Physics learning
that works

Learn Fast.

Our concise, high-quality lessons are optimized for learning efficiently.

Remember Forever.

Built-in spaced repetition algorithms ensure you review concepts at the exact moment you're about to forget them.

Just 20 Minutes a Day.

Replace hours of video lectures and inefficient studying with short, high-intensity learning sessions.

Your journey to Physics mastery

Personalized Learning Plan

We make sure you're always given the right lessons at the right time, so you can maximize learning and minimize frustration.

Start with a diagnostic test to find your Knowledge Frontier.

Then move forward at your own pace, and never get stuck.

Personalized Learning Plan

Efficient, Effective Learning

Complete each lesson in 20 minutes or less of focused effort.

Experience tons of animations and visualizations that make complex concepts easy to understand.

Get instant feedback on your answers so you can quickly upgrade your understanding instead of repeating mistakes.

Efficient, Effective Learning

Adaptive review

Save time and maximize long-term retention by only reviewing content when it's most needed.

We enhance the traditional spaced repetition system by using the knowledge graph - when you demonstrate mastery of an advanced concept, we know that the basic concepts used are also mastered.

"I'm loving what you've built so far. This is huge for me, because for the last few years I've been questioning what brings me joy & who I am almost to an existential level. I know I like learning and I like jigsaw puzzles, but I didn't feel passionate about anything."

"My expectation was, that I'll finally be able to put some hard knowledge behind my existing surface level knowledge. I can happily say that the platform delivered. :)"

"I discovered @physicsgraph just a day before my flight and I haven't been able to put it down since. Huge respect to @sutherlandphys and @JeffreyBiles for building something truly special. You couldn't ask for a better introduction to node-based, spaced repetition learning."

"What I really liked about the platform is the pacing and the adaptability of it... Keep it up for a few weeks and before you know it you're doing real full fledged quantum computation that is directly used in things like Deutsch's algorithm. It's incredibly approachable even if you only have some basic college level math under your belt."

Brandon Warren

Senior Software Engineer, Zonar Systems

"I had some previous exposure to quantum computing, thanks to an IBM online tutorial and their cloud-accessible quantum computers. I also recently tried to participate in a quantum hackathon, but the open issues I investigated were way over my head. Now after taking the course from Lemnisket I'm ready to take another swing at it."

Bianca Herrera

"This course wasn't just another online program. What they're building in the quantum education space is already making a real impact. It was so encouraging to engage with material that was accessible without compromising depth. A huge thanks to Lemnisket for helping spark a further interest in Quantum Computing!"
