Never heard of him either.
What I took from the flat earth guy was he was angry there was no mathematical formula from proving the earth is a sphere. Then someone says it's just a straw man for another issue.
Live no time or patience for that kinda stuff. Solsson presented several example. I used my own cuz the moon is upside down here (Thx SB ) although I did test it out haha it wasn't as easy as I thought.
Thats not what that guy wants tho - he wants the math.
