67° giorno della memoria

18 GEN 2012 - I giovani sono ilfuturo del Paese. Ma non solo. Sono anche custodi della memoria.
''Diventeranno ambasciatori presso le loro famiglie, i lorocompagni e amici di questo orrore'', ha detto il ministrodell'Istruzione, Francesco Profumo, riferendosi agli studenti
-130 arrivati da tutta Italia - che assieme a lui hanno visitato oggi i campi di sterminio di Birkenau e Auschwitz. E' il primo viaggio all'estero per l'ex rettore del Politecnico di Torino da quando e' diventato titolare deldicastero di viale Trastevere e coincide con il ritorno adAuschwitz di un ministro dell'Istruzione: l'ultimo a visitarlo e' stato, infatti, Giuseppe Fioroni nel 2007.[...]
Olocausto ("bruciato interamente") è una parola derivante dal greco ὁλόκαυστος [1]. Essa definisce una tipologia di sacrificio [1], nel quale ciò che si sacrifica viene completamente arso. [...]
Per antonomasia dalla seconda metà del XX secolo "l'Olocausto" è divenuto il termine con il quale ci si riferisce al genocidio (circa sei milioni di vittime) compiuto dal Terzo Reich e dai suoi alleati a danno degli ebrei.[1]
Talvolta il termine viene riferito per estensione a tutte quelle persone, gruppi etnici e religiosi ritenuti "indesiderabili" dalla dottrina nazistaomosessuali, oppositori politici, RomSintizingaritestimoni di Geovapentecostalimalati di menteportatori di handicapprigionieri di guerra sovietici etc.[5]

International Holocaust Remembrance Day, 27 January, is an international memorial day for the victims of the Holocaust, the genocide that resulted in the annihilation of 6 million European Jews, 2 million Gypsies (Roma and Sinti), 15,000 homosexual people and millions of others by the Nazi regime. It was designated by the United Nations General Assembly Resolution 60/7 on 1 November 2005 during the 42nd plenary session.[1] The resolution came after a special session was held earlier that year on 24 January 2005 during which the United Nations General Assemblymarked the 60th anniversary of the liberation of the Nazi concentration camps and the end of the Holocaust.[2]

U. S., European High School Students Win Space Station Robotics Competition

U. S.and European high school student teams prevailed in a competition this week aboard the International Space Station involving a trio of colorful robotic spheres involved in the simulated exploration of an asteroid.
In all, 36 teams competed in the third annual Zero Robotics SPHERES challenge, which was orchestrated by the Massachusetts Institute of Technology, NASA and the U. S. Defense Advanced Research Projects Agency to provide students with an out-of-this-world example of the significance of math, science and engineering.
During the competition, NASA astronauts aboard the space station used laptops to control the flight of flying spheres using computer software developed by the teen aged competitors. The spheres move around using pulses of compressed gas.

The winningU. was Alliance Rocket, a partnership between Team Rocket, River Hill High School, Clarksville, Md.; Storming Robots, Branchburg, N.J.; and SPHEREZ of Influence, Rockledge High School, of Brevard County, Fla., NASA announced.
The winning European team was also a collaboration called Alliance CyberAvo. The partnership consisted of CyberAvo, I.T.I.S. Amedeo Avogrado, Turin, Italy; Ultima, Kaethe Kollwitz Oberschule, Berlin, Germany; and Lazy, Heinrich Hertz Gymnasium, Berlin, Germany, according to the European Space Agency.
This year marked the first time the SPHERES competition was extended beyong the U. S.
Student teams wrote programming code for two of the MIT developed robotic satellites. Astronauts Don Pettit, of NASA, and Andre Kuipers, of the European Space Agency, who currently live aboard the International Space Station, presided over the event in the station’s Japanese science module, Kibo.
This year’s competition involved a simulation in which minerals were extracted from asteroids, using the free floating sheres. The small satellites were permitted to collect tools, if needed, before they started to mine one of two virtual asteroids.
The robots moved using small jets. There were required to perform maneuvres based on realistic situations, such as docking, formation flying or retrieving objects.
Strategy was an important element of the competition. Teams could hinder their opponents or cooperate to share more points overall.
“It is just amazing to me what these high school students have accomplished,” said NASA Administrator Charles Bolden in a statement. “To program a robotic spacecraft with the precision of a NASA flight controller is quite a feat, but to have that ability, talent and discipline at such a young age is remarkable. Our future is in good hands.”
“Robots do have a soul, and their soul is your imagination, your future,” Stefano Suraniti, the Minister of Education for the Piedmont region inItaly, told the European competitors.

