The Revolution Will Be Tweeted - 1 views

  • Much of the organization and mobilization occurred through the Internet, particularly on social media such as Facebook and Twitter. But social media also played a vital role as a democratic model. Its inclusive space indirectly taught lessons in democracy to a wide sector of Egyptian youth that was not necessarily politically inclined. When the right moment arrived, they were ready to join the revolt.
  • What happened in January 2011 in Egypt did not start in January 2011. It began at least ten years earlier, and it’s not over yet
  • The main catalyst for the January 25 revolution was the Internet, so it may be accurate to describe this as an Internet-based revolution. Not that the Internet was the only factor involved, or that Internet users were the only ones protesting. But the Internet was the tool that showed every dissident voice in Egypt that he or she is not alone, and is indeed joined by at least hundreds of thousands who seek change.

  • Facebook did not go to Tahrir Square. The people did. Twitter did not go to Al-Qaied Ibrahim Square. The people did.
  • More than one-third of Egypt’s population of eighty million remains illiterate, and just 25 percent of Egyptians use the Internet. However, Facebook and Twitter were instrumental in organizing, motivating, and directing these crowds as to where to go and what to do. Egypt’s revolution was created as an event on Facebook eleven days in advance. People clicked “I’m attending.” Certainly, this was a people’s revolution, yet one based on and accelerated in many ways by the Internet. What happened in Tahrir and every square in Egypt was the accumulation of years and years of activism, including Internet activism. Social media prepared Egyptians for the revolution and enabled them to capitalize on an opportunity for change when the time came.
  • The Internet, by definition, is a democratic medium, at least in the sense that anyone with Internet access is a potential publisher of information.
  • The mere presence of the Internet as a source of information helps open up a freer space for public debate, and makes it much more difficult for governments to censor information.
  • Internet activism started in Egypt with the appearance of Web 2.0 technology in the country around 2003
  • Blogging was the first valuable brainchild of Web 2.0 technologies.
  • The phenomenon exploded in the Arab world, with Egyptian bloggers pioneering and leading the scene. Blogger numbers in the region approached half a million by the beginning of 2009, the great majority of them coming from Egypt.
  • Political blogging in particular became more popular, as users felt that they could remain anonymous if they so wished
  • Nevertheless, most Egyptian political bloggers choose to blog under their real names, which frequently got them in trouble with the regime. The state security crackdown on bloggers was testimony to their potential impact.
  • Undoubtedly, blogging created a space for the voiceless in Egypt.
  • It was the first time individuals felt they could make themselves heard. That in itself was important, whether or not the content was political, and whether or not anyone was reading the blogs. The phenomenon created a venting space for people who had long gone unheard.
  • Early on, Alaa Abdel Fattah and Manal Hassan were awarded the Special Award from Reporters Without Borders in the international Deutsche Welle’s 2005 Weblog Awards (Best of Blogs) contest, where their blog was cited as an instrumental information source for the country’s human rights and democratic reform movement. The husband-and-wife team had created one of Egypt’s earliest blogs, “Manal and Alaa’s Bit Bucket,” where they documented their off-line activism and posted credible information on protests and political movements, election monitoring and rigging, and police brutality.
  • Another award-winning blogger was Wael Abbas. He received several honors, including the 2007 Knight International Journalism Award of the International Center for Journalists for “raising the standards of media excellence” in his country. This was the first time that a blogger, rather than a traditional journalist, won the prestigious journalism award, a testament to the important work such bloggers were doing. In the same year, CNN named Abbas Middle East Person of the Year. He has been instrumental in bringing to light videos of police brutality in Egypt, a topic that was taboo before he and other bloggers ventured into it. As a result of these efforts, the Egyptian government at one point brought three police officers to justice on charges of police brutality for the first time in Egypt’s history; they were convicted and sentenced to three years in jail.
  • As blogging was becoming a phenomenon in Egypt, some political movements started having a strong on-line presence, and taking to the streets based on their on-line organization. The most important was probably the Kefaya movement, whose formal name is The Egyptian Movement for Change. The movement was established in 2004 by a coalition of political forces, and became better known by its Arabic slogan. The word kefaya is Arabic for ‘enough,’ and as the name implies, the movement called for an end to the decades-old Mubarak regime, and for guarantees that his son would not succeed him as president. Kefaya was instrumental in taking people to the streets, thus bridging the gap between the on-line and the off-line worlds. Many of its supporters were bloggers, and many of the street protesters started blogging. So, increasingly, reports on the demonstrations found their way into blogs and were provided media coverage even when the traditional media ignored them or were afraid to cover them. One result was that many more Egyptians gained the courage to write blogs that openly criticized the authoritarian system and crossed the ‘red line’ of challenging their president.
  • nternet applications such as the video-sharing platform YouTube, which appeared in 2005, took blogging to a higher level.
  • hey were also capable of videotaping street protests and uploading the clips on YouTube. Watching people chanting “Down with Hosni Mubarak” in the mid-2000s was a totally new, riveting experience, which led many other brave Egyptians to join these demonstrations. Internet activists and blogger stars such as Wael Abbas, Alaa Abdel Fattah, Manal Hassan, Hossam El-Hamalawy, Malek Mostafa, and others uploaded hundreds of videos of police brutality, election rigging, and different violations of human and civic rights.
  • media, the platforms that allow for wider user discussions and user-generated content such as MySpace, Facebook, and Twitter
  • he next important development came with the introduction of what is typically known as social
  • The structure of social media taught Egyptians that space exists that you can call your own, your space, where you can speak your mind. To many in the West, this is probably no big deal. There are countless venues where they can express their opinions relatively freely. But for people in Egypt, and in the Arab world in general, this was a new phenomenon, and one I believe to be of profound importance.
  • horizontal communication.’ Before social networks, Egyptian youth were accustomed to being talked at, rather than talked to or spoken with. Communication was mostly vertical, coming from the regime down to everyone else
  • Authoritarian patterns of communication do not allow for much horizontal interaction. But social networks do, and eventually their existence on the Internet taught Egyptian youths a few lessons in democratic communication, even if the essence of the conversations carried out was not necessarily political in nature.
  • The bulk of those that I believe were affected by these lessons in democratic expression were clusters of the population that were not previously politically oriented. These form a good sector of those who took to the streets on January 25, and were joined by millions who held their ground in Tahrir Square and in every square in Egypt until Mubarak was toppled. The majority of these millions, including myself, were people who had never participated in a demonstration before. They were not political activists before January 25, but they saw or heard the call for action, and it touched a nerve as they found safety in numbers
  • another function that social networks served: making you realize that you’re not alone.
  • Perhaps the first time Egyptians learned about the power of social networks was on April 6, 2008. Workers in the Egyptian city of Al-Mahalla Al-Kobra planned a demonstration to demand higher wages. Esraa Abdel Fattah, an activist then twenty eight years old, felt for the workers and wanted to help them. She formed a group on Facebook and called it ‘April 6 Strike’ to rally support for the workers.
