Abusing The Kardashev Scale For Fun And Profit How advanced are you? "Your race hasn't even reached Type 1 on the Kardashev scale. It doesn't control the resources of this one planet, let alone a solar system or a galaxy. The Time Lords were the Type 4 civilization. We had no equals. The idea of Technology Levels has some actual reference in the real world in the form of the Kardashev Scale , which indicates how much power a civilization uses. rather than the specific values of celestial objects. Unmarked Spoilers Abound From This Point Onward open/close all folders Type 0: Less than Type I. The human civilization on Earth is currently hovering around a 0.72, with a power level of about 1.6 x 1013 W, the vast majority extracted from high-density chemically stored solar energy (fossil fuels), with some nuclear fission on the side and other direct and indirect solar energy harvesting methods contributing a small fraction. Borderline Type I: Power use roughly equivalent to a terrestrial planet's insolation. 1 E 16 W
Mathematicians Predict the Future With Data From the Past | Wired Enterprise Peter Turchin. Image: Peter Turchin. In Isaac Asimov’s classic science fiction saga Foundation, mathematics professor Hari Seldon predicts the future using what he calls psychohistory. Drawing on mathematical models that describe what happened in the past, he anticipates what will happen next, including the fall of the Galactic Empire. That may seem like fanciful stuff. Turchin — a professor at the University of Connecticut — is the driving force behind a field called “cliodynamics,” where scientists and mathematicians analyze history in the hopes of finding patterns they can then use to predict the future. These academics have the same goals as other historians — “We start with questions that historians have asked for all of history,” Turchin says. ‘We start with questions that historians have asked for all of history. — Peter Turchin Turchin didn’t begin as a historian. He founded the movement in the late ’90s, and since then, many more have joined in. The basic idea is nothing new.
Fermi paradox A graphical representation of the Arecibo message – Humanity's first attempt to use radio waves to actively communicate its existence to alien civilizations The Fermi paradox (or Fermi's paradox) is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilization and humanity's lack of contact with, or evidence for, such civilizations.[1] The basic points of the argument, made by physicists Enrico Fermi and Michael H. Hart, are: The Sun is a young star. According to this line of thinking, the Earth should already have been colonized, or at least visited. Overview[edit] The age of the universe and its vast number of stars suggest that unless the Earth is very atypical, extraterrestrial life should be common.[4] In an informal discussion in 1950, the physicist Enrico Fermi questioned why, if a multitude of advanced extraterrestrial civilizations exists in the Milky Way galaxy, evidence such as spacecraft or probes is not seen. Name[edit]
Kardashev civilizations A scheme for classifying advanced technological civilizations proposed by Nikolai Kardashev1 in 1964. He identified three possible types and distinguished between them in terms of the power they could muster for the purposes of interstellar communications. A Type I civilization would be able to marshal energy resources for communications on a planet-wide scale, equivalent to the entire present power consumption of the human race, or about 1016 watts. A Type II civilization would surpass this by a factor of approximately ten billion, making available 1026 watts, by exploiting the total energy output of its central star. Carl Sagan pointed out that the energy gaps between Kardashev's three types were so enormous that a finer gradation was needed to make the scheme more useful. Karadashev civilizations and SETI Kardashev explored the consequences of a Type II or III civilization diverting all of its non-essential power resources into an effort to communicate with other races.

TIME TRAVEL MULTIVERSE DOCUMENTARY Enrico Fermi Enrico Fermi (Italian: [enˈri.ko ˈfeɾ.mi]; 29 September 1901 – 28 November 1954) was an Italian physicist, best known for his work on Chicago Pile-1 (the first nuclear reactor), and for his contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics. He is one of the men referred to as the "father of the atomic bomb".[4] Fermi held several patents related to the use of nuclear power, and was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and the discovery of transuranic elements. He was widely regarded as one of the very few physicists to excel both theoretically and experimentally. Fermi's first major contribution was to statistical mechanics. Fermi left Italy in 1938 to escape new Italian Racial Laws that affected his Jewish wife Laura. Early life[edit] Enrico Fermi was born in Rome on 29 September 1901.

How Do I Answer When I’m Stumped by an Important Question? Dear Lifehacker,I have an important presentation coming up, and although I feel very prepared, I’m afraid during the Q&A someone will ask me a question I won’t be able to answer. What’s the best way to respond when I get caught stumped?Signed,Nervous Speaker Dear Nervous,I think we’ve all been there at some point, whether it’s during a presentation, interview, or even just a political debate with friends. Here are a few tips to calmly address tough questions when you don’t know the answer (and avoid looking like a deer caught in headlights). Stall/Think Through the Answer If the answer is just at the tip of your tongue, give yourself a few minutes to think about it. This strategy works if you have some background information to guide your answer or during interviews when the question is testing your ability to think through a problem, rather than find an exact answer. Ask for Assistance from the Audience If an audience member helps out, great. Love,Lifehacker
¿Cómo desarrolló EE.UU. la bomba nuclear? En su discurso, denominado 'Los recuerdos de la era nuclear: Los Álamos', Glauber, de 87 años de edad, compartió sus recuerdos sobre la serie de investigaciones científicas realizadas por EE.UU. durante la Segunda Guerra Mundial, conocidas bajo el nombre el Proyecto Manhattan. Cuando empezó a participar en el proyecto, era estudiante de Harvard y tenía 18 años, la edad en la que los jóvenes estadounidenses eran reclutados por el Ejército. En aquel entonces muchos de sus profesores ya se habían ido a trabajar para varios proyectos militares. Después de que rellenara el cuestionario y le llamaran, ni siquiera sabía dónde tendría que trabajar. Lo único que le dijeron los hombres "vestidos de negro" que se pusieron en contacto con él, era que tenía que coger un tren con destino a Chicago y llamar desde allí por teléfono a alguien que debía entregarle un billete a Santa Fe. "Me quedé conmocionado. Me quedé conmocionado.
John Smart (futurist) John M. Smart is a futurist and scholar of accelerating change . He is founder and president of the Acceleration Studies Foundation , an organization that does “outreach, education, research, and advocacy with respect to issues of accelerating change.”. [ 1 ] Smart has an MS in futures studies from the University of Houston , and a BS in business administration from U.C. Berkeley . Ideas [ edit ] Smart is the principal advocate of the concept of “STEM compression,” (formerly "MEST compression") the idea that the most (ostensibly) complex of the universe’s extant systems at any time (galaxies, stars, habitable planets, living systems, and now technological systems) use progressively less space, time, energy and matter (“STEM”) to create the next level of complexity in their evolutionary development. [ 2 ] A similar perspective is found in Buckminster Fuller ’s writings on ephemeralization . See also [ edit ] References [ edit ] External links [ edit ]
