Rhapsody in Blue

At http://www.archive.org/details/rhapblue11924 there is the original recording of Gershwin's Rhapsody in Blue.  This record was released soon after the piece was first performed (1924)  and soon replaced by an electrically recorded record.
Gershwin told his first biographer Isaac Goldberg in 1931: "It was on the train, with its steely rhythms, its rattle-ty bang, that is so often so stimulating to a composer – I frequently hear music in the very heart of the noise... And there I suddenly heard, and even saw on paper – the complete construction of the Rhapsody, from beginning to end. No new themes came to me, but I worked on the thematic material already in my mind and tried to conceive the composition as a whole. I heard it as a sort of musical kaleidoscope of America, of our vast melting pot, of our unduplicated national pep, of our blues, our metropolitan madness. By the time I reached Boston I had a definite plot of the piece, as distinguished from its actual substance."

Analogue audio - Cylinders and 78 rpm

"Phonograph cylinders were the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their era of greatest popularity (c. 1888–1915), these cylinder shaped objects had an audio recording engraved on the outside surface which could be reproduced when the cylinder was played on a mechanical phonograph. The competing disc-shaped gramophone record system triumphed in the market place to become the dominant commercial audio medium in the 1910s, and commercial mass production of phonograph cylinders ended in 1929" from http://en.wikipedia.org/wiki/Phonograph_cylinder
"Early disc recordings were produced in a variety of speeds ranging from 60 to 130 rpm, and a variety of sizes. From 1900, the two leading manufacturers of flat records were Columbia, which used 80 rpm as its speed, and Victor, which used 76.59 rpm. Since one company's records were playable on the other's machines, the standard speed became 78 rpm, which is around the average speed between the two. By 1925, the speed of the record became standardised at a nominal value of 78 rpm."
You can listen old cylinders and 78 rpms at http://www.archive.org/details/78rpm Internet Archive has a huge collection, quite interesting for researches on the modern music history.
rpm = revolutions per minute

Profiles - Duchess of Medina Sidonia

"Luisa Isabel Álvarez de Toledo was not only a novelist but also a historian, and lived in her palace in Sanlúcar with the most important private archive in Europe, said to be more than one million historical documents. She spent the latter years of her life cataloguing this legacy, in the residence where he ancestors have lived since 1297. The Duchess said in an interview in 2004 that the oldest document in the archive dates from 1128, and published a book ‘Africa versus America’ at the beginning of this decade, the result of years of exhaustive research of her own archive and others in Spain. In it, she challenged the official history that the Americas were discovered by Christopher Columbus, claiming that trade had been taking place across the Atlantic for centuries before the official ‘Discovery.’"

Centenario - Jose Maria Arguedas

2011, Centenario della nascita di Jose Maria Arguedas, here a poem

They say that we do not know anything
That we are backwardness
That our head needs changing for a better one

They say that some learned men are saying this about us
These academics who reproduce themselves
In our own lives

What is there on the banks of these rivers, Doctor?
Take out your binoculars
And your spectacles
Look if you can.
Five hundred flowers
From five hundred different types of potato
Grow on the terraces
Above abysses
That your eyes don't reach
Those five hundred flowers
Are my brain
My flesh

From: A call to certain academics by José María Arguedas, translated from the Quechua by William Rowe.

New Horizons in Space Missions

New Horizons is a NASA spacecraft mission currently moving toward Pluto. It is expected to be the firsts pacecraft to fly by and study this dwarf planet and its moons, Charon, Nix, and Hydra.
New Horizons was launched on January, 2006. It flew by Jupiter on February, 2007, and orbited Saturn on June, 2008. It will arrive at Pluto on July, 2015, after which it will continue into the Kuiper belt.
Pluto is the largest object of the Kuiper belt, which is the region of the Solar System extending from the orbit of Neptune (at 30 AU) to approximately 55 AU from the Sun. The belt consists mainly of small bodies, remnants from the Solar System's formation. It is the home to at least three dwarf planets – Pluto, Haumea, and Makemake. Some of the Solar System's moons, such as Neptune's Triton and Saturn's Phoebe, are also believed to have originated in the region.

W. Irving - The Legend of Sleepy Hollow

This evening the Legend of Sleepy Hollow, by Washington Irving.
"Another of his sources of fearful pleasure was to pass long winter evenings with the old Dutch wives, as they sat spinning by the fire, with a row of apples roasting and spluttering along the hearth, and listen to their marvellous tales of ghosts and goblins, and haunted fields, and haunted brooks, and haunted bridges, and haunted houses, and particularly of the headless horseman, or Galloping Hessian of the Hollow, as they sometimes called him. He would delight them equally by his anecdotes of witchcraft, and of the direful omens and portentous sights and sounds in the air, which prevailed in the earlier times of Connecticut; and would frighten them woefully with speculations upon comets and shooting stars; and with the alarming fact that the world did absolutely turn round, and that they were half the time topsy-turvy!"

Dumbledore, not Silente

A dumbledore is a bee (bombo). The Headmaster of Hogwarts, Albus Dumbledore, has a name showing one of the features of his character: as a bee in summer, he is always moving and his humming is pervading all the school. On the contary, the italian translation of the name in Albus Silente changes the character in authority and austerity.
