Just before 10 a.m. ET, astronauts aboard the space station successfully grabbed the capsule with a robotic arm. A little after noon ET, the pulled the Dragon into its docking space. NASA was webcasting, and we have embedded its feed in this post (our apologies if you're on a device that doesn't support the player). Earlier this week on All Things Considered, NPR's Nell Greenfieldboyce reported about the historic mission.

Rhode Island School of Design Living Earth Simulator will simulate the entire world Described as a “knowledge collider,” and now with a pledge of one billion euros from the European Union, the Living Earth Simulator is a new big data and supercomputing project that will attempt to uncover the underlying sociological and psychological laws that underpin human civilization. In the same way that CERN’s Large Hadron Collider smashes together protons to see what happens, the Living Earth Simulator (LES) will gather knowledge from a Planetary Nervous System (PNS — yes, really) to try to predict societal fluctuations such as political unrest, economic bubbles, disease epidemics, and so on. The scale of the LES, when it’s complete, will be huge. It is hoped that supercomputing centers all over the world will chip in with CPU time, and data will be corralled from existing projects and a new Global Participatory Platform, which is basically open data on a worldwide scale.

Fashion Design School:Fashion Marketing & Merchandising:Master & Courses in Italy - Polimoda.com Standard error of the mean When you take a sample of observations from a population, the mean of the sample is an estimate of the parametric mean, or mean of all of the observations in the population. If your sample size is small, your estimate of the mean won't be as good as an estimate based on a larger sample size. Here are 10 random samples from a simulated data set with a true (parametric) mean of 5. The X's represent the individual observations, the red circles are the sample means, and the blue line is the parametric mean. As you can see, with a sample size of only 3, some of the sample means aren't very close to the parametric mean.
