Does anyone know what are currently the science fields in highest demand? I have a friend that was a chemist but couldn't get into a company with much job security so she switched to radiation and easily found a good job. I was thinking of maybe going into a science field myself, but rather than jump into something I wanted to get a good feel of what would be the demand for the training I would choose. I really have an expansive set of interests so there doesn't seem to be any aspect of science, math, or any subject that I am not very interested in learning.
