Grids, Golden Section, Swiss style — the human eye enjoys simplifying the world, creating order, and finding patterns. The desire to frame, contain, and understand is instinctive. The photographer finds frames within frames.Grids are easily perceived, and boxes are everywhere. Architecture makes regular use of repeating structures and details. Bookshelves and windowpanes — the world has a way of aligning its elements.There is efficiency and elegance to the grid form, but there is also beauty in the chaotic, the random, and in nature’s proportions. Human activity and the whimsy of the natural world collide with the well-tested structure of the grid.Admire a campus that frames, and challenges, borders. 5The Museum of Comparative Zoology and Hoffman Laboratory meld forms and reflections. 7Holden Chapel, built in 1744 and among the oldest buildings in Harvard Yard, is framed in the windowpanes of Harvard Hall. 14Concrete slabs comprise the walls, floors, and stairwells of the Carpenter Center.

  • Logie blasts Red Force

    first_imgPORT-OF-SPAIN, Trinidad (CMC):Head coach of Trinidad and Tobago Red Force, Gus Logie, has blasted as “disappointing, frustrating and embarrassing” his players’ performance against Windward Islands Volcanoes in their final match of the regional four-day tournament.Red Force suffered a seven-wicket defeat to Volcanoes at the National Cricket Centre in Couva on Monday, leaving the hosts in fourth spot after finishing second-to-last in the previous edition of the tournament.Chasing a victory target of 166, Windwards, resuming from their overnight score of eight without loss, coasted to 169 for three by midafternoon to end a long four-day season on a high.”I think disappointing is a nice word to use. This is as frustrating as it can get. We’ve tried everything possible to make sure that players are comfortable so they can perform,” said Logie.”We came into this game knowing that a win would have (got) us to third spot. It’s frustrating to see the lack of pride, the lack of fight from some of our players, especially the last two games.”Red Force finished the season in fourth position after accumulating 81 points in the tournament.Their inconsistency showed-up within the space of a month, when they hammered Leeward Islands Hurricanes by nine wickets, but followed up with successive seven-wicket losses to the Barbados Pride and Volcanoes, respectively.”Two weeks ago, we talked about seeing maturity in some of the players and (now), if you look at the way we got out in the middle, it was just embarrassing,” said Logie, a former West Indies batsman.”Our bowling seemed to lack some bite, and at the end of the day, it was just poor cricket.”RUNS TALLYOnly four Red Force batsmen tallied over 400 runs.Kyle Hope from Barbados totalled 553, ex-Guyana and West Indies all-rounder Narsingh Deonarine 494, Evin Lewis with 442, and current captain Yannick Ottley 404.Lewis and fellow left-handed opener Jeremy Solozano were the only Red Force batsmen to score centuries in the 10 rounds of matches.In the bowling department, only leg-spinner Imran Khan (43) and off-spinner Jon-Russ Jagessar (22) collected over 20 wickets.”We’ve seen growth in some individuals, but that’s just not enough. When we give (the players) opportunities, they have to grab it,” said Logie, the former West Indies vice-captain.”With all the support that (they) have, there is no excuse for not going out there and performing. There will come a day when they will have to answer and we will have to find players who will want to play, it’s as simple as that.”last_img read more

  • Jockey Hubert Bartley is dead

    first_imgHubert ‘Chinna’ Bartley, one of the finest jockeys to ride at Caymanas Park in 40 years, died on Tuesday morning at age 54. Bartley, who had been ailing recently, made his mark in the early eighties, winning his first of three jockeys’ championships in 1983. He repeated the feat in 1986, rounding off the triple in 1991 when winning the derby for the first time aboard the outstanding filly POORLITTLERICHGRL for the Bucknor family. Bartley won the derby for a second time in 1997 with the Adin Williams-trained MR. LOVER LOVER. As far as the classics are concerned, the jockey with the flat effective ridingstyle will best be remembered for winning the Jamaica St Leger as many as six times. He also won the 1000 Guineas four times, including a popular win aboard WHO’S THAT GIRL in 1988 for trainer Vin Edwards, his