first_imgShare This!With miles of walking, heat, and humidity, Walt Disney World is the kind of vacation that you need to get some rest to enjoy. The paradox has always been that to get the most for your money, you’ve got to arrive early and stay late.Now, with the Animal Kingdom’s longer evening hours and Hollywood Studios’ construction closures, it’s possible to sleep in and still see everything in those parks in one day. That means you can alternate full days in Epcot and the Magic Kingdom with relaxed, late starts at the others – even on short trips. A sample 4-day, long weekend might look like this:Full day at Magic KingdomSleep late and visit the Studios or Animal KingdomFull day at EpcotSleep late and visit the park you’ve not yet seenThe key to those sleep-in days is setting up a touring plan with the right FastPass+ choices and times.

first_imgShare This!There’s something about the magic of a Disney vacation–that extra little pixie dust that makes a trip go from good to great. The idea behind Adventures by Disney is what if you could take that vacation experience that you have when visiting the parks and take it with you as you travel to destinations around the world. Of course all magic comes with a price, dearie. Adventures by Disney trips typically cost more than similar trips offered by other tour group companies, and far more than planning a budget-conscious trip on your own. The marketing for these trips does make them look impressive, and I’ve rarely heard anyone have anything negative to say about the actual trip. Is it something that many people have done, however? Last week, we asked you:Have you ever taken an Adventures by Disney trip?Here’s your results:Yes (55 votes, 5%)The variety of Adventures by Disney trips is impressive. The activities you can do on them are amazing. You can cruise down the major rivers of Europe, or go dog sledding in Wyoming. You can look for wildlife while hiking in the Galapagos Islands, or on safari in South Africa, or snorkeling in the Great Barrier Reef off Australia’s coast. You can take a vacation without a Disney park experience, or you can set up your vacation to make a stop at Disneyland, Hong Kong Disneyland, Shanghai Disneyland, Walt Disney World, or Disneyland Paris. While the trips are more expensive than if you booked events on your own, Disney often adds little extras to make the trips memorable. The guides on the trips come with a wealth of knowledge that you may not get with another tour company or on your own. Even better, these trips tend to have minimal outside costs. The price you see, aside from transportation to the start of your trip and home at the end, includes most of your activities, meals, and lodging. Many people who responded yes to this question mentioned that they’ve been on more than one Adventures by Disney trip. It may require eating instant noodles when you get home and rolling pennies for the next one, but people seem to want to keep coming back for more.No (1,031 votes, 95%)At the end of the day, no amount of marketing and hype can hide the fact that these trips are expensive. Even a short, three-night Disneyland Adventures by Disney trip will set you back more than $2,000 per person. Different trips can run $5,000 or more per person–the one to China that I’ve been dreaming of is more than $9,000. (And that doesn’t include the airfare to get to and from your destination.) Some people mentioned that this is a Bucket List or Powerball dream–if the money appeared, they’d go in a heartbeat. Others have a hard time justifying the price even if money was no object. In the end, it takes a lot to make the leap to plunk down the money on this. It is no surprise that most people who responded haven’t taken one. (You can count me in the number of people who haven’t been parted with my money for this trip yet. Maybe when I’m an empty nester?)So there you have it–this week’s results. Next week’s question is live on Twitter and on the blog here. In the meantime, if you were given one wish from Genie, but you had to use it to take an Adventures by Disney trip, which one would you wish for?last_img read more

first_img18 January 2008South Africans Alex Harris and Sibusiso Vilane made history on Thursday when they became the first South African team to walk unassisted to the South Pole.The duo set out on their epic 65-day journey on 10 November, dragging 130-kilogram sleds almost 1200 kilometres across some of the most hostile terrain on the planet.Antarctica generates much of the bad weather in the southern hemisphere, and storms there can be fierce. Temperatures range from an ambient of about -8 degrees to about -40 degrees Celsius.They completed their journey without the help of support teams putting out food or rigging up tents, and without using wind power or sled dogs, in what Harris described as “the purest form of getting to the South Pole”.Harris and Vilane are no strangers to extreme feats, with Harris becoming the second South African to summit the highest peak