The da Vinci question[edit]

I asked the original author (User_talk:Heron) to add a reference for da Vinci, which he did, and when I read the linked page I interpreted it as saying that da Vinci's involvement in observing diffraction remains questionable; so I changed it to say "by some accounts".

Free Fall??[edit]

Umm, Galileo published his results on falling objects and their distance fallen being proportional to the dquare of time well before 1640 ... why is Grimaldi getting credit for this? —The preceding unsigned comment was added by 74.223.11.2 (talk) 19:58, 28 March 2007 (UTC).[reply]

Probably it should saying confirming rather than discovering. This relationship of distance and time is apparently originally due to Domingo de Soto, sixty years before Galileo, but Grimaldi did the most accurate experimental investigations of it. See this book. Dicklyon 21:30, 28 March 2007 (UTC)[reply]
