The direction of maximum slope (minimum? IDK). Arg(-grad(h))=0 where h is the height of the ground. If you're a nerd. Downhill. If...

Does the slope really matter? What if the sheep is moving perpendicular to the fall line when they get to the fence?

He's just a poor boy, nobody loves him.

5% HCl is 1.4 M, that's already quite concentrated in the context of just changing pH (yields pH in the zero range, that's seriously...

Physicists already know that GR doesn't work with Quantum Mechanics. It isn't 100% correct. Many are trying to figure this out. So, it's...

Even less would be what we did. But we were removing any left over lab detergent from the wash cycle. 5% would probably be fine.

Like 5% perhaps?

Any adhering soap molecules might be resolublize-able with a pH change. I have used weak acids for this (in lab, weak HCL, but at home...
