Two New Sciences motion and a naturally accelerated vertical motion which produces a parabolic curve. Two motions at right angles can be calculated using the sum of the squares. He shows in detail how to construct the parabolas in various situations and gives tables for altitude and range depending on the projected angle. [274] Air resistance shows itself in two ways: by affecting less dense bodies more and by offering greater resistance to faster bodies. A lead ball will fall slightly faster than an oak ball, but the difference with a stone ball is negligible. However the speed does not go on increasing
CAN-CON (convention) who came to CAN•CON and signed deals with many Canadian science fiction and fantasy writers. Of this he said, "I did more business at CAN•CON than I did at Worldcon". This informal access to large numbers of Canadian writers enabled him to spearhead TOR's Canadian publishing initiative. CAN-CON has had some of the most diverse programming SF conventions have ever had, while retaining a focus on Canada, its writing environment, and uniqueness. It has also hosted events such as book launches, Canvention with its Prix Aurora Awards, the Boréal Congress, a private label CAN-CON Wine, Virtual Reality gaming, and Co-Hosting
