This just show how shallow some of you are. Throughout the history of religion, mathematics and science, questions been asked, discussed, argued, and people persecuted and executed.
In this case, as you said "you do demonstrate a good point and you are valid in your statements". What about if I was wrong, do you think I can "feel good about yourself"? The questions were to lead to the situation where the prevalent ideas fall apart.
"feel good about yourself": This is a common phenomenon on this forum.
'Once again you always do when working with measured quantities. To know why, you need to understand the meaning and use of significant figures.' This may be condescending to certain people who think highly of themselves.
So what is good coming out of this? Some of the readers know a bit more about sig. fig. and use them correctly.
This is not about 'technicalities'. It was not technically wrong to say the natural number 17 has 2 sig. fig., it is simply wrong.
Glad to leave a place with lots of bigots. Good bye and have it your way.
