This is a practice exam question on a course relating to the history of science that I am trying out in order to prepare for my exam, but I am kind of stuck on this question. I hope somebody can help me out! http://www.geocities.com/asdfasdf23135/HPS1.JPG [Total marks: 7x2=14] I would match: Leibniz with calculus (or Newton? I am not too sure whether each person can be matched to multiple answers...but the total marks for this entire question is 7x2=14 so maybe not...but how can I pick only one of them?) Newton with reflecting telescope Leeuwenhoek with protozoa Halley with comet Galileo? I have no idea which should be match to him... Hooke? Descartes? Can anyone please help me out so that I can gain more confidence before writing the exam? Thanks a lot!
