Surprisingly simple scheme for self-assembling robots

Via Instapundit and PhysOrg:

Known as M-Blocks, the robots are cubes with no external moving parts. Nonetheless, they're able to climb over and around one another, leap through the air, roll across the ground, and even move while suspended upside down from metallic surfaces.

Inside each M-Block is a flywheel that can reach speeds of 20,000 revolutions per minute; when the flywheel is braked, it imparts its angular momentum to the cube. On each edge of an M-Block, and on every face, are cleverly arranged permanent magnets that allow any two cubes to attach to each other.

The best economics primer you’ll ever see

Via Business Insider:

As part of his mission to explain how the economy works, Dalio has put together a neat, new 30-minute animated video called "How the Economic Machine Works," where Dalio narrates his big-picture view of the economy.

"I feel a deep sense of responsibility to share my simple but practical economic template," Dalio says. "Though it's unconventional, it's helped me to anticipate and sidestep the financial crisis, and it has worked well for me for over 30 years.”

Points:

  • Forces that drive the economy.
    • Productivity growth.
    • Short term debt cycle.
    • Long term debt cycle.
  • Transactions. Buyer exchanges cash or credit with seller for goods and services.
    • Cash + credit = total spending. Total spending drives the economy.
    • Total spending / total quantity sold = price.
  • Market. Buyers and sellers making transactions for same thing, e.g., wheat, gold, autos, etc.
    • All the markets = the economy.
    • Biggest buyer = government = central government + central bank.
  • Credit. Most important part of economy and least understood because biggest and most volatile.
    • Debt. When credit is created.
    • Creditworthy borrower = ability to repay + collateral.
    • Bad when it finances overconsumption that can’t be paid back.
    • Good when it leads to increased income to pay back debt.
  • Cycles.
    • Productivity matters in the long run.
    • Credit matters in the short run.
      • Short term debt cycle = 5-8 years.
      • Long term debt cycle.
        • Leveraging = 50+ years.
        • Depression = 2-3 years.
        • Reflation = 7-10 years.
  • Deleveraging is not recession. Debt burden has become too large to relieve by lowering interest rates. Borrowers and lenders start to realize debt is too large to be paid back. Remedies contain own risks:
    • Cut spending.
    • Reduce debt through default and restructuring.
    • Redistribute wealth from haves to have-nots.
    • Print money.
  • Rules of thumb.
    • Don’t let debt rise faster than income.
    • Don’t let income rise faster than productivity.
    • Do everything to raise productivity.

The Unrise of the Creative Working Class

Via NewGeography:

What will save the Clevelands and Detroits? The most prescribed cure is to find a way to attract more educated people. This has led cities across the country to compete for the vaunted “creative class” professional demographic. To urban theorist Richard Florida, to get creative types a city must have “[an] indigenous street-level culture – a teeming blend of cafes, sidewalk musicians, and small galleries and bistros, where it is hard to draw the line between participant and observer or between creativity and its creators.”

According to Florida, a city needs to know it is on stage,and compete for the attention of a select demographic. In theatre parlance, this is called “capturing the audience experience.”  In urban place-making parlance it is called  “principles of persuasion” that emphasize novelty, contrast, surprise, color, etc.

However:

  • “…Florida himself acknowledged this, stating in Atlantic Cities that, “On close inspection, talent clustering provides little in the way of trickle-down benefits [to the poor].”  In fact, because housing costs rise, it  makes the lives of lower- and middle-income people worse.”
  • “…cities keep revitalizing this way because it is a feel-good prescription that is politically palatable. Who hates art, carnivals, drinking, and eating?”
  • “Where does that leave the millions operating on the wrong side of scarcity? Florida’s answer is for cities to somehow convince corporate America to pay their service workers more.”

Enabling innovation

Via Chief Learning Officer:

…there are five key skills of disruptive innovators: associating, questioning, observing, networking and experimenting. These make up “the innovator’s DNA,” a set of behaviors that anyone can practice to consistently develop innovative ideas and become discovery-driven thinkers…[and] to scale innovation from an individual to an organizational level, leaders must imprint their organizations with their own innovator’s DNA.
