With text diagrams and 1 large folding plate. Original printed wrappers, minor fading and small tears to front cover. An excellent and very clean copy with some unopened pages, preserved in a clamshell box. First edition of van der Waals' classic dissertation on the continuity of gaseous and liquid states, and in which he introduced the "van der Waals equation" approximating the behavior of real fluids. This highly influential document, which changed the course of molecular physics, marked the beginning of a comprehensive molecular theory that was simplified using basic mechanics to explain the changes in states of liquids and vapors. Waals' "idea of continuity was that there is no essential difference between gaseous and liquid states of matter, although one must consider other factors in addition to motion of the molecules in the determination of the pressure. The important factors are the attraction between particles and their proper volume" (Weber, p. 41). This initial research led to his second great discovery of the law of corresponding states in 1880. Waals' work on the states of liquids and gases had a great influence on his contemporaries and engendered a huge body of derivative work. "One of the most important practical applications lies in the fact that the theory makes it possible to predict the conditions necessary for the liquefaction of a gas: thus it was of great assistance to Dewar in the liquefaction of hydrogen and to Kamerlingh Onnes in the liquefaction of helium. It also plays an important part in the theory of modern freezing technique" (Heathcote, p. 93). Waals (1783-1923) was awarded the Nobel Prize for physics in 1910 for his work on the equation of state of gases and liquids, introduced here. Elected to the Royal Netherlands Academy of Science and Letters in 1875 and then appointed chair of the department of physics at the University of Amsterdam in 1877, Waals was a highly respected educator who encouraged students to not only explore theoretical physics, but experimental as well.

Book Description A W Sijthoff., 1980. Paperback. Book Condition: Very Good. No Jacket. This is a 134 page A5-sized photographic reproduction of Van Der Waals' Doctoral Thesis, entirely in Dutch. The original work was published in 1873, but I've no idea of the date of this actual copy - I've recorded it as 1980 simply because I had to say something! A very good clean, clearly legible photocopy, unmarked in any way other than the owner's initials on the front cover, and complete with the fold-out drawing at rear. The complete title is "Over De Continuiteit Van Den Gas- En Vloeistoftoestand. Academisch Proefschrift, Ter Verkrijging van den Graad van Doctor in de Wis- En Natuurkunde, Aan de Hoogeschool Te Leiden, of Gezan Van Den Rector Magnificus Dr. M. De Vries,Hoogleerarin de Faculteit der Wijsbegeerte en Letteren, Op Zaterdag den 14den Juni 1873, des Namiddags Te 3 Uren, In Het Openbaar Te Verdedigen Door Johannes Diderik Van Der Waals, Geboren te Leiden.".
