hela
i remember doing a report on henrietta lacks and her remarkable cancer when i was a freshman in high school. this was long before the internet. one had to find the printed copies of the annual indexes of all of the major science magazines for the past five years. then one had to search each page with one's own eyeballs for HeLa. this could take all day. but now you had a list of magazine articles to read. then you had to find the actual physical hard copy of the magazine. which was a pot shot. cause often other report writers had some of them. which makes google a frikken miracle. cause the time it takes to do all that work now is measured in milliseconds. which is a mixed blessing for students. cause my kids write a lot more reports than i ever did. cause the research part is trivial. and typing a report into a computer is a whole lot faster than writing it by had. well, writing legibly anyway.
