<p>I completely undertand your point bigtrees. I want to get involved in something that could be revolutionary. I like the idea of going into something that has a few more unknowns. I know nuclear energy is not being pursued as of yet, but I think it will be in the future. I like the idea of getting a major with a specific purpose, whereas mechanical leaves you with broad knowledge which is good dont get me wrong, but I would have to do more work to settle into the niche that I am interested in. Norris made a good point in saying how the first two years are nearly identical for nuclear, mechanical, and to some extent most other engineering fields. If I wish to take the approach you have mentioned, it should not be hard to switch at all.</p>
