However, all these functions suffer from what has been called Numbers 'the tyranny of numbers.'

  • When Is a Microprocessor Not a Microprocessor? the Industrial Construction of Semiconductor Innovation I
    Ross Bassett When is a Microprocessor not a Microprocessor? The Industrial Construction of Semiconductor Innovation I In the early 1990s an integrated circuit first made in 1969 and thus ante­ dating by two years the chip typically seen as the first microprocessor (Intel's 4004), became a microprocessor for the first time. The stimulus for this piece ofindustrial alchemy was a patent fight. A microprocessor patent had been issued to Texas Instruments, and companies faced with patent infringement lawsuits were looking for prior art with which to challenge it. 2 This old integrated circuit, but new microprocessor, was the ALl, designed by Lee Boysel and used in computers built by his start-up, Four-Phase Systems, established in 1968. In its 1990s reincarnation a demonstration system was built showing that the ALI could have oper­ ated according to the classic microprocessor model, with ROM (Read Only Memory), RAM (Random Access Memory), and I/O (Input/ Output) forming a basic computer. The operative words here are could have, for it was never used in that configuration during its normal life­ time. Instead it was used as one-third of a 24-bit CPU (Central Processing Unit) for a series ofcomputers built by Four-Phase.3 Examining the ALl through the lenses of the history of technology and business history puts Intel's microprocessor work into a different per­ spective. The differences between Four-Phase's and Intel's work were industrially constructed; they owed much to the different industries each saw itselfin.4 While putting a substantial part ofa central processing unit on a chip was not a discrete invention for Four-Phase or the computer industry, it was in the semiconductor industry.

    Silicon Valley Then and Now: To Invent The Future, You Must Understand The Past https://medium.com/backchannel/why-silicon-valley-will-continue-to-rule-c0cbb441e22f “You can’t really understand what is going on now without understanding what came before.” Steve Jobs is explaining why, as a young man, he spent so much time with the Silicon Valley entrepreneurs a generation older, men like Robert Noyce, Andy Grove, and Regis McKenna. It’s a beautiful Saturday morning in May, 2003, and I’m sitting next to Jobs on his living room sofa, interviewing him for a book I’m writing. I ask him to tell me more about why he wanted, as he put it, “to smell that second wonderful era of the valley, the semiconductor companies leading into the computer.” Why, I want to know, is it not enough to stand on the shoulders of giants? Why does he want to pick their brains? “It’s like that Schopenhauer quote about the conjurer,” he says. When I look blank, he tells me to wait and then dashes upstairs. He comes down a minute later holding a book and reading aloud: Page | 1 Steve Jobs and Robert Noyce. Courtesy Leslie Berlin. He who lives to see two or three generations is like a man who sits some time in the conjurer’s booth at a fair, and witnesses the performance twice or thrice in succession. The tricks were meant to be seen only once, and when they are no longer a novelty and cease to deceive, their effect is gone.

    NATIONAL FOUNDATION FOR AMERICAN POLICY NFAP POLICY BRIEF» O CTOBER 2017 IMMIGRANTS AND NOBEL PRIZES : 1901- 2017 EXECUTIVE SUMMARY Immigrants have been awarded 39 percent, or 33 of 85, of the Nobel Prizes won by Americans in Chemistry, Medicine and Physics since 2000. In 2017, the sole American winner of the Nobel Prize in Chemistry was an immigrant, Joachim Frank, a Columbia University professor born in Germany. Immigrant Reiner Weiss, who was born in Germany and came to the United States as a teenager, was awarded the 2017 Nobel Prize in Physics, sharing it with two other Americans, Kip S. Thorne and Barry C. Barish. In 2016, all 6 American winners of the Nobel Prize in economics and scientific fields were immigrants. These achievements by immigrants point to the gains to America of welcoming talent from across the globe. It does not mean America should welcome only Nobel Prize winners. Such a policy would be impossible to implement, since most immigrant Nobel Prize winners enter the United States many years before being awarded this honor. Most people immigrate to another country in their 20s, particularly employment-based immigrants, who either study in America or come here to work shortly after obtaining a degree abroad. The average of age of Nobel Prize winners at the time of the award is 59.5 years, according to economist Mark J. Perry.1 Table 1 Immigrant Nobel Prize Winners in Chemistry, Medicine and Physics Since 2000 Immigrant Nobel Winners Since 2000 33 of 85 American winners have been immigrants Percentage of Immigrant Winners Since 2000 39% Source: Royal Swedish Academy of Sciences, National Foundation for American Policy, George Mason University Institute for Immigration Research.

  • How Venture Capital Works by Bob Zider
    Accounting How Venture Capital Works by Bob Zider From the Magazine (November-December 1998) Invention and innovation drive the U.S. economy. What’s more, they have a powerful grip on the nation’s collective imagination. The popular press is filled with against-all-odds success stories of Silicon Valley entrepreneurs. In these sagas, the entrepreneur is the modern- day cowboy, roaming new industrial frontiers much the same way that earlier Americans explored the West. At his side stands the venture capitalist, a trail-wise sidekick ready to help the hero through all the tight spots—in exchange, of course, for a piece of the action. As with most myths, there’s some truth to this story. Arthur Rock, Tommy Davis, Tom Perkins, Eugene Kleiner, and other early venture capitalists are legendary for the parts they played in creating the modern computer industry. Their investing knowledge and operating experience were as valuable as their capital. But as the venture capital business has evolved over the past 30 years, the image of a cowboy with his sidekick has become increasingly outdated. Today’s venture capitalists look more like bankers, and the entrepreneurs they fund look more like M.B.A.’s. The U.S. venture-capital industry is envied throughout the world as an engine of economic growth. Although the collective imagination romanticizes the industry, separating the popular myths from the / current realities is crucial to understanding how this important piece of the U.S. economy operates. For entrepreneurs (and would-be entrepreneurs), such an analysis may prove especially beneficial. Profile of the Ideal Entrepreneur Venture Capital Fills a Void Contrary to popular perception, venture capital plays only a minor role in funding basic innovation.
