Resúmenes de matemáticas aplicadas a las ciencias sociales II con notas históricas


Book Description

PRÓLOGO En esta “colección” se produce una interesante colaboración entre las Matemáticas y su Historia, correspondiendo a Antonio Cipriano el desarrollo de los contenidos matemáticos (y el prólogo de este volumen) y a María José la búsqueda y puesta al día de las anotaciones históricas. Este libro, que aún no es un manual autosuficiente, comenzó su andadura de forma fragmentaria: por una parte, tenía yo diversos resúmenes de las unidades, por otra, abundantes relaciones de ejercicios y, por último, notas históricas sobre el desarrollo de algunos temas de la materia. Con el paso del tiempo reuní las dos primeras partes, porque me resultaba más cómodo para las clases, y empecé a trabajar ese prelibro con los alumnos. Como resultado de este trabajo reorganicé, añadí quité,… ideas diversas, a veces matices, o secciones completas… No ha sido hasta este año cuando a principio de curso decidí darle forma definitiva a todo el material y añadir las notas históricas que había redactado María José. Desde esta perspectiva, era para mí una experiencia nueva presentar a los alumnos un «libro» de matemáticas con reseñas históricas, y mi sorpresa ha sido mayúscula, porque ha tenido muy buena acogida entre ellos y, aunque por las exigencias de la programación no todas las reseñas se han podido leer y comentar en clase, creo que su inclusión ha sido un acierto, pues los alumnos a medida que las leían comentaban algunos datos o detalles curiosos, y su interés me animaba a leer más sobre la Historia de las Matemáticas (que me entusiasma) y a María José a documentarse y escribir más apartados apasionantes en los que se narran algunos acontecimientos de la historia matemática y se habla de sus creadores: los matemáticos, «esa especie de seres raros a los que les gusta llenar pizarras y hojas en blanco de símbolos que, en general, para el resto de los seres no dejan de ser signos sin sentido y sobre todo a los que no se les ve una utilidad clara»; y de las ideas: los conceptos matemáticos.







Without Criteria


Book Description

A Deleuzian reading of Whitehead and a Whiteheadian reading of Deleuze open the possibility of a critical aesthetics of contemporary culture. In Without Criteria, Steven Shaviro proposes and explores a philosophical fantasy: imagine a world in which Alfred North Whitehead takes the place of Martin Heidegger. What if Whitehead, instead of Heidegger, had set the agenda for postmodern thought? Heidegger asks, “Why is there something, rather than nothing?” Whitehead asks, “How is it that there is always something new?” In a world where everything from popular music to DNA is being sampled and recombined, argues Shaviro, Whitehead's question is the truly urgent one. Without Criteria is Shaviro's experiment in rethinking postmodern theory, especially the theory of aesthetics, from a point of view that hearkens back to Whitehead rather than Heidegger. In working through the ideas of Whitehead and Deleuze, Shaviro also appeals to Kant, arguing that certain aspects of Kant's thought pave the way for the philosophical “constructivism” embraced by both Whitehead and Deleuze. Kant, Whitehead, and Deleuze are not commonly grouped together, but the juxtaposition of them in Without Criteria helps to shed light on a variety of issues that are of concern to contemporary art and media practices.




Didactical Phenomenology of Mathematical Structures


Book Description

The launch ofa new book series is always a challenging eventn ot only for the Editorial Board and the Publisher, but also, and more particularly, for the first author. Both the Editorial Board and the Publisher are delightedt hat the first author in this series isw ell able to meet the challenge. Professor Freudenthal needs no introduction toanyone in the Mathematics Education field and it is particularly fitting that his book should be the first in this new series because it was in 1968 that he, and Reidel, produced the first issue oft he journal Edu cational Studies in Mathematics. Breakingfresh ground is therefore nothing new to Professor Freudenthal and this book illustrates well his pleasure at such a task. To be strictly correct the ‘ground’ which he has broken here is not new, but aswith Mathematics as an Educational Task and Weeding and Sowing, it is rather the novelty oft he manner in which he has carried out his analysis which provides us with so many fresh perspectives. It is our intention that this new book series should provide those who work int he emerging discipline of mathematicseducation with an essential resource, and at a time of considerable concern about the whole mathematics cu rriculum this book represents just such resource.

LEV


Book Description




The Rebel


Book Description

The Rebel is the memoir of a revolutionary woman, Leonor Villegas de Magnon (1876-1955), who was a fiery critic of dictator Porfirio Diaz and a conspirator and participant in the Mexican Revolution. Villegas de Magnon rebelled against the ideals of her aristocratic class and against the traditional role of women in her society. In 1910 Villegas moved from Mexico to Laredo, Texas, where she continued supporting the revolution as a member of the Junta Revolucionaria (Revolutionary Council) and as a fiery editorialist in Laredo newspapers. In 1913, she founded La Cruz Blanca (The White Cross) to serve as a corps of nurses for the revolutionary forces active from the border region to Mexico City. Many women like Villegas de Magnon from both sides of the border risked their lives and left their families to support the revolution. Years later, however, when their participation had still been unacknowledged and was running the risk of being forgotten, Villegas de Magnon decided to write her personal account of this history. The Rebel covers the period from 1876 through 1920, documenting the heroic actions of the women. Written in the third person with a romantic fervor, the narrative interweaves autobiography with the story of La Cruz Blanca. Until now Villegas de Magnon's written contributions have remained virtually unrecognized - peripheral to both Mexico and the United States, fragmented by a border. Not only does her work attest to the vitality, strength and involvement of women in sociopolitical concerns, but it also stands as one of the very few written documents that consciously challenges stereotyped misconceptions of Mexican Americans held by both Mexicans and Anglo-Americans.
