As a PhD student in ultra cold atom field, I felt so much when watching this talk. Dr. Ketterle is the best at nearly all aspects as a physicist, lecturer and group leader, and what Dr. Pritchard have done for him, was even greater. I can only image what a great person Dr. Pritchard is for giving his whole achievement to Dr. Ketterle.
👏👏MIT has been extraordinary and so vital in modern physics. I truly appreciate and value this information they regularly crank out and share. Wolfgang & David are a great team.
Matter wave-packaging made of time-timing making sync-duration. Yes, and modeled on Professor Susskind's Black-body Superspin Superposition-point Singularity Conception. "Needs no introduction" or further comment.
Water is mother of elements. Solid, liquid, gas, electricity, ultrasonic vibration, plasma and again same reverce cycle invisible plasma, ultrasonic vibration, electricity, gas,liquid, solid. You are absolutely right.
Was hoping for something more on condensed milk. Like to stick it in the fridge, 277.15 K, and eat it from the can with a spoon though laser tweezers sounds like a delightful option
Can you arrange for a consultancy project with every physics prof or max being so famous. People will see and some doctors will tell. Such an awesome video there is a theory that mutual marketing gets max likes for physics videos which gets certain number. You tube is great. There is a hierarchy of subjects. Sociology offers best physicists. Wolfgang ketterle is greatest.

continue to watch lectures like this, google scientific terms you don't understand, and if you don't understand something in those descriptions, google that too. If you truly want to understand, repeat, repeat, repeat.
Atoms are not waves. They are particles. We know now that laser beam can be used to "cool" down atoms with the aid of an external magnetic field. How? We know every atom has its own unique nucleus structure, a particular type of atom with a specific configuration and strength of external magnetic field, its nucleus structure would flex in certain unique way with the just right intensity of dynamic photons per volume per time of a laser beam, the exchanging of photons by the nucleus where it could (as we knew now) dissipate out more photons than the ones that it absorbed from the laser beam. Subsequently, its nucleus has fewer photons than before. Thus, it has been cooled down. Of course, not any laser beams or any external magnetic field, the same strength and configuration of external magnetic field and a particular type of laser beam will have different effects on different types of atom. In other words, no one size fits all scenario. We know also know that magnetic trap can temporary trapped some atoms (and we believe those atoms are energetic too with sizable amount of photons) when the magnetic field has been shut off, those atoms can now move freely away from one another (probably due to the repulsive forces of their nuclei against one another and of course, they also have their own respective "initial" momentum) in which as they drifting away while dissipating out their photons that such dissipated photons formed images of "waves" (that you called interference pattern). But if you look carefully those are hardly "waves" or "lines" . In reality, those jagged "waves" or "lines" are constructs of pixels of photons that "landed" there per time depending on the availability of photons. It is wrong to assume (by you) that those "waves" or "lines" are those atoms that behave somewhat like waves. The atomic tweezers clearly shows that nucleons within a nucleus are charged particles. As a result the nucleus structure would flex in certain orientation and configuration under the influence of a particular electric field. Then again not all atoms would experience the same effect under a similar configuration and strength of electric field and laser beam. Basically, the unique flexure of nucleus structure of an atom will able (to exchanging photons with the surroundings) absorbing before dissipating certain amount of photons to the surroundings under a specific laser beam. Of course, the laser beam can't be very strong one. There is a certain spot within the electric field where the nucleus of an atom will exchange photons under the influence of the laser beam at its own optimum level where it will anchor itself at that particular spot that you called as the focal point of the laser beam. It is not the focal point of the laser beam but rather the specific spot within the electric field with specific configuration and strength of electric field. Vortexes of liquid helium-II superfluidity are due to two major factors. Firstly, the high kinetic energy of helium-II atoms (How we know this is true? Because helium-II superfluidity has very high specific heat capacity at lambda temperature). Secondly, the strong magnetic field of helium-II atoms will stagger them apart from one another while they are swirling to form vortex. Lastly, Bose-Einstein condensate doesn't in any sense prove that atoms are wavelets,. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust. .
I swear, there's at least one in ANY comment section from such videos, in ANY language, and the length of their quackery is unreal. Their only true discovery is copium condensate for their tragic insignificancy.
10:40 the lecture begins
well thank you

Great talk, I am moved by the audience's appreciation.
Hats off to you sir ...this is the best lecture in my life that i ever had
Pulsed waves of matter.
Fascinating.
maybe if I watch this enough, my advisor will turn into him
How did it go?
@@limitstates my advisor has actually gotten worse...
@@billydagenham F bro
@@billydagenham I wish you luck
This is really a motivating lecture

this is why i love physics
The guy is a rock star!
Very easy to understand. Thanks Prof. katterlee.
Extremely inspiring and motivating lecture! It certainly encourages my passion in this field! Thank you Prof. Ketterle! Thank you MIT!
56:48 defects in the lattice 🤔
Outstanding Lecture
How exciting.
Thank you sir.

who the hell dislikes a video like this! like really!
Thanks for sharing. Amazing.
Incredibly helpful....thanks a lot
Anyone sees the resemblance between the method he uses and near death experiences? Food for thoughts
Amazing talk!
伟大而动人的传承
so atoms are described by probability waves. but that's unrelated to this. these are physical waves...
many waves
We need more lecture similar to this...... Thnks sir.....
when i saw the animated periodic table i thought i was about to watch an episode of Breaking Bad.
atoms plus atoms gives vacuum!
If ever there was an argument for God, this is it. Very Godly man.

@@npgatech7 Thank you
A human being ! Put nationalism and religion out of this, Please
Why do you feel proud for someone else's achievements because they share a travel document with you? Just curious.
43:37 this is how black holes also look,got me thinking is inside of black hole a Bose Einstein Condensate
quantum soup indeed
100 mfthrs can't tell me nothin, bosons in the trap bbbosons in the trap
I don't understand even single word here, then why am I here?

Hahahaha finishing it off with “In God I trust” classic
But do you really trust your own physics? And are you sure that God does also?
