The Say of the Week February 14, 2008

Posted by dorigo in Blogroll, computers, physics, science.

Rather than assuming quantum behavior as a nuisance to shield from, we have to accept it as an intrinsic and powerful element of reality, and learn to exploit it in our designs. Once we do that, everything in engineering is going to change radically: from design, to construction, to building, to project management.”

David Orban

seriously now. either Orban was quoted WAY OF CONTEXT or else he was bullshitting (sparando cazzate).

2. dorigo - February 14, 2008

Goffredo, of course it is a quote out of context – it is just a quote, with no commentary! In any case, he was talking of engineering in the next 100 years.


3. DB - February 14, 2008

He’s not saying anything new anyway. Dick Feynman said it almost fifty years ago, and somewhat better:
“Atoms on a small scale behave like nothing on a large scale, for they satisfy the laws of quantum mechanics. So, as we go down and fiddle around with the atoms down there, we are working with different laws, and we can expect to do different things. We can manufacture in different ways. We can use, not just circuits, but some system involving the quantized energy levels, or the interactions of quantized spins, etc.”

The complete text of Feynman’s speech is here:

I agree DB, and am aware of Feynman’s vision on nanotechnology. However, I liked the sentence for its simplicity.


5. David Orban - February 14, 2008

Goffredo, the latest chip designs are already leaning in the engineering direction that I describe (and, DB, Feynman of course, and it is a great honor to be in the same post with him!). Intel, AMD, and others just can’t keep their pace of innovation by pushing *against* the quantum tunneling effects that complicate their designs at the smaller scales. Reversible circuits, 3d circuits, spintronics are all going towards that, too.

Much of what we learn through advancing our technologies for computer science, is going to percolate through, and impact other sub-fields of engineering as well…

Once we do that, everything in engineering is going to change radically: from design, to construction, to building, to project management.”

Design of what?
Building of what?
Construction of what?
Project Management of what? is going to change radically????

Some things will change radically, others somewhat, and others very little. E.g., I’m very skeptical that Project Management will change radically because the quantum nature of things makes it into engineering design.

8. Arun - February 16, 2008

I’m using the Wiki definition of Project Management here, and I challenge anyone to show me how quantum physics is going to change project management radically:

“Project management is the discipline of organizing and managing resources (e.g. people) in a way that the project is completed within defined scope, quality, time and cost constraints.”

9. dorigo - February 16, 2008

Well Arun, we are talking of 100 years ahead here. I can well imagine human beings enhanced by quantum computing devices, who interact with a computing project in a way we can only find in science fiction novels today. Like, plugging in to it.

I am not asking you to buy this, but this, at least, is what our futuristic Kurzweil’s singularites think is going to happen.
