Master the laws that run the universe
From Newton's laws to E = mc², Physics Unlocked gives high school students, curious self-learners, and career-changers a rigorous, jargon-free path through classical and modern physics — built around real problem-solving, not rote memorization.
Physics isn't about memorizing formulas — it's about building the kind of understanding that lets you derive them yourself, and that's exactly what we do here.— Tracy Burke

Who it's for
Is this you?
The AP Physics student
Needs a clear, structured path through mechanics, E&M, and waves to walk into the AP exam with genuine confidence — not just memorized formulas.
The curious self-learner
Has always been fascinated by how the universe works and wants a rigorous, satisfying grounding that goes deeper than pop-science explainers.
The returning adult student
Studied some physics years ago, remembers almost none of it, and wants to rebuild from scratch before enrolling in a college science or engineering program.
The career-changer
Transitioning into engineering, data science, or a technical field and needs the physics foundation their new path requires — without going back to school full-time.
The first-gen STEM student
Heading into a physics-heavy major without much prior preparation and looking for a clear, supportive on-ramp that builds real problem-solving skill.
The science enthusiast
Loves reading about relativity and quantum mechanics but wants to finally understand the math and reasoning underneath the popular explanations.

Tracy Burke
If you're reading this, I'm guessing physics has felt like a closed door at some point. Maybe the equations moved too fast in class, or a textbook made a simple idea sound impossibly complex, or you just never got a satisfying answer to the question every curious person eventually asks: why does any of this work?
I've been teaching physics long enough to know that the problem is almost never the student. It's the presentation. Physics, at its core, is a set of powerful ideas about how the universe behaves — and when those ideas are explained with the right analogy, the right diagram, and the right moment to pause and ask "does that make sense?", something remarkable happens. The confusion lifts. The pieces lock together. You see it.
That experience — the genuine "aha" — is what this school is built around. We start with the problem-solver's mindset: how to estimate, how to model, how to choose the right tool for a given situation. Then we work through mechanics, thermodynamics, waves, and electromagnetism with a consistent approach — always anchoring the math to something physical you can picture, always checking our answers against reality. By the time we reach special relativity, you'll have the intuition and the tools to handle ideas that once seemed reserved for geniuses.
I want to be honest with you about something: this course will ask you to think hard. Physics rewards effort and patience in a way few subjects do. But I've designed every section so that the difficulty curve is a gentle climb, not a wall. Every concept is introduced with a real-world hook. Every equation earns its place.
Whether you're cramming for an AP exam, returning to science after years away, or simply driven by curiosity about how the world works — you belong here. The laws of the universe don't care about your background. They're waiting to be understood. Let's go unlock them.
