More Optical Design in Eye Retina Than Seen Before

zksweugm

first_imgFor decades, evolutionists have used the vertebrate retina as an example of poor design (dysteleology).  They have mocked how any designer could have been so unintelligent as to get the wiring backwards – with the photoreceptors behind a jumble of light-scattering cells.  Creationists have countered that despite the arrangement, it works well.1  Now, they may have a new debating advantage.  German scientists believe they have found a sophisticated network of high-performance optical fibers that funnels light into the photoreceptors without any loss.    The Register (UK) summarized the finding by German scientists at Leipzig University.  They found a layer of cells that act like a second lens inside the eye, channeling the light right through the opaque layer and putting it right where it is needed.  Their words almost glow:They have demonstrated that light is collected and funnelled through long cells called M�ller cells.  These work almost exactly like a fibre optic plate: a “zero-length window” that optical engineers can use to transmit an image without using a lens….    “Everyone thinks lasers are perfectly parallel, but this is not so,” [Andreas] Reichenbach continues.  “They do diverge.  The M�ller cells behave as a lens, and collect all the light without any loss, just like an optical plate.”    But normal optical plates have simple bundles of optical fibres that collect and transmit the light.  The researchers have discovered that the vertebrate eye has gone one step further and created a funnel shaped cell that allows more light to be collected at the surface of the eye….    “Nature is so clever,” Reichenbach says.  “This means there is enough room in the eye for all the neurons and synapses and so on, but still the M�ller cells can capture and transmit as much light as possible.”Optical engineers might learn a lesson from this design, the article ends.    Even the AAAS news site Science Now was impressed.  In a picture story underScience Shots called “Optical Solution,” (May 2), the caption said,For an organ that delivers such crystal-clear images, the eye is curiously designed.  Its light-sensing rods and cones lie hidden behind a blanket of nerve cells that carry visual information to the brain.  So what prevents those neurons from obscuring our vision?  The answer may be surprisingly high-tech.  The entire retina is held together by a network of elongated M�ller cells, and these act like optic fibers, funneling light straight through the neural veil to the rods and cones, according to a study published online the week of 30 April in Proceedings of the National Academy of Sciences.  Not a bad trick for a camera designed 500 million years ago.Though a creationist may flinch at that last sentence, no one can fail to notice the D word design – and the absence of evolution language in both articles.  Does this indicate a backpedaling of arguments about bad design in the eye?  It appears the design was more clever all along than anyone imagined.Update 05/07/2007: The paper in PNAS2 appeared on May 7.  The 10 German authors describe in exquisite detail the optical properties of the Muller cells, and how they measured them.  They said that each cone cell (color photodetector) has one Muller cell guiding the light to it, while several rods (black and white photodetectors) can use one optical fiber.  The entire front surface of the retina is effectively covered by the cone-shaped entrances of the optical fibers, which guide the light directly to the photoreceptors, bypassing the other cells which would otherwise scatter the light.  Each Muller cell has a variable index of refraction tuned to the light to maintain the optimum wave-guiding properties and reduce loss by reflection.  The authors say in the final discussion, “the increasing refractive index together with their funnel shape at nearly constant lightguiding capability… make them ingeniously designed light collectors.”  There is no mention of evolution in the paper.1For example rebuttals, see creationist articles on CSI by Peter Gurney and Carl Wieland, and ID responses on ARN by George Ayoub and Michael Denton.  See also CEH entries from 05/09/2002 (“Best of all possible optics?”), 05/27/2003 and 05/22/2003.  Consider also the sharpness of the eagle eye, or the eyes of a diving cormorant, 05/24/2004.2Franze et al., “M�ller cells are living optical fibers in the vertebrate retina,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0611180104, published online before print May 7, 2007.The dysteleology argument against the vertebrate retina is now dead.  If you ever hear it raised again, point the evolutionist to this paper.  Who could have imagined that advanced waveguide technology was built into the vertebrate eye?  The scientists used guinea pig eyes in their research.  Are we supposed to believe that guinea pigs and even smaller vertebrates are the leading optical designers in the world?  Come on.  No more do we need to hear the mocking of Darwinists like Jared Diamond (see non-sequitur in the Baloney Detector).  Darwinism is out for the count on this old argument.  The vertebrate eye is superbly designed all the way down.    Creationists don’t need judges to decide in favor of their position.  They just ask for better observations of the facts that are there for the seeing.  Read this, you mockers.(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

