implicate order
To describe wholeness, David Bohm used an ink-in-fluid analogy.
The situation comprises of two concentric cylinders in between which there would be a highly viscous fluid on which surface a droplet of insoluble ink would be placed.
As the outer cylinder is rotated, the ink transforms into a thread-like ellipse following the motion of the fluid. The situation is now whole, which is to say that the particles forming the thread are present everywhere at once, and any slice of the fluid now contains the whole situation. Bohm calls this the implicate order.
The explicate order unfolds out of the whole when all particles are united again and are visibly explicate.
ferrofluid
Ferrofluid is an oil-based fluid that contains magnetic particles and responds to magnets by changing shapes according to the intensity of the magnetic field.
binaural beats
Binaural beats employ sound to stimulate and entrain brainwaves to change a person's mental state by sending separate signal sine waves to each ear.
When added together inside of the brain, those signals create a modulating sound. The brain, then, entrains or adjusts to the speed of the beating which is equal to the difference in pitch between both tones.
