A Model for Science

Science is growing more complex, and so are the problems scientists face. A growing number of researchers argue that changing not just how we do science, but how we share it as well, would unlock vast new opportunities. A recent conference at Perimeter Institute asked: Is the time right for open source science? See:Can open-source software be a model for science?

Estonian Li-Fi

The Reference Frame: Estonian Li-Fi: Tens of GB per second using light bulbs Velmenni, an Estonian startup , has tested the visible light-based replacement for Wi-Fi in the re...
Article by Lubos is an extension of information contained herein this blog regarding Lifi. SeeHarald Haas

Li-Fi (Light Fidelity) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. Coined by Prof. Harald Haas,[1] Li-Fi is a subset of optical wireless communications (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting. It is so far measured to be about 100 times faster than Wi-Fi, reaching speeds of 224 gigabits per second.[2]
It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.[3] A complete solution includes an industry led standardization process.

Lifi and 5g: Optical Communications

Visible light is only a small portion of the electromagnetic spectrum.

I have been away a while getting caught up on some work and enjoying some vacation time. I am always exciting about where we are going next in terms of communication development. Some of these previews  have been show here in various blog posts, that you can preview with label access.

The United States 700 MHz FCC wireless spectrum auction was started by the FCC on January 24, 2008 for the rights to operate the 700 MHz frequency band in the United States. The details of process were the subject of debate between several telecommunications companies, including Verizon Wireless, AT&T, and startup Frontline Wireless, as well as the Internet company Google. Much of the debate swirled around the "open access" requirements set down by the Second Report and Order released by the FCC determining the process and rules for the auction. All bidding must be commenced by January 28 by law. The auction was named Auction 73.[1]

The interesting thing here in terms of development is that the industry is still in a sort of infancy where those who are quite brave in terms of their science and knowledge back ground can contribute and create a different type of communication base that is current residing outside of government regulations right now. The spectrum allocation is currently not licensed and using that platform if you can develop it create the possibility of networks that do not currently reside in spectrum allocation that are being sold.?

Li-Fi, or "light fidelity", is a technology, that can be a complement of RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting. Li-Fi, like Wi-Fi, is the high speed, bidirectional and fully networked subset of visible light communications (VLC). It is wireless and uses visible light communication (instead of radio frequency waves), which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.[1]

 While we know the ground rules of communication are limited in terms of wifi, the future is quite as to how information can be disseminated and how much of it can be accessed through new technology that will reside outside of the devices that currently are being adapted too, to use that type of communication. So I encourage new development here if you have the brains and brawn in order to tackle that new fledgling business of the future.

 It is a 5G[2] visible light communication system that uses light from light-emitting diodes (LEDs) as a medium to deliver networked, mobile, high-speed communication in a similar manner as Wi-Fi.[3] Li-Fi could lead to the Internet of Things, which is everything electronic being connected to the internet, with the LED lights on the electronics being used as Li-Fi internet access points.[4] The Li-Fi market is projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 billion per year by 2018.[5]

It is a sobering thought to thing of the optical side of things of having such a wide market growth, with the potential of money development, but at the same time brings to light the development that is currently and has yet to become marketable through innovation and technological design. So I encourage the young folk coming out of universities to explore at least from their educative perspective and expertise this area of communication and technological design..

pureLiFi is at the forefront of research and commercialisation into Li-Fi, an industry expected to grow from $100 million to $6 billion by 2018. Visible Light Communication (VLC) is the use of light to transmit data wirelessly. Li-Fi - a term coined by pureLiFi’s Chief Science Officer and co-founder, Professor Haas – is a technology based on VLC that provides full networking capabilities similar to Wi-Fi, but with significantly greater spatial reuse of bandwidth.

OPALS is manifested to launch on the third ISS resupply mission by a SpaceX Falcon 9 Dragon in February 2014.
This artist's concept shows how the Optical Payload for Lasercomm Science (OPALS) laser will beam data to Earth from the International Space Station. Credit: NASA. 
"OPALS represents a tangible stepping stone for laser communications, and the International Space Station is a great platform for an experiment like this," said Michael Kokorowski, OPALS project manager at JPL. "Future operational laser communication systems will have the ability to transmit more data from spacecraft down to the ground than they currently do, mitigating a significant bottleneck for scientific investigations and commercial ventures." SEE: NASA's OPALS to Beam Data From Space Via Laser

OPALS will be mounted externally on the International Space Station (ISS) in a nadir position on an ExPrESS Logistics Carrier (ELC). Image is credited to NASA/JPL-Caltech.

 The fastest commercial communication links on Earth use optical (or laser) fiber to transmit information. Using laser in space without this fiber is another method.  Fast laser communications between Earth and spacecraft like the International Space Station or the Mars rover Curiosity could enhance their connection to the public.  OPALS is also used to educate and train NASA personnel.

