When the multiverse and many-worlds collide - physics-math - 01 June 2011 Read full article Continue reading page |1|2 Editorial: "God deserves a cosmological explanation" TWO of the strangest ideas in modern physics - that the cosmos constantly splits into parallel universes in which every conceivable outcome of every event happens, and the notion that our universe is part of a larger multiverse - have been unified into a single theory. The problem is the observability of our universe. Cosmologists reconcile this seeming contradiction by assuming that the superposition eventually "collapses" to a single state. In an attempt to find a more satisfying way to explain the universe's observability, Bousso, together with Leonard Susskind at Stanford University in California, turned to the work of physicists who have puzzled over the same problem but on a much smaller scale: why tiny objects such as electrons and photons exist in a superposition of states but larger objects like footballs and planets apparently do not. Physicists call this process "decoherence".
Islamic Golden Age History of the concept There is no unambiguous definition of term, and depending on whether it is used with a focus on cultural or on military achievement, it may be taken to refer to rather disparate time spans. Thus, one author would have it extend to the duration of the caliphate, or to "six and a half centuries", while another would have it end after only a few decades of Rashidun conquests, with the death of Umar and the First Fitna. During the early 20th century, the term was used only occasionally, and often referred to the early military successes of the Rashidun caliphs. Causes Religious influence The various Quranic injunctions and Hadith, which place values on education and emphasize the importance of acquiring knowledge, played a vital role in influencing the Muslims of this age in their search for knowledge and the development of the body of science.

How to Learn (But Not Master) Any Language in 1 Hour (Plus: A Favor) | The Blog of Author Tim Ferriss Deconstructing Arabic in 45 Minutes Conversational Russian in 60 minutes? This post is by request. How long does it take to learn Chinese or Japanese vs. Spanish or Irish Gaelic? Here’s the reasoning… Before you invest (or waste) hundreds and thousands of hours on a language, you should deconstruct it. So far, I’ve deconstructed Japanese, Mandarin Chinese, Spanish, Italian, Brazilian Portuguese, German, Norwegian, Irish Gaelic, Korean, and perhaps a dozen others. How is it possible to become conversationally fluent in one of these languages in 2-12 months? Consider a new language like a new sport. There are certain physical prerequisites (height is an advantage in basketball), rules (a runner must touch the bases in baseball), and so on that determine if you can become proficient at all, and—if so—how long it will take. Languages are no different. Six Lines of Gold Here are a few questions that I apply from the outset. 2. 3. 4. It doesn’t take much to answer these questions.
The Complete List of Higher Dimensional Apps for phones, computers, and tablets. : fived Hyperdonut : 5D Tiger Torus (((II)I)(II)) Wormholes and Donut Holes | 4 gravitons I’ve heard people claim that in order to understand wormholes, you need to understand five-dimensional space. Well that’s just silly. A wormhole is often described as a hole in space-time. It can be imagined as a black hole where instead of getting crushed when you fall in to the center, you emerge somewhere else (or even some-when else: wormholes are possibly the only way to get time travel). They’re a staple of science fiction, even if they aren’t always portrayed accurately. Probably not what a wormhole looks like How does this work? Suppose that you live on the surface of a donut. It’s a simple life Let’s say that one day you’re sitting on the pink side of the donut, near the center. That’s really all a wormhole is. Now earlier I said that you don’t need to understand five-dimensional space to understand wormholes, and that’s true. Like this: Like Loading...