apprentice master and ‘father in law’. Due to recurring weight problems, ‘Chinna’ was sidelined for long periods in the past 15 years, putting a damper on his career. He actually attempted a comeback on two occasions, the more recent at the backend of 2014. He rode his last winner, ST BRUNO KID in February 1981 for trainer Dalton Comrie in the first race on Saturday, October 25 and disappeared quietly into the shadows with 751career wins from 3,349 rides. Bartley, who hails from May Pen in Clarendon, started out in racing as a stable lad with trainer Victor Rodriques in the late ’70s. He soon took a liking to riding and rode for the first time as an apprentice in October 1980, notching his fist win aboard BEAU VENTURE that year. And his rise was meteoric, as two years later, he was crowned champion for the first time. Bartley is survived by family and friends, including a son, Ricardo Bartley, who is not only well known in cricketing circles having represented Kingston College as an opening batsman in the Grace Shield, but served as a young assistant to trainer Vin Edwards before leaving to attend school in the United States.last_img read more

  • Primordial Soup as a Wizard’s Potion

    first_img(Visited 58 times, 1 visits today)FacebookTwitterPinterestSave分享0 Certain concepts in materialistic origin of life seem to have more to do with witchcraft than reputable science.If “space aliens” were replaced by “gods”, “primordial soup” were replaced by “witches’ brew,” and “building blocks of life” were replaced by “magic potion” in modern origin-of-life lingo, would it be less scientific?  If spells could be cast by computer, would they be less occultic?  All such terms provide similar functions: conjuring up mental pictures that lure one into a gratifying sense of numinous awe, deep understanding and control over the forces of nature.  It might be different if the origin-of-life (OOL) field had something to show for itself after decades of work.  But as the following headlines show, there’s more mythology to report than science—maybe witchcraft, even.  One might say that the wishful incantations over Stanley Miller’s fiery spark-discharge bubbling cauldrons have only brought double double toil and trouble.Wizard’s book of spells:  Like Lucy at the incantation book in Coriakin’s palace, David Deamer pores over the magical spells of OOL published by Franklin M. Harold in his new book, In Search of Cell History: The Evolution of Life’s Building Blocks.  In this Nature book review, Deamer “welcomes a synthesis of what we know about the origins of life, as told by a master in the field.”  This “wonderful book,” Deamer says, is by a magician for magicians: “This is, after all, a story to conjure with — that of how life began and evolved into eukaryotic cells, a hundred trillion of which compose the human body.”  Surprisingly, though, Deamer does have “a quibble” with the master sorcerer:I do have a quibble. Harold argues that, notwithstanding the vast literature, progress has gone little beyond the findings of Soviet biochemist Alexander Oparin and British polymath J. B. S. Haldane more than 80 years ago, when they independently argued that Louis Pasteur‘s dictum ‘All life from life’ was wrong. Oparin and Haldane theorized that life may have emerged on a sterile prebiotic Earth through a series of chemical and physical processes.I confess to being more optimistic than Harold. There has been extraordinary progress in understanding the principles by which life works at the molecular level, and that can be applied to the question of how life begins. Over the past eight decades, it has become clear that the basic molecules of life can be synthesized through well-understood chemical reactions. The Strecker synthesis, for instance, produced amino acids from methane, ammonia, hydrogen and water vapour in Stanley Miller’s famous 1950s experiment testing the Oparin–Haldane hypothesis. Furthermore, amino acids, nucleobases and lipid-like molecules — the building blocks of life — are present in carbon-containing meteorites. That makes it entirely plausible that similar organic compounds were available on the prebiotic Earth, waiting to be caught up in whatever process led to life’s beginning.Forgot the sulfate:  The bat wings and spider eyes were fine, but the OOL witches forgot the sulfate, Astrobiology Magazine suggests: “Life in Earth’s Primordial Sea Was Starved for Sulfate.”  