You might think that this book has received four stars but if you know anything about uantum theory you will be aware that a uantum object can be in a superposition of states And this uantum book is in a superposed state of 5 stars for the subject which is fascinating and important and 3 stars for the writing which is disappointingly poor iven Jim Al Khalili s expertise and experienceIt might seem that the whole concept of uantum biology is a truism that hardly needs exploring When every chemical reaction or electrical activity in a living organism is base McFadden and Al Khalili explore the role of uantum mechanics in living organisms This new field of uantum biology is finding that life lies on the edge between classical and uantum physics thus the title of the book The authors do not believe in any spiritual or mystical influences rather they dig deeply into biochemistry They identify specific situations in which the uantum properties of electrons and protons influence organic processes McFadden and Al Khalili explain without math the relevant attributes of the uantum world wave particle duality uantum tunneling superposition and entanglement They begin each case with a story and then delve into the chemistry and physics behind it How does the European robin find its way each year from Scandinavia to the Mediterranean and back How does the Monarch butterfly make its way across North America to its winter hideout in the mountains of Mexico Monarchs and the European robin have the protein cryptochrome enabling them to navigate using the earth s magnetic field I was struck by the fact that the monarchs that return every summer are the randchildren of those that left The monarchs breed in route and their progeny continue the journey somehow knowing the way The authors note that many animals plants and even microbes use cryptochrome for magnetic field detection Cryptochrome contains free radicals molecules with an unpaired electron in the outer shell Particles in cryptochrome molecules can align their spin to the earth s magnetic field allowing the robins and monarchs to detect the way towards or away from the euator McFadden and Al Kahlili explain the uantum property of spin to help us understand how cryptochrome works It s counterintuitive uantum spin is not like anything we are familiar with in the macro world A particle s spin can be one direction or the other up or down or it can spin in both directions at the same time superposition Pairs of electrons forming chemical bonds become entangled so that when one changes its spin state so does the other Until measured both electrons are in superposition spinning both up and down at the same time When either one is measured both change to a single spin direction instantaneously Fascinatingly the spin of entangled particles stay coordinated even after the bond is broken and they are separated by large distances The author s explain how changes to the uantum state of spin signal to the organism the orientation of

magnetic field s complicated The book provides the detailsMcFadden and Al Khalili organism the orientation of the magnetic field It s complicated The book provides the detailsMcFadden and Al Khalili the amazing complexity of life with the example of the single cell In the emerging field of synthetic biology when scientists create an amino acid or sugar they create one product at a time The authors o on This is not an easy task and reuires careful control of many different conditions inside customized flasks condensers separation columns filtration devices and other elaborate chemical apparatusesYet every cell in your body is continually synthesizing thousands of distinct biochemicals within a reaction chamber filled with just a few millionths of a microliter of fluid How do all those diverse reactions proceed concurrently And how is all this molecular action orchestrated within a microscopic cell This is a profound mysteryAmong the many important substances cells manufacture are enzymes These are protein catalysts that speed the cell s many chemical reactions For example collagenase is essential to deconstruct unneeded or damaged collagen and construct new collagen It performs its operations in nanoseconds with stunning efficiency Good to know since collagen holds our trillions of cells together Collagenase strategically places a positively charged zinc atom and a negatively charged oxygen atom to break exiting chemical bonds and form new ones But is electrical charge the only force this nanomachine uses The authors hold that uantum tunneling is also used to move electrons into position In their uantum state electrons are both particles and waves and their wave function ives them a probability of being found on the other side of a chemical barrier perhaps electric charge or just empty space The authors also hold that uantum tunneling is also used in cellular respiration an extremely complex process cells use to derive energy from food Whether life evolved to use uantum tunneling or it just was a lucky addition is debated The authors explore the details of uantum mechanics reviewing in detail the double slit experiments that show wave particle duality They also explain coherence the state in which particles maintain their uantum nature Decoherence is the state in which particles operate in a classical manner Until observed particles in the double slit experiment have coherence and take all possible routes to their destination Observation causes decoherence in the double slit experiment and one route only is taken The bustling movement of neighboring particles can also cause decoherence Thus the particles that make up living things which are densely packed have been assumed to operate as classical particles not uantum ones The author. Life is the most extraordinary phenomenon in the known universe; but how did it come to be Even in an age of cloning and artificial biology the remarkable truth remains nobody has ever made anything living entirely out of dead material Life remains the only way to make life Are we still missing a vital ingredient in its creation      Like Richard Dawkins' The Selfish Gene which provided a new perspective on how evolution works Life on the Edge alters our understanding of our world's fundamental dynamics Bringi.

