Tuesday, October 14, 2008 — The Notorious Overhead Projector

Ever won­der about that “three mil­lion dol­lar ear­mark for an over­head pro­jec­tor” that is such an impor­tant talk­ing point in John McCain’s elec­tion cam­paign? Accord­ing to an arti­cle in this week’s Sci­ence News, it turns out that the “over­head pro­jec­tor” is the Zeis star pro­jec­tor in the ven­er­a­ble Adler Plan­e­tar­i­um in Chica­go. Like the oth­er two major Amer­i­can plan­e­tar­i­ums in New York and Los Ange­les, the Adler must replace its fifty-year old instru­ment, which the orig­i­nal Ger­man man­u­fac­tur­er will no longer ser­vice. As with the oth­er two, the request for fed­er­al fund­ing is rou­tine, and no politi­cian would dream of vot­ing against it. The three plan­e­tar­i­ums teach the fun­da­men­tals of astron­o­my to mil­lions of urban school chil­dren who have nev­er seen a clear night star-filled sky, and are basic ameni­ties of major cities. The cost of a few mil­lion dol­lars amor­tized over half a cen­tu­ry is triv­ial. No politi­cian in any of the three states involved would have vot­ed oth­er­wise. Could any­thing bet­ter demon­strate the dis­hon­esty and the mind-bog­gling igno­rance of the McCain campaign?
