Three papers on physics and astronomy gathered by fifteen-year-old Joseph von Penckler, while still a student at the Theresan Military Academy near Vienna. Penckler, who would later become a Lower Austria government functionary and famous debtor, here writes a short presentation to the important scientific papers, obsequiously dedicated to the Maria Theresa Walburga Amalia Christina, ruler of the Hapsburg dominions. The first two papers, by Jesuit polymath Roger Josef Boscovich, and his student, the Fermo mathematician Carlo Benvenuti, are on the nature of light; the third, and most important, is Boscovich's dissertation confirming the absence of an atmosphere on the moon. The three papers were originally published in 1748, 1753, and 1761 respectively. A most interesting collection, organized according to the very young Penckler's course of study at the Vienna academy, and published to gain favor with the Empress.
