Malaysian high schoolers analyse real muon detector data using Python. Live proof of Einstein's relativity — right in your browser.
Cosmic rays — high-energy particles from distant stars and supernovae — constantly bombard Earth's upper atmosphere. When they smash into air molecules, they produce a shower of new particles called muons.
Muons travel toward Earth at nearly the speed of light. Their lifespan is just 2.2 millionths of a second — they should decay long before reaching the surface. Yet they arrive in their millions every minute.
💡 This is Einstein's Special Relativity in action. At near-light speeds, time slows down for the muon — giving it enough time to complete the journey. Every detection is live proof that time is not absolute.
Every second, hundreds of muons pass through your body. In this class, you will catch them.
Data from real detectorYou won't watch slides. You'll write Python code and make actual measurements with data from a real particle detector — exactly how professional physicists do it.
The data you analyse comes from a real two-scintillator muon detector — the same core technology used in high-energy physics labs worldwide, miniaturised for education and fieldwork.
You won't just learn about a muon detector. You'll analyse data from one — the same way physicists do at CERN, Fermilab, and KEK!
All sessions are live and interactive. Ask the instructor anything — they're a real particle physicist.
Teaching physics for years, I always told students about muons as evidence for relativity — but it remained abstract. Having real detector data to analyse makes the theory tangible in a way no textbook can.
Every student leaves with tangible outcomes — not just knowledge, but proof of what they can do.
