Science & Mathematics - 6 October 2007

As science and technology leads us to new products, the electronic and software at an incredible rate, it would seem that the damage caused by fallen industries (because some product just was not the best at that time).....would create alot more turmoil, and loss of jobs/stock market investment. Can anyone give an example of how these R & D in all these companies complement each other, or create new directions instead of destroying them by competition?

Seeing the world we are living in today is so widely saturated with wireless or cellular toys. Be it the phone, computer, radio,
television, and the list goes on. I have been wondering if one of these days the well-known insulated 'sparks' will become airborne also, not to mention being safe in the first place. On second thought, maybe some geniuses have already engineered the solution...

We've all (or majority) of us got two hands and two feet, why does one have to be better than the other at doing stuff???
And how are some people ambidextrous, do they practice using both sides for things like writing???

I am a senior in college and will graduate with a degree in Economics. I have come to realize that engineering is my true calling and would like to pursue a career in that field. I was wondering if instead of going back and starting undergraduate in engineering, is it possible for me to get a masters in engineering even though I did not graduate in engineering? would i just have to fulfill some pre-req such as calc 1-4, physics 1-4? or is this entirely not possible?
