Nhi karunga kyuki gareeb scientist ab ameer hogya hai aur heart nhi deta
Bhai kya aap mere ko koi rocket science se related book suggest kariye na please❤🙏
namaste sir mera app sa sawal hai ke hamare desh mein kya koi opticarl computer /computing ka research ho raha hai. Please batia in one video please
Bhai next video , HAL and GE ki jet engine deal pe bnana. Will it be beneficial for india or it will make us totally dependent on US, and giving the dream of Made in India Jet engine. There not much talks in media on this. So, if you could research and make video on it.
Bro can I join you, I am a BSMS student at IISER Pune. Biology background
You are one of the rare Indian Channel on RUclips which are actually focusing on science. In west such channels like Veritesium is common. Thank you for doing this.
Ye i only trust him and science to technology...
also pardon my grammatical mistakes. I typed that hurriedly. before anyone points that out...
@@studytime2570 the role of language is to get the massage across , do not care about the grammar police , they are unemployed people with an anger against everything. Science FTW
Veritasium doesn't go too much into science
There's one more, Nimbus Education.
Detailed explanation of ISRO Rockets, spaceships, upcoming missions, And also Physics, Science and Tech
I worked on the Cs fountain clock at National Physical Lab, CSIR New Delhi about a decade back. Specifically, I had designed part of the fluorescence detection circuit for the expanding Cs atomic cloud that eventually maps out the beautiful Ramsey fringes. This video and your explanation brought back a lot of memories and joy. Thank you.
damn, thanks a lot, aukad ke bahar ki tareef
Proud of u sir
Pranam
Bro to be honest you are raising the bar for scientific temperament in India. I am sure that may be just 1% watching this video, but surely this video will inspire Indian students to pursue research on these cool topics instead of running behind money and pursuing courses like CSE just for sake of higher packages. I certainly aspire that one day most of modern and futuristic technologies will be home grown in India which Dr. APJ sir dreamt about. And you are playing a vital role in it by bringing out these hidden gems in India. Hats off you GS🙇♂🙇♂
thats a big responsibility and thank you fr your words, i just learn something new and cover it , maybe few get inspired along the way
underrated comment
For that govt also should support research and development if they only don't support how the hell will these take place first govt should develop them then only these can happen
true..
Logically said
As an alumni from IISER Pune and having worked/interacted with them during undergrads really makes me proud!!
What do you do now
You cleared one of my biggest doubt about atomic clocks in a really simple way.😮😮😮
All this time I was thinking it was the vibration of atoms when specific frequency was thrown upon them. Didn't know it was just opposite.
Since school days we were taught like this.
I still don’t understand tbh. Are we measuring oscillation of the light photons because of the atoms?
@@observantmagic4156 we can make a clock using light of particular frequency and wavelength. But how can we practically know what the wavelength of light we are using is? Through calculations we know that strontium will absorb 698nm wavelength light the most. But practically how do we check it? This machine helps us to isolate that particular light of that particular wavelength. We throw laser light of various wavelengths on the strontium atom and the one that is absorbed by strontium atom the most is the 698nm wavelength light. Now this isolated laser is sent to an electronic device that generates clock signals using it.
So basically this video shows how to exactly test the frequency and wavelength of light we are going to use to make an atomic clock.
Ab mai kuch bhi comment karega to heart milega🤣🤣🤣
@@angryhusky2467 That was really good explanation. Thank you
Frequency comb which you mentioned is probably one of the most important component as that is what is used to measure the frequency of the laser. Hope you cover that next time! And good to see Umakant's lab doing so well, his lab has progressed quite well since he first joined IISER Pune! The explanations were really amazing, it is very difficult to actually convey laser cooling to people let alone talk how atomic clocks work. Keep up the good work!
Thank you Dipankar, yes had to tone down the complexity 🖖🏽

Awesome Umakant's lab team. Nostalgic to be proud of a junior who is doing cutting edge fundamental research. Proud of you UDR.
Need more Indian RUclips channel like this thankyou sir
I'm working in this kind of lab in Singapore. Good to see people working about it in India.
One of the best Indian channels on science. Love your content. While the viewership numbers may not balance out the effort and thought that goes into making a vdo I'm sure you'll grow much larger if you keep this up. Best of luck!
