The three-body problem stumped Isaac Newton and Henri Poincaré—the latter even laying the groundwork for chaos theory while trying to solve it.
A major breakthrough came in 2000, when Alain Chenciner and Richard Montgomery uncovered the famous figure-8 solution—shown in clip 4.
In 2013, Milan Šuvakov and Vladimir Dmitrašinović expanded the picture further, identifying 13 additional families of solutions.
Each clip represents a true numerical integration of Newton’s law of gravitation, F = G·m₁m₂/r², using equal masses—no tricks, no shortcuts.
It’s a reminder that mathematics dating back to 1687 still holds deep and unexpected surprises.

Scientists have created one of the most detailed 3D reconstructions of a human cell (eukaryotic cell) ever produced.
This groundbreaking model, often termed a "Cellular Landscape Cross-Section Through a Eukaryotic Cell," combines data from X-ray tomography, nuclear magnetic resonance (NMR), and cryo-electron microscopy to map molecular structures in extreme detail.

In 1923, aircraft were used to release titanium tetrachloride as a smokescreen to conceal ships at sea. When exposed to moisture in the air, the chemical produced a dense white cloud—made up not just of smoke, but fine droplets of hydrochloric acid and titanium oxychloride.
