Before I first visited there for the first time, I knew little enough about Valencia. Sure as a keen European football fan I knew they had a decent football team, and that my oranges were often grown there but that was pretty much about it. However over the years as my travel horizons have broadened and moved from the tourist hotspots in Spain and Barcelona I’ve realized what a beautiful place it is too visit.
The Orange Blossom Coast …
The coastal Mediterranean region of Valencia is home to fragrant orange, lemon and peach groves, to the over-developed Costa Blanca and the attractive old resort towns of Javea, Altea and Alicante.
Lively, warm and welcoming, Valencia City is Spain’s third-largest city and birthplace of its most famous dish – paella. Refreshingly non-touristy, it is blessed with beautiful weather, an excellent fine arts museum, and an atmospheric old town. Valencia’s cathedral reflects the city’s rich architectural history with Gothic, Baroque and Renaissance styles all featured. It is claimed that the Holy Grail (Santo Caliz) – the gold cup used by Christ during the Last Supper – is housed in the cathedral’s museum. There’s been some fantastic art and history programmes on British TV that have covered these subjects which should be available online. You can’t normally access the BBC from Spain but this post can help you bypass those blocks.
The orange blossom coast – Costa del Azahar – stretches north from Valencia city. With a rich hinterland dominated by spectacular displays of orange blossom every spring, it is also home to the historic Roman town of Sagunto and the attractive resort of Benicasm. Sagunto, lying 25 kilometres north of Valencia, is made up of three parts – the Roman ruins and old town, the modern new town and the resort of Puerto Sagunto on the coast.
Explore the Roman theatre and castle and then head for a refreshing swim off the town’s sandy beaches. Journey on to the university town of Castellon de la Plana which boasts an excellent fine arts museum and interesting modernista architecture. Heading inland, the enchanting towns of Morella and Mirambel in the north and Jativa in the south are well worth visiting. Relics – including a Neanderthal skull – have been found dating to 30,000 BC in a cave near Jativa.
Valencia’s Costa Blanca – White Coast – is one of Europe’s most visited regions and can be very crowded in summer. The towns of Altea and Javia boast interesting old quarters and Alicante is a charming place. Stroll along the white sandy beaches and visit the 16th century Castillo de Santa Barbara which overlooks the town. Sample some tapas and seafood in the restaurants of El Barrio – the old part of town.
Additional: The use of VPNs and proxies are well established for bypassing geo-restrictions imposed by many websites. Using one makes your current location irrelevant and allows you to watch the BBC in any country in the world. It could be Spain, Italy or even South Africa it doesn’t matter as long as the target server is in the right location. Choosing the right service can be tricky but there are a few reliable companies – you can read one here which has lots of UK but also Italian servers too.
Netflix is probably one of the world’s first truly global internet entertainment companies. Of course, there are lots of entertainment companies who operate internationally there’s few that can boast a truly global reach. If you try and access many entertainment companies and streaming sites from certain countries you’ll simply get redirected or blocked. Companies like the BBC are only properly accessible from the UK, most of the US media sites only work fully in the US and so on.
Netflix used to be like this, if you traveled outside it’s coverage areas then you couldn’t get access. However around two years ago Netflix extended it’s reach to an extra 170 or countries and effectively to pretty much everywhere in the world. What’s more your Netflix account will work with any of them, so if you subscribe in Europe and travel to Mexico you’ll still have access to the site.
It’s not quite that straight forward though, because when you travel to somewhere new then your Netflix account changes too. Depending on where you live this can be extremely frustrating as many versions of Netflix are simply not as good as others. If you’re half way through some new box set in the US version of Netflix and you travel across to South America there’s a very good chance that show will disappear. The reason is that most of Netflix show’s at least all the ones not produced by them have to be licensed on a per country basis. Which means that they spend different amounts depending on the market, the Belgium version of Netflix is never going to be as profitable as the US version of Netflix simply due to relative size.
This video explains –
As you can it’s actually quite simple to switch from one version of Netflix to another. You don’t need to be locked into the version that your physical location determines. Which means that anyone can access the best version – the US one, or if you prefer to access another you can do that to. It should be noted though that most of the VPN companies like the one demonstrated in the video will only support US version of Netflix. It can be very difficult to find a way to access the Japanese one for example – without travelling to Japan of course.
