Quantum physics

Retinal cells are like a grate which try to discretize the world of waves. The brain also behaves like a grate to understand and split the world around ourselves. When scientists don't exactly understand why photons behaves curiously in the classical double split experiment, they just forget to think that everything in the universe is a wave, included the grate, included the small part called "photon", included the result of the experiment analyzed by the eyes and the conditionned brain of the scientist. So, photons are not special, they are waves, like everything in the entire universe. And the result of the experiment shows interference patterns (like waves' behaviour).
