An example of the existent specification of gravity is furnished by the following phenomenon: when a bar of iron, evenly balanced on its fulcrum, is magnetized, it loses its equilibrium and shows itself to be heavier at one pole than at the other. Here the one part is so affected that without changing its volume it becomes heavier; the matter ...
Aeneas, depicted here with Venus, was considered the embodiment of gravitas, pietas, dignitas, and virtus. [4]Gravitas was one of the virtues that allowed citizens, particularly statesmen, to embody the concept of romanitas, [5] which denotes what it meant to be Roman and how Romans regarded themselves, eventually evolving into a national character.

Before Newton’s law of gravity, there were many theories explaining gravity. Philoshophers made observations about things falling down − and developed theories why they do – as early as Aristotle who thought that rocks fall to the ground because seeking the ground was an essential part of their nature.

A Treatise Concerning the Principles of Human Knowledge (commonly called the Principles of Human Knowledge, or simply the Treatise) is a 1710 work, in English, by Irish Empiricist philosopher George Berkeley. This book largely seeks to refute the claims made by Berkeley's contemporary John Locke about the nature of human perception.
Depending on which features of general relativity and quantum theory are accepted unchanged, and on what level changes are introduced, [204] there are numerous other attempts to arrive at a viable theory of quantum gravity, some examples being the lattice theory of gravity based on the Feynman Path Integral approach and Regge calculus, [191 ...
General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example
Some then-accepted physical theories were inconsistent with that framework; a key example was Newton's theory of gravity, which describes the mutual attraction experienced by bodies due to their mass. Several physicists, including Einstein, searched for a theory that would reconcile Newton's law of gravity and special relativity.
Utilitarian Jeremy Bentham discussed some of the ways moral investigations are a science. [9] He criticized deontological ethics for failing to recognize that it needed to make the same presumptions as his science of morality to really work – whilst pursuing rules that were to be obeyed in every situation (something that worried Bentham).
