Physics and Astronomy Online Portal “The Readiness is all”: | Literature of War STC September 22, 2008 by rivese09 “If it be / now, ‘tis not to come; if it be not to come, it will be / now; if it be not now, yet it will come. The / readiness is all.” (Hamlet, V ii, 234-237) Hamlet’s primary inner conflict throughout the play is based around his inability to accept his unfortunate situation, and his struggle with himself to act firmly and resolutely to resolve it. His conversation with Horatio clearly demonstrates Hamlet’s new thinking. Though this may seem to be a depressing comment considering Hamlet’s circumstances, it rather should be taken as an encouraging sign that Hamlet is willing to face his destiny that he knew he would have to accept all along. These lines carry several important meanings to all its readers beyond the play, though obviously not in the same context as they do within Hamlet. If you interpret these lines from Hamlet in a broader context however, they take on a deeper meaning for Hamlet and for the reader. Like this: Like Loading...
Lattice points visible from the origin « The Lumber Room [A test of LaTeX-to-Wordpress conversion. Bugs remain, point them out. Original PDF] Here is a problem I love. [The solution is not mine. Question. Let us first imagine that we are standing at the origin, and that the grid is that of the lattice (integer) points. The blue points are visible; the grey points are not We now want to examine the question of which pairs are visible from the origin. not visible? is not visible because the point is "in the way", and the point obscures it. is not visible precisely when there is another lattice point blocking it, which is when there is an integer pair such that . is not visible precisely when there is an integer dividing both and , and is visible when there is no such integer, i.e. when have no common factor. For two "random" integers and , what is the probability that they have no common factor? For this to happen, it must be the case that no prime number divides both . , the probability that is divisible by is , and the same for , and so the probability that .
Detailed logarithmic timeline This timeline shows the whole history of the universe, the Earth, and humanity in one table. Each row is defined in years ago, that is, years before the present date, with the earliest times at the top of the chart. In each table cell on the right, references to events or notable people are given, more or less in chronological order within the cell. Each row corresponds to a change in log(time before present) of about 0.1 (using log base 10), similar to Renard numbers. A logarithmic timeline can also be devised for events which should occur in the future, barring unforeseen circumstances and assuming that we can extrapolate into the future based on our science.

Planets From Hell - How the Universe Works Documentary | HD 720p [Link]: KIC 8462852, aka WTF star, "the most mysterious star in our galaxy", ETI candidate, etc. - Less Wrong Discussion KIC 8462852, or the WTF (Where's the Flux?) star, is an F-type main sequence star about 1,480 ly away. It's a little larger and more massive than the sun, and a few times brighter. Kepler observations over the last few years reveal very strange large and aperiodic flux variations (up to 20%) - of the general form predicted by some ETI megastructure models. The star's fluctuations were discovered by the PlanetHunters team. Abstract of the WTF paper: Over the duration of the Kepler mission, KIC 8462852 was observed to undergo irregularly shaped, aperiodic dips in flux down to below the 20% level. From "Comets or Aliens?" In a another recent paper Jason Wright et al discusses the WTF star in more detail and critiques the comet theory. The Search for Extraterrestial Civilizations with Large Energy Supplies. Arnold (2005), Forgan (2013), and Korpela et al. (2015) noted that planet-sized artificial structures could be discovered with Kepler as they transit their host star.
The Purpose of Higher Thinking | Literature of War STC September 21, 2008 by bergd09 Hamlet: Sure He that made us with such large discourse, / Looking before and after, gave us not / That capability and godlike reason / To fust in us unused. (Act 4:4, lines 38-41) William Shakespeare poses some of the most thought provoking questions on the meaning of life throughout Hamlet. As a young man, Hamlet faces many of the same questions youths still face today. Similar to Hamlet, I often wonder why humans were given the ability of complex thinking. Throughout the play, Hamlet contemplates the meaning of life. One of the greatest reasons why Shakespeare is so easy to relate to is because of the universal questions he asks in his plays.

