In this video, we see spinning toys with peculiar preferences for direction and orientation, a propeller that rotates by vibrations, and how to screw a nut on a bolt using an electric toothbrush. To learn more, view the “Toys in Applied Mathematics” video. Tokieda is spending his year as the William and Flora Hewlett Foundation Fellow making his scientific toys widely available by developing durable models, Web-based presentations, texts, photos, and movies. He’s also discovering new toys, sharing his ideas with audiences, and developing an exhibition — which opened this month in Byerly Hall — to bring these concepts to the public.Though the toys tend to be simple, the scientific concepts behind them often are not. It’s that combination of a simple object, surprising behavior, and sophisticated underlying principles that Tokieda is looking for, and that he hopes will draw in others from different scientific backgrounds.“It’s not that I knew a piece of science and designed a simple toy to illustrate; I find a raw phenomena … interesting to children and professional scientists alike,” Tokieda said. “Professional scientists may find it even more interesting than a child would. … Children and great professors of Harvard University can share the surprise.”Tokieda’s goal is to convince people that science isn’t just something performed in remote laboratories by formula-spouting specialists in white coats. Rather, it is alive, fascinating, and present all around.“We have the impression of science as institutionalized and of scientists with thick glasses and lab coats,” Tokieda said. “If you believe science is all around us, as it is, you should be able to find science everywhere. It is in the daily life of everyone.”Tokieda grew up in Japan thinking he would become an artist. When he was 14, he left home for high school in Bordeaux, France, where he began studying languages. He later returned to Tokyo to specialize in classics.When he was in his 20s, he picked up a book about a Russian physicist who disdained people not proficient in calculus. Tokieda hadn’t even heard of calculus and set about remedying the situation. Learning first from books and then through formal lessons, he discovered he enjoyed math. He left the classics and continued his studies in mathematics, eventually earning a doctorate from Princeton University and joining the faculty at Cambridge.To find new toys, Tokieda keeps his attitude playful and his eyes open. In the introduction to his Radcliffe exhibit, he describes the oft-cited scenario of a small child opening a present and, intrigued by the paper, playing with that instead of the toy.Many scientists are like an older child opening the same package. They know what’s supposed to be interesting, so they focus on that, forgetting the potential magic of the unconventional: the crinkly paper.“I am suggesting that in science,” Tokieda wrote, “we rediscover the eyes of the child.”Tadashi Tokieda’s exhibit will have extended hours on Monday (Oct. 28) as part of Radcliffe Open Yard, a public event from 4:30 to 6 p.m. that will highlight his show, an exhibit of items from the Betty Friedan collection at the Schlesinger Library, and a new public art garden. In the Byerly Hall Gallery, Harvard students will demonstrate and explain the toys and the scientific principles they illustrate. The exhibit closes on Nov. 1. <a href=”https://www.youtube.com/watch?v=E0_tsHj-JlQ” rel=”nofollow” target=”_blank”> <img src=”https://img.youtube.com/vi/E0_tsHj-JlQ/0.jpg” alt=”0″ title=”How To Choose The Correct Channel Type For Your Video Content ” /> </a> Tadashi Tokieda drops a small cedar ball into an empty soup bowl and begins swirling the bowl on a tabletop with his hand.As the bowl moves in circles, so does the ball. Tokieda adds a second ball and a third, and they swirl, too. When he adds a fourth, the balls’ smooth movements become jerky. A fifth and sixth add to the confusion as the balls are influenced not just by the bowl’s movement, but also by their interactions with each other.A seventh ball triggers something odd. The confusion subsides, and the balls, now influenced largely by their interactions with each other, begin to swirl in the opposite direction of the bowl’s motion. Tokieda explains that the change is analogous to the shift of particles moving freely in a gas to those crowded in a liquid.“A transition takes place,” Tokieda tells the crowd watching his demonstration earlier this month at the Radcliffe Institute for Advanced Study’s Fay House. “It’s metaphorically like vapor condensing to water.”Tokieda, director of studies in mathematics at Cambridge University’s Trinity Hall, is spending this academic year as a Radcliffe Fellow. His day job at Cambridge involves high-level geometry and the mathematics of Hamiltonian systems, a type of mechanics that describes the movement of planets.But Tokieda is also interested in toys.Several years ago, Tokieda decided to use simple toys to demonstrate to family and friends the complex mathematical problems on which he works. As he searched for illuminating objects from everyday life, he came across surprising behavior — sometimes complex behavior — routinely exhibited by simple objects. Eventually, his search for objects with which to teach became a search for objects from which to learn.To date, Tokieda has collected, invented, and analyzed more than 100 “toys,” ranging from spinning plastic tubes to small tops, a Slinky to illustrate tension and gravity, a mug and a spoon to tap out bell-like sounds, and glass jars partially filled with rice that roll down wooden ramps at varying speeds because of differences in how the rice moves inside the jars.Toys in everyday science

