We know that Rossi makes these (elementary to a specialist) mistakes.
They are not just elementary to specialists. They are elementary with anyone with a high school diploma.
When he was calculating Kelvin vs, Centigrade values and his Centigrade values where higher than his Kelvin values, this was pure incompetence that anyone can see.
He only corrected them after I contacted him correcting his math (it was quite hard, minus vs plus).
I can prove this to anyone who asks.
The fact that someone like this could supposedly write a high-level physics paper "with the highest number of full reads" it total idiocy.