  • he knew it was too much to ask people to join in the protest, so she simply asked them to participate in spirit by staying home that day, not going to work, and not engaging in any monetary transactions such as buying or selling. The group was brought to the attention of the traditional media and was featured on one of Egypt’s popular talk shows, thus getting more exposure. What ensued surpassed all expectations. To Abdel Fattah’s own surprise (and everyone else’s), the Facebook group immediately attracted some seventy three thousand members. Many of these, and others who got the message through traditional media, decided to stay home in solidarity with the workers. Others were encouraged to stay home by a bad sandstorm that swept across parts of Egypt that day, and yet others stayed home for fear of the strong police presence on the streets.
  • The overall outcome made political activists realize that social networks could be a vital tool in generating support for a political cause, and in encouraging people to join a call for action.
  • The April 6 event was meaningful because it provided a sense that people were actually willing to take an action, to do something beyond clicking a mouse
  • three months before the January 25 revolution, Malcolm Gladwell argued in a much-discussed article in The New Yorker under the title “Small Change: Why the revolution will not be tweeted” that social media can’t provide what social change has always required. He said that social media is good when you’re asking people for small-scale, low-risk action, but not for anything more. “Facebook activism succeeds,” he wrote, “not by motivating people to make a real sacrifice but by motivating them to do the things that people do when they are not motivated enough to make a real sacrifice.” He explained that this is because high-risk activism is a “strong-tie phenomenon,” meaning that those who carry out such acts of activism have to personally know each other well and develop strong personal ties before they would risk their lives for each other or for a common cause. Since Facebook and Twitter provide mostly “weak-tie” connections, since users typically have a strong off-line social tie with only a small percentage of their ‘friends’ or ‘followers,’ these social networks were therefore not capable of motivating people for a high-risk cause. He therefore concluded that a social network “makes it easier for activists to express themselves, and harder for that expression to have any impact.”
  • nowing that you are in the company of many who share your utter belief in the same cause. That is something that social networks delivered
  • ne of the Facebook pages that played a major role in this regard was the Khaled Said page. Khaled Said was a young Egyptian who was brutally beaten to death by police informants outside an Internet café in Alexandria in June 2010. He had an innocent face that everyone could identify with. He could be anyone, and anyone could’ve been him. The Facebook page “We Are All Khaled Said” appeared shortly thereafter. It started asking its members, whose numbers increased steadily, to go out on silent standing protests in black shirts with their back to the streets. The demonstrations started in Alexandria and soon spread to every governorate in Egypt. Numbers increased with every protest. More and more people gained a little more courage and tasted the freedom of dissent.
  • One of the main advantages of the Khaled Said page was how well organized the events were. Protesters were provided with exact times and locations, and given exact instructions on what to wear, what to do, as well as who to contact in the case of any problems with security forces.
  • t was the Khaled Said page that eventually posted the ‘event’ for a massive demonstration on January 25, Egypt’s Police Day.
  • The administrators usually polled their users, asking them to vote for their place or time of preference for the next protest. The responses would be in the thousands, sometimes tens of thousands, and the administrators would read them all, and give a breakdown, with exact numbers and percentages, of the votes.
  • The January 25 demonstration was motivated and aided by an important intervening variable, the revolt in Tunisia. When Tunisian protesters succeeded in ousting President Zine El-Abidine Ben Ali on January 14, Egyptians felt that toppling a dictator through demonstrations was finally possible.
  • he Khaled Said page, which by then had about six hundred thousand followers, demonstrated its strong ability to organize. They listed all the major squares in every Egyptian governorate where they expected people to gather, and again gave specific instructions on what to wear, what to take with you, and who to contact in times of trouble. They then alerted the users that the listed venues for demonstration would change at midnight on January 24 to give police forces a lesser chance of mobilizing against them the next day. On the morning of January 25, there were close to half a million people who had clicked “I’m attending” the revolution. Today, the Khaled Said page has more than 1.7 million users, by far more than any other Egyptian Facebook page.
  • nd indeed that was what happened. We witnessed another key moment illustrating the power of the interaction between social media, traditional media, and interpersonal communication. Newspapers, broadcasters, and on-line outlets had been discussing the potential ‘Facebook demonstration’ for a few days prior to January 25. As groups of demonstrators marched through the streets enroute to main squares chanting “Ya ahalina endamo lina,” (“Friends and family, come join us”), people watching from their balconies and windows heeded the calls and enabled the protests to snowball to unprecedented numbers. People were galvanized by the sight. The core activists, who attended every demonstration for years, were suddenly seeing new faces on January 25, mostly mobilized by the Internet. They came by the thousands, and then by the hundreds of thousands, numbers larger than anyone had expected.
  • Twitter played an important though slightly different role. Crucial messages relayed in short bursts of one hundred and forty characters or less made protesters ‘cut to the chase.’ Most activists tweeted events live rather than posting them on Facebook. Twitter was mainly used to let people know what was happening on the ground, and alert them to any potential danger. It usually was ahead of Facebook in such efforts. Twitter also enabled activists to keep an eye on each other. Some managed to tweet ‘arrested’ or ‘taken by police’ before their mobile phones were confiscated. Those words were incredibly important in determining what happened to them and in trying to help them. Most activists are, to this day, in the habit of tweeting their whereabouts constantly, even before they go to sleep, because they know that fellow activists worry if they disappear from the Twittersphere.
  • When the Egyptian regime belatedly realized on January 25 how dangerous social networks could be to its survival, the first thing it did was block Twitter. Internet censorship is a ridiculously ineffective strategy, though. Users were tech-savvy enough to find their way onto proxy servers within minutes, and to post on Facebook how to gain access to Twitter and how to remain on Facebook if the regime blocks it, which indeed happened later. The government felt it didn’t have any other option but to block all Internet access in the country for five days starting January 27 (as well as mobile telephone communications for one day). By then it was too late. People had already found their way to Tahrir and nearly every square in Egypt. Ironically, some were partly motivated by the Internet and communication blockage to take to the streets to find out what was happening and be part of it. And they were joined by workers’ movements in many governorates that expanded the protester numbers into the millions. The major squares of Egypt were full of people of every age, gender, religion, creed, and socio-economic status
  • Gladwell, it turned out, was wrong. These people didn’t know each other personally, but the “weak” personal ties had not proved a barrier to high-risk activism. Egyptians discovered the strong tie of belonging to the common cause of ousting a dictator
  • ocial network users were not the only ones revolting, and social networks were not the only reason or motivation for revolt. However, the role that social media have played over the years in indirectly preparing sectors of Egyptian youths for this moment, and in enabling them to capitalize on an opportunity for change when the time came, cannot be understated.  It can also be said that the role of social networks in Egypt has hardly ended. The revolution is not yet complete.

