He received his doctorate in 1825 after only three years study and returned to Brussels. There he worked on the theory of numbers, and, influenced by Quetelet , he became interested in social statistics. He had been intending to publish the complete works of Euler but he became more and more interested in social statistics. In 1829 Verhulst published a translation of John Herschel 's Theory of light. However he became ill and decided to travel to Italy in the hope that his health would improve. In 1830 Verhulst arrived in Rome. However his visit there was not a quiet one. Quetelet wrote:- Whilst on a trip to Rome he conceived the idea of carrying out reform in the Papal States and of persuading the Holy Father to give a constitution to his people. This plan did not meet with approval and Verhulst was ordered to leave Rome. He returned to Belgium.

Branch of Science Mathematicians Nationality Belgian Verhulst, Pierre-Francois (1804-1849) This entry contributed by Margherita Barile Belgian mathematician who introduced the Verhulst equation (also known as the logistic equation ) to model human population growth in 1838. He quit his literary studies to devote himself to mathematics. As an undergraduate at the University of Ghent, he was awarded two academic prizes for his works on the calculus of variations Later, he published papers on number theory and physics. The Belgian revolution of 1830 and the invasion of his country by the Dutch army in 1831 partially diverted his attention from abstract research. His political initiatives failed, nonetheless he could pursue his interests for social issues as a mathematician and a teacher. His interest in probability theory had been triggered by a new lottery game, but he soon applied it to political economy and later to demographical studies, a field that was rapidly developing due to Malthus' theory and the increasing use of statistics in human sciences. Verhulst, however, opposed any attempt to apply mathematical models to ethical judgement. His main work is References Quetelet, A. "Pierre-François Verhulst." in

But the baby can grow only as large as the uterus can hold; thus other factors start slowing down the increase in the cell count, and the rate of growth slows (but the baby is still growing, of course). After a suitable time, the baby is born, and the child keeps growing. Ultimately, the cell count is stable; the person's height is constant; the growth has stopped, at maturity.

Population Dynamics Population growth can be calculated by a number of mathematical models. The two simplest models are the Malthusian, or exponential model, and the Verhulst, or logistic model. The Verhulst Model, named after Pierre-Francois Verhulst (1804-1849) of Belgium, improved upon the exponential growth model of Malthus by incorporating a limiting population value that the environment can support. Above this value, lack of food or other resources causes the death rate to rise so that it equals the birth rate. It does not account for oscillations that may occur when food runs out suddenly, but is otherwise quite accurate, and has been shown to give a close match to real populations. The Malthusian equation assumes that population growth is proportional to the current population. x'(t) = bx(t) where b is the net growth rate per unit time and x is the population. This integrates to the familiar exponential x(t) = x * exp(bt) In the Verhulst model, competition occurs among individuals when they encounter other members of the population. This adds a quadratic term to account for the interactions between pairs of people, changing the differential equation to x'(t) = bx(t) - dx where b and d are unknown constants. After integration (which is left as an exercise for the reader to carry out on some rainy day) we get

CMSE Online Front Page CMSE Online Features Index Boom and Bust Mathematics It's the summer of 1997: rabies is devastating rabies populations in the Triangle. Although this troubling disease certainly seems like something out of the ordinary, the mathematics predicts that wild swings in populations are possible even in the most normal of times. The mathematics involved is amazingly simple. The founder of population mathematics was Pierre Verhulst (1804-1849), a very talented Belgian mathematician dogged by poor health throughout his short life. Prior to his work, the famous British economist Robert Malthus had predicted that animal and human populations were fated to grow exponentially. But Verhulst understood that real populations are capped: in every habitat and for every species there is a carrying capacity . A population exceeding this capacity must go down rather than up. Verhulst reasoned something like this. Let's write p(n) for the population in year n and let M be the carrying capacity. The population grows at a rate g, a certain percentage per year, as animals are born or wander into the area. (For big, long-lived species like humans g will be small, like 5%, but for most small, short-lived animals it will be much larger, usually more than 100%.) The population grows every year by gp(n) animals.

Verhulst Model of Population Growth (Note: This essay could also be used as a lesson on modeling logistic function) The logistic model was developed by Belgian mathematician Pierre Verhulst (1838) who suggested that the rate of population increase may be limited, i.e., it may depend on population density R=Ro(1-n/k) Before we move on to illustrate Verhulst's model, we first must understand the dynamics of the population. Population growth rate declines with population numbers, N, and reaches when N = K. Parameter K is the upper limit of population growth and it is called carrying capacity. It is usually interpreted as the amount of resources expressed in the number of organisms that can be supported by these resources. If population numbers exceed K, then population growth rate becomes negative and population numbers decline. The dynamics of the population is described by the differential equation: To illustrate this, we could form a simulation to explore how population is effected and how we can model the logistic function by Verhulst.

Light, an all-pervasive feature of modern culture, was not an automatic given in the Middle Ages. To have light at night represented advanced cultural development and financial wealth. Peasants, for instance, or regular workers, went to bed after the sun had set, and rose again at the crack of dawn. Today, electricity has changed all that, and nightlife is just as important as day life in many respects. When electricity fails, however, modern life quickly comes to a standstill. Man's instinctual fear of sudden darkness indicates the cultural significance of night at all times, and history can actually be written by focusing on human responses to night and darkness. These basic observations make Night in the Middle Ages an interesting study.

Why logistic ogive and not autocatalytic curve?, J Linacre We call our S-shaped response curve a logistic ogive. How did this term originate? S-shaped curves are also called sigmoid curves, from the Greek "s", sigma. In his "Mathematical Researches into the Law of Population Growth Increase" (Nouveaux Memoires de l'Academie Royale des Sciences et Belles-Lettres de Bruxelles, 18, Art. 1, 1-45, 1845), Pierre Francois Verhulst (1804-1849), Professor of Analysis at the Belgian Military College, examines population growth in Belgium. He discovers that sigmoid curves are useful for describing population growth. Following Malthus, Verhulst hypothesizes that small populations increase geometrically, because the supply of resources exceeds demand. Then, as supply and demand balance, population growth is constant. Finally, as demand exceeds supply, population growth decreases at the same rate that it had increased. Verhulst describes this process with an equation that enables him to predict when a population will reach any given size (see Verhulst's Figure): t = log10( p/ ( m/n - p ) ) / m where, for Belgium, with 1830 population of 4,247,113

Logistic equations are ones that are iterated (calculated over and over), recursive (output of the last calculation is input for the next), and normalized (population size ranges from zero - extinction - to one - maximum conceivable population).