Would the experiments had turned out differently without it?  “At these trace amounts, sulfate would have been poorly mixed and short-lived in the oceans,” Sean Crowe says of new estimates that are thousands of times lower than previous estimates.  “—and this sulfate scarcity would have shaped the nature, activity and evolution of early life on Earth.”Alien soda:  On Space.com, Charles Q. Choi speculates that “Alien Life Could Thrive on ‘Supercritical’ CO2 Instead of Water.” Anything is possible when observations are hard to come by.  Maybe alien life could drink lava, or even enjoy cyanide in its coffee.  One astrobiologist enjoys this armchair activity: “I always have been interested in possibly exotic life and creative adaptations of organisms to extreme environments,” says Dirk Schulze-Makuch from Washington State.Brew recipe:  For Live Science, Chidinma Okparanta of the National Institutes of Health provided a shopping list for primordial soup.  In “Cells By the Number: Facts About the Building Blocks of Life,” Okparanta tossed out what look like random numbers – 0.003, 1665, 200, 3 to 5, 120, 24, and and 50-70 billion.  To these numbers he assigned values from the biology of living things, such as 120 days for the lifetime of a red blood cell, and 3.8 billion: “That’s how many years ago scientists believe the first known cells originated on Earth.”  There are 200 cell types in the human body, the article says.Overseas delivery:  Glycerol, a “key building block of life,” could have come from space, researchers at the University of Hawaii imagine.  They even cooked some up in their ultra high vacuum cauldron.  The other wizards must not like the fact that “This work challenges an alternative theory that glycerol and other prebiotic cell components were synthesized on Earth under hydrothermal conditions.”Through the looking glass:  Has the key to the dark secret room of the origin of homochirality been found?  Robert F. Service, writing in Science Magazine, offers hope to the dejected.  First, the bad news:Thirty years ago, researchers including Gerald Joyce, then a graduate student at the Salk Institute for Biological Studies in San Diego, California, showed that if a nucleotide with the opposite handedness was incorporated into a growing D- or L-RNA complementary strand, it shut down all further growth. “It acted like poison,” says Joyce, who is now at the Scripps Research Institute in San Diego.This discovery raised a conundrum for origin-of-life researchers that they’ve struggled with ever since. Before life got its start, D- and L-nucleotides would likely have been equally abundant in the primordial soup. If so, how would RNA enzymes ever have managed to get the RNA copying process going without it being poisoned?Chief OOL wizards Gerald Joyce and Jack Szostak come to Robert’s service by proposing that a particular RNA ribozyme they engineered via “test tube evolution” (a form of intelligent design) was able to assemble RNA strands of one hand out of a mixture.  That “could” have been the secret in the primordial soup, but the wizards will never know: “However, Szostak says, it still begs the question of where such D-RNA and L-RNA ribozymes would have come from in the first place. The answer may be forever lost to history, Joyce says.”  The article was followed by a shouting match between low-information creationists and evolutionists in the Comments.Scripps Institute paraded its chief wizard Gerald Joyce before the multitudes, celebrating his “test tube evolution” experiment that he thinks supports his long-championed “RNA World” recipe for OOL brew (2/15/07, 7/11/02), supported by federal grants by NASA and the NIH (what this has to do with national health is anyone’s guess).  The press release (but not the origin of life) was replicated on Science Daily.Soup comin’ right up:  NASA’s Astrobiology Magazine is giddy to announce that “Scientists create possible precursor to life.”  A precursor to life is obviously not alive, but that’s just a technicality.  It’s quite a leap from the “building blocks of life” to a “protocell” (which is also not alive, at least until natural selection kicks in, they think), but Europeans may have struck a flint: OOL researchers at the Center for Fundamental Living Technology (FLINT) at the University of Southern Denmark conjured up a virtual protocell in their computers.  In the real world, the article notes, polypeptide strings break up in water, and any lucky protein-like string would not replicate without enzymes.  