For instance, how do the radio astronomers in Contact (the Jodie Foster movie based on Carl Sagan’s novel of the same name) infer the presence of extraterrestrial intelligence in the beeps and pauses they monitor from space? The researchers run signals through computers that are programmed to recognize many preset patterns. Signals that do not match any of the patterns pass through the “sieve” and are classified as random. After years of receiving apparently meaningless “random” signals, the researchers discover a pattern of beats and pauses that corresponds to the sequence of all the prime numbers between 2 and 101. (Prime numbers, of course, are those that are divisible only by themselves and by one.) When a sequence begins with 2 beats, then a pause, 3 beats, then a pause… and continues all the way to 101 beats, the researchers must infer the presence of an extraterrestrial intelligence.
After two years, I applied to Saint Joseph’s University. I had all intentions of becoming a undergraduate student that lived on campus and got involved in every way possible. When I was not approved for private loans without a cosigner, that dream quickly fizzled out. I made the decision to drive the 15-miles to campus each day. While I wanted to quit my job and put everything I had into my education, that just wouldn’t be a possibility. I could not and would not in good conscious leave my mom with a $ tuition bill each month. I continued to work 20-30 hours each week to help lessen my mother’s financial burden.
Australian ABC radio reported on September 24, 2008, that Armstrong would compete in the UCI Tour Down Under through Adelaide and surrounding areas in January 2009. UCI rules say a cyclist has to be in an anti-doping program for six months before an event, but UCI allowed Armstrong to compete.  He had to retire from the 2009 Vuelta a Castilla y León during the first stage after crashing in a rider pileup in Baltanás , Spain, and breaking his collarbone .  Armstrong flew back to Austin, Texas , for corrective surgery, which was successful, and was back training on a bicycle within four days of his operation.
