Physica Generalis (1776).Physica Particularis (1770).Prologue to a 1776 copy of Physica Generalis
Horvath entered the Jesuit order at 19 years of age (17 October 1751) in Trencsén (
Trenčín), became a university professor, and subsequently authored the well-known
Latin textbooks Physica Generalis (1767/1782, 496pp) and Physica Particularis (1770/1782, 472pp).[1] Various other works are attributed to Horvath, including Elementa Physicae (1790/1807/1819, 656pp) which is a condensed revision of Physica Generalis and Physica Particularis, Institutiones Logicae (1767/1813, 118pp), Elementa/Institutiones Matheseos (1772/1782, 456pp), Institutiones Metaphysicae (1767/1817, 362pp) and Declaratio Infirmitatis Fundamentorum (1797, 188pp) which is a philosophical text regarding speculations on the nature of God posited by
Immanuel Kant.[2][3][4][5][6] This collection of works, including
metaphysics/
logic and physics, was typical of Jesuit academics teaching under the
Ratio Studiorum (1599).[7] The books were published in
Nagyszombat (Hungary),
Augsburg (Germany),
Eger and
Buda (Hungary), Velencze (Principality of Transylvania),
Madrid (Spain),
Vienna (Austria) and
Venice and
Turin (Italy), including multiple editions and/or printings of each volume.[8][9][10]
He was among the most important Central European physics textbook authors in the 18th century (see also
Andreas Jaszlinszky as well as
Leopold Biwald and
Joseph Redlhamer), and an innovative proponent of
Newtonian mechanics, which in hindsight was the correct theory rather than the
Cartesian mechanics popular among some
Continental philosophers.[12][13][14][15] By promoting the methods of
Copernicus and
Newton, influenced by the approach of Borgondio and
Boscovich, Horvath represents a (correct) departure from "accepted" thinking in that region of Europe, and his works were widely distributed.[16] He continued to publish and instruct students from a secular professorship after the Jesuit order was suppressed in 1773, and during his tenure the university faculty moved to modern-day Hungary (1777) to become the renowned
University of Budapest.[17][18][19]
Full-text scanned versions of Physica Particularis (1782/1775/1770/1817), missing some pages and illustrated plates, are available online.[20][21][22][23][24] Similarly, scanned copies of Physica Generalis (1780/1775/1772) are available online.[25][26][27] Images of the textbook title pages are also available.[28][29][30][31] Each of these textbooks is worth approximately $150 depending on condition.[32][33][34]
An example of near-contemporary notes regarding one of these textbooks is given below, where the reader is attempting to derive Prop 280 from Physica Generalis, involving the force on a body in a
circular orbit. The antiquated nomenclature includes [c = velocity] and [v = force] with [t = period] being normalized by 2π.
