Quantum Field Theory Explained in 2 Minutes

Показать описание
Quantum Field Theory is a theory in physics that describes the behavior of subatomic particles like electrons and quarks. It's based on the idea that these particles are actually just excitations, or vibrations, of underlying fields that fill all of space.

Now, I know what you're thinking - "Sunny, that sounds pretty complex." And you're right, it is. But here's the thing - the math behind Quantum Field Theory is incredibly accurate when it comes to predicting the behavior of these subatomic particles. In fact, it's one of the most successful theories in all of physics.

But there are some things about Quantum Field Theory that don't quite jive with our intuitions about the world. For example, the theory predicts the existence of particles that we can't actually observe directly, like virtual particles that pop in and out of existence.

And there's also the issue of the infamous "measurement problem" in quantum mechanics, which Quantum Field Theory is a part of. This is the idea that when we observe a subatomic particle, we affect its behavior in a way that seems to defy classical physics.

So, to sum it up, Quantum Field Theory is a powerful and accurate theory that helps us understand the behavior of subatomic particles. But it also raises some profound questions about the nature of reality that we're still trying to grapple with.

Make videos with more elaborate explanations, like Science Asylum, Parth G, Arvin Ash, Up and Atom or Fermi Lab. Videos should have something solid as take away.

the simplicity in your video is amazing ♥...I want to see you explaining quantum mechanics in the next video.

Hay i have a doubt on my mind... Here u r saying that particles r treated as waves but then how the second quantization works?...

I wish you would have elaborate on the term "observed"

What is the motivation behind having a quantum FIELD theory? Why fields?
