Whenever important physicists are discussed, Galileo Galilei, Isaac Newton, and
Albert Einstein seem get the most attention. However, as you've seen, Galileo
formulated or refined many of his discoveries and theories based on the findings
of others who came before him, including Aristotle and Nicolaus Copernicus.
Likewise, Newton claimed that he "stood on the shoulders of giants" in
developing his work. You've just begun your study of physics, but from what you
know (or can research and find out) take a position that Galileo, Newton, and
Einstein deserve this special recognition. Alternately, identify a physicist that you
think has been overlooked, compared to these three! DO some research and
support your opinion with credible arguments.
