State of the Nation The full email: President Barack Obama said in Turkey : "We do not consider ourselves a Christian nation or a Jewish nation or a Muslim nation. We consider ourselves a nation of citizens who are bound by ideals and a set of values." (end of email) I've about had it. >From the treaty of Tripoli: Art. 11. (end my reply) Ok, maybe a bit terse. My aunt didn't. Here is her reply (and yes, she hit reply all...) I figured this would put you in an uproar, but to each his/her own opinion. As a friend of mine would say, Great Ooogly-Moogly! Do you think this was the last of it? I let this sit in my inbox for two full days before replying.

NASA Releases New High-Definition View of Iconic ‘Pillars of Creation’ Photo New view of the Pillars of Creation, visible light. NASA, ESA/Hubble and the Hubble Heritage Team. New view of the Pillars of Creation, visible light, detail. New view of the Pillars of Creation, infrared light. 2015 v. 1995 ‘Pillars of Creation’ comparison. One of the most iconic images ever produced by NASA is the “Pillars of Creation” photograph taken by Hubble Space Telescope in 1995. Now Hubble has revisited the famous pillars, capturing the multi-coloured glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust-coloured elephants’ trunks with the newer Wide Field Camera 3, installed in 2009. In addition, NASA says that although the original photograph was titled Pillars of Creation, the newer imagery suggests the columns might also contain a fair amount of destruction: Although the original image was dubbed the “Pillars of Creation”, this new image hints that they are also pillars of destruction.

How To Identify That Light In The Sky? What is that light in the sky? Perhaps one of humanity’s more common questions, an answer may result from a few quick observations. For example — is it moving or blinking? If so, and if you live near a city,the answer is typically an airplane, since planes are so numerous and so few stars and satellites are bright enough to be seen over the din of artificial city lights. If not, and if you live far from a city, that bright light is likely a planet such as Venus or Mars – the former of which is constrained to appear near the horizon just before dawn or after dusk.Sometimes the low apparent motion of a distant airplane near the horizon makes it hard to tell from a bright planet, but even this can usually be discerned by the plane’s motion over a few minutes.

How-To: Easily Remove the Vocals from Most Songs | 2015 Shortcut: When I wrote this article Audacity didn’t have an automatic center-panned vocal canceling effect… but now it does, so rather than do the stereo-separate / invert-one-track / play-both-as-mono trick (and that’s pretty much all there is to it), you should be able to find the Vocal Remover option in the Effects menu – but it’s more fun / interesting and can give better results if you do it yourself! =D I found this trick the other day whilst stumbling the Interwebs and thought I’d do a quick-write up w/ pictures to make it as easy as possible… For this exercise we’re going to be using a piece of free audio software called Audacity, which you can get for Linux, Windows and Mac. Update: If you’re trying this out on a Mac, please make sure you get Audacity 1.3 Beta or newer – the stable 1.2 version appears to have a missing equaliser decibal-range slider which you need towards the end of the process! 1.) Import Some Audio 2.) 3.) 4.) 5.) Wrap Up Cheers!

Citizens United v FEC - The Results A few months ago the United States Supreme Court made a terrible decision in a case called United Citizens v FEC. They basically decided that money was equivalent to speech in a political campaign, and that Congress couldn't limit the amount of money an organization could spend to support their chosen candidate(s). It doesn't take a lot of intelligence to know that this decision violated any remaining concepts of equality in political campaigns. LIBERAL Service Employees International Union..........$15,737,456 A.F.S.C.M.E...........$12,362,885 TOTAL..........$28,100,341 CONSERVATIVE U.S. Both of the liberal groups are unions. And anyone who thinks they are doing it because of political ideology or for the overall good of all Americans is just not very bright. Making matters even worse is the fact they are doing this in secret. There is no longer a fair and even playing field in American politics. Link to original post

As bright as a hundred million Suns: The clusters of monster stars that lit up the early universe -- ScienceDaily The first stars in the Universe were born several hundred million years after the Big Bang, ending a period known as the cosmological 'dark ages' -- when atoms of hydrogen and helium had formed, but nothing shone in visible light. Now two Canadian researchers have calculated what these objects were like: they find that the first stars could have clustered together in phenomenally bright groups, with periods when they were as luminous as 100 million Suns. Alexander DeSouza and Shantanu Basu, both of the University of Western Ontario in Canada, publish their results in a paper in Monthly Notices of the Royal Astronomical Society. The two scientists modelled how the luminosity of the stars would have changed as they formed from the gravitational collapse of disks of gas. The early evolution turns out to be chaotic, with clumps of material forming and spiralling into the centre of the disks, creating bursts of luminosity a hundred times brighter than average.

Physics and Astronomy Glossary Technical terms of science have very specific meanings. Standard dictionaries are not always the best source of useful and correct definitions of them. This glossary is not intended to be complete. This document is continually under development and may never be finished. Glossary Accurate. Absolute uncertainty. Compare: relative uncertainty. Action. Avogadro's constant. One must specify whether the value of Avogadro's constant is expressed for a gram-mole or a kilogram-mole. Though it seems inconsistent, the SI base unit is the gram-mole. Is Avogadro's constant just a number? , e, 3, 100, etc. The reciprocal of Avogadro's constant is numerically equal to the unified atomic mass unit, u, that is, 1/12 the mass of the carbon 12 atom. 1 u = 1.66043 x 10-27 kg = 1/6.02252 x 1023 mole-1.

Row Three ? Brave New Worldview ? 30 Science Fiction Films of the 21st Century A decade into the 21st Century and we have arrived at the future. The promise of Tomorrow. But instead we have looming energy crises, endless middle east conflict and more disappointing, we have no flying cars, Heck, for all the bright and clean future promised in 2001: A Space Odyssey, none of the real companies used as brands in the film even exist anymore. Even moving from the late 1960s to the mid 1980s, nobody makes DeLoreans (although they occasionally sell on Ebay), but cloning and tablet computing (as promised by Star Trek: The Next Generation) have more or less come to pass in this century. It is not the gizmos or the distopian aesthetics, that have brought Science Fiction into the new millennium, but the questions it asks of people or society in a future time or place and how they reflect on our own times. There have been a surprising number of excellent science fiction films to come about in the past decade that do this and do this well. The Fountain 28 Weeks Later The Host

Elgan: Big Business is watching you Computerworld - In the 1949 novel 1984, George Orwell imagined a brilliant but depressing future in which the government, a.k.a. "Big Brother," broadcast propaganda while simultaneously watching every citizen via ubiquitous "telescreens" in every home and in public places. Video feeds are monitored by the "Thought Police," who are constantly on the lookout for facial expressions and body language that reveal "thought crimes." They wanted to know what you were thinking. Aldous Huxley offered an alternative vision in 1932's Brave New World. Together, Orwell and Huxley predicted everything right, except three things. First, they got the timing wrong. Second, Orwell's telescreens served as an instrument of government propaganda and control. Third, the biggest error in both novels was the power of government. If you combine these two dystopian visions, set them in 2011 and put corporations in control, what do you get? Big Business is watching you Why this is a real trend
