Emphasis on *routinely*.
"The difference between science and other ways of attempting to acquire knowledge is that science is iterative."
Er, have they been moving elements around on the periodic table again? Has the electromagnetic spectrum been moving around again? Have they changed the laws of chemistry again?
Or are you incorrectly equating science with metaphysics?
The periodic tables being printed today are significantly different from those I had in high school.
The electromagnetic spectrum is not the same class of concept as a periodic chart, our understanding of the spectrum has certainly been refined in the last 150 years, as have the "laws" of chemistry and gravity. There are quite a few phenomena, such as superconductivity, that were not anticipated and which are not yet fully understood.
Are you unaware of this, or are you leading up to an actual argument?