Hopefully this will change in the coming years, it’s rather frustrating that the version you get is simply dependent on where you are. Especially as Netflix charges pretty much the same in subscription costs wherever you happen to be. There’s more information in this post here about how to unblock US Netflix in 2018 using the different methods of changing and hiding your IP address.
Thanks to the internet, the world is now full of people who make their living online. Now I’m not just talking about those annoying YouTube characters who seem to earn millions for doing nothing very much. For every high profile celebrity, there are literally thousands of people running small websites, drop shipping businesses and even blogs on all sorts of subjects. Many of these are using the internet to replace a traditional income and run their small businesses from home.
It’s often surprising to those who just use the web for entertainment or ordinary tasks that so many people have discovered a way to finance their lives. Yet for those of us who do make the majority of their income online – it’s actually incredibly common. It’s something that obviously appeals to many people, especially if you look at how many people search for terms like ‘ make money online’ or ‘earn money from blogging’. You’ll also find many thousands of pages showing you how to do this or even to become rich online.
The reality is that although a few do become very rich from the internet, the majority just make a living. Running things like stores on eBay can potentially make you rich but it’s actually very hard work and most simply earn a normal income. The ones who succeed in that environment have often invested huge amounts anyway in infrastructure, stock and people just like a normal physical business.
What does often surprise people is the sheer variety of money making possibilities online. Money making ideas that seem far fetched often become reality online for a variety of reasons including the following:
All these suggest that making money online is easy, of course it isn’t and many more people fail than succeed. However it’s certainly possible and every day more and more people are switching online with all the advantages it brings. For example I spoke to young man who makes all his money buying and selling sports shoes online recently. All he does is use a series of computer programs and these ATC proxies as described here, to buy limited release sneakers and resell them on eBay. This simple concept earns him a six figure sum every year with limited time requirements.
It’s a slightly technical thing to do, but there are actually books and guides explaining what you can do online anyway. Some might find it a little unethical but there’s nothing actually illegals going on merely using technology to buy up stock and resell it. It’s an example of how a trivial little method can be scaled up to produce a huge income online. All you need it a home computer, a credit card and the knowledge to implement a plan to be successful.
The way our lives are migrating online the opportunities for making money on the web will only grow. It is hoped that in developing countries in places like Africa the internet will offer chances to people to establish businesses with limited capital. It’s happening now as there are lots of people in places like India becoming very successful online with limited resources.
If you’re looking to escape that boring 9-5 office job and thinking it might not be achievable, please don’t give up heart. You don;t have to be a YouTube media sensation to escape, a simple blog or eCommerce store is not that hard to set up and can be the key to a new life. Just start looking at the internet in a different way, try to look at what you use it for and look for opportunities there. There are opportunities everywhere if you look properly, only yesterday I bought a product allowing me to access US Netflix trial from the UK, yet another business which the internet has brought us.
Some of the best value gadgets are of course not brand new but a few years old, I found a little beauty called the Squeeze Box radio for a very reasonable price. These were extremely expensive when they first came out but now can be picked up for almost half the price. They have also had a few firmware updates to sort out various issues that were reported when they were first released. Cool design, cutting edge technology (now fixed) and a huge discount in price plus a great design – what could be better?
The Squeezebox Touch is a big upgrade from its little sister, the Squeezebox Radio. With a 4.3inch color touchscreen display, the same build quality and sound quality that made the Squeezebox Radio so popular, some are seeing the Squeezebox Touch as the first truly dependable wireless touchscreen radio.
Wireless radios connect to your home system using Wi-Fi and can subsequently be used to listen to radio stations all across the globe. As a result of the stream being taken straight from the web, there is a noticeable improvement in the quality of the audio when compared to a standard FM receiver. Just touch the “My Music” or “Internet Radio” prompts or one of your many online subscription services like Pandora, Rhapsody or Napster for instant access to your favorite music.
