particles

Taking the moments is essentially an integration, which comes with the implicit assumption that the system you're describing has sufficiently many particles.

At least nobody will question your theories just because you don't tell what exactly your elementary particles are.

There was a liquid with iron particles in suspension into which you could dip a strip of tape.

Complexity and the number of abstraction levels do not necessarily scale with system size in elementary particles.

It doesn't really make sense than human free will should affect elementary particles, but the reverse does make (some) sense.

The experimental setup of having a human choose something is to correlate the two, not to mean that a human choosing the setup give the particles free will.

That leaves the neutrinos as the only known particles which could get mass this way.

The calculation goes like this: There are about 10^80 elementary particles in the known universe.

Lots of people died there as a result of radioactive particles that ended up in their lungs (plus the typical mining accidents).

We could also be a part of some computer simulation (with enough power you can create rules with particles and simulate the universe).

Anything airborne poses a serious hazard to aircraft, even tiny particles of ash.

Viewing magnetic recordings with magnetic particles used to be a standard maintenance tool.

"It asserts, roughly, that if indeed we humans have free will, then elementary particles already have their own small share of this valuable commodity." He goes on to show the reverse of this.
