Pythagoras, Newton, and Tesla — their lives, their works, and one experiment each you can reproduce. At the far end, the Pythagorean Music of the Spheres.
Your device couldn’t start the 3-D hall, so here are the exhibits in full.
Greek philosopher who founded a school at Croton. His circle is credited with the theorem a²+b²=c² and the discovery that musical consonances follow simple whole-number ratios — octave 2:1, fifth 3:2, fourth 4:3 — binding number, sound, and cosmos.
Stop a vibrating string at half its length and it sounds an octave higher; at two-thirds, a fifth; at three-quarters, a fourth. (The blacksmith-hammer tale is later legend; the string ratios are real and reproducible.)
English physicist and mathematician. In the Principia (1687) he set out three laws of motion and universal gravitation; in Opticks (1704) he showed white light is a mixture of colours. He also co-invented the calculus and built the first reflecting telescope.
A glass prism spreads sunlight into a spectrum, and a second prism recombines it to white. Colour is a property of the light itself, not of the glass.
Serbian-American electrical engineer. He devised the alternating-current (AC) induction motor and the polyphase system that powers the modern grid, plus the resonant “Tesla coil.” He held roughly 300 patents and contributed to early radio and wireless.
Two AC currents a quarter-cycle apart make a field that rotates, spinning a rotor with no contact. The coil is a resonant transformer producing high-voltage, high-frequency discharges.
The Pythagoreans held the heavens are ordered by number: each planetary sphere moves through the aether at a speed set by simple ratios, sounding a cosmic harmony. Honest note: a sound-bearing aether and an audible “music of the spheres” are philosophy and metaphor, not measured physics — space carries no acoustic medium. The true kernel endures: orbital and vibrational systems really do lock to whole-number resonances.