The Squeezebox Radio left many buyers wanting more. Is the Squeezebox Touch really the radio for the job?
I was wowed by the huge 4.3 inch screen in the compact Squeezebox Touch. The fact that it displays in clear, full color is outstanding. It is instantaneous in its response, and the on-screen menus are laid out in a very sensible, flowing pattern.
I really like the album art or available graphics that are displayed as you access different music, podcasts or stations. It keeps the music experience fun, and helps educate you as to what other music may be out there that you would enjoy.
I have to say though that the “pull it out of the box and turn it on” setup is dramatic. Nothing could be easier, and this step really sets it apart from the other internet radios out there. You literally un box it, plug it in, let it find your WIFI, and you are jamming! Whether you want to listen to the BBC, live Australian Rules Football from “down under”, or any of the thousands of free internet stations from around the globe, the Squeezebox Touch takes you there. It also has the ability to add network specific connection details so that you can even add VPN and proxy servers. I am lucky enough to have some great residential ones which I use as private proxies for Instagram. You can actually add them here to access music sources which are often blocked due to your location. In my instance I use them to access Pandora which is geo-locked to the USA only.
Control from your computer is sort of clunky, so I just stuck to the remote, and everything was fine. As I moved the unit around the house, it never drifted or lost clarity. If you have a signal, the Logitech Squeezebox Touch can access your stereo system and deliver your favorite sounds to your home stereo system or other powered speaker set.
Rich Hi Fi Sound
The Squeezebox Touch is designed to connect to your home hi-fi system or powered speakers. It offers “high resolution encoding support for full, rich stereo sound” which is a fancy way of saying this compact, space-saving 10 x 8.5 x 5 inch table-top stereo receiver transfers digital music to full-sound via your home stereo or other powered speakers easily.
The USB port and SD card slot allow access to all your music hardware. And there are a ton of software programmers who have created a load of apps for the Logitech Squeezebox Touch that extend its versatility even further.

In the event that you are truly adventurous, then you can try residing in a holiday villa, where you will be able to possess a first hand experience of both the culture and style.
You’ll also find now large communities of English speaking expats in many of the large Portuguese cities and especially on the coastal regions. They do tend to blend in with the locals though and you’ll find them mixing in with the local nightlife too. The internet has made moving to places like Portugal easier, in the passed many have found it difficult as English is not as widely spoken as in many European countries. Nowadays they can slowly integrate while learning the language, after all you can even watch UK TV online in Portugal nowadays if you use a VPN and a decent internet connection.
The climate of Portugal is additionally among the primary reasons why it has become a popular location over the years. The capital city, Lisbon, normally has a warm and comfortable climate with a quite sunny and warm spring and summer, with an average temperature of about 30ºC. But, winters are regularly blustery and wet, with approximately around 10ºC. However, the general climate for the majority of Portugal is neither too hot nor too cold, but instead just ideal.
Experience the Music
This is just one of the most distinct aspects of your Portugal vacations, because the live musical experience can essentially add a ton of fun and excitement to your vacation. As with any country, music is most certainly a significant aspect of their culture, nevertheless Lisbon particularly has one of the most brilliant musical forms, known as the melancholic fado. The very best method to experience the music is through Lisbon, the place you can easily discover various fado clubs around the Bairro Alto and Alfama neighborhoods.
Naturally, Portugal is celebrated for it’s Port wine, but also for the various light wines which typically use a variety of indigenous grapes. You can find a substantial assortment of wines in addition to vineries across the country. This could be among the most luxurious parts of your Portugal holidays, and the very best place to go for this is Oporto, as they are definitely famous for port wine.
Virtually every perfect vacation includes a breath taking sight of the ocean, and Portugal most certainly provides there. With the Atlantic ocean surrounding the south and west, the coastlines of Portugal are famously known to be attractive. In the event that you are more energetic and would like to pursue a more adventurous holiday, then you can try a variety of water sports on Portugal’s coast. If you love the water, you might want to find an excellent coast holiday where you can go for a swim, snorkel, water skii and even windsurf. You may well also wish to try diving or if you enjoy fishing as a sport, Algarve is well-known for big-game angling.
