One of the most talked about things this week was a strange video of a man who appeared to have a real life jet-powered hoverboard. The video was published by Zapata Racing, which has made water-powered versions of these flying machines for a few years now . The difference is that those are always tethered to some kind of personal watercraft. This new "Flyboard Air," as CEO Franky Zapata calls it, is something totally different. The video went viral on Monday, and it polarized the internet. People thought it was either the coolest thing ever invented , or that it was a massive hoax . Even optimistic parties, like myself, were skeptical . Maybe we all still feel a little burned by Tony Hawk and FunnyorDie, or maybe we were just being careful — after all, the video was suspiciously edited, there were very few details, and it just looked a little fake. Over the week, more videos of the flight(s) surfaced, and it appeared to be the real deal. This morning, thou...
Galileo Galilei (Italian: [ɡaliˈlɛːo ɡaliˈlɛi]; 15 February 1564[3] – 8 January 1642) was anItalian polymath: astronomer, physicist,engineer, philosopher, and mathematician.
He played a major role in the scientific revolution of the seventeenth century. His contributions to observational astronomy include the telescopic confirmation of thephases of Venus, the discovery of the four largest satellites of Jupiter (named theGalilean moons in his honour), and the observation and analysis of sunspots. Galileo also worked in applied science and technology, inventing an improved military compass and other instruments.
Galileo's championing of heliocentrism andCopernicanism was controversial during his lifetime, when most subscribed to eithergeocentrism or the Tychonic system.[4] He met with opposition from astronomers, who doubted heliocentrism because of the absence of an observed stellar parallax.[4] The matter was investigated by the Roman Inquisition in 1615, which concluded that heliocentrism was "foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture."[4][5][6] Galileo later defended his views in Dialogue Concerning the Two Chief World Systems, which appeared to attack Pope Urban VIII and thus alienated him and the Jesuits, who had both supported Galileo up until this point.[4] He was tried by the Inquisition, found "vehemently suspect of heresy", and forced to recant. He spent the rest of his life under house arrest.[7][8] While under house arrest, he wrote one of his best-known works, Two New Sciences, in which he summarized work he had done some forty years earlier on the two sciences now called kinematics and strength of materials.[9][10]
He has been called the "father ofobservational astronomy",[11] the "father of modern physics",[12][13] the "father of scientific method",[14] and the "father of science".
