Can two skew lines in parallel planes ever intersect?

[samoth]

if we were to talk about curved space, can the rules of normal euclidean space be bent?

Well-behaved curved geometries obey the other four axioms as far as I know, because they are either well-defined spaces (sphere, torus, etc.) or, more abstractly, because they are differential (Riemannean) manifolds with a defined metric and stuff that works with the other four postulates of Euclid. Basically, on an everywhere-connected n-dimensional differential manifold, you work in the (n-1)-dimensional tangent vector space (or bundle) of the manifold, which is a locally flat place to work (like the infintesimal distance from differential calculus).

Ah I am glad I'm not in school anymore. Though I do miss the higher thinking part. Now I just design medical devices.

I'm specifically interested in the 5th postulate of Euclid and how it contrasts with non-Euclidean geometry

That's an area I should look into besides pharm dev.

How limited is it to just engineers?

5th postulate failing = non-Euclidean.

Degree to which fails = curvature tensor

Curvature tensor = allows metric and one to define curvature

Just engineers do the designing. We have people with science degrees design experiments, validate, verify, test and do all sorts of things with the instruments. I think you're overqualified for that outfit.

It's been my experience that groups of scientists together in the professional world harbor a lot of resentment towards others and especially engineers (engineers get paid more at my work). They like to hoard ideas and are kind of secretive about things. This is especially true in the chemistry field - something about them makes it a nasty work environment. My ex will agree 100% - she worked for a defense contractor and endured it throughout school. Often times the scientist is not concerned with making it work and short deadlines, but more interested in just testing and finding new things out - which is also important to product development, but not as much to a competitive marketplace.

We have a Physics Major with a Master's Degree. He's a great guy. I think he was definitely over qualified for the position. He's going back to school for a master's in systems engineering, something our company recently has felt the need for.

That being said, I dont think a physics degree necessarily black balls you from the field. If you have enough experience with design programs (solidworks, Pro/E, Catia) then that would easily supplement a lot of the schooling. With a Master's Degree then management positions come a lot faster than with a Bachelor's (if that was your goal), and a technical manager is a highly regarded position at our work. No d-bag with an MBA or general business degree would understand the dynamics well.

Awesome post.

The med devices area of biotech is the one that's pretty unfamiliar to me. I've been looking into it more and debating if I should add it to my potential list of job interests. I really need to do more research, though.

That seems a rather extreme way of normalizing a wave function, but okay, sure.
