		<description>[...] Sure, earmarks are dumb, and it would be nice to have a rational way to decide how best to prioritize federal spending. But don&#8217;t deny the obvious: when Republicans hear &#8220;science,&#8221; they think &#8220;something to be mocked in the service of burnishing our just-folks credentials.&#8221; Ask Bobby Jindal.

		<description>When I visited the South Downs Planetarium, hosted by Dr John Mason (BBC The Sky at Night), in West Sussex, early this year, I was asking him just as much about the projector, as the effect it creaTED on the under side of the dome, because it was a work of incredible machinery in its own right. I was in awe of the projector and how he got together its working parts.

There is a circular (logic...) brick wall araound the projector, as well, as far as the McCain's comments go...

..if they stop money for a planetarium, the next generation of kids becoming inspired by astronomy and science could become extinct by its closing. If so, at some point, that very kid to be scientist, could have predicted the next massive meteor hitting Earth. Of course though, we wouldn't know, we wouldn't have any Earth, any McCain.

		<description>The &lt;strong&gt;economic rationale&lt;/strong&gt; for using federal dollars rather than paying for the projector privately: positive externalities that will be realized in the future due to the development of an interest in science (particularly among children).

In other words, I am all for private funding when the benefits accrued are private.  However, public funding is ok, when the benefits are society-wide.

Children who visit the Adler planetarium and are inspired to become scientists will not neccessarily live in Chicago once they grow up - more importantly the jobs that these children will create as scientists and the research they will do will help the country at large, not just the children themselves, or residents of Chicago.

The exact cost benefit calculations after considering externalities are far from trivial.  However the stock libertarian response demonstrates an insufficient understanding of the economic principles involved.</description>

		<description>Mari Womack, Ph.D -

You may be a scientist but you are also a troll with the whole "above Chirst" stuff. I also find you to be incredibly disingenuous.

One - The three wise men were astronomers? First we'll assume Christianity is more than just myth but actual truth. If we accept as a fact that the three wise men followed a star it makes them as much an astronomer as every astrologer out there, and you know that is a bit of a stretch.

Second - A planetarium has as much to do with teaching astronomy as a television special on "A Brief History of Time". Although at least that program is more than just pretty pictures.

Third - Chicago has 2.8 million residents as of 2005 (US Census approximation).  Why couldn't they manage to raise the money instead of asking for it from the federal government. Oh they could, but its hard to get elected when your setting aside 3 million from a city budget for a planetarium.</description>
