# Physics from Finance: A gentle introduction to gauge theories, fundamental interactions and fiber bundles

What if there was an intuitive way to understand how nature fundamentally works? What if there was a book that allowed you to see the whole picture and not just tiny parts of it?

Thoughts like this are the reason that Physics from Finance now exists.

**What will you learn from this book?**

Get to know all fundamental interactions —Grasp how we can describe electromagnetic interactions, weak interactions, strong interactions and gravity using the same key ideas.

Learn how to describe modern physics mathematically — Understand the meaning and origin of the Einstein equation, Maxwell’s equations, and the Schrödinger equation.

Develop an intuitive understanding of key concepts — Read how we can understand abstract ideas like Gauge Symmetry, Internal Spaces, Gauge Fields, Connections and Curvature using a simple toy model of the financial market.

Get an understanding you can be proud of — Learn why fiber bundles and group theory provide a unified framework for all modern theories of physics.

**Physics from Finance is the most reader-friendly book on the geometry of modern physics ever written.**

Here’s why.

First of all, it's nothing like a formal university lecture. Instead, it’s like a casual conservation with a more experienced student. This also means that nothing is assumed to be “obvious” or “easy to see”.

Each chapter, each section, and each page focusses solely on the goal to help you understand. Nothing is introduced without a thorough motivation and it is always clear where each formula comes from.

The book contains no fluff since unnecessary content quickly leads to confusion. Instead, it ruthlessly focusses on the fundamentals and makes sure you’ll understand them in detail.

The primary focus on the readers’ needs is also visible in dozens of small features that you won’t find in any other textbook

In total, the book contains more than 100 illustrations that help you understand the most important concepts visually.

Whenever a concept is used which was already introduced previously, there is a short sidenote that reminds you where it was first introduced and often recites the main points. In addition, helpful diagrams make sure you won’t get lost.
