Los padres y los abuelos de Jorge Wagensberg, uno de nuestros intelectuales y divulgadores de la ciencia con más reconocimiento internacional, se libraron de la Segunda Guerra Mundial y del Holocausto en Polonia, pero tras su llegada a Barcelona sufrieron la Guerra Civil española. Estas memorias, que recogen tanto divertidas anecdotas como sugerentes reflexiones, tambien hablan de esta pequeña comunidad judia catalana.La Escuela Suiza y el Liceo Frances, con gallinas, clases de violin y los rios de Alemania; el lanzador de peso Bajerbe; los años del Bocaccio y el primer amor; la utilidad del esencial si-coma-pero y el espiritu critico; religiones, creencias y supersticiones; la Fundacion la Caixa y el CosmoCaixa... Historia, conocimiento y humor en las memorias de un hombre lucido y deslumbrante.Puestos a escribir la propia historia, la tentacion de mejorarla, aunque sea solo un poco, asoma cada dos por tres. He intentado concentrarme para contener este impulso, para que no haya ni siquiera un gramo de azucar añadido. Ni de vinagre. Paseando por la infancia uno se da de bruces con la ignorancia que uno tiene sobre si mismo. Se aprende mucho. Ha sido una sorpresa.

There is a manuscript of Maharsi Bharadvaja titled Amsu-bodhini (with a commentary of Bodhananda) at the library of Oriental Institute, Vadodara (Baroda). In the introductory passages, it is said that in the original text of Bharadvaja, the aphorisms of Amsu-bodhini are divided into twelve chapters having one thousand sections. In order to make it understandable, Bodhananda wrote a commentary on it. Actually the available manuscript is the first chapter of the work, having a commentary over the first 50 aphorisms of Maharsi Bharadvdja. The title of this chapter is Srstvadhikarah i.e. the Evolution of the Universe. Description of aphorisms in first chapter describes creation of Solar system.

The second law of thermodynamics is an example of the fundamental laws that govern our universe and is relevant to every branch of science exploring the physical world. This reference summarizes knowledge and concepts about the second law of thermodynamics and entropy. A verbatim explanation of chemical thermodynamics is presented by the author, making this text easy to understand for chemistry students, researchers, non-experts, and educators.

Electricity was the scientific fashion of the Enlightenment, an Entertainment for Angels, rather than for Men. Lecturers attracted huge audiences to marvel at sparkling fountains, flaming drinks, pirouetting dancers and electrified boys. Enlightenment optimists predicted that this new-found power of nature would cure illnesses, improve crop production, even bring the dead back to life. Benjamin Franklin, better known as one of Americas founding fathers, played a key role in developing the new instruments and theories of electricity during the eighteenth century. Celebrated for drawing lightning down from the sky with a kite, Franklin was an Enlightenment expert on electricity, developing one of the most successful explanations of this mysterious phenomenon. But Patricia Fara, Senior Tutor of Clare College Cambridge, reveals how the study of electricity became intertwined with Enlightenment politics. By demonstrating their control of the natural world, Enlightenment philosophers hoped to gain authority over society. And their stunning electrical performances provided dramatic evidence of their special powers.

One principal cause of the little attention paid to Entomology in this country, has doubtless been the ridicule so often thrown upon the science. The botanist, sheltered now by the sanction of fashion, as formerly by the prescriptive union of his study with medicine, may dedicate his hours to mosses and lichens without reproach; but in the minds of most men, the learned as well as the vulgar, the idea of the trifling nature of his pursuit is so strongly associated with that of the diminutive size of its objects, that an entomologist is synonymous with every thing futile and childish. Now, when so many other roads to fame and distinction are open, when a man has merely to avow himself a botanist, a mineralogist, or a chemista student of classical literature or of political economyto ensure attention and respect, there are evidently no great attractions to lead him to a science which in nine companies out of ten with which he may associate promises to signalize him only as an object of pity or contempt. Even if he have no other aim than self-gratification, yet "the sternest stoic of us all wishes at least for some one to enter into his views and feelings, and confirm him in the opinion which he entertains of himself:" but how can he look for sympathy in a pursuit unknown to the world, except as indicative of littleness of mind?

Los riesgos son connaturales a las sociedades modernas. Las amenazas relacionadas con los sistemas financieros, los sistemas políticos, las tecnologías de la información, el terrorismo, la seguridad alimentaria, las epidemias o los desastres naturales asociados al cambio climatico, entre muchas otras, demandan marcos metodologicos rigurosos para el analisis y la gestion de riesgos. De esto se encarga la disciplina global del analisis de riesgos, cuyos conceptos basicos se esbozan en este libro. En particular, incide en la necesidad de predecir adecuadamente la ocurrencia de las posibles amenazas a las que se enfrenta el sistema sobre el que se esta realizando el analisis, asi como predecir sus impactos, para despues integrar toda esta informacion en un marco coherente y riguroso que ayude a tomar las mejores decisiones en relacion con la gestion de riesgos. El objetivo sera reducir la probabilidad de que se produzcan las amenazas consideradas y, llegado el caso, tratar de minimizar su impacto. Los autores realizaran este recorrido por el analisis de riesgos apoyandose en ejemplos y casos que han ido analizando estos años en dominios como la ciberseguridad, la seguridad aerea, la epidemiologia, la seguridad nacional, el sector del seguro y los vehiculos autonomos.

Comprender del comportamiento del clima, es de interes en diversos sectores de la produccion. En este sentido, el libro presenta resultados de la investigacion que tenia como proposito describir la incidencia ejercida por el clima en los requerimientos de agua del cultivo de la papa en la region central de Boyaca. Para esto, se presenta un modelo que relaciona la intensidad, duracion y frecuencia de las lluvias (IDF), para describir y predecir el comportamiento de la precipitacion, a traves del analisis probabilistico de la informacion registrada en estaciones agroclimatologicas, ubicadas en la cuenca del rio de la region, donde predomina el cultivo objeto de estudio. Posteriormente, se determinan requerimientos de agua para el cultivo, del calculo y relacion entre: la evapotranspiracion del pasto (ETo), el coeficiente unico (Kc), la evapotranspiracion bajo condiciones estandar (ETc), el coeficiente dual (suma del coeficiente de la evaporacion (Ke) y de la transpiracion (Kcb)) y el coeficiente de estres hidrico. Finalmente, al implementar los modelos anteriores con la caracterizacion del tuberculo y los registros de una estacion agroclimatologica durante 51 anos; se describe el comportamiento del clima, los requerimientos de agua en los posibles periodos del cultivo en cada uno de estos anos y se identifican las epocas que presentaron condiciones climatologicas favorables o desfavorables. Con esta informacion y el modelo IDF se pueden establecer periodos de retorno de los eventos criticos de precipitacion que incidiran en los calendarios de siembra.
