『全てを数で現す論文』磯田姫乃著(ChatGPT協力)

Introduction

This book is a new textbook intended to **express in numbers, compare, and verify** various subjects, ranging from space, life, science, civilization, history, film, anime, music, and science fiction. It is intended for a wide range of readers, from junior high school students to experts.

To be accessible even to beginners without compromising scientific rigor, it explicitly states definitions and assumptions at the outset.

It emphasizes diagrams, a minimal number of equations, and the mapping to observable quantities and statistics.

Each section is consistently structured in the order of Thesis → Evidence → Verifiability. That is, we present a hypothesis (what we ask),

present the theories, data, and estimation methods that serve as evidence (why we can say that), and finally, we evaluate the uncertainty, systematic errors, and reproducibility (how far we can say / what we cannot say yet) to draw a line. Terms are defined upon their first appearance, and abbreviations are kept to a minimum.

Readers can easily trace back to original sources and advanced materials through the references and footnotes at the end of each chapter.

There are three learning goals for this textbook as a whole: (1) Training in translating abstract concepts into observable quantities, (2) The perspective of comparing different fields using “the same dimensions and the same system of units,” and (3) The attitude of expressing the strength of a conclusion in numbers and distinguishing between hypotheses and established facts. By the time you finish this book, you should have a three-dimensional view of what it means to “express everything in numbers” and how it contributes to academic research, education, and social implementation.

Now, let’s begin by gaining an overview of the timeline of the universe and sharing the overall roadmap. As needed, you can always navigate to the section list and learn about topics that interest you.