The Internet

What is the Future of the Internet

I plug into the electrical plugin and receive all my information stored on the information grid.

There is evolving aspect with which communication is being used, bought and directed as to how this information is contained? How Governments seek to control? How Companies would value our access too?

So this is a another question for others as well to consider this future. Maye you have an opinion. Maybe there are people involved in helping to constraint government with full control?

White Space Sensor Development

 To manage the White Spaces is a way to improve process performance of an organization(internet). White Space (management)
 The idea has always been to operate within certain frequencies in order to develop the communications needed for rural development. Sometimes,  in context of management we see where governments needed to manage these frequencies in order to be able to auction off facets of those frequencies. This is to ensure companies are safe from other developers who may damages their operations,  as well as give companies what they paid for.

 On September 23, 2010 the FCC released a Memorandum Opinion and Order that determined the final rules for the use of white space for unlicensed wireless devices.[18] The new rules removed mandatory sensing requirements which greatly facilitates the use of the spectrum with geolocation based channel allocation. The final rules adopt a proposal from the White Spaces Coalition[19] for very strict emission rules that prevent the direct use of IEEE 802.11 (Wi-Fi) in a single channel effectively making the new spectrum unusable for Wi-Fi technologies... See: FCC decision

So of course such developments need to consider the techniques used for sensors so as to be able to operate between all these frequencies.This then require services as a means to providing broadband capabilities via White Space spectrum.

White space in telecommunications refers to unused frequencies in the radio waves portion of the electromagnetic spectrum.

The latest information of Google attempts at developing communication development in Africa is of course a long road to White Space communication.

White spaces are unused channels in the broadcast TV spectrum. They offer the potential to improve Internet connectivity where they are most needed - in the developing world. Today we’re announcing the launch of a trial with ten schools in the Cape Town area, which will receive wireless broadband over a white space network.

White space has the advantage that low frequency signals can travel longer distances. The technology is well suited to provide low cost connectivity to rural communities with poor telecommunications infrastructure, and for expanding coverage of wireless broadband in densely populated urban areas. See:
Announcing a new TV White Spaces trial in South Africa

There has been some developments in terms of management with the rules and regulations with regard to that White Space development within the US, UK and Canada. This has more to do with regulations about controlling the impingement of frequencies on existing companies already using frequency white space. To ensure that any use of that White Space does not cause any disruptions with require certifications of a sort,  to demonstrate that this is such the case.


I am exploring some ideas here on community development. This is so as to developed further communication formats.  These broadcast systems,  need to meet the demands of rural country deployments frequencies between tower locations,  as well as,  development of those community based broadcast system.

 While I have watch the proceeds of government working with major internet company to develop this process.  I am less then happy with the outcome of Tax dollars that have been spent to progress this development in rural country living not only Provincially, but Federally as well. IN a Federal sense there has been no accountability with this progress and money granted.

While watching Google history here, and latest development in Africa it seems it has gone far away from its home base to develop the framework. I sometimes wonder then if the community in the framework of governments is some how caused such a innovative process as a the result of that development in Africa? Of course that is speculation on my part and any success on this front pushes forward the desires of what communication can reach the far ends of the earth and bring global communication to the nourishment of every individual on this planet.

The Black Hole of What?

In networking, black holes refer to places in the network where incoming traffic is silently discarded (or "dropped"), without informing the source that the data did not reach its intended recipient.

When examining the topology of the network, the black holes themselves are invisible, and can only be detected by monitoring the lost traffic; hence the name.


Dead addresses

The most common form of black hole is simply an IP address that specifies a host machine that is not running or an address to which no host has been assigned.
Even though TCP/IP provides means of communicating the delivery failure back to the sender via ICMP, traffic destined for such addresses is often just dropped.
Note that a dead address will be undetectable only to protocols that are both connectionless and unreliable (e.g., UDP). Connection-oriented or reliable protocols (TCP, RUDP) will either fail to connect to a dead address or will fail to receive expected acknowledgements.

Firewalls and "stealth" ports

Most firewalls can be configured to silently discard packets addressed to forbidden hosts or ports, resulting in small or large "black holes" in the network.

Black hole filtering

Black hole filtering refers specifically to dropping packets at the routing level, usually using a routing protocol to implement the filtering on several routers at once, often dynamically to respond quickly to distributed denial-of-service attacks.

PMTUD black holes

Some firewalls incorrectly discard all ICMP packets, including the ones needed for Path MTU discovery to work correctly. This causes TCP connections from/to/through hosts with a lower MTU to hang.

Black hole e-mail addresses

A black hole e-mail address is an e-mail address which is valid (messages sent to it will not generate errors), but to which all messages sent are automatically deleted, and never stored or seen by humans. These addresses are often used as return addresses for automated e-mails.

