I wouldn't be worth my salt if I weren't attracting some controversy and criticism. Everyone in the world who has done something in life has attracted criticism.
There is a difference between responsible criticism that aims for success and defeatism that refuses to acknowledge anything but failure. Hindsight alone is not wisdom, and second-guessing is not a strategy.
The sceptic will say, 'It may well be true that this system of equations is reasonable from a logical standpoint, but this does not prove that it corresponds to nature.' You are right, dear sceptic. Experience alone can decide on truth.
I lose my patience, and I own it too,
When works are censur'd, not as bad but new;
While if our Elders break all reason's laws,
These fools demand not pardon but Applause.
