No full textIn 1908 Edison increased the playing time of the cylinders. From 1888-1902 the speed of the records varied so the record could fit the song, anywhere from 90-144rpm. After 1902 the speed was standardized at 160rpm. In 1908 Edison cylinders changed from 100 grooves per inch to 200 grooves per inch. From 1908-1911 Edison Amberols were made, these are a wax cylinder record. And these play with only sapphire stili, on the Edison Reproducers model H,L,N, N56, Model M, K,O. In 1912 Edison invented the Blue Amberol, it is a 4 minute record but made of celluloid. These will play on all of the above reproducers plus the Diamond A,B,C,D on the Edison Amberola cylinder phonographs. Edison Blue Amberols were made from 1912-1929. Wax Amberols will not play wth the Diamond A,B,C,D. ; Musica

No full textFrom Pulitzer Prize-winning author Morris comes a revelatory new biography of Thomas Alva Edison, the most prolific genius in American historyThomas Alva Edison's invention of the first practical incandescent lamp 140 years ago so dazzled the world that it cast a shadow over his later achievements. In all, this near-deaf genius patented 1,093 inventions, not including those he left unlicensed for the benefit of medicine.Morris portrays the unknown Edison-- philosopher, futurist, chemist, botanist, wartime defense adviser, founder of nearly 250 companies-- while deconstructing the Edison of mythological memory. -- adapted from jacke

Adherence of Molecules to Silica Glass Surface: Experimental Results and Theoretical Calculations
No full textThe adherence of molecules to surfaces is used in a wide scope of technological applications. In this work we study the attachment of molecules onto porous silica glass surface obtained from a Vycor glass, after glassglass phase separation and leaching of the soluble phase with water. Nitrogen adsorption at 77 K was used for the determination of the specific surface area (BET area) and pore size distribution on the leached glass. The adherence onto the glass surface, of model molecules methylene blue (MB) and eosine yellow (EY), with positive and negative electrical charges respectively, was studied. The adsorption kinetics was determined from aqueous solutions using UV-VIS spectroscopy. It was found that the silica glass surface as prepared in of glass was found for methylene blue, and almost null adsorption for eosine yellow. First principles calculations were performed using the Density Functional Theory in order to model the interaction between both molecules and the glass surface.Fil: Rivera Figueroa, Edison.

No full textEn este trabajo relacionamos los conceptos de 3-mariposa y cristalización. El primero de naturaleza geométrica y el segundo de naturaleza topológica. Las 3-mariposas buscan estudiar los enlaces de 3-puentes y su clasificación. Las cristalizaciones estudian las 3-variedades de género dos y su clasificación. Las 3-mariposas pueden ser codificadas mediante una 6-tupla de enteros positivos de la forma {m₁,n₁,m₂,n₂,m₃,n₃} y las cristalizaciones se pueden codificar también con una 6-tupla de la forma (h₀,h₁,h₂;q₀,q₁,q₂). Todos estos enteros cumplen ciertas propiedades aritméticas sencillas.Doctorad
Thomas Edison: Success and Innovation through Failure [electronic resource] /
No full textThis book develops a systematic approach to the role of failure in innovation, using the laboratory notebooks of America's most successful inventor, Thomas Edison. It argues that Edison's active pursuit of failure and innovative uses of failure as a tool were crucial to his success. From this the author argues that not only should we expect innovations to fail but that there are good reasons to want them to fail. Using Edison's laboratory notebooks, written as he worked and before he knew the outcome we see the many false starts, wrong directions and failures that he worked through on his way to producing revolutionary inventions. While Edison's strengths in exploiting failure made him the icon of American inventors, they could also be liabilities when he moved from one field to another. Not only is this book of value to readers with an interest in the history of technology and American invention, its insights are important to those who seek to innovate and to those who employ and finance them.Chapter 1.

The importance of pairwork in educational and interdisciplinary initiatives
No full textAn early and prominent employee of Google, Georges Harik, recently made the assertion that pairs working together in startups are 20 times more productive than individuals working alone. The author has also personally experienced the boost of what is here termed pairwork in a university setting during the startup phase of several educational and interdisciplinary initiatives. The paper briefly explores pairwork in the history of technology and constructs both qualitative and little quantitative models of pairwork. The quantitative model under reasonable assumptions easily recovers Harik’s 20x boost. The paper also briefly examines the author’s recent experiences with pairwork in four interdisciplinary and educational initiatives
No Underskirts in Africa: Edison Carneiro and the "Lineages" of Afro-Brazilian Religious Anthropology
No full textThe article presents the folklorist, essayist, journalist and anthropologist Edison Carneiro (1912-1972) and situates him among the “lineages” or intellectual affiliations in the context of studies on Afro-Brazilian religious groups. Describing the life of Edison Carneiro, his relationship with American anthropologist Ruth Landes and his participation in the folkloric movement, I look to situate Carneiro among the various intellectual trends
found within the study of Afro-Brazilian religions. I argue that the author occupied an ambiguous position in terms of the African presence in the constitution of Afro-Brazilian religions, showing close proximities to Ruth Landes, Franklin Frazier, Ruth Benedict, Donald Pierson and Robert Park on the one hand, and Melville Herskovitz, Roger Bastide and Arthur Ramos on the other. Carneiro’s studies of Candomblé de Caboclo express this
