Universe composition
The dark side of cosmology: Dark matter and dark energy 1. David N. Spergel* +[image: composicao do universo do que e feito o universo] - ABSTRACT A simple model with only six parameters (the age of the universe, the density of atoms, the density of matter, the amplitude of the initial fluctuations, the scale dependence of this amplitude, and the epoch of first star formation) fits all of our cosmological data . Although simple, this standard model is strange. The model implies that most of the matter in our Galaxy is in the form of “dark matter,” a new type of particle not ... mais »
Artificial Inteligence
[image: home bar] *http://people.idsia.ch/~juergen/* Since age 15 or so, Prof. Jürgen Schmidhuber's main scientific ambition has been to build anoptimal scientist through self-improving Artificial Intelligence (AI), then retire. He has pioneeredself-improving general problem solvers since 1987, and Deep Learning Neural Networks (NNs)since 1991. The recurrent NNs (RNNs) developed by his research groups at the Swiss AI Lab IDSIA & USI & SUPSI (ex-TU Munich CogBotLab) were the first RNNs to win official international contests. They recently helped to improve connected handwriting recogn... mais »

Light: particle and wave
The first ever photograph of light as both a particle and wave Mar 02, 2015 [image: The first ever photograph of light as both a particle and wave] (Phys.org)—Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior. Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natur... mais »
Benefit of Eating Salt
The Weird Benefit of Eating Salty Food - Alice Park @aliceparkny March 3, 2015 [image: 115788609]Andrew Unangst—Getty Images Too much salt can lead to heart disease, but there may be a healthy side to salt that hasn’t been appreciated — until now If you’re an average American, chances are that you’re eating too much salt. But the latest research — which, the scientists stress, is still in its early stages — hints that there may be some benefits to salt that have gone unnoticed. Salt, it seems, may be an ancient way for the body to protect itself against bacteria. Reporting in the... mais »
information overload and decision-making
information overload and decision-making 3/03/15 From:[image: delanceyplace | www.delanceyplace.com] Today's selection --from The Organized Mind by Daniel J. Levitin. We live in a world with 300 exabytes (300 billion billion) of information, an amount that is rapidly expanding to ever greater amounts from this already brobdingnagian level. And yet the processing capacity of the conscious mind is a mere 120 bits per second. This presents a challenge to not only our processing capacity, but also our decision-making ability: "Neuroscientists have discovered that unproductively and loss... mais »

Take a spherical object (the Earth) and try to represent it on a flat plane (paper), and some parts of the sphere are going to get stretched. On most maps, Canada and Russia get puffed up, while countries along the equator get shrunk. Every now and then, though, you stumble across a map that enlightens.