Saw this video for the first time . I am excited to how research is happening in india and hats off to the sir and the other people who prepared such an apparatus. Thank you for bringing this to us
Great animation...tough topic! Still wonderful. That is some advanced quantum lab. Hydrogen masers are another set of base apparatus for maintaining clocks.
yea tough for sure, this video likely wont do well, but i enjoyed making ti so much, lot to learrn
Super cool work and video❤
I think what was missing is the use case, There are many but most importantly its used for GPS.great work by scientists and you👍🏼
this is a ground clock, will be used for national time keeping, if made for that standard
and yes should have gone into it, already overwhelmed
Please! Bro Make Video On ISRO Join NASA Artemis Accords 🚀🇮🇳🤝🇺🇸🚀
m not interested in that topic sorry, its just signing of some treaty type deal, it doesnt mean india has joined artmis mission, jab science and engineering side se kuch ayega tab dekhenge ,
@@GareebScientistOkay! Bro 👍
@@GareebScientistyou are very Anti NASA bro 😂😂 (just kidding 🙃)
@@GareebScientist bhai tu bara ghamandi hai re, padh likh le high level ki padhai
Hi please make a video explaining India's future possible participation in ISS including Indian astronaut in iss
I searched the whole internet in search of proper explanation of atomic clock ,But never Ever I found a Video . This Channel made me feel that India can't be behind in any field than others and It was One of the Best explanation that cleared my 70 percent doubts and first Time I understood procedure and I can't beleive that it's in IIser Pune .Thanks For Your Explanation and You deserve minimum a millions of Subscribers .
You are one of the best YTubers in the country man. Iv been following hour channel for some years. Best of luck to you. You deserve millions of more subscribers
Hats off to your commitment to spread knowledge across this nation with language that is easy to digest, I do watch Vigyan Tv India as well and you both have been so so good!
Your parents should be proud of you brother !
It's an amazing video! Please keep making more!
I didn't understand 1 part - how can the transition frequency of Strontium help devise a clock? What periodic oscillations are being monitored to define a second?
Thank you for bringing amazing content and explaining them most simplistically. I recently started following your channel.
Explaining science concepts with graphics lowers the age bar to grasp such concepts and helps increase the scientific temperament of the younger generation. In our days, only sources available were poorly drawn B&W representations and heavy text books written in a language that often needed picking up another! Even understanding a simple orbital structure or energy states of electrons became extremely mundane to a level where the goal ended up being studying it to pass an exam.
Keep up!
yes i remeber buying encyclopedias , only source of info since no internet
You are one of the Best Channel, who shows Scinece.
It's good to show case Indians Labs and their efforts. 🎉
Superb video, Bhai !! You've explained the concept of Atomic Clock like no other.
As a 12 class student i can confirm that : kuch samajh nhi aya lekin sun ke acha lga 😅 . I don't know much importance of this video but may be in future i will 🥲. Thank GS 😍
Wow! What a channel.. Very few channels of India exploring science.. Keep up good work
i can assure you that I enjoyed it a lot gaining the knowledge about that. Hope to see more such videos
Great one! Kuddos for the animation part ❤👏
Thank you! 😄
Next level experience, plz continue this type of content. I much lntrested in this. We need this type of content, really amazing ❤❤🤩😍
I always wanted to create a science based youtube channel like vertasium, nile red , action lab but due procrastination and overthinking to create good videos. I failed, but seeing you it motivates me to start again. Hopefully, somewhere in the future, i will be making videos with you.😁
Good channel just started watching the video in last 2 days. It has got me back to my learning days. Creats curiosity to start learning again
itne din baad mje finally atomic clock ka working and significance pta chala. suna hua tha par pta ni tha kya h iska kya use h. maza aaya
Great to see this underrated video and the progress of India
One of the most informative video. Learnt new things which I never heard of.
While loading atoms from oven to main MOT, they are using a 2D MOT along with a zeeman slower, really really doing precise stuff. I’m really impressed. Very less people load atoms with a 2d MOT, and with a ZSlower it’s really rare. Proud. Great job. Keep it up..!!
Whoa, kafi mast video tha. Hats off to you 🙏🙌
Amazing video and excellent explanation.
Keep up good work.
👍
Phenomenal work 🇮🇳
Looks like you're a fan of Mr. Musk
any problem??
You are truly talented. Great work you are doing every day.
How do they measure number of cycles (oscillation)?
bro where were you, why didnt I find your channel early. Anyways I am glad that I atleast found it now. Your content is amazing. Keep it up
Nice brother thank you for doing this... i always watch your videos... and you are the only source that i get information about science...😊🙏
Hats off to you and your team sir . I sincerely hope each and every child and youth in India that is interested in science follows your channel 🙏🏻🙏🏻
Team nahi hein sir. Akela hi hun. Thank you 👍🏼
Really nice explanation.Thanks a lot for the hardwork
Extremely good video aur batane ka tarika bhi ,,,hope karta hun ki channel grow kre aur iss TOPIC pe jo v apne skip kiya h aap uske liye ek saparate video bnaenge👌👌👌VANDE MATARAM
make a short video or a long video on India signing the Artemis accords and its implication on ISRO and our future missions.
Amazing video, learned something new ,
Thank you for the amazing content as always
Hi. Good job on making this video!