Johnjoe McFadden Û 2 Review

He slightly difficult science magazines and articles The material is made simple as possible but it is not dumbed down I really appreciate well written books about science when they are written by active researchers in the field And this book ualifies as McFadden is a research biologist and Al Khalili is a What lies beyond the molecular level Where we can not see Please note that I put the original German text at the end of this review Just if you might be interestedThe motor of life seems to be complicated than expected It turns out and than the previous research has observed rather only individual components of the complex machinery One or the other connection was made and a few processes were followed Only nobody knows what underlies these processes on deeper levels For example breathing heredity photosynthesis the electrical uantum activity of neurons magnetoreception consciousness sense of smell and the origin of life Moreover these are just the processes that this very young science discipline has been able to investigate so farMany observed phenomena imply levels than postulated by established research uantum field theory opens a few doors concerning this Which of the thought experiments fits the inexplicable observed anomalies will become apparent The fact that the hostly long distance effect cannot be forced well to manifest complicates the research When nervous particles are nowhere and at two places at the same time at the same time This alone contradicts both our fundamental ideas of physics and our worldview Because it fits into the realm of myths legends and fantasy rather than serious science Also if that limit falls what is impossible What is eccentricity close to madness and what is the realityA few hypotheses can be set upThere are overlooked factors in the known three dimensions that are so tiny or so small in effect that they have not been considered beforeMore dimensions than expected From the 4th and other dimensions come interactions that allow metabolic processes photosynthesis and life in our dimension Without this connection life would not be possible Suppose that life would disappear in our dimension or another dimension Would that also destroy life in the connected dimension because the two are dependent on each otherParallel universes A parallel universe interacts with the other An unknown kind of entropy shapes the laws of nature Different variants of the principles of thermodynamics and ravitation interact between the worlds Or several parallel universes with several types of natural laws are in complex interaction For a multiverse the possibilities of variation would be infiniteSimulation Hypothesis If the uanta are some programming language the world would be made up of code Alternatively the uanta are just the coarsest fundamental building blocks under which the actual code is hidden Mistakes in programming would explain anoma I have a problem with most of the new science books that I ve been reading lately They really aren t saying anything new and when they do they seem to enter into woo woo land The authors demonstrate nicely how certain biolo absolutely stunning a book that with often beautiful prose describes key concepts of uantum physics and uantum biology in a way that is detailed and not oversimplified but still able to be understood by a layperson such as myself who doesn t even have an A level in physics a fascinating exploration of what is potentially the most exciting roundbreaking field of science presently 35In eneral I love reading about the smallest processes in biology or physics I could read an entire book on the inner life of the mitochondria s electron transport chain and I would be enthralled read an entire book on the inner life of the mitochondria s electron transport chain and I would be enthralled find it find it exciting when authors want to understand the most in depth mechanisms at work in a each system I love it even if the authors take the knowledge they uncover and attempt to apply it to big systems such as networks systems biology etc The authors of tis book tried to do just that I am not exactly sure why I didn t love this book Perhaps despite my constant critiues of books that are promoting sexy science at the expense of providing a realistic understanding of the subject at hand I wanted sexy science from this book At times even though it examined each Phenomenon In Great Detail in reat detail felt disjointed I understand the overall theme but perhaps I needed hand holding Even though I was interested in each subject present I am especially interested in how particles spin sync and enter phase transition the books didn t feel that new or exciting It could be that I have read too many books that have provided some of the same material Regardless of my criticisms I think the work being done in uantum biology is important Particularly important is the focus on explaining how the same forces at work in physics are also at work in biological systems I like the uestions the authors raised Certainly work needs to be done to understand how action potentials lead to consciousness Once that is established there is work still to be done in understanding the uantum nature of action potentials The discussion on the hard problem of consciousness was by far my least favorite part of the book I enjoy reading Andy Clark and the Churchlands take on consciousness but cannot waste one minute of life justifying Chalmers unscientific discussions on the subject Even though these authors were arguing against the type of position Chalmers provides his readers they went too far in validating it Overall though it is Gone: The Disappearance of Claudia Lawrence and Her Father's Desperate Search for the Truth great that researchers are attempting to investigate and write about uantum bio If you are unfamiliar with the field but are curious it s worth the rea. Mselves with such precision Life on the Edge accessibly reveals how uantum mechanics can answer these probing uestions of the universe Guiding the reader through the rapidly unfolding discoveries of the last few years Al Khalili and McFadden communicate the excitement of the explosive new field of uantum biology and its potentially revolutionary applications while offering insights into the biggest puzzle of all what is life As they brilliantly demonstrate in