En junio de 2004 el equipo de los angeles preparatoria Carl Hayden, de Phoenix, sorprendió a todos los asistentes a los angeles competencia anual de robótica auspiciada por los angeles nasa cuando consequenceó ganador en el evento. No period para menos, el equipo estaba conformado por cuatro adolescentes, cuyas circunstancias a todas luces los colocaban en una situación poco aventajada. Se trataba de hijos de inmigrantes ilegales, provenientes de una escuela pública con recursos escasos para desarrollar un robotic que resultara competitivo. O al menos eso parecía. Su ingenio, talento y perseverancia, además del apoyo de sus maestros, los hicieron merecedores a este galardón, por encima de equipos tan poderosos como el del mit, que cuenta con l. a. mejor escuela de ingeniería del mundo.
Los inventores retrata magistralmente l. a. agridulce historia de estos muchachos y sus familias, y el verdadero esfuerzo que implica conquistar el sueño americano.

Hali Felt's Soundings: The Story of the Remarkable Woman Who Mapped the PDF

By Hali Felt

Her maps of the sea ground were referred to as "one of the main striking achievements in glossy cartography", but nobody is aware her name.

Soundings is the tale of the enigmatic, unknown girl at the back of one of many maximum achievements of the twentieth century. earlier than Marie Tharp, geologist and talented draftsperson, the entire global, together with lots of the clinical group, notion the sea ground used to be an unlimited expanse of nothingness. In 1948, at age 28, Marie walked into the newly shaped geophysical lab at Columbia collage and virtually demanded a role. The scientists on the lab have been all male; the ladies who labored there have been relegated to secretary or assistant. via sheer determination and obstinacy, Marie used to be given the activity of analyzing the soundings (records of sonar pings measuring the ocean's depths) introduced again from the ocean-going expeditions of her male colleagues. the wedding of artistry and technology in the back of her research of this dry info gave delivery to an immense paintings: the 1st finished map of the sea flooring, which laid the basis for proving the then-controversial concept of continental drift.

When mixed, Marie's clinical wisdom, her eye for element and her ability as an artist published now not an unlimited empty airplane, yet a complete international of mountains and volcanoes, ridges and rifts, and a gateway to the prior that allowed scientists the potential to visualize how the continents and the oceans were created over time.

Just as Marie devoted greater than 20 years of her specialist existence to what turned the Lamont Geological Observatory, engaged within the activity of mapping each ocean in the world, she devoted her own existence to her nice friendship along with her co-worker, Bruce Heezen. companions in paintings and in lots of methods, companions in lifestyles, Marie and Bruce have been dedicated to each other as they rose to larger and larger prominence within the clinical group, in simple terms to be envied and at last pushed aside by way of their liked institute.

John Gribbin,Simonetta Frediani,Mary Gribbin's Il capolavoro di Einstein: Il 1915 e la teoria generale PDF

By John Gribbin,Simonetta Frediani,Mary Gribbin

Nella scienza i capolavori sono rari come nelle arti. in line with essere tali, in loro l. a. perfezione deve uguagliare los angeles dirompenza. Perché rivoluzionano il mondo, alla lettera. John Gribbin non esita a spendere l. a. parola «capolavoro» in keeping with l. a. teoria generale della relatività, che lo stesso Albert Einstein definì «la scoperta più preziosa della mia vita ... una teoria di incomparabile bellezza». Quando los angeles elaborò nella forma che conosciamo period trascorso un decennio dal 1905, ritenuto concordemente dagli studiosi il suo annus mirabilis: pochi mesi leggendari durante i quali, in un impeto di creatività scientifica che non si period più registrato dai tempi di Newton, aveva concepito anche l. a. teoria ristretta della relatività e scoperto los angeles legge dell’effetto fotoelettrico, che gli avrebbe poi valso il premio Nobel nel 1921. Gribbin tuttavia rivede l’opinione comune, posticipando il vero miracolo dal 1905 al 1915, quindi alla generalizzazione della teoria, questa sì in sconvolgente anticipo sui tempi della ricerca. L’estensione della relatività dagli oggetti che si muovono a velocità costante in linea retta al moto accelerato e alla gravità compie il prodigio di descrivere il nostro Universo e tutto lo spaziotempo che contiene. Nel secolo trascorso da allora, ciò che suscitò sconcerto si è through through consolidato – soprattutto durante gli ultimi cinquant’anni – come una delle teorie più comprovate dell’intera storia della scienza. Gribbin ne racconta l. a. gestazione e le vicissitudini con l. a. competente semplicità del grande divulgatore che non ignora gli intrecci tra scienza e vita.

Il teorema vivente: La mia più grande avventura matematica - download pdf or read online

By Cédric Villani,C. Gondard,P. Bellingeri

Gli occhi di Cédric Villani brillano dello scintillio quasi febbrile di chi ha trovato l. a. sfida della vita: l. a. dimostrazione che lo tormenta, l. a. soluzione che gli sfugge. Insieme al suo complice Clément Mouhot l. a. insegue according to più di due anni, fino a quando, nel 2010, los angeles medaglia Fields lo consacra nell'Olimpo dei matematici mondiali e il nuovo teorema viene accettato consistent with los angeles pubblicazione: cento pagine di un edificio meraviglioso costruito con le geometrie dei simboli.
Questo libro è los angeles storia di quell'avventura. Il racconto di una sfida, di viaggi e notti insonni, di ossessioni, rivalità, rivincite e ispirazioni. Villani ripercorre una caccia matematica che lo porta da Kyoto a brand new York, da Princeton a Hyderabad, in corsa contro il pace e i ricercatori concorrenti. Parla dei suoi maestri Boltzmann, Poincaré e Landau, della musica che l’ha spronato, del conforto della famiglia. E di quel momento di lucida esaltazione in cui “tutto sembra concatenarsi come in keeping with incantesimo”. Entriamo così nella mente di un genio capace di contagiare con il suo entusiasmo e di trasformare l. a. matematica in un mondo abitato dalla passione, dall'avventura e dal mistero.
