More dry wit from scientists:
"The book of Ecclesiastes says: “Is there any thing whereof it may be said, See, this is new? It hath been already of old time, which was before us.” As the job of the scientists is to discover new things, they are the most affected. In this paper we report a case study."

I love the dry humor of scientific writing!

"Culturomics, and the study of human culture in general, seemingly has little to do with deterministic chaos and fractals. However...."

It was just an interpretation problem after all...

As a scientist who has worked in startups, hospitals, and small colleges, nothing has been professionally more frustrating than the inability to access the latest research. Why would we want to keep the latest medical discoveries, paid for at taxpayer expense, from our doctors? Why would we want to keep them from the engineers and inventors who are developing the next big thing? Why else is the government funding basic research if not to aid development, inform the public, and guide medical treatment?

Here is a petition at the White House to support that government funded research must be made available to the public that funds it. Please sign!

why doesn't it feel like progress?

If you remember, or look back through my stream, I had asked on this for people to recommend a text on digital signal processing. You may also remember that I have complained about the monopolistic pricing schemes of academic publishers.

I'm pleased to recommend Digital Image Processing: Mathematical and Computational Methods by Jonathan M. Blackledge. Dr. Blackledge has been generous enough to make his book available as a Creative Commons license. He also has another CC book on Digital Signal Processing.

I'm still halfway through the book, but one thing that I've appreciated about it is that it starts with a physics basis, beginning with topics like Maxwell's equations and layered seismology theory, projection tomography and syntehtic aperture imaging to derive the physical basis of different types of images.

This book is available in print for $130 at Amazon. It is a 700 page tome and clearly the result of a lot of work by the author. It was clearly typeset and edited by the author in LaTeX (and looks great!). I wonder how the economics of its production work.

This video got me thinking about the world-wide nature of the Occupy Wall Street protests. It shows how Israel is raging in such a familiar manner against the corrupt hold that elites have on its society. The video is called "The Israel Machine".

The people who bop around are leaders of different Israeli political parties: Prime Minister Bibi Netanhayu of right-wing Likud, Foreign Minister Avigdor Liberman of hardline Our Home is Israel party, Minister of Internal Affairs Eli Yeshai of the religious Shas party, Defense Minister Ehud Barak (recent leader of the Labour party), and Opposition Leader Tzipi Livni of the Kadima party.

The leaders bop around on valves labeled "Prime Minister", "Foreign Minister" and the like.

Election after election, the same elites still run the country, just shifting who sits where.

The animations of the machine are pretty self-explanitory, but I had trouble with the last two, which refer to the walling off of the Palestinians and the deportation of the foreign (often Thai) guest-workers brought in to replace them.