News about Tagore’s song confusing, says scholar Sankha Ghosh

ronplzeq

first_imgThe “new song” of Rabindranath Tagore, claimed to have been found recently, is “rather confusing information,” said West Bengal’s eminent writer and scholar of Tagore’s works, Sankha Ghosh. Talking to The Hindu about the poem —There Are Numerous Strings in a Lute — Mr. Ghosh said the fact that “the song has a tune and is set in western classical musical tradition by Tagore himself is exciting information.”‘Published in 1918’“But, if this information gives out an impression that the poem was found for the first time, then it would be erroneous. [Because], in 1918, it was published in a book of poems called Crossing. It was the 68th poem in the collection,” said Mr. Ghosh. ‘Performed in schools’He also added that the song, There Are Numerous Strings in a Lute, was performed in the past in some christian missionary schools as a prayer song. “However, those who performed it were perhaps not aware that it was composed by Tagore,” he said. On March 21, Victoria Memorial Hall in Kolkata hosted a programme in collaboration with Hindusthan Record, where the song was unveiled. The programme, titled ‘Numerous Strings’, was listed on their website. It was noted that the event was the “first live performance of the recently discovered English songs composed by Rabindranath Tagore in the Western Musical tradition.”“Perhaps it [the event announcement] gave an impression that the poem or the song was released for the first time. I think it was a misunderstood leading to some confusion,” Mr. Ghosh said.Mr. Ghosh received the country’s highest literary award Jnanpith in 2016.last_img read more

Colombia’s triple hammer blow dumps Poland out of World Cup

first_imgShare on Messenger Share on LinkedIn World Cup 2018: complete guide to all 736 players Share on Twitter Read more Read more Share via Email For Poland the pattern is frustratingly familiar at major tournaments, and has been since 1982. They qualify well, hopes are raised and then they find that on the highest stage the shirt hangs heavy, players lose faith in what got them there and the result is a safety-first style that results in grouchiness and early exits.Colombia, meanwhile, fight on. Unless Poland do them an unlikely favour by beating Japan they will probably have to beat Senegal to qualify, but at least now there is hope. match reports Reuse this content Pekerman dedicated the victory to Carlos Sánchez, who was sent off in the opening defeat to Japan. Although he refused to confirm whether the former Aston Villa midfielder had received death threats, as has been reported, he did say Sánchez had been “deeply affected”. “I think we all understand that football really is something else. It is ultimately a game we play with a lot of responsibility, dedication and effort and so forth, but these things shouldn’t be said lightly.”Pekerman took responsibility himself for the Japan defeat, admitting he had “made mistakes”. With the combination of Quintero and Rodríguez, though, they had found a way of playing that was “close to the goal of how we wanted to play.” This was probably Colombia’s best performance since the last World Cup; Pekerman sides are always at their best when counterattacking with rapid, precise geometry. Read more Share on Facebook Colombia Share on Pinterest World Cup Forgotten man Falcao determined to make up for lost time with Colombia Poland Rodríguez and Quintero are contrasting No 10s, the modern dynamic runner and the more traditional variant, to be celebrated, perhaps, for what might most politely be referred to as his cerebral approach and economy of movement. Playing them together seemed a major risk, but along with Juan Cuadrado, Colombia’s creative trident picked Poland apart with clinical beauty. “More than once we felt that combination could be a good one,” said Pekerman. “They are two players with extraordinary talent. Tonight they contributed these great talents and played in a very complementary fashion.”On loan at River Plate from Porto, Quintero is a throwback, more cask than six-pack in tone, a player whose reluctance to submit to the more rigorous aspects of professionalism has frustrated a series of coaches. He had already played one astute reverse pass when, after 40 minutes, he played another to find Rodríguez in space on the right. His cross was perfect, and Yerry Mina nodded in from close range. Given he has only completed 90 minutes twice this year, it was no great surprise that Quintero was taken off after 73 minutes but before he went, he played in Radamel Falcao to score with an incisive prod of his left foot. A brilliant Rodríguez pass laid on the third for Cuadrado, who also had a fine game, attacking the space behind the Poland wing-back Maciej Rybus. Topics Share on WhatsApp Poland, unfortunately, continue to be at their best when they are not in tournaments. Adam Nawalka’s switch to a back three, although he had trialled it in the pre-tournament friendly against Nigeria, seemed in retrospect a warning. All through qualifying he had used either a 4-4-2 or 4-2-3-1; this was a sign that that team was effectively over and that, at the worst possible time, he was trying to forge a new one. As he sat helpless in the face of a barrage of hostile questions from the Polish media, the celebrations of Colombia fans clearly audible from outside the stadium, he did his best to defend the indefensible, insisting Poland had simply been beaten by the better side. That may be true, but it’s equally true that Poland were a better side in qualifying.Tactically, perhaps, setting a wing-back in Rybus against Cuadrado was a risk, and one that didn’t come close to paying off, but Poland’s struggles were about far more than that. There was a strange lifelessness about them while Robert Lewandowksi, who had seemed out of sorts towards the end of the season, most notably in the Champions League semi-final, was again listless, nothing like the figure who scored 16 goals in qualifying. Poland 0-3 Colombia: World Cup 2018 – as it happened Sometimes the answer comes by changing the question. Rather than asking whether he should play James Rodríguez – now he was sufficiently recovered from his calf injury to start – or Juan Quintero, and coming up with a fairly obvious response, José Pekerman selected both and was rewarded not merely with a result that keeps alive Colombia’s hopes of making the last 16, but with a performance that made them look like a side that could go a long, long way in the tournament.

