Anyone truly wanting to understand general relativity, quantum field theory or any other area of modern physics first needs to master Lagrangian mechanics. Lagrangian mechanics is the fundamental framework used to describe all of modern physics.
The issue with most resources teaching Lagrangian mechanics is that they don’t truly teach you the why behind it – all they do is give you another approach for solving madeup mechanics problems. But what if it didn’t have to be this way? What if you could truly learn Lagrangian mechanics the right way?
The good news is that this course will do exactly that for you. It will take you on a journey through the very fundamentals, theory, mathematics and advanced applications of Lagrangian mechanics. You’ll learn Lagrangian mechanics in a completely unique way you’ve likely never seen before.

The Truth About Lagrangian Mechanics...
If you've ever opened a textbook on quantum field theory or some other area of modern physics, you'll probably have come across Lagrangian mechanics.
Let me just tell you right now  Lagrangian mechanics is one of the most important subjects you'll need to learn throughout your physics journey.
The issue is that Lagrangian mechanics is often taught in a way that does not truly explain why it's needed and instead leaves you wondering “who cares about this?”
The true reason why Lagrangian mechanics is so incredibly powerful is that it gives you a general framework for describing literally any area of modern physics... but almost no one will teach you it this way.
Whether you want to learn:
 Electrodynamics
 Special and general relativity
 Quantum field theory
 String theory
You absolutely need to have a deep understanding of Lagrangian mechanics to even get started on any of these topics.
For myself, learning Lagrangian mechanics was the biggest catalyst that enabled me to understand highlevel physics and I believe it will be for you too.
Today, I can confidently say that learning Lagrangian mechanics was the single most important thing I ever did in terms of my physics education.
However, if there is one thing I wish I would've had back when I first began learning it, it would be a dedicated resource that introduces Lagrangian mechanics completely from scratch and gives you everything in one place.
That is exactly what this course will give you.
Lagrangian Mechanics & Field Theory: A Complete SelfStudy Course is a complete resource specifically designed to teach you everything you'd possibly need to know about Lagrangian mechanics and modern field theory  the fundamentals, prerequisites, theory, math and practical applications. It's all here.
Here's Exactly What You'll Learn
The course is essentially divided into two main parts. The first part covers Lagrangian mechanics and the second part covers field theory.
In total, the course includes 790 pages worth of completely unique material that teaches you these two topics from scratch.
Along with the main course content highlighted above, you will also get:
 Five worksheets that include over 40 practice problems you can do to build a much more practical understanding
 Solution manual with 90+ pages of detailed, stepbystep solutions to every problem
 Bonus resources covering the use of complex numbers in field theory, the most useful coordinate systems in physics as well as the Coordinate Systems & Basis Vectors cheat sheet

All content available in PDF format, so you can download or print it out if you wish
Below are some samples of the style of explanations you can expect to find inside the course.
This is exactly the resource I wish I had back when I first began learning Lagrangian mechanics – and I'm confident you'll think the same after taking this course!
