871 views 4 years old and some people don’t even know we have this level of tech in undergraduate programs across the world. Ultrasonic tractor beams…

@SocraticScribe I built a basic one of these a decade ago. Cool shit and only getting cooler.

@SocraticScribe @grok explain the physics behind this so I recreate it and make a larger version into a craft I can fly.

@SocraticScribe This is essentially a phased array applied to sound instead of EM waves. The principle has been around for decades, radar, medical ultrasound, even Starlink’s antennas use it. What’s new is the miniaturization and the ability to run the fast computations needed to make it

@SocraticScribe Your mum is so fat she needs an ultrasonic tractor beam to get out of bed in the morning

@SocraticScribe 4 years old. So the project is finished, where are that with this now?

@SocraticScribe You should avoid citing the number of views. Some may find it insulting. Nobody controls YouTube algorithms.

@SocraticScribe I had previously wondered whether it would be possible to use sound/vibration in this way to create complex shapes for casting. The vibrational fields become the moulds, in other words. Maybe in a few years time it will be possible for us.

@SocraticScribe Wow it's almost like all of it is vibration, and frequency. Who knew. 🤷‍♂️

@SocraticScribe ...du lévitron au neuon...

@SocraticScribe the future is so bright it makes me cry. All the best music has yet to be made ... words can't describe it

@SocraticScribe @grok how do I go about building one of these devices in the video? At one point the kid is holding a white hand held model which i would like to replicate. I need instructions on how to create any of these devices. Also I want you to explain how it works
