Gravity and magnetic fields ARE telekinesis, the mathematical idea of "fields" is just that, a mathematical concept invented to make calculations and measurements for those telekinetic phenomena.
Yehudi Menuhin So they are non-matter things that effect the world without physical contact. It's still technically "telekinesis". ***** I'm not denying the mathematics, nor the physical phenomena. I'm just saying that it can still technically be called "telekinesis", and making a whole video dedicated to saying "it's NOT telekinesis" seems like a waste of time to me. They still did a good job explaining the physics behind the concept of fields.
Do you even study? Those things aren't telekinesis! Thats like saying a rock hitting the earths surface is earth using it's telekinesis to drag the rock in. Well it's not, thats just gravity, so looking at what I just said, you just gave a kinder garden answer.
I think ***** is right. Fields are mathematical concepts but don't exist in reality. I think its the same goes with Force too. The most clear definition of Force I've heard is that it is a push or pull. Force is not the actual movement itself, and that's why I think it doesn't exist. Also with energy. Am I making any sense?
can you change a light's color just by moving around some magnet in the same direction the light is traveling (this implies changin the frequency variation of the light's field) ? is there some kind of magnet for light ? i think there is something i quite don't get here, if you could explain why i m in the wrong to me please, thanks in advance. (love your channel)
well not really. Light is a wave, its frequency is related to its energy (we call the carrier of the energy photons btw). Magnets interact with other magnets or magnetic fields, magnets also interact with electrons/charged particles or electric fields. However magnets do not interact with photons, and there isn't such thing as a "light field".
If electromagnetic waves are proof that photons exist, then why aren't gravitational waves proof that gravitons exist? Or did I miss understand the part about electromagnetic waves?
I think you misunderstood that part. He was suggesting that electromagnetic waves provide an explanation for how light travels. The idea of the photon is just another interpretation of the same phenomenon (hence particle-wave duality), thought I don't think he mentioned photons in this video. As for gravitational waves being proof that gravitons exist... I'm not well versed enough to speak of this in detail, but logically if one observed a gravitational wave (which is really key - you have to be SURE that you're seeing gravitational waves) and if the gravitational wave were not explained by the existing 'proven' physical laws then one could posit that something else must exist that is causing them and call it a graviton. To 'prove' this in the physics sense would require a repeatable experiment demonstrating that the graviton is there.
+electrocat1 They kind of do. It's why the standard model includes them despite the fact we have not yet "discovered" them. The difference is that we can isolate photons, observe their behavior, and have math to predict their behavior given a set of circumstances. We do not have this for gravatons. So despite knowing they should exist, we haven't "discovered" them yet (just like dark matter and negative energy.).
Santiago Jiménez i know, that's what i was saying. there are radio towers all over the world but they just need to be close enough to your phone in order for a signal to get reached.
The question of electromagnetism has never been explained to me as well as here. This has truly reformed my understanding of the subject. Thanks very much.
Absolutely amazing video, I really like the way this guy presents his ideas. I also never knew understood electromagnetic radiation at such a fundamental level before this. It all makes perfect sense now!
Well of course not, this is a science show and telekinesis isn't real. Surely you understand the relevance of the term telekinesis to the topic though, right?
66LordLoss66 He did explain it, "Action at a distance." We've all seen TK in movies and things, you can imagine that part. But since its not actually a real thing, there's not much about it to explain.
66LordLoss66 Quite honestly, they just showed that what was previously thought of as telekinetic phenomena before the electromagnetic theory matured, really can be explained without the need of such terms as "telekinesis", which are so generic that they are actually meaningless.
This is awesome. I already knew all of this but it was point because they carved the info into my head at school... No one ever explained it to me this way. I hope schools will use videos like these, they help much better than teachers talking for an hour.
Thank you, that you people here exist,making these great videos, bringing more understanding and value to my life. And thanks to circumstance, that I have been born in the rich part of the world so I have the opportunity and technological devices for being able to watch this.
Glad I came across this video. But I have to admit that I don't quite grasp how mapping out the influence of an object in space and naming this map a "field" means that the object isn't really acting at a distance. Am I missing something or perhaps just taking the telekinesis story telling device too seriously?