This summer the South is loaded with triathlons of all distances—from fast sprints to the long slog of the mighty Ironman.Rocketts Landing Triathlon Richmond, Va. • July 24 Racers traverse the best of Richmond with a 1,500-meter swim in the James River, followed by a rolling 40K bike ride on the rural roads of Henrico Country, and finishing with a 10K through downtown.Charlottesville Off-Road Sprint Triathlon Charlottesville, Va. • July 24 If your racing preferences eschew concrete, try this off-road triathlon at the idyllic Walnut Creek Park, located in Charlottesville’s forested outskirts. After a 750-meter open-water swim in the cool waters of the park’s lake, the course’s 15.5-mile bike ride and 5K trail run will weave through dense woods on well-maintained singletrack with relatively mellow grades.XTERRA Panther Creek Morristown, Tenn • July 31 XTERRA hosts a series of rugged off-road triathlons around the country with 65 races in 35 states. Avid racers earn points as they compete for an invite to the XTERRA USA Championships in Utah. One of the South’s toughest trail triathlons takes place in the Smoky Mountain terrain of East Tennessee’s Panther Creek State Park. After an 800-meter swim in Cherokee Lake, racers complete a 15-mile mountain bike ride and a 4.5-mile trail run.Paris Mountain Triathlon Greenville, S.C. • August 6 This rugged race at Paris Mountain State Park in the South Carolina Upstate was rescheduled from early spring, so sweltering summer temps could be an additional challenge. Besides the heat, racers will contend with the brutal climb of Paris Mountain (over 1,000 feet in a little over two miles), both during the five-mile run and the 20-mile bike ride on the surrounding hilly roads. This is the same climb elite cyclists tackle every year at the U.S. Professional Cycling Championships. The most refreshing part of this race comes early in the 500-meter swim in Lake Placid’s cool and clear spring-fed waters.Ironman Louisville Louisville, Ky. • August 28 Completing the full monty is no small feat: swimming 2.4 miles, biking 112, and running a marathon (26.2 miles). The only full Ironman in the South takes place around Louisville’s scenic waterfront with a point-to-point swim in the Ohio River and running and biking past popular landmarks like Churchill Downs and Louisville Slugger Field. 1 2
(CIDRAP Business Source Osterholm Briefing) – The race is on. The next few months will pit all of our preparedness planning (or lack thereof) against a novel H1N1 virus that is certain to sweep through northern hemisphere countries.While this next wave is not likely to dramatically increase influenza deaths—unless the virus undergoes additional mutations or reassortments—it could cause significant and sustained illness in our otherwise healthy workforce populations. And remember, we currently don’t have any explicit plans to vaccinate that population, except for pregnant women and healthcare workers, even in the United States.Regular readers of this column know I have emphasized for the past 4 months that we should expect the unexpected in our battle with this virus. But now it’s time to drive a stake in the ground and declare, “No more what-ifs. This is what we can and are going to do in response to this virus in our organization over the next 4 to 6 months.”Business preparedness for this pandemic was substantially elevated this past week when the US news media suddenly found the second coming of novel H1N1. Stories about the potential shoe to drop with a fall/winter wave of illness have been everywhere.The media’s attention is not based on any recent change in the disease occurrence, but has largely occurred because of an all-out media campaign by our federal government to hit our pandemic preparedness status head-on. I applaud these federal efforts, particularly the coordinated messages coming from the Departments of Health and Human Services, Homeland Security, Education, Commerce, and Agriculture.Despite the balanced and scientifically sound information being shared by our federal agencies, there are still a number of critics who have publicly declared that this is a “Chicken Little” situation. We are scaring the world needlessly, they say. If that’s where you are as you read this column, go no further. If you aren’t convinced by now that we have some real challenges ahead with this upcoming fall/winter wave of H1N1, I’m afraid it’s too late for CIDRAP to help.Your primary focusBut if you do believe that H1N1 may cause substantial and sustained illness in our workforce over these upcoming months, then understanding what that means, particularly as it is overlaid on a global just-in-time economy, ought be your second highest priority right now.Of course, your first priority should focus on what the next few months will mean for your family and loved ones. As a father of a pregnant neonatologist (my first grandchild is due in December)—and she is also part of the team at the bedside of other H1N1-infected and seriously ill pregnant women—I pray for the day when my daughter gets both of her H1N1 influenza vaccine doses in her arm. It can’t come soon enough.Announcing a crucial summitTo try to bring a very current, practical, and execution-driven summary of what we all can do to have the highest level of preparedness in our organizations, CIDRAP is sponsoring its third pandemic preparedness summit on September 22 and 23 in Minneapolis. “Keeping the World Working During the H1N1 Pandemic: Protecting Employee Health, Critical Operations, and Customer Relations” is the title we’ve chosen for this 2-day crash course and summary of the latest, most effective actions your organization can implement to be better prepared.You can get more information on the summit here. We’re convening pandemic response experts in public and private sectors who know their business and are ready to act. We’ll tackle with candor, urgency, and practicality how to brace our enterprises for the months ahead.The 25 members of the Summit Advisory Group represent some of the best minds and most practical thinkers in the pandemic preparedness business. I think when you review the program and see the line-up of speakers and sessions, you will agree that this will be your last, best chance to get ready for this next wave of H1N1 infections.And I can only hope that one day, when we do all our pandemic postmortems, we will realize we did make a difference.Bottom line for businessIt’s not too late to get some very crucial and practical preparedness planning completed and implemented in your organization. But time is of the essence. No more feeling your way through the preparedness black hole. Execution is everything now. And it helps if somebody else has tried it and is willing to share which best practices worked and which didn’t.
