH, never to be questioned, never to be doubted.  In this world view, every animal species was perfectly crafted by an omniscient creator, and these species have remained unchanged since the beginning of time.  This belief depended on the unchallenged assumption that the world was just over 6,000 years old, an assumption so stupid and wrong yet strictly dogmatic, that it was unchallenged for centuries, even causing the execution of people willing to claim otherwise.

It is quite fitting that despite these idiocies pushed on people by organized religions, it was ordained members of the clergy who did the most groundbreaking work on genetics.  Gregor Mendel, an Augustinian friar and abbot, decided he was going to do his own experiments, regardless of the consequences.  He used the common pea plant, and its many colorful flowers, as his subject.  By cross-breeding them over and over, and carefully observing the results, he developed the idea that the outcome of reproduction is due to the offspring inheriting some sort of instructions from both of its progenitors.  He showed how, for these plants, and it turns out, for much of life on Earth, there is a rigid set of probability controlling which traits are passed on and in what quantity.  By selectively breeding only tall plants, an d then pollinating them with pollen from short plants, he was able to show the existence of dominant, and recessive, traits.

Dominant traits are those that will appear in an offspring if only one of its parents carries that trait.  Recessive traits can spring up in offspring, but only if both parents carry the recessive trait themselves.  He also determined the ratio in which these traits would appear, and was vindicated by his experiments.  People condemned the man, ignoring his work. It was only after his death that recognition came, and now Mendel is considered the father of genetics for his efforts.

Breeders and scientists continued working in this manner for centuries, through trial and error, until a great discovery was made.  This was the discovery of the DNA molecule, and how it is found in every single form of life on the planet, from bacteria to trees to humans.  Understanding that this complex and huge molecule encoded instructions for the creation of all parts of an organism was something that, even today, many people are not willing to accept.  Once this was found out, scientists and researchers sought to decode what was now called a genome.  Some animals have few chromosomes containing DNA, and others have dozens and dozens.  Each species is different, yet each species carries so much “junk” DNA (DNA that is left over from previous ancestors or organisms) that looking for the genes that are actually shaping our bodies was a herculean task.  Over the past 30 years much groundbreaking work has been done in studying genes, what they are responsible for, how to alter them, and how to use gene therapy to help people suffering from genetic diseases.

Another awesome part of this book discusses the study of heredity, as it relates to what traits and genes are passed on to our children.  Humans are pretty selfish and stupid, for the most part, and because of this many people were convinced that having “bad” parents automatically created “bad” offspring.  This was such a racist and classicist idea, yet it persisted for a long time, because, of course, most “educated” people canme from the rich white upper crust of society.  It allowed people to classify a pecking order of human quality, with white Europeans on top of the list, and African and tribal people at the bottom.  These morons made the grievous mistake of assuming that genetics count for everything in a person’s makeup, and that environment, opportunity, and nutrition had no bearing.  These idiots fought the hardest, and still fight today, to try and maintain the status quo which keeps them fat and happy while everyone else deserves their shit lot in life.  It has been shown, countless times, that human achievement and quality is an ongoing process, and results from everything that shapes a person, from their family life, to their education, to their nutrition, to where they are born.

Even after these dumb-ass ideas were discounted, people continued to stick to strict ideas of heredity, ideas which have no bearing in the real world.  In one example, around the 1920’s, the comedian Charlie Chaplin was sued by a young lady claiming her son was his illegitimate child.  Chaplin sought to have the court accept scientific evidence (blood type) that the child could not be Chaplin’s, but at the time the courts were scientifically ignorant, and would not allow it.  In recent decades, this mindset has flipped, and in most courts, only DNA evidence is accepted and it is seen as irrefutable. The blind stupidity of this is pointed out by the case of a woman with three children, who, in a custody battle, had blood work done.  The blood work showed that her kids did not share her DNA, so the courts accused her of stealing the babies when they were young.  She tried everything, including testimony from the doctor that delivered her babies, but had no luck.  It was not until several scientists did extensive work on the lady that it was discovered that she is a chimera.  Her body is composed of two distinctly different sets of DNA.  Her blood contained DNA that did not match her kids, but her muscle and skin contained matching DNA.  Genetic chimeras are quite common, in fact, it is estimated that most humans are genetic chimeras on some level.  Some of them are formed when two eggs are fertilized by two sperm I the uterus, and then these two combine into one embryo, creating one human.  Sometimes these come out hermaphroditic, other times it is seemingly undetectable.  Even other people have stripes across their skin, from two separate genetic pools. 

One other seeming insanity I came across while reading this book is the discovery that human mothers exchange DNA with their offspring, and vice versa.  It used to be thought that the placenta was a protective barrier, keeping the fetus separate, but that is not the case.  The mother’s DNA does enter the child, and sometimes the child’s DNA goes back through the umbilical cord in the form of stem cells and become part of the mother’s body.  In some cases it was found that the fetus’ stem cells became neurons in the brain of the mother, sometimes months after the child had been born.  The implications are awesome.

