> Possibly, though if we want to be pedantic "weighting" has shifted from merely meaning "increased in weight" to meaning "biased through manipulation"

Not sure what your point is here. Yes, that is the meaning that is being discussed. You understood it yourself. Grandparent understood it as well. What value do you feel bringing up this point brings to the debate?

> like a weak magnetic field acting on a magnetized coin

Probably not. The field will act through the other face of the coin as well. The coin is pulled towards the magnetic surface, but it doesn't alter the revolution of the coin. If the field is sufficiently weak to not pass through the coin then it wouldn't have any impact on the other side either.

The exception would possibly be mu metal or something else that prevents the magentic field from acting on one face entirely, in combination with a strong magnetic field, and I'm still going to lean towards "probably wouldn't work". It would still intermittently pull the entire coin towards the surface, it's not clear that it would counter the rotation of the coin itself.

> even a one surfaced approach is possible if you make use of carvings on the surface of the coin to get a favorable result from air resistence

No, because air resistance is acting on both sides of the coin at once. The air resistance is a constant A+B, not A,B,A,B.

> lastly you can even achieve it through density

No, this is the entire point of the article. The coin doesn't revolve around its geometric center, it revolves around its center of gravity. By changing the density of one side (balsa wood and lead, as I said) you change the center of gravity but the coin itself has the same rate of revolution.

Considering you were the grandparent, I guess that should be somewhat reassuring.

FWIW, I interpreted your use as rigid in the same manner as the GP (of this post).

As far as I’m concerned a electronic bistable generator that is biased through manipulation is effectively a “weighted coin”.. those exist.. and are counter to your claim unless you restrict “weighted coin” to the completely literal.

God no, GP here means the contextual grandparent of the topic, as it always does. GP means the person I responded to. Why in the world would I respond to myself just because "GP"?

If you haven't read the rules, you need to be giving the most gracious reading of the comment chain here. Pretty obvious what the implication was. Try reading again.

> As far as I’m concerned a electronic bistable generator that is biased through manipulation is effectively a “weighted coin”

Oh cool you're trying to impose a change of topic from the ability to literally bias a coin when a normal person flips it randomly, into telling me to defeat... all attempts of people manipulating all RNGs ever?

Super weird angle for a discussion about flipping coins. Not really interesting.