Mega Mind?

Source:Numerical Relativity Code and Machine Timeline

In 2005 in "Lightening," as Strings, Strike?" I could see where certain issues were developing in terms of using computerized techniques in order establish a numerical correlations. Computations with how one might look and see the universe. Albeit, the brain in the end always came to my mind too.

DEUS consortium is developping the largest cosmological Dark Matter simulations to date with realistic Dark Energy component, involving billions of particules, with highest spatial resolution for the largest set of simulated Universe. Our challenge is to reproduce with unprecedented details the cosmic structure formation process and answer to the fundamental questions: what can we learn on Dark Energy from Large Scale Structure Formation (LSS) ? and How LSS formation process is affected by the presence of Dark Energy ? and then to understand the nature of the Dark Energy., Contact:

UK intelligence to monitor electronic communications

But Britain's home office interior ministry said ministers were preparing to legislate "as soon as parliamentary time allows", saying it would be data, not content, that would be monitored. "It is vital that police and security services are able to obtain communications data in certain circumstances to investigate serious crime and terrorism and to protect the public," a spokesman said.UK intelligence to monitor electronic communications
The Uk in terms of communications security is coming late to the party?

“We are proposing measures to bring our laws into the 21st century and to provide the police with the lawful tools that they need,” Mr. Toews said to the MP for Lac-Saint-Louis, Quebec. “He can either stand with us or with the child pornographers.”

Selectively one may of held this surveillance as to some kind of thing Iran or China scheme is doing, when, it has already happening within Canada. If electronic media is to be incorporated into free societies then the misnomer is, we are no longer free?
Big Media lobbyists are trying to lock down the Internet in Canada through legislation like Bill C-11 and the trade agreements ACTA1 and TPP2. Bill C-11 has already passed its second reading. It currently includes provisions to lock users out of their own services3 and give Big Media giants increased power to shut down websites have already made their way into Bill C-11. See:Dear Parliament: Say no to the Internet Lockdown
Who is watching the police and the security forces? I'm just saying. How can we allow the freedoms when we are restrictively applying that freedom? I am definitely open to what people have to say about this. What governments have to say about it. Who is in control of Governments...The People?

Thoughts on the Filter Bubble

 What got me thinking. This was part of a  comment to a post I read this morning. This was the catalyst for it's construction. I do not think I supply any answers but just make one more aware of their surroundings.

Matt:"It would appear, from the above comments, that almost the only people willing to comment on this topic are those who agree with me to a greater or lesser extent. Which might also mean that the only people reading this blog are those who agree with me. That is quite disappointing, but perhaps not entirely surprising in this deeply fragmented era."

I am not quite sure what you are after. You yourself are a product of the internet?:) Thoughts on the Filter Bubble -

While I cannot be specific as to why there are not more responses from those regarding your article here,  the chart "upworthy- " has established and demonstrates as you can see that maybe your article is 0.1% of interest to some people?

So your response while focused here on this question of yours holds thoughts about the "deeply fragmented era." It is an informational world and quite vast. Scientists operate as only 3% of the population so while specific to the population only a portion of that population as a small amount might be interested?

Some of us who are looking to discover the deepest secrets about our capabilities as human beings are now exposed to the technology that places us in packages for  inspection. Algorithmically design computer processes that track our progress?  No,  you are not being paranoid.

Individualistic as we are in our pursuit maybe we should start a blog or something to specifically detail the areas of interest that we are after?  Then people will choose.

We can't change all that. But we believe the things that matter in the world don't have to be boring and guilt-inducing. And the addictive stuff we love doesn't have to be completely substanceless. Our core message is: See: Upworthy
So how do you filter out stuff that only you want in regards to that 0.1% of stuff that actually matters to you? No not what somebody else chooses for you, but research that is specific to what you are after.

Some of us care about science and the current issues being put out their today and how much is it of a journalistic fervor for all the trappings that make up the internet. For sure, the wide world of the electronic media is a new place for business. A place for disseminating information about our governments and the political ideological ideals. Sharing?

Every year, thousands of entrepreneurs, change-makers, innovators and scientists gather in Long Beach, California for TED, the world’s leading thought conference. In 2011, the audience included executives from Facebook, Google, Microsoft, Yahoo, and many other Silicon Valley startups. So when Eli Pariser explained the filter bubble concept and then called on them from the main stage to change how they do business, it wasn’t at all clear how they’d react. Watch the video to see what happened:See:The Filter Bubble

 From an earlier posting and a repeat here about what rights we have have been undermined by governments as to our privacy? So the question is, how long before DuckDuckGo disappears?

