Beauty: Defining beauty, a critical old doctrine suggests it should be viewed without lust. Yet, lust is life itself!
Stupidity: Stupidity, the philosopher

Understanding Metals and Plastics: Properties & Processes
Metals
Metals are usually obtained from the transformation of minerals, which are rocks extracted directly from nature.
Some metals, such as gold, silver, platinum, and copper, can be found in their purest form and are called native metals.
Physical Properties
Electrical conductivity is the property that allows the passage of electrical current.
Thermal conductivity is the property of materials to transmit heat.
Density is the amount of material mass per unit volume.
Expansion is the relative variation

Evolutionary Theory and Evolutionary Psychology
Darwin
Darwin proposed the first evolutionary theory to explain how change might take place over time, especially how seemingly purposeful or functional structures might have arisen.
Adaptation
Improbably usefulness (too precisely functional to have arisen by chance only).

Spanish Ballads: History, Origin, and Classification
Old and New Ballads
Ballads: This is the name given to a collection of old ballads of the fifteenth-century romances, which includes the medieval epic tradition (from the ancient epic poems) and some other compounds in the fourteenth century.
