Vatican astronomer delivers commencement address

Guy Consolmagno, S.J., astronomer, teacher, physicist, researcher, and Jesuit, delivered the 2014 Georgetown College commencement address. In a speech urging graduates to never be afraid of the truth, and to never think that their comprehension of the truth is finished or complete, he wove in comments on dark matter, magnetic susceptibility, integration by parts, and extraterrestrials! The honorary degree citation and the speech can be viewed in the video of the College Commencement Ceremony.
