Bohm, I truly do hope the PM you sent me, the one where you said I was rude, nasty, silly, defective, a troll, having inflated self-confidence, not suited to teach and ignorant of anything other than the barest of high school math, I really hope that made you feel better.
It really must sting you to have been taught about gravitation and shell theorem by one you regard in such low esteem. The pain will subside, I promise. I once held you in high regard for your knowledge and I thank you, from the bottom of my heart, for reminding me that education often does nothing to improve a person. You could not have written me a better message to show me what kind of person you are.
I truly and sincerely hope you have a great day, week, month and rest of year and happy holidays.
