World’s largest laser produces nuclear fusion!*
No, that’s not giant pencil. It’s the inside of a fusion reactor, where lasers are focused onto a tiny pellet of frozen hydrogen gas (image courtesy of the Lawrence Livermore National Laboratory). Those photos at the bottom show the capsule that contains this fuel. Here’s a video that explains how the giant laser system (housed at the National Ignition Facility) works:
*Have we harnessed the energy of the stars? Not quite. Strictly speaking, while more energy came from fusion than went into the hydrogen fuel, only about 1 percent of the laser’s energy ever reached the fuel. The process still used a lot more energy than it generated.

A lovely piece from a friend…
Every so often Dr. Friedlander would find a patient who had the mental capacity to fathom whatever was conveyed to him/her over the pressurized sobs of the accompanying family member, largely due to the fact that Dr. Friedlander was a specialist in neurological disorders. He rose fast to…
What is a saint? A saint is someone who has achieved a remote human possibility. It is impossible to say what that possibility is. I think it has something to do with the energy of love. Contact with this energy results in the exercise of a kind of balance in the chaos of existence. A saint does not dissolve the chaos; if he did the world would have changed long ago. I do not think that a saint dissolves the chaos even for himself, for there is something arrogant and warlike in the notion of a man setting the universe in order. It is a kind of balance that is his glory. He rides the drifts like an escaped ski. His course is the caress of the hill. His track is a drawing of the snow in a moment of its particular arrangement with wind and rock. Something in him so loves the world that he gives himself to the laws of gravity and chance. Far from flying with the angels, he traces with the fidelity of a seismograph needle the state of the solid bloody landscape. His house is dangerous and finite, but he is at home in the world. He can love the shape of human beings, the fine and twisted shapes of the heart. It is good to have among us such men, such balancing monsters of love.

Thousands of protesters gather to lay “earth table” from Galatasaray to Taksim Square to break their Ramadan fast while Turkish riot police blocked the entrance of Taksim Square and warn them to leave the area. The Revolutionary Muslims and Anti-Capitalist Muslims called for fast-breaking iftar dinner on Istiklal Street while the local municipality hosted a dinner in Taksim Square by the Gezi Park. People marched in the square and park after the withdrawal of the police.© Tolga Sezgin / NarPhotos
