Astronomy, place science, look up, but mainly physics, with some chemistry and now maybe some biology!  The easiest of all sciences to start practicing; all you have to do is look up!  It is also the oldest science and the only science that started as a religious practice, astrology; and astronomers are the second oldest profession.

Computers, you can't do anything today without using one, in some sense you are one, too (a massively parallel machine with very simple processors, neurons, and probably 100,000 GigaBytes of storage, memory).   The earliest artificial computer did astronomy and was called an astrolabe; Java (enabled Browser astrolabe)  WinTEL (Electric astrolabe).  {Of course the universe may be a computer in the mind of God, what ever that may mean!  I do not mean this in a new age way, what ever that is.  Words are tricky things.}

• Some other Newspapers
• Florida Times Union, I grew up in Jacksonville, Florida, this used to be a really poor 'southern' newspaper, but it lets me keep up with who was murdered locally (they still cover local news sort of).  My high school physics teachers, Roy Dickens, was killed by a student, not one of his, a couple of years ago.  He was an unbelievably good teacher.  I keep hoping that the newspaper will undergo a renaissance; guess what this newspaper has undergone a renaissance.  I traveled to Jacksonville (May 29 through June 6, 2009) to visit my parents and in-laws and have read this paper.  It is really good now.  The Times Union is now the best newspaper that any newpaper of a city this size can be.  If I lived in Jacksonville, I would subscribe now. It is worth reading.  Yeah,  Jacksonville!
