For example, if someone had 5 gallons of water and he loses one, he will choose to sacrifice his lower priority want to water his roses, before his highest priority want which is to sustain his life. In other words, if he has 5 gallons of water, the least valuable use in satisfying his wants for any given one of those gallons is the watering of his roses. This is the use that is on the “margin.” So the “marginal utility” of one gallon of water for him is the benefit he receives by watering his roses. In terms of applying this to prices, he will not be willing to sell one of his 5 gallons of water unless what he receives in return satisfies a greater want than the satisfaction he receives by watering his roses. If he had 10 gallons of water, naturally the marginal utility of water would be lower and he would be willing to sell it at a cheaper price. If he had an unlimited amount of water and kept it all to himself, any given gallon of water would have absolutely no usefulness to him. He is only able to drink so much water, and his roses can only handle so much water. So, he is willing to trade a gallon of water for things that are of any usefulness at all in order to increase the satisfaction of his wants. If money is in use, he would be willing to sell his water for any price that is above zero that others offer, so that he can purchase other things that satisfy still unmet wants; his water needs are already more than satified. Of course, the price that actually resolves also depends on the demand side. Demand is also determined by marginal utility. If an individual is wanting to buy one gallon of water, he will not trade something for a gallon unless the least satisfaction he receives from keeping that thing is lower than the satisfaction he will receive by having the gallon of water (note that he does not have to have a possession to trade, for he can trade one unit of his labor). If another object is substitued for water, such as gasoline, it would have a different marginal utility and thus a different price. The higher the marginal utility for all market participants as a whole, the higher the price.

Lux has artificial sunlight, water, and even day and night cycles. Denizens of Lux have come to call it The City and treat it as a sentient force. The landscape of the underground area is primarily desert. Initially the series is mostly concerned with the conflicts between the factions in Lux, but changes scale as the series goes on to look at the city’s interaction with the surface world. The central plot device is a method of creating prosthetic body parts, called “Texhnolyze.”

Es el proceso inverso de la entropía, y esta definido por el paso de un estado de desorden aleatorio a otro estado de orden previsible.

De hecho, todas las religiones de orden cosmogónico describieron la creación como un proceso del tipo negentrópico, como el paso de un estado de desorden indiferenciado a un orden organizado.

En relación con la información se puede decir que a mayor desorden o entropía, mayor es la cantidad de información necesaria para recuperar un mensaje.

À l’automne, période limite de la fermeture de la navigation saisonnière en méditerranée, il s’embarque à Ostie le 14 novembre 415, la via Aurelia lui semblant peu sûre par la présence des Goths qui ont détruit les ponts, rendant la route côtière difficilement praticable. Sous forme de poème, De reditu suo (Mon retour), il écrit le récit de son voyage par mer qu’il effectue en huit étapes sur environ deux semaines, suivant la route maritime suggérée par l’Itinerarium Maritimum, sorte de guide de la navigation en Méditerranée. Marseille est la destination probable de ce voyage maritime, dont le récit est interrompu à Luni (Carrare) aux premiers jours de décembre. Le reste est perdu.

Si ha invece con la redistribuzione dei benefici della seconda rivoluzione industriale alla parte meno abbiente della società. Non si tratta di un operazione di filantropia, ma della creazione di un mercato di acquirenti che da proletari diventano consumatori. Questo avviene infatti perché l’industria per giustificare la propria crescita ha bisogno di un mercato di consumatori crescente, ed è possibile proprio perché l’automazione della catena di produzione consente un abbattimento enorme dei costi di produzione e quindi dei prezzi al consumo, tale da consentire ad una fetta sempre più ampia di persone di accedere a beni prima riservati a pochi. (Un aspetto secondario, ma interessante, è che la riduzione dei tempi di lavorazione si concilia con il fatto che per consumare il lavoratore ha bisogno anche di tempo e quindi dalle quattordici ore (o più) in fabbrica della prima era industriale si scende alle 40 ore settimanali (o meno) di oggi.)