In the computer, though, miracles are possible.  “In our computer simulation – our virtual molecular laboratory – information strings began to replicate quickly and efficiently as expected.”  That’s because they programmed the computer (their “virtual pot” or cauldron) with that expectation, to generate strings and make them interact.  Did they try this in a real-world sterile flask?  Nope.  “We of course don’t know if life actually was created this way,” they say; “– but it could have been one of the steps” (see perhapsimaybecouldness index).Do you need any further evidence that OOL research is a modern form of witchcraft?  To these sophisticated animists, Nature is animated with the spirit of progress.  Dreamer Deamer thought it “entirely plausible that similar organic compounds were available on the prebiotic Earth, waiting to be caught up in whatever process led to life’s beginning.”  He himself is caught up in the spell.  Too bad real chemicals don’t do what they’re supposed to do.  “Whatever process” — there’s science for you.  Whatever.  Stuff happens; it’s a law of nature.  It makes predictions, doesn’t it?  If something happens, you know there was stuff around.  Just add the building blocks of life to the primordial soup with a little bat wing and spider eye, make the right incantation, and poof!  It’s alive!Scientific realism should take seriously the work James F. Coppedge published back in 1973, 20 years after the Miller Myth took over the world.  One of the first modern writers to use the phrase “intelligent design,” Coppedge showed beyond reasonable doubt (far, far beyond reasonable doubt), that the probability of life’s origin by chance was so astronomically low, it was totally and completely unreasonable to imagine life arising without an intelligent cause.  Portions of the book are available online, but we hope to make an eBook copy of his classic available within a year.last_img read more

  • Jenkins wins sixth Fish Marathon title

    first_img“I’m absolutely over the moon,” said Eray. “Daniel won the Fish when I was in matric, so to now win the race myself all these years later and take over from him is amazing. Olympic bronze medalist Brigitte Hartley, together with Nick and Paul Burden completed the event successfully together in a K3, while former Springbok captain Corne Krige completed his support of local schools when he crossed the line with race organiser Pieter Marais and Krige’s good friend Billy van Zyl. MenLen Jenkins 5:01.41Hank McGregor 5:01.41Grant van der Walt 5:02.12Greg Louw 5:08.07Lance Kime 5:09.40Cam Schoeman 5:10.27Jacques Theron 5:10.52Brandon van der Walt 5:15.11Ant Stott 5:15.19Thulani Mbanjwa 5:16.28 Jenkins, dubbed the “Fisher King” for his uncanny dominance in the race for more than a decade, was full of praise for his adversaries after seizing control of the race in the closing stages when McGregor was slowed by waves in the Golf Course Rapids. ‘A good race’“I’d definitely rank my first win in 2001 as the most memorable, but it’s still great to have one and it was nice to have a good race against Hank (McGregor),” said Jenkins afterwards. It was a fitting victory as Eray emulated the late Daniel Conradie, who mentored her in her early years as a paddler. “I tried not to do too much work today. With Grant just behind us, obviously he was always going to do his best to catch us and I could’ve tried to fight it, but I decided to take it easy instead and it paid off for me in the end,” he explained. “It used to be faster shooting from left to right, but since they removed the sandbank it’s actually quicker the other way around now, and so I made sure I was on the outside which gave me the chance to get going again first,” said Jenkins. Shot the weirJenkins and McGregor shot the major obstacle in the most unconventional manner when the two of them went over the weir at precisely the same time and remarkably both boats and paddlers paddled on unscathed, with Van der Walt left 20 metres off the pace. “Fortunately, I still had enough of a buffer to portage Cradock and I’m super stoked to have won,” she concluded. RESULTS Van der Walt had to settle for the third step on the podium, finishing 50 metres behind the leaders after a monumental effort on the second stage. Second and thirdKime claimed the silver medal, with her team Best 4 Kayak Centre team mate Abby Adie claiming bronze. “The Sella and the Fish were