This work began with a simple question:
Can the entire universe be described through numbers and structure?
The motion of stars, the evolution of life, music, stories,
and changes in the human mind may seem unrelated,
yet over long stretches of time they form a single continuous history.
About This Work
This text is designed as a new kind of textbook.
It explains not only what is found in standard curricula,
but also ideas that are usually left unexplained.
Chapters and sections are used to organize the universe,
science, history, music, and human perception
into a single systematic narrative.
About the Author
The author name, Himeno Isoda, was taken from the name of a dog
who once lived alongside the author.
This work was created through collaboration
between a human author and ChatGPT.
On Science Fiction Elements
To spark curiosity and deepen understanding,
this work includes sections inspired by science fiction.
These are not merely fantasies,
but thought experiments designed to expand how we think.

or explored freely through the chapter list.

Somewhere within this long history,
you may find a chapter that connects directly to you.
