Pune Scientists Building ATOMIC CLOCK

Indian Scientists at @IISERPuneSMC are working on a strontium atomic clock that would be one of the most accurate in the world. This is work from Dr. Umakant D Rapol in whose lab this experimental setup is being built.

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.

You are one of the rare Indian Channel on KZbin which are actually focusing on science. In west such channels like Veritesium is common. Thank you for doing this.

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

[@anubhavarya3894]

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🙇‍♂🙇‍♂

[@GareebScientist]

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

[@DipankarNath]

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!

[@GareebScientist]

Thank you Dipankar, yes had to tone down the complexity 🖖🏽

[@angryhusky2467]

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.

[@angryhusky2467]

Since school days we were taught like this.

[@observantmagic4156]

I still don’t understand tbh. Are we measuring oscillation of the light photons because of the atoms?

[@angryhusky2467]

@@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.

[@HM-cw8im]

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?

[@abheeray]

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!

[@GareebScientist]

yes i remeber buying encyclopedias , only source of info since no internet

[@uniqueone4097]

I searched the whole internet in search of proper explanation of atomic clock ,But never Ever I found a Video .

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

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.

Atomic clocks are used in various applications, including scientific research, navigation systems, telecommunications, and satellite communication. Among Internet being a good example of an application that benifits from the use of Atomic clock '! Though there are some drawbacks like : 1. Cost: Atomic clocks can be expensive to develop, maintain, and calibrate due to the intricate technology and specialized components required. 2. Size and Weight: Traditional atomic clocks were bulky and required specialized laboratory setups. However, smaller and more portable atomic clocks have been developed in recent years. 3. Power Dependency: Atomic clocks typically require a stable and continuous power source, making them sensitive to power interruptions or outages. 4. Complexity: Operating and maintaining atomic clocks can be complex due to their intricate mechanisms and the need for skilled technicians with expertise in atomic physics. So, despite these drawbacks the exceptional accuracy and reliability of atomic clocks make them invaluable for numerous essential applications in modern era !👍
