Summary of Comprendre la physique quantique

00:00:00 - 00:05:00

In quantum mechanics, particles such as photons can exist in two different states simultaneously. This is known as "duality." For example, when a photon is passing through a mirror, it has the option of going through the original mirror or bouncing off the mirror and going through the other mirror. However, until it has a specific path to follow, the photon remains in a dual state, known as "corpuscular."

• 00:00:00 In this video, you will finally understand quantum physics. I'm kidding, but you will finally understand just how important arbiters are. Imagine a tennis player who throws a super-strong ball at a 45-degree angle into a wall with lots of holes. The ball has a 50% chance of passing through a hole in the wall and a 50% chance of bouncing back. This is how a tennis player "gets into the zone." Approximately half of the balls will pass through the first hole and half will bounce back and rebound, like this: Those that pass through the first hole go on to the second hole and have a 50% chance of passing through and a 50% chance of rebounding and bouncing again, like this: The ball eventually rebounds on the third hole and is caught by the player. Now imagine a player shooting a cannon at photons instead of balls. The principle is the same - a photon is a tiny bit of light. However, because photons are so small, we can't see them. When we send photons against mirrors instead of balls, all errors are caught and recorded in a detector. Out of 100 photos taken, 50 will be marked
• 00:05:00 In this video, quantum physicist Max Born explains the principles of quantum mechanics, which state that particles (such as photons) can have more than one possible path through space-time. This allows them to exist in two different states simultaneously, called "duality." For example, when a photon is passing through a mirror, it has the option of going through the original mirror or bouncing off the mirror and going through the other mirror. However, until it has a specific path to follow, the photon remains in a dual state, known as "corpuscular." When a car is moving, for example, you can see the movement of the cars on a photo, but the cars are also constantly moving. In the same way, a photo of a person moving will have a continuous movement, but if you zoom in on the photo, you'll see that the person is divided into individual parts.
