Lifes Ratchet



The Cells In Our Bodies Consist Of Molecules, Made Up Of The Same Carbon, Oxygen, And Hydrogen Atoms Found In Air And Rocks But Molecules, Such As Water And Sugar, Are Not Alive So How Do Our Cells Assemblies Of Otherwise Dead Molecules Come To Life, And Together Constitute A Living Being In Life S Ratchet, Physicist Peter M Hoffmann Locates The Answer To This Age Old Question At The Nanoscale The Complex Molecules Of Our Cells Can Rightfully Be Called Molecular Machines, Or Nanobots These Machines, Unlike Any Other, Work Autonomously To Create Order Out Of Chaos Tiny Electrical Motors Turn Electrical Voltage Into Motion, Tiny Factories Custom Build Other Molecular Machines, And Mechanical Machines Twist, Untwist, Separate And Package Strands Of DNA The Cell Is Like A City An Unfathomable, Complex Collection Of Molecular Worker Bees Working Together To Create Something Greater Than Themselves Life, Hoffman Argues, Emerges From The Random Motions Of Atoms Filtered Through The Sophisticated Structures Of Our Evolved Machinery We Are Essentially Giant Assemblies Of Interacting Nanoscale Machines Machines Amazing Than Can Be Found In Any Science Fiction Novel Incredibly, The Molecular Machines In Our Cells Function Without A Mysterious Life Force, Nor Do They Violate Any Natural Laws Scientists Can Now Prove That Life Is Not Supernatural, And That It Can Be Fully Understood In The Context Of Science Part History, Part Cutting Edge Science, Part Philosophy, Life S Ratchet Takes Us From Ancient Greece To The Laboratories Of Modern Nanotechnology To Tell The Story Of Our Quest For The Machinery Of Life.Lifes Ratchet

    Hoffmann, in Life s Rachet, sets out for himself a substantial task to explain the emergence of life, along with its relentlessly growing complexity over time He does neither, and gloriously Or as the brilliant Wolfgang Pauli would say of his students poor answers, It s not even wrong Hoffmann is a physicist It is that bag of talents that he brings to bear on the perennial questions of evolutionary biology He sees his background in material sciences as an asset in the problem of life, a misplaced hubris to be sure His solutions to those evolutionary questions, surprise surprise, are to be found in the physical sciences, the bump and clang of molecules in motion, oozing energy and possibility captured by molecular machines that build forward their own sophistication He profits a great deal by not understanding the most basic challenges facing those who are seriously addressing the problems of life s origins and evolution Hoffmann makes a parody of life s origins, and something less flattering of its evolution As Charles Darwin himself a...

    This is a popularization in the sense of intended for non scientists, but it s fairly complex in a couple of ways so that it s not a simple read First, it covers a lot of ground that you might or might not be interested in, from history of science to creationism to lots of technical detail piconewtons, equivalent temperature gains from the chemical reaction of single molecules, and much I personally found the breadth to be too much, though only by a little Second, some of the technical material is pretty technical We work through gentle introductions to statistical mechanics, what the second law of thermodynamics really means, introductory chemistry and biochemistry, atomic force microscopy, and quite a selection of other topics, before getting to what seems to be the heart of the book, explanations of the molecular machines that make life work, whose structure and workings we re just starting to understand We also get quite a bit of detail along the way about the clever experimental techniques that scientists have invented to figure these things out.So it s not very everyone, but if you re up for it and interested in ...

    Well, this is the first popular book which I have read about molecular machines It is well written and joy to read I admired clear style of Hoffmann throughout the book while conveying important and complex ideas on chance and necessity in emerging life As a physicist, I liked the chapters on Entropy and Maxwell s Demon the most where a basic statistical and thermodynamical picture of life process was sketched Maybe only caveat was the long introduction of vital forces and lengthy debates between different schools of ideas at the ancient era.However, I think it is a legitimate approach to show the reader what old guys were contemplating while trying to elucidate life s machinery I highly recommend the book if you want to look closely to the self sufficient mechanism of life at the smal...

    I gave up after about 10%.Big excitement discovery of the millennium is pronounced at the very beginning And then the author bores you to tears with Aristotle s birth year, death year and his arguments with his contemporaries Seriously, any popular science book starting with a history chapter should be banned It ref...

    If you only read one book concerning the significance of the second law of thermodynamics to life itself, this would be a good one.

    Carl Sagan opened our minds to the vastness of the universe, Peter Hoffmann helps us peer into the incredibly small.

    Great book highlighting one of the biggest success stories of reductionism A few key takeaways 1 It is only at the nanoscale that different forms of energy electrical, chemical, mechanical can be easily interchanged and utilized effectively This means that most of life in the physical Universe likely follows a similar evolutionary path At le...

    Hm don t even know what to think It was interesting, but without clearly expressed one subject Or rather expression of it in just a few sentences wasn t enough for me OK, I clearly understand the concept that people are rarely interested in complex things and as a consequence don t see how evolution or anything works as I m saying in these cases you can t get the information edge when being in the game , but explaining it in one sentence if you thought about it does nothing On the other hand, I should admit I am not interested in explaining complex things for others either, so book was good for me just fro few sentences I didn t thought before For ex., molecular evolution, when proteins seek low energy states Years ago participated in World Community Grid, but didn t fully understood ...

    Here be dragons finger pointed Fermi on hazy shadowy picture of nucleus.Nowadays by using our AFM s, we can wander way down across atomic scale with our quantum theory, and we have no doubt that Mr Fermi was not far from the truth, in some sense.In the summary of the book it is explained what the Life s ratchet is all about, thus I would rather avoid tauthology any of kindhowever, the future reader must have some basic knowledge of particle physics, chemistry, cellular biology, evolution theory, genetics, because here you gonna meet a lot of scientists from the past, even Mr Cardano He is obviously one of the main players in Life s Ratchet, not because of his invention of Cardan shaft, but because of the probabilistic theory that is a tool for statistical mechanics Don t worry, the author will make his best to you understand the statistical mechanics The Life s ratchet once it s unfold in full before your eyes and start sink into your mind, in some people, depending on their global worldview, may cause anger, disappointment, sadness, depression, or ...

    Peter Hoffman is one of the many physicists who straddles the line between physics and microbiology In this book, he does that quite successfully His aim is to show that what we see and call life can be identified by the actions of certain molecules that in aggregate drive the activity of cells The overriding principle governing the emergence of these molecules is chaos and necessity The author admonishes those who claim that the complexity of life requires an autonomous life force, a divine aspect or intelligent design...
