Fraunhofer Diffraction Means You Can’t See Properly

It’s depressing as you get older and your vision seems to get worse with every passing year.  But in reality the human vision is pretty poor anyway.  You might be able to see a passing ship on the horizon but you won’t be able to read the name on the side at any distance.  Our eyes have pretty useless resolution so images get blurred the further the distance you are.  Of course we can use binoculars to magnify an image but why can’t we see this stuff with the naked eye?

The reason is basically down to the size of our pupils also known as their apertures.  Our eyes need to be open wide enough to let through enough light to make sure that the sensors in the eyes start working.  However the more open the aperture is the more the light entering the pupil will blur.  The reason is that  all the light arriving into our eyes comes from a variety of directions, again the wider open the more directions the light will come from.

 

Most of the light waves come in parallel and form a bright clear central spot.  But the width of this ’clear spot’ is blurred at the edges by light waves arriving in different phases and hence cancelling each other out.  The result is that the edges have a series of light and dark alternating bands but looks very much blurred.    The width of the clear spot is actually what regulates the finest level of detail that our eyes are able to pick up.

Fraunhofer diffraction describes the blurred images that will be observed when the light rays arrive on a lens or aperture like the eye in parallel routes.  It is also known as Far-field diffraction and is easiest seen when we pass a light source from a long way away (perhaps the Sun) through a lens.  It doesn’t matter if the lens is in our eyes or a telescope the effect is the same.  The diffraction effect will also smear the final image for a camera, eye or telescope.  The limit of clarity is imposed when the light is passed through any sort of optical lens.  To learn more about science subjects like this, make a habit of watching the best science programmes.  I’d particularly recommend some of the superb ones being shown on the BBC recently, you can watch on the Iplayer.

If you’re outside the UK you’ll need to change your IP address to view the Iplayer – try this site for downloading from the BBC – http://www.iplayerabroad.com/2017/04/28/download-bbc-iplayer-videos-abroad/   It’s quite easy to do, routing your web connection through a British server takes minutes and gives you full access to all the wonderful BBC Iplayer programmes.

Academic Research and Web 2.0 Opportunities

Regular as clockwork, every year brings about a rite in Research Universities that is dreaded by certain Assistant Professors on the Tenure Track. Welcome to the Tenure Review process, a rite wanting to gain the ‘Holy Grail’ of tenure and the associated permanence at their universities of the employment contract. Originally conceived as a way of guaranteeing academic freedom, the advantages and disadvantages of the tenure system are endlessly debated by both academics and non-academics alike.

Regardless of one’s perspective of tenure, the critical success factor for the tenure process in most schools is research. Most universities aspiring to the more lofty strata of the rankings system put a massive emphasis on research-all kinds of research, whether funded or released.

A recent BusinessWeek interview with Drew Faust, President of Harvard University (Businessweek, 12/10/07) along with a follow-up public letter by several eleven public university provosts testify to the strength of emotions that research evokes in academia and also the competition which exists between universities. In 2006, over $47 billion was spent by universities on research and development (NSF, 2007), while competition for top journals was more extreme than before. If you want to access these reports, they are available to US readers free of charge or internationally by using a US proxy service like this.

In this competitive research climate and culture, there’s a marked contrast between high-flown research ideals and also the actions of research itself. Despite progress and computerization of the tools and increasingly advanced methodologies, there have not been comparable advances in the organization, reach, and range of research collaborations.

One would find his/her collaborations to be mainly local, upon scanning the curriculum vitae of a professor that is typical. Quite simply, most research professors compose grant proposals and articles with other professors who they already know. Included in these are graduate students and their colleagues down the hall, and previous co-workers or professors from their own doctoral program. Just in rare cases does the set of collaborators expand to incorporate other research workers they may have encountered at seminars.

Thus, when there is a researcher midway throughout the planet with strikingly similar research interests, regrettably, there is scant hope of the research professor ever actually working with her or him. Even if the initial researcher is not unaware of the other researcher through bibliographies, there is no simple ‘social’ means of connecting, short of directly e-mailing or calling. Of course, few professors initiate contact in this manner. Maybe they think the other researcher might not be amenable to work with them, or perhaps they need extra information about the researcher and getting this could be too boring. Most commonly therefore, it is only better to go with the ‘known’ quantities of reachable colleagues in what could be called “cooperation of benefit”.

