Knowledge - Venn diagram

This Venn diagram sample illustrates the Plato's definition of knowledge. It was designed on the base of the Wikimedia Commons file: Belief Venn diagram.svg. [commons.wikimedia.org/ wiki/ File:Belief_ Venn_ diagram.svg]
"Justified true belief is a definition of knowledge that is most frequently credited to Plato and his dialogues. The concept of justified true belief states that in order to know that a given proposition is true, one must not only believe the relevant true proposition, but one must also have justification for doing so. In more formal terms, a subject S knows that a proposition P is true if and only if:
(1) P is true,
(2) S believes that P is true, and
(3) S is justified in believing that P is true" [Justified true belief. Wikipedia]

"A photooxygenation is a light-induced oxidation reaction in which molecular oxygen is incorporated into the product(s). ... Early studies of photooxygenation focused on oxidative damage to DNA and amino acids, but recent research has led to the application of photooxygenation in organic synthesis and photodynamic therapy.
Photooxygenation reactions are initiated by a photosensitizer, which is a molecule that enters an excited state when exposed to light of a specific wavelength (e.g. dyes and pigments). The excited sensitizer then reacts with either a substrate or ground state molecular oxygen, starting a cascade of energy transfers that ultimately result in an oxygenated molecule. Consequently, photooxygenation reactions are categorized by the type and order of these intermediates (as type I, type II, or type III reactions). ...
Photooxygenation reactions are easily confused with a number of processes baring similar names (i.e. photosensitized oxidation). Clear distinctions can be made based on three attributes: oxidation, the involvement of light, and the incorporation of molecular oxygen into the products" [Photooxygenation. Wikipedia]

"Sustainable development is an organizing principle for human life on a finite planet. It posits a desirable future state for human societies in which living conditions and resource-use meet human needs without undermining the sustainability of natural systems and the environment, so that future generations may also have their needs met.
Sustainable development ties together concern for the carrying capacity of natural systems with the social and economic challenges faced by humanity. " [Sustainable development. Wikipedia]
