- In 1911, a physicist named Ernest Rutherford conducted an experiment that changed our understanding of matter forever.
This video will take you through Rutherford's famous alpha scattering experiment, which led to the discovery of the atomic nucleus.
We'll explain how Rutherford and his team made their groundbreaking discovery and what it means for us today. You'll learn why atoms, the building blocks of everything around us, are mostly empty space. We'll also discuss why this discovery was so shocking and why it's not often discussed in textbooks.
Whether you're studying for a science test, a teacher looking for classroom resources, or just curious about the world, this video is for you. So, if you've ever wondered about the nature of matter, or why atoms don't collapse into themselves, join us on this journey into the heart of the atom.

I was very anxious about doing the role play. A part of me is screaming inside saying, "Noooooo..". Do you want me to do more or not? 😰
It was very useful and carried the message very clearly.
yes yes yes!
Sir you are great teacher ^_^ ....
I think that's what kept us engaged throughout ....it was really good sir
yes!!!!1
This man is Khan Academy with more fun skits and excitements that makes learning physics so enjoyable. Hat off to you, my man!
Great Stuff. Would love to see you follow this line of thought and study further towards the splitting of the uranium atom.
My grandmother told me that one day when she was at high-school the teacher came in with a serious expression on his face an announced to the class that "they have split the nucleus of the atom".
Serious stuff.
Woah! Can't imagine the feeling of hearing this live!
THESE ARE THE GREATEST LECTURES ON PHYSICS I HAVE FOUND!!!
PLEASE CONTINUE CREATING THEM.
No disagreement from me.
I like the idea of the professor having to wing it in front of the class just as a new discovery comes 😂. The humor of the reality that those who are teaching us also are constantly learning. 😂
Your chanel is so underrated
Thanks, buddy!
I remember learning about Rutherford's experiment in high school, but I never really understood what his hypothesis was, or how he reached his conclusion. Now I do. Great video.
Hey! Sarbajit here. This is by far the best video on this topic. Finally, we have someone who focuses more on the science, and the essence of it; not just teaching for some competitive exams which most people do :3
Beautiful video, I really think such videos should be made more often.... I too teach physics in a small institution in my locality... And always have been amazed how beautifully you introduce a topic in your video.... Such an enthusiastic way you have to introduce something mind blowing
Thanks, buddy :)
Fantastic nice and easy way of Explaining a lot of physics. I will love to listen more.
A must watch video for all students studying the atomic structure 🎉🎉🎉
Yep truly a gifted teacher....long live the teacher. Simply the best.....
Problem 2-19 in "Electromagnetic Fields and Waves" by Lorrain & Corson (2nd Edition) discusses the stability and resonant frequencies of Thomson's Plumb Pudding Model.
An example titled "Thomson's Problem"in "Modern Electrodynamics" by Zangwill discusses the mechanical stability of the Thomson model, Problem 3.24 discusses a similar geometry in the context of macro-ions common in biological environments.
More of this, please! You do a great job of communicating the mixture of wonder and irony that went into a lot of physics.
You should do one about how Schrodinger stumbled into quantum mechanics by making a wild guess in frustration
Oh yes! Max Planck too!
@@Mahesh_Shenoy that’s right! Got it mixed up in my head 🤣
More videos about the atom, please! It’s amazing how so many branches of sciences intersect on this topic. Great storytelling!
Such a beautiful video......
The way you explain the concepts of physics is just impeccable
Great stuff!!
Some topic suggestions:
1. Electron orbitals -- how they are kind of like static shells, but also move at the same time without radiating energy
2. Noethers Theorem
3. Spinors
Loved the video. You bring joy and enthusiasm to physics.
Thanks :)
Congrats on 40k.. You are doing really well, gonna reach 10x this in the blink of an eye. I wouldn't dare suggest "improvements" but I wouldn't mind you explaining all the nobel prizes either. My math is so-so but at lest mention it, like you did coulombs law, so that I can find the formulae and try it at home. Thanks, keep up the great spirits! (and please don't become dependent on distracting ads, such a shame)
I've been following your Physics videos for a while now, and I really appreciate the way you simplify complex concepts for us viewers. Your content is both educational and entertaining!
I wanted to suggest a fascinating topic that I believe would make for a great video series - the concept of mass in particle physics. There's a common misconception that the Higgs boson is solely responsible for giving mass to all particles, and it would be fantastic if you could delve into the nuances of mass in your next videos.
As I've learned, the 'main' mass of physical objects, especially within atomic nuclei, arises from the strong force interactions between quarks and gluons, which contribute to the mass defect of these particles. However, the mass of fundamental particles, such as quarks and leptons, is a complex interplay of factors, including their intrinsic mass (due to their interaction with the Higgs field) and the kinetic and potential energy associated with their interactions (like the energy stored in the strong force for quarks).
Clarifying this distinction would be incredibly enlightening for many of your viewers and help dispel the common misconception surrounding the Higgs boson. Keep up the great work, and I'm looking forward to your future videos!
Hey Braulio, thanks for the suggestion. This sounds like an incredibly fascinating topic. I think Veritasium has already made a video on that.
