direct realism

The Nature of Computation - Intellects Vast and Warm and Sympathetic: "I hand you a network or graph, and ask whether there is a path through the network that crosses each edge exactly once, returning to its starting point. (That is, I ask whether there is a 'Eulerian' cycle.) Then I hand you another network, and ask whether there is a path which visits each node exactly once. (That is, I ask whether there is a 'Hamiltonian' cycle.) How hard is it to answer me?" (via) [more inside]

Finite formula found for partition numbers

New math theories reveal the nature of numbers [1,2] - "We prove that partition numbers are 'fractal' for every prime. These numbers, in a way we make precise, are self-similar in a shocking way. Our 'zooming' procedure resolves several open conjectures, and it will change how mathematicians study partitions." (/.|via) [more inside]

the four-day workweek

The Environmental and Economic Pluses of the 4-Day Workweek: "Forget everybody working for the weekend. In Utah all government employees have shifted to a four-day workweek, and the state is calling it a win-win-win for its budget, workers and clean air. Utah has saved $1.8 million in electrical bills in the last year, the air has been spared an estimated 6,000 metric tons of carbon dioxide, and workers are thrilled. Eighty-two percent of them say they prefer the new arrangement, which still enforces the 40-hour week by requiring 10 or more hours a day Monday - [Thursday]. Is it time to ask your boss if you can take off Friday .... forever?" (via)
