We know what's going on there, there is no mystery. We did not know what was going on here.
Why does the fact that people spent time figuring this out bother you so much?
- JoeAltmaier 12y agoDoesn't bother me 'so much'; just enough to spend 30 seconds typing the question. Other than scale the 'science' involved was small. My Aunt left an axe resting in the crotch of a tree 30 years ago; last year the wind broke the tree in half where the axe had grown into the trunk. Anybody going to run out there and calculate all the forces involved, the tensile strength of that tree, the minimum wind required to accomplish the break? Is this 'science' any different than rocks on a flat surface?
- scott_s 12y agoYes, it is different. We can confidently explain the mechanisms that lead to the tree falling down. We could not confidently explain the mechanisms moving the rocks.
- JoeAltmaier 12y agoUm, horizontal force, low friction? What's left to explain was exactly how that force got applied, and under what conditions the friction got low. So the answer wasn't really physics at all - it was some empirical study I guess.
