The pure in heart

Among the evils that circulate are not the networks, but also the gossip and 
the evils of the contemporary world is the distrust, it would not be exaggeration to say that it is the “Society of Mistrust.”
If someone is not a certain group should be isolated, perhaps have some problem other forms of collective bullying that help to isolate the person and make him feel bad, many times about the mantle of sweet words.
There are many young people and old people who feel bad in their own environment, there is a lack of love camouflaged in apparent good intentions, we must not proselytize and accept the Other as he is, much has been said in philosophy and society about this in concepts such as: relationships, empathy, listening and dialogue, but the result is small.
All those who act against the negative current feel in their hearts a new peace, even in the midst of so many difficulties, feel a new impulse to move forward in the midst of a world full of suspicion.
It is as the beatitudes say in the famous sermon on the mountain, where two special ones to this day Mt (5: 8-9):
“Blessed are the pure in heart: for they shall see God.
Blessed are the peacemakers, for they will be called children of God. ”
Promote peace and say words of encouragement to everyone around you and reap tasty fruits.
Autonomous robots?

Autonomous robots are a denomination for those who are within the environmental
limits, can achieve the desired goals (by humans or by tasks organized in an algorithm) in these unstructured environments without a human help, by this they are in certain levels.
For example, within a factory where mechanical tasks are performed, to avoid accidents, their geographic space is limited and deficient to detect the defect that can be fulfilled by a forged task, since a space robot should have fewer limits and be the most autonomous autonomous, for being without possibility of direct human action and having communication difficulties due to a distance.
The project called SWARM, funded by the European Union and we have already made a post, now has the first multi-robot system of autonomous assembly that has sensory-motor coordination observing similar robots around them, they will vary in shape and height in white according to a task and / or work environment.
A central “cerebral” central coordinating system, all of us, through a system called MNS (Mergeable Nervous System), and thus are reconfigured observing different capacities but combined by a single central controller.
They can also split up and perform self-repair tasks, eliminating defective body parts, including a brain unit with some defect, of course, one can define which are defeats and self-repairs.
In autonomous robots, learning and strategy according to the environment, what you can do with your autonomy increases, but for what you can print, the article is still not the case.
The current model has 10 units, and the authors point out without paper published in Nature Communications, claim that the Project is scalable, both in terms of computational resources for robotic control and time of reaction to stimulus, whithin the system.
How are cyber-brain searches?

There is a lot of research mapping the brains, and investigating aspects of how certain 
functions work such as: motor function, vision, and in a very special way the
Cognitive Neuroscience studies the cognitive ability (knowledge) of a person, such as reasoning, memory and learning.
A recent study by the Universities of Exeter and Oxford of the United Kingdom, in conjunction with the University of Munster in Germany, has developed photonic microchips that immitate the synapses of the human brain using light and no longer electricity, as in other chips.
The chips is manufactured using the frequency phenomenon, but from the combined phase shift in the integrated photonic circuits designed for this, with synapses can operate at 1,000 times the speed of humans, which does not mean they do the same.
The researchers say that it is a fundamental step in machines capable of functioning and in the way of thinking in a way similar to the brain since the photon is fast and low energy consumption.
David Wright told the University of Exeter website that the project addresses two important issues in electronic computing, both speed and efficiency and capacity problems in parallel processing, the fastest of now: ” not only by developing…new brain-like computer architectures, but also by working in the optical domain to leverage the huge speed and power advantages of the upcoming silicon photonics revolution “
On-chip photonic synapse by Zengguang Cheng, Carlos Rios, Wolfram Pernice, C David Wright and Harish Bhaskaran is published in Science Advances.
