No he doesn't, it's just that the two of you are talking about different things.
correct I think. She said true zero but I think meant effective zero
He's saying that once something is "out there", it's hard to get it completely removed to zero.
also agreed. I additionally said, or meant to say that there is almost always “something out there” which sounds fruity and involved with UFO theory. I just want to point out that It’s not really in this case.
Your example started off with having zero to begin with (the zero nic juice example).
These are really two different concepts. One (yours) is not-including-from-the-start, the other is removal/elimination of something that's there.
Yes and no. Starts are hard to pinpoint. The concept being described is referred to as “contamination”
An explanation of why I may have hit harder than may have been appropriate:
there is true zero and effective zero. They are not the same. I see a great deal of very damaging lying in this day and age done by confusing the two. Claiming an effective zero is a true zero and treating it as if it actually is one. If you do this enough times it is often possible with enough machination to turn an effective zero into an effective majority.
The example is juice bottles.
To do that the start needs to be examined. Suppose instead of just washing out an old bottle a new bottle is ordered from China, arrives in the bag which has been closed since it left the factory with a cap screwed on it at the factory.
The parts of bottle and bottle caps are made by molding liquified plastic pellets. The standard bottle is only one part. The cap is several. Frequently made of different kinds of plastics so different pellets made in different places. Several things made by factories in China. A lot of factory workers in China smoke. They used to and may still do it on the factory floor. So you’ve got several different places where an infinitesimal amount of nicotine may have entered the system before the bottle was even closed and put into the bag.
Is it effective zero? Yes. A useful level of zero. It might even be true zero. There is an unknown but likely small probability that there is even a single molecule of nicotine in that bottle before it is sealed. Numbers this small don’t normally matter for the purpose of living our lives. They sometimes do though. Usually it involves bacteria which are really small but replicate. Even one can become many. This is why the term “contamination” is associated with medical and hygiene stuff. If something doesn’t replicate though it’s usually a non-problem. Effective zero remains effective zero. Useful zero.
you very much for reviewing it ms. Lonna P. Gordon, great job!
