Science: Levitation is real (video)

Scientist explains how to levitate objects with sound

(WIRED) Believe it or not, levitating objects aren't just the stuff of yogic powers (siddhis), science fiction, or stage magic shows. There are actually many different forms of objective, demonstrable, replicable levitation, including something called acoustic levitation, which uses powerful sound waves to trap objects in mid-air.

WIRED spoke with a physicist at Argonne National Laboratory to find out how acoustic levitation works and what it's used for.

Acoustic standing waves and the levitation of small objects

(Harvard Natural Sciences Lecture Demonstrations) Oscillations and waves acoustic levitation meets schlieren imaging:

By reflecting a sound wave back onto itself, one can secure a standing wave if the distance between the source of the sound and the reflector is equal to an integral number of half wavelengths.

Summary of Real Magic (Dean Radin)

In this demonstration we use 28 kHz ultrasound whose wavelength in air is 1.2 cm. The objects are small Styrofoam spheres, roughly 4 mm in diameter and 1 mg of mass. Images employing schlieren optics are very sensitive to changes in the density of air, and these changes refract light into the camera.

Note that the little spheres settle down where there are bright bands of light. The bright bands of light in the schlieren images are known to be the result of either increasing or decreasing air pressure with respect to vertical position — in other words, the pressure nodes.

Science can already levitate small animals.

For an excellent writeup by David P. Jackson and Ming-Hua Chang on the mechanics of acoustic levitation, see American Journal of Physics 89, 383 (2021).

For more information on our schlieren optics set-up, see sciencedemonstrations.fas.harvard... Although 28 kHz is beyond the range of human hearing, ear protection should be worn whenever attempting this experiment to avoid damaging vibrations in some parts of the ear.

The sound you hear in this video is not ultrasound but rather a subharmonic and is not dangerous to the ears.

Curing cancer with (banned) Rife technology

Healing with light and sound is the medicine of the future (energymedc.com).

The Reasonable Persons Guide to Strange Ideas next examines one of the most astounding claims on the Net.

Overview of Claims

Some claim that Dr. Royal Raymond Rife (1) developed a super microscope, (2) was able to see live viruses, (3) which gave off their own unique light [frequencies], by which he found that (4) all the forms of human cancer he studied were caused by the same viral infection (BX virus), and that (5) these cancer viruses will shatter both on microscope slides and in living animals when exposed to certain frequencies. (6) His 1934 Rife Ray Equipment at the University of Southern California cured 14 helpless cancer cases after three months and eventually 100% of the 16 cures attempted. (7) Rife worked with top people in medicine at his time including doctors at the Mayo Clinic. (8) Rife won scientific awards. (9) Drug companies and electron microscope competition suppressed him and all others who succeeded in duplicating his work.

Was Rife a scam artist? Or did he cure cancer?

The Rife Microscopes
No one doubts that Royal Raymond Rife was a real individual who did indeed create several unique microscopes. Some very fine pictures of his scopes exist today. The one below is the Universal Microscope, one of five scopes purported to have been capable of seeing living viruses.

One microscope expert reading this article wrote that Baush and Lomb offered Rife "a ton of money" in the late 1930s. But B&L ran because the microscope was a fraud. So far my request for documentation of this claim has gone unanswered as has the question: If no Rife scope worked, how does one explain the nice photos of Tetanus spores and Typhoid Bacillus taken by Rife's Universal Microscope published in the 1944 Smithsonian Report?

Goal of This Article
This author hopes to entice readers to think, to learn, and to explore science. This article (still a work in progress) will walk through various Rife claims from the perspective of an open minded independent scientist. The aim is to make this intelligible to anyone with a basic high school or college education. To understand the claims, a few terms must first be defined. More

Zen of Blind Art (Seeing Sound)

New scientific discovery: Humans can see sound (story below).

The book Zen and the Art of Motorcycle Maintenance (overview) by Robert Pirsig holds out as one of its central premises that it is possible to flow effortlessly, to become natural and childlike (Zen mind/Beginner's mind) in every action. Zen, in terms of the art of archery, speaks of the possibility of developing enough skill to hit a bulls-eye in the dark.

Is it literally possible to "flow" and "feel" one's way in the dark -- or is it only a metaphor? The following artist (blind from birth) is turning brain science on its head, suggesting that Zen was being literally all along. And a new neuroscience study seems to confirm it.

Turkey's Esref Armagan is a blind painter who does the impossible.

Scientists Say We Can See Sound

Your brain's visual system can be employed to hear, according to a study of monkeys. Scientists figure this might be one reason blind people develop keen hearing. (Image credit: Dreamstime)

Turning conventional neuroscience on its head, new research suggests the human visual system processes sound and helps us see.

Here are the basics of what was Neuroscience 101: The auditory system records sound, while the visual system focuses on visuals, and never do they meet. Instead, a "higher cognitive" producer, like the brain's superior colliculus, uses these separate inputs to create our cinematic experiences.

The textbook rewrite: The brain can, if it must, directly use sound to see and light to hear. The study was published last week in the journal BMC Neuroscience. More >>

Extra-sensory power?
The discovery is likely un-related to the rare experience of synesthesia, a bizarre condition experienced by a few people who can feel, hear and taste colors. In synesthesia, for example, more complicated sensations combine at later stages of brain processing, so that just the mention of a color, a letter, or a shape can automatically trigger the perception of a certain note.