Flattening the World: Building a Global Knowledge Society

The focus of the 2012 meeting, then, is on using the power of electronic communications and information resources to tackle the complex problems of the 21st century on a global scale through international, multidisciplinary efforts. We have a model already in the scale and scope of the Intergovernmental Panel on Climate Change (IPCC). But that’s just the beginning. The interconnections among, for example, climate change, agriculture, and health are as yet poorly understood; predictive modeling is in its infancy.
The ability to approach global problems through global collaborations depends on an educated populace and on substantial scientific and technological sophistication throughout the world. Thus building the global knowledge society depends on advancing education and research, the engines of the knowledge society, everywhere. This task is facilitated, but not accomplished, by the existence of electronically accessible open educational resources. There remain limitations of language and culture, of poverty and access.See: Flattening the World: Building a Global Knowledge Society(bold added by me for emphasis)

Flattening the world sounds like something that you would not like to return in thinking about the push for society to become better informed and pulled out of the dark ages? But it's not really about that. It's about leveling the playing field in terms of,  "Globalization of Knowledge."

 WIRED: What do you mean the world is flat?
Thomas Lauren Friedman

FRIEDMAN: I was in India interviewing Nandan Nilekani at Infosys. And he said to me, "Tom, the playing field is being leveled." Indians and Chinese were going to compete for work like never before, and Americans weren't ready. I kept chewing over that phrase - the playing field is being leveled - and then it hit me: Holy mackerel, the world is becoming flat. Several technological and political forces have converged, and that has produced a global, Web-enabled playing field that allows for multiple forms of collaboration without regard to geography or distance - or soon, even language. See: Why the World Is Flat

The theme above then in opening linked article is like a mission statement.  So in a sense,  I highlight with the paragraphs above to illustrate what a stubborn scientist frustrated has been like,  locked in his own perspective about climate change( it seems a formulation principle arises with the basis of that topic. Okay, the presentation is specific and he talks about Quantum Computing) That one might in his case may cast a wide sweeping statement about the aims and purposes of giving as much knowledge as possible to the masses, as being leftist.

 Right,  left?  Nothing like being stereotype, yet,  a question in my mind exists about globalization? Suffering from "the products"  from which one could have grown up,  you can understand indeed why such skepticism might be measured as a "dying voice of concern about that global village?"  This though,  is not about economics. You See?:)

The public, needs to be better informed. Remove the barriers and constraints to that knowledge you then are successful in raising the standards of communication across the world. It should lower the stress level for an  impatient scientist who is frustrated with the level of knowledge perceived from the basis of the questions asked by the public?:)

 Ask you self then.........In respect of knowledge, do those who control the medium, control the message?

 The very thing you might fight for is in fact a form of something that one might see as being repressed under a presentation of some communistic system,  when in fact,  such monopolistic controls are much the same?


So why have I stayed out of the climate debate change? One, because I do not know enough, and two, because I knew nature was ever present while we were contributing to the environment in which we live.

So the population,  since my looking into the subject of particle research has it's basis set in understanding our connectives to the space around us? What is happening in the airs above earth that you would not take notice? Cosmic particle research? It may help one understand the logo better? Like ideas,  particles exist all around us?:)

How does this then contribute to the understanding that nature is ever a greater force then humanity could ever think itself  as to the design of our place in history.

Control the Medium, You Control the Product?

The historical record, as I’ve also argued, is also quite unequivocal on the folly of allowing those who own the medium to control the message See: The Vertical Integration Elephant in the Room
 For differing points of view some might have a take on the process unfolding in our society today as a sign of the way things have always gone? Do you feel the same?

A Thomas Nast cartoon shortly after the Supreme Court affirmed Alexander Graham Bell's patents (library of congress)


At least seven major cities adopted measured service in the 1880s: Boston; San Francisco; Buffalo; Pittsburgh; Indianapolis; Washington, DC; and Rochester, New York. The policy had a pro-consumer aspect; it expanded the market of any local exchange carrier to people who didn't want to pay a big monthly service fee, thus extending the circle of individuals any rate payer could call.
But while measured service initially succeeded in San Francisco and Buffalo, it failed everywhere else throughout the decade. Consumers could not shake the suspicion that its real purpose was to get them to pay more money to the telephone company. And so they resorted to what we would call boycotts and they called "strikes" to make their dissatisfaction known.

"The term 'strike' has come to be associated primarily with a work stoppage," John notes, but "in the 1880s its meaning was broader. A corporation could be struck not only by workers, but also by consumers and even lawmakers."

As early as 1881, for example, Washington, DC's "Telephone Subscribers Protective Association" launched a boycott of its exchange when the company adopted measured billing. It wasn't very long affair, just twelve days. But 300 out of the city's 700 phone subscribers participated. That was all it took for the firm to surrender and bring back flat rates. See: Mad about metered billing? They were in 1886, too
