    Exclamation El verdadero tamaño de Mexico y del Mundo : Mapa de Peters.

    The Peters Projection World Map is one of the most stimulating, and controversial, images of the world. When this map was first introduced by historian and cartographer Dr. Arno Peters at a Press Conference in Germany in 1974 it generated a firestorm of debate. The first English-version of the map was published in 1983, and it continues to have passionate fans as well as staunch detractors.

    The earth is round. The challenge of any world map is to represent a round earth on a flat surface. There are literally thousands of map projections. Each has certain strengths and corresponding weaknesses. Choosing among them is an exercise in values clarification: you have to decide what's important to you. That is generally determined by the way you intend to use the map. The Peters Projection is an area acurate map.

    Mercator's projection (created at a time when navigators were sailing on the oceans in wooden ships, powered by the wind, and navigating by the stars) was particularly useful because straight lines on his projection were lines of constant compass bearing. Today the Mercator projection still remains useful for navigational purposes and is referred to by seafarers and airline pilots.

    The Mercator is also a "conformal" map projection. This means that it shows shapes pretty much the way they appear on the globe. The mapmaker's dilemma is that you cannot show both shape and size accurately. If you want a true shape for the land masses you will necessarily sacrifice proportionality, i.e., the relative sizes will be distorted.

    Algo que hacía de chavito era ver el área de México y "meter" a otros países dentro a ver si cabían. SI no cabían veía si eran más ricos y si cabían me enojaba porque siendo más grandes que otros nosotors no somos ricos.

    Es un teorema la imposibilidad de proyectar una esfera sobre un plano de tal forma que la proyección conserve distancias y ángulos...

    Cualqueira que haya tratado de envolver una manzana con una hoja de papel lo sabe...

    Se pueden hacer mapas que cnserven las distancias, pero sin conservar ámgulos...

    Y viceversa...

    Curiosamente el mapa usual, el mapamundi, no conserva ni didtancias ni ángulos...

    ¿porqué, entonces, se usa tanto?...

    Porque conserva la orientación relativa...

    Es decir, lo que en el mapamundi se ve al norte, realmente esta al norte...

    Aunque nos ha distoricionado la visión que tenemos del planeta (agranda las cosas cercanas a los polos, haciendo gigantescas a islas como Greolandia o Australia, por ejemplo), esa cualidad de mantener las orientaciones relativas es invaluable...


    El 99% de la gente cree que piensa, cuando en realidad solo reciclan sus prejuicios...