But, I can immediately see it as a Higgs boson vs E = mc^2 (or Higgs vs Einstein) or something like that. That would be a good spin. :D
@@Mahesh_Shenoy❤
You are a fantastic educator. Thanks!
Yes please more, more, and more quantum mechanics, especially about standard model and it's properties.
Mahesh, you’re killing it with these videos man…I’m loving them…please continue making more!!!
I personally love your teaching style and you have an absolute gift for imparting knowledge. Thank you friend.
You make a nice show from this science knowledge. The videos need a lot of effort to make. I love them mostly because you take every little step to the next question to ask and then present the answer. This gives the audience some time to start thinking themselves! Great teaching!
This was a very good video. You did a great job illuminating how Rutherford was able to use his data to see that the nucleus *had* to be compact (very compact). That was the key insight of his work. So, great job, man.
I love this guy. ❤
Freakin’ Awesome Mahesh! Your passion is infectious and your roll playing is seriously wonderful. Thank you for making these videos.
I appreciate you and your work. Especially because these long takes are so difficult and you just roll with, and keep in, the slip ups.
Keep doing it all! Your candor is much needed.
I think you could take this same conceptual approach to historical narratives and you would do quite well. I'd love to hear some of those conversations you'd play out.
bro the joy you have while explaining and making people understand the wonders of physics is extremely datioactive. your joy radiated to me and made me soooo excited to study further. i hope more people get to know how awesome you are. cheers man and have a good day
sir, you helped me a lot and your videos are the driving force behind whatever understanding i have about science. thankyou for reviving the spirit of questioning and critical thinking in me! you are the only physics teacher that has taught me the spirit of science. i admire your work and am eager for more!! thank you very much for all these great intellectual videos!!♥♥♥
Loving your work! Keep making the videos for us.
This dude got me through highschool single-handedly when he was at Khan Academy. Now as I'm into college, he haunts me again.
I'll be giving you a huge shout out from the biggest possible audiences that'll ever encounter in my life, if happened.
Thank you so much for your videos. It really helps me to understand hard-to-grasp physics intuitively. Hope you will always keep making videos like these.
The most underrated CZcams channel forever 😢
Thanks, Santosh 😊
Great stuff. I have a Masters in Physics and Ph.D. inAstronomy, and I still learn something from every video!
I greatly appreciate your work in creating understandable and entertaining explanations of physics. Your obvious enthusiasm is refreshing - there are already too many experts with an ‘authoritative’ teaching style - learning and discovery is, and should be, joyous. Thank you!
Absolutely loved this, easy to understand, fun..brilliant👍🏾
I enjoyed watching this as much as you enjoyed making it. Great!
Rutherford was one of the greatest experimental physicists of all time. Up there with Faraday to be honest. I have to say that the work was done by Geiger and Marsden but Rutherford was absolutely key....
Apparently, it was Geiger who discovered the large angle ‘abnormality’. And the experiment planted the seeds to create the Geiger counter.
Science history is amazing!
Really great videos..not just entertaining but genuinely informative and substantial...bravo!
Another great video thank you. Looking forward to seeing the next one
man you are so much underrated .... please dont stop uploading
Your video is really fun and inspiring. You deliver knowlegde by telling stories. And I cannot wait to watch your new videos explaining the birth and evolvement of quantum mechanics.
Just wondering... could negative particles have been used instead of alpha particles?
We needed heavy particles. I think that’s why we went with alpha. The only other choice was beta.
@@Mahesh_Shenoy
Okay sir. I just finished watching the video, so I would say please make more videos on quantum it's one of the topics that fascinates me the most!
The radio active substance emits alpha, beta and gamma simultaneously. So how did Rutherford filter out beta particles.
Super explanations and history lessons. Enjoyed much.
Very interesting. Thank you for elucidating this history...
Fantastic job! Please, do continue!
What an explanation with the excitements. Love this man...keep making more.
Really excellent video and thought provoking too.
Beautifully explained. Never found a video so exciting to explain atomic models!
Bravo…. Continue creating great videos. It will be shared with my students.
Thank you for expanding my knowledge in a more complete way by explaining the basics within the very same videos instead of just taking them as given.🙏
Your explanations of atomic physics are fantastic. I have read a few of Feynman's books for lay persons about electromagnetics and you are better since he tries to avoid the math (in the ones I have read) and you are brave enough to combine both! Do more!
Please keep making more of this series❤
There was one major flaw in Rutherford's experiment. I am somewhat surprised that you didn't point it out. The alpha particles produced by the radium had a complete spectrum of energies. Any alpha particles of the "correct" energy will b embedded in the gold foil, thus charging it up and repelling the low-end energy alpha particles back at the ZnS screen. Also, it seems rather odd that they knew that alpha particles came from substances (such as radium), yet they thought they could be emitted from a "plum pudding"? There's something very odd about all this.
Very underrated science channel
Thanks, Buddy!
Loved it, please make more videos like this!
I have always believed the best way to teach Science is through its historic perspective you have done that brilliantly by showing time line of the discoveries and how the theory had to be modified to accommodate new data. Well done a brilliant lecture.
A very good video! Well done! You are a good teacher! Love your enthusiasm.
