The “disease–frequency” lists circulating online largely trace back to the 1930s and the American inventor Royal Raymond Rife. Rife claimed to observe living microorganisms through an optical microscope of his own design, and proposed that every organism has a characteristic vibration rate — in his phrase, a “mortal oscillatory rate”. At the right frequency, he argued, the organism would shatter like a glass struck at its resonant note.

Why the story is appealing

It is not hard to see why this narrative has lasted. It contains a simple, visual, memorable metaphor: the glass broken by resonance. And it comes with the story of an excluded genius — the suppressed invention, the ignored inventor. Put those two together and you get a narrative that reproduces itself whether or not it is ever verified.

Scientific status

Rife’s claims have never been independently verified and are not accepted by established science, then or now. There is no reliable evidence that the devices attributed to him worked. This deserves to be said plainly.

The shattering-glass metaphor is itself misleading in physics terms. Breaking a glass requires both a very narrow resonant frequency and an extremely high sound pressure; it is possible because a glass is a rigid, dry, lightly damped object. A bacterial cell, by contrast, is an exceedingly small and heavily damped structure suspended in fluid — it does not present a sharp resonance peak of its own. As scale drops, viscous friction dominates and the resonance phenomenon effectively disappears.

How the lists became what they are

Over decades these lists were copied from forum to forum and file to file. With each transfer new values were added, existing ones altered, sometimes corrupted by a simple typo. Attribution generally vanished; in most cases it is now impossible to trace where a value came from.

That is why different sources give different values for the same condition — and why a single record in the Rezzonix catalog carries “Frequency 1, 2, 3…” subheadings. We did not hide that contradiction by picking one “correct” value and deleting the rest. There is no way to determine which is correct, and pretending otherwise would manufacture a certainty that does not exist.

So why publish them?

That is a fair question, and the answer is: people are already searching for these lists. What they find is usually scattered text files, tables of unclear origin, or device sites selling inflated promises. There are two options: leave the space as it is, or present the list organised, searchable and with its limits stated openly.

We chose the second. We position the catalog not as a claim of accuracy but as a reference list whose nature is known. That the source is contested is stated inside the app, on the catalog page of this site, and in this article — separately in each place.

What this should tell you

When using any such list, keep this in mind: a value appearing in a table does not mean the value was tested. Ubiquity is not evidence; a number copied a thousand times does not become true. Experiment if you want to — but measure the outcome, and do not assume you know what you did not measure.
