The background is a Game of Life: click to drop a glider.

Four fields

From algorithms to living things.

Computer science, physics, chemistry, medicine: each field has its colour, and its experiments.

3D render of Cas9 and its guide RNA on DNA, atoms as spheres on a light blue background

3D Launch the experiment

MedicineGene editing

CRISPR-Cas9, cutting DNA

The 3D animation from the video, replayable and hands-on: Cas9 looks for the PAM, opens the DNA, and cuts. Pause, hide parts, move them, then put everything back.

The space station above the Earth; behind it, the predicted paths of a thrown object, in colour, drift apart orbit after orbit

3D Launch the experiment

PhysicsOrbital mechanics

Where does an object dropped in space go?

An astronaut throws a bag or a CubeSat from the station: straight line, Clohessy-Wiltshire, Kepler, or a calculation with air and a flattened Earth — four ways to predict its path, which drift apart orbit after orbit.

A ray-traced black hole: its black shadow, circled by a thin ring of light, and the golden disc of gas whose far side appears bent up over the black hole

3D2D Launch the experiment

PhysicsGeneral relativity

General relativity, hands-on

Place masses on spacetime, launch particles, spin an orbit into a rosette, bend light around a black hole, compare clocks from the ground to GPS and watch a gravitational wave go by.

Computer scienceCellular automata

The Game of Life

An infinite grid, two states, a four-line rule: run the most famous constructions, from the glider to giant computers, and watch them live.

See, touch, check.

01Watch
A video starts from an announcement everyone has seen, and digs into the science behind it.
02Explore
Every topic opens a 2D or 3D experiment: change a parameter, move forward step by step.
