Extraterrestrial life
The official U.S. government position on extraterrestrial life and the three major efforts to search for it. Clockwise from top left: The development and testing of hypotheses on extraterrestrial life is known as "exobiology" or "astrobiology", although astrobiology also considers Earth-based life in its astronomical context. Many scientists consider extraterrestrial life plausible, but there is no direct evidence of its existence.[2] Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial life, from radios used to detect possible extraterrestrial signals, to telescopes used to search for potentially habitable extrasolar planets.[3] It has also played a major role in works of science fiction. Science fiction works, especially Hollywood's involvement, has increased over the years the public's interest in the possibility of extraterrestrial life. §Background §Possible basis §Biochemistry All life on Earth is based upon 26 chemical elements.

Out Of This World: The Mysterious Mental Side Effects Of Traveling Into Space At first they thought it was asthma. The fighter squadron's 37-year-old commander suddenly started refusing to fly at high altitudes because of mysterious breathing problems. He also struggled to control feelings of wrath toward his coworkers, and that made him hyperventilate. It was only later that the commander would tell a Navy psychologist what really triggered him: That while flying at the edge of the troposphere, “a frightening feeling of detachment” set in. How Artificial Superintelligence Will Give Birth To Itself Kinja is in read-only mode. We are working to restore service. "So if you create an AI that has a terminal value of friendliness to humanity, the AI would not want to change itself in a way that caused it to be unfriendly to humanity," he says. "This way as the AI got smarter, it would use its enhanced intelligence to increase the odds that it did not change itself in a manner that harms us." "From there, the AGI would be interested in pursuing whatever goals it was programmed with — such as research, exploration, or finance." I think this is a mistake.

Nick Bostrom’s Superintelligence and the metaphorical AI time bomb Frank Knight was an idiosyncratic economist who formalized a distinction between risk and uncertainty in his 1921 book Risk, Uncertainty, and Profit. As Knight saw it, an ever-changing world brings new opportunities, but also means we have imperfect knowledge of future events. According to Knight, risk applies to situations where we do not know the outcome of a given situation, but can accurately measure the odds. Uncertainty, on the other hand, applies to situations where we cannot know all the information we need in order to set accurate odds in the first place.

Learn to Fight Capitalism at the School of Disobedience Jani Leinonen, “School of Disobedience” (2015) (courtesy the artist) A forthcoming exhibition in Helsinki will offer visitors an education grounded in disobedience and protest, equipping them with tools and ideas to challenge society’s injustices and fight for change. The School of Disobedience, which opens on September 4 at Finland’s contemporary art museum, Kiasma, is part art show, part educational institution: visitors to the museum are treated as students, receiving lessons from the more than 100 works on view or through a series of workshops with curricula that encourage civil disobedience through different media. Conceived by Finnish artist Jani Leinonen, whose own work is very critical of capitalist systems, the school intends to instill in the public — particularly young people — an urgent desire for social justice.
