The brain's analogy as a computer may be no better, eventually, like those precedes it before, such as mechanic analogy, hydraulic analogy etc.
To claim that brain is an information processing computer is like claiming it is a thermodynamic system obeying the 2nd law of thermodynamics - true but also trivial and does not shed light on what makes brain special.

Gravitational waves

The rumors are true: LIGO has seen gravitational waves! Based on the details of the signal detected, the LIGO team estimates that 1.3 billion years ago. two black holes spiralled into each other and collided. One was 29 times the mass of the Sun, the other 36 times. When they merged, 3 times the mass of the Sun was converted directly to energy and released as gravitational waves.

For a very short time, this event produced over 10 times more power than all the stars in the Universe!

We knew these things happened. We just weren't good enough at detecting gravitational waves to see them - until now.

I'll open comments on this breaking news item so we can all learn more. LIGO now has a page on this event, which is called GW150914 because it was seen on September 14th, 2015:

You can see the gravitational waveforms here:

At left in blue is the wave detected in Livingston, Louisiana. At right in red is the wave detected in Hanford Washington. The detector in Hanford saw the wave a few milliseconds later, so it must have come from the sky in the Southern hemisphere.

This glass sphere might revolutionize solar power on Earth. This is 35% more efficient than current solar panels and is able to operate on cloudy days. It concentrates light by 10,000 times. - Follow us for more at: +Tech News Today
