Frank Close delves into fundamental particles and forces to find clues to a deep unsolved mystery of physics why is matter neutral Human beings have long been aware of the electric and magnetic forces around us from the electrostatic charge built up by rubbing amber with fur to the pull of the lodestone and scientific investigation showed that the two are intimately connected as electromagnetism Lightning shows how devastating electricity can be in nature while humans learned to exploit the flow of negatively charged electrons that make up an electric current In the early part of the 20th century the experiments of Ernest Rutherford showed that at the heart of atoms lies a positively charged nucleus The positive charge comes from protons Atoms are neutral because the charges of the electron and proton cancel out And that enables the much weaker force of gravity always attractive to dominate at large scales building planets stars and galaxies Things would have been very different had the charges not cancelled As far as we know the charges of the proton and electron are opposite and exactly equal even though the proton is far bigger and composed of three quarks tightly bound within it while the electron is a fundamental particle But why are they

In For the Love of Physics beloved MIT professor Walter Lewin whose riveting physics lectures made him a YouTube super star takes readers on a remarkably fun inventive and often wacky journey that brings the joys of physics to life For the Love of Physics captures Walter Lewin s extraordinary intellect passion for physics and brilliance as a teacher Bill Gates For more than thirty years as a renowned professor at the Massachusetts Institute of Technology Lewin s lectures made physics not only accessible but fun whether putting his head in the path of a wrecking ball supercharging himself with three hundred thousand volts of electricity or demonstrating why the sky is blue and clouds are white In For the Love of Physics Lewin takes readers on a marvelous journey opening our eyes as never before to the wonders of physics and its amazing ability to reveal the beauty and power embedded in our world Could it be true that we are shorter standing up than lying down Why can we snorkel no deeper than about one foot below the surface Why are the colors of a rainbow always in the same order can we stretch a hand out and touch one Using superbly clear and simple explanations of phenomena we ve always wondered about such as what the big bang would have sound

Internationally renowned theoretical physicist and bestselling author Lawrence Krauss offers provocative revelatory answers to the biggest philosophical questions Where did our universe come from Why does anything exist And how is it all going to end Why is there something rather than nothing is the question atheists and scientists are always asked and until now there has not been a satisfying scientific answer Today exciting scientific advances provide new insight into this cosmological mystery not only cansomething arise from nothing but something willalwaysarise from nothing A mind bending trip back to the beginning of the beginning A Universe from Nothingauthoritatively presents the most recent evidence that explains how our universe evolved and the implications for how it s going to end It will provoke challenge and delight readers to look at the most basic underpinnings of existence in a whole new way In the words of Richard Dawkins this could potentially be the most important scientific book since Darwin s On the Origin of Species

Most people remember chemistry from their schooldays as largely incomprehensible a subject that was fact rich but understanding poor smelly and so far removed from the real world of events and pleasures that there seemed little point except for the most introverted in coming to terms with its grubby concepts spells recipes and rules Peter Atkins wants to change all that In this Very Short Introduction to Chemistry he encourages us to look at chemistry anew through a chemist s eyes in order to understand its central concepts and to see how it contributes not only towards our material comfort but also to human culture Atkins shows how chemistry provides the infrastructure of our world through the chemical industry the fuels of heating power generation and transport as well as the fabrics of our clothing and furnishings By considering the remarkable achievements that chemistry has made and examining its place between both physics and biology Atkins presents a fascinating clear and rigorous exploration of the world of chemistry its structure core concepts and exciting contributions to new cutting edge technologies ABOUT THE SERIES The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every sub

¿Sabes que hiciste hace 8 minutos y 19 segundos? Ese es el tiempo que tarda en llegar la luz del sol a la Tierra, y el Sol es la estrella que nos ilumina y calienta, la más cercana a nosotros y sin la cual no habria vida en nuestro planeta. Pero surgen muchas mas preguntas: ¿cuanto de lejos esta el agujero negro del centro de nuestra galaxia, la Via Lactea? ¿Cuanto de nuestras galaxias vecinas como Andromeda? ¿Cuanto hace que salio la luz de Andromeda, cuantos millones de kilometros recorrio hasta llegar a nuestro planeta y que sucedia entonces en la Tierra? Este libro nace del dialogo entre un astrofisico y un prehistoriador cuando conversan sobre el tiempo que transcurrio en llegar la luz de ciertos astros o eventos astronomicos a la Tierra y que sucedia en aquellos momentos en la historia de la humanidad. A traves de sus paginas podremos averiguar la luz de que astro alcanzo la Tierra cuando nuestros antepasados inventaron la escritura, nuestra especie Homo sapiens dio sus primeros pasos o nuestros tataratatarabuelos los Austrolopithecus vivieron en Çfrica.

El ejercicio físico produce beneficios indudables en todo el organismo, en nuestra salud y, por supuesto, en el cerebro. Sin embargo, en los últimos años han pasado relativamente desapercibidos numerosos avances neurocientificos que señalan que tipo de ejercicio es bueno para segun que aspectos; que la intensidad del ejercicio es un factor crucial para obtener resultados concretos; cuales son las areas cerebrales que se ven beneficiadas por el ejercicio moderado o vigoroso, asi como los ultimos avances sobre el efecto que tiene en la depresion, la ansiedad, la cognicion, el envejecimiento y la neurodegeneracion. Aunque estamos lejos de poder elaborar un plan personalizado de ejercicio util para cada ser humano, que produzca beneficios para los diferentes sistemas fisiologicos del organismo sin incrementar el estres, no cabe la menor duda de que el sedentarismo es el enemigo de un cerebro sano. Esta obra totalmente actualizada incorpora ademas dos nuevos capitulos donde se presentan los dos extremos evolutivos de la percepcion humana sobre la actividad fisica, destacando los ultimos avances en el conocimiento cientifico y social, y las recomendaciones correspondientes para obtener el maximo beneficio para nuestro cerebro de una vida activa fisicamente. Se analizan tambien las evidencias sobre la actividad fisica de nuestros ancestros para averiguar si el ejercicio es una actividad inherente a nuestra especie.

The epic story of human evolution from our primate beginnings more than five million years ago to the agricultural eraOver the course of five million years our primate ancestors evolved from a modest population of sub Saharan apes into the globally dominant species Homo sapiens Along the way humans became incredibly diverse in appearance language and culture How did all of this happen In The Five Million Year Odyssey Peter Bellwood synthesizes research from archaeology biology anthropology and linguistics to immerse us in the saga of human evolution from the earliest traces of our hominin forebears in Africa through waves of human expansion across the continents and to the rise of agriculture and explosive demographic growth around the world Bellwood presents our modern diversity as a product of both evolution which led to the emergence of the genus Homo approximately 2 5 million years ago and migration which carried humans into new environments He introduces us to the ancient hominins including the australopithecines Homo erectus the Neanderthals and others before turning to the appearance of Homo sapiens circa 300 000 years ago and subsequent human movement into Eurasia Australia and the Americas Bellwood then explores the invention of agric