Man Utd boss Solskjaer relaxed over Rashfords lack of goals

dmihbinh

first_imgLondon: Ole Gunnar Solskjaer is not concerned by Marcus Rashford’s recent lack of goals, pointing to the Manchester United forward’s hunger and determination to improve. Teenager Mason Greenwood saved his teammates’ blushes on Thursday, scoring in United’s unconvincing 1-0 win against Astana in their Europa League opener at home. United started brightly but Rashford missed a number of opportunities against the champions of Kazakhstan. Solskjaer has spoken of his desire for the 21-year-old to score more goals but is not worried that the academy graduate has netted just once from open play in eight appearances for club and country this season. Also Read – We will push hard for Kabaddi”s inclusion in 2024 Olympics: Rijiju”He’s getting the chances,” the United boss said of Rashford, who has scored two penalties this campaign. “Of course he could have had three today (Thursday). The keeper made a few fantastic saves. “I don’t worry about that, no. We’re working every single day in training with Marcus. He wants to improve, wants to be better.” Asked if United needed more goals from Rashford and fellow forward Anthony Martial, he said: “All the goals we’ve scored have come from the forwards with Marcus and Anthony, and Dan James. I’m sure they’ll chip in with many, many goals. “He is still young, he’ll improve. You won’t hit your peak as a striker until you’re 26 or 27. He’s still learning what finishes to make in different circumstances.” Also Read – Djokovic to debut against Shapovalov at Shanghai MastersSolskjaer expects to be without Martial for Sunday’s match away to West Ham, along with Paul Pogba and Luke Shaw. United, fourth in the Premier League table, could also be missing Wales winger James, who missed the match against Astana with a knock sustained in last week’s victory against Leicester.

