Paradise Lost Epic poem by John Milton Composition[edit] In his introduction to the Penguin published edition of Paradise Lost, the Milton scholar John Leonard notes: "John Milton was nearly sixty when he published Paradise Lost in 1667. Leonard also notes that Milton "did not at first plan to write a biblical epic". Publication[edit] In the 1667 version of Paradise Lost, the poem was divided into ten books. Synopsis[edit] The poem follows the epic tradition of starting in medias res (lit. At several points in the poem, an Angelic War over Heaven is recounted from different perspectives. The story of Adam and Eve's temptation and fall is a fundamentally different, new kind of epic:[further explanation needed] a domestic one. Meanwhile, Satan returns triumphantly to Hell, amid the praise of his fellow fallen angels. Adam and Eve are cast out of Eden, and Michael says that Adam may find "a paradise within thee, happier far". Characters[edit] Satan[edit] Adam[edit] Adam is the first human created by God. C.
Nanotechnology Nanotechnology ("nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology[1][2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. Scientists currently debate the future implications of nanotechnology. Origins[edit] The concepts that seeded nanotechnology were first discussed in 1959 by renowned physicist Richard Feynman in his talk There's Plenty of Room at the Bottom, in which he described the possibility of synthesis via direct manipulation of atoms. Comparison of Nanomaterials Sizes Inspired by Feynman's concepts, K.

A good career move. Ultimately, you're hoping to communicate with extraterrestrials, colonize entire sets of star clusters, and eventually lord it over the entire Milky Way. You've got the motive, but what about the means? Well, forget about generation ships, suspended animation or ringworlds – the best way for you to explore, colonize and ultimately rule the Milky Way will be through the use of self-replicating robotic spacecraft – what are sometimes referred to as von Neumann probes. Von Neumann's idea Back in late 1940’s the brilliant mathematician John Von Neumann wondered if it might be possible to design a non-biological system that could replicate itself. The strength of Von Neumann's idea lies in the brute efficiency of exponential growth. In order to work, however, a von Neumann spacecraft would have to be put together using advanced nanotechnology and artificial intelligence -- technologies that we have yet to develop. 1. 1. 2. 3. 4. 5. 6.
Energy development Contemporary industrial societies use primary and secondary energy sources for transportation and the production of many manufactured goods. Also, large industrial populations have various generation and delivery services for energy distribution and end-user utilization.[note 4] This energy is used by people who can afford the cost to live under various climatic conditions through the use of heating, ventilation, and/or air conditioning. Level of use of external energy sources differs across societies, along with the convenience, levels of traffic congestion, pollution sources[10] and availability of domestic energy sources. Thousands of people in society are employed in the energy industry, of which subjectively influence and impact behaviors. Types of energy[edit] Open System Model (basics) Primary : They are found in nature: wind, water, solar,[note 12] wood, coal, oil, nuclear.Secondary : Are those obtained from primary energy sources: electricity, gas.

And as the Myers/Kurzweil conversation attests, there is little consensus on the best way for us to achieve human-equivalent AI. That said, I have noticed an increasing interest in the whole brain emulation (WBE) approach. While I believe that reverse engineering the human brain is the right approach, I admit that it's not going to be easy. But we have to start somewhere, and we have to start with a plan. Rules-based AI versus whole brain emulation Now, some computer theorists maintain that the rules-based approach to AI will get us there first. This approach aside, like Kurzweil, Bostrom, Sandberg and a growing number of other thinkers, I am drawn to the WBE camp. Emulation, simulation and cognitive functionalism Moreover, emulation is not simulation. The roadmap to whole brain emulation
Fusion power The Sun is a natural fusion reactor. Fusion power is the energy generated by nuclear fusion processes. In fusion reactions, two light atomic nuclei fuse to form a heavier nucleus (in contrast with fission power). In doing so they release a comparatively large amount of energy arising from the binding energy due to the strong nuclear force which is manifested as an increase in temperature of the reactants. Background[edit] Binding energy for different atoms. Mechanism[edit] Fusion happens when two (or more) nuclei come close enough for the strong nuclear force to exceed the electrostatic force and pull them together. Theoretically, any atom could be fused, if enough pressure and temperature was applied.[2] Mankind has studied many high energy fusion reactions, using particles beams.[3] These are fired at a target. Cross Section[edit] The fusion reaction rate increases rapidly with temperature until it maximizes and then gradually drops off. where: Lawson criterion[edit] Energy capture[edit]

And why wouldn't we want to? By enveloping the sun with a massive array of solar panels, humanity would graduate to a Type 2 Kardashev civilization capable of utilizing nearly 100% of the sun's energy output. Implausible you say? Think again: We are closer to being able to build a Dyson Sphere than we think. Now, before I tell you how we could do such a thing, it's worth doing a quick review of what is meant by a "Dyson sphere". Dyson Spheres, Swarms, and Bubbles The Dyson sphere, also referred to as a Dyson shell, is the brainchild of the physicist and astronomer Freeman Dyson. Needless to say, the amount of energy that could be extracted in this way is mind-boggling. I should note at this point that a Dyson sphere may not be what you think it is. Dyson's original proposal simply assumed there would be enough solar collectors around the sun to absorb the starlight, not that they would form a continuous shell. Megascale construction Why Mercury first?
Antimatter In particle physics, antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but have opposite charge and other particle properties such as lepton and baryon number. Encounters between particles and antiparticles lead to the annihilation of both, giving rise to varying proportions of high-energy photons (gamma rays), neutrinos, and lower-mass particle–antiparticle pairs. Setting aside the mass of any product neutrinos, which represent released energy which generally continues to be unavailable, the end result of annihilation is a release of energy available to do work, proportional to the total matter and antimatter mass, in accord with the mass-energy equivalence equation, E=mc2.[1] Antiparticles bind with each other to form antimatter just as ordinary particles bind to form normal matter. Antimatter in the form of anti-atoms is one of the most difficult materials to produce. History of the concept Notation Origin and asymmetry Positrons
Cyborg R.A.T. 9 Wireless Gaming Mouse for PC and Mac: Electronics Alan Turing Alan Mathison Turing, OBE, FRS (/ˈtjʊərɪŋ/ TEWR-ing; 23 June 1912 – 7 June 1954) was a British mathematician, logician, cryptanalyst, philosopher, pioneering computer scientist, mathematical biologist, and marathon and ultra distance runner. He was highly influential in the development of computer science, providing a formalisation of the concepts of "algorithm" and "computation" with the Turing machine, which can be considered a model of a general purpose computer.[2][3][4] Turing is widely considered to be the father of theoretical computer science and artificial intelligence.[5] During World War II, Turing worked for the Government Code and Cypher School (GC&CS) at Bletchley Park, Britain's codebreaking centre. For a time he led Hut 8, the section responsible for German naval cryptanalysis. After the war, he worked at the National Physical Laboratory, where he designed the ACE, among the first designs for a stored-program computer. Early life and career[edit] Cryptanalysis[edit]