The “Olive Road”, 20 kilometers long, begins in Babino Polje, and leads to Odysseus’ Cave through hundred-year-old olive groves. The path “Sacral treasure of Babino polje” is a short circular, passes through the town of Babino Polje, and leads to churches and chapels that testify to the Christian tradition of the island since the 11th century. The project on Mljet was implemented as part of the Dubrovnik-Neretva County project “Paths of the Past” co-financed by the European Union from the European Regional Development Fund, and is implemented through the Operational Program Competitiveness and Cohesion 2014-2020. The aim of the project is to create and promote the cultural and ethnographic offer of the Dubrovnik-Neretva County. The brochure was printed as part of the project “Rural educational, cultural and ethnographic tourist attraction” for the purpose of promoting landscaped hiking trails in the central part of Mljet. “Drywall Road” is a 500-meter-long trail that represents a cultural landscape shaped by fields and drystone walls, forming a unique cultural and natural heritage unit. The route also includes the core of the hamlets of Ocinje and Zabrežje with volts from the 15th century. The trail “Water springs – old stream” follows a stream with a riverbed that often dries up, testifying to the importance of water for agricultural activities in the area of Babino polje from the Middle Ages to the present day. Along with the Austrian road and the Babino polje thematic trails, the project also includes the Dubrovnik Littoral Native House, the Korčula City Museum located in the Ismaeli-Gabrielis Palace and the Smokvica Gold and Silver Museum. The tourist offer of Mljet is richer for a new thematic tour as long as 20 kilometers, which is presented through a new brochure “Mljet – a mystical oasis”. The aim of arranging themed trails and the Austrian Road is to present the rich heritage of the Island and ensure a longer stay of guests. In addition to the thematic trails of Babino polje, 850 meters of the Austrian road between the settlements of Sobra and Babino Polje have been arranged. A brochure with information on new tourist attractions can be found in the offices of the Tourist Board of the Municipality of Mljet and the information centers of the National Park Mljet or downloaded in electronic form attached. “Paths of the past” Attachment: Brochure Mljet – a mystical oasis

The Wellcome trustees’ report said: “Tactically, we viewed the risk to sterling from the referendum to be asymmetric and reduced our sterling exposure (including hedges) to an all-time low ahead of the vote. Sterling’s subsequent depreciation and the generally steady performance in underlying assets enabled us to record a sterling return in the year of 19%.”At end-September, 58.1% of Wellcome’s portfolio was denominated in US dollars, compared with 23.8% in sterling.Asian currencies made up 8.5%, with a further 4.1% in European currencies.The report said: “Our global diversification enabled us take advantage of the sharp depreciation of sterling over the year. It also provided the rating agencies with the confidence to maintain our coveted AAA/Aaa (stable) credit rating, even as they were downgrading that of the UK government.”Danny Truell, managing partner of investments at the Wellcome Trust, said: “The portfolio has again performed well in a difficult environment for many investors. The decision to reduce home country bias and to diversify assets and geographical exposure has borne fruit.“Although future investment returns are unlikely to match recent experience, we remain confident the portfolio should generate sufficient cash flows to insulate the trust from potentially more difficult conditions.”In terms of performance by individual asset classes, public equities – 50.5% of the portfolio at end-September – were led by growth markets with a 29.9% return, followed by global (28.6%) and developed world equities (24.6%).But all these were lower than the MSCI AC World return of 31.3%.In their report, the trustees criticised the “poor” performance of their outsourced public equity strategies.The report said: “Of our 11 external equity managers, with £4.2bn of our investments, eight underperformed against their reference benchmarks, in each case by at least 5%. Although nine of the 11 are still ahead of their benchmarks over five years, warning bells are sounding.”And it said active public equity managers, particularly in the US and Europe, were confronting three powerful and correlated headwinds: a long-term structural bias against mega-cap companies, performance measurement periods that engender pro-cyclical behaviour; and the accelerating shift from active to passive index management.Over the past decade, the trust has reduced its external active management in global and developed market mandates from 85% to around 