How the NSA's Domestic Spying Program Works | Electronic Frontier Foundation - 0 views

  • When the NSA’s spying program was first exposed by the New York Times in 2005, President Bush admitted to a small aspect of the program—what the administration labeled the “Terrorist Surveillance Program”—in which the NSA monitored, without warrants, the communications of between 500-1000 people inside the US with suspected connections to Al Qaeda.

      The first time the NSA's spying programs where first exposed and what was chosen to be revealed by the Bush administration.
  • But other aspects of the Program were aimed not just at targeted individuals, but perhaps millions of innocent Americans never suspected of a crime.
  • A person familiar with the matter told USA Today that the agency's goal was "to create a database of every call ever made" within the nation's borders. All of this was done without a warrant or any judicial oversight.

      The intelligence gathering power of the NSA.
  • First, the government convinced the major telecommunications companies in the US, including AT&T, MCI, and Sprint, to hand over the “call-detail records” of their customers. According to an investigation by USA Today, this included “customers' names, street addresses, and other personal information.” In addition, the government received “detailed records of calls they made—across town or across the country—to family members, co-workers, business contacts and others.”
    • abdulrahmanabdo
       
      How the intensive intelligence gathering began for the NSA.
  • It works like this: when you send an email or otherwise use the internet, the data travels from your computer, through telecommunication companies' wires and fiber optics networks, to your intended recipient. To intercept these communications, the government installed devices known as “fiber-optic splitters” in many of the main telecommunication junction points in the United States (like the AT&T facility in San Francisco). These splitters make exact copies of the data passing through them: then, one stream is directed to the government, while the other stream is directed to the intended recipients.

