 | How do they make Silicon Wafers and Computer Chips? This shows how computer chips are made from silicon crystal, to wafer to chips. www.youtube.com is worth watching too. There used to be an episode of National Geographic documentary named "Naked Science" on youtube. It was about using synthetic diamond crystal in place of silicon as the chip substrate. Since diamond crystal can tolerate higher heat, a CPU can be over-clocked without the worry of a melt-down. If you like this video, you should also look up diamond based computer chips. 2008年03月05日再生回数 336030 |

 | what is silicon what is silicon Name Origin Latin silex, or silicis (meaning what were more generally termed "the flints" or "hard rocks" during the Early Modern era where nowadays we would say "silica" or "silicates") "Silicon" in different languages. Sources Silicon is the second most abundant element and comprises 25.7% of the earth's crust (oxygen is first). Makes up major portion of clay, granite, feldspar, mica, asbestos, quartz (SiO2), and sand. Primary producers are Austria, Italy, India, South Africa, Australia, Canada, the USA and Brazil. Every year around 5000 tons of electronics grade silicon is produced.Abundance Universe: 700 ppm (by weight) Sun: 900 ppm (by weight) Carbonaceous meteorite: 1.4 x 105 ppm Earth's Crust: 2.771 x 105 ppm Seawater: Atlantic surface: 0.03 ppm Atlantic deep: 0.82 ppm Pacific surface: 0.03 ppm Pacific deep: 4.09 ppm Human: 260000 ppb by weight 58000 ppb by atoms Uses Used in glass as silicon dioxide (SiO2). It is used as a semiconductor to make microchips for electronics (like your computer). Silicon is also used in solar cells, tools, cement, LCDs, grease and oils. History Silicon (Latin silex, silicis for flint, flint's) was first identified by Antoine Lavoisier in 1787, and was later mistaken by Humphry Davy in 1800 for a compound. In 1811 Gay-Lussac and Thenard probably prepared impure amorphous silicon through the heating of potassium with silicon tetrafluoride. In 1824, Berzelius prepared amorphous silicon using approximately the same method ... 2010年12月20日再生回数 4459 |

 | Secret History of Silicon Valley [Recorded: November 20, 2008] Today, Silicon Valley is known around the world as a fount of technology innovation and development fueled by private venture capital and peopled by fabled entrepreneurs. But it wasn't always so. Unbeknownst to even seasoned inhabitants, today's Silicon Valley had its start in government secrecy and wartime urgency. In this lecture, renowned serial entrepreneur Steve Blank presents how the roots of Silicon Valley sprang not from the later development of the silicon semiconductor but instead from the earlier technology duel over the skies of Germany and secret efforts around (and over) the Soviet Union. World War II, the Cold War and one Stanford professor set the stage for the creation and explosive growth of entrepreneurship in Silicon Valley. The world was forever changed when the Defense Department, CIA and the National Security Agency acted like today's venture capitalists funding this first wave of entrepreneurship. Steve Blank shows how these groundbreaking early advances lead up to the high-octane, venture capital fueled Silicon Valley we know today. 2008年12月04日再生回数 115887 |

 | SOPA: Silicon Valley vs. Hollywood in fight against online piracy act www.nma.tv The entertainment industry has long lobbied congress for tougher laws on piracy. It seems HR 3261, the Stop Online Piracy Act or SOPA was going to deliver the toughest penalties yet. Introduced by Texas congressman Lamar Smith, SOPA gives the government the authority to block whole websites for copyright infringement, rather than the existing system of take-down notices. This puts social websites such as Facebook, Twitter and Youtube in particular danger as it would be all but impossible to monitor all of their users. For a while, it seemed like SOPA was destined for easy passage in congress. But the bill's backers did not count on a populist campaign rising in opposition to SOPA. Tech companies came together in a rare show of solidarity to fight the bill. Even Microsoft, a company that has long called for tougher piracy laws, acknowledge that SOPA goes too far. The website Tumblr's campaign to get its users to call congress generated 87834 calls alone. The American Censorship Day campaign sponsored by Fight for the Future and the Electronic Frontiers Foundation was also very successful. Has the tide turned against SOPA? With powerful congressional figures such as minority leader Nancy Pelosi speaking out against the bill as well as the energetic online opposition, its prospects for passage seems less certain. However, users on the site Reddit are not taking any chances...they are in the process of building what they call 'meshnet', a network that will directly ... 2011年11月28日再生回数 77858 |

 | The Secret History of Silicon Valley Google Tech Talks December 18, 2007 How Stanford & the CIA/NSA Built the Valley We Know Today, presented by Steve Blank. How much does an average Googler know about the history of the place he/she works in - Silicon Valley? Come and test your knowledge. I have seen this talk and I assure you - even seasoned Silicon Valley veterans will find this story interesting. Silicon Valley entrepreneur Steve Blank will talk about how World War II set the stage for the creation and explosive growth of Silicon Valley, and the role of Frederick Terman and Stanford in working with government agencies (including the CIA and the National Security Agency) to set up companies in this area that sparked the creation of hundreds of other enterprises. Steve Blank spent nearly 30 years as founder and executive of high tech companies in Silicon Valley, most recently the enterprise software firm E.piphany. He has been involved in or co-founded eight Silicon Valley startups, ranging from semiconductors to video games, and personal computers to supercomputers. He teaches entrepreneurship at UC Berkeley's Haas School of Business, Columbia University and Stanford's Graduate School of Engineering. This talk was hosted by Boris Debic 2007年12月21日再生回数 205352 |