on each of the seven continents, the so-called “seven summits”, in 2005 and Vilane becoming the first black South African to climb Mount Everest, the world’s highest mountain, in 2003.The two men spent almost a year training for the trek, dragging tyres requiring a pulling force of 30-40kg every second day, covering a distance of about 17 kilometres per training session.The trip was premised on covering at least 20 kilometres a day – they carried only an extra five days’ worth of emergency fuel and food – meaning that any mileage lost in a day would have to be made up for, or they would risk running out of supplies.They just made it, taking exactly five more days than planned – one day more and they’d have been running on empty.The physical and mental toughness it took to achieve this is hinted at in some of the extracts from Harris’s trip journal …No painkillers– extracts from Alex Harris’s journal21 November 2007have only covered distance of 45kms so far, but the last 6 days we have been stuck in our tent with high winds, so it is very frustrating23 November 2007finally on the move again. whiteout today so tough going. broke a ski in the wind the other day. did a repair job, just hope it lasts27 November 2007hi. only managed 14km in 8hrs. weather was perfect but it was the toughest day yet. soft snow made pulling desperate. but we finally made it to 81 degrees!01 December 2007at last. day 18 and did 20.48km in 8.5hrs. felt good, weather perfect and snow improving all the time. 42 more days!02 December 2007another good day. day 19. did 19.4km. my heel is starting to act up. there is a monster bank of clouds rolling in from the east.04 December 2007day 21. i battled today. heel burning like a hot poker. trying different things. sibu is fine11 December 2007day 28. last two days have been desperate conditions. zero vizibility and thick snow. only managed 15km today. heaviest the sleds have felt!13 December 2007this place deprives us of the luxury of nightime but the gloom of the day robs us of the light. instead we move through a grey twilight that knows not dawn nor dusk. it is fit for neither the living nor the dead. battled for 10hrs in the same conditions just for 15km04 January 2008day 52. feel exhausted. did 22.3km but getting colder measured -25.9 in my pocket! done 800km12 January 2008day 60 comes at last. perfect weather. still -22. did 25.4km in 10 hrs. tomorrow its on to emergency rations some juicy tidbits not mentioned before for fear of freaking the folks out. in that very windy spell in the first week, i got frostbite on my inside left thigh, about the size of my hand. not serious though as there is nothing to freeze solid and fall off. unless it was higher up my leg! anyway i have had to doctor it every day and make sure it doesnt go septic. but it is finally healing and forming scabs.14 January 2008day 62. mon 14th. gloomy day but still did 25.4km. countdown! 3 more days. 67km. unbelieveable!

Nigel Portwood, chief executive of Oxford University Press, which publishes the OED, told the London Sunday Times that dictionaries sales have been falling off at a rate greater than 10% a year for the last few years. So the next edition may be online only. Such a move might be financially reasonable. After all, the current online edition gets two million hits monthly at $400 per user, and more people are favoring compact, universally-retrievable sources of information. But is finance all we should consider? Over at GigaOm, Matthew Ingram asks if we should care. His response, if I’m reading him right, is yes. I yearned for an opportunity to disagree, dramatically, just pro forma. But I can’t. I’ll go into a bit more detail on why a “hardcopy” of the dictionary (I favor the neo-logism, “book”) is still desirable. The idea of small, lightweight, online, retrievable sources of reference materials is fantastic. I use Dictionary.com more than I use my Websters. (Though Websters gets money either way.) So why not the OED? After all, the twenty-volume mega-book is, at almost $1,600 hellishly expensive and, if you’re sub-Ferrigno, immovable. Because while some books are repositories of information, others are experiences. Although the OED is not a narrative, not scripture, not poetry, it is, nonetheless, transportive. The idea of flipping from one entry to another, following a line of inquiry (especially etymological inquiry) from one page to another, even one volume to another, is a sensual experience. I don’t mean it’s sexy (it is), but rather that it’s an experience that encompasses sight, sound and touch and even hearing (the rustle of pages, the thump of the volume hitting the desk) to create the context for comprehension. I agree with Matthew that it doesn’t need to be a commercial production, with loads of books run out and sent by plane and truck to book stores. It may become something of a bespoke tradition – created at user request. Although the Oxford University Press said it hadn’t made a hard-and-fast decision as to whether they’d