from memory the only ones who are known as the father of calculus are leibniz and newton so if you are going to delete any more names unless it is an obvious one please relocate them to the talk page so we discuss person by person i'm trying to work on this page as a whole and i really only want to chip away at it a little per week seeing that there are ambiguous issues with founder in the title getting confused with father maybe we will have to move the page to people known as the father or mother of something but then again in modern terms many authors are using the term founder as it is more politically correct and gender neutral as for your deletions i would rather like you to replace those names with who you think is the father of those subjects and why thank you for your cooperation references issue david and carl have jumped into this article and have somewhat demanded that every name that only has a website reference needs to be deleted myself i am new to this page as to major edits aside from reading it previously and over the last five years i understand that the standing rule at this page was that a new entry needed to have at least one reference hence if david and carl are proposing new reference requirements e g two or more only book references etc then i want to hear their proposals below rather than just using edit comment boxes with random comments in this manner we can try to clean up correct add better references etc to what we have now and then any future additions can follow stricter rules that we all agree on thank you
