Most teachers today are neither good in studies nor good in any of the fields of profession. I used to hate them until I realized that nothing is perfect and so it’s okay if teachers are not perfect. If you think about it, none of the scientists have all the answers and they can’t teach you everything!
This is seriously impressive, one of the best science channels out there on RUclips, you put so much effort into each video. I feel like i'm being sucked into this video.
Your channel has quickly become one of my favorites in this field. as a chronic "But why is that? ... But then why is THAT?" interrogator, much to my parents' and teachers' chagrin, I love your ability to explain advanced physical phenomena in ways that are both elegant, easy to understand and novel all at the same time. I love those "oh it all makes sense now" moments when the penny finally drops, and your channel serves those moments all. the. freaking. time 😍. Keep doing what you're doing, and more of it! 😄😄
This is BRILLIANT!!! I'm a lurker, but I just HAD TO comment this time. What an amazing video. You just explained WHY the universe is made of these particular building blocks in a way that anyone can understand. And the title is so modest. Even "the Element of Life" does not prepare a person for the grand scope of this video! Oh, and that ad segue was absolutely shameless. I love it! Mahesh, thank you!
Your shirt should say "I am" instead of "I am a" because the images read "acute tea pi" which is "a cutie pie" so whole thing becomes "I am a a cutie pie"
i guess.. many would just skip the the two a's because humans tend to read these repetitions only once without noticing any difference. i skipped two 'the's too lol did you notice?
It took *me* so long to figure out the rebus because I thought the cup was coffee. I wish there had been a teabag tag hanging over the side of the cup.
Mahesh great video, as always! Thank you for bringing the joy of understanding things to the masses. Can't wait for the "other videos" about the "stories that are for another video"!😁
Your videos are extremly useful for me . I complted my 12th just 6 months ago . Your every video explains in detail a physics lesson we had in our 11th and 12th . Loved it ❤❤❤❤lesson name (nuclei)
Hello Mahesh! As we all know that your content is unmatched and the way you put it, I think even a child can make a bit sense out of it. But I also think that you should get more traction than what you get right now. Some HI generated suggestions are :D 1. Change the colour scheme of the videos. Don't use black as the background. Use more vibrant colours, but not that vibrant that it becomes annoying. On the colour picker take the colour toward the white part. I think you get the point. 2. Thumbnails! Again use good quality graphics and a better colour scheme. It is not necessary to convey the whole "video topic message" in the thumbnail only. Half goes in the title and the other half in the thumbnail. 3. May be hire a graphic designer/editor if you don't have already. And if you have, then tell them to do a better job. I wish the best for this channel!
"something to talk about in another video" makes me more excited and frustrated. surely we all will watch a 3hr science documentary with such intuitive explanations about such common science questions
I love how you embrace the hard questions for us! My mind was blown recently when I learned that in a nuclear reactor, neutrons aren't blasting uranium some apart like bullets. The neurons have to be SLOWED DOWN to cause fusion. Why? Because with the right amount of energy, the neutron can get captured by the uranium atom, putting it into an unstable state and causing it to split! 😮
I did a PhD in nuclear physics, studying barely bound nuclei in excess of neutrons (maybe you did it somewhere else but distinguishing between "bound" and "stable" worth a video if you didn't), they were of course unstable, but had some peculiarity that gave then ms to s half life (which is very long in regard to the typical decay they should have gone through). That's the kind of content I would ave loved when being lost in the equations trying to make any sense of it. I left that field almost entirely for years, and that video is a nice reminder :-) I greatly appreciate how you can present quite sharp concepts in a very accessible and intuitively understandable form, without bad oversimplifications, and always pointing out where you left aside a complex underlying stuff that the simplification masks. Thanks 🙂
I'll watch the video later after getting time soon...i have come here just to like the video, because i already know, as always, this video is going to be amazing!!❤❤❤
sir we celebrated teachers day today at school and i thought of you . thankyou for being my teacher . sir . i would like to wish you HAPPY TEACHERS DAY !🪻💐💐🌻🌻
Nicely done. I personally think its better to explain the entire thing in terms of energy levels though. Things will always try to fill the lowest energy levels, so why do heavier nuclei have more neutrons than protons? It's simply because the energy levels are not the same for protons and neutrons. The Coulomb force pushes the energy levels apart for protons, making them fill up faster compared to neutrons. And it is because the strong force is short ranged that the effect is only apparent for larger nuclei. It's all the same in the end. Nature will be nature. Explanations are just what we use to understand.