Nice way of explaining. Love it
Thank you Sir for this video! FINALLY ONE interesting video about all the failed models for atomic structures !
Oooo! But now we need to ask what does "Empty" mean? What does "Size" of an atom mean?
One answer ---> two more questions. Will it ever end?
Your visualization of size of nucleus vs atom is about the best I have ever seen.
Excellent explanation and presentation. Thanks
Glad YT recommended your channel. Good video my friend
plz keep making such videos!!👍
One of the best video 💥
Amazing video! You rock!
I love that the planetary atomic model is just a convention. It's based on literally nothing, other than; "well the planets orbit around the sun, maybe electrons orbit around the nucleus."
And that model stuck for decades, hell even a century. When I was in school I was taught the planetary model. Though our teacher told us that it's not accurate but much easier.
Great Stuff. Would love to see you follow this line of thought and study further towards the splitting of the uranium atom.
Loved this! So helpful for a non-scientist to understand!!
"Hey Rutherford what's up" was awesome😂
I really like your sense of humour. Plus educational content is great!
Great video, contineu with your journey on Quatum...Cant wait for your next vidoe
Thanks for sharing! ❤
It'll be so helpful if you clear some confusions about this topic, I mean about atom and it's structure.
It's hard to think the distribution of electrons. What is the actual diagram of electrons distribution around a nucleus.. Please explain in a video.
_Your student from Bangladesh 😊
fun science education video, plus awesome dramatization. Keep it up
I never understood the alpha scattering experiment but now I can say I do...all the context really helps..as to why it was needed what was before...really good work...btw is there a follow up video to this one...?
My kids are enjoying your video and learning has become so fun for them.
Thanks for your videos 🙏🏼
Wonderful video. Just found you on Utube. Watched three in a row, and understand electron (apparent) quantum "spin" and electromagnetic attraction and repulsion relating to Coulomb's Law and Relativity.
thank you for the videosir
It's so fascinating how one model *evolved* from the other, I'd always imagined the scattering was so strong Rutherford considered an elastic colision and infered the probable size of tge nucleous using the ratio between the scattered and non-scattered particles, kinda like Dalton's model as well!
But now thinking about it, that assumes charge is carried by a solid particle, which isn't a very good assumption to have when you don't know about protons yet! Having Coulomb's Law as the source of the scattering is really interesting, I hadn't thought of it through that lens be before!
Thanks a lot for your videos, you're the best!!
You are explain so well. Physics looks interesting
In my own experience words often go in one ear, through my empty head, and come out the other ear. Thanks for the explanation.
Excellent lesson
Great video again 👏🏼👏🏼🎉🎉.I knew most of the contents of the video but i watch this video because of your way of communicating any science topic. Why don't you start a course on how to communicate science ? If you can pls 🙏🙏. Hoping to get notification of next video of this soon .
That's such an encouraging comment, Bablu!
Awesome video. I don't think many people are aware of the stadium model of the atom. That always blew me away. 🙂 I hit the subscribe button. 👍
Amazing set of videos I happened to find on YT. Would love to see some coverage on general relativity which is my favorite topic :)
excellent 👌
Good job!
Good shit keep it up dude👍
Wolfgang Pauli foreshadowing at the end...
Great video and please, definitely make more of these! Including the skits!
The Werefrog have shared your videos with a friend, and we agree, you are fun to watch and explain it well.
Great job 👏
I like your video and your way of describing things. Congrats! I found years ago this percentage of empty space in the atom's volume. I'm curious to see how and with what you will fill this emptiness.
Fields.
@@dananorth895 Could be, indeed. Still, the term field is very ambiguous and unclear, it is mostly a math term not a real one. However, I'm waiting his way of thinking to see how will fill it.
Absolutely, do more! I was shocked when I looked at the likes being so relatively low... Then I saw this was only 6 days ago... So yeah, I'm hanging on a cliff bro, bring me more!
Great work by the way 😊
Please make more of high schoold physics videos! And also about CHEMICAL BONDING, MOLECULAR STRUCTURE.... it'd be fascinating to study from ya!😌
Yes yes and yes!!!
18:17 How did you get to that percent?
If the nucleus is 100000 times smaller than the atom, then
Let x = size of atom
size of nucleus = y
We know y = x/100000
Space left in atom = Size of atom-size of nucleus
= x-x/100000 = 99999/100000 x
or 0.99999 of the original atom
to get the percentage, we multiply by 100
Therefore empty space = 99.999% of the atom
That’s the radius. For 3D space, we need to calculate the volume ;)
Ok nevermind, the 100000 times smaller is the diameter!
So volumetrically the nucleus is 99.9999999999999% smaller. Damn the nucleus is so much smaller than i realised!
@@Mahesh_ShenoyWhoops, ya, just realised that!
@@TejasIsAmazing It's inconceivable!!!!
I enjoyed ur video. There is an easy to learn hand through hand magic trick. It would have fit perfectly in this video or future ones.
Great video. You must do some videos on quantum stuff❤
Excellent explanation, thank you. But I wouldn’t miss the role playing if you were to drop it. And moving the microphone out of the way would be a plus. Thanks again!
