Why knocking is so important.

[pocaracas]

He, like you, was talking about net acceleration of an object, not the acceleration of gravity. He doesn't seem to have a clear understanding of what gravity does, and so lumps effects of gravitational force together with effects of other forces and treats them as an amorphous whole.

I did try to use correct wording on that detail, but I may not have made it evident enough.
And I can't remember if Drich was only talking about gravity's acceleration or some other... but, now that I write this... gravity came up as some sort of faith that Drich wishes to impose on us, right?

Well, to Drich's version of faith we have in science, I can tell you that Every year, thousands, if not millions, of university students are rehashing many of the pre-20th century experiments that yielded all the results we take for granted, today.... like Newton's gravitational constant; diffraction of light, radioactive decay, electron-positron annihilation (I know this one is from the 20th century), etc.
Heck, I did all of these.
So there you go, Drich, I don't take it on faith! I did the experiments and saw the results show up.