Each of those field generating things only affects the area of space around it, and it's what's in that space that affects the space leading away from the initial object. So fields are telekinetic in a similar way to dominoes (or a bucket brigade in their example), only by affecting the next thing in line is the original able to exert influence over things that are far away.
You're not missing anything. Of course it's still action at a distance. And so is explaining repulsion by having an electron say to another one "get away from me". Infinite regression. Like explaining gravity by putting a bowling ball on trampoline and watching _gravity_ make the trampoline sag.
the orbital angular momentum of an electron creates an influence in the magnetic field. This "influence" will interacted with all other electrons. its just when you get enough of them in a piece of metal with the same OAM you get a magnet that you can actually play with. Everything is magnetic and is effected by magnetism just like everything with mass is effected by gravity. Its all just fields man.
The sun produces magnetism, everything is magnetic to a degree, its just a field, like the gravitational field or higg's field. Just like everything that has mass is effected by gravity.
Does that mean that an electromagnetic field is basicly gravity on a moving electron or electrons and as it shakes it becomes a wave and thats how light and other things is produced? so magnets are basicly gravity on electrons?
No, gravity is a seperate field. Just like an objects mass affects how it changes the gravitational field, an objects CHARGE affects how it changes the electromagnetic field. A proton has 1800 times more mass than an electron, but an opposite charge of the same magnitude. So electromagentism is similar to gravity, but is "sees" a different quality - charge instead of mass.
But does the field actually exist or is it just a way of predicting how the magnets would interact with an object if placed at a position in the field?
+nobody953 I know that electromagnetism exists. My question is whether it exists as a field. I was thinking it could be manifest as particles which can have their positions estimated and plotted on a grid as a field. Similar to electrons.
+Vaysm A magnetic field is the interaction between two or more particles, there aren't little magnetic particles that flow between two magnetic materials that make up the field, unless you want to get into electrons, which can be behave as both wave and particle, nonetheless.
No other explanation that I have found has been able to help me understand magnetism and electromagnetic fields and whatnot, but this video made me have that epiphany I have been waiting for since I was like 10 O-O THANK YOU.
Jugling is defined as throwing a catching more balls than what you have hands. So two balls with two hands is not jugling, but two balls with one hand is jugling. One ball with no hands is then also jugling but it needs telekinesis to work.
I still have so may questions. Is a field really like a physical thing? because i cant imagine it, and what reallyis pushing away. To have force doesn't someting need mass?
Very nice and well made video. I would have loved to see you mention the zeeman effect or stark effect (changing an atom using electric or magnectic field) and that our heart is producting both of this fields. Which leads to the astonishing conclusion that our heart can change the atoms around us.
My understanding is that translationally (point A to point B), photons (and all ER) always move at the speed of light, c, no matter what. They don't accelerate in the classical sense. however, they have energy not because of their translational momentum, but their angular momentum (think of it as spinning while moving), and this is how it achieves a transference of energy from one point to another when it is emitted from on electron and absorbed by another.

I don't understand it (3:47). Does every kind of electromagnetic radiation com from the oscillations of electrons? I thought of gamma rays as electromagnetic radiation of short wave length that was generated by the nucleus of the atom, but I guess I was wrong... How exactly does it all work?
No the electron was just used an example. EMR can be emitted by all kind of things: Electrons, Atomic nucleus, chemical bonds, lattice vibrations etc. in all kinds of wavelengths. For example an atom that on its own have very few and discrete absorption/emission wavelengths, will have its wavelengths altered when bonding into molecules with other atoms depending on where in the molecule it is locate and what the other atoms are. The bonds them selves will also have vibration(temperature) states that can absorb/emit completely different wavelengths.
yes. basically at the center, the 2 poles cancel each other out. There is magnetism there, but its balanced out, so you don't feel it. its like 1 + (-1) = 0
At 3:42 you drew the electric field of the electron wrong. Negative charge is the sink of electric charge. I get why you drew it like that to easily illustrate the repelling electrons but it's very wrong. Making things too simple gets rid of the beautiful nature of reality.
