Mathematical Models Quotes

• The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

• What distinguishes a mathematical model from, say, a poem, a song, a portrait or any other kind of "model," is that the mathematical model is an image or picture of reality painted with logical symbols instead of with words, sounds or watercolors.

• Las ciencias no tratan de explicar, ni siquiera de interpretar, sino que principalmente elaboran modelos. Por modelo se entiende una construcción matemática que, con el añadido de ciertas interpretaciones verbales, describe fenómenos observados. La justificación de tal construcción matemática es única y precisamente que se espera que funcione, es decir, que describa correctamente fenómenos de un ámbito razonablemente amplio.

• Modern economics is a set of formal models and equations purporting to fully determine human behaviour, at least in the economic realm. And there is no way that uncertainty can be compressed into determinate mathematical models.

• One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real. All one can do is find which mathematical models describe the universe we live in. It turns out that a mathematical model involving imaginary time predicts not only effects we have already observed but also effects we have not been able to measure yet nevertheless believe in for other reasons. So what is real and what is imaginary? Is the distinction just in our minds?

• If the system exhibits a structure which can be represented by a mathematical equivalent, called a mathematical model, and if the objective can be also so quantified, then some computational method may be evolved for choosing the best schedule of actions among alternatives. Such use of mathematical models is termed mathematical programming.

• The space that we're looking through is nine-dimensional. If you build a mathematical model, the amount of searching that we've done in 50 years is equivalent to scooping one 8-ounce glass out of the Earth's ocean, looking and seeing if you caught a fish. No, no fish in that glass? Well, I don't think you're going to conclude that there are no fish in the ocean. You just haven't searched very well yet. That's where we are.

• Durante demasiado tiempo, los economistas han intentado definirse a sí mismos en términos de sus métodos supuestamente científicos. De hecho, esos métodos se basan en un uso inmoderado de modelos matemáticos, que a menudo no son más que una excusa para ocupar el terreno y enmascarar la vacuidad del contenido.

• The good news is that, at least in economics, I've seen movement away from its overemphasis on mathematical models of purely rational behavior to a more eclectic and commonsense approach: research that is, among other things, more respectful of insights from psychology.

• La diferencia es que tenemos las pruebas más duras y dolorosas de que hubo un Holocausto. Pero, para el escenario del calentamiento global que está causando tanta histeria, sólo tenemos una película hecha por un político y modelos matemáticos cuyos resultados cambian drásticamente cuando se cambian algunas de las variables seleccionadas arbitrariamente.

• There is a history of mathematical models of oligopolistic competition dating from Cournot to the theory of games. There is also a literature generated by institutional economists, lawyers, and administrators interested in formulating and implementing public policy. It has been the tendency of these groups to work almost as though the other did not exist.

• Is war an inevitable outcome of competing interests in a complex society? In other words, would war be the same even if human nature were very different? There are mathematical models of large groups working together that lead to conflict on a reliable basis. So there's a whole other view of war that is not psychological at all.