  • In April 2012, long-time national security author James Bamford reported NSA is spending $2 billion to construct a data center in a remote part of Utah to house the information it has been collecting for the past decade. “Flowing through its servers and routers and stored in near-bottomless databases,” Bamford wrote, “will be all forms of communication, including the complete contents of private emails, cell phone calls, and Google searches, as well as all sorts of personal data trails—parking receipts, travel itineraries, bookstore purchases, and other digital ‘pocket litter.’

Rømer's determination of the speed of light - Wikipedia, the free encyclopedia - 0 views

  • Order of magnitude[edit] Rømer starts with an order of magnitude demonstration that the speed of light must be so great that it takes much less than one second to travel a distance equal to Earth's diameter. The point L on the diagram represents the second quadrature of Jupiter, when the angle between Jupiter and the Sun (as seen from Earth) is 90°.[note 6] Rømer assumes that an observer could see an emergence of Io at the second quadrature (L), and also the emergence which occurs after one orbit of Io around Jupiter (when the Earth is taken to be at point K, the diagram not being to scale), that is 42½ hours later. During those 42½ hours, the Earth has moved further away from Jupiter by the distance LK: this, according to Rømer, is 210 times the Earth's diameter.[note 7] If light travelled at a speed of one Earth-diameter per second, it would take 3½ minutes to travel the distance LK. And if the period of Io's orbit around Jupiter were taken as the time difference between the emergence at L and the emergence at K, the value would be 3½ minutes longer than the true value. Rømer then applies the same logic to observations around the first quadrature (point G), when Earth is moving towards Jupiter. The time difference between an immersion seen from point F and the next immersion seen from point G should be 3½ minutes shorter than the true orbital period of Io. Hence, there should be a difference of about 7 minutes between the periods of Io measured at the first quadrature and those measured at the second quadrature. In practice, no difference is observed at all, from which Rømer concludes that the speed of light must be very much greater than one Earth-diameter per second.[5]
  • However Rømer also realised that any effect of the finite speed of light would add up over a long series of observations, and it is this cumulative effect that he announced to the Royal Academy of Sciences in Paris. The effect can be illustrated with Rømer's observations from spring 1672. Jupiter was in opposition on 2 March 1672: the first observations of emergences were on 7 March (at 07:58:25) and 14 March (at 09:52:30). Between the two observations, Io had completed four orbits of Jupiter, giving an orbital period of 42 hours 28 minutes 31¼ seconds. The last emergence observed in the series was on 29 April (at 10:30:06). By this time, Io had completed thirty orbits around Jupiter since 7 March: the apparent orbital period is 42 hours 29 minutes 3 seconds. The difference seems minute – 32 seconds – but it meant that the emergence on 29 April was occurring a quarter-hour after it would have been predicted. The only alternative explanation was that the observations on 7 and 14 March were wrong by two minutes.

Are Solar Sails the Future of Space Travel? - 0 views

    • Virinchi Tadikonda
       
      Innovation is one of the most important factors of space travel. This simple design can turn into something that we can use to potentially travel vast distances. 
  • But it took a long time for solar sails to go from concept to reality. The first successful demonstration of the propulsion system didn't come until 2010, when Japan's Ikaros probe deployed its 46-foot-wide (14 m) sail and became the first craft ever to cruise through space on the backs of photons.
    • Virinchi Tadikonda
       
      This just tells us that nothing comes easy, and that we might actually be a long distance away from achieving the next space milestone, which is setting foot on another planet. 
  • The $27 million Sunjammer mission, which takes its name from the Arthur C. Clarke story, will use a sail built by California-based company L'Garde that measures 124 feet (38 m) on a side. The sail, made of an advanced material called Kapton, is just 5 microns (about 0.0002 inches) thick. It weighs less than 70 pounds (32 kilograms) and packs down to the size of a dishwasher, NASA officials have said.
    • Virinchi Tadikonda
       
      As much as funds are being cut from NASA and budget cuts are taking a toll on all space related activities, research is definitely crucial. But we do not hear about these researches in the news.

      Prevention of disasters is one of the most important security aspects of technology. This kind of probes will enhance safety among the public but the one thing I see is that the media has not covered this. It is not a big aspect of technology it seems, and I disagree. 
  • And some researchers have even higher hopes for solar sails, suggesting that a truly enormous sail —one the size of Texas, for example — could send a spaceship to another star system in just a few centuries. (A space-based laser would have to shine a powerful beam on the sail as the craft moved farther and farther away from the sun, however.)   
    • Virinchi Tadikonda
       
      This is the definition of future research for the benefit of society in the generations to come. This kind of technology can potentially unite us with another Earth. Unfortunately this is the first one I have found about any kind of research with solar panels in media. 
  • Several upcoming missions aim to harness the subtle push of sunlight, using gossamer "solar sails" to cruise through the heavens like boats through the sea.
  • A spacecraft equipped with a sail 1,300 feet (400 meters) wide, for example, could travel 1.3 billion miles (2.1 billion kilometers) per year, allowing it to escape the sun's sphere of influence in just a decade or so, according to researchers behind the Interstellar Probe, a NASA concept mission proposed about 15 years ago.

