Curious Physics

God's blessing discovered many things, which eventually gave him cause to publish various German and Latin writings original: Scripta, such as: Introduction to True and Unheard-of Physics original Latin: Introitum in veram atqve inauditam Physicam, The Concentrated Center of Nature original Latin: Centrum naturæ concentratum, Judgment on the Two Allied Hermetic Men original Latin: Judicium de Duum viris Hermeticis Fœderatis, and others more. Among these, however, my aforementioned late brother also wrote the present Curiosa Physica Curious Physical Matters while he was still the Personal Physician original: Leib-Medicus to the Elector Karl Karl I Ludwig, Elector Palatine (1617–1680), known for rebuilding Heidelberg after the Thirty Years' War., of most blessed memory, in Heidelberg, and was a Public Professor at the university there. He then sent this manuscript to me, as he was not inclined to have anything further printed; just as he, after this, while in the service of other great lords, did not submit anything else for publication. Therefore, this Curiosa Physica likewise remained with me until I was finally frequently requested by various curious patrons and friends to share it with everyone through printing. I have therefore finally seen fit to comply with them in this, especially as I do not see for what

reasons I should hold it back. I have also expanded and explained this little work here and there, now that it is being published for the second time—since the previous copies are already exhausted—particularly the 12th chapter on Salt. I have also appended various curious writings at the back, which were not previously in this little treatise. I considered it unnecessary to make it more extensive, lest it become an entirely different work. As short as this writing is, it shows itself to be just as curious and thought-provoking. May the kind reader accept it graciously and be left to the grace of God.
