Existence is digital with analog override ...

1801 and 1900, years forever changing how man views reality, were the start points of all things relating to the world of computation. The first was Thomas Young's double slit experiment showing light to be both a wave and particle and in 1900, the introduction of quantum mechanics showing, without question, that existence is digital with analog override. :)

It easily explains quantum, a key concept of quantum mechanics.

It explains the history of quantum theory. As the first step, it  examines  the origin and meaning of quantum.

The table of contents for this video is as follows:

1. The meaning of the era of quantum mechanics
2. Without quantum mechanics, there would be no computer - modern civilization is quantum civilization.
3. Why is quantum mechanics difficult- Even genius physicists such as Richard Feynman and Niels Bohr said it was difficult.
4. Quantum mechanics is difficult because it goes against common sense and intuition.
5. The first step in understanding quantum mechanics is to understand the quantum. Examine the origin of quantum and its physical meaning.
6. One of the backgrounds of the birth of quantum mechanics was the problem of blackbody radiation.
7. Examine Max Planck's quantum hypothesis, which established a quantum hypothesis and sowed the seeds of quantum mechanics.

Young's experiment was based on the hypothesis that if light were wave-like in nature, then it should behave in a manner similar to ripples or waves on a pond of water. Where two opposing water waves meet, they should react in a specific manner to either reinforce or destroy each other. If the two waves are in step (the crests meet), then they should combine to make a larger wave. In contrast, when two waves meet that are out of step (the crest of one meets the trough of another), the waves should cancel and produce a flat surface in that area.

In order to test his hypothesis, Young devised an ingenious experiment. Using sunlight diffracted through a small slit as a source of coherent illumination, he projected the light rays emanating from the slit onto another screen containing two slits placed side by side. Light passing through the slits was then allowed to fall onto a screen. Young observed that when the slits were large, spaced far apart and close to the screen, then two overlapping patches of light formed on the screen. However, when he reduced the size of the slits and brought them closer together, the light passing through the slits and onto the screen produced distinct bands of color separated by dark regions in a serial order. Young coined the term interference fringes to describe the bands and realized that these colored bands could only be produced if light were acting like a wave.

Again, existence is digital with analog override. :)
