La Milonga del Amor

Tango is a dance that has influences from European and African culture. Dances from the candombe ceremonies of former slave peoples helped shape the modern day Tango. The dance originated in lower-class districts of Buenos Aires and Montevideo. The music derived from the fusion of various forms of music from Europe. The word "tango" seems to have first been used in connection with the dance in the 1890s. Initially it was just one of the many dances, but it soon became popular throughout society, as theatres and street barrel organs spread it from the suburbs to the working-class slums, which were packed with hundreds of thousands of European immigrants, primarily Italians, Spanish and French.

In the early years of the 20th century, dancers and orchestras from Buenos Aires travelled to Europe, and the first European tango craze took place in Paris, soon followed by London, Berlin, and other capitals. Towards the end of 1913 it hit New York in the USA, and Finland. In the USA around 1911 the word "tango" was often applied to dances in a 2/4 or 4/4 rhythm such as the one-step. The term was fashionable and did not indicate that tango steps would be used in the dance, although they might be. Tango music was sometimes played, but at a rather fast tempo. Instructors of the period would sometimes refer to this as a "North American tango", versus the "Rio de la Plata tango". By 1914 more authentic tango stylings were soon developed, along with some variations like Albert Newman's "Minuet" tango.

In Argentina, the onset in 1929 of the Great Depression, and restrictions introduced after the overthrow of the Hipólito Yrigoyen government in 1930 caused tango to decline. Its fortunes were reversed as tango again became widely fashionable and a matter of national pride under the government of Juan Perón. Tango declined again in the 1950s with economic depression and as the military dictatorships banned public gatherings, followed by the popularity of rock and roll.

In 2009 the tango was declared as part of the world's "intangible cultural heritage" by UNESCO.

New 3D technology looks to the past to overcome the problems of present systems

Knowing of the problems with current 3D technologies, such as the noticeable dimming of the image, restricted viewing angle and even reports of people suffering headaches and nausea when watching for an extended peiod 3D images, German and Swiss researchers say they have developed a technology that overcomes these problems. The discovery is the result of three friends of the German company Infitec that hope to develop a 3D LCD flat screen capable of displaying full resolution of the new formats of high definition televisions.

Using a wavelength band of color more closely on the glasses, the company has been using specific wavelengths of red, green and blue for the right eye and different wavelengths of the same color for the left eye, thus providing different images for both eyes, giving the viewer the illusion of 3D.

Along with the Swiss company Optics Balzers, the Infitec secured funding to start developing a 3D LCD screen. While Infitec was responsible for research to better use of sign and lighting on the monitor and software for this, Optics Balzers has developed special filters for lighting and the glasses.

They decided to create a new optical design for the monitor, combined four LEDs - two green, one red and one blue - to create a range of colors they needed. The end result was a 23-inch monitor that the team calls Dualplex Display, which causes less strain on the eyes than other 3D technologies, the glasses do not darken the ambient light and screen can be viewed from all angles without distorting the images 3D.

The partners have applied to patent the screen in Germany and are in the process of submitting patents in other countries with the ultimate goal of selling the 3D LCD  households. Initially, though, they think they will find it easier to reach niche professional markets such as medical professionals - using 3D images to help surgeons doing operations.

Hi, my name is Jackson, I'm 26 years old, my birthday is on February 22, I was born and raised in Natal/RN with my father, my mother and my oldest brother. I studied at Hipócrates Zona Sul School since I was a boy, and I was an athlete of basketball while in there I studied. Today I am a student of last period of Bachelor of Science of Computer at UFRN. In my spare time I like spend hours on PC making my software's projects and accessing the internet, I love watch movies at home and in movie theater, and I also like listen to music and go out with my friends. I am shy, but when I am with my friends I can be very extrovert and playful. One of my hobbies is dancing, I dance Tango, Bolero, Forró, Gafieira's Samba and others, I go to the gym dance ever sartuday. I also collect board games, I currently have more than 30 games at home and always play with my friends, when possible. I love cooking and to eat all kind of foods.
 I work in the superintendence of informatic at UFRN, I am an analyst and programmer of the administrative system of the university, SIPAC. I like japonese culture, like anime and cosplays, and electronic games. Every year I go to events of this genre.