I had a question, if frequency of the lasers is so important here why is it set on trial and error method only, like how do they know if the atoms are in right temperature? Shouldn't the absorption spectra change if the temperature is not right?
Tnk u. hindi mai itna complex topic explain krne k liye always ❤❤
one question ?
why we are cooling it down and forming lattice of Strontium atom and why cant we use metal direct ?
IAT results gonna be out on 3rd July
I have chance to take admission in IISER Pune for a BS-MS degree
if anyone reading this comment after that
just remind to reply haha 🫡
And wish me luck!! 🤭🤭
best of luck 👍🏽
@@eukaryoticorganism8883 thnks
Keep working hard bro. We will always support you 😊😊😊
Thank you so much 😀
Very well explained!Thank you!
Indians need to follow good wire management at all levels!
Really insightful video gs, i would love if you cover more such topics related to research among indian academia.
I will try my best
Do you think the bases of the material matters when trying to build a different formation clock or the basis of the atmosphere in between the material
great explanation...Now only I understood the role of atom in atomic clock....
In which software you do the 2d animations ??
तुम बहुत अच्छा काम कर रहे हो भाई! हमें और चैनल चाहिए जो भारत में अनुसंधान को जागरूकता दिलाते हैं।
Thank you, people happen to resonate with my interests
Brother thanks for bringing this invention to our attention. Now we can proudly say that yes we can do anything. Now we are not less than anyone.

Please make video on jet engine (GE-HAL deal ke around) & Please explain all (if not all then important) the components of jet engines & how many components we indian already have indigenous & how much we need to develop....that is hot topic & interesting too!!
Can this atomic clock be utilized in our Navic satellites like the recently developed and deployed IRAFS - Rubidium atomic clock?
Or is it completely different in size, specs and function and can only be utilized for academia and physics research?
I was wondering, if we localise the position of an atom to such a precise location aren't we violating the heisenberg uncertainty principle. Like if see in double slit experiment, narrower the slit, the wider the photons arrive at the screen?
Thanks very much.
Your lucid way is absolutely fantastic.
thank you Manish !
The selected atomic lattice wavelength absorption range is locked onto a laser via trial and error, described laser clock frequency is used to denote each second.
will my watch receive the time signal to set time?
We are proud of u sir
Keep going
We are also working hard
Jai mata di
Jai bharat
Hello sir.
I've a question.
Why space satellites and other such equipments are covered in silver / chrome/ gold colour wraps?.
Any scientific reason?
Is it possible to cool through BEAM or Small Microwave
Salute hai yr aap jaise logo ko and humare scientists ko and gov.. ko
Really interesting man. I appreciate your work.
When I see these labs and their animations I can't help but feel like this is like real world Minecraft where you built new automated/manual devices for different purposes...
awesome work bro. thnq for making this videos
Gyan ki daridrata sarvocch daridrata!!! Cheers Garibium for showing me an actual atomic clock. Impalpable made fact today!!! Nahin Gyanen sadrasham!! Dhanyavaad
Wow! Such research is happening in non-IITs, I thought they were the concentration of such things, glad to see it's not the case.
IISER ko kam smjh rha h kya ??😂😂 IIT technology m h IISER science m h no1
@@jigsaw2281wahi toh IIT are best for engineering and IISER and IISC are best for pure sciences but with an exception of IIT kanpur
Is fraction, traction & Gravity in process. What i can understand
Can I got atomic signal reception over my casio multiband watch once/twise a day from this power plant when completed ?? 😉😎
Keep doing what you do! Blessings 💞
but why a particular element for locking the frequency??
freq comb par ek video bana dijiye, you are explaining well and good
Great job... Keep up👍👍🤘
Finally some cool physics coming out of India. Being a cold-atom physicist, I really appreciate your effort. ❤
Great video, brother
More power to you brother 🎉
This video should be much bigger than this. Actually we need more explanation. By the way good job👍
current standard for atomic clocks are rubidium based, especially used in space for GPS
THANKYOU SO MUCH FOR YOUR EFFORTS AND DEDICATION SIR
Thanks for the Video
Appreciate your efforts 😊
Really nice and simple explanation!.. 😀
Strontium hi kyun use hua? Aur atomic clock is kya use hai?
Love your videos and explanations!
I have a question hope someone clears me
Question is How we can use that frequency 698nm or oscillations corresponding to this frequency to set or determine the duration of 1 second???
Based on atom transition frequency. Because it is universally fixed
Great discussion
Very informative video.. Thanks bhai🤗
How to extract Garibium?
Ha content bahut unique and rare hai
Very good informative video, appreciated
❤ your videos
*Please tell us about yourself* 🙏🏻 It will provide motivation to Sc. Students like us