Oohh I'm so glad I watched this particular minutephysics video. I've been confused by fields ever since I first heard about them. They kind of just dropped into my physics class without any explanation.
But that interpretation goes for other forces too. Gravity can be seen as distortion in 3d space, while Electro-weak force can be seen in as distortion in higher dimentions (String theory I think). What I mean to say that, as long as we are going with the particle model of the universe, if we attempt to fit gravity in the standard model, we have to imagine a "graviton", which, I don't know if we ahve evidence for or not.
Years of reading sciency books, watching sciency videos, and attending science class in school, and this five-minute video finally makes me understand just how the hell a light wave works with a diagram of someone wiggling an electron. Poetry...
Hey Henry, what do you do with all your drawings? Do you save the all? As a visual learner I find them interesting and brilliant. If you don't want them I'll take them off your hands for you.
Actually, that was a pretty impressive mental connection. Matter (mc^2) essentially "sucks in" all other matter towards the apex of the parabola-shaped curve it makes in the spacetime fabric; an effect known as gravity. Does that help at all?
A photon is a concept to help describe how light (and all ER) travels. It can be thought of as a carrier particle for the smallest quantum (discrete amount) of electromagnetic force (the field values shown in this video). It is massless when it is motionless, but when it is accelerated it has momentum (mass*velocity) and energy which is described by E = mv^2 Therefore each photon "particle" must have that wave motion shown in the video in order to carry light. (wave-particle duality)
it works by the principle that like charges dislike each other. So, they push away others with similar charge. They will also pull others of opposite charge. And, that's basically how they work.
And while electromagnetic charges come in two opposite types, we don't yet know of any force that is the opposite of gravity, i.e. a force that repels mass or a different kind of mass that would be repelled by gravity (maybe those were saying the same thing).

The sun produces magnetism, everything is magnetic to a degree, its just a field, like the gravitational field or higg's field. Just like everything that has mass is effected by gravity.

Does that mean that an electromagnetic field is basicly gravity on a moving electron or electrons and as it shakes it becomes a wave and thats how light and other things is produced? so magnets are basicly gravity on electrons?
No, gravity is a seperate field. Just like an objects mass affects how it changes the gravitational field, an objects CHARGE affects how it changes the electromagnetic field. A proton has 1800 times more mass than an electron, but an opposite charge of the same magnitude.

+nobody953 I know that electromagnetism exists. My question is whether it exists as a field. I was thinking it could be manifest as particles which can have their positions estimated and plotted on a grid as a field. Similar to electrons.
From what I know it IS a field. You'll have to investigate further yourself if you want a more complete or complex answer.
+Vaysm A magnetic field is the interaction between two or more particles, there aren't little magnetic particles that flow between two magnetic materials that make up the field, unless you want to get into electrons, which can be behave as both wave and particle, nonetheless.
CALEBMAESTRO My brain cannot reconcile this information with its current model of the universe; time to learn more, lol
No other explanation that I have found has been able to help me understand magnetism and electromagnetic fields and whatnot, but this video made me have that epiphany I have been waiting for since I was like 10 O-O THANK YOU.
Jugling is defined as throwing a catching more balls than what you have hands. So two balls with two hands is not jugling, but two balls with one hand is jugling. One ball with no hands is then also jugling but it needs telekinesis to work.
This was beautifully presented. Loved every second of this video.
AMAZING channel.
absolutely AMAAAAZING.
You guys dispense knowledge in a great way.
That's was the simplest explanation I've ever heard of what a field is 👏
I think this is one of the best MinutePhysics videos
I still have so may questions. Is a field really like a physical thing? because i cant imagine it, and what reallyis pushing away. To have force doesn't someting need mass?
Great video! Loved the subtle mom joke at 4:16 ahah
Very nice and well made video. I would have loved to see you mention the zeeman effect or stark effect (changing an atom using electric or magnectic field) and that our heart is producting both of this fields. Which leads to the astonishing conclusion that our heart can change the atoms around us.
