‘Veggie’ Experiment Launching to Station Aboard SpaceX Cargo Craft

NASA – The International Space Station’s Vegetable Production System (“Veggie”) experiment is on display in the News Center at NASA’s Kennedy Space Center in Florida.

Veggie is a new investigation with “edible results” heading to the space station. Veggie is a deployable plant growth unit capable of producing salad-type crops to provide the crew with appetizing, nutritious and safe fresh food and support crew relaxation and recreation. It will serve as a new space station facility as well and will provide a venue for future plant growth research.

To the right of the Veggie experiment is a model of the Space Launch System (SLS), the nation’s next heavy-lift launch vehicle. NASA is developing the SLS and Orion spacecraft to provide an entirely new capability for human exploration beyond low-Earth orbit, with the flexibility to launch spacecraft for crew and cargo missions, including to an asteroid and Mars.

The Veggie experiment is aboard SpaceX’s Dragon cargo spacecraft, scheduled to launch atop a Falcon 9 rocket from Launch Complex 40 at Cape Canaveral Air Force Station, Fla. at 4:58 p.m. EDT on Monday, April 14, 2014. The SpaceX-3 mission is carrying almost 2.5 tons of supplies, technology and science experiments and is the third of 12 flights contracted by NASA to resupply the orbiting laboratory.

The Most Valuable Management Degree Doesn’t Exist


By Adam Grant – Once upon a time, the field of medicine was riddled with danger. Doctors made up cures based on individual experience, inflicting horrors on patients—lobotomy, anyone?

Everything changed with the advent of evidence-based medicine.

With randomized, controlled trials and careful longitudinal studies, we learned about effective treatments and risky behaviors.

Today, the field of management is not far from where doctors were before evidence-based medicine.

We have leaders and managers choosing practices based on their own intuition and experience, when it’s much more reliable and valid to make decisions based on many data points and experiences. more> http://tinyurl.com/nouuytj

Far from messing with our brains, the internet has set our minds free


By Bryony Gordon – .. now we have the internet, a vast, shadowy, invisible mass of… stuff , which serves as a convenient scapegoat for all society’s ills.

Violent behaviour? Blame the internet. A generation of stupid children? That’ll be the internet. Fleeting attention spans? Internet, internet, int- hang on, I’ve just received a tweet. Better check it.

We are derogatory about the accuracy of Wikipedia, without stopping to think about what a minor miracle it is that people actually devote their free time to the altruistic cause of providing information to others. more> http://tinyurl.com/qcl6byf

BOOK REVIEW

The Story of an Accidental Revolution, Author: Linus Torvalds.

By Leonid Bershidsky – Linux [2, 3] creator Linus Torvalds wrote, “in a society where survival is more or less assured, money is not the greatest of motivators. It’s been well-established that folks do their best work when they are driven by a passion.”

Two conclusions follow.

First, where there are people passionate enough about a product to work for free, others will claim their work and use it for profit because they are equally passionate about money.

Second, open-source software will never be painstakingly debugged: No one is passionate about that kind of drudgery.

This does not mean commercially-produced software is free from bugs, but at least paid developers bear responsibility for the products. more> http://tinyurl.com/kxt58eg

When credit is too much of a good thing


By Edward Hadas – What does credit do after it has finished the job it was designed for?

The supply of credit ought to stop at funding productive activity.

But the reality is different. Surplus credit fuels dangerous asset price inflation and funds profligate governments.

Credit too easily goes astray and there is no natural force to rein it in. Without firm regulatory guidance, credit seems to expand indefinitely, until the financial system explodes. That has been the pattern since the end of the Second World War. more> http://tinyurl.com/pyl26kh
