[QUOTE="johnlittletree, post: 1508768, member: 105653"] Not only is that a problem but what counts as a standard day at Sea Level is not at all universal each field has it's own version of a "standard day" in Aviation : Standard day [B]parameters[/B]. For Pilots: At sea level, Altimeter:29.92 in/Hg at 15 °C (59 °F) The "standard day" model of the atmosphere is defined at sea level, with certain present conditions such as temperature and pressure. Even in music various countries use different tuning for A in the USA A=440 is the modern norm but that is not at all universal. Likewise we normally think of the speed of light as a constant but if you dig deep enough you soon find out that the speed of light has had many different speed's attributed to it. Anytime anyone thinks anything is simple and universal I laugh because that is either a sign of ignorance or stupidity since almost nothing is universally agreed upon the deeper you dig. For the most part a large chunk of the worlds problems stem from people wanting nice neat well defined problems, causes and answer's that can have a neat little package with a ribbon and nice labels. Most people do not want the truth and do not want to be educated. They want simple and absolutes. [/QUOTE]