So the obvious questions to ask are: can the action that is Web 2.0 toolset for academic research what are the tools that might facilitate this transformation? and what it’s done for social and business networking, Millions of previously unlikely business and social relationships and opportunities are created through such tools as Facebook and MySpace (social relationships), and LinkedIn and Ryze (business networking). Thus the question of the potential of Web 2.0 technologies is a useful one not only for universities looking to add to their arsenals in the research “arms race”.

What would a Web 2.0 portal look like? What tools might be on offer? What changes will be required in the mindset and practices of today’s academic research workers? Is there appearing tools in this class that may foretell the future for the actions of university research in the long run?

Web 2.0 portals for academic research workers must contain elements from the sphere of social networking. These would contain searchable professional profiles, newsgroups, and assorted way of communication, like instant messaging. Business networking tools might also contribute meaningfully through their approaches to contact management, referrals, and communication, to portals for research collaboration. In addition, while their knowledge taxonomies for classification of businesses and are somewhat rudimentary, these concepts may be useful in arranging the much more profound knowledge taxonomies crucial for the research communities. Maybe afterward, instead of collaborations of convenience, researchers might transition to global “cooperation of chance”.

While still inside their infancy, Web 2.0 research portal sites are sure to become important tools in the never-ending research “arms race” that characterizes research universities. They provide the advantages of collaborative international research – more extensive and better -fitting international collaborations, better-quality information for researchers, improved content for research papers and grants, and increased quantity of publications and grant proposals. Put simply, Web 2.0 tools could bring about a complete transformation of the practice of research and with it, major productivity gains.

Modern Web 2.0 research portals such as this enable researchers to collaborate on the site itself, handle actual documents and also network with co-workers and other potential research workers. It enables powerful web-based the categorization of results as well as searches into personal taxonomies.

The portal site uses their research interests and abilities as well as complete knowledge categorizations for categorizing users, which translates into having the ability to find research collaborators that are ideal with truth. It employs skilled article postings, sites, forums, advanced project management and news feeds of the latest research news. Moreover, it integrates specialized research tools that professors use most frequently, including survey creation/deployment tools, citation tools, bibliography direction and others.

These brand new web portals seem to point to the way. As traditional as the academic research culture may be, it appears unavoidable that universities will ultimately embrace the sea change brought about by the Web 2.0 paradigm. The challenge for Vice Presidents, and Deans, Provosts of Research is rapidly embrace these tools for the substantial increases they are able to bring to university research output and the best way to alter the research customs that is present. The entire world is flat and new synergies from international collaborations can’t be discounted. Certainly the early adopters will have the potential to advance their research rankings by investing in Web 2.0 toolsets for their research workers. In any event, the influence of Web 2.0 on academic research will be exciting to watch over the next several years.

Writing Killer Headlines Online

Which type of content is yours? Sales letters? Articles about how to do things? Blog post? The answer isn’t important-what’s important is that you need to come up with a good headline to make it work. Whatever you’re doing, a headline is probably the most important line of text mostly because it’s the most visible.

The reality is that many more people will read your headline than the rest of your content. It’s true, even video content has headlines from a simple YouTube video to streaming news from the BBC.

It’s true; if the headline you write is boring, so will your results be. When you want to get your content’s response rate up a level or two, it is important to put some work into honing your headline writing skills. And how do you make that happen? By reading this article! We’ll be discussing 3 effective tips to help you get results…

You should always identify your unique selling point before writing your headline. You don’t want to talk about something minor or irrelevant in your headline, but about the most valuable aspect of your offer or product. When you clearly state the benefit in your headline, your conversions shoot up. This is how you motivate people to keep reading. Readers don’t want to hear about your product in general, but only about what it will do for them. Headlines give you the opportunity to summarize this benefit in a few well chosen words. This will make your headline seem urgent to your prospects.

The more beneficial your offer looks, the better it is. Leverage the power of questions in your headlines. The only rule is that your question has to be something your audience will care about. You’ll find that questions are very effective at getting your readers interested. The idea is to make readers eager to know the answer to your question. We are naturally inclined to look for answers. Asking a relevant question, then, can be very effective. Remember that you have to avoid confusing your prospects. A good headline makes people curious, but it also informs them. Make your questions targeted and purposeful. Brief and clear questions are best. Curious readers are likely to have greater interest.

Is the headline you’ve created short and on target? If it isn’t, it may be helpful to shorten it. Use facts and make the minimum use of adjectives. Refer to the solution you’re offering, and that’s it. Give your readers something they can dig on. Don’t confuse them but rather give them value. Headlines are actually the most critical part of any sales copy. That’s why you have to put a lot of effort into them.