Lastly, Portugal is a perfect tourist destination because it essentially houses such a variety of breathtaking adventures in one. You can unwind on the beach, tour the ancient architectural master pieces, or just simply soak up the noises, smells, tastes, and sights of the culture and stunning surroundings.
There are only a few sporting events which can claim to attract a truly global audience and the World Cup is definitely one of them. Although there has been some controversy about the bidding process, worries about the political situation and indeed the reputation of Russian hooligans, ultimately that will all be forgotten when the teams face off. Thousands of football fans across the world, will have spent months planning their trips and indeed it’s a testament to the love of the game as Russia is not the easiest place to travel to.
For soccer fanatics everywhere, there really was a bit of nervousness the moment Russia was declared as the host of this yrs world cup. So far the fears seem to have been unfounded at least with regards the infrastructure required to host such an event. Undoubtedly the primary worries are about potential violence as well as what sort of welcome football supporters will be given but it’s likely that all of these will not be issues either as President Putin is keen to use the occasion in order to promote Russia.
He will not be the first leader to reckon on a huge economic boost on the back of the tournament. In passed years this has not been as large as hoped for, certainly the South African economy didn’t benefit quite as much as many had hoped. It certainly will bring an exciting atmosphere to the football fans who are little bit more adventurous than those of us who will have to settle with watching the Match of the Day stream over the internet.
What can the economy expect? Well it will almost certainly bring a short term boost to the economy in many sectors. The Russian Central Bank is hoping that the boost might be somewhat targeted as it has placed stadiums in areas of the country which require this type of financial investment. The increase in spending was probably required anyhow, so the chance to recoup some investment is definitely welcomed by Putin. He is obviously hoping to exhibit the country as a worldwide superpower once more, and it’s very likely that spending will be rather lavish in some public facing areas in addition to in safety and security.
There certainly ought to be an expansion in jobs and a similar boost in the demand for consumer product and services. This ought to continue the positive growth that the Russian economy has experienced in the last year after a sharp fall in the previous two years mostly pertaining to the oil price.
The competition is spread out over 11 cities and it is strongly believed will generate an additional.2% of gross domestic product in both the second and 3rd quarters. This does not sound huge but it is in fact a huge rise in response to a single event like this. President Putin’s hold on power though is heavily reliant on improving the living standards of the average Russian. There is a danger here though in that inflation is most likely to rise particularly in those cities as lots of visitors arrive in a short time.
These types of price rises will probably occur in things like hotels plus ordinary goods and services in line with the increased demand. The Russian authorities are however likely to clamp down on any excessive profiteering and abusing visitors. Lots of tourists have been in fact attempting to bypass these cost rises by scheduling using a VPN or proxies like these in order to access domestic prices wherever possible.
So you’ve decided on a European vacation, you’ve checked the flights and booked a few weeks off. But the choice is huge, Europe is packed full of fantastic places to visit especially for those seeking history, art and a gastronomic experience. So with all this choice, why should you consider choosing to visit one of the most popular European destinations – France? The answer to this question is as varied as the nation. Why visit France? Go to for the culture, the food, the wine, the art, the architecture, the celebrations, the activities, the atmosphere, the scenery, the chateaus, and all the other wonderful things found in France and belonging to this fabulous country. There is genuinely something for everyone here, no matter what your personal interest.
The majority of those who fly into Paris invest a few days or a week seeing the popular museums and travelers sights. There’s enough to see that would fill a go to enduring years. Beyond the Eiffel Tower, Musée de Louvre, the Arc de Triomphe and the Champs Elysées, the Musée d’Orsay, Notre Dame Cathedral, Centre Pompidou, Sacré Cœur and Montmartre are gardens, parks, monuments, and restaurants galore. And when the weather conditions allow, there’s no more desirable place to walk and explore.