Pythagoras - Wikipedia, the free encyclopedia - 0 views

  • Pythagoras of Samos (/pɪˈθæɡərəs/; Ancient Greek: Πυθαγόρας ὁ Σάμιος Pythagóras ho Sámios “Pythagoras the Samian”, or simply Πυθαγόρας; Πυθαγόρης in Ionian Greek; c. 570 BC – c. 495 BC)[1][2] was an Ionian Greek philosopher, mathematician, and founder of the religious movement called Pythagoreanism.
  • Since the fourth century AD, Pythagoras has commonly been given credit for discovering the Pythagorean theorem, a theorem in geometry that states that in a right-angled triangle the area of the square on the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares of the other two sides—that is,
  • While the theorem that now bears his name was known and previously utilized by the Babylonians and Indians, he, or his students, are often said to have constructed the first proof. It must, however, be stressed that the way in which the Babylonians handled Pythagorean numbers implies that they knew that the principle was generally applicable, and knew some kind of proof, which has not yet been found in the (still largely unpublished) cuneiform sources.[47]

  • According to legend, the way Pythagoras discovered that musical notes could be translated into mathematical equations was when he passed blacksmiths at work one day and thought that the sounds emanating from their anvils were beautiful and harmonious and decided that whatever scientific law caused this to happen must be mathematical and could be applied to music. He went to the blacksmiths to learn how the sounds were produced by looking at their tools. He discovered that it was because the hammers were "simple ratios of each other, one was half the size of the first, another was 2/3 the size, and so on."
  • Another belief attributed to Pythagoras was that of the "harmony of the spheres". Thus the planets and stars moved according to mathematical equations, which corresponded to musical notes and thus produced a symphony.[51]

China and Nigeria: Neo-Colonialism, South-South Solidarity, or Both? | Daniel Wagner - 0 views

  • Bilateral relations between China and Nigeria will likely take one of two paths in the long term: either China will remain the overwhelmingly dominant actor or Nigeria will become a regional superpower, evening out the playing field. If China remains the stronger player it will shape Nigeria in its own interests (commonly referred to as "Chinese Imperialism").
  • During the first eleven years of its independence, Nigeria and China had no diplomatic relations. The Nigerian government's view of China grew especially sour after Mao officially supported the secessionist state in Biafra by supplying the Biafran administration with weapons.
  • During the period of General Abacha's military rule (1993-1998), Beijing's no-strings-attached development projects were increasingly well received. Nigeria's leaders grew resentful of Western conditions for aid and investment, and many Nigerians began to question what a generation of economic dependence on the West achieved for Nigeria.
  • ...10 more annotations...
  • Abuja subsequently adopted a new approach to international trade, balancing traditional Western partners and China.
  • The evolution of Nigerian-Chinese relations mirrors that of China's relationship with other African states (such as Angola, Sudan, and Zimbabwe) that sought alternative forms of aid and development packages following the imposition of sanctions by Western nations based on alleged human rights violations.
  • Today, more than 200 Chinese firms operate in Nigeria.
  • China agreed to provide Nigeria with a soft loan of $1.1 billion loan in exchange for Nigeria agreeing to increase its daily supply of oil to China ten-fold (from 20,000 barrels per day to 200,000) by 2015.
  • China recently embraced a new foreign policy in West Africa that contrasts with its traditionally passive approach to the spread of Islamic terrorism and extremism in Africa. Last year a Chinese diplomat in Mali pledged support for the Economic Community of West African States (ECOWAS)'s military campaign to dislodge Al Qaeda-affiliate groups in northern Mali.
  • China's number one concern in West Africa is access to natural resources and new consumer markets
  • While many Nigerians consider China's growing presence to be nothing short of a God send, others have raised concerns about Nigerian sovereignty, bearing in mind the impact Chinese trade and investment has had on other African countries.
  • The Chinese model of importing its own workers to build infrastructure projects, for example, does not sit well with many Nigerians.
  • A number of Nigerians have also voiced objections to the "slave-like" labor conditions in Chinese-operated factories across Nigeria. Attention was first brought to these conditions when 37 Nigerian workers died after being trapped inside a locked Chinese-owned factory that caught fire in 2002
  • Western powers that claim a desire to help Nigeria develop are often perceived as insincere, with their own aid being viewed as an infringement on Nigeria's sovereignty, since it often comes with strings attached.

Spotify, YouTube, Streaming Services Are Killing Digital Downloads | TIME.com - 0 views

  • Now, with a deluge of  music streaming services letting fans listen to songs for free, the digital download may be going the way of the CD and the cassette tape before it.
  • U.S. digital track sales decreased for the first time ever in 2013, dropping from 1.34 billion to 1.26 billion, according to Nielsen SoundScan.

  • However, the music industry’s core problem—that lots of fans just don’t want to pay for music—remains an issue. Most people use the free, ad-supported version of Spotify, and the company recently expanded its free offering to mobile devices. The most popular platform for listening to music among young people is YouTube, which is almost entirely free.

