Ross Rhodes guides us to the limit of the Shrine of Objectivity. This cult meets its match in the quantum realm (the very very very tiny). The Double Slit Experiment is the arena where objectivity meets its tragic end. The First Person Singular, for the first time in science's history dethrones the reigning monarch, objectivity, and takes Its rightful place as the Kosmos's foundation. But first, let's review motion in media, waves; their radiating movement; wave interference; wave patterns. Alas, the sound on these videos is poor; a small price to pay considering...
Illustrated presentation of quantum mechanics & the double slit experiment. Wave-particle duality meets information theory. And it's fun!
In Part 2 we look at particles and the nature of light. Particles are tiny bits of matter. They rest unless acted upon by other particles. They stay in motion unless acted upon by other particles. When they collide, they bounce off each other. Is light a wave or a particle. Newton says a particle--maybe. Hook says a wave--maybe. Thomas Young wants to decide and the Double Slit Experiment is born in 1801.
When particles are smashed the smallest unit one arrives at is the quark. Collections of quarks, atoms, molecules can be held in the hand, have temperatures taken and weighed. How do particles go through slits?
Now we fire particles one at a time through the double slit. We notice the photographic plate at the back collecting a wave pattern. What is going on?
Now we count particles one by one going through the slits. We have detectors at the slits telling us. Where the particles hit the wall, a particle formation forms. We then take the detectors away and thereby are left clueless as to where the particles go through. Now what's this? There is now a wave pattern again!
If a particle goes through a slit heading for the back wall does it hit the wall if no one is looking?
No.
Observation creates what we see at the back wall.
