Fluid mechanics is notorious for being one of the toughest subjects in physics and engineering. But here’s the secret: From the blood pumping through your veins to the air flowing over a plane’s wing, from the water coming out of your faucet to the weather patterns on the news—you already experience fluid mechanics every single day.
