The grimace physics class 1 classical physics
The universe is 65.438+0.38 billion years old, the origin of mankind is 2 million years, and Homo sapiens has appeared for more than 200,000 years. The history of human civilization is 6000 years, and rational thinking is only about 2000 years. The modern scientific system was founded only 400 years ago, and modern physics was founded only 300 years ago. Now, we know that the two pillars of the world have only been established for 100 years. ...
Well, in the history of the universe, the history of mankind is only a short moment. How should we know this vast and magical world?
This book begins with the germination of ignorance, doubt and reason. Along the development of physics, this paper expounds the basic theories and important contributions of Galileo, Kepler, Newton and Lorenz, covering the key knowledge of motion and force, light and electromagnetism in middle school physics.
The text is humorous but rigorous, the illustrations are exquisite and the images are easy to understand, and there are links to physical knowledge throughout.
Let's follow the author back to the past, argue, worry, struggle, practice and challenge with physicists in order to explore the truth, and talk about the past lives of classical physics.
History of Relativity: Lesson 2 of grimace Physics
In Newton's world, everything seems quiet, beautiful and harmonious. Everything is born in the past, lives in the present and looks forward to the future. We live in this three-dimensional space and habitually take everything for granted, but the physics community is not so calm.
19 In the 1980s, the explanation of some phenomena by classical physics was inadequate, and the classical physics building was in jeopardy. At the beginning of the 20th century, Einstein founded the theory of relativity, which led us on the journey of "chasing light".
Although the speed of light is fast, ideas can be achieved. In this book, the author shared with us the secret of Einstein's theory of relativity. Humorous language, vivid and easy-to-understand metaphors, silly and funny illustrations, and knowledge links seamlessly connected with teaching materials lead us to roam freely in four-dimensional space and give our thoughts a carefree trip.
The third lesson of grimace physics explores the microscopic world
What is the world made of? This is a very "boring" but extremely important problem, and it is also a problem that has been torturing people on earth but continues to promote the development of civilization. Philosophy, logic, conjecture, data ... I know that you are not only concerned about these, but also the story behind it.
There is everything you want here, as well as some important concepts in the textbook, such as quantum, blackbody radiation, ultraviolet catastrophe and wave-particle duality.
The story begins with chemical elements and atomic models. Scientists put forward the concept of "energy quantum" in the process of exploring some laws of the micro-world, that is, quantum.
The door of the quantum world has finally opened, but it is not the bright Wan Li as imagined, and the sky is full of dark clouds of "quantum ghosts".
Before the dark clouds dispersed, the photoelectric effect thundered and tore the physical sky. Einstein, Compton, Bohr, De Broglie, etc. The relationship between waves and particles becomes subtle, and Pauli develops the "deception" of quantum theory to a new height. Genius teenagers represented by Heisenberg and Dirac use their courage to spread youth in the quantum field. ...
Physics of grimace Lesson 4 Quantum Theory and Future
The grain puts on the vest of matrix, and the wave puts on the coat of differentiation. Everything seems beautiful, but the battle between wave and grain never stops.
As the saying goes, "Know yourself and know yourself, and fight every battle", and Bo Hezi has not been idle. After finding out the origin of the two sides, the world not only did not have peace, but ushered in a more exciting battle.
I thought physics was serious, definite and even a little stiff, but now "jumping", "probability" and "uncertainty" have become its most obvious labels. The more you want to see clearly, the less you can see clearly. Even Heisenberg said "uncertainty", and Bohr's complementary principle can't let the dust of the quantum world settle.
In the quantum entanglement, Schrodinger's cat became a dazzling star, which made us curious and fascinated. The sixth finger, horror experiment, parallel universe, decoherence ... endless stories make us a little dizzy.
It doesn't matter. In this book, the author will explain these wonderful stories vividly and clearly for you. This is a physics debate without smoke, which is as thrilling as survival in the wilderness.
Quantum theory is an insurmountable test. The founding fathers are getting old, and new forces are quietly born. What is its future? As long as we are in doubt, we should move on. ...
