You can't have astrology without astronomy, but the conclusion astrologers draw from astronomical events are total nonsense. You can't have calculus without arithmetic, but calculus is just a device that lets you get accurate arithmetic results with less computation. Newton used it exactly that way. Leibniz https://en.wikipedia.org/wiki/Gottfried_Wilhelm_Leibniz did too, but he also spelled exactly how he was doing it which is why we use his notation, rather Newton's. -- Bill Sloman, Sydney -- This email has been checked for viruses by Norton antivirus software. www.norton.com
