Exploring the future of language, this book addresses the potential for a universal language while considering the fate of mother tongues. It delves into the implications of linguistic unity and the cultural significance of native languages, preparing readers for a world where communication transcends traditional barriers. The work invites reflection on identity, heritage, and the evolving nature of human expression in a rapidly changing society.
The book presents a straightforward definition of health, emphasizing the ability to engage in desired activities as a key indicator of well-being. It highlights the importance of balancing intelligence, which provides factual understanding, with emotional clarity, which reveals true desires. This approach encourages readers to consider both rational and emotional aspects when making choices related to health and personal fulfillment.
Exploring the concepts of space and time, the book introduces a "frozen universe" to define a segment of time between two events. It presents a unique perspective on an absolute stationary point in the universe. The narrative features notable figures, including Tang Ke-Yun, who demonstrated that gravity travels at the speed of light, and Stephen Hawking, a renowned physicist. Through these discussions, the book delves into profound scientific theories and their implications for our understanding of the universe.
The book provides a comprehensive overview of the foundation of special relativity, structured into three distinct parts. It begins with the outline of special relativity, including key experiments like the Michelson-Morley experiment and the Lorentz Transformation. The second section delves into the mathematical principles underlying these concepts. Finally, the conclusion discusses the relationship between Lorentz Transformation and Galilean Transformation, emphasizing the nuances of time equations in the context of special relativity.
The book introduces the Lorentz Transformation, a fundamental concept in Einstein's theory of relativity, tailored specifically for high school students. It simplifies complex ideas through clear explanations, engaging examples, and practical applications, making advanced physics accessible. Readers will explore the implications of time dilation and length contraction, enhancing their understanding of how speed affects time and space. This resource aims to inspire curiosity and provide a solid foundation in modern physics for young learners.
Some day in the near future, people will use same language and they may keep or quit their mother tongues. This book is prepared for that day. Based on Pinyin system the author combined the International Phonetic Alphabet (IPA) of English and Chinese into 47 symbols of Auxiliary Phonetic Alphabet (APA). The author also worried about the future of science. Most people know that science is based on measurements. To make a valid measurement people must record related event time and event location. That means, to secure our science, people must have a firm common sense of spacetime. In this book, knowledge is the useful part of history which is ready for you as of here and now, plus your current ability on logic, both of the basic reasoning and the extended imagination. A piece of science is a knowledge comes with formula or formulas. The common sense is the intersection of individual's knowledge in the related area while history is whatever happened in the past, especially those related to human beings. What are your definitions of knowledge, science and common sense?