I knew most of the rules and behaviours, but I've never seen them put them together so intuitively. I knew the what, and the how, but never could grasp the why. Now I get it! It's so easy to understand, you should make qm for kids 😊
Wow.. You are truly one of your kind, I spent very long time on Quora to understand the nucleus energy levels, and you have summed it all up in 15 minutes, Your explanation of nucleus energy levels dwarfed every other one I've heard, and yes we want to hear all those stories for another day. All of them. 🙃
I was hoping to see the spacing of the energy levels vary, to show that having additional protons required additional energy (the potential energy from electrostatic repulsion) and to show that as a result, the higher energy levels for protons would outpace those for neutrons, and thus more neutrons would be energetically favorable
Hypothetical: if the ratio of the strength of electromagnetism to the nuclear force (between nucleons) was different, would the point of highest nuclear stability shift from iron-56?
You're an amazing teacher. It's always a pleasure to learn more from you. Please continue making these awesome videos. I also wonder if random decay can be explained somehow. For the decay to happen, does some other preceding action must happen? Do nucleons move perhaps?
Wow that diagram for neucleons energy stability is brilliant!! ❤️✨️😌 Love all the quantum exceptions, and Yes I do want to learn how Alpha Decay works! 😁 Edit: I did learn something new, I didn't know neucleons also had a spin pauli exclusion principle in the nucleus.. It makes sense, but I just didn't know both of them had a spin
My teachers never answered my questions about this but today you have given a super clear answer! I'm feeling so happy that I saw your video. I still have a question: Why don't two free neutrons bind together by the strong force? Many thanks.
[ Video : why is voltage in battery equal to the voltage equal in resistor ] Sir i wanted an explantion on how does the electrons work in a battery works like how does it create a potential difference ?? In this video you said that the electrons are pushed from the postive terminal to negative which is later pushed from the battery into the conducting wire by chemical reactions ...but if thats true how will the battery be netrualised later on ...sir i am a bit confused ...and sir please make a breif video on " what is voltage ?? " Again ..please sir
Normally I don't like "personifying" nature like that, but I guess it's useful for science communication sometimes. Just remember folks, the nature "liking something" or "hating something" is just phrased like that to make it easier to understand. In reality those tendencies emerge directly from the laws of physics, that in turn emerge from the universal constants, and there is no personified entity, will or preference involved.
A very interesting video about the stability of elements and the uniqueness of iron atoms. I think a lot of interesting questions are connected with the stability of the iron atom. The answers to these questions will definitely lead to the discovery of interesting physical effects and the production of iron-based materials with unique properties (it is already possible to consider options from electrical superconductivity and self-healing materials, as there are already significant shifts in these directions) Is there a desire to delve even deeper into the question "what is the logic of nature for the possibility of the existence of such a large number of stable elements"? Regarding the stability of elements, there are three important points: 1) magnetic moments in a proton (14.1*10(−27) J/T) and in a neutron (−9.7*10(−27) J/T) have the opposite sign and different strength of action when viewed separately from each other. And the magnetic moment of an electron (μe = −9.3*(10−24) J/T) is about 1000 times stronger than the magnetic moments of a proton and a neutron. We know that in the Universe, atoms of elements form molecules to obtain a better balance of forces of interaction between the structural elements of atoms. Therefore, the hydrogen molecule (H2) is more stable than individual hydrogen atoms (H). But at the level of the magnetic moments of the proton, neutron, and electron, we do not see this balance in atoms and molecules. I do not understand this and have not yet found an answer to the nature of the formation of the balance with such experimental data for individual protons, neutrons and electrons; 2) Atoms of different chemical elements have different densities, which indicates a different geometry of space filling with protons and neutrons in the nucleus of atoms. The geometry of filling the space also affects the stability of the elements; 3) In nature, individual electrons and protons seem to exist forever, and individual neutrons exist for up to 30 minutes according to available experimental data. 🙏🙏🙏
Very good explanation. It could be further improved by noting that the higher proton energy levels get more spaced than higher neutron energy levels (because of the long range nature of electric repulsion), and this explains why the lowest energy is obtained with more neutrons than protons in heavy elements.
