Line 37: − − == Suggested changes== − Replace the image of Galileo with this better one. [[Image:Galileo.jpg|right|thumb|200px|Subterman's portrait, circa 1640]] − − In the paragraph: − − :Galileo’s last book, the 1638 work ''Discourses Concerning Two New Sciences'', dealt with motion and mechanics. This work helped inspire [[Isaac Newton]] to create his theory of [[gravity]], which linked Galileo’s mathematics and physics to [[Johannes Kepler|Kepler’s]] laws of planetary movement. − − change the title to "Dialogues Concerning Two New Sciences," as this is how the title is translated by Crew and de Salvio in what as far as I know is the standard translation in English. − − Following the paragraph on Galileo's last book, add: − − ---- − − [[Image:Galileobones.jpg|left|thumb|200px|Galileo's drawing of how the dimensions of different-sized bones need to vary to make them equally strong]] − In ''Two New Sciences,'' Galileo revealed a sophisticated understanding of engineering and what now would be called [[dimensional analysis]], the way in which the proportions of an engineering structure need to change as the size of the structure is scaled up. He applied this to biology, explaining why the bones of a large animal need to be thicker in proportion to their size than those of smaller animals. − − He used inclined planes as a way to study the acceleration of gravity in, as it were, slow motion. − − This book contains his famous discussion and thought experiment, in which he shows both by logic and by appeal to experiment that light and heavy objects fall at the same speed (contradicting Aristotle). One of his discussants says "But I, Simplicio, who have made the test can assure you that a cannon ball weighing one or two hundred pounds, or even more, will not reach the ground by as much as a span ahead of a musket ball weighing only half a pound, provided both are dropped from a height of 200 cubits."<ref>Crew, Henry and Alfonso de Salvio (1914), ''Dialogues Concerning Two New Sciences by Galileo Galilei,'' Northwestern University, 1939 reprint of 1914 Macmillan edition, p. 62</ref>. − − Another discussant points out that this result is logical, by positing a large stone that moves at a speed of eight and a smaller one which moves at a speed of four, and showing that this leads to a contradiction if the stones are tied together. Since the smaller stone tends to fall more slowly, it ought to retard the motion of the larger one, so the combination should fall more slowly than the large stone by itself. However, "the two stones when tied together make a stone larger than before," and hence ought to fall more quickly than the large stone by itself. − − Working without algebra or calculus, Galileo nevertheless derives his quantatitve results by applying the methods of geometry; the book follows the style and method of the books of Euclid. − ---- − − [[User:Dpbsmith|Dpbsmith]] 21:50, 3 May 2007 (EDT) − − That's a good expansion of the article providing we can sort out the other issues. I'll have a look at those over the weekend.--[[User:Britinme|Britinme]] 23:19, 3 May 2007 (EDT)
Made my suggested changes now that article is unlocked
Dont know why this page is locked, couldn't find any edit wars from the history, but never the less, here are some changes i would hope to be made to this article. Firstly, i would like to get the sentence: "but this was commuted to permanent house arrest with a generous Church pension." to be canged so that it wouldn't anymore claim the pension to be generous. There is no info that it would have been generous on the citation (40 scudies after some investigation from other sources). And in current form it now makes it look like Galileo was awarder with house arrest not punished. Allso would like to return the mention about the part of the punishment that ordered the dialogue to be burned. Dont know why it was removed on first place.
