Kopp contributed the general theoretical part, Kolbe the organic, and Buff and Zamminer the physico-chemical.
Physico-chemical properties have also been drawn upon to decide whether double unions are present in the benzene complex; but here the predilections of the observers apparently influence the nature of the conclusions to be drawn from such data.
This subject has occupied a dominant position in physico-chemical research since the investigations of van't Hoff and Arrhenius.
Guye has given a critical discussion of the relative accuracy of the gravimetric and physico-chemical methods, and favours the latter, giving for the atomic weight a value less than 14.01.
Hydrodynamical methods received increased attention and the investigation of the movements of the ocean by means of physico-mathematical devices developed as a result of the older work of Bjerknes, continued chiefly by Helland-Hansen and Sandstrom.
Phys., 1904, 14, 791; Tokyo Physico-Math.
It is to be noted that, whilst the zoological system took the form of a genealogical tree, with main stem and numerous diverging branches, the actual form of that tree, its limitation to a certain number of branches corresponding to a limited number of divergences in structure, came to be regarded as the necessary consequence of the operation of the physico-chemical laws of the universe, and it was recognized that the ultimate explanation of that limitation is to be found only in the constitution of matter itself.
Kopp devoted himself especially to physico-chemical inquiries, and in the history of chemical theory his name is associated with several of the most important correlations of the physical properties of substances with their chemical constitution.
The only work Kaempfer lived to publish was Amoenitatum exoticarum politico-physico-medicarum fasciculi V.
(1901); Kohlrausch, Practical Physics; Ostwald, Physico-Chemical Measurements.
A priori forms, according to Kant, are contributions of the mental powers of sense, understanding, and reason; but, according to Lange, they are rooted in " the physico-psychical organization."
217-248) included in the collection of scientific tracts published by Mersenne under the title Cogitata physico-mathematica in 1644, and a highly compressed statement of his psychological application of the doctrine of motion (L.W.
Among his other works are: Euclidis elementorum libri, &c. (Paris, 1626); Universae geometriae synopsis (1644); Les Mechaniques de Galilee (Paris, 1634); Questions inouies ou recreations des savants (1634); Questions theologiques, physiques, &c. (1634); Nouvelles decouvertes de Galilee (1639); Cogitata physico-mathematica (1644).
Walden point out from the physico-chemical standpoint that in water and hydrogen peroxide the oxygen atom is probably quadrivalent.
1713) published in his book Physico-Mechanical Experiments (1709), and in several Memoirs in the Phil.
To this professorship was added in 1887 the post of director of the physico-technical institute at Charlottenburg, near Berlin, FIG.
P. 551), Leonardo da Vinci must be considered as the discoverer of capillary phenomena, but the first accurate observations of the capillary action of tubes and glass plates were made by Francis Hawksbee (Physico-Mechanical Experiments, London, 1709, pp. 13916 9; and Phil.
Venturi, Essai sur les ouvrages physico-mathematiques de L.
"In its present form, and since the development of the mechanical theory of heat, the principle of the conservation of energy certainly seems to apply to the whole range of physico-chemical phenomena.
The same feeling led Socrates to abandon the old physico-metaphysical inquiries.
South-west of these buildings, on the other side of the Johannisthal Park, are clustered the medical institutes and hospitals of the university - the infirmary, clinical and other hospitals, the physico-chemical institute, pathological institute, physiological institute, ophthalmic hospital, pharmacological institute, the schools of anatomy, the chemical laboratory, the zoological institute, the physicomineralogical institute, the botanical garden and also the veterinary schools, deaf and dumb asylum, agricultural college and astronomical observatory.
Hence all natural research tends towards the form of a system of ends, and in its highest development would be a physico-theology.