He did such a cool transition to square space, even I didn’t notice when he was saying about square space. By the way how do you actually see atoms and nuecleas?
Hi Mahesh.... Thanks for explaining difficult concepts intuitively. Can you explain why signs for electrodes of electrochemical and electrolytic cells opposite in chemistry and physics? Cathode is positive in Electrochemical cell in chemistry but it is taken as negative in physics, why?
Mahesh sir it seems i only get more questions when i try to find the answers. Now i ask, why is Pauli exclusion principle a thing? Why is it true? Why cant just ALL the electrons stay in the same orbital? This is one of the reasons why i always disliked chemistry, there's so much to be said.
@@DrDeuteron See, it's always something even more complex that explains it and that in itself needs to be explained and then you fall down this rabbit hole of what the hell do i even know?
@@AbhinitPradhan not really. Pauli exclusion principle is applied in quantum mechanics where we just claim particle are indistinguishable (which is more than identical), but in quantum field theory it makes sense that a bump in a field is indistinguishable from an identical bump, and then when you insist fields don't transform information faster than light you get the results--but it's super technical.
Holy shit, I understood that completely... like, I think I could explain it beck even. This guy's reeeaaaaal good! I've never thought about all the *other* forces at play. 😮
I like the concept of your shirt but I have a bone to pick with it. If you read it as is, it says “I am a acute tea pi” but it would be much better if it said “I am acute e pi. For e you could have it say lim n → ∞ ( 1 + 1 n ) n to represent e, but there are better symbols you could use outside of a youtube comment. (I assume you didn’t create the shirt, just making a comment about it lol)
Protons have energy contributions from the strong nuclear force and the electromagnetic force. The Coulomb repulsion pushes the proton energy levels further apart than the neutron levels in heavy atoms. Thus, fewer proton levels need be filled to have the same energy for the next available level.
But how do the neutrons help stabilize the large nuclei? Is it because they increase the distance between protons and therefore the repulsion is slightly lower because of the distance or do they somehow shield the electromagnetic repulsion?
Hey Mahesh, in your video 'why FTL signal breaks causality ' in that video at 10:03 you said that for the observer moving with 99% c the distance of 1 light year due to length contraction will become 3 light months but as you said in the video 'why can't you still reach the speed of light ' that even after length contraction every observer will agree on the distances because the measurement units too will get length contracted. But then why in ur FTL signal video you said that the distance will be 3 light months?? I didn't understand this. plz explain this bro ??plz reply I'm super confused????
I get that you draw the energy levels with equal steps for simplicity's sake, but it does make me wonder if the energy levels are actually the same for both nucleons. Doesn't the positive charge of the nucleus influence the energy levels of the protons more than those of the neutrons?
As a biochemist I will say that is _an_ important element for life ( especially for its redox characteristics) but it certainly isn't _the_ element of life! Carbon knocks it into a hat every time!
Are you going to make a video explaining why the strong nuclear force only acts at short range. Thats another thing I've never been able to understand. Shouldn't its strength drop off by the inverse square of distance, the same as the electromagnetic force?
