Silicone oil droplets provide a physical realization of pilot wave theories

The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, “I think I can safely say that no one understands quantum mechanics.” This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can’t give us an actual account of where the particle went or where it will be at some later time.

Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren’t observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion.

In this video, physics educator Derek Muller uses silicone oil droplets to depict what the quantum world may look like, at least according to one interpretation of quantum mechanics.

Want to build a magnetic levitator in under two hours? With a total of 7 parts, including the coil, it just cannot get simpler than what [How-ToDo] shows here! It is not only an extremely simple circuit, it also has the advantage of using only discrete…

Does any one know how I can get the sound from HDMI from the raspberry pi 3?

cool idea
Michael Graham, 27, an engineer from Portland, Oregon, has designed an ultrasonic 3D print polisher, sharing the building process on Instructables. The Automated Ultrasonic Misting 3D Print Polisher PRO uses acetone vapor to apply a professional polish to ABS 3D printed parts.

[David Ferguson] has put together a nice little tool called Pi Bakery. Half MIT Scratch, half configuration utility, it puts a nice visual face on all the various start-up scripts, and kludges that the Raspberry Pi community uses to configure the popular…
