but checking the pressure of a tire is a MEASUREMENT not an observation, LOOKING a tire and seeing it is soft is an observation... that is why i ask if he is using the words interchangeably when they really are not interchangeable
one is active the other is passive like active vs passive SONAR
or am i missing something?
thx for putting up with me here
Well, to be honest, I'm actually a little annoyed with you. You promised that you would be asking stooooopid questions, yet all you've been doing is asking great ones! And if you don't cut it out...
Now, this is an interesting parallel to the question... When you take the pressure of a tire, air escapes, so the pressure you get is different from the pressure that was in it before you measured it.