Hi Mahesh, beautifully explained why too many neutrons can cause instability, i think a good video to make in the future would be to explain The term Enegy states, alot of people toss this term around without understanding it, from my current reserch i been able to understand most time we talk about energy states we are talking about Potiential energy, if you were to drop a ball from a higer place than antoher it has More potiential energy, and this is the same easenially with a eletctron in a atom and when say bonds form when the electrons drop energy state that excess potiential energy they had Has to go somewhere which is why chemical reactions cause energy sometimes, and also cruically Nuclear reactions, for a while i been plagued of where the energy from nuclear reactions comes from most people just say E=MC square and the diffrence in biniding energy is released as energy but that was never consistent with me as somehow the nucleous got more stable because it has more" binding energy"while also realseing energy and was always confused because like it simultaneously has more energy so its stable but also realses ? Energy like what, i now understand jts Bassicly has to do with potential energy shitfs in the nucleous which makes it more stable and the execess energy has to go somewhere, there are still many questions i have on this subject but I appreciate how you take all these Jargon terms like biniding energy and try to explain whats actually happening, i often dislike how science is thought in school and never explaining the why, for a longest time i could not understand Sound waves i could not visualize what a wave was, it took a while to realse sound is Bassicly a dance of kineitc energy and electrosatic attraction, its a physical process which made much more sense than "wave" and the wave like nature is explained by understanding how the process works.
Oh yes!! I totally hear you! Binding energy was a very confusing term indeed. But then I substituted it for , 'blowapart energy' and then it makes sense. It's more stable because it has a higher 'blow apart energy', i.e. it needs more energy to blow apart. That makes sense :)
@@Mahesh_Shenoy yeah lol, well yeah I usually think about the pion exhange that is making the strong nuclear force ,but that's true, was just confused before as to how it could Gain energy (Binding energy) and realse energy in the form light heat etc, but it Bassicly comes down to the fact that binding enegy is influenced by many different factors inside a atomic nuclie so the system as a whole dosent have to gain energy to have more binding energy just needs to be in a more favorable configuration for Electrostatic forces as you explained in the vid or quantum configurations like more Proton to neutron interactions(as these can also exchange Charges pions not just neutral pions so it's strong than same type reaction proton-proton etc) So it can effectively increase without the system as a whole gaining energy.
Sir, at 6:59 When I study about weak nuclear force, books teaches us beta decay process but how a force is related to that decay process? Please Explain Plz Plz 😢
Is it possible for heavier nucleus to still see it with the energy levels ? I mean in your graph you represented the energy levels of protons and neutrons at the same energy for each level but because of the repulsion between protons their energy levels might be more spaced and so it could explain the fact that we have more neutrons for heavier nucleus since the gap between their energy level is shorter right ?

I've never thought about all the *other* forces at play. 😮
I like the concept of your shirt but I have a bone to pick with it. If you read it as is, it says “I am a acute tea pi” but it would be much better if it said “I am acute e pi. For e you could have it say lim n → ∞ ( 1 + 1 n ) n to represent e, but there are better symbols you could use outside of a youtube comment.
(I assume you didn’t create the shirt, just making a comment about it lol)
Love it!!! Yes, I didn’t make but now I have to make a better version 😅
You said in this video: "heavier nuclei are more stable that lighter ones" is that correct or ...?
0:45 Can you not read this graph??
Mostly yes, upto iron!
5:02 Careful, photons are bosons, not fermions. Thus, they do not follow Pauli's exclusion principle. Great video anyway!
Protons, not photons.
@@klikkoleethat makes more sense. Honestly, I still hear photons but the subtitles say protons, so I'm clearly misshearing it
Everything fuses into Iron and decays into Lead. Life and Death in metal form. Nice.
And evolves into a crab
Protons have energy contributions from the strong nuclear force and the electromagnetic force. The Coulomb repulsion pushes the proton energy levels further apart than the neutron levels in heavy atoms. Thus, fewer proton levels need be filled to have the same energy for the next available level.
Could you do a video on an intuitive understanding of the Maxwell-Boltzmann distribution?
Oh yea, it's one of those things that never make sense, until one day it just hits you!! Added to the list.
@@Mahesh_Shenoyplease also make a quantum explanation of covalent bond please
But how do the neutrons help stabilize the large nuclei? Is it because they increase the distance between protons and therefore the repulsion is slightly lower because of the distance or do they somehow shield the electromagnetic repulsion?
Left with a bunch of metaphysical questions
It was so easy thanks... Can you please explain what stability... why does nature prefer one setup over the other
Hey Mahesh, in your video 'why FTL signal breaks causality ' in that video at 10:03 you said that for the observer moving with 99% c the distance of 1 light year due to length contraction will become 3 light months but as you said in the video 'why can't you still reach the speed of light ' that even after length contraction every observer will agree on the distances because the measurement units too will get length contracted. But then why in ur FTL signal video you said that the distance will be 3 light months?? I didn't understand this. plz explain this bro ??plz reply I'm super confused????
you just have to do the Lorentz transformation yourself.
