Thousands of interactive maths and science notebooks contributed over two decades, each one a single slider-driven idea.
Opens in a new tab. We do not control this site and it may have changed since we catalogued it.
Wolfram Demonstrations Project sits in Science Toys under Learn, and we have it filed as coffee break — five to fifteen minutes of proper attention. It reads as brainy and clever.
Simulations you can meddle with: orbits, evolution, chemistry, cellular automata. Understanding through interference rather than through reading.
Ben Eater's flocking simulation with the three rules exposed as sliders, so you can break the flock deliberately.
A stocked chemistry bench in the browser where you can mix reagents and get it badly wrong at no cost.
Interactive models of what complexity science likes best — epidemics, flocking, synchronisation, forest fires.
Home of Conway's Game of Life — pattern archive, wiki and a board for setting your own cells running.
An explorable on how ideas and riots spread through a social network, with the contagion thresholds under your control.
A graphing calculator good enough that people make art with it — type a function and drag its parameters about.
Build a circuit and watch current move through it as coloured dots, with an oscilloscope available on any node.
A toy about synchronisation — a few hundred blinking dots that agree on a rhythm with no conductor anywhere.
