Assisted by instruments that can track in fine detail how parcels of fluid move, and by low-cost computers that can crunch vast amounts of data quickly, researchers have found hidden structures beyond Monterey Bay, structures that explain why aircraft meet unexpected turbulence, why the air flow around a car causes drag and how blood pumps from the heartâ(TM)s ventricles. In December, the journal Chaos will highlight the research under way to track the moving skeletons embedded in complex flows, known as Lagrangian coherent structures.
Other real-world applications of this type of macro-scale dynamical systems analysis are described, including work being done a the Hong Kong International Airport, modeling and predicting turbulent air flow to warn pilots."
But the recent drop is not as steep as it seems at first. I asked Shane Greenstein, an economist at Northwestern University's Kellogg School of Management who has written extensively about the computer industry, to take a look at the raw data upon which those numbers were supposedly based: the annual I.T. spending estimates published by IDC.
Mr. Greenstein's calculations produced a more moderate compounded annual growth rate of 11.6 percent for 1980 to 2000, instead of 17 percent. (Mr. Siebel's personal assistant said last week that the 17 percent in the Stanford talk came from a staff member who calculated from a reading of a chart, not from precise figures.)
When Mr. Greenstein looked at the full IDC data set, which goes back to 1961, and used other breakpoints to compare growth in earlier and later periods, he found that the most golden years of I.T. were in the 1960s, when use of mainframe computers spread widely. From 1961 to 1971, the compounded annual growth rate was 35.7 percent, more than three times the rate in the 1980-2000 period celebrated by Mr. Siebel.
The article goes on to point out the obvious, that the percentage growth of an industry will decline as the installed base rises over time. Absolute growth in IT will continue - though it may not be gangbusters of old, IT will never be stagnant.
As other posters here have pointed out, many, (many) industries depend on the support infrastructure that IT provides to work effectively and efficiently. This will not change overnight. While some of this infrastructure has been substantially commoditized over the last 10 years or so, there will always be challenges that non-technical team-members cannot solve themselves. These challenges will require the participation of and collaboration with technologists in organizations that want to function at the high-performance end of the bell curve.
For it's intended task, it's fantastic. That task being reading fiction. NOTHING ELSE
The Kindle's intended task is displaying the written word for reading. I happen to find it fantastic for reading. Reading fiction, non-fiction, periodicals, and work-related documents. Others apparently find the DX appropriate for non-fiction, as several universities are working with Amazon to put textbooks (....non-fiction?) on the device.
I have exactly zero (0) works of fiction on my DX. I have six or seven books (purchased), all non-fiction; a Project Gutenberg text (free), non-fiction; a $1.99 trial issue of a magazine, mostly non-fiction, some short works of fiction (The New Yorker); and several work-related documents in PDF format.
The New Yorker indeed has a navigable table of contents, as do other periodicals, based on several reviews I've read. PDFs do not behave the same way on the DX as on a computer, but as others have pointed out, this may be remediated with a software upgrade.
That lifespan increase had everything to do with development in medicine and a better healthcare network.
is not accurate.
Most of the improvements in mean lifespan are due to the development or improvement of public sanitation. Better healthcare and nutrition are both important contributors to improvements in lifespan, but don't reach the level of significance of public sanitation.
Anyone can make an omelet with eggs. The trick is to make one with none.
