Simulations
Four Simulations You Can Run Here
Each reproduces a number from the course. They run in your browser — Python compiled to WebAssembly, nothing installed, nothing sent anywhere. Press Run, change the constants, run again.
Simulation 1 — The Cherenkov cone
The angle and the Frank–Tamm yield from Part 1, for any refractive index. Prints 40.2° and about 32,000 photons per metre for ice.
Simulation 2 — Why a cubic kilometre
The arithmetic of Part 2 end to end, finishing with events per year against the size of detector you choose to build.
Simulation 3 — How far a muon runs
The two loss mechanisms of Part 3, where they cross, and the logarithmic range that follows.
Simulation 4 — The Glashow resonance
Two masses, one number: the energy at which an electron antineutrino can make a real W boson on an atomic electron. No plot — just an arithmetic that explains why this particular measurement had to wait sixty years for a detector made of ice.
Limits of these models
The cross-section here is a crude power law, the flux a single E⁻² component, and the detector a perfect square that records everything. Real analyses use measured effective areas, several flux components, Earth absorption and a full simulation of light propagation through mapped ice. These reproduce the orders of magnitude, which is what the derivations claimed.
