The Information Revolution is not bloodless

From the most recent issue of Locus magazine, November 2009, talking about his most recent novel Makers:

The people in Makers experience a world in which technology giveth and taketh away. They live through the fallacy of the record and movie industries: the idea that technology will go just far enough to help them and then stop. That's totally not what happens. technology joes that far and them keeps on going. It's a cycle of booms and busts. There are some lovely things about when you're riding the wave and some scary things. The Information Revolution is not bloodless. There's plenty to like about the pre-Information era and a lot of that will go away. We can mourn it in the same way we mourn the knife sharpener who walked down the road with his wheel, the same way we mourn the passing of the lace tatter and all the other jobs that were made obsolete by one kind of technology or another. But we can mourn it without apologizing for the future that disrupted it.

Philosophy humanitarian approach to Religious Life

Indisputable, that the movement of history has happened a lot of destruction caused by war, hostility, hatred among mankind. This was originally set out from the problem that they think is right finally connected with a great disaster that followed.
Look at how the program today is a struggle going on in Palestine, Afghanistan and many other areas. They each hold in principle that ultimately dragged people on a more severe destruction.

  Humanism view of Islam, Jews and Christians actually lead to peace. Many of this paragraph which states both Jewish, Christian and Islam. God as the creator of the course all-wise in this case has highlighted the right rules and direction of human development both socially specific time within a single unit or in general in the multi-unit time. The interests of one class to that other group that eventually gave birth to a narrow view of human conflict occurs because not able to see from the higher side.
Including imposition of beliefs kepeda someone disagreed with him. In the end the opinion and the paradigm established by humanitarian factors are based on the interests will not liberate us from the confines of calamity and destruction of civilization. Only on integrity of the entire human outlook that will take us to the real view of all these events conditioned. However this view will not be tangible without any proper view of the concept of divinity in the end the truth whole and not only His and He's whoever will give it to anyone who tried to return to Him with ideas right. In this case apart from Kontoversi a verse in the Qur'an mebnyebutkan That these people who believe, Jews and Christians and people shabiin if they believe in God (back to the conception of the divine right), with good deeds in his life He will forgive them.I say sorry to all parties what if in my writing is not acceptable. Only to God I beg.

Next Generation Computer

The next generation of computers may make use of the "spin" of electrons instead of their charge.

Spintronics relies on manipulating these spins to make them capable of carrying data.

The technique has been shown in a number of materials at low temperatures before.

But researchers writing in Nature have made use of these "spin-polarised" electrons in silicon at room temperature for the first time.

The result could lead to computers that require far less power than conventional ones.

The fact that the effect has been demonstrated in silicon - the material that already underpins the computer industry - means that devices exploiting it could be made on a commercial scale more easily.

The problem with silicon is that, as the individual features on silicon chips get smaller and smaller, they require more and more power to move the charged electrons around to represent 0s and 1s of binary code.

That rise in power also means that future chips will run into problems with heating.

In a spin

Spintronics has long been touted as a future potential mechanism for computing, but so far advances have come slowly.

The idea rests on manipulating the "spins" of electrons, which can be either "up" or "down", a choice between two states that is analogous to the on/off or zero/one of conventional, digital electronics.

This "spin" isn't really a direction the electrons are spinning in, but rather a convenient way to express one of the two "quantum mechanical" states an electron might be found in.

A number of laboratory demonstrations has shown that it is possible to create bunches of electrons with their spins aligned and to detect those spins in a range of materials, most importantly silicon.

However, they have all been at extremely low temperatures.

Now, researchers at the University of Twente in the Netherlands have demonstrated the manipulation and detection of these spin-polarised electrons in silicon at a temperature some 150C warmer than the previous record.

"We've shown for the first time that this can be done at room temperature, which is obviously something you would need if you wanted to really commercialise this technology," said Ron Jansen, who led the research.

'First step'

The trick, Dr Jansen said, was careful design of the interface where the electrons enter the silicon - the materials must be pure and of a precisely determined thickness in order to preserve the delicate spin polarisation.

"Let's say it's the first real step towards a real working technology," Dr Jansen told BBC News.

"The next one is actually to build real electronic circuits and show that they are better than the electronic circuits that we have available right now."

Robert Hicken, a spintronics researcher at the University of Exeter, called the work "an important step in the development of spintronics technology".

"This tells us that one can now begin to look at room temperature, silicon-based electronic devices; the exact design of such a device we don't know yet, but this was a prerequisite for doing it."

What remains unclear, Professor Hicken told BBC News, is whether spintronics can overcome the problem of heating that conventional electronics faces as individual devices become ever more tiny.
