So, how else does the hologram analogy relate to the structure of the universe?
First, similar mathematical laws can be applied to many natural phenomena at many size scales. Consider the vibration of strings and musical intervals, which were studied by the Pythagoreans, and the correspondence with electrons in an atom. A vibrating string will have a fundamental pitch associated with the entire string moving back and forth in one motion. But the string will also vibrate in a more complex manner, with waves and nodes associated with integer divisions of the string length (one-half, one-third, one-fourth, etc). These integer division nodes create the higher harmonic frequencies which are not as loud as the fundamental pitch, but contribute to how the string sounds – the timbre. The electrons in an atom also have a “harmonic” structure with discrete levels associated with the energies of the electrons in orbitals surrounding the nucleus, usually electromagnetic energies in the visible and ultraviolet. Schrdinger used the analogy of a vibrating string to develop the w