My understanding is that translationally (point A to point B), photons (and all ER) always move at the speed of light, c, no matter what. They don't accelerate in the classical sense. however, they have energy not because of their translational momentum, but their angular momentum (think of it as spinning while moving), and this is how it achieves a transference of energy from one point to another when it is emitted from on electron and absorbed by another.
I finally understand fields... This can help me understand so much more!!! Thank you so much for this video!
tendo-space as the substance or material
and:
contendo : to assert, maintain /shoot (a missile), cast.
extendo : to stretch out.
intendo : to extend, aim, direct, direct one's course, aim at.
ostendo to show, reveal, present, make plain, declare.
protendo : to stretch out.
retendo : to slacken, unbend, become flexible.
tendo : to direct, try, attempt, stretch, extend, present, give.
tendo : to strive, go, heighten, aggravate.
I don't understand it (3:47). Does every kind of electromagnetic radiation com from the oscillations of electrons? I thought of gamma rays as electromagnetic radiation of short wave length that was generated by the nucleus of the atom, but I guess I was wrong... How exactly does it all work?
No the electron was just used an example. EMR can be emitted by all kind of things: Electrons, Atomic nucleus, chemical bonds, lattice vibrations etc. in all kinds of wavelengths.
For example an atom that on its own have very few and discrete absorption/emission wavelengths, will have its wavelengths altered when bonding into molecules with other atoms depending on where in the molecule it is locate and what the other atoms are. The bonds them selves will also have vibration(temperature) states that can absorb/emit completely different wavelengths.
yes. basically at the center, the 2 poles cancel each other out. There is magnetism there, but its balanced out, so you don't feel it. its like 1 + (-1) = 0
countless people have tried to explain this to me and now after watching this i understand
At 3:42 you drew the electric field of the electron wrong. Negative charge is the sink of electric charge. I get why you drew it like that to easily illustrate the repelling electrons but it's very wrong. Making things too simple gets rid of the beautiful nature of reality.
brilliant video, had a hard time grasping it at first but the idea is still settling
Oohh I'm so glad I watched this particular minutephysics video. I've been confused by fields ever since I first heard about them. They kind of just dropped into my physics class without any explanation.
But that interpretation goes for other forces too. Gravity can be seen as distortion in 3d space, while Electro-weak force can be seen in as distortion in higher dimentions (String theory I think). What I mean to say that, as long as we are going with the particle model of the universe, if we attempt to fit gravity in the standard model, we have to imagine a "graviton", which, I don't know if we ahve evidence for or not.
so cool, please get Neil to make more videos!
Years of reading sciency books, watching sciency videos, and attending science class in school, and this five-minute video finally makes me understand just how the hell a light wave works with a diagram of someone wiggling an electron. Poetry...
I think he said It is the shaking of electrons which causes force fluctuations. That fluctuation causes other electrons to shake.
Thank you professor Turok and MinutePhysics!
Why is a Nobel prize winner like a scare crow ? They are both outstanding in their field.....
Hey Henry, what do you do with all your drawings? Do you save the all? As a visual learner I find them interesting and brilliant. If you don't want them I'll take them off your hands for you.
Actually, that was a pretty impressive mental connection. Matter (mc^2) essentially "sucks in" all other matter towards the apex of the parabola-shaped curve it makes in the spacetime fabric; an effect known as gravity. Does that help at all?
A photon is a concept to help describe how light (and all ER) travels. It can be thought of as a carrier particle for the smallest quantum (discrete amount) of electromagnetic force (the field values shown in this video). It is massless when it is motionless, but when it is accelerated it has momentum (mass*velocity) and energy which is described by E = mv^2 Therefore each photon "particle" must have that wave motion shown in the video in order to carry light. (wave-particle duality)
it works by the principle that like charges dislike each other. So, they push away others with similar charge. They will also pull others of opposite charge. And, that's basically how they work.
And while electromagnetic charges come in two opposite types, we don't yet know of any force that is the opposite of gravity, i.e. a force that repels mass or a different kind of mass that would be repelled by gravity (maybe those were saying the same thing).