Speed of light - Wikipedia, the free encyclopedia - 0 views

  • The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its value is exactly 299,792,458 metres per second, a figure that is exact because the length of the metre is defined from this constant and the international standard for time.[1]
  • The first quantitative estimate of the speed of light was made in 1676 by Rømer (see Rømer's determination of the speed of light).[83][84] From the observation that the periods of Jupiter's innermost moon Io appeared to be shorter when the Earth was approaching Jupiter than when receding from it, he concluded that light travels at a finite speed, and estimated that it takes light 22 minutes to cross the diameter of Earth's orbit. Christiaan Huygens combined this estimate with an estimate for the diameter of the Earth's orbit to obtain an estimate of speed of light of 220000 km/s, 26% lower than the actual value.[105]
  • Beginning in the 1880s several experiments were performed to try to detect this motion, the most famous of which is the experiment performed by Albert A. Michelson and Edward W. Morley in 1887.[128] The detected motion was always less than the observational error. Modern experiments indicate that the two-way speed of light is isotropic (the same in every direction) to within 6 nanometres per second.[129]

  • In 1972, using the laser interferometer method and the new definitions, a group at NBS in Boulder, Colorado determined the speed of light in vacuum to be c = 299792456.2±1.1 m/s. This was 100 times less uncertain than the previously accepted value. The remaining uncertainty was mainly related to the definition of the metre.[Note 8][104] As similar experiments found comparable results for c, the 15th Conférence Générale des Poids et Mesures (CGPM) in 1975 recommended using the value 299792458 m/s for the speed of light.[136]

Pythagorean theorem - Wikipedia, the free encyclopedia - 0 views

  • Pythagorean proof
  • he Pythagorean Theorem was known long before Pythagoras, but he may well have been the first to prove it.[6] In any event, the proof attributed to him is very simple, and is called a proof by rearrangement. The two large squares shown in the figure each contain four identical triangles, and the only difference between the two large squares is that the triangles are arranged differently. Therefore, the white space within each of the two large squares must have equal area. Equating the area of the white space yields the Pythagorean Theorem, Q.E.D.[7] That Pythagoras originated this very simple proof is sometimes inferred from the writings of the later Greek philosopher and mathematician Proclus.[8] Several other proofs of this theorem are described below, but this is known as the Pythagorean one.
  • Pythagorean triples Main article: Pythagorean triple A Pythagorean triple has three positive integers a, b, and c, such that a2 + b2 = c2. In other words, a Pythagorean triple represents the lengths of the sides of a right triangle where all three sides have integer lengths.[1] Evidence from megalithic monuments in Northern Europe shows that such triples were known before the discovery of writing. Such a triple is commonly written (a, b, c). Some well-known examples are (3, 4, 5) and (5, 12, 13). A primitive Pythagorean triple is one in which a, b and c are coprime (the greatest common divisor of a, b and c is 1). The following is a list of primitive Pythagorean triples with values less than 100: (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41), (11, 60, 61), (12, 35, 37), (13, 84, 85), (16, 63, 65), (20, 21, 29), (28, 45, 53), (33, 56, 65), (36, 77, 85), (39, 80, 89), (48, 55, 73), (65, 72, 97)

  • He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".[5]
  • On July 12, 1939, a few months before the beginning of World War II in Europe, Szilárd and Wigner visited Einstein[74] and they explained the possibility of atomic bombs, to which pacifist Einstein replied: Daran habe ich gar nicht gedacht ("I had not thought of that at all").[75] Einstein was persuaded to lend his prestige by writing a letter with Szilárd to President Franklin D. Roosevelt to alert him of the possibility. The letter also recommended that the U.S. government pay attention to and become directly involved in uranium research and associated chain reaction research. The letter is believed to be "arguably the key stimulus for the U.S. adoption of serious investigations into nuclear weapons on the eve of the U.S. entry into World War II".[76] In addition to the letter, Einstein used his connections with the Belgian Royal Family[77] and the Belgian queen mother[72] to get access with a personal envoy to the White House's Oval Office.[72] President Roosevelt could not take the risk of allowing Hitler to possess atomic bombs first. As a result of Einstein's letter and his meetings with Roosevelt, the U.S. entered the "race" to develop the bomb, drawing on its "immense material, financial, and scientific resources" to initiate the Manhattan Project. It became the only country to successfully develop an atomic bomb during World War II. For Einstein, "war was a disease ... [and] he called for resistance to war." By signing the letter to Roosevelt he went against his pacifist principles.[78] In 1954, a year before his death, Einstein said to his old friend, Linus Pauling, "I made one great mistake in my life—when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification—the danger that the Germans would make them ..."[79]

Tunisia: How Mohammed Bouazizi Sparked a Revolution - TIME - 0 views

  • arned an income from selling vegetables, work that he'd had for seven years.
  • But on Dec. 17 his livelihood was threatened when a policewoman confiscated his unlicensed vegetable cart and its goods. It wasn't the first time it had happened, but it would be the last. Not satisfied with accepting the 10-dinar fine that Bouazizi tried to pay ($7, the equivalent of a good day's earnings), the policewoman allegedly slapped the scrawny young man, spat in his face and insulted his dead father.