Kardashev scale The Kardashev scale is a method of measuring a civilization's level of technological advancement, based on the amount of energy a civilization is able to utilize. The scale has three designated categories called Type I, II, and III. A Type I civilization uses only resources available on its home planet, Type II harnesses all needed energy from its local star, and Type III of its galaxy. The scale is only hypothetical, but it puts energy consumption in a cosmic perspective. It was first proposed in 1964 by the Soviet astronomer Nikolai Kardashev. Various extensions of the scale have been proposed since, from a wider range of power levels (types 0, IV and V) to the use of metrics other than pure power. Definition Type I "Technological level close to the level presently attained on earth, with energy consumption at ≈4×1019 erg/sec (4 × 1012 watts) Type II Type III "A civilization in possession of energy on the scale of its own galaxy, with energy consumption at ≈4×1044 erg/sec
Into The Universe With Stephen Hawking: Aliens Astronomers spy most distant Solar System object ever NASA/ESA/G. Bacon/STScI The Kuiper belt lies beyond Neptune. Astronomers have spotted the most distant object ever seen in the Solar System: a frigid world that currently lies 103 times farther from the Sun than Earth does. It breaks a record previously held by the dwarf planet Eris, which had been seen at 97 times the Earth–Sun distance. Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington DC, reported the object on 10 November at the American Astronomical Society’s Division for Planetary Sciences meeting in National Harbor, Maryland. The object sits beyond the edge of the Kuiper belt (home to Eris and Pluto), and into the inner fringes of the next part of the Solar System, the Oort cloud. But astronomers have not tracked the newfound object for long enough to know its full path, and there is a chance that it will travel much closer to the Sun than its current distance of 103 astronomical units (au; 1 au is approximately 150 million kilometres).
Characteristics of a Shakespearean Tragic Hero (From Aristotle) | Online Homework Help | SchoolWorkHelper He must be a person of some stature or high position such as a king, general, or a nobleman.He must be a good person. He must matter to us and we must see him as a worthwhile person. Because of his position, his actions usually have far reaching effects.He must possess a character trait or quality which under normal circumstances would be a virtue, but under the special circumstances of the play proves to be a fatal flaw (hamartia- the tragic flaw that leads to his downfall).He usually makes further errors in judgment following his misdeed.Often he has a distorted perception of, or is blind to, reality.He suffers both outwardly (isolation, alienation, attacks) and inwardly (tortured conscience).He must elicit both pity and fear from the audience (catharsis).Usually, he recognizes his mistakes in the end.He must die Citation St.
Technological singularity The technological singularity (also, simply, the singularity) is the hypothesis that the invention of artificial superintelligence (ASI) will abruptly trigger runaway technological growth, resulting in unfathomable changes to human civilization. According to this hypothesis, an upgradable intelligent agent (such as a computer running software-based artificial general intelligence) would enter a "runaway reaction" of self-improvement cycles, with each new and more intelligent generation appearing more and more rapidly, causing an intelligence explosion and resulting in a powerful superintelligence that would, qualitatively, far surpass all human intelligence. Four polls, conducted in 2012 and 2013, suggested that the median estimate was a 50% chance that artificial general intelligence (AGI) would be developed by 2040–2050. Background Intelligence explosion The intelligence explosion is a possible outcome of humanity building artificial general intelligence (AGI).
The Universe - How Big, How far, How fast - Documentary | HD 720p Cosmos is a fantastic show about ideological conversion more than it’s about science Like Carl Sagan before him, Neil deGrasse Tyson is constructing a cult of personality. Also like Sagan, that personality is not his own. In both its versions, Cosmos has had to serve a number of masters — they’ve both had to educate, to entertain, and to bring in advertising. By far their most defining goal, however, the one that most differentiates them from both the Planet Earths and Bill Nyes of the world, is ideological. In many scientifically inclined circles, that’s a borderline offensive accusation, and the nervousness has only become more acute since Sagan’s day. Who couldn’t love that face? Both Sagan’s Cosmos and Tyson’s are explicit and unmoving on the issue of faith: belief without evidence is the antithesis of reason, and irreconcilable with a scientific understanding of the universe. Neither ever tries to sugar-coat its view of the facts or their implications, because ultimately the views and implications are the point, rather than the facts themselves.
