- Sententia (Wikipedia)
Sententiae, the nominative plural of the Latin word sententia, are brief moral sayings, such as proverbs, adages, aphorisms, maxims, or apophthegms taken from ancient or popular or other sources, often quoted without context. Sententia, the nominative singular, also called a “sentence”, is a kind of rhetorical proof. Through the invocation of a proverb, quotation, or witty turn of phrase during a presentation or conversation one may be able to gain the assent of the listener, who will hear a kind of non-logical, but agreed-upon truth in what one is saying. An example of this is the phrase “age is better with wine” playing off of the adage “wine is better with age”. The same saying is present in Luke 5,39.
- Electric charge (Wikipedia)
Electric charge (symbol q, sometimes Q) is a physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or negative. Like charges repel each other and unlike charges attract each other. An object with no net charge is referred to as electrically neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
