What you will learn

This book will help you understand the universe in a simple way.
From the beginning: 0, the void - singularity - infinity, to our 3D world. You will learn about atoms, particles, forces of nature, space, time, light, black holes, and quantum physics.

Lots of interesting things to read. You will understand the basics of physics, how the world works, parts of yourself, the cosmos, and some mind breaking ideas...

My main inspiration: Niels Bohr & complementarity.

His approach in quantum physics is what I follow. Good colleague of Albert Einstein — people know him less, but Niels Bohr was the master of the quantum world.

And of course, you'll learn physics is awesome.

About

a scientist.

I studied 3 years at Henri Poincaré University in Nancy, France, for a degree in particle physics & mathematics. My minors were astrophysics & chemistry. I left my studies a couple years after the passing of my father, but never stopped studying. This book is a collection of my ongoing explorations in physics.

I initially studied physics, then later worked as a photographer in London, also working in a cultural venue. Later, I returned to France, studied programming, and earned a diploma in software development. Today I work as a developer.
