Very nice blog w/ a wonderful idea. My question is: can I create an ultrasonographic machine with just a probe and laptop?

Yes, and you wouldn't be the first. The question is, do you have the probe and do you have software for it? There are apparently many laptop-based systems.

Here's one.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