20% of its public market exposure.In contrast, all five of its external managers for emerging market equities have beaten their benchmark since inception.The best-performing class for private equity – which as a whole makes up 25.2% of the trust’s portfolio – was large buyouts, with a 34.9% sterling return (though the US dollar return was 15.6%); mid buyouts and specialist returned 25.7% and 24.9%, respectively, compared with an MSCI AC World return of 31.3%.But hedge funds made -0.7% over the period, the only strategy boasting positive results being directional funds, with a 0.8% return.Hedge fund exposure has been more than halved from 23% in 2008 to 10.7% in 2016, with some funds sold to increase exposure to equities.Wellcome’s real estate portfolio failed to repeat the double-digit returns of the previous year, with a 3.2% return for the year to end-September: 3.6% for residential, and 0.5% for non-residential, portfolios.Residential property – concentrated in prime central London units – makes up just over half the allocation.Over the year, the allocation to property fell by 2.7%, to 10.2% of the overall portfolio.The report said: “Uncertainty induced by the impact of Brexit and downward pressure on London super-prime residential activity created by higher taxes caused headwinds for our predominantly UK property interests. Active management enabled us to record modest positive returns.“Uncertainty about Brexit might well create further attractive opportunities for our patient long-term capital.” A tactical bet on the outcome of the UK’s EU referendum helped push investment returns at the Wellcome Trust – the UK’s largest charity – to 18.8% for the year to 30 September, compared with 6.1% for the previous year, and taking its investment assets to £20.9bn (€24.9bn).The results take the annualised return over three years to 13.3% per annum, and over five years to 14% per annum.While not predicting the “surprise result” of the EU referendum, the trust said it had already diversified its portfolio globally over the past decade to reduce significantly any home country bias.But this policy was intensified in the run-up to last June’s vote.

In-form midfielder Dele Alli scored two near-identical headers as Tottenham Hotspur beat Chelsea 2-0 in London last night to torpedo the Premier League leaders’ hopes of a record 14th consecutive victory.Chelsea were bidding to become the first team to win 14 successive games within the same English top-flight season, but Alli’s goals, both set up by Christian Eriksen, brought them down to earth.“We were competitive against a team in very good form, one of the best in Europe, and we feel very proud and pleased because the performance was very solid,” said Spurs manager Mauricio Pochettino. Antonio Conte’s Chelsea must content themselves with having equalled Arsenal’s season record of 13 wins in a row from 2001-02 and they remain five points clear of second-place Liverpool.But the end of their winning streak will give hope to their pursuers, not least Tottenham, who rose above Manchester City and Arsenal to third place in the table, seven points below the leaders.“It is a pity to stop this run, but Tottenham is a good team, a really strong team and I think is for sure one of the teams that can fight for the title until the end,” Conte told Sky Sports.“My team are top of the table because we are working a lot. This league is very tough and it is important to continue to work.”Alli, 20, has now scored braces in three successive games and his latest double allowed Pochettino’s men to register a fifth win in a row — their best such run in nearly a year.It also enabled Spurs to claim a measure of revenge, both for their 2-1 defeat at Chelsea in November and the fiery 2-2 draw at Stamford Bridge last May that ended their title challenge.Pochettino, meanwhile, could celebrate his 150th Premier League game as a manager with a deeply satisfying victory.“We are in a good position, third in the table,” he said. “But it is a long way to finish the season.”Whereas Spurs had gone with four at the back in November’s 2-1 loss at the Bridge, here they effectively matched Chelsea’s 3-4-3 shape, which made for an attritional first half at White Hart Lane.Spurs saw most of the ball, their wing-backs Kyle Walker and Danny Rose carrying the fight, but they struggled to pick holes in Chelsea’s rearguard and the visitors posed a threat on the break.In the fifth minute, Nemanja Matic’s lofted pass over Spurs’ right-sided centre-back Eric Dier found Eden Hazard in ample space, only for the Belgian to shoot narrowly wide with his left foot.Victor Wanyama and Eriksen sent low efforts wide from range for Spurs and when the hosts finally got in behind, Dier ghosting in to meet Rose’s deep free-kick, Thibaut Courtois was on hand to save.But in first-half injury time, Spurs struck, Eriksen