I'm taking an intro to geology course on minerals/gems and there seems to be like everything in South Africa: PGE's, diamonds etc. What is it about RSA's location(?) that makes it so mineral rich?
So we were doing a chemistry lab and the question comes up, how would astronauts pipette in space? Is there like a zero-g micropipette or Pasteur pipette? If not then how would you perform precise experiments in space?