print again (the next edition probably won’t be ready for a decade), they should make a hard-and-fast decision never to stop printing, even if they have to change the way they print. If scifi has been in some way a guide to our future, let’s remember that Picard read manifests on a PADD but Shakespeare in a book; and further, each new technology does not push all previous technologies out. Nor should it. So come on, Nigel. Make a commitment. Give us that sweet must of a real book when we need the experience of language, not just the data. What do you think? Does the Book matter, or is it only a vehicle for the experience of reading? For more discussion of the online reading experience, read Richard MacManus’s posts where he examines the pros and cons; and mine, where I ask whether e-books are the new paperbacks. last_img read more

first_imgMONTEGO BAY – In a time when several schools are under pressure for not performing up to par, the Corinaldi Avenue Primary in St. James is making positive strides both locally and internationally.The school recently copped first and second places in the 2013 World Plumbing Day International Poster Competition which is staged by the United States based World Plumbing Council. The day is observed on March 11 annually.The 2013 staging of the Poster competition had entries from elementary/primary schools from around the world, including countries such as the United Kingdom, Scotland, Canada, Trinidad and Tobago, the USA and Jamaica.In the end, Andrew Malcolm and Nakelia Humphrey, both 5th grade students at the Corinaldi Avenue Primary, took  first and second place respectively, with Liana Ellis, a 4th grader at Dunross Primary School in St. James, Trinidad, taking the third place spot.For their winning pieces, Andrew Malcolm received US$100 for himself and US$1,000 for his school; while Nakelia Humphrey received US$50 for herself and US$500 for her school, which will receive in total US$1,500.The school’s participation in the competition came about when Grade Six Teacher Donette Salmon, saw the information on the Internet and along with Grade Three Teacher, Dane Julius, decided to have two students enter.“We have very talented students here at Corinaldi, and so we decided that Nakelia Humphrey and Andrew Malcolm would be good choices (to do entries), seeing that they have more experience in entering poster competitions and doing very well at it,” Ms Salmon told JIS News.Mr. Julius informed this is not the first poster competition that the school has won, and their achievements have spanned both international and local competitions over the years.Both teachers are overjoyed by the results in the World Plumbing Day International Poster Competition. “(It is) not only that we won, but we gained the two top places in the competition, which is a first for the competition itself, so we were overwhelmed by it,” Ms Salmon said.The students, Andrew and Nakelia, are equally excited at finishing in the top two.With a student population of approximately 1600, Principal, Cynthia Munroe, told JIS News, that she and the entire school population felt very excited to have outdone the many schools from around the world that entered the competition.“We had done it before and we knew that we could do it again,” she said, while praising the Art Teacher at the institution for the continued success of the students.An official function was held at the school to highlight the achievement of Andrew and Nakelia, at which they received both their World Plumbing Council prize, as well as special prizes from the school.Mrs. Munroe credits the continued high levels of achievement of the Corinaldi Avenue Primary School to a shared vision between principal and staff.“Our teachers are highly motivated and committed, and they transmit this commitment and motivation to our students; and so our students know that when they get out there they have to excel, they want to achieve at the highest,” she explains.She further reveals that this feeling and principle is applied throughout the school in all areas.last_img read more

Barry Bonds is back in baseball. The Miami Marlins announced Friday that Bonds will become their hitting coach, joining new manager Don Mattingly’s staff.1Since retiring, Bonds has worked as a spring-training guest instructor for the San Francisco Giants, but not on a full-time basis. So now we’ll get to obsessively analyze Bonds’ proportions all over again, this time in arguably the majors’ worst uniform.Bonds is a lightning rod because of his role in MLB’s steroid era, but I’m not here to re-litigate how much he cheated or what his punishment should be. The guy was pretty terrific at hitting a baseball long before we knew what BALCO was.My question is simple: Does a good hitter make for a good hitting coach?Not necessarily.To find out, I looked at every hitting coach going back to 19732The year the designated hitter was introduced. using data from Retrosheet.org, and for those who played in MLB, I gathered their Weighted