Quantum Thoughts

Recently Zurek, a well know physicist, famous about his out of the box approaches, published a paper on natural selection based on quantum computation principles. It’s main claim is that it explains the quantum-classical transition: why macroscopic physics obeys classical rules while the quantum world obeys the seemingly weird laws of quantum mechanics. That makes it a Big Idea.

So how does it work? Zurek’s way into this problem is to think about
the role of the environment in quantum mechanics. For other quantum
physicists, the environment has never been anything more than a
nuisance. Consider a quantum object in isolation and the quantum
information it contains can survive forever. But place it in the real
world and this quantum information leaks into the environment,
destroying the system under study.

Zurek takes different view. He thinks of the environment as an
information channel and the properties of this channel are the key to
understanding quantum Darwinism.

All macroscopic measuring machines get their information through
this channel. For example, at this very moment you are intercepting a
fraction of the photons emitted by a screen. But we can never observe
all of the environment, only a small fraction of it which reveal
systems of interest.

This is the essence of quantum Darwinism, says Zurek. Only quantum
states that can be transmitted through the environment in the right
kind of way and with multiple copies, can be observed on the
macroscopic scale. That rules out various kinds of quantum information.
What’s left are what Zurek calls “pointer states”. These are what we
observe classically.

This complies with Campbell’s approach on non linear natural selection. All these quantum computational aspects will proportionally start to affect many areas of your modern understanding of nature. Do not forget that nature’s game of play is laws of physics and in the microscopic world or in thermal noise free environments nature is actually a quantum computer and state superposition can easily result to exponential large calculation with just a single gate level step!! Other studies about quantum brain and neuron microtubes, are rather bulk approaches since they do not take into account the brains thermal background. Environment is a noisy quantum channel with infinite degrees of freedom and strongly non diagonal density matrix, so often destroys quantum nature by simulating measurement operators and collapsing the wave-function! Nevertheless though, we are just now starting to understand how quantum information can be preserved even in noisy channels, knowledge that can dramatically change the way we understand both nature and ourselves.

Apple Desktop iMac MB952GR/AI see that the new iMac is available in Plaisio. So just 5 or 6 clicks away. I will thing it over the weekend and order it at Monday 😉

A very interesting implementation (unfortunately in flash ;-)) that uses gecoding for the postal code address lookup and street view API for home front reading. Lets you decorate with Christmas ornaments your house exterior, a very common habit in the United States and Northern Europe. This is my attempt, not so successful I have to admit.

eIQimageOK most of you are aware that I am in the proposal writing industry (yiap, innovation and project writing defines a multibillion industry) and I ahve to admit there is no tool as inspiring as google RSS reader. My feeds span all the ne and emerging technology fields, so I digest more that 2000 feeds per day on many interdisciplinary areas. The inspiration mechanism works as follows in a rather GTD compliant way I might add, each good and possible product-creation idea I find, I share and star with the appropriate tagging for easily retrieval. Some times I send it immediately to friends and colleagues more relevant to the subject or that I know they are on something similar at that time. Ideas also are parsed from my rss and taxonomized in a managed news drupal installation, facilitating all nice features feeds API provides. Therefore when a new call is launched the only thing I have to do is feed my neurons with quality input and let synapses fire their best to come up with something innovative at the edge of scientific research both applied and principal. Cool documented and repeatable process that always has results. In addition, always ask why and always book some time for brainstorming with colleagues since this is when real thing are getting done in the idea formation perspective.

My motivation to write all these things down was an idea we came up for an energy governance home device that attaches on your household’s electrical board inspired from here, provided and implemented from eiqenergy.

Some ie6 bug prevent from properly clearing the options of a select html element. This is an issue the actual length that myselect.options.length statement returns. The smart way to do this is with a while loop.

            function removeSelects(elementId){
                var myselect = document.getElementById(elementId);
                for(var i=0; i<myselect.options.length; i++){
                    myselect.options[i] = null;
                while (myselect.options.length > 0) {
                    myselect.options[0] = null;


Multitasking was warhiped in the

Multitaskers are suckers for irrelevancy. Everything distracts them.

The irony is that even this partivcualr blog post is a product of multitasking in the irrelevancy playground.

