Science News Daily http://www.sciencenewsdaily.org/story-6724.html Dear Folks: Wow..............1 million g's...............I had never seen van der Waals interactions measured in these terms.......and shouldn't it be considered " van der Waals forces" (london & Waals) because the electron density in a molecule is redistributed by proximity to another pole? Are individual atoms a different story? As you can see I only know enough to be dangerous or look ignorant. Cheers Erich J. Knight
