Nice ideia. Could not fly in December to the north pole though.

Solar Powered Plane to Fly Across the US

On May 1, the world’s first solar-powered plane will take off from Moffett Field in Mountain View, California — the home of NASA’s Ames Research Center – and fly across the US to New York. Even though the Solar Impulse plane could probably fly non-stop, day and night with no fuel, instead it will make several stops in US cities such as Phoenix, Dallas, and Washington, D.C. This would be a kind of “get to know you” tour for the US while the founders of Solar Impulse, Swiss pilot Bertrand Piccard and and pilot Andre Borschberg, want to spread their message of sustainability and technology.

This gives us an idea on how small we are in the universe.

Interesting presentation on fractal brain theory. It is a 2 hours presentation. If you are interested in artificial intelligence you will like this.

The Fractal Brain Theory.
The best & longest lecture on neuroscience that I've watched in a long while.

This is a great presentation by Wai H. Tsang, in which he discusses his fractal brain theory and the unification of neuroscience with psychology. Wai comes across as both likable and incredibly knowledgeable throughout the entire piece, as he presents the emergence of a unifying and definitive Fractal Theory of Brain and Mind. A huge and mysterious gap in human understanding can finally be filled . . . and explains that the brain is a fractal computing architecture and reveals an elegant way of understanding the brain's structure and operation, showing the same basic fundamental structure and process, being repeated at all scales and all places in the brain. Something that leading brain researchers and artificial intelligence experts have only so far been able to hint at, are demonstrated clearly in this cutting edge talk . . . and show that behind the mind numbing myriad complexity of the brain lies a stunningly beautiful and elegant simplicity. We are even treated to how this might enable genuine Artificial Intelligences. 

I originally found the video here on Google+ and it sat in my Watch Later list for quite a while before I watched it. I'd intended to re-share the original Daniel Estrada post where I thought I'd found it but I seem to be mistaken about Daniel sharing it, and a search revealed both Alex Lightman and Brad Acker had also shared it so in the end I'm not sure where I originally saw it!

As can be seen, at nearly 2 hours this is a long video - although very watchable and engaging throughout in my opinion - and I watched it over two sessions on consecutive days. I think the first 90 minutes are compelling and certainly stimulating; Wai expertly (and accessibly) weaves together many concepts, phenomena, and data into a unified whole that is enjoyable to imbibe and get your head around. During the last 30 minutes the discussion rockets into the nature of consciousness and the Universe and was something that I found harder to follow; whereas I found the first 90 minutes pretty convincing, I found the final 30 minutes less so (Wai admits that it is pretty "out-there"). 

I remain open-minded to the consciousness theory and look forward to watching the talk again some time. From a functional perspective the effect of such a theory on the likely development of genuine AIs and intimate BCIs are something that I find particularly exciting.
