I am not that legendary that you really wanna discern about me. But as Facebook has prepared this column so I deduce I have to. Well, I am just like LIGHT. Just like light which acts as both particles (as proposed by Newton in Corpuscular Theory) and waves (as proposed by Heisenberg in Wave Theory after Youngs Double-Slit Experiment), I too am somewhat like it. Means you cant portray me (neither too I can myself). I am sometimes Potassium or Radon or Hydrogen or Lithium or Fluorine or Carbon or Oxygen or Cesium. I can be anything, it only depends upon the situation..just like Lithium (have many exceptions). So its a little tough you know, just like the formulation of Law
