If E=mc² and E=hf, then mass = frequency! Sir Roger Penrose explains why every massive particle is an ultra-precise "little clock." By blending Einstein’s relativity with Planck’s quantum law, he shows the existence of mass implies a specific, insanely high-frequency vibration. At the fundamental level, matter isn’t just “stuff”; it’s rhythmic energy keeping perfect time. Credit: TheInstituteOfArtAndIdeas
