Sadi Carnot was born 230 years ago today.
In 1824, while studying steam engines, he discovered a limit that no technology can overcome:
No engine can convert all heat into useful work.
This insight became the foundation of thermodynamics and understanding of energy. Carnot died in 1832 at just 36 years old.

How fast does something spin? Angular velocity ฯ measures rotation rate in radians per second. It's fundamental for understanding everything from planetary orbits to centrifuges to quantum mechanical angular momentum.

Mercury is the only metal that remains liquid at room temperature because its atoms form unusually weak metallic bonds.

Niels Bohr cracked the atomic code with this equation describing electron orbits in hydrogen. Though superseded by quantum mechanics, it beautifully shows how discrete energy levels arise from quantum rules.
