A small example...if I purchase one unit of a product that's a small part of a bigger piece of merchandise, but still sellable..the human cashiers usually overcharge me...but if I use an electronic self check-out, the computer always gives me the correct price.
In another realm of AI, Raymond Kurzweil predicts that a pc will by the year 2020 match the computing speed and capacity of the human brain.

There are two weights, each of which are 37.73N and 90.944N. They are arranged like so:

http://i91.photobucket.com/albums/k285/happygolucky2442/aaaaphs.jpg

By using triangle trig, it is possible to find the tension in the three ropes (lines touching the weights). Can anyone help me find the answers (the three tensions in newtons)?

Can an Management Information Systems degree net as much as an engineering degree? I have a 2 year degree in computer science as well as 2 year degree in drafting. I have 5 years of drafting experience, but just started a job recently working more in the MIS realm. I want my 4 year degree. It would be much easier for me to finish an MIS degree. I need something like 60 credit hours as opposed to 100 credit hours for an engineering degree....as I took many of the wrong classes initially.
