    When all of this is going on around us on our little ol' Earth, I am amazed anew.

    Should connect a flare to a line gun so once the flare is shot it will bring a string of flares attached for rescue purpose. The line should not break easily to trace to the shooter, and should be able to stay alight for 2 hours once the line drops on the ground.

    Optical Emission Spectroscopy or OES is amazing stuff.

      It is till used extensively today, but what really wows me about it is how much some of the earliest chemists were able to deduce about the structure of atoms from just a few colored lines.

      @@ChemSurvival the founders of the company had a huge reference set of film plates to work with. And It was published by the Vatican press which made me smile. We have come a long way and then out into space

    This is a random question, but I'm curious why it shows the third electron for Lithium in the 2p subshell instead of the 2s?
