Inflationary cosmology has been developed over the last twenty years to remedy serious shortcomings in the standard hot big bang model of the universe. Taking an original approach, this textbook explains the basis of modern cosmology and shows where the theoretical results come from. The book is divided into two parts; the first deals with the homogeneous and isotropic model of...(展开全部)

膨胀宇宙学在过去的20年中的为了解决标准宇宙热大爆炸模型遇到的问题而发展起来的。本教程运用原始的方法解释了现代宇宙学的基础以及揭示了理论结构的由来。 本书分为两大部分：第一部分讲述了宇宙的均匀同向模型；第二部分讨论了如何运用观察到的宇宙结构揭示起始的非均匀性。传统高度数字化的题目：如原始核合成，宇宙微波背景各向异性的解析处理方法，膨胀和量子宇宙扰动理论页得以详述。通过更多猜测性观点的讲述本书将读者带入到当前宇宙学研究的前沿。 读者对象：本书适用于物理专业的学生，天体物理学家以及对理论物理学感兴趣的科研人员。 目次：（一）均匀各向同性的宇宙：膨胀宇宙的运动学和动力学；光传播和地平传播；热宇宙；早期宇宙；膨胀Ⅰ：均匀极限；（二）非均匀宇宙：牛顿理论中的引力不稳定性；广义相对论引力不稳定性；膨胀Ⅱ：原始非均匀起源；宇宙微波背景各向异性。

This is a pre-1923 historical reproduction that was curated for quality. Quality assurance was conducted on each of these books in an attempt to remove books with imperfections introduced by the digitization process. Though we have made best efforts - the books may have occasional errors that do not impede the reading experience. We believe this work is culturally important and...(展开全部)

In these Messenger Lectures, originally delivered at Cornell University and recorded for television by the BBC, Richard Feynman offers an overview of selected physical laws and gathers their common features into one broad principle of invariance. He maintains at the outset that the importance of a physical law is not "how clever we are to have found it out, but . . . how clever...(展开全部)

The Little Book of Cosmology provides a breathtaking look at our universe on the grandest scales imaginable. Written by one of the world’s leading experimental cosmologists, this short but deeply insightful book describes what scientists are revealing through precise measurements of the faint thermal afterglow of the Big Bang—known as the cosmic microwave background, or CMB—and...(展开全部)

Blockchain technology is a combination of three popular concepts: cryptography, peer-to-peer networking, and game theory. This book is for anyone who wants to dive into blockchain from first principles and learn how decentralized applications and cryptocurrencies really work.This book begins with an overview of blockchain technology, including key definitions, its purposes and characteristics, so you can assess the full potential of blockchain. All essential aspects of cryptography are then presented, as the backbone of blockchain. For readers who want to study the underlying algorithms of blockchain, you’ll see Python implementations throughout.You’ll then learn how blockchain architecture can create decentralized applications. You’ll see how blockchain achieves decentralization through peer-to-peer networking, and how a simple blockchain can be built in a P2P network. You’ll learn how these elements can implement a cryptocurrency such as Bitcoin, and the wider applications of blockchain work through smart contracts. Blockchain optimization techniques, and blockchain security strategies are then presented. To complete this foundation, we consider blockchain applications in the financial and non-financial sectors, and also analyze the future of blockchain. A study of blockchain use cases includes supply chains, payment systems, crowdfunding, and DAOs, which rounds out your foundation in blockchain technology.