shaping a cross into the box from the right and Alli, hitherto close to anonymous, leaping to plant a glorious header in the top-right corner.It was the England midfielder’s sixth goal in four games and within nine minutes of kick-off in the second half, he would have a seventh.Urged on by a typically animated Conte, Chelsea flew out of the traps, Diego Costa testing Hugo Lloris with a skidding strike and Hazard nodding Marcos Alonso’s header wide from point-blank range.The celebrations, though, were Tottenham’s thanks to a near carbon copy of their first goal, Eriksen swinging a cross to the back post and Alli outleaping Victor Moses and Cesar Azpilicueta to head home.Conte made three bold changes, sending on Willian, Cesc Fabregas and Michy Batshuayi for Marcos Alonso, N’Golo Kante and Moses, with Pedro Rodriguez moving to a left wing-back role.Share this:FacebookRedditTwitterPrintPinterestEmailWhatsAppSkypeLinkedInTumblrPocketTelegram
Ollie Jung | Daily TrojanIt’s a simple fact that most sports fans are hopeless optimists. Dodger Stadium has been packed to the brim for the opening two games of the World Series in support of a team that last won it all during the Reagan administration. Tens of thousands of people pack the Coliseum week-in, week-out every year despite more than a decade passing since the Trojans’ last national title. Optimism is sports’ lifeblood, and even the most jaded fan has the slightest sliver of it.But for the last week, it has felt like Notre Dame bled every last drop of that optimism during last Saturday’s massacre in South Bend.Like many others, I have been almost blindly bullish when it comes to these Trojans since January. Ignoring all the warning signs for a far more challenging, target-on-your-back season to come, I basked in the Rose Bowl glory, completely convinced that the trifecta was coming in 2017: a Pac-12 championship, another victory in Pasadena and a return to the national championship.Nearly 11 months later, and here we are. USC is still a frontrunner for the conference crown, but with the ultimate prize out of reach, the remainder of the season will only determine what sort of silver lining the program can take into next fall. Some have called for head coach Clay Helton to be fired, and others have declared redshirt sophomore quarterback Sam Darnold a bust.I instinctively want to defend the Trojans. I want to point to Helton’s strong 22-9 record at the helm and remind everyone of what Darnold did against Texas and Utah this year. But there’s not much I can say that doesn’t ring hollow after USC last Saturday. I feel like a flat-earther: The facts are staring me in the face, but I’ve somehow talked myself into something different.I’ve died on worse hills, though (I was convinced Blake Bortles would be a good NFL quarterback for far longer than I am proud of). What really scares me is that the nightmare may not be over. The Trojans are traveling on back-to-back weeks coming off arguably their two most taxing games this season. And like the losses at Washington State and Notre Dame, Arizona State is expected to have a sold-out crowd at its back. The Sun Devils beat then-No. 5 Washington and Utah in their last two games, and they will look to catapult themselves into the thick of the Pac-12 South race with an upset over USC.After ASU, Arizona arrives at the Coliseum, and the Wildcats could be coming off a home win over Washington State, riding speedster quarterback Khalil Tate. Tate put up nearly 400 yards against UCLA — 148 through the air and 230 on the ground with three total touchdowns. After facing Arizona, the Trojans go to Colorado, then return home to face UCLA to wrap up the regular season. How great can you feel about any of those games? My greatest fear is when all is said and done this season, USC will have had a seven- or eight-win season with a trip to the Holiday Bowl — no different from the days of Steve Sarkisian and Cody Kessler.There’s no bright spot to look to anymore. Darnold hasn’t hit his peak all season. The rushing attack that opened the year so promisingly has been derailed thanks to injuries. Special teams coughed up the ball and left easy points on the board in recent weeks. An intimidating defense that ranks among the nation’s best in forced turnovers got dominated in South Bend. Week-to-week improvement hasn’t been this team’s forte, so it wouldn’t be surprising to see another error-filled night in Tempe on Saturday.It’s hard for me to believe that Helton and company will suddenly clean things up to win the Pac-12, which means that after all the fanfare, it’s just another lost season. I would say that the Trojans finally stole away all my optimism, but there is just a bit left — the hope that they will prove me wrong and win out … and win it all next year.Ollie Jung is a senior majoring in print and digital journalism.