Runs Created Plus (wRC+, a per-plate appearance measure of offensive production that we’re quite fond of at FiveThirtyEight) and the number of wins above replacement (WAR) that can be attributed to their offensive contributions.3For sticklers, this means I removed both positional defense and the overall position adjustment from a player’s WAR. But I did leave baserunning in offensive WAR, as is the custom for the statistic, even though that aspect of the game is often managed by instructors other than the hitting coach.But how does one go about quantifying coaching performance? It’s a complex question that I’ve struggled with over the years. One simple way to judge a hitting coach’s effectiveness is how well his hitters outperformed their expectations. To that end, I used a historical database of Marcel projections — named for the pet monkey from the show “Friends” because they’re so basic a monkey could compute them — and measured the degree to which a hitting coach’s pupils performed better in the batter’s box (according to Weighted On-Base Average, or wOBA) than they were projected to.Armed with all this information, we can see the (non-)relationship between a hitter’s offense and his coaching talents. Whether we make the comparison using the hitting coach’s career WAR, as in the chart above, or using a weighted average of his lifetime wRC+, the correlation between hitting well and coaching others to do the same is effectively nonexistent.While Bonds may have been second only to Babe Ruth among career hitters — ignoring steroids — we have no idea what that means for Giancarlo Stanton, Dee Gordon and the rest of the Marlins hitters. So while the thought of Stanton becoming even more Bonds-like has pitchers everywhere reconsidering their chosen profession, it’s still anyone’s guess whether Bonds will be able to communicate to others just what drove his preternatural plate discipline and freakishly fast reflexes at the plate. read more

first_img More information: A preprint of the article is available at arxiv.org/abs/0909.2445v2 . (PhysOrg.com) — Laboratory experiments in the last few decades have shown that some things can appear to move faster than light without contradicting Einstein’s special theory of relativity, but now astrophysicists have seen real examples of superluminal speeds in the form of radio pulses from a pulsar. Superluminal, or faster than light, speeds are associated with anomalous dispersion, which is a process in which the refractive index of a medium increases with the wavelength of light passing through it. If a light pulse (consisting of a group of light waves at different wavelengths) passes through such a medium, the group velocity of the pulse can increase to a velocity greater than any of the waves within the pulse, but the energy of the pulse still travels at the speed of light, which means information is transmitted in accordance with Einstein’s theory.Astrophysicists, led by Frederick Jenet of the University of Texas at Brownsville, have been monitoring a pulsar, PSR B1937+21, which is about 10,000 light years from Earth. They used the Arecibo Observatory in Puerto Rico to obtain radio data over three days at 1420.4 MHz with a bandwidth of 1.5 MHz. They found that pulses closer to the center arrived earlier than the normal timing, which suggests they had travelled faster than the speed of light.A pulsar is a neutron star that is spinning rapidly and emitting a rotating beam of radio radiation as it spins, which is observed on Earth at regular intervals rather like light from a lighthouse. The pulses of radiation can be affected by several factors as they travel through the interstellar medium (ISM). Their polarization can be rotated if they pass through a magnetic field, for example, and they can be scattered if they encounter free electrons, and can be absorbed by neutral hydrogen in the ISM. Jenet and his colleagues think anomalous dispersion also affects the pulses.According to Jenet and colleagues, the pulses from the pulsar traveled through a cloud of neutral hydrogen, which has a resonance of 1420.4 MHz — the exact center of the bandwidth studied. Passing through the cloud caused anomalous dispersion that resulted in a superluminal group velocity, and pulses with frequencies closest to the resonance frequency arrived earlier than other pulses. The scientists believe the pulses appear to travel faster than light because of an “interplay between the time scales present in the pulse and the time scales present in the medium.” The faster-than-light pulses do not violate Einstein’s theory because technically the pulse carries no information. The effect has been known in laboratory experiments, but these observations were the first in an astrophysical context.The findings, to be published in the Astrophysical Journal, could help astronomers gain a more complete understanding of the composition of space in the regions between stars, and in particular the properties of neutral hydrogen clouds in our galaxy.
