This reversibility of the dynamo was, according to a story frequently repeated, first discovered quite by accident.
Another thing most remarkable among those who worshiped by sacrifice in the early times, is that they believed firmly in the reversibility of merit, that is, that the innocent could atone for the wicked.
As we have said, it supposes the necessity of atonement and belief in the reversibility of merit.
Reversibility is an ideal and extreme case which cannot be realized, but which can be approximately attained in many circumstances.
It is true that certain mathematicians warn us that a mechanics can be devised in which reversibility would no longer be the rule, but the bold attempts made in this direction are not wholly satisfactory.
In physics, the contrary rule appears very general, andreversibility generally does not exist.
We all feel instinctively that there is something ridiculous and impossible about this idea of reversibility when applied to human beings.
Even the chemist and the physicist can effect this reversibility only to a limited extent and in special cases, as, for example, when energy is supplied from some external source.
Reversibility as a criterion of "perfection" of a heat engine.
The ideal engine was a very simple affair: but the notion of reversibility is difficult to express in a form sufficiently definite and precise.
It remains doubtful, however, whether this reversibilitycan explain all the synthetic processes in the cell.
These observations suggest the idea of reversibility of the process of differentiation of organs and tissues, in certain forms at least.
Thus by connecting a current with the poles of a Gramme dynamo it may be made to revolve, and, conversely, by rotating it an electrical current is produced, which demonstrates the reversibility of electricity into mechanical motion.
A number of methods have been invented to demonstrate the reversibility of spectra; among these methods we will cite two which are very easily carried out.
The fundamental condition for the application of Berthollet's doctrine, as well as Deville's doctrine of dissociation, lies in the reversibility of reactions.
Here again (see note 9) the reversibility is connected with the small heat effect, and again both reactions (direct and reverse) proceed at a red heat.
This reciprocity or reversibility naturally depends on the fact that all the phenomena of nature are only different kinds and forms of visible and invisible (molecular) motions.
It is of that type of motor in which the field magnet and armature poles are alternately arranged, and which requires a periodical reversibility of magnetism in the armature to cause the latter to revolve, as in the Griscom motor.
A further factor, namely, interpretation of the reversibility of our perceptions as due to their being conditioned by objects which stand in the relation of reciprocal determination, must first be postulated.
But even such reversibility of continuous series does not by itself establish coexistence.
A further step in this direction has been effected by the introduction of reversibility into a non-reversible case by means of a catalytic agent.
Such an introduction of reversibility is also possible by allowing sufficient time to permit the transformation to be produced by itself.
In this martyrdom threw a light upon the divine government of the world; and as the reversibility of guilt had formed the history of fallen man, so the reversibility of merit formed the history of man redeemed.
As the pendulum masses rise, the ratio of the limiting energy forreversibility to the total energy of the system becomes in fact smaller and smaller, until at the horizontal or position of maximum energy it reaches a minimum value.
Considered as a whole, there is evidently no aspect of reversibility about the operation, but it will be shown later (Sec.
The active or working energy is well within the limit for reversibility (Sec.
Stability of Energy Systems The ratio of the maximum or limiting energy for reversibility to the total energy of the system may vary in value.
This energy limit for reversibility is then imposed by the cohesive properties of the material or by its elastic limits.
The general working conditions of energy systems with respect to energy limits, stability, and reversibility (Sec.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "reversibility" in a variety of sentences. We hope that you will now be able to make sentences using this word.
