No mechanical explanation was found.
Closer examination of 19th-century physics shows that Newtonian ideas were already being undermined in many areas and that the program of mechanical explanation was openly challenged by several influential physicists toward the end of the century.
Newton himself adopted a pragmatic approach, deducing the consequences of his laws and showing how well they agreed with observation; he was by no means satisfied that a mechanical explanation was impossible, but he confessed in the celebrated remark "Hypotheses non fingo" (Latin: "I frame no hypotheses") that he had no solution to offer.
Nevertheless, the mechanical explanation is still uncertain since it has not yet been possible to attribute the causal link between the value of these biomarkers and the amount of physical activity.
The mechanical explanation is that inter-individual differences played the role of a 'noise' with an order of magnitude greater than individual imprecision, i.e., all the stimuli had a different rating at some point, thus the cores were void.
But his beautiful explanations of reflection and refraction far superior to those of Newton were entirely independent of mechanical explanations, being based solely on the so-called Huygens' principle of secondary wave fronts.
Although Huygens later rejected certain of the Cartesian tenets including the identification of extension and body, he always affirmed that mechanical explanations were essential in science, a fact that later was to have an important influence on his mathematical interpretation of both light and gravitation.
The first aspect of Newton's argument, it seems, is to indicate that mechanical explanations are predicated on referencing certain kinds of qualities when investigating natural phenomena, and that these qualities themselves are therefore not subject to mechanical explanation.
As germline cells should not be affected by mitotic recombination in the follicular epithelium, we were concerned that the GFP signal had disappeared for some other reason, and one possible explanation was mechanical damage.
Neither a special mechanism nor a mechanical explanation has been provided for this pathological process up to now.
A mechanical explanation model is introduced into the analysis to capture the force-displacement relationship inherent in and informative on the work system.
