    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.

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.

    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.