  • Humiliated and dejected, Bouazizi, the breadwinner for his family of eight, went to the provincial headquarters, hoping to complain to local municipality officials, but they refused to see him. At 11:30 a.m., less than an hour after the confrontation with the policewoman and without telling his family, Bouazizi returned to the elegant double-storey white building with arched azure shutters, poured fuel over himself and set himself on fire. He did not die right away but lingered in the hospital till Jan. 4. There was so much outrage over his ordeal that even President Zine el Abidine Ben Ali, the dictator, visited Bouazizi on Dec. 28 to try to blunt the anger. But the outcry could not be suppressed and, on Jan. 14, just 10 days after Bouazizi died, Ben Ali's 23-year rule of Tunisia was over.
  • Just as the young woman Neda Agha-Soltan became a symbol of Iran's green movement after she was shot while watching a demonstration two years ago, Bouazizi has become a popular symbol among Arabs. He is being emulated as well. There have been almost a dozen copycat self-immolations in several Arab capitals including Cairo and Algiers.
  • Jaber Hajlawi, an unemployed 22-year-old lawyer and one of Bouazizi's neighbors, leaned against the graffitied wall as he lit a cigarette. "We were silent before but Mohammed showed us that we must react," he says.
  • The demand echoes across town. About 300 feet away from the spot where Bouazizi set himself alight, young men in the hundreds gather every day, eager to express their views to anyone who pulls out a notebook. They have erected handwritten banners near portraits of Bouazizi. "We are all prepared to sacrifice our blood for the people," reads one.

  • An accidental president, who came to power because of Anwar Sadat's assassination on October 6, 1981, Mubarak initially calmed the public, stressed the rule of law, released political prisoners and encouraged parliamentary elections. However, as soon as he began his second term, in 1987, he refused to reform the constitution, extended the state of emergency, promulgated laws to exclude opposition parties from local councils and tightened the grip of the ruling National Democratic Party (NDP) over parliament. He denounced opposition groups for criticizing his policies and asserted, threateningly, "I am in charge, and I have the authority to adopt measures…. I have all the pieces of the puzzle, while you do not."1

They prosecuted civilians charged with nonviolent infractions, such as Muslim Brothers who met to prepare for professional syndicate elections or journalists who "slandered" regime figures. Police increasingly harassed people on the street, demanding bribes from shop owners and minivan drivers and free food from vendors and restaurants. They seized and beat people in order to coerce false confessions or to pressure them to become informers. They harassed people who came to the police station to get IDs or other routine documents, and they nabbed those who "talked back" to them.

  • All aspects of public life were controlled, ranging from censorship of cultural and media production to the operation of labor unions.
  • Workers were banned from striking and, since the change in the labor law in 2003, were often hired on short-term contracts, under which they had no medical — or social — insurance benefits. The monthly minimum wage had not been raised since 1984, when it was set at LE 35 (in 2011 the equivalent of $6).6 The ETUF enforced government policy rather than represented its millions of members.
  • Private-sector workers suffered even more, as the 2003 labor law failed to provide any protection to employees negotiating length of contract, salary level, hours at work, overtime compensation, vacation or lunch breaks. Workers often lacked health and injury insurance. Many private-sector firms forced new hires to sign, along with the contract, Form No. 6, which allowed the employer to fire them without warning, cause or severance pay.
  • The exclusion of opposition forces from the political arena in fall 2010 was accompanied by systematic crackdowns on the media, cultural expression and university life. The regime wanted to prevent critical commentary from being aired in independent newspapers and on private satellite stations. The government closed down 19 TV and satellite channels, hacked or blocked several websites, and pressured private businessmen to cancel outspoken critics' positions as editors, opinion writers and talk-show hosts. The Association for Freedom of Thought and Expression (AFTE) concluded: "The Ministry of Mass Media and Communication has tightened its fist over all media channels to markedly reduce the space for freedom of expression, especially [during and] after the last parliamentary elections."13
  • Already, press and cultural output were managed through myriad control boards. Journalists were beaten, jailed and/or fined if they investigated corruption or police brutality and were charged with incitement or libel when they criticized government policies or political leaders. AFTE also reported heavy-handed censorship of movies, plays and books.
  • The crackdown on university life accelerated after the 1979 student charter was amended in 2007 to give administrative bodies — and, behind them, the SSI — the right to bar students from running in university elections. By th

Plainclothes SSI officers quelled demonstrations as well as threatening and arresting student activists. Then, in October 2010, the government refused to implement the Supreme Administrative Court ruling that banned SSI guards from the campuses and also blocked anti-regime candidates from contesting seats in the student-union elections.15

