Hardback or Cased Book. Etat : New. Life's Ratchet: How Molecular Machines Extract Order from Chaos. Book.

Etat : As New. Unread book in perfect condition.

Hardback. Etat : New. Life is an enduring mystery. Yet, science tells us that living beings are merely sophisticated structures of lifeless molecules. If this view is correct, where do the seemingly purposeful motions of cells and organisms originate? In Life's Ratchet , physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.Below the calm, ordered exterior of a living organism lies microscopic chaos, or what Hoffmann calls the molecular storm,specialized molecules immersed in a whirlwind of colliding water molecules. Our cells are filled with molecular machines, which, like tiny ratchets, transform random motion into ordered activity, and create the purpose" that is the hallmark of life. Tiny electrical motors turn electrical voltage into motion, nanoscale 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 workers working together to create something greater than themselves.Life, Hoffman argues, emerges from the random motions of atoms filtered through these sophisticated structures of our evolved machinery. We are agglomerations of interacting nanoscale machines more amazing than anything in science fiction. Rather than relying on some mysterious life force" to drive them,as people believed for centuries,life's ratchets harness instead the second law of thermodynamics and the disorder of the molecular storm.Grounded in Hoffmann's own cutting-edge research, Life's Ratchet reveals the incredible findings of modern nanotechnology to tell the story of how the noisy world of atoms gives rise to life itself.…

Etat : NUOVO. Roma, Franco Muzzio Editore cm.17x24, pp.352, brossura con copertina figurata. Il XXI secolo vedrà il declino del petrolio come fonte energetica principale. A livello internazionale esistono diverse valutazioni, ma anche quelle più ottimistiche prevedono che si raggiunga il massimo della produzione di petrolio non oltre il 2020. Da quel momento la domanda supererà l'offerta, ma i prezzi avranno già iniziato la loro crescita. Per quanti progressi si possano prevedere in questo campo, le fonti rinnovabili - sole, vento, biomasse, geotermia, onde e maree - sono di per se stesse intermittenti. Per queste ragioni è giunto il momento di investire in una nuova direzione: l'era dell'idrogeno, che rappresenta il vettore energetico pulito del futuro Presentazione di Edo Ronchi.…

Etat : MOLTO BUONO. Torino, Bollati Boringhieri cm.15x21,5, pp.320, legatura editoriale cartonata con sopraccoperta figurata a colori. Collana Nuovi Saggi Bollati Boringhieri, 25. Da millenni gli uomini si interrogano sulla natura ultima della vita, eppure le spiegazioni che sono state fornite nel corso della storia si possono dividere in due sole grandi categorie: da un lato c'è chi pensa che tutti i fenomeni vitali possono essere ricondotti al movimento di minuscole particelle fisiche; dall'altro c'è chi invoca un'entità speciale, una sostanza invisibile che anima la materia vivente dandole uno scopo. Chi la chiama Dio, chi slancio vitale o vis viva: sarebbe l'intelligenza cosmica necessaria a spiegare la mirabile organizzazione degli esseri viventi, così apparentemente diversa dal caos della materia bruta. La spiegazione vitalistica ha trionfato per secoli, benché della forza vitale non si sia mai trovata traccia. Democrito, Epicuro, La Mettrie e Darwin, campioni della visione meccanicista, erano considerati i materialisti da combattere. Nel frattempo la scienza è progredita ed è grazie agli enormi passi avanti compiuti nei decenni scorsi da fisici e biologi che Peter Hoffmann ha potuto scrivere questo libro, un vibrante e aggiornatissimo racconto che di fatto rovescia la prospettiva e condanna al fallimento ogni forma residua di vitalismo: il moto caotico e casuale delle molecole, unito alla necessità imposta dalle leggi fisiche, è tutto ciò che serve per spiegare la vita.…
