Freefall sound barrier exceeds

"I think they've dropped 20 tons on my shoulders. I prepared for this for seven years" said Austrian German ServusTV canal, in his first interview after the jump.



Los Angeles. AFP. - The Austrian skydiver Felix Baumgartner yesterday managed to break the sound barrier in free fall after successfully performing a jump record from just over 39,000 feet above the floor of New Mexico (southeastern United States).
Baumgartner, 43, achieved the fastest free fall in history to reach a speed of 1,137 km / h (the sound barrier is broken the 1,100 km / h, editor's note) during the 4 minutes and 19 seconds before parachute opening, said spokeswoman Sarah Anderson mission. This means that in addition to breaking the 1.24 times exceeded

Referring to an old problem that nearly forced him to abort at the last minute, Baumgartner said, "even on a day like this to start as well, a little mistake can happen. But I finally decided to jump. And it was the right decision, "he said.

Recalling the words of Neil Armstrong first set foot on the moon, the Austrian skydiver said: "Sometimes you have to go until you realize how small you are."

During ascent in a capsule powered by a balloon drop and eight minutes later, the Austrian beat several brands: the biggest rise in a manned balloon, jumping from from a greater height, yet belonging to former colonel Joe Kittinger U.S. Air Force (31,333 meters in 1960) and the breaking of the sound barrier.

However, could not break the mark of the longest free fall since its 4 minutes 19 seconds fell short of the 4 minutes 36 seconds of Kittinger. One of the first people who was congratulated President of Austria Heinz Fischer.

Serge Haroche ganó Nobel por ''domesticar'' átomos y luz

"We tried to study the simplest possible interaction between matter and light, between atoms and photons''


PARIS, FRANCE (09/OCT/2012.) - Frenchman Serge Haroche, said today after learning that he had been awarded the Nobel Prize for Physics 2012 that his scientific investigations consist essentially of "tame" the atoms and light.
"We intend to study the simplest possible interaction between matter and light, between atoms and photons," said Haroche news conference in Paris, still overwhelmed by the media frenzy of his award, he confessed.

Her research and those of his colleague and friend David Wineland American, who shares the prize of the Royal Swedish Academy of Sciences, have achieved "best isolate the atoms and photons to avoid disturbances" and to study them properly.
Cooled atoms and photons in order to reduce their speed and catch them in an electromagnetic field without destroying them, said the thirteenth French Nobel Physics in the College of France, where he is a professor.

This scientist, 68, likes to explain that the photon is like the soldier who dies Marathon after delivering his message, except through their research, the messenger particle (photon) survives.

His research opens the door to the development of quantum computers, much more powerful and faster than the current, the field called quantum information and communication.

However, Haroche confesses that it is "skeptical about the operation of the quantum computer, the way I think today" and although he believes that they will see the light in the future, no one dares to outline how and when.

Alternatively, however, provide examples of applications derived nearest his working field as atomic clocks running ions and achieve timing with high accuracy and enabling, among other things, operation of the GPS device.

French born in Casablanca (Morocco) in 1944, the new Nobel, has managed to manipulate photons as no one before him had done and his experiments have allowed to unpublished measurements in quantum physics to get those light particles trapped between two mirrors and measure their behavior without destroying them.

The specialist in quantum optics and quantum information science, also cherishes a long career as a teacher, so remember that "winning research today is the fruit of many years of work (...) as a team" and encourages new generations interested in science.

"It is essential to attract bright young people to careers in science, basic research. But lead them to a trap, but a career that allows them to have a normal life" for what to "simplify bureaucracy and prevent youth spend too much time looking for money for research and less to his scientific work, "he said.

EL ÉTER......Definiciones, canciones y poesía


  1. ¿Qué será eso del éter?
    Tantas veces nombrado....tantas veces cuestionado....el éter.....
    Desde épocas remotas se busca definirlo y en tantas otras dejado de lado.... sólo tomado en cuenta cuando es útil para explicar ciertos hechos, cotidianos o no. Científicos, artistas, poetas y cantantes lo mencionan y utilizan para caracterizar ciertos hechos o sentimientos que de otra manera serían difíciles de explicar....

