Technology studies

Technology society and life or technology and culture refers to dependency co-dependence, co-influence, and co-production of technology and society upon the other. This synergistic relationship occurred from the dawn of humankind, with the invention of simple tools and continues into modern technologies such as the printing press and computers. The academic discipline studying the impacts of science, technology, and society, and vice versa is called science and technology studies.

                                               

Across the Universe (message)

Across the Universe is an interstellar radio message consisting of the song "Across the Universe" by The Beatles that was transmitted on 4 February 2008, at 00:00 UTC by NASA in the direction of the star Polaris. This transmission was made using a 70-meter dish in the Deep Space Networks Madrid Deep Space Communication Complex, located in Robledo, near Madrid, Spain. This action was done in order to celebrate the 40th anniversary of the songs recording, the 45th anniversary of the DSN, and the 50th anniversary of NASA. The idea was hatched by Beatles historian Martin Lewis, who encouraged all Beatles fans to play the track as it was beamed to the distant star. The event marked the second time a song had ever been intentionally transmitted into deep space the first being Russias Teen Age Message in 2001, and was approved by Paul McCartney, Yoko Ono, and Apple Records. This IRM project has some significant defects in that the message was aimed at Polaris, which is 431 light years distant from us and whose planetary system, even if it exists, may not be suited for life, because it is a supergiant star, spectral type F7Ib. In addition, the transmission rate was very high, about 128 kbit/s, for such moderate transmitter power about 18 kW.

                                               

Active SETI

Active SETI is the attempt to send messages to intelligent extraterrestrial life. Active SETI messages are usually sent in the form of radio signals. Physical messages like that of the Pioneer plaque may also be considered an active SETI message. Active SETI is also known as METI. The term METI was coined by Russian scientist Alexander Zaitsev, who denoted the clear-cut distinction between Active SETI and METI: In 2010, Douglas A. Vakoch of the SETI Institute addressed concerns about the validity of Active SETI alone as an experimental science by proposing the integration of Active SETI and Passive SETI programs to engage in a clearly articulated, ongoing, and evolving set of experiments to test various versions of the Zoo Hypothesis, including specific dates at which a first response to messages sent to particular stars could be expected. On 13 February 2015, scientists at an annual meeting of the American Association for the Advancement of Science, discussed Active SETI and whether transmitting a message to possible intelligent extraterrestrials in the Cosmos was a good idea; That same week, a statement was released, signed by many in the SETI community including Berkeley SETI Research Center director Andrew Siemion, advocating that a "worldwide scientific, political and humanitarian discussion must occur before any message is sent". On 28 March 2015, an essay with a different point of view was written by Seth Shostak and published in The New York Times.

Alphagov

Alphagov was the project name of the experimental prototype website built by the Government Digital Service and launched on 11 May 2011 by the UK Cabinet Office that was open for public comment for two months in order to judge the feasibility of a single domain for British Government web services.
