Thomas Robert Malthus (1766 - 1834) was a British economist and demographer, particularly famous for his pessimistic outlook but very influential. Although it is popularly assumed that their pessimistic thesis gave economics the nickname of the dismal science (dismal science), the phrase was actually coined by racist historian Thomas Carlyle in reference to an essay against slavery written by John Stuart Mill. For Malthus, the difference between social classes was an inevitable consequence. The poverty and suffering were the destination for the vast majority of people. The Malthusian theory was used in the Club of Rome for the preparation of the document "The Limits to Growth". Source: GNU Free Doc License, www.wikipedia.org In October 1838, Darwin read Thomas Malthus's book, published in 1798, related to population growth. In Malthus book explains that there is a strong error between the growth of the population and food production. His conclusion was that populations increase at a faster pace than the growth rate of food production (PG X PA). It would be impossible to feed all the beings of future generations. In order to understand the reasoning of Malthus will work with two problematic situations. One that involves PG (geometric progression) and another involving PA (arithmetic progression). After, we will do an exercise in understanding, assessing to what extent proved true theory of Malthus. Trying to understand the concept of PG It is our understanding that the formation of the embryo is initiated by a cell called egg or zygote. Our organism takes shape from the cell division where the first cell generates two, the two generating four, and so on. To better understand this division that occurs according to the mathematical concept of PG, we will complete the following table? Suppose at first was the conception of life and the second time it happened the first cell division. ACTIVITY Table 1 Note the column "Total cells". Mathematical regularity that exists? In the twenty-fifth time, how many cells have? What will be the total cells of the fiftieth time? Express your idea about PG.

Thomas Robert Malthus (1766 - 1834) bio je britanski ekonomist i demografi, osobito poznat po svojoj pesimističan outlook, ali vrlo utjecajan. Iako je uvriježeno je pretpostaviti da će njihov rad pesimistični dao Ekonomija nadimak tužan znanosti (turobno znanost), izraz je zapravo skovao rasističke povjesničar Thomas Carlyle je u odnosu na eseju protiv ropstva napisao John Stuart Mill. Za Malthusa, razlika između društvenih slojeva bio neizbježna posljedica. Siromaštvo i patnja su odredište za veliku većinu ljudi. Maltuzijanskog teorija je korišten u Rimskog kluba za izradu dokumenta "Granice rasta". Izvor: GNU Free License Doc, www.wikipedia.org U listopadu 1838 Darwin pročitati Thomas Malthus knjigu, objavljenu 1798, koja se odnosi na porast broja stanovnika. U knjizi Malthus objašnjava kako postoji jaka pogreška između rasta stanovništva i proizvodnje hrane. Njegov zaključak je da populacija povećati na bržim tempom od stope rasta proizvodnje hrane (PG X PA). Bilo bi nemoguće nahraniti sve bića budućim generacijama. Kako razumjeti rezoniranje Malthusa će raditi s dva problematičnim situacijama. Jedan koji uključuje PG (geometrijska progresija) i još uključuje PA (aritmetička progresija). Nakon, mi ćemo učiniti vježbe u razumijevanju, procjenu u kojoj mjeri dokazala istinsku teoriju Malthusa. Pokušavajući razumjeti koncept PG To je naše razumijevanje da formiranje embrija je inicirao ćeliji zove jaje ili zigota. Naš organizam se oblikuje na diobu stanica u kojoj je prva stanica generira dvije, dvije proizvodne četiri, i tako dalje. Da bi bolje razumjeli ovu podjelu koja se pojavljuje u skladu s matematičkim konceptom PG, dovršit ćemo sljedeću tablicu? Pretpostavimo, na prvom je koncept života, a drugi put se to dogodilo prvi diobu stanica. AKTIVNOST Tablica 1. Napomena rubrici "Ukupno stanice". Matematički regularnost koja postoji? U dvadeset i peti put, koliko stanica ima? Što će biti ukupni stanice pedeseti put? Izrazite svoje ideje o PG.