the last two races he won before he passed away in 1998, and I won the Sella earlier this year and now this just incredible,” she explained. “It was a good race, though. It was close the whole way and was anyone’s race all the way up until Cradock Weir,” he added. Fourth placeLocal hero Greg Louw powered his way into fourth place ahead of Lance Kime and Cam Schoeman. “It was a different win. It was a really strong field this year and there were a lot of good guys here. Hank and Grant (van der Walt) are fantastic athletes, so it was tough. “There were six world champs in their various categories out there this year and only three of them finished ahead of me, so I’m very chuffed,” he smiled. Having started the day together, the pair was caught by Van der Walt between Long Acre Bridge and Gauging Weir, and the three then made their way towards the notorious Cradock Weir. After a titanic battle with Hank McGregor, Len Jenkins raced to a sixth victory in succession in the Hansa Fish River Canoe Marathon on the weekend and with it claimed the 2012 South African K1 River title. SAinfo reportercenter_img Overcame injuryThe win was even sweeter for Eray after the former Olympian was forced out of action by a debilitating wrist injury for much of 2011. This year’s event was her first major race, other than her efforts at the recent World Marathon Championships in Rome, since August last year. Ladies’ raceThe overnight leader in the ladies’ race, Michele Eray, enjoyed a career highlight when she crossed the line ahead of former champion Robyn Kime to become the first Eastern Cape paddler to win the K1 title in 15 years. “I didn’t quite realise Cam was that strong and Lance was just impossible to shake off,” said Louw. “Cam had an unfortunate swim at Gauging Weir, though, and I went over Cradock Weir ahead of Lance, and from there I just put my head down and managed to get clear. “Today was meant to be easier with it being shorter, but I actually felt worse than I did yesterday. I just tried to keep it at 90 percent throughout the day and a group of guys caught me early on, so I stayed with them until my swim at Gauging Weir.” “I also didn’t swim today, which helps things and which doesn’t happen often for me. McGregor, however, was not done and put in a superb interval to catch and pace the defending champion. A rare mistake through Golf Course Rapid by McGregor gave Jenkins the gap he needed and through he went. “I felt a little stronger today than yesterday, but Mich (Eray) was just too good,” said Kime. “It was a great race, though, and as always it was lots of fun. “Obviously I haven’t exactly had the most ideal preparation for this race, with not much time to train, so I just had to go with what I knew,” said Eray. Jenna Ward had a superb two days as she came home in fourth place, with ICF World Marathon Series champion Hilary Pitchford rounding out the top five. Jenkins and McGregor had been neck and neck for the majority of the two-day, 82 kilometre event and for the first time in decades it came down to an end sprint to separate the pair, with Jenkins edging ahead of McGregor just meters from the finish line. “I couldn’t see Mich by the time I got to Cradock, so decided just to go for it and it was great to make it cleanly,” she added. Age group titlesGrant van der Walt claimed the men’s under-23 title ahead of Lance Kime and van der Walt’s younger brother Brandon, while it was Robyn Kime, Abby Adie and Jenna Ward who claimed first, second and third in the women’s under-23 section. International paddlers figured prominently once again, with Australian Josh Kippen finishing 16th, just behind Czech Republic star Jakub Adam, who has committed five months to prepare for The Unlimited Dusi in February with his K2 partner Michael Odvarko, who finished 19th. ‘Stopper waves’“After Len got away at Cradock, I managed to catch and pass him after a kilometre, but then I just hit a couple of stopper waves at the bottom, which really slowed me down and I just couldn’t get past again,” said McGregor. “Full credit to him, though. He’s a phenomenal paddler, especially on the Fish River, and deserved the win. He timed it right and it all worked out for him. In the hotly contested junior boys category it was KZN’s Murray Starr who claimed the top spoils ahead of under-16 paddler Louis Hattingh and Murray Haw. The junior girls’ race was just as tight with Jordan Peek winning ahead of Kerry Segal and Kerry Shuter.
