Sharks mailbag: Who plays, and who sits once Radim Simek and Dalton Prout return?

first_imgBUFFALO, N.Y. — The Sharks put a miserable first week of the regular season behind them to go 3-1-0 in the last 10 days. Still, there’s a lot of work to do and some questions to be answered over the next few weeks.Here’s a peek at this week’s Sharks mailbag.How close are (Radim) Simek and (Dalton) Prout to returning? Who will be heading out to give them roster spots? (@teal_puck)From your point of view, I’m curious to know which 6D you think the Sharks will play when Simek and Prout are …last_img read more

Submarine Engineers Admire Penguins

first_imgAn ocean engineer from MIT, Franz Hover, says “we never miss marveling at them,” speaking of penguins.  In the cover story of Science News,1 the submarine designer elaborates:Under the power and guidance of its versatile flippers, a penguin can move through the water faster than 10 miles per hour, turn almost instantaneously, and leap out of the water onto an iceberg.  You’ll never see a submarine do that, Hover points out.   (Emphasis added in all quotes.)Carrie Lock, author of the article entitled “Marvels of Engineering,” also marvels at the graceful flippers of dolphins, sea lions and whales compared to the crude propellers of man-made underwater craft.  The shape, maneuverability, and flexibility of animal flippers overcomes turbulence and allows quick turns and near-instant stops:Scientists have long sought to unlock the secrets of nature’s underwater-locomotion schemes, but they’ve usually met with frustration.  Since the mid-1930s, when England’s Sir James Gray declared that dolphins move through water so efficiently that engineering principles were inadequate to explain the mechanism, people have sought to understand marine-animal locomotion.  Now, researchers in the field of biomimetics–the science of mimicking living things–have unlocked some of those secrets and are applying their knowledge to prototype watercraft.The movement of a swimming penguin is “deceptively simple,” because:To accomplish its feats, the penguin must generate forces that are huge in proportion to its small body.  Although scientists can’t fully explain how the animal does it, it’s clear that for its size, a penguin’s stroke creates forces relatively larger than those of a propeller and does it more efficiently….    Penguins are more maneuverable than vessels because their flippers can make different kinds of motions than propellers can.  Penguins’ flippers are attached to their bodies at a single rotation point that’s equivalent to the human shoulder.  The flippers flap up and down, move forward and back, and twist around in the joint.  Propellers, on the other hand, just rotate.  Although they can turn at different speeds, the orientation of their motion is fixed.Lock discusses several teams working on imitating the flippers of penguins, dolphins, and the scalloped-edge flippers of humpback whales, which reduce turbulent wakes (see 05/11/2004 headline)– this is being investigated by a Pennsylvania biologist named Frank E. Fish.  The Navy is looking at all these engineering projects with great interest.1Carrie Lock, “Ocean Envy: Scientists look toward marine creatures to improve watercraft designs,” Science News, Week of Sept. 4, 2004; Vol. 166, No. 10, p. 154.Penguins look funny waddling on the land in their tuxedos, but underwater they are more graceful than ballerinas.  Next time a nature program shows underwater footage of Antarctic penguins, watch it for awhile in wonder.  Then laugh as the camera shifts to land position and films them launching their fat but sleek bodies into the air, only to bellyflop on the ice.  Penguins are cool.  This article barely touches on just one of many wonders of these aquatic birds and their lifestyles in some of the harshest environments on earth.    An important part of the penguin’s flipper design is a pulley-like tendon that threads the needle of a shoulder bone.  How could that evolve?  Every detail in the anatomy of a penguin flipper is superbly adapted to their habitat, but a flipper alone would be useless without the brain software, sensory organs, digestive, respiratory, circulatory and other systems that work together to make all this exquisite ballet possible.  The systems, in turn, depend for their function on tens of thousands of molecular machines in each cell, coded by gigabytes of programmed information.    Congratulations to Carrie Lock for sparing us unnecessary Darwinspeak in this interesting story (except in the references, where a paper has a convoluted title, “Convergent evolution in mechanical design of lamnid sharks and tunas”).  Yes, ask the beasts, and thou mightest learn something.  (To Darwinists, another reference is apropos: go to the ant, thou sluggard.)(Visited 69 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Spurs edge Mavericks in Dirk Nowitzki’s last NBA game

