Curiosidad # 1 - Impactantes Imagenes de Polen Tomados Con Microscopio de Electrones
Este articulo del Telegraph tiene una excelente fotogaleria de imagenes electronicas del polen de diferentes plantas.
Hay fever sufferers can now see the face of their invisible enemy - thanks to these Scanning Electron Microscope images of pollen grains. A Swiss scientists named Martin Oeggerli, who uses the name Micronaut for his art, uses a Scanning Electron Microscope in his cellar to capture images of pollen grains. This picture shows a grain of willow pollen wedged between flower petals

Ademas, vean el transfondo de tomar estas microimagenes. No es con una camara de $5 de Walgreens y sin preparacion. Requiere conocimiento y practica. Mucha practica...
Curiosidad # 2 - Estatuas Griegas a Colores
Llega de Kottke esta nota relacionada a la practica historica de las estatuas griegas estar pintadas en colores vivos. En el pasado el Partenon debio estar lleno de color, no estar todo de blanco, marmol y yeso.

“Gods in Color: Painted Sculpture of Classical Antiquity” features full-size color reconstructions that challenge the popular notion of classical white marble sculpture, illustrating that ancient sculpture was far more colorful, complex, and exuberant than is often thought.
The reconstructions are the result of more than two decades of painstaking research by a pair of married German archaeologists, Vinzenz Brinkmann and Ulrike Koch-Brinkmann. The exhibition was organized by the Stiftung Archäologie and the Staatliche Antikensammlungen und Glyptothek of Munich, Germany, and has already been shown in a number of European cities. The Sackler is its first U.S. venue.
The Brinkmanns used various methods to detect the almost invisible traces of paint on the surfaces of the sculptures they studied. Among these was the use of raking light to reveal incised details as well as subtle patterns caused by the uneven weathering of different paints on the stone surface; ultraviolet (UV) light to bring out slight surface differences; and techniques such as X-ray fluorescence and infrared spectroscopy to analyze the types of pigments employed.
While not the first to notice the traces of color on ancient sculpture — scholars were arguing the case for painted classical sculpture as early as 1815 — the Brinkmanns are the first to bring the full armament of scientific equipment to the task.
The results are spectacular and reveal much about the way ancient Greeks and Romans viewed their world. Take, for example, the life-size figure of a Trojan archer from the temple of Aphaia on the Greek island of Aegina (excavated in 1811 and acquired by King Ludwig of Bavaria). The figure wears a shirt and leggings covered all over with an intricate red, yellow, blue, and green diamond pattern. Over this he wears a bright yellow vest inscribed with lions and griffins. A tall yellow hat with a flower pattern completes the costume.

Curiosidad # 3 - Robot Sparrow, otro webcomic
Habia posteado este webcomic de 10 paginas en mi FB durante mi primer turno aca en Biloxi, MS. Cobra resonancia estos dias porque aca estoy lejos de casa de nuevo. Triste de no poder haber asistido al funeral de mi suegro Angel, a quien tenia en muy alta estima. Tenia 98 a/nos. Escribo y trabajo, para no darle casco a su muerte que aunque esperada es como una espina en el corazon.
Bueno, estoy triste y en aceptacion. Cierro esta Nota 1 aqui, con Natural Blues de Moby. Aprovecho el hiato forzado para actualizar el blog y trabajar otros asuntos de la oficina de Puerto Rico. Por si falla el embed
