In his research, too, Mandelbrot often chose unfriendly territory. One of his first interests at IBM was studying economic patterns, like income distribution and price changes. When he studied fluctuations in cotton prices in the nineteenth century, he got a first glimpse of the discovery that would make him famous: the intricately nested nature of our universe. Simple shapes are inhuman. They fail to resonate with the way nature organizes itself or with the way human perception sees the world.”
The New York Times Magazine (Nathan Lane...Producers , CONNECTED...LIfe In The Wireless Age, April 22 , 2001)The Information, as I see it, is about just that, extraordinary people seeing the patterns first, forming a theory, beginning their proofs, and others building on those proofs until new understandings emerge. It’s an exciting and wonderful journey!
Lorenz dubbed it the butterfly effect. This means systems like our weather are so sensitive to small disturbances that a butterfly flapping its wings in Beijing today could be responsible for a raging storm next month in New York. In science-speak, this is also known as “sensitive dependence on initial conditions” – and it became the cornerstone of the new field of chaos theory. A group of young mathematicians at Santa Cruz used computer visuals and everyday phenomena to popularize chaos theory. Sve je to vrlo interesantno, umešno napisano i razborito objašnjeno, ali je i dalje tek za lestvicu iznad laičkog poznavanja teme. Funkcioniše kao uvod i zanimljiva istorija, kao upoznavanje sa nelinearnom dinamikom, ali ne mnogo više od toga. His discussion of Turing, not just his test but also his machine and incalculable numbers, is highly readable and clear. His discussion of Gödel is somewhat less clear, but than I’m yet to have read a perfectly clear description of the incompleteness theorem – which might say more about me than it does about the descriptions I have read, who knows. This one is still good, even if it remains over my head. However, there is a wonderful discussion of the relationship between information and entropy and why entropy is an important concept for people to understand, as good an explanation as any I have ever read.

Scientists like to have their expectations thwarted about as much as the rest of us. And they certainly weren’t expecting that some of the most fundamental physical systems in our world behave in completely chaotic, unpredictable ways. So naturally, most of them weren’t too thrilled about this new chaos theory embraced by younger, freethinking scientists from the 1970s onwards. The New York Times Magazine (The Future Is Here vs The Information Stone Age , Euthanasia and Abortion, May 16 , 1993) They’d no idea how fragile, unstable, and chaotic physical systems like the Earth’s weather really are. It took a mathematically-minded meteorologist to demonstrate this. Psinet to Sell Consumer Internet Division". The New York Times. July 2, 1996 . Retrieved March 23, 2009.
Here’s the key message: Meteorologist Edward Lorenz became the intellectual father of chaos theory after discovering the unpredictability of weather.Somehow, after all, as the universe ebbs toward its final equilibrium in the featureless heat bath of maximum entropy, it manages to create interesting structures.” What the telegraph accomplished in years the telephone has done in months. One year it was a scientific toy, without infinite possibilities of practical use; the next it was the basis of a system of communication.... In fairness, there was a long gap where I put this book down after having read the first half, so I recognize that I lost the continuity of the narrative. And maybe, just maybe (highly doubtful!!)I'm just not smart enough to get it. Still, a whole lot more could have been done to illustrate the application and implications of the subject. I also didn't care for the tone of the brief profiles of the various physicists and mathematicians - it felt like name-dropping to me.
