the unit “Pascal” (Pa)—used to measure pressure—was named after Blaise Pascal, a 17th-century French mathematician and physicist who studied how pressure behaves in fluids. But here’s the twist: Pascal’s experiments with barometers and mountain altitudes helped prove that air has weight, a radical idea at the time!

And get this—pressure affects the boiling point of liquids. That’s why water boils at a lower temperature on a mountain and at a higher temperature in a pressure cooker. So next time you’re cooking at altitude, blame the physics! 🌡️⛰️🍲
