By Danny Lewis – The experimental reactor was built during the height of World War II as part of the Manhattan Project, the army’s nuclear weapons program.
Led by physicist Enrico Fermi, who described the rudimentary reactor as “a crude pile of black bricks and wooden timbers,” CP-1 was built in a matter of weeks out of a large stack of graphite bricks and uranium pellets, with cadmium and iridium control rods inserted to keep it from going critical, Michael Byrne writes for Motherboard.
Fermi theorized that the uranium would act as fuel by emitting neutrons that would collide with the other uranium atoms in the pile and split them apart. The more atoms that split, the more energy they would release, which would in turn perpetuate the reaction. The graphite bricks would slow the uranium neutrons, making these collisions more likely; control rods absorbed the neutrons, allowing Fermi and his team to control the reaction. more> http://goo.gl/ZQ0z5l

By Karin Hurt – There are a few signs that your company has a culture founded on listening.
It takes time to develop, but here’s how to tell when it does.
- People at all levels are thinking about the business and sharing ideas, and solutions to challenges show up in surprising places—not just every blue moon, but regularly.
- A great idea is a great idea, regardless of who thought of it, and your company rewards whoever does—fairly.
- Employees at all levels are really listening to what customers are saying, and that includes negative feedback.
- When the call for questions goes out, the room doesn’t fall silent.
- No one freaks out when an exec shows up unexpectedly.
- No one is shocked by the employee engagement survey results.
- Employees don’t feel like value-generating machines, but actual humans who have mutually respected relationships with their employer.
Listening is one of the most important behaviors to build in a company’s culture. more> http://goo.gl/HsD1k9