    He aqui una definición dónde se lo menciona en relación al texto trabajado en este blog:

    Ether
    The ether is a hypothetical thing that was invented to explain the phenomena of light. Light is theoretically due to transverse vibrations of the ether. Since the days of Young the conception of the ether has extended, and now light, "radiant heat," and electricity are all treated as phenomena of the ether. Electrical attraction and repulsion are explained by considering them due to local stresses in the ether; magnetic phenomena as due to local whirlpools therein. The ether was originally called the luminiferous ether, but the adjective should now be dropped. Its density is put at 936E-21 that of water, or equal to that of the atmosphere at 210 miles above the earth's surface. Its rigidity is about 1E-9 that of steel (see Ten, Powers of); as a whole it is comparable to an all-pervading jelly, with almost perfect elasticity. The most complete vacuum is filled with ether. All this is a hypothesis, for the ether has never been proved to exist. Whether gravitation will ever be explained by It remains to be seen. [Transcriber's note: The Michelson-Morley experiment in 1887 (five years before this book) cast serious doubt on the ether. In 1905 Einstein explained electromagnetic phenomenon with photons. In 1963 Edward M. Purcell used special relativity to derive the existence of magnetism and radiation.]

    Y también en poemas....


    éter

    Hay un espacio entre una cosa,

    Inverosímil vacío,
    y otra.
    Un intermitente latido:
    Una luz que se enciende y se apaga,
    Un párpado que se abre y se cierra.
    Un corazón que se hincha y se contrae,
    La lucidez y el sueño.

    Hay kilómetros de distancia
    Entre una ciudad y otra,
    Un centenar de juicios para evitar al otro,
    Un lánguido momento para morir naciendo.

    Y casi nada, nada, algo, algo y algo.

    Falta ese espacio,
    Inverosímil vacío,
    Entre una cosa
    y la otra.

3-D View from the Front of Curiosity


This image is a 3-D view in front of NASA's Curiosity rover, which landed on Mars on Aug. 5 PDT (Aug. 6 EDT). The anaglyph was made from a stereo pair of Hazard-Avoidance Cameras on the front of the rover. The image is cropped but part of Mount Sharp, a peak that is about 3.4 miles (5.5 kilometers) high, is still visible rising above the terrain. 
This image was captured by the rover's front left Hazard-Avoidance camera at full resolution shortly after it landed. It has been linearized to remove the distorted appearance that results from its fisheye lens. A single "eye" view of Mount Sharp is available at PIA15986.

Head of Mast on Mars Rover Curiosity


This view of the head of the remote sensing mast on the Mars Science Laboratory mission's rover, Curiosity, shows seven of the 17 cameras on the rover. Two pairs of Navigation cameras (Navcams), among the rover's 12 engineering cameras, are the small circular apertures on either side of the head. On the top are the optics of the Chemistry and Camera (ChemCam) investigation, which includes a laser and a telescopic camera. The Mast Camera (MastCam) instrument includes a 100-millimeter-focal-length camera called MastCam-100 or M-100, and a 34-millimeter-focal-length camera called the MastCam-34 or M-34. The two cameras of the MastCam are both scientific and natural color imaging systems. The M-100 looks through a 1.2-inch (3-centimeter) baffle aperture, and the M-34 looks through a 2.1-inch (5.3-centimete) baffle aperture.
Malin Space Science Systems, San Diego, built MastCam and two other cameras on Curiosity. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington. 
CURIOSITY: NASA's Next Mars Rover



Seventeen Cameras on Curiosity

This graphic shows the locations of the cameras on NASA's Curiosity rover. The rover's mast features seven cameras: the Remote Micro Imager, part of the Chemistry and Camera suite; four black-and-white Navigation Cameras (two on the left and two on the right) and two color Mast Cameras (Mastcams). The left Mastcam has a 34-millimeter lens and the right Mastcam has a 100-millimeter lens. 

There is one camera on the end of a robotic arm that is stowed in this graphic; it is called the Mars Hand Lens Imager (MAHLI). 
There are nine cameras hard-mounted to the rover: two pairs of black-and-white Hazard Avoidance Cameras in the front, another two pair mounted to the rear of the rover, (dashed arrows in the graphic) and the color Mars Descent Imager (MARDI).

"Education elther functions as a instrument which is used to facilitate integration of the younger generation into the logic of the present system and bring about conformity or it becomes the practice of freedom, the means by wich men and woman deal critically and creatively with really and discover how to participate en the transfomation of their world"
Paulo Freire, Pedagogy of the Oppressed.


I agree with Paulo Freire. In my opinion education is very important to make a person CRITICAL and CREATIVE for the transformation in his world.
EDUCATION IS EVERYTHING!