On Monday, high school students from across the country assembled in a lecture hall at MIT, patiently awaiting a call from NASA.

For four months, these students worked in teams as part of MIT’s Zero Robotics Challenge, a competition in which high school students program small robots to fly aboard the International Space Station (ISS). The robots, named SPHERES, were originally conceived and built by students in MIT’s Space Systems Laboratory.

These robots — roughly the size and shape of a basketball — run on compressed gas, and can be programmed to spin, revolve, hover and navigate through the air. In 2006, astronauts brought several of them aboard the ISS; a few years later, astronaut Greg Chamitoff PhD ’92 helped launch the Zero Robotics Challenge, making the robots accessible to high school students.

Chamitoff was on hand Monday, along with several colleagues who served as mentors during the challenge: former astronauts Leland Melvin, John Grunsfeld ’80 and Jeff Hoffman, now a professor of aeronautics and astronautics at MIT.

For this year’s challenge, students were given a “mission” to program robots to look for, mine and return alternative energy from fictitious asteroids in deep space. They were given coordinates for virtual asteroids located within the ISS and then had to develop computer codes to make a robot perform using various strategies, each of which earned a certain number of points.

For the past few months, student teams have been testing their codes in computer simulations, maneuvering virtual robots and competing against other teams in online games. The finalists — 38 teams with the best simulation scores — assembled at MIT on Monday for a chance to watch their codes play out in real robots on the ISS, 250 miles above Earth.

The students gathered in MIT’s 10-250 lecture hall. Many sported uniforms, including one team clad in NASA’s “pumpkin suit” orange. Once NASA successfully connected MIT with the ISS, a large screen at the front of the hall projected a live view from inside the station — and 10-250 erupted in cheers. Astronaut Don Pettit, onboard the ISS, responded, “We hear you loud and clear, MIT.”

Pettit and his colleague Andre Kuipers served as referees during the game, monitoring the robots, keeping score and occasionally pausing the game to refuel: Several times, the robots literally ran out of gas, and the astronauts rummaged through the ISS module’s storage bins for extra tanks of carbon dioxide.

Despite a few glitches in the video feed, most teams were able to watch their algorithms in action. During each match, both a red and a blue SPHERE began their missions simultaneously, slowly circling each other and moving about the module according to their preprogrammed trajectories.

“The coolest thing is not just that they’re controlling these robots onboard the ISS,” Melvin said. “In the future they may be developing algorithms to do inspections on the outside of the space station, or they may program robots to help vehicles dock. These are some really good skills that will help us down the road with NASA’s future missions.”

During the championship round, the video connection blinked out, leaving only a live audio feed. The astronauts continued running the final teams’ codes, and Pettit offered to narrate each round. 

“They’re stabilizing at 50 centimeters and closing,” Pettit reported to the earthbound crowd. “Are they going to crash? They just missed each other! It looks like they’ve completed … and we have a score!”

The winning team — dubbed “Team Rocket” — comprised representatives of three high schools in Maryland, New Jersey and Florida. The team’s mentor, astronaut John Grunsfeld, said the win was a surprise for the students, many of whom had never worked with this particular programming language before this challenge. 

“This is just fantastic to see all the students from all the schools and how well they did,” Grunsfeld said. “Hopefully some of them will come to MIT.”
