I am only an engineer but I have worked in science labs for 30 years. I wait till an experiment is finished before I draw conclusions.
I just did such an experiment today on a high vacuum system.
I had done the same test on the same equipment a week ago and did the same thing today.
Venting the system, cleaning it out with minimal IPA, closing it up, roughing down the vacuum to 40 microns, here is my experiment:
Rough to 40 microns, turn off roughing pump, time how long it takes to add 10 microns, ending at 50.
So the first time I tried that, it took about 4 minutes.
By the 5th try, it was taking over 40 minutes.
My conclusion was outgassing from the walls of the inside of the chamber was causing early times. Later, outgassing almost ceased and it took ten times longer.
So today I did the same experiment.
Except this time I had to do a much more thorough job, used a lot of IPA to clean inside surfaces.
Same thing, rough to 40, turn off roughing pump, time to 50.
This time it started off at 2:35 seconds.
And took 8 times to get to 4 times, double double of time.
I was a bit surprised by the longer times it took to double and such.
I had also recorded a few other parameters like the room temperature and humidity and time to pump back from 50 to 40.
I had to do the entire experiment 8 times so I could now reasonably conclude the added IPA (alcohol) was really adding to the outgassing internally so it took longer to get even close to the first experiment.
I also took down the times it took to pump from 50 back to 40 and saw a much smaller decrease each time, presumably it would reach an asymptote of time where no matter how many times I would repeat, the time to pump from 50 back to 40 would be about the same.
I saw that asymptote approach and reasoned that the first few times I pumped I was pumping out higher AMU molecules, IE, alcohol, IPA, and later only water vapor, N2, O2 and such, much lower AMU molecules.
So I went into these experiments with no faith at all. Had no idea what I would see.
As I built up data, I now know more than I did before about the vacuum system of that one machine and I will see if it applies to others of the same type.
There was no faith there, I didn't have a clue what the results would be and I didn't expect to find such a difference the second time round.
That is the nature of experimentation and science.
You don't project, have some kind of faith an experiment will turn out the way you think.
You leave your ego out of the equation completely and just record data and then figure out what happens later.
The problem with YOUR faith is your ego never leaves your head, you always project, have faith, that the age of the Earth is 6000 years old and no amount of further scientific examination of that hypothesis that would refute that would have any influence on the rational part of your mind at all.
Your dogma would stay the same. THAT is faith.
You know exactly what cognitive dissonance is.
You have it BIG TIME. You cannot process experiments and procedures that have fully refuted the Young Earth fairy tale a thousand times over.
All you can do is fall back on your own ego, your faith tells you no matter WHAT scientists come up with, they are wrong.
