The Gaussian-School of Higher-Arithmetic (1831, updated 2022) ; tutorial #10. 

Quantum-Relativity (qr).

Quantum-Relativity (qr) is easy, it is just simple arithmetic. However, the arithmetic that you have been taught is NOT the natural arithmetic of Mother Nature. You need to start again with Gaussian-School arithmetic.

If you would like to see Nature through the eyes of Gauss or Maxwell, then think exponential, stop writing the exponential base in a larger font than the index, the index IS the number, the base is just the exponential environmental decryption value. The decryption of the exponential number x is e^x and that is just a simple flat number.