  • Given the overwhelming power of the state, the severe restrictions imposed by the State of Emergency on public gatherings, and the unchecked violence by police and security forces, people were fearful of protesting in the streets. Nonetheless, there were many efforts to expose the conditions. Novels and films highlighted corruption, police brutality, urban poverty and sexual harassment.29 Some art exhibits displayed in-your-face paintings depicting torture and military repression. Human-rights groups reported on poverty in the countryside and cities, deteriorating environmental conditions, harassment of women and activists, restrictions on the press, police coercion, and thuggery during elections.
  • There was public outrage at the very public beating-to-death just before midnight on June 6, 2010, of 28-year-old Khaled Said, seized as he entered an internet café in Alexandria.35 Late that night 70 young men and women gathered across from the police station, demanding that the police be brought to justice. They received the usual response: beaten, dragged along the street, attacked by police dogs, and arrested. Protests continued throughout the summer: funeral prayers at Sidi Gaber mosque, attended by 600 mourners who spilled out into the street afterwards; a vigil outside the Ministry of Interior headquarters in Cairo; a silent protest along waterfronts and bridges throughout Egypt; and numerous violently suppressed protests in downtown areas not only involving well-known politicians and protest groups but also people who felt that Khaled Said could have been themselves, their son, or their grandson. A teenager reflected this perspective, saying: "This is an extraordinary case. This guy was tortured and killed on the street. I did not know him but I cannot shut up forever."36 "For the sake of Khaled! For the sake of Egypt!" (ashan Khalid, ashan masr) became a rallying cry, voiced in fear as well as in the determination to restore individual and collective dignity (karama). On the fortieth day commemorating his death, people shouted outside the High Court: "Our voices will not be silenced… We've waited for 25 years, but our condition has not improved. Tomorrow the revolution will come."37
  • Dozens of Facebook groups supported the cause, of which "We Are All Khaled Said" became the most famous. They circulated reports about poli
  • ce brutality, many of which had been posted in the past but had not received such intense scrutiny. These included the video of police sodomizing a 21-year-old minivan driver in January 2006. Filmed by police officers in Boulaq al-Dakrour station, the police mailed it to the cell phones of other van drivers to intimidate them. "Everybody in the parking lot will see this tomorrow," they boasted.38 Hafez Abu Saeda, head of the Egyptian Organization of Human Rights, noted: "Police brutality is systematic and widespread… The humiliation of the simple citizen has become so widespread that people are fed up."39 Their anger, he warned, could spark a rebellion.
  • Nonetheless, the protesters themselves agree that it took the swift removal of Ben Ali to make them think that, if sudden change was possible in Tunisia, it might be possible in Egypt.
  • Even when people broke the barrier of fear on January 25, played cat-and-mouse with security forces on downtown streets on January 26 and 27, and withstood the onslaught all day and night on January 28, they faced a formidable regime, supported by the security forces and the entrenched NDP. The revolution would have been much bloodier if the armed forces had stood by the president. President Mubarak and Interior Minister Habib al-Adly hastened their own demise by unleashing extreme violence on January 28, followed by Adly's abrupt withdrawal of all police forces that night. Enraged, the public created neighborhood watches to ensure the safety of their communities.
  • Mubarak miscalculated by ordering the armed forces into the streets, even though their loyalty was to the nation — not to the person. He further miscalculated that he could offer minor concessions — such as appointing a vice president, changing the prime minister, and saying that he would not seek another term — on January 28 and again on February 1 and yet follow those placating words by unleashing fierce attacks on February 2. Over the next week, protesters held their ground, thousands of people flooded to city squares to call for dignity and freedom, labor strikes spread, employees in public institutions joined the movement, and lawyers, doctors, and professors marched in their professional garb. Finally, the Supreme Council of the Armed Forces ended its silent watch and forced Mubarak's hand. When Mubarak resisted leaving, the generals compelled the newly-appointed vice president to inform the president that, if he didn't step down, he would face charges of high treason.
  • Suddenly on Friday, February 11 — as millions of people surged angrily through the streets — Mubarak vanished. Anger transformed into tears of joy and celebration. And the next morning, young people cleaned up the public spaces, symbolically starting the huge task of cleansing Egypt of the corrupt regime and rebuilding the country. How they would rebuild Egypt remained uncertain, but their mobilization instilled a new and powerful pride, coupled with determination to take control over their future and not be cowed again by any authoritarian ruler.

NASA budget 2015: More cuts, more politics. - 0 views

  • In 2014 NASA got a total of $17.646 billion. The 2015 request is for $17.460 billion, a reduction of $186 million dollars, or about a 1 percent cut. That could’ve been worse. As we’ll see, though, it’s where those cuts are going that are bad.
    • Virinchi Tadikonda
       
      A reason for the lack of media coverage can be actually due to NASA not spending as much money to use for missions. A cut down of missions lead to less media coverage for typical launches unless major launches occur, such as a mission to the moon.

      Commercial Spaceflight by NASA is defined as flights that are for satellite repair and launching. This means that you can see crews up in space to repair GOES-R, Hubble, ISS, and other kind of satellites. 
  • Earth Science: cut by $56 million (given that so many in Congress are climate change deniers who want to cut Earth-observing missions, I think this may be a mistake). Astrophysics: cut by $61 million (including mothballing the wonderful SOFIA aircraft unless a German partner can pony up the cash; see page 15 of the report). Planetary Science: cut by $65 million. That last one is almost a victory, given how the White House has tried to eviscerate planetary exploration over the past few years. But don’t be fooled; these cuts would hurt. A lot. (Note added after I wrote this article but before it was posted: Casey Dreier at The Planetary Society has more on this situation.)
    • Virinchi Tadikonda
       
      This paragraph alone shows how space exploration is going downhill, and that such explorations are not necessary. Astrophysics and Earth Science are two major fields that require much research for space exploration. Without either or a lack of information from either departments due to cuts, this just spells bad news. 
  • Again, let me remind you that this is a budget request. Congress will have a different budget for NASA,
    • Virinchi Tadikonda
       
      This is a budget request, but the government is much more stingy. These numbers for cuts can be much higher without any warning.
