See that just what I mean The universe is counter-intuitive The farther away Earth gets from the sun On its elliptical course, of course (Otherwise we wouldn’t be having this discussion) the hotter it gets This depends on which hemisphere your in as noted above which brings up the rotation of Foucault’s Pendulum but I have another interesting snippet of unbelievable ness The Pyroxene group is one of favorite rock forming minerals I’m sure we can all agree to that As we all know pyroxene are made up of chains of silicon & oxygen atoms, spaced a nanometer (10 -9 meter OR 10 -7 centimeters) apart. Obvious! What is not so obvious is this: imagine unraveling a cube of pyroxene, one centimeter (0.4 inch) on a side into single chain. Would the chain reach from the Smithsonian Museum to: --The Washington Monument (one kilometer, 10 5cm) --Chicago (1000 Kilometers) --The Moon (300,000 kilometers) --Jupiter (1,000,000,000,000 kilometers -give or take a kilometer or two…mostly ) ?

I just figured out to do the subscript so this should make working out the mathematical formula easier mostly

Hey guys I know you been on the edge of your rocks waiting to check your math against the answer. You’d be right!! Even though you don’t believe your math. The correct answer is Jupiter! If the chains on the end of the crystal are 10 7 centimeters apart, then there are 10 7 chains along each edge of the one-centimeter crystal; 10 14 chains in all. Dividing by 10 5, to convert from centimeters to kilometers, gives 10 9 kilometer the distance to Jupiter. Give or take a kilometer or two. Amazing that a 1/3 of an inch cube of Pyroxene could contain that many atoms. So the next time your grinding say a, jadeite or rhodonite, think how far the shine goes! E d=M ohstly2
