The word “frequency” ranks right up there with “quantum” and “energy” as a pseudoscientific buzzword. It is increasingly prevalent in product advertisements and in CAM claims about human biofields and energy medicine. It doesn’t mean what they think it means.
I have written about Power Balance products, the wristbands and cards that allegedly improve sports performance through frequencies embedded in a hologram. They amount to nothing but a new version of the old rabbit’s foot carried for superstition and their sales demonstrations fool people with simple musculoskeletal tricks. I addressed their ridiculous claims (including “We are a frequency”). I pointed out that
The definition of frequency is “the number of repetitions of a periodic process in a unit of time.” A frequency can’t exist in isolation. There has to be a periodic process, like a sound wave, a radio wave, a clock pendulum, or a train passing by at the rate of x boxcars per minute. The phrase “33⅓ per minute” is meaningless: you can’t have an rpm without an r. A periodic process can have a frequency, but an armadillo and a tomato can’t. Neither a periodic process nor a person can “be” a frequency.
