Ancient Greek Technology 1,000 Years Early

Antikythera Mechanism - Ancient Greece

Although its origins are uncertain, the new studies of the inscriptions suggest it would have been constructed around 100-150 BC…

Writing in Nature, the team says that the mechanism was “technically more complex than any known device for at least a millennium afterwards”.
…
the Moon sometimes moves slightly faster in the sky than at others because of the satellite’s elliptic orbit. To overcome this, the designer of the calculator used a “pin-and-slot” mechanism to connect two gear-wheels that introduced the necessary variations.

“When you see it your jaw just drops and you think: ‘bloody hell, that’s clever’. It’s a brilliant technical design,” said Professor Mike Edmunds.

Report on Use of Online Science Resources

The Internet as a Resource for News and Information about Science (pdf) from the Pew Internet & American Life Project:

“40 million Americans rely on the internet as their primary source for news and information about science,” second to TV.

Another interesting piece of data: “59% of Americans have been to some sort of science museum in
the past year.” I find this unlikely but… That rises to79% for those that have visited a science website.

The respondents also reported extremely positives views of science, such as (see page 26-28):
To be a strong society, the United States needs to be competitive in science 39% strongly agree 50% agree 8% disagree 1% strongly disagree
Developments in science help make society better 31% 58% 8% 1%
Scientific research is essential to improving the quality of human lives 35% 56% 7% 1%
Science creates more problems than solutions for us and our planet 3% 19% 52% 19%

Leadership Initiatives for Teaching and Technology

LIFT2 (Leadership Initiatives for Teaching and Technology) is an innovative professional learning program for middle and high school science, technology, engineering and math (STEM) teachers. It is designed to help experienced and developing teachers relate classroom curriculum to authentic and relevant applications in the 21st Century workplace.
The program is based on a unique combination of graduate coursework, company sponsored externships in industry, the cornerstone of the program, and membership in an active community of learners.

Why Desktop Linux Will Not Take off

I am getting a new computer and will use Ubuntu (a Linux flavor) as the operating system. I find this article interesting though I don’t necessarily agree. I think there is a decent chance that desktop Linux will take off in the next 3 years. Why Desktop Linux Will Not Take off, and Why You Don’t Want It to, Average computer buyers:

worst nightmare after melting in a lava pit might be to have to compare between distributions, desktops, window managers, file browsers, web browsers, mail clients, instant messaging clients, music players and movie players before they could do anything with their brand new desktop computer—or before they had a mental breakdown.

the Linux desktop has been designed and implemented by technology enthusiasts, for technology enthusiasts. If they were to seriously try to make it appealing to the masses, the effort would collapse halfway because they would be dismayed by the result. My take is that things are just fine the way they are, and the Linux desktop for Dummies an utopia.

The option is for a cover to be placed over the operating system that is easy for most to use. That is what Apple does. And that is what Ubuntu does (and Ubuntu is free). For me the likelihood of Linux desktop taking off is great especially when you consider how many of the new desktops will be placed in India, China, Brazil…

Web Science

MIT and University of Southampton launch World Wide Web research collaboration:

The Web Science Research Initiative (WSRI) will generate a research agenda for understanding the scientific, technical and social challenges underlying the growth of the web. Of particular interest is the volume of information on the web that documents more and more aspects of human activity and knowledge. WSRI research projects will weigh such questions as: How do we access information and assess its reliability? By what means may we assure its use complies with social and legal rules? How will we preserve the web over time?

Commenting on the new initiative, Tim Berners-Lee, inventor of the World Wide Web and a founding director of WSRI, said, “As the web celebrates its first decade of widespread use, we still know surprisingly little about how it evolved, and we have only scratched the surface of what could be realized with deeper scientific investigation into its design, operation and impact on society.

Tim Berners Lee continues to show great insight. Continue reading →

Google History

Google History @Google.com

Already Google.com, still in beta, was answering 10,000 search queries each day. The press began to take notice of the upstart website with the relevant search results, and articles extolling Google appeared in USA TODAY and Le Monde. That December, PC Magazine named Google one of its Top 100 Web Sites and Search Engines for 1998. Google was moving up in the world.
…
As 2000 ended, Google was already handling more than 100 million search queries a day — and continued to look for new ways to connect people with the information they needed, whenever and wherever they needed it.
…
In February of 2002, AdWords, Google’s self-service advertising system, received a major overhaul, including a cost-per-click (CPC) pricing model that makes search advertising as cost-effective for small businesses as for large ones. Google’s approach to advertising has always followed the same principle that works so well for search: Focus on the user and all else will follow.

The Next Generation Internet

Experts say U.S. must act on Internet. The results of a survey by Juniper Networks:

86 percent of a group of more than 1,000 experts on the next-generation Internet say they worry that the head start of other nations will hurt the United States.

They fear that China, India, and many European and Asian countries are moving faster to implement the addressing scheme known as Internet Protocol version 6, or IPv6.

iWoz

iWoz book cover image

iWoz, autobiography of Steve Wozniak, Apple co-founder is now available. Quote from Guy Kawasaki:

Every engineer—and certainly every engineering student—should read this book. It is about the thrill of invention, the process of making the world a better place, and the purity of entrepreneurship. I, Woz is the personal computer generation’s version of The Soul of a New Machine. It is, in a nutshell, the engineer’s manifesto. I hope that the so-called “innovation experts” and MBAs choke when they read it.

Google India Looking for Engineers

Google not finding right talent in India to suit its needs

Google, which is considered to have a very low attrition rate even in the high-job-hopping Indian IT space, has found it more challenging to hire certain talent in India as compared to other parts of the world, the company’s Founder-Director Kavitark Ram Shriram admitted recently.

The Indian origin founding board member of Google and a well-known venture capitalist said at an ‘investing in India’ conference in San Francisco, “I know first hand that we have had a bit more of a challenge trying to hire engineers for Google in Bangalore compared to the other parts of the world.”

Google even has a we’re hiring link on the Google India home page.

Recent articles also point to other companies having trouble finding Indian engineers to fill all the jobs they hoped to fill.