I could write about the amazing stuff in this book forever.  I think it is a very engaging read, and worth the time it takes, for anyone interested in heredity, genetics, science history, and the foolishness of man’s assumptions about our own nature.  Highly Recommended.

Quantum Gravity, and the history of human exploration into the nature of our Universe

Reality is Not What It Seems: The Journey Into Quantum Gravity – Carlo Rovelli (2014)

            Around a year ago I read and reviewed another book by the Italian physicist Carlo Rovelli.  (Click Here for that Review) That book was a detailed history of the man known as Anaximander, of whom I wrote that he is “the earliest human that we have record of who helped create the logical and rational framework that set the stage for the scientific revolution all humans have experienced over the past 250 years.”  At the time I bemoaned my inability to read his then-current book Reality is Not What It Seems.  Thank goodness for the good folks at the M.D. Anderson Library of the University of Houston.  They acquired the English translation and this is what I managed to stumble across during my browsing.

            Where to start?  This book is an attempt by Mr. Rovelli to discuss the history of our collective efforts to understand what constitutes the fabric of Reality, the elementary nature of our selves and everything that exists.  Beginning with Anaximander, Plato, and Aristotle, Mr. Rovelli describes how each of these ancient geniuses grappled with the substance of reality, and with the ability and limits of the human to comprehend this reality.  He details the amazing and near-miraculous insights from these men that propelled our entire world forward in the quest to understand. Leuccipus and Democritus formed the basis of “atomist” theory, purely through rigorous analytical thought, understanding that all matter is composed of small indivisible parts. Democritus alone was such an amazing thinker.  It is a shame most of his massive output has been lost to history.

            After the initial period of discovery, once monotheistic religions took over the human landscape, progress was effectively halted, and the knowledge of our forefathers was lost in the Western World.  Scientific fact was replaced by dogma and blind faith in the make-believe magic stories of priests and the governments which aligned themselves with religions.  It was after nearly a thousand years of barbaric ignorance that travelers and scholars visited India and brought back the wisdom of the ancient Greeks, knowledge which was critical to creating the modern world we all share.  From this influx of ancient wisdom and science, someone like Isaac Newton was able to understand and explain what he saw as the structure of the Universe.  Newton saw a fiercely deterministic static Universe.  His laws of motion and his invention of the Calculus allowed humans to plot star and planet trajectories centuries in advance, and his mathematics and science helped the Western world shake free of its religion-induced intellectual coma.

            The world as Newton saw it was un-changing, and infinite.  Scientists continued to study the Universe, finding and creating new tools with which to explore.  In the early 1900’s, Albert Einstein proceeded to shake the world to its core, much like Newton had done before.  Einstein understood that there is no static Universe and that everything is constantly in motion relative to everything else.  He was the first human to grasp that time is not a specific thing, existing separate from the Universe.  He saw that we live in an ever-expanding Present.  Einstein also saw that the world is not what Newton stated.  There is no matter and energy floating in empty space.  There is just matter and energy existing in space-time and gravity is merely the deformation of this space-time by massive objects.  All of these things have been verified countless times.

            What Einstein did for the world at large, quantum mechanics did for the world of the very small.  It is an extremely successful theory and its predictions have been validated countless times as well.  Quantum Mechanics shows us that the world is made up of quantum objects, which have probabilistic traits.  One cannot know everything about a proton, unlike in Newton’s time, when it was assumed that this was possible.  This indeterminacy has been proven to exist throughout the Universe at all quantum levels.

            All of this leads into the discussion of Quantum Gravity.  Einstein’s Relativity and quantum Mechanics work together in most ways, but in special cases, such as black holes, or singularities, both theories fall apart.  Gravity can only be calculated in the macro sense, and quantum effects never give definite answers.  To combine these two theories is the current goal of theoretical physicists around the world.  Some have been working on String Theory, which predicts the existence of super-symmetric particles.  These particles have not been seen in experiments at particle colliders.  This lends more weight to Rovelli’s field, which is studying Loop Quantum Gravity, which seeks to study the constituents of gravity, or the quanta of gravity. 

            Light acts as a wave and a particle.  The quanta of light is the Photon.  Gravity seems to act as both a wave and a particle, gravitational waves having been detected as recently as 2016.  Loop Quantum Gravity postulates that the smallest quanta of gravity are actually small closed “loops” as opposed to points.  He goes into a great explanation of his research and of the ways that scientists have arrived at this idea, one which seems to be more promising that String Theory. What a great book.  The Bibliography at the back will keep me happy for a while too.  I wish I could better describe how much is contained within this awesome book,  but you will have to read it for yourself.
