Live neutrino counter
How many solar neutrinos have streamed through your body since the page loaded — roughly 100 trillion every second, and essentially none of them touch you.

Technical notes, short explainers, interactive widgets, and reproducible resources related to neutrino experiments and data analysis.
Interactive
Small, self-contained tools built around the physics I work on — open one and play with it.
How many solar neutrinos have streamed through your body since the page loaded — roughly 100 trillion every second, and essentially none of them touch you.
Open the counter →Drag the beam energy and baseline and watch three-flavor oscillation probabilities evolve, with JUNO, T2K, NOvA and DUNE marked.
Open the explorer →A live sky map and feed of IceCube's high-energy astrophysical neutrino alerts, distributed publicly via NASA GCN.
Open the feed →Secular-equilibrium parent/daughter calculations, nuclide data, and decay-over-time evolution — my own secular-equilibrium package and its radioactivedecay engine, running entirely in your browser.
Open the toolkit →Convert between Δχ² and confidence level / p-value for any number of degrees of freedom (1/2/3σ preloaded), and p-values to Gaussian significance in σ — one- or two-sided.
