Download E-books Gravity: How the Weakest Force in the Universe Shaped Our Lives PDF

By Brian Clegg

A heritage of gravity, and a examine of its significance and relevance to our lives, in addition to its impact on different components of technological know-how.

Physicists will let you know that 4 forces keep an eye on the universe. of those, gravity may perhaps the obvious, however it is additionally the main mysterious. Newton controlled to foretell the strength of gravity yet could not clarify the way it labored at a distance. Einstein picked up at the easy premise that gravity and acceleration are interchangeable to plan his mind-bending basic relativity, exhibiting how topic warps house and time. not just did this clarify how gravity labored – and the way it appears basic gravitation has 4 separate parts – however it anticipated every thing from black holes to gravity's impression on time. no matter if it is the fact of anti-gravity or the unforeseen discovery ball and a laser beam drop on the similar cost, gravity is the strength that fascinates.

Download E-books Wizards, Aliens, and Starships: Physics and Math in Fantasy and Science Fiction PDF

By Charles L. Adler

From teleportation and house elevators to alien touch and interstellar commute, technological know-how fiction and delusion writers have get a hold of a few incredible and cutting edge principles. but how believable are those ideas--for example, may perhaps Mr. Weasley's flying vehicle within the Harry Potter books quite exist? Which suggestions may well truly take place, and which of them would not paintings in any respect? Wizards, extraterrestrial beings, and Starships delves into the main remarkable information in technology fiction and fantasy--such as time warps, form altering, rocket launches, and illumination via floating candle--and indicates readers the physics and math at the back of the phenomena.

With basic mathematical types, and quite often utilizing not more than highschool algebra, Charles Adler levels throughout a plethora of exceptional imaginings, from the works of Ursula ok. Le Guin to Star Trek and Avatar, to discover what may possibly develop into truth. Adler explains why myth within the Harry Potter and Dresden documents novels can't adhere strictly to clinical legislation, and while magic may possibly make clinical experience within the muggle global. He examines area go back and forth and wonders why it's not more cost-effective and extra universal this present day. Adler additionally discusses exoplanets and the way the hunt for alien existence has shifted from radio communications to space-based telescopes. He concludes by way of investigating the long run survival of humanity and different clever races. all through, he cites an abundance of technology fiction and fable authors, and comprises concise descriptions of reports in addition to an appendix on Newton's legislation of motion.

Wizards, extraterrestrial beings, and Starships will converse to an individual eager to learn about the correct--and incorrect--science of technological know-how fiction and fantasy.

Download E-books The Trouble With Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next PDF

By Lee Smolin

During this groundbreaking booklet, the popular theoretical physicist Lee Smolin argues that physics — the root for all different sciences — has misplaced its means. For greater than centuries, our realizing of the legislation of nature extended quickly. yet this present day, regardless of our greatest efforts, we all know not anything extra approximately those legislation than we knew within the Seventies. Why is physics unexpectedly in difficulty? And what do we do approximately it?

One of the main difficulties, in accordance with Smolin, is string thought: an formidable try to formulate a “theory of everything” that explains all of the debris and forces of nature and the way the universe got here to be. With its unique new debris and parallel universes, string conception has captured the public’s mind's eye and seduced many physicists.

But as Smolin unearths, there’s a deep flaw within the conception: no a part of it's been established, and not anyone is aware how one can attempt it. in truth, the idea seems to return in an enormous variety of models, which means that no test will ever manage to turn out it fake. As a systematic thought, it fails. and since it has soaked up the lion’s proportion of investment, attracted the very best minds, and successfully penalized younger physicists for pursuing different avenues, it's dragging the remainder of physics down with it.

With readability, ardour, and authority, Smolin charts the increase and fall of string concept and takes a desirable examine what is going to change it. a gaggle of younger theorists has all started to boost interesting rules that, in contrast to string thought, are testable. Smolin not just tells us who and what to observe for within the coming years, he bargains novel ideas for searching out and nurturing the easiest new talent—giving us an opportunity, in the end, of discovering the subsequent Einstein.

Download E-books The Lightness of Being: Mass, Ether, and the Unification of Forces PDF

By Frank Wilczek

Our knowing of nature’s inner most fact has replaced noticeably, yet virtually with out our noticing, over the last twenty-five years. Transcending the conflict of older rules approximately topic and area, acclaimed physicist Frank Wilczek explains a amazing new discovery: topic is outfitted from nearly weightless devices, and natural strength is the last word resource of mass. He calls it “The Lightness of Being.” area isn't any mere box, empty and passive. it's a dynamic Grid—a sleek ether— and its spontaneous job creates and destroys debris. This new knowing of mass explains the perplexing feebleness of gravity, and a stunning unification of all of the forces comes sharply into focus.
The Lightness of Being is the 1st booklet to discover the results of those progressive rules approximately mass, strength, and the character of “empty space.” In it, Wilczek masterfully offers new views on our brilliant universe and envisions a brand new golden age of primary physics.