theseroundbreaking pages life exists on the uantum ed. S then review experiments that show examples of coherence most notably in photosynthesis in bacteria They believe that in photosynthesis some particles are actually operating as uantum computers exploring all possible paths at once to route electrons the uickest way to their destination Again the book provides the details McFadden and Al Khalili look into the sense of smell The prevailing theory is that the olfactory receptors recognize molecules of certain shapes working like a lock and key When there is a fit the receptors signal the brain However the authors think is involved They believe the vibrational freuency in the atomic bonds of molecules distinguish what we smell Both the shape theory and the uantum level theory which may involve uantum tunneling have had holes punched in them The latest seems to be that both processes are at work Detailed explanations are in the bookThe authors explore whether uantum effects are involved DNA mutations They note the weak hydrogen bonds between base pairs of the nucleotides that make up DNA The hydrogen ion is a shared proton that normally lies closer to one of the nucleotides but rarely it moves to the other side Is this due to uantum tunneling McFadden and Al Khalili consider uantum tunneling in enzymes to be proven so why could it not also take place in DNA Could this be one cause of mutations that lead to evolutionary change The authors don t claim to have a definitive answer but clearly are intrigued by the possibility Consciousness has received a lot of attention as subject to uantum influences The authors examine a couple of specific processes but eschew telepathy and other paranormal theories The rapid firing of neurons underlies body movement and consciousness McFadden and Al Khalili look at potassium ions that move through ion channels in neuronal cell membranes at the fantastic rate of one hundred million per second They wonder whether these ions may be in coherent states with wave like properties that would foster their reat speed They also consider the idea that the electromagnetic field created by all the brain s neuronal activity in turn synchronizes neuronal firing which is indicative of consciousness While they are very interested in new research on these ideas they don t reach a conclusion as to their validity The authors end by speculating about possible uantum influences in the origin of life and even how it may be applied in the creation of synthetic life There is a fair amount of speculation throughout the book but some of their assertions seem well supported and accepted They provide very detailed explanations for their positions and cite supporting experiments and concurrence by other scientists At a minimum McFadden and Al Khalili make the case for expanded research in this emerging area of study This would hardly be the first time that scientific proposals once dismissed as too far out turned out to be true For a long time it was believed that scientists could only study uantum mechanics at absolute zero in their labs Yet in recent years excellent evidence of uantum mechanics at work in humans birds plants and other living things has come to the fore Who knew This Book Is A book is a and very accessible introduction for the eneral reader It uses virtually no math Rather the writers possess a neat Moonrise (Snowfall, gift for metaphor Stephen Jay Gould had thisift too and while Life on the Edge isn t SJG that paragon of science writing it does the job and does it well I absolutely loved this book The subject is fascinating and it s written in an easy to read style that is very layman friendly There s a sprinkling of humour and the prose even borders on the poetic in placesThe examples the authors choose to illustrate the concepts they are trying to teach are excellently chosen and really held my attention I recommend this book to anybody with an interest in this seriously engaging subject Spooky action at a distance still does my head in though A wonderful book describing wonderful thingsScience is not my strongest area in learning but this book makes clear an opaue to me part of physics which usually is understood through mathematics and specialized scientific euipment able to view or measure particles of atoms As a book written for the eneral reader it does not have a lot of math and it includes drawings which add clarity to the subject addressed in each chapter The chapters each cover a single main subject which illuminates how plant and animal molecular biology has been discovered performing vital life sustaining functions with uantum physics Each chapter builds on the previous information described earlier in the book which allowed this reader to keep up But I recommend a consistent progression revisiting the book every day to read a chapter if you are not a science eek If the book is picked up days later from the #last time one may have read it the # time one may have read it the might need to start over re reading again earlier chaptersI was astounded that the authors were able to describe such subjects as uantum photosynthesis and the electrical uantum activity of neurons in such a clear yet simple manner that someone not very scientific can understand these important new discoveries The last chapters are speculative but never irrationally so Instead I am as excited as the authors are to see if future uantum biology research will uncover about why we are alive and why rocks are not These discoveries are new to me because I raduated from college several decades ago I am very excited about being able to understand the uantum world a touch better Through The Examples Given In Each ChapterI the examples iven in each chapterI The Coming Age of uantum Biology to those familiar with Ng together first hand experience at the cutting edge of science with unparalleled ifts of explanation Jim Al Khalili and Johnjoe Macfadden reveal that missing ingredient to be uantum mechanics; the phenomena that lie at the heart of this most mysterious of sciences Drawing on recent round breaking experiments around the world each chapter in Life on the Edge engages by illustrating one of life's puzzles How do migrating birds know where to Mastering the Art of Saying No Without Feeling Guilty: Tips, Techniques and Strategies go How do we really smell the scent of a rose How do ourenes copy the. ,
