The centrosome or centrosphere is usually regarded as the dynamic centre of the cell and a special organ of division; but its absence in many groups of plants does not lend support to this view so far as plant-cells are concerned.
This tendency can be resisted by giving a twist to the torsion head and so applying to the movable coil through the spring a restoring torque, which opposes the torque due to the dynamic action of the currents.
Kekule answered Ladenburg by formulating a dynamic interpretation of valency.
Minuter accuracy of observation was inculcated by the labours and teaching of the great anatomists of the 17th century; and, for modern times, experimental physiology was instituted by Harvey, anatomy having done little to interpret life in its dynamic aspects.
But, whatever specific qualities it may have, it will still exist as an object, so long as it comes into dynamic relations with our minds.
Thus when in the ante-Nicene age the doctrine of the Trinity was under discussion, dynamic Monarchianism " regarded Christ as a mere man, who, like the prophets, though in a much higher measure, had been endued with divine wisdom and power"; modal Monarchianism saw in the Logos dwelling in Christ "only a mode of the activity of the Father"; Patripassianism identified the Logos with the Father; and Sabellianism regarded Father, Son and Spirit as "the roles which the God who manifests Himself in the world assumes in succession" (Kurtz, Church History, i.
If in a well-known passage (Logic § 212) he seems to countenance the Spinoxistic view he immediately corrects it by assigning an " actualizing force " to this illusion and making it a " necessary dynamic element of truth."
Its conception must become dynamic; there was need of some theory of development like J.
This, like all Droysen's work, shows a strongly marked individuality, and a great power of tracing the manner in which important dynamic forces worked themselves out in history.
That, however, complete conduction should arrive with alternations only ten times slower than light was an unexpected and remarkable fact, which verifies the presumption that the process of conduction is one in which the dynamic activities of the molecules do not come into play.
A gun may be considered a simple thermo-dynamic machine or heat-engine which does its work in a single stroke, and does not act in a series of periodic cycles as an ordinary steam or gas-engine.
Yet even on this point it learned something from the Stoics; the Neoplatonic conception of the action of the Deity on the world and of the essence and origin of matter can only be explained by reference to the dynamic pantheism of the Stoa.
This production is not a physical process, but an emission of force; and, since the product has real existence only in virtue of the original existence working in it, Neoplatonism may be described as a species of dynamic pantheism.
The first of these differences between the two systems is significant of the dynamic changes suffered by the Archean before the beginning of that part of the Proterozoic era represented by known formations.
The Cambrian formations have not been notably metamorphosed, except in a few regions where dynamic metamorphism has been effective.
Right is, therefore, at once the dynamic and the safeguard of progress.
Troostite and Sorbite, indeed, seem to be chiefly very finely divided mixtures of ferrite and cementite, and it is probably because of this fineness that sorbitic steel has its remarkable combination of strength and elasticity with ductility which fits it for resisting severe vibratory and other dynamic stresses, such as those to which rails and shafting are exposed.
The earliest thinkers down to Heraclitus endeavoured to find a material substance of which all things consist; Heraclitus, by his principle of universal flux, took a new line and explained everything in terms of force, movement, dynamic energy.
This self-strained frame is called the dynamic frame of the machine.
The driving and resisting efforts are represented by elastic links in the dynamic frame, and when the frame with its elastic links is drawn the stresses in the several members of it may be determined by means of reciprocal figures.
It accounts, too, for his polemic on the one hand against a Substantial Soul, a Buddhistic Absolute, an Infinite Spiritual Substance; on the other hand against the no less mysterious material or dynamic substratum by which naturalistic Monism explains the world.
It shows few traces of dynamic disturbance, but has been carved, mainly by erosion since the Miocene epoch, into many caverns, of which the Mammoth Cave is the largest.
The Stoic system is in brief: (a) materialism, (b) dynamic materialism, lastly (c) monism or pantheism.
His works, published wholly or in part since his death, are Elements of Dynamic (1879-1887); Seeing and Thinking, popular science lectures (1879); Lectures and Essays, with an introduction by Sir F.
The discovery of ether brought with it a reconstruction of our ideas of the physical universe, transferring the emphasis from the mathematical expression of static relationships to a dynamic conception of a universe in constant transformation; matter in equipoise became energy in gradual readjustment.
The school continued to grow and experienced ceaseless change.
It is an exaggeration of the theory which makes it an explanation of all human life, but the whole science of dynamic sociology rests upon the postulate of Marx.
Kant's position may be illogical as he himself 1 stated it; but it is the expression of a sound principle: we must connect it with his general tendency to recognize the dynamic side of things.
And thus in Philo's conception the Logos is much more than "the principle of reason, informing the infinite variety of things, and so creating the World-Order"; it is also the divine dynamic, the energy and self-revelation of God.