Content is the center of the Internet. Information is what matters most for content. And your headline is just the summary of all of that information. If you’re good at writing content, you should be good at creating headlines too. It is okay if you have failed before now. Failure is something everyone must accept but don’t let it keep you from practicing everything that you have learned. You need to take what you’ve learned here and put them to work.

It’s important to have headlines that will offer you the attention that you want and get you the response you deserve. The more you work on the attention part of your headlines, the better it is. Irresistible headlines are what you want to achieve. And that can only happen when you apply the basic foundation laying tactics in the best possible way.

The Real Divide of Digital Europe

One of the important areas that Europe is leading on is that of the digital market.  It’s an area that is of growing importance in all sorts of ways to the economies go European countries.  Literally millions of people use the internet to buy all sorts of things but also it provides employment to many thousands too.

The digital marketplace grows exponentially every year, yet outmoded rules, laws and regulations govern our transactions.  What’s more there is no real accepted standard, a digital transaction can easily encompass two or three countries – yet unfortunately this can also mean two or three sets of guidelines to follow. All is fine if a transaction is completed successfully but what happens in areas of dispute or digital fraud for example.

Take for example, the situation with digital services – you can purchase a subscription to say a Polish TV channel like TVN player and find as soon as you travel outside the borders of Poland you’ll lose all access to it.   In fact your subscription is completely useless unless you either return to Poland or invest in a Polski proxy to fool the channel about your location.   It’s a ridiculous situation, digital purchases are happening in the 21st century but are subject to 20th century restrictions.

Much of this is due to copyright problems however without a concerted legislative effort then it’s likely to continue.  The problem is that profit maximisation means that it is in the distributors best interest to license content on a geographical basis.  Why sell access globally when you can make the consumer pay for access for every country they happen to want access from.

A few decades ago this wouldn’t have affected very many people, but now travel is cheap and available. Many very ordinary people live and work across many national borders, some even have homes and lives in different countries.  Yet all the time these restrictive practices are being implemented in the digital market place.  It’s pretty much everywhere, take any country and you’ll find this same pattern of media problems. The popular channel in Italy, Rai Player can’t be viewed outside Italy, again unless you circumvent the restrictions like this video suggests – VPN Italy.  It makes buying anything digitally a huge risk, especially things like film and movie subscriptions for people who cross national borders.

It is hoped that the European Union can try and create a fairer digital marketplace although Brexit looks likely to have caused problems here.  THe UK economy is probably the most advanced digital market place in Europe and without it’s cooperation any solution is likely to be fairly piecemeal.

 

 

Missing the News Online

For many people, the news forms an important part of the day.  Whether it’s sports, politics, current affairs or simply gossip – human beings for the most enjoy hearing about the world around them.    It’s a part of our lives and in some ways creates our very own real-life soap opera which  develops every day.  The stories link together because they’re part of our shared society and sometimes greatly effect our own lives.

Which is why if  you move away from your home area and start watching the news in other areas it’s not quite the same. Even though you may have travelled to the new location, you watch the news with a slight sense of detachment simply because you have spent enough time in the area to belong.

When I used to travel a lot when I was younger in the 1980s, I used to spend ages searching for British newspapers.  This was no easy task, although it could be done in most places across the world.  Hotels were usually a good bet or shops in expats areas, you’d have little choice usually and the price would be marked up many times.  What’s worse the paper would often be a few days out of date depending on how remote the location, Europe was mostly ok for the day after.  Yet it was a link, to be able to stay connected to your ‘normal life’ at home while travelling.

Of course now it’s much easier, if you have access to the internet you don’t have that same sense of detachment. In fact you can pretty much live your life remotely in many senses, although it’s never a good idea to announce you’re travelling to much on social media.  People who do this often return to find their home has been burgled!  Yet you can keep up with all sorts of gossip and local news fairly easily with a laptop or tablet.

There is a drawback though, although most News and media companies stream their broadcasts online mostly they are inaccessible from other countries.  It’s not a technical restriction but a restriction imposed by the broadcaster to prevent people watching abroad.  For example watching the BBC news online is actually quite difficult outside the UK because it is blocked by the BBC.

There is a solution you need to use VPN or proxy servers to try and hide  your real physical location.  This works by obscuring your real IP address and presenting the VPN servers address instead.  If the address happens to be linked to right country then you should be able to access the site as normal.