Don’t worry about feeling disconnected, all the major cities in France have wonderful internet access indeed normally much better than US ones. If you take with you a mobile device, then you can keep in touch wherever you go with fast access usually free or a few Euros at most. Personally I always use a British VPN service so I can keep watch the BBC when in France like this post illustrates,
However many individuals who check out France never ever get beyond Paris. That would be a big error. Although Paris is an amazing, vibrant city with lots to see and do, by getting outside the capital and into the countryside, you’ll see a totally different side to France. The little rural towns have a special character reflected in the region where they lie. From the coast of Brittany to the pebble beaches of the Côte d’Azur to the sunflowers and lavender fields of Provence and the hills and mountains of the Rhône-Alpes, each area has something unique to provide.
No matter size, each town has a weekly market, where farmers bring their products for sale. Driving numerous hours south of Paris, you’ll discover the Loire Valley, house of a few of the most exceptional chateaux in France. Here you can discover Chambord, Amboise, Chaumont, Chenonceau, and many other grand chateaux.
Continuing further south are the lavish fields of Provence. And beyond this is the French Riviera. Here you’ll find water sports, beach activities, painting, museums and galleries of every description, fantastic fresh food, and marvelous wines. Living is luxurious and costly here – there are sophisticated rental properties along the coast at Cap Ferrat, just down the coast from Monaco, and in the cliffs above. Pebble beaches extend from Good past Saint-Tropez, Cannes, and Antibes, and throughout the summer season they can be crowded.
Nice has something for everyone, no matter exactly what you may searching for. There’s an opera house, a wealth of museums, gardens, hiking tracks, cycling, horseback riding, sailing, wind browsing, gourmet dining, and the list goes on.
Beyond Nice are the towns of Arles, Aix, Avignon – all worth a see, particularly if you enjoy art and painting. This is where Van Gogh and Cézanne painted their landscapes. Lavender fields and sunflowers can be seen everywhere. The surroundings is particularly stunning.
Driving to the Dordogne, there are a variety of lovely towns to explore, consisting of Sarlat. Close-by are the well-known caves of Lascaux and Lascaux II, and the Roman ruins of Périgueux.
And naturally there are the wines of Bordeaux and the Champagne area, and the apples and Calvados of Normandy. France has so much to provide, regardless of where in the country you occur to be. So if you’re planning to have an amazing time and a great adventure, you’ll understand why to go to France. Check out for the good life. And you’ll be rewarded with a fantastic experience.
Further Reading – How to Watch British TV Abroad
If you’re of a certain age, i.e younger than me then you’re probably aware one of the hottest fashion items are sneakers (or trainers in the UK). The big sports firms routinely release ‘special edition’ sneakers and they are extremely difficult to obtain. Although they’re supposedly available online, it takes a huge amount of luck and persistence to actually get a pair.
There are options though and with a little investment in some technology tools you can either grab the latest pairs for your own enjoyment or make a few bucks reselling them. Now it sounds a lot of trouble to go to but these sneakers are really hard to obtain and without software your chance are limited. There are actually quite a few software programs or ‘sneaker bots’ which you can buy and all they do is repeatedly try and buy the latest pairs until they land in your shopping basket at which point you can check out. Unfortunately there are complications as because they simulate multiple buyers, then they tend to get blocked if you do it all using the same internet connection.
Lots of people devote literally 1000s of dollars a month on using proxies, a reality which surprises many. Anyway if you perform a quick google search you’ll spot lots of lists of absolutely free proxies everywhere. Many are actually listed as being super safe and secure and elite, so why in the world do people invest lots of money on them.
Well firstly, it’s important to remember in which any person who has the vaguest idea regarding online privacy, anonymity and the dangers of cyber crime would never go anywhere near a free proxy server. At best there poorly managed proxies unintentionally left available by some overworked on-line admin someplace, which in turn means that you are actually essentially stealing bandwidth in the event that you use them. At worst, and also it’s an increasingly likely scenario the proxy has actually been exposed consciously in order to rip off user credentials such as emails, accounts and security passwords. It’s not much of an option actually, so you ‘d be encouraged to stay well clear of them.
There is a big market for safe and genuine proxies for a variety of uses and one of the more popular is actually buying sneakers from online website retailers. You see all the big retailers of sneakers (trainers in parts of Europe) release limited edition versions of their sneakers which are very much in demand. You can try and buy them online but it’s very difficult to do and you ‘d have to be very quick and luck to even grab even a single pair.
