- The framework in which quantum mechanics and special relativity are successfully reconciled is called quantum field theory.
Heres how you can easily understand Quantum Field Theory.

In theoretical physics, quantum field theory (QFT) is the theoretical framework for constructing quantum mechanical models of subatomic particles in particle physics and quasiparticles in condensed matter physics. QFT treats particles as excited states of the underlying physical field, so these are called field quanta.
In quantum field theory, quantum mechanical interactions among particles are described by interaction terms among the corresponding underlying quantum fields. These interactions are conveniently visualized by Feynman diagrams, which are a formal tool of relativistically covariant perturbation theory, serving to evaluate particle processes.

This is for dummies and I still don't get it... Damn, I need a "QTF for dummies for dummies" version
his English?
Everyone who is here.Thanks for watching!
Thanks for animating + explaining such interesting stuff, it really matters 👍
Quahntasy - Animating Universe I have precious little knowledge about quantum physics or any physics, but found this video most enlightening. However, the music seemed to distract and over-rule your voice at times. Great narration, sir. Thank you.
This is the best brief explanation of QFT... all the best for another videos in future
Awesome! I took optics in college and learned a little bit about particle vs wave. Also I really like your summary lol
Nice one. I like the general style, editing and music. The "You are awesome" was a tad too much for me though ;)
All I can give as creative advice would be to maybe change things up once in a while in the future. Take real-life footage (fruit or real vending machines for example) when you do metaphors. And maybe there are some other CZcamsrs or animators around who'd do a collaboration. ;)
Thanks Necro.I think I should work on more videos before approaching any big guys for collaboration.Thanks for advice :)
IMO that's the wrong approach. Chances are that you'll get easily overlooked by big channels regardless how famous yours is. Science channels mostly don't have a huge amount of subscribers. If you see a video of someone and you like what they do just try to ask those for a collaboration (right then and there).
The best point in time for that is when you already have an idea and a script for a video and are ready to go at any time.
Can u send 2D or 3D image of quantum field plz?(example:electron field,up-quark field)
What are left 16 machines ?
18 particles? According to wikipedia there are 17 particles (en.wikipedia.org/wiki/Elementary_particle).
Am I missing something? Or have they found a new one?
Thanks, this is a great explanation.
Excellent summary! Thanks. Any book suggestions for non-physicist students?
Its always "Feynman Lectures of Physics Vol 1 and 2"(book).Its not really lectures but intuitive approach to physics in layman terms.
i have watched dozens of videos on QFT. This is the only one that states outright that there is ONLY 1 field (of a given type) for the entire universe and that all particles of that type exist in the same field. so many more questions arise from this, for example, can two electrons exist in the same space (ie pass through each other), or do they merge? why do they repel? so many more questions than answers.
But the fact is that this video has NOTHING to do with real QFT at all. The simple harmonic oscillator is high school stuff.
@@jacobvandijk6525 are you telling me particles don’t have faces? C’mon man!
@@cslloyd1 Hahaha, no! They have faces and sometimes take the bus.
Wow, thanks so much you explain so clearly.
New Video remembering Stephen Hawking's Work on Black Hole Entropy and Hawking Radiation (animated).
Do watch it!

THanks!
Now. Can anybody tell me how this is different from the luminous ether theory?
Where does the 'energy' come from?
It's always existed
good effort, subbed, you worked hard, hello from India.
Nice one, brother!
Thank you for your awesome animation skills!! (Physics is much better this way)
Thanks for your explanation. You are awesome.
Thank you ...
I just listened to a a physicist explain it. I must say you was much better. I guess they must explain it with more fancy words, so it can sound serious.
yay, that's a good explanation!
damn you nailed this!
Great video
Good job
Nice.. subscribed..
Wow, it is a good video. But, I would suggest you to be in your natural accent, it will sound quite good.
why don't they explain the particle/wave duality like this from the beginning? it would solve so much damn confusion..
you got a nice talent keep up the good work but work on quality
I wonder how much photons cost? ;)
You are awesome too!!!
where is dat energy coming from ? take an iron cube what u see is a solid made up of atoms whuch are made up of particles which are according to q.f.t are fluctuations in their respective fields . but how do they appear as a solid in the first place?? to be a particle they need energy but how did they got energy
Too much music noise
I felt like I was 7 but thanks for such an easy to understand introduction to QTF xD
*sigh, only theories...if only there was a microscope strong enough
How would it be possible? How can you look at a fundamental particular that has the size scale of ONE photon when looking at things needs billions of those photons to be captured by the instrument?
At that scale, microscopes are useless and will always be. Especially if these particules are near to the size of a point, which means no size at all.
All we need is to formulate a theory which doesn't contradicts the macroscopic reality and which is valid enough to make predictions.
If you have one of those, your theory is as valid as any other one.
Good vid!!! This is an invitation to see an interpretation of the mathematics of Quantum Mechanics as a geometrical process of energy exchanges that forms what we see and feel as the passage of time! In such a theory the Planck's constant ħ= h/2π is a
constant of action in the process that forms the continuum of time. Heisenberg's
Uncertainty Principle ∆×∆p×≥h/4π represents the same uncertainty we have with any future event with the future unfolding photon by photon with each new photon electron coupling or dipole moment! With classical physics representing processes over a period of time as in Newton’s differential equations. We have a universal process of energy exchange with an emergent future relative to the atoms of the periodic table (us) with ‘time’
being a creative process not just a process of decay or entropy.
your videos are for those who have some understanding in modern physics...not meant for dummies
Next Time I will try to explain stuff more simply.Thanks for comment though :)
accent makes it too incomprehensible
I understand it and I'm not even a native speaker. Also, you can use subtitles
I like it when the background music is so loud that I can hardly understand what you are saying ;)
Quantum field is a fail theory,it doesn't explain relation of quarks with magnetism.
Yes it do, do some research
it's cute
Loose the music, interfering with understanding your English.
Why don't you make a children's book. I think your cartoons are charming.
very nice! would you like me to shout you out on my channel? I like to do science videos as well!
Hey,that would be awesome .Thanks!.
roti thandi ho chali aa i cant watch the rest of the video
are u talking on purpose like dat or is that your way of talking?? i didnt understand what you u arw saying mostly because of that stupid background music
Dumb Hippie - "If we are all fields.. then this MUST mean I can influence the physical world with my MIND!" All joking aside, I do notice the whole "everything is fields" thing when I am tripping and I "guess" when you can feel someone staring at you, but that in no way means that I think you can "control the physical reality, see into the future" via "spiritual means" that is sloppy and unscientific, magical thinking..
James Livingston I believe it's possible. If we are all as humans made up of matter, and matter simplifies down to energy and that energy simplifies down to frequency which is just information, we along with the air around our skin and beyond are all just wavelengths vibrating at different speeds sending different info. Now this is where I get to why I believe we can manipulate these waves. When a electrode is not being observed its is not matter it is frequency, but when a scientist looks at the electrode through a microscope, that electrode takes form to solidify the particle, but when it's no longer being observed again back into frequency it goes. I t has long been believed in esoterics that when in a deep meditative state, deep enough that you forget about you, your body, your environment, time, and space and become pure awareness(frequency) you can then create. And all this quantom field stuff that they didn't have back then(or maybe they did) backs that in some people's mind. But to each their own, believe what you want that's all it is a belief.
James Livingston You dirty hippie haha
how am i awesome? u dont even know me..
