Live Online Experimental Physics Classes
Learn physics the way scientists actually do
Students don’t just learn facts—they design experiments, test ideas, and build scientific knowledge for themselves. Classes are taught live by Dr. Katerina Visnjic, Princeton physicist and creator of the award-winning Physics 4 Life YouTube channel.
“Dr. Kat guides students to experience discovery firsthand. She doesn’t just build their knowledge base like a Wikipedia page—she helps create true scientists.”

Not sure where to start?
Electromagnetism course (recommended starting point): Builds a deep foundation and introduces students to big ideas that connect physics together while also introducing them to the process of doing science itself — making observations, and designing experiments to refine their understanding. And yes — we do circuits too!
Circuits Lab Course: Best for students with a strong interest in building, tinkering, and exploring electronic systems. Also a great next step for students who want to go deeper into electronics after the Electromagnetism course.