Sometimes a universal conjunction happens and you appear to be in the middle. Yesterday my S3Fox FF pluggin was denying me the privilege to create a bucket located in Amazon‘s Europe datacenter. Seemed to be a mallformed encoding issue on the url post of my secter key from the client. I figured what the hell, different server locations different locals or somenhting and blamed Amazon. Apparently, though this was ridiculous,  took me much to figure out. Story goes as follows, after 30 minutes of coping with the problem I did a firefox restart due to memory being up to 1GB. Right after ff restart, I saw an S3Fox update that completely solved the problem. Astonishing how this coincidence worked out things. I wonder when will be the time where software will be build automatically and bugs will also treated by robots “in client presence”. Now that I reconsider it though, there will be no more bugs on software, but only features so proving truth to the old IT saying about bugs and features.

Configure your Drupal blog to use blogging firefox pluggin Scribefile.

  1. You need administrator priviledges since you have to activate Blog and Blog API if you have not done so.
  2. Go to Administration Site building Modules
  3. Enable the Blog API module and if you like writing composing Blog posts also from your Drupal web pages enable also BLog module.
  4. Go to Administration Site configuration Blog APIs
  5. Check at least one content type that is considered a blog entry (typically story, blog entry) and press save.
  6. User management Permissions blogapi module
  7. Ensure the user group (authenticated user or the group user belongs) is checked for “administer content with blog api”. save.
  8. UPDATE: If you like to post videos and images directly from your Scribefire account using the blog API, you shoulb make Full HTML input the default input setting for your site. To do so go to Site  configuration › Input Format tab and choose Full HTML as the default input type.
  9. Open  ScribeFire and click on the add account wizard in the right side of the ScribeFire window.
  10. In the Wizard: click “Manually Configure”, select “Custom Blog”,click “Next”, select “Drupal” blog system type, type in your domain. Enter domain name as(http://mysite.com/xmlrpc.php), click “Next”, enter your username, password, click “Next”, click “Done”.
  11. That’s it you now can write post using your firefox pluggin and integrate them seamlessly to your blog.

In future article we will also cover the procedure on how to automatically blog on Google Readerliked or shared items using grasemonkey scripts.

The way terahertz waves are absorbed and emitted is often used to determine the chemical composition of a material. the have a small skin depth so they don’t travel far inside the body, but lately they are often used breast tumours spotting as well as non invasive inspections.

Moreover, terahertz photons are not energetic enough to break chemical bonds or ionise atoms or molecules, the chief reasons why higher energy photons such as x-rays and UV rays are so bad for us. But could there be another mechanism at work?

Technology review says that

The evidence that terahertz radiation damages biological systems is mixed. “Some studies reported significant genetic damage while others, although similar, showed none,” say Boian Alexandrov at the Center for Nonlinear Studies at Los Alamos National Laboratory in New Mexico and a few buddies. Now these guys think they know why.

Alexandrov and co have created a model to investigate how THz fields interact with double-stranded DNA and what they’ve found is remarkable. They say that although the forces generated are tiny, resonant effects allow THz waves to unzip double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication. That’s a jaw dropping conclusion.

And it also explains why the evidence has been so hard to garner. Ordinary resonant effects are not powerful enough to do do this kind of damage but nonlinear resonances can. These nonlinear instabilities are much less likely to form which explains why the character of THz genotoxic
effects are probabilistic rather than deterministic, say the team.

This should set the cat among the pigeons. Of course, terahertz waves are a natural part of environment, just like visible and infrared light. But a new generation of cameras are set to appear that not only record terahertz waves but also bombard us with them. And if our exposure is set to increase, the question that urgently needs answering is what level of terahertz exposure is safe.

I discovered a service in Capirtal.gr, one of the most emerging Greek information portals, that provides real time stock prices in smart mobile html area. The page is plain html/js so viewable by most browsers. The only pitfall is that to refresh your results you need to do it manually clicking on the refresh button.  Check it your here.

One cool and one line js modification would be when all result table finishes to issue an automatic page refresh.

Since you have the data you people there in Capital.gr it will only take use a weekend here in Niobium Labs to make a cool Android and iPhone client you could distribute, with adds on top. This is actually a screen shot from my android browser.