Perhaps the most memorable was the 2006 Western Conference finals against San Antonio. After the Spurs battled back from a 3-1 series deficit and a 20-point lead in Game 7, Manu Ginobili fouled Nowitzki on a layup with 21.6 seconds remaining. Nowitzki made the free throw to forge a tie and the Mavs went on to win in overtime on the way to the franchise’s first NBA Finals appearance.“If it’s not at home, this kind of works perfect,” Nowitzki said of San Antonio. “This team was always sort of the big brother. They were beating us and then we kind of found a way to get through them in ’06. To me, probably still one of the best playoff series I’ve been a part of and probably some of the best basketball in that series that I’ve ever played in my life.”Nowitzki was able to turn back the clock, shooting 8 for 21 in 32 minutes, including going 2 for 6 on 3-pointers. His final shot was a 20-footer over Spurs rookie Drew Eubanks with 49.7 seconds remaining.Dallas coach Rick Carlisle subbed Nowitzki following the shot, leading to an ovation of cheers and chants of “Dirk” and “MVP.”“It’s cool playing against Dirk tonight,” Spurs guard DeMar DeRozan said. “Seeing him out there and playing against one of the greatest of all time for the last time, it was cool. Hopefully, I got a good photo op.”Derozan finished with 19 points and Derrick White added 14 for the Spurs, who finished with a 49-34 record.Justin Jackson and Courtney Lee added 14 points each for Dallas, which was without Rookie of the Year candidate Luka Doncic.TIP-INSMavericks: Nowitzki averaged 15.3 minutes and started 20 games this season, the lowest numbers of his career. He started 24 games as a rookie while playing 20.4 minutes. … Nowitzki has played 38 games in San Antonio, tied for the third-highest total of any player. Utah legends Karl Malone and John Stockton each played 46 games in San Antonio. Denver’s Alex English played 39, and Houston’s Hakeem Olajuwon played 38. … Doncic missed three of Dallas’ final four games due to a thigh injury. He missed back-to-back games against Memphis with a bruised right thigh, played 32 minutes against Phoenix, and missed the team’s finale with a bruised left thigh.Spurs: Bryn Forbes finished with 10 points in 26 minutes. . San Antonio only had four players in double figures. MOST READ THANK YOU, DIRKThe Spurs played a 1 ½-minute tribute video in honor of Nowitzki, highlighting his 21 seasons in the NBA.Nowitzki looked up to watch the video on the big screen at the AT&T Center, but had to turn away as he began to cry.“The first 20, 30 seconds, I was kind of holding it (in),” Nowitzki said. “I was like, ‘That’s sweet,’ and then it just kind of all came out. I’m not sure why. Not only did they show highlights from my career, but they showed highlights from me beating up on the Spurs, which was even more incredible.”UP NEXTMavericks: The offseason.Spurs: First round of the Western Conference playoffs against Denver.Sports Related Videospowered by AdSparcRead Next View comments PBA D-League: Petron-Letran halts Ironcon-UST’s unbeaten run LATEST STORIES PH underwater hockey team aims to make waves in SEA Games PLAY LIST 02:42PH underwater hockey team aims to make waves in SEA Games01:44Philippines marks anniversary of massacre with calls for justice01:19Fire erupts in Barangay Tatalon in Quezon City01:07Trump talks impeachment while meeting NCAA athletes02:49World-class track facilities installed at NCC for SEA Games02:11Trump awards medals to Jon Voight, Alison Krauss Hontiveros presses for security audit of national power gridlast_img read more
