'Feynman's Integral Formula' for pinpointing 📍 Quantum Particles w/Brian Cox #quantummechanics

Prof. Brian Cox at ABC Science explains how it is possible to know the maximum end position of a particle moving from Point A to Point B with the help of 'Feynman's Path Integral.' He explains how you consider the particle moving along every possible path from A to B, and Feynman's approach is to do that mathematically by adding up a set of quantities with each possible way, known as the 'Quantum Dance.' In the end, he explains why we need to ask some questions in Quantum mechanics to truly fulfill scientific experiments.

Imagine you have a particle at one location, and you want to know the probability of finding it at another location later on. Traditional quantum mechanics involves solving complex equations, but Feynman had a different way of thinking. So instead of following a specific path, Feynman considered all possible paths the particle could take from the initial point to the final point.


Example:
Let's say your particle is like a tiny ant moving on a tabletop from point A to point B. Instead of taking one straight path, the ant could take many different routes, zigzagging, looping, or even doing a little dance on the way.

Action:
Now, imagine that each possible path the ant takes has a certain "dance score" associated with it. This "dance score" is what Feynman calls the "ACTION." It's just a number that describes how the ant is moving along that path.



Math:
Feynman's idea is to add up the ACTION "dance scores" for all possible paths. Each path contributes to the total based on its "dance score." Some paths might contribute a lot, others a little, and some might even cancel each other out.

Probability Amplitude:
The total sum of all these "dance scores" gives you a number, and when you square that number, you get the probability of finding the ant near point B at some future time.

Interference:
Imagine some paths make the ant's dance better in sync, while others make it more chaotic. This interference between paths creates a pattern in the probabilities.

Real-World Analogy:
Think of it like taking a walk in a park. Instead of following one straight path, you explore all possible routes. The more scenic or enjoyable paths contribute more to the overall "enjoyment score."

In the quantum world, particles explore all possible ways of getting from one point to another, and Feynman's approach involves adding up these contributions to understand the likelihood of finding the particle in a particular place.

The thing about Feynman was he was an expert in getting down to the core principles of things especially explaining in depth principles

I have used the Feynman technique in school and have found it to be an effective way to learn and understand new concepts.

[AaronAcheneje]

I hope one day I become so knowledgeable about these things. For now, I'll try to brush up on my math

The probability having all these hairs at 60 as Brian Cox Is the same to find another intelligent life in the Milky Way

Where does the energy go in the double slit experiment where waves cancel out ?

[davidpile]

This is quite a universal truth. I watched this and replaced each occurrence of the word 'particle' with 'wife in a car' and everything he said held true. Even the "anything that can happen will happen" has been experimentally proven by my wife in her car

[varshavaghani]

Dont know about Feynman. Can anyone tell me what has that guy done? Never studied Maths and physics seriously so dont knoe about him

[ernestopulido]

So its like predicting the future of where someone's locations will be next?

I have no ideawhat im asking, i probably didn't understood s***t😂

[javadfardaei]

It is impossible to write one-dimension static equation for thee-dimension of nature that it is changing constantly.

[ExoticCheff]

Ok thats just it? Feynman's Integral Formula

[artigeeks]

Am I the only one who didn't understand 10% of this?

[alexsuited]

So what he is saying is do alot of math and eventually it should appear in the vicinity? Or it's there already or over there it's on the otherside of the galaxy all at the same time. It's when you observe it that it shows itself. Cool 😎

[xtgcsvo]

Almost like the universe is more powerfully chaotic then humans could ever hope to understand.

[JRock]

Just because it CAN doesn’t mean it WILL!!!

[ВикторПоплевко-ет]

This is how british people actually sound like when they talk

[rickishit]

Of course a hacker who cheated the Matrix knows how to explain this.

[harris]

just sounds like goboldy gooch to me. never was that good at maths, i get by on money but that is as far as it goes

[jonathanplastow]

Because there is zero time in the Quantum realm.
