Everything That Glows is a book about the deepest idea in modern physics: that information is physical.
That to know a thing, to remember it, or to forget it is never free; that each costs something real and measurable; and that this single fact runs like a thread through heat and light, life and gravity, number and mind. It is the story of how a question about a cooling cup of coffee turned, over two centuries, into a question about everything.
It is written for the curious, not the credentialed. There is no prerequisite but attention. And it is here in full, free to read, because understanding should not sit behind a gate.
Questions you’ll get to live with
You don’t need the answers to begin — only the pull of the questions.
Why does forgetting a single bit of information release a tiny, unavoidable trace of heat?
What does a cup of coffee cooling on your desk have in common with a black hole?
Is mathematics something we discover, or something we invent — and could we ever run out of it?
Why does time run one way, when the laws underneath barely notice a direction?
What is a “particle,” really, once you stop picturing a tiny ball?
If the world is, underneath, made of information — whose is it, and where is it kept?
The twelve chapters
The book is one continuous story, read from the beginning. Here is the path ahead.

About
I am not a physicist. I am someone who could never stop asking how the world works, and who found out, slowly, that the asking is open to anyone. I wrote this book to share that, and to argue that the deepest ideas in science belong to everyone willing to look.
— Karl Meves
