Change, Crisis, Catastrophe…
Topics: Civilization, Climate Change, Democracy, Existentialism, Global Warming In my post on Friday, two weeks ago, I compared the Earth to a plastic or glass bottle in a microwave. Of course, YouTube has an example of someone not taking Thermodynamics seriously. After a LONG two minutes and some change, the explosion is a sad butContinue reading “Change, Crisis, Catastrophe…”

Beyond Attogram Imaging…
When X-rays (blue color) illuminate an iron atom (red ball at the center of the molecule), core-level electrons are excited. X-ray excited electrons are then tunneled to the detector tip (gray) via overlapping atomic/molecular orbitals, which provide elemental and chemical information about the iron atom.