Obviously because they’re scarce and useful then some people want to obtain lots of these– there’s an obvious revenue opportunity there even if you usually do not prefer to use them. Therefore exactly how do individuals get to buy loads of these sneakers on-line from places like Supreme, Footlocker and Nike well these guys pretty much use software.
There are lots of automated tools and bots which anyone can configure to attempt to purchase these sneakers the moment they become available. If you get the right set up you can buy loads of these for whatever function you like. The software acts like a human customer but with infinite patience repeatedly trying to buy the specified sneakers up until they achieve success. Considerable amounts of people buy up loads of these and certainly run successful businesses simply re-selling these sneakers at inflated costs.
TO maximise their opportunities they set up the software programs on high availability hosting servers with considerable amounts of bandwidth. These could be programmed remotely to jump into action as soon as a new release becomes available.
The problem is that naturally the sellers really don’t like this and try and block out access to all automated efforts to buy the sneakers. They identify things like multiple connections from the exact same IP addresses and prohibit these instantly. Which implies even in the event that you possess your own server if it attempts to frequently to purchase the sneakers then it will certainly get banned and the server and software program will be simply of no use.
The solution is to incorporate another level of protection by employing sneaker proxies to hide your geographic location and permit the software or Bot to rotate it’s identity in order to keep operating. It’s not actually difficult to do but the important requirement is that these are sneaker proxies with a specific configuration.
The first important component which you’ll never get with free proxies is actually to make sure it has lots of residential IP addresses. These are actually rather hard to obtain since these types of addresses are actually only normally handed out by ISPs to home users. Most online retailers understand that people try to hide their geographic locations and typically block all non-residential IP addresses by default. Typical commercial VPN and proxies will certainly have commercial IP addresses so won’t work in this situation – you need a residential proxy in order to succeed.
This is what makes sneaker proxies so unique, they need to definitely have residential IP addresses that makes them virtually undetectable from typical home users. It’s also what makes them so expensive as obtaining, supporting and running these sorts of residential proxies is pretty costly.
For any sporting fan, the referee is rarely a popular figure. When they make decisions that benefit our team we’re happy but suggest it was obvious. However when they make other decisions, there’s normally a torrent of abuse or criticism. Basically it’s a very difficult job and one where you really can’t win. If anyone has sat on the touchline of any football game and listed to the comments a referee or assistant gets then you’d be amazed that anyone actually wanted to do the job.
For years now though technology has been creeping into all sorts of sports, primarily aimed at assisting the officials in particularly difficult or crucial decisions. No major sport really relies completely on humans currently although some sports use computers and technology more than others.
Football has always been one of the front runners in utilizing technology partly because it is one of the richest sports in the world of course. The latest development is the Video Assistant Referee system (also known as VAR) which is being trialed in various leagues across Europe at the moment.
My first encounter was watching the Tottenham Vs Rochdale FA Cup final which was broadcast last month. However watching it on Match of the Day online, here’s how to from abroad, It did little to reduce controversy during the match in fact it did quite the opposite.
It’s first appearance was when Spurs took an early lead, yet after consulting the VAR the goal was ruled out. The reason was rather unclear but it appears a foul was committed in the build up to the goal. However a few minutes later VAR was consulted again and confirmed a penalty which was duly scored. Again the decision looked fairly dubious after the event and it certainly lead to some long delays in the game.
The VAR operates on three stages – incident, review and decision. It is supposed to be used in only four specific category of decisions which are deemed ‘game changing’. It’s not designed to be used frequently and VAR should only be used to check serious omissions and only in match changing situations. All the officials involved in the game can recommend consulting VAR but only the referee can initiate the process.
The referee is the only person who can decide whether the original decision should be altered by the VAR system or ignored. Indeed the referee can also use the option to review television footage themselves on a pitch side monitor. This is usually a last resort though as it obviously causes substantial delays to the game and it’s flow.
The sort of areas that the VAR is designed for are things like goals, penalties and serious incidents which could lead to red cards. All these can lead to the result being directly affected
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.
