Radionics is essentially like "voodoo dolls". If that doesn't tell you enough, check out the wikipedia article.

HOW DO I RADIONICS?
TGRR,
Has his targets all picked out, but has offended the Voodoo Gods.

Thats my point. You take something that signifies a person and you use it as a focus for "healing". Its voodun.

It doesn't.

Electromagnetic radiation (e.g., light) has momentum. When it strikes a surface and is reflected, its momentum changes, and because momentum is conserved, the thing it bounces off of gains momentum equal and opposite to the change in momentum of the photon.

This concept sort of reminds me of the Star Trek episode
Catspaw. Compare:
Radionics:QuoteRadionics is the use of blood, hair, a signature, or other substances unique to the person as a focus to supposedly heal a patient from afar
Star Trek:QuoteIn the mythology of your race this is called sympathetic magic. Jackson, the crew member who returned to the ship. You wondered what killed him. I made an image of him. In the essence of my thoughts the image was Jackson. And when I killed the image and knew that it was dead, he died
-------------------------------------------------------------
Radionics:QuoteModern practitioners now conceptualize these devices merely as a focusing aid to the practitioner's proclaimed dowsing abilities, and claim that there is no longer any need for the device to have any demonstrable function. Indeed, Abrams' black boxes had no purpose of their own, being merely obfuscated collections of wires and electronic parts
Star Trek:QuoteKIRK: I wasn't sure before, but I am now. This is the source of your power, isn't it. The transmuter.
SYLVIA: No, not the source. It's merely an amplifier. The mind is the source. Mine is simple, but yours has the key but you don't know how to use it.

^^^ That's really the only sentence you needed.
All sympathetic magic is sympathetic magic.
Why might a particular model or technique of sympathetic magic work?

Actually, if you read the wikipedia article, you will find that the initial assumption of radiation pressure powering the vanes was proven incorrect. It is in fact some sort of tricky thermic turbulence of the residual air molecules thing going on that pushes the vanes around, as can be deduced from the fact that the device only works in a "weak" vacuum. As soon as they figured out how to make "harder" vacuums, with better pumps, the device stops working because there aren't enough molecules left in the bulb to push the vanes around.

Exactly, Its not an absolute vacuum but its pretty close. There is a temperature difference and a pressure difference on each side of each fin, (not quite 'Lift' but kinda similar).
It moves because it is low mass and there is low friction between the blades and the axle, increase the mass or the friction and it stops working.
