Comment on What’s the Value of Liberal Arts? by Joseph

Sure, Will. I agree that study of and contribution to art, literature, history, and other such subjects is worthwhile for its own sake. I wanted to contend the point that a liberal arts education has little practical value but pointing out that the liberal-arts aspects of my own background have been quite valuable in my technical and professional careers – and that I see the liberal-arts college approach as therefore more valuable than a purely technical or vocational one.

It’s a complicated argument because I want to say what you’ve said above: that studying history, racism, the US after 9/11, plants, chemistry, and so on gives us a strong basis as workers, as citizens, in a way that is “objectively” useful. But that seems to cheapen the other argument – that experiencing the liberal arts is, in itself, the good – the endpoint.

That we might have a collegiate experience that embraces the earth, sky, and the vast ranges of humanity between.

Comment on The Biggest Science Errors in (hard) Sci-Fi by Joseph

I’m not sure about that. Shooting gravitons at an object might attract it towards you, but I don’t think you could generate a repulsive force.

Just wanted to make a small point that I think might recap what John said. In #2 “hard” sci fi definitely had grounding for orbit-surface-orbit shuttles. Assuming artificial gravity is actually artificial gravity and not something like magnetic plating, then the civilization has control of the Graviton, the particle that gives gravity its properties (much like the photon and light). If they can leverage that technology to make artificial gravity then it is certainly plausible that they can use it to reduce the force of gravity on a shuttle (a lot like eezo from the mass effect series).
