Sir agar agar mass energy another form hai to mass should be in negative in absolute temperature kyuke in absolute temperature vibration kinetic energy is zero while potentian energy is still there which is negative.So mass should be negative

30 mins into this lecture and I thought teleportation is actually possible since mass is a cluster of energy arranged systematically, we can transfer the energy from one place to another. I think this is how Devatas in the Hindu religion used teleportation. Amazing! how Hinduism and Buddhism have the most of the answers to life. WOWWWW!!!

Mass is a energy that all energy exhibits,, and that's what sprituality says..... that's why we chant mantra..... sound is vibration, a energy.... which can impact you and me and everything positively or negatively.🙏🙏🙏
Teachers r ocean of knowledge ...but delivering that knowledge in such a way that each nd every student understand is really a tough task nd than with sub. Like physics .... Tq sooo much sir for teaching us ..u r the best teacher i ever got on u tube 🙏♥️
We know that E=mc^2 i.e mass can be converted into energy that means hum log energy ke kisi vhi form convert ho sakte hai.. Into light into current into heat..
@@U_known_ of course ...why not...for heat we have to burn ourselves ...then use that heat to rotate the turbines and get electricity ... Unless you are talking about brain waves energy and stuff like that ....
Actually that's a very deep question you just talked about. See, mass is just a concept used to define the energy a body contains. Energy is simply work done, and work is done by the 4 fundamental forces we have in nature. Of course, as the gentleman suggests, you can convert yourself into heat energy by burning yourself, but by doing that you will no longer be alive. The chemistry between your atoms would be changed completely.
Respected sir, I am commenting on t = 22:51 Total energy of an electron (as you pointed out) is sum of its Potential energy is due to force of attraction by Nucleus and its kinetic energy due to motion around nucleus. Both of which depend upon the mass of electron. This appears like, mass of a body depends on its mass. (By body I mean electron in this case.) Please point out the mistake in the above argument. Thank you Regards Ishaan P. S. Anybody who can point out the mistake please do so by replying to this comment or emailing me. Thank you

Thank God Jeetu bhaiya exists in real world also !!!!!👍👍👍😊😊😊
49:56 1eV is 1.6×10^(-19)J. so 1J will be (1/1.6) ×10^(-19)eV
Sir when u explained that mass is a property of energy I got goosebumps
U r really awesome sir what a great explanation n understanding 👌👌👌
yeah so did i
That means you never heard something really shocking,if u r getting gooesbumps in this shitty knowledge 🤔🤔😂
@@varunmahajan858 it's not that I didn't know about it, it's just that only sir can explain and make me realise things that most other teachers didn't 🙂
@@varunmahajan858 really shitty knoledge
Sir ye to sachhe ka jaadu ho Gaya ....mtlab mass.doesn't change Vali theory to poore hilll gae he sir ....thanks sir itne achhe se itne baade baat Ko samjhane ke liye ....🙏🙏🙏
Feel of physics is interesting that alakh sir can give
This is one of my best class i ever had.
30 mins into this lecture and I thought teleportation is actually possible since mass is a cluster of energy arranged systematically, we can transfer the energy from one place to another. I think this is how Devatas in the Hindu religion used teleportation. Amazing! how Hinduism and Buddhism have the most of the answers to life. WOWWWW!!!
sahi bola
This man is living legend 😍😍😍
Yep I agree
I totally agree with u

@@rohinisharma810 one lecture is remaining for Nuclear fission and Fusion
Physics wallah web series dekhi our ye video sabse jyada popular hua usme btaya...... so check krne aa gya🤘🤘
This lecture literally blew up my mind. Sir, if einstein ever met you, he would be proud 'cause there is someone to continue his legacy.
If physics is art then the artist is Alakh sir ❤
sir i am in kota and regularly listening to your vedios and i feel that the way you make me understand ,no one can do the same in a such confident way.............. i will be meeting you soon in prayagraj soon after my neet -ug exam.......you are really a great person thanks you so much........
sir it is true that your videos are lengthy but bar bar ek topic ko choti choti video dekh kr smjhna and bhul jane se aacha h ki aapki video ek baar dekh le kbhi nhi concept me dikkt aayegi...thanks a lot for helping sir 🥰🥰🥰🥰
The best teacher I have ever seen...👌
So much lucky to have you.
Lots of love and respect for Alakh Sir from 🇧🇩🇧🇩