Awesome video! But how about the effects of the metallic bond structure of iron on its stability?
I get that you draw the energy levels with equal steps for simplicity's sake, but it does make me wonder if the energy levels are actually the same for both nucleons. Doesn't the positive charge of the nucleus influence the energy levels of the protons more than those of the neutrons?
After two months, our board exam will held but still I watching your videos mahesh sir ❤
sir i love your all video T-SHIRT can you PLEASE share the link of your shopping website
Lead: exists
Mother nature: I'm so disappointed in you
As a biochemist I will say that is _an_ important element for life ( especially for its redox characteristics) but it certainly isn't _the_ element of life! Carbon knocks it into a hat every time!
I always have this question
Are you going to make a video explaining why the strong nuclear force only acts at short range. Thats another thing I've never been able to understand. Shouldn't its strength drop off by the inverse square of distance, the same as the electromagnetic force?
does the strong force act between two protons? would it be possible to build an atom only out of protons (except hydrogen of course)
Hi Mahesh, beautifully explained why too many neutrons can cause instability, i think a good video to make in the future would be to explain The term Enegy states, alot of people toss this term around without understanding it, from my current reserch i been able to understand most time we talk about energy states we are talking about Potiential energy, if you were to drop a ball from a higer place than antoher it has More potiential energy, and this is the same easenially with a eletctron in a atom and when say bonds form when the electrons drop energy state that excess potiential energy they had Has to go somewhere which is why chemical reactions cause energy sometimes, and also cruically Nuclear reactions, for a while i been plagued of where the energy from nuclear reactions comes from most people just say E=MC square and the diffrence in biniding energy is released as energy but that was never consistent with me as somehow the nucleous got more stable because it has more" binding energy"while also realseing energy and was always confused because like it simultaneously has more energy so its stable but also realses ? Energy like what, i now understand jts Bassicly has to do with potential energy shitfs in the nucleous which makes it more stable and the execess energy has to go somewhere, there are still many questions i have on this subject but I appreciate how you take all these Jargon terms like biniding energy and try to explain whats actually happening, i often dislike how science is thought in school and never explaining the why, for a longest time i could not understand Sound waves i could not visualize what a wave was, it took a while to realse sound is Bassicly a dance of kineitc energy and electrosatic attraction, its a physical process which made much more sense than "wave" and the wave like nature is explained by understanding how the process works.
Oh yes!! I totally hear you! Binding energy was a very confusing term indeed. But then I substituted it for , 'blowapart energy' and then it makes sense. It's more stable because it has a higher 'blow apart energy', i.e. it needs more energy to blow apart. That makes sense :)
@@Mahesh_Shenoy yeah lol, well yeah I usually think about the pion exhange that is making the strong nuclear force ,but that's true, was just confused before as to how it could Gain energy (Binding energy) and realse energy in the form light heat etc, but it Bassicly comes down to the fact that binding enegy is influenced by many different factors inside a atomic nuclie so the system as a whole dosent have to gain energy to have more binding energy just needs to be in a more favorable configuration for Electrostatic forces as you explained in the vid or quantum configurations like more Proton to neutron interactions(as these can also exchange Charges pions not just neutral pions so it's strong than same type reaction proton-proton etc) So it can effectively increase without the system as a whole gaining energy.
Sir, at 6:59
When I study about weak nuclear force, books teaches us beta decay process but how a force is related to that decay process?
Please Explain Plz Plz 😢
Still, how more neutrons in helium will be unstable. I didn't understand proton and neutron energy levels
Is it possible for heavier nucleus to still see it with the energy levels ? I mean in your graph you represented the energy levels of protons and neutrons at the same energy for each level but because of the repulsion between protons their energy levels might be more spaced and so it could explain the fact that we have more neutrons for heavier nucleus since the gap between their energy level is shorter right ?
