The risk of giving greek names to things is that later the meaning might turn out to be not so appropriate:
Atom means "indivisible"
Proton means "fundamental thing" https://t.co/W7uuldqsWD

Every prime greater than 3 is either 1 less or 1 more than a multiple of 6.
For example, 11 and 13 sit on either side of 12.
But not every neighbor of a multiple of 6 is prime: 25 is next to 24, and 25 = 5×5. https://t.co/UMJmpo9EG4

FUN FACT
During a lecture Lord Kelvin wrote an integral on the board, turned to the class and asked if they knew what a mathematician is.
"A mathematician is one to whom that is as obvious as that twice two makes four is to you. Liouville was a mathematician." https://t.co/gH5

@fermatslibrary This is a silly argument. It may look intellectual to only those who aren't acquainted with Indian philosophies. The act of presenting an argument and the opponent not changing their stance both could be as they have to be. Nothing ever needs to change.
