Editor's Notes

  1. These are all good things, but what if you grow up to be an astrophysicist and try asking your grandmother for help with the current solar flair problem that's disrupting satellite signals? And what if you become a pediatric neurosurgeon only to tell the mother of the 3 year old who just died of a brain aneurism that you were just hoping her daughter's tumor would go away? Scientists have developed a way to investigate and learn about our physical world that is not perfect, but has helped us make huge advances in medicine, communications, technology and safety. Also, if your goal is not just to solve the problem, but to figure it out to prevent it from happening again, you need to be specific and isolate the solution.
  2. speculation
  3. Why let someone else do it? Because sometimes we do things, have bias, etc. that we aren't even aware of that can affect the outcome or influence our conclusions.
  4. Anyone want to differ? I had a college professor who believed this. Year after year, the young men in his classes always got higher grades than the ladies. One year, after a classmate of mine challenged her low grade in the class, it was discovered that he never even corrected our homework or tests. He would mark a score at the top and hand it back without really looking at the answers.
  5. How many of you believe that God exist? Has that ever been scientifically proven? How does that affect how you view the world?
  6. It's NOT a foolproof, completely objective process