Mass is a energy that all energy exhibits,, and that's what sprituality says..... that's why we chant mantra..... sound is vibration, a energy.... which can impact you and me and everything positively or negatively.🙏🙏🙏
U r so hardworking sir.... Upload lecture at 1:05 a.m. ....we really respect u sir😊
He had start uploading before 4 hrs uploading becomes complete on the 1.5 am
Sir raat ko 3 baje dekha maine aapka lecture poori neend udd gayi hai.
Itna interest kisi bhi topic ko padhne me nhi aaya aaj tak.
you know its amazing that millions of students were studiying from one teacher
1.6 *10**(-19) comes in divide at 49:34
Sir ap jese teachers nasib walo ko hi milte he warna kon itne ache trike se sumjhata he bhagwan apko khushiya de
Teachers r ocean of knowledge ...but delivering that knowledge in such a way that each nd every student understand is really a tough task nd than with sub. Like physics ....
Tq sooo much sir for teaching us ..u r the best teacher i ever got on u tube 🙏♥️
Hii@jyotika
We know that E=mc^2 i.e mass can be converted into energy that means hum log energy ke kisi vhi form convert ho sakte hai..
Into light into current into heat..
Ha...to photoelectric cell main to wahi hota ha
Solar heater
@@ankithere423 ya but I'm talking about humans that humans can also turn in any form of energy
@@U_known_ of course ...why not...for heat we have to burn ourselves ...then use that heat to rotate the turbines and get electricity ...
Unless you are talking about brain waves energy and stuff like that ....
Actually that's a very deep question you just talked about. See, mass is just a concept used to define the energy a body contains. Energy is simply work done, and work is done by the 4 fundamental forces we have in nature. Of course, as the gentleman suggests, you can convert yourself into heat energy by burning yourself, but by doing that you will no longer be alive. The chemistry between your atoms would be changed completely.
Respected sir,
I am commenting on t = 22:51
Total energy of an electron (as you pointed out) is sum of its Potential energy is due to force of attraction by Nucleus and its kinetic energy due to motion around nucleus. Both of which depend upon the mass of electron.
This appears like, mass of a body depends on its mass. (By body I mean electron in this case.)
Please point out the mistake in the above argument.
Thank you
Regards
Ishaan
P. S. Anybody who can point out the mistake please do so by replying to this comment or emailing me. Thank you
I wish mujhe alakh sir ke lectures dekhne ka idea 11th me aagaya hota toh aj mai government medical college me mbbs pursue kar raha hota

Is it possible to not fall in love with Physics if you're being taught by this legend? He researched, practised and performed! ❤
yes it is
not possible@@ShubhVerma184
That tatoo explains sirs dedication and interest towards physics
Goshh I'm starting to love modern physics and ofc I luv this man

I had so many misconceptions about the theory of relativity but sir's explanation cleared all my doubts. you are great sir👏👏👏👏 Hats off to you!!!
The best video of pw sir I have ever seen in physics..literally no one has explained in such depth..god bless u sir
The connection he has with the students is more stable than BINDING ENERGY!!
30:00 - M. defect
No one can explain this concept better than THE GREAT ALAKH SIR😍
49:18
A small mistake by our big-hearted
teacher
1J = 6.24 x 10^18 ev
=> delta E = (1.67 x 10^ 27) x (3 x 10^8)^2 x (6.24 x 10^18) ev = 931.5 Mev
Correct I find that
I haven't learnt physics cause, Alakh sir made it felt❤