first_imgVisakhapatnam: Team India will aim to begin their home leg of the ICC World Test Championship on a high when they take on South Africa in the first Test of the three-match series beginning on Wednesday at the ACA-VDCA Stadium. Virat Kohli’s men would be full of confidence after they consolidated their position as the No.1 side with a 2-0 series whitewash in West Indies, which also saw them earn their first points in the WTC. They would go into the series as undeniable favourites considering their enviable record at home since 2012-13. Ever since the West Indies series which saw legendary batsman Sachin Tendulkar hang his boots, they’ve won each of their 10 series —the joint highest by any team on their home soil. Also Read – We will push hard for Kabaddi”s inclusion in 2024 Olympics: RijijuHowever, the upcoming series against the Proteas will not be an easy one. The quality of the South African side, despite their inexperience, was visible in the T20I series which ended in a draw. And with the likes of Faf du Plessis coming into the line-up, the hosts can be rest assured to face a stiff competition from the Proteas. Kohli will not have the services of his premier pacer Jasprit Bumrah as the latter has been ruled out because of a stress fracture. Also Read – Djokovic to debut against Shapovalov at Shanghai MastersHowever, the No. 1 ranked side will still have the services of Ishant Sharma and Mohammad Shami, who have been in great form in the last two years. But, the biggest talking point of the series — without a doubt — will be Rohit Sharma, who has been given an opportunity to cement his place in the Test side. Rohit, who opens for India in the limited-overs cricket, will be batting alongside Mayank Agarwal at the top of the order. The Indian team management has also decided to give Wriddhiman Saha another opportunity as the 33-year-old has been tasked to keep the wickets in place of Rishabh Pant. On the other hand, South Africa would go into the series with some confidence after their winning finish to the T20I series that helped them earn a 1-1 draw after the first game was washed off. The visitors had a horrid time when they last toured India in 2015 as they had lost three of the four Tests they played. And in the upcoming series, things appear even more difficult as they lack experience, with Dale Steyn and Hashim Amla retiring. However, they would be buoyed by the performance of Aiden Markram, who scored a fluent century in the practice game against Board President’s XI. While skipper Faf Du Plessis and Dean Elgar will provide them with the much-needed confidence with the bat, the bowling unit seems well-rounded with the return of Philander and Lungi Ngidi, and left-arm spinner Keshav Maharaj who will be joining forces with Kagiso Rabada in their attempt to make inroads into the strong Indian batting line-up. India XI: Virat Kohli (Capt), Ajinkya Rahane (vc), Rohit Sharma, Mayank Agarwal, Cheteshwar Pujara, Hanuma Vihari, R Ashwin, R Jadeja, Wriddhiman Saha (wk), Ishant Sharma, Md Shami. South Africa: Faf du Plessis (c), Temba Bavuma (vc), Theunis de Bruyn, Quinton de Kock (wk), Dean Elgar, Zubayr Hamza, Keshav Maharaj, Aiden Markram, Senuran Muthusamy, Lungi Ngidi, Anrich Nortje, Vernon Philander, Dane Piedt, Kagiso Rabada, Rudi Second.last_img read more

first_imgKolkata: A total of 34 functional teams have been formed to smoothen the process of merger of United Bank of India (UBI), Punjab National Bank (PNB) and Oriental Bank of Commerce (OBC), a senior official said. The merger is scheduled to come into force from April 1 next year. “Thirty four functional teams have been created to come out with solutions for the process of integration,” a UBI official told PTI. A team comprises two members each from the three banks from different functional areas, he said. Also Read – Commercial vehicle sales to remain subdued in current fiscal: Icra “The functional teams will also try standardising the loan process, credit terms and benefits extended to the customers in the interim period till the merger comes into effect to avoid customer-related issues in the future,” the official said. The UBI had conducted customer meets at Kolkata, Guwahati and Patna to allay their apprehensions about the future of banking, the official said. UBI managing director and CEO A K Pradhan had earlier said that though the balance sheet merger is likely to happen by April 1 next year, it will take another three to six months after that for the HR and IT integration to be completed.

Senior officials of the three banks had held a meeting recently. The merger will make the new entity the second-largest bank in the country after the State Bank of India (SBI) with a total business volume of Rs 18 lakh crore. This comes after the Centre’s announcement to consolidate 10 public sector banks into four. Allahabad Bank will be merged with Indian Bank while the Union Bank of India, Andhra Bank and Corporation Bank will be amalgamated. Canara Bank and Syndicate Bank will also be merged. Last year, the Centre had approved the merger of Vijaya Bank and Dena Bank with Bank of Baroda that came into effect from April 1 this year. In 2017, the State Bank of India had absorbed five of its associate banks and the Bharatiya Mahila Bank.last_img read more
