comment Which Distribution Is This?
There is missing a very important information: On how days must a shirt been worn to be called "dirty"? If you put on a shirt at day 1 and jump into a pool of mud 5 minutes later, you are wearing a dirty shirt at day 1. But if you pay attention and don't sweat too much, the shirt can be clean even after been worn for a whole week.

comment Is there a way of intuitively grasping the magnitude of Graham's number?
So why stop at $G_{64}$? What about $G_{G_{64}}$? or $G_{G_{G_{64}}}$? And what if we increase the supscript-stack up to $G_{64}$ layers? You will get to even unbelievable bigger numbers

comment Absolute inequality derivation
I used Excel to calculate this for 225 quadruples (with x,y <= 5, all numbers integers) and found that this is always true.

comment Is $\sqrt{\log (n)}=\frac{1}{\sqrt{2}}*(\log n)$?
@VasuDevGarg: If you find just one single value for n that proofs, that both sides of an equation are unequal, then you did proof that the equation is wrong. With this technique you can't proof an equation as true if both sides match by accident. Even if you find trillions of single-value-proofs. If there is just one value that proofs the equation as wrong, then it is wrong.
