It has the sound of epic myth, but it’s simply a description of the evolution of the cosmos as revealed by science in our time. And we, we who embody the local eyes and ears, and thoughts and feelings of the cosmos, we’ve begun at last to wonder about our origins. Star stuff contemplating the stars, organized collections of ten billion billion billion atoms contemplating the evolution of matter, tracing that long path by which it arrived at consciousness here on the planet Earth and, perhaps, throughout the cosmos. Our loyalties are to the species and the planet. We speak for Earth. Our obligation to survive and flourish is owed not just to ourselves, but also to that cosmos, ancient and vast, from which we spring.”……..

But that’s just not how it happens. People don’t learn in isolation. When I talk about independent learners, I don’t mean people learning alone. I’m talking about learning that happens independent of schools.&lt;/p&gt;

&lt;p&gt;[…]&lt;/p&gt;

&lt;p&gt;Anyone who really wants to learn without school has to find other people to learn with and from. That’s the open secret of learning outside of school. It’s a social act. Learning is something we do together.&lt;/p&gt;

&lt;p&gt;Independent learners are interdependent learners.&lt;/p&gt;”&lt;br/&gt;&lt;br/&gt; - &lt;em&gt;&lt;a href="http://www.brainpickings.org/index.php/2013/05/13/dont-go-back-to-school-kio-stark/" target="_blank"&gt;Don’t Go Back to School&lt;/a&gt; – a must-read on how to fuel the internal engine of lifelong learning.

&lt;p&gt;An interesting model of our solar system’s path as it travels through space in the Milky Way.&lt;/p&gt;
&lt;p&gt;Certainly a departure from usual models that show the Sun as a static object, which it certainly isn’t&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;I had no idea this was happening. Where are we going?&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;To fuck some shit up&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;Around the center of the Milky Way, which is heading towards the Andromeda Galaxy.  And our whole Local Group is moving towards the Virgo Cluster.&lt;/p&gt;
&lt;p&gt;But we’ll never actually reach the Virgo Cluster because space is expanding between us and them faster than we’re moving towards it.&lt;/p&gt;

&lt;p&gt;At a public lecture in Pittsburgh in 1934, four hundred lucky students were privy to a lecture by Albert Einstein, in which the great man mathematically derived his famous mass-energy equivalence equation: E=mc&lt;sup&gt;2&lt;/sup&gt;. What you see above is a photo from that lecture, and what is thought to be the only surviving photo that shows Einstein working on that derivation.&lt;span id="more-108307"&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;The photo was pulled from a halftone newspaper clipping by David Topper and Dwight Vincent of the University of Winnipeg, who discovered it in 2007. Sadly, everything is a bit fuzzy so you can’t really make out the famed equation itself. And even though the original article had a crisp picture of Einstein posing next to one of his blackboards, he’s next to the wrong one.&lt;/p&gt;
&lt;p&gt;Here’s a closer look at the man and the math. If you look closely, you’ll see the mass-energy equivalence in the lower left hand corner of the blackboard on the right:&lt;/p&gt;
&lt;p&gt;Fortunately, Topper and Vincent managed to take the blurry photo and reproduce both blackboards in their original paper. Here’s the math behind the magic, the derivation of mass-energy equivalence as presented by Albert Einstein.&lt;/p&gt;
&lt;p&gt;In case you’re wondering why the famous equation says Δ&lt;/p&gt;

&lt;p&gt;The &lt;strong&gt;bending of a light ray&lt;/strong&gt; &lt;strong&gt;depends&lt;/strong&gt; only on the &lt;strong&gt;angle&lt;/strong&gt; it hits the lens, and &lt;strong&gt;not on the thickness&lt;/strong&gt; of the glass. This means thick lenses can be &lt;strong&gt;made thinner&lt;/strong&gt;, as shown here.  This is called a &lt;strong&gt;Fresnel&lt;/strong&gt; lens, and is used to make magnifying sheets as well as in lighthouses.

&lt;p&gt;&lt;strong&gt;DIY bionics - making kids smile again.&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;See the joy in Liam’s eyes as he is grasping a ball with his right hand for the first time. By the time this &lt;a href="http://www.youtube.com/watch?v=WT3772yhr0o&amp;feature=youtu.be" target="_blank"&gt;cute fellow grows up&lt;/a&gt;, he will have a bionic hand that will be connected to his neural-system and be indistinguishable from his biological body; but for now all Liam cares about is being able to play ball. &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;The Ongoing Discussion of Technological Unemployment&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Recently on my other blog I wrote a couple of posts on what is now with increasing regularity called “technological unemployment” — &lt;a href="http://geopolicraticus.wordpress.com/2013/03/14/automation-and-the-human-future/" target="_blank"&gt;&lt;strong&gt;Automation and the Human Future&lt;/strong&gt;&lt;/a&gt; and &lt;a href="http://geopolicraticus.wordpress.com/2013/03/17/addendum-on-automation-and-the-human-future/" target="_blank"&gt;&lt;strong&gt;Addendum on Automation and the Human Future&lt;/strong&gt;&lt;/a&gt;. This is simply the…&lt;/p&gt;

How Will Adding Intelligence to Everyday Things...</title><description>&lt;img src="http://25.media.tumblr.com/007b90cf0cb8cd85ee1d33e769d71bef/tumblr_mml0ouBN6v1qzs4rbo1_500.jpg"/&gt;&lt;br/&gt;&lt;br/&gt;&lt;p&gt;&lt;a class="tumblr_blog" href="http://smarterplanet.tumblr.com/post/50095232900/how-will-adding-intelligence-to-everyday-things" target="_blank"&gt;smarterplanet&lt;/a&gt;:&lt;/p&gt;

&lt;p&gt;&lt;a href="http://bigthink.com/flash-foresight/how-will-adding-intelligence-to-everyday-things-change-your-world-2?utm_source=feedburner&amp;utm_medium=feed&amp;utm_campaign=Feed:%20bigthink/main%20(Big%20Think%20Main)" target="_blank"&gt;How Will Adding Intelligence to Everyday Things Change Your World?  Big Think&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;On a global level, we are adding connected intelligence to both machines and objects using chips, micro sensors, and both wired and wireless networks to create a rapidly growing “Internet of things” sharing real-time data, performing diagnostics, and even making remote repairs. Many jobs will be created as we add intelligent connected sensors to bridges, roads, buildings, homes, and much more. By 2020, there will be well over a billion machines talking to each other and performing tasks without human intervention.   &lt;/p&gt;
&lt;p&gt;Think of it this way: from phones to cars to bridges, embedded technologies are increasingly making the things we use smarter every day. For example, some of the newest cars use cameras mounted in the rear to see if something is in the way when you are backing up. If there is something in the way, the car will apply the brake even if you don’t or you are slow to react. Likewise, the concrete in new bridges has embedded chips that can let engineers know when the concrete is cracking, stressed, and in need of repair before the bridge collapses. In addition, sensors on the surface of the road going over the bridge will detect ice and wirelessly communicate the information to your car. If you don’t slow down, the car will slow down to a safe speed for you.&lt;/p&gt;
