Sounds good to me! (And the sponsoring news organization is <i>not</i> owned by R. Murdoch!)

Animating the Mathematical Logic of M.C. Escher For his 1956 Prentententoonstelling (Print Gallery), M. C. Escher started with "the idea that it must…be possible to make an annular bulge,” “a cyclic expansion ... without beginning or end.” He created a recursive drawing of a gallery displaying prints. One print in the gallery shows a seaport containing the original print gallery. He projected this image onto a cyclically expanding grid with curved lines folding inward.

A cool 2003 article in Notices of the AMS shows his original grid, an 'unfolded' version of the Escher drawing, and various permutations of the basic concept. As a companion to their 2003 article, B. de Smit and H. W. Lenstra have created a rad website and animations, one of which I have converted from AVi to GIF using VirtualDub for our viewing pleasure.

This picture-within-itself strange loop imagery is sometimes called mise en abyme or, more commonly, the Droste effect, after the recursive label on a brand of Dutch cocoa powder. Thanks to the mathematical exposition by de Smit and Lenstra, you can now find tutorials for creating your own images using programs like GIMP or Photoshop. A flickr group exists for such images.

Hahaha! It's like life... you don't get to turn it off! (Of course, there is always that little "X" button on the right corner of the browser tab....)
I love it that Escher seems to have intuited fractals.

It'll be a night similar to this one, rainy, warmish, a few leaves blowing in the road, maybe a little earlier in the year - and I'll have to curse my wonderful brother-in-law when I pull over, turn the engine off, place my hands on the top of the steering wheel, and watch the state trooper approach in my side view mirror.

"Is there a problem, officer?" I'll ask, politely.

"What was going on back there?" he'll reply.

"I was, well, I was trying to miss the frogs."

At this point, he'll probably narrow his eyes under his dripping smokey-bear hat.

"Step out of the car, please."

"You know, frogs are having a tough time right now," I'll say, hopefully. He won't reply. I'm the reason he's standing in the rain.

When I first heard that my brother-in-law makes my sister drive on wet, rainy nights because of the frogs, I laughed. "It's leaves," I said. "Oh no," she replied; "frogs do come onto the warm asphalt in wet rainy weather." I looked. She's right.

So now I am aware of the frogs hopping about on the wet road, and I feel the little bumps and hear the pops when one is caught under my car wheels.

Maybe the nice trooper will let me off with a warning; I hope he can laugh when he tells his comrades about it back at HQ....

Words have meaning. We throw them around as though they have no power, and expect others to hear what we mean but fail to say.

Words are virtual diamonds mined from the pressures of our inner selves. Before we share them, we should cut and polish and apply a sharp eye in search of flaws that twist our meaning and corrupt our message.

Take care with your words; they outlive you.

The ever-changing face of business.
Derya Unutmaz originally shared:
 
How do you fund a bunch of researchers, given that little of their work will be readily marketable and the real breakthroughs will often benefit your competitors more than yourself?

Through the years, different funding models have come and gone. At the end of the 19th century there was what I'll call the Marconi model. Marconi was an amateur tinkerer when he invented radio. He went on to become a legendary entrepreneur, creating a number of companies to implement his invention. Benz, Birdseye, Sikorsky...a lot of innovators started companies on the Marconi model. Sadly, it doesn't work very well today. Amateurs have been outclassed, and teams have mostly replaced individuals.

The ACLU issued a document clarifying your right to photograph in public. "When in public spaces where you are lawfully present you have the right to photograph anything that is in plain view. That includes pictures of federal buildings, transportation facilities, and police. Police may not delete your photographs or video under any circumstances." I'm moderate about the state looking at us, but we must be militant about looking back.

Flat wages, rising prices, easy credit....

Characteristically excellent +Henry Blodget post with the 4 (actually 5) charts that explain why the OWS protests are resonating. In brief:


1. Unemployment is at the highest level since the Great Depression (with the exception of a brief blip in the early 1980s).
2. At the same time, corporate profits are at an all-time high, both in absolute dollars and as a share of the economy.

3. Wages as a percent of the economy are at an all-time low.

4. Income and wealth inequality in the US economy is near an all-time high: The owners of the country's assets (capital) are winning, everyone else (labor) is losing.
Strong data; vast implications. Especially notable, to me: The spike in corporate profits and CEO pay and the relative drop in wage income was the result of deliberate policy choices made in 2001, not random market forces. The 1990s Clinton-era boom was good for corporate profits and CEO pay and also for wages, while the 2000s Bush-era recovery was great for corporate profits and CEO pay, but terrible for wages.
