15. 3 0405 x1845 Thanks for your interest and we look forward to hearing from you Editors Note We just had a leap day This got me to thinking When and why did we start having a leap year With help from the Internet I learned that Julius Caesar introduced the first Leap Year during the time of the Roman Empire over 2 000 years ago The reason given is because it takes the earth 365 242199 days to revolve around the sun According to scientists if a Leap day is not added about every four years then in 100 years the calendar would be off by approximately 24 days There s also certain criteria which must be met in order for a leap day to be added to the calendar the year must be evenly divisible by four AND it must also be equally divisible by 400 otherwise it s not a leap year And all this time I thought it was for AutomationDirect to have more time to provide quality products for our customers This issue of NOTEBOOK is filled with interesting articles and bits of information that just might inspire you to try something differently In addition to information regarding our newest products this issue is packed with great articles such as the User Solution story which features an Alaskan fish hatchery Plus students at Boise State University are featured in our Student Spotlight segment trying to break a land speed record with their vegetable oil powered 1998 Chevy S 10 pickup truck There s a
