In 1920, the Lambeth Conference repeated its 1908 condemnation of contraception and issued `` an emphatic warning against the use of unnatural means for the avoidance of conception, together with the grave dangers -- physical, moral, and religious -- thereby incurred, and against the evils which the extension of such use threaten the race ''.

The concept of unity, in which positive and negative are attributes of the same force, in which good and evil are relative, ever-changing, and always joined to the same phenomenon -- such a concept is still reserved to the physical sciences and to the few who have grasped the history of ideas.

The term also broadly refers to any enterprise that is potentially fraught with physical, financial or psychological risk, such as a business venture, a love affair, or other major life undertakings.

Early mathematicians regarded axiomatic geometry as a model of physical space, and obviously there could only be one such model.

Any information may be conveyed by an analog signal ; often such a signal is a measured response to changes in physical phenomena, such as sound, light, temperature, position, or pressure.

Animism encompasses the beliefs that there is no separation between the spiritual and physical ( or material ) world, and souls or spirits exist, not only in humans, but also in all other animals, plants, rocks, geographic features such as mountains or rivers, or other entities of the natural environment.

Among Classical Greeks, amazon was given a popular etymology as from a-mazos, " without breast ", connected with an etiological tradition that Amazons had their left breast cut off or burnt out, so they would be able to use a bow more freely and throw spears without the physical limitation and obstruction ; there is no indication of such a practice in works of art, in which the Amazons are always represented with both breasts, although the left is frequently covered ( see photos in article ).

One of the significant parts in aeronautics is a branch of physical science called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft.
