Max Planck, Walter Russell, and Pythagoras all explored the pivotal role of frequency in the universe. Planck’s concept of quantization revolutionized physics, while Russell envisioned a cosmic light matrix vibrating at specific frequencies. Pythagoras, too, discovered the harmony of sound. These insights parallel the teachings on rhythm and expression conveyed in “Standing on the Edge of Light,” unveiling the profound connection between frequency, rhythm, and life itself.
