I’m 54, a physicist who’s spent decades unraveling the universe’s secrets—from quantum quirks to cosmic scales.

If you’re in your 20s and passionate about physics or science, please read this: 1. Build your mathematical foundation early. Calculus, linear algebra, and differential equations are your tools—master them like a craftsman.
2. Experiment relentlessly. Theory is great, but hands-on labs teach you the chaos of real data. Start with simple setups at home.
