    The Largest Arctic Expedition Ever Is Freezing Itself in the Ice, Here’s Why

    December 7, 2019


    Last month, hundreds of researchers from all
    over the world started the largest-ever Arctic expedition aboard a ship just over 500 kilometers
    from the North Pole. What makes this project even more unique is that the entire ship will
    be frozen, embedded in sea ice for an entire year. So it begs the question, why are they
    even doing this? For starters, it’s the most ambitious climate
    change expedition ever attempted of the Arctic. The Multidisciplinary Drifting Observatory
    for the Study of Arctic Climate, or MOSAiC, will be studying the effects of a warming
    climate on the central Arctic’s atmosphere, ice, ocean, and ecosystems. By drifting with
    the ice for a year, the team will be able to collect the necessary information to create
    better climate models to help inform what the Arctic will look like as it continues
    to warm. “For us, there are a number of knowns and
    unknowns. The knowns are that we are going out to the Arctic with all kinds of instrumentation,
    more than there’s ever been on a ship before out in the Arctic. We know we’re going to
    get a lot of first measurements of many types of data. It’s our first look at things like winter time aerosol properties, first look at like scanning cloud radar measurements. Then there’s a lot of unknowns, and those are really related to the conditions that we’re going to encounter there.
    So the sea ice, we’re really at the mercy of the sea ice.”
    When they arrived at their destination, the German icebreaker, called Polarstern, chose
    the perfect ice floe to attach itself to, a crucial part of this mission since the ice
    needs to withstand the weight of heavy instruments. This ice floe will serve as the so-called
    ‘ice camp’ for the expedition’s experiments and a landing strip for research planes. Once
    frozen in place, the scientists will have to set up camp quickly, as winter is coming
    for roughly 150 days, and come November, they’ll be operating in complete darkness.
    And that is when nature takes over. Drifting at about 7 km per day, the frozen ship hopes
    to follow the path taken by ice floes along a phenomenon called the transpolar drift.
    This path will allow the ship to drift from the pole and move south towards the Fram Strait,
    located east of Greenland, where the expedition will come to a close.
    The ship will have about 100 people aboard at a time. It will be frozen in place, in complete darkness, while research continues. And the Polarstern will be at the
    center of most of MOSAiC’s research, containing laboratories and technical equipment onboard
    to take measurements and observe the environment. At the base camp, experiments will be divided
    into different hubs like ROV City, which will use remotely operated vehicles to observe
    marine organisms and collect water samples from beneath the ice. Or MET city which will
    measure the composition of the atmosphere using tethered balloons, which will continuously
    float 2 km above the camp. On top of all the research, the Polarstern will have a distributed
    network of observational sites operating within a 50 km radius of the ship, which will be
    equipped with remote and autonomous sensors to collect additional oceanic, ice, and atmospheric
    data. “At the end of our year in the Arctic, we’re going to learn a lot about the new Arctic system. With thinner sea ice, with the interactions that are
    adapting themselves to the change, we’re going to learn a lot about how the Arctic is manifesting.”
    And in the spirit of collaboration, the researchers will upload their information to a database,
    making it accessible to their hundreds of MOSAiC colleagues worldwide. So we’ll just
    have to wait and see the anticipated results of this expedition that could help us better
    map the future of our planet. Are there any other scientific expeditions
    that you’d like to see us cover, let us know down in the comments. Make sure to subscribe

    How to make a wool felt picture: beach sea

    December 5, 2019


    Hi I’m Aannsha Jones. Thank you for visiting. In this video you can learn how to make it felt painting and lay out the wool in a great design, so with that said let’s get started. Making felt paintings and wall hangings is fun! I began as an artist using acrylics and painting murals. I wanted to see what could be achieved with felt. Here are some of my felt paintings. I think you’ll agree you can create anything you can imagine. Today we’re making a simple painting with simple design layout, but from here you can explore your own style. All materials for this project are listed below. Start by laying the first of 4 layers. I use white wool as it makes a nice fresh base. Layers of wool blend as they felt so for the second layer, lay blocks of color as a background for your finished painting. So orange and yellow for the sand and light blue for the ocean. Lay these rovings at right angles to the first layer. The third layer will bring more variety of shades which will give the finished felt painting more depth. If it helps look at a photo of the beach to see where the sand is lighter and where the ocean looks darker. Here I’m adding different sand shades, getting lighter where the waves meet the sand. Again the tops are laid out at right angles to the second layer. I’m still using light blue for the ocean because I’ll use a mixed roving for the waves detail in the final layer. Pat it down and make sure it is even thickness. I’m using two mixed rovings for the waves: dark blues and ocean blues & greens. The white in each roving is silk which gives it lustre, like shiny water. As you can see I’m teasing out the shades of blues and see greens leaving pale blue showing through and this creates the look of waves. Where the waves meet the shore, I’m using white roving to create the white wavy foam, then I had more dark blue to create shadow and this gives the waves depth. Next I use variegated yarn and roll it up to create the effect when it’s felted of coral and shells. Once I’ve placed these in position I use a little wool roving the same color as the sand to place over the yarn and this helps it to felt well into the painting. To create more light in the waves and on the beach I add hand dyed silk rovings and these catch the light and and add shine. I balance the dark of the ocean with a stronger burnt orange on the sand at the base of the painting. Next I add some dimensional wool and gives really gives a great ripple effect to the sand. Finally I add wool nepps to the crest of the waves to give more of a frothy look the foam. Nepps don’t blend easily as they’re already pretty much pre-felted so these need white rovings over the top to help them felt. Now ready to felt, put down netting and wet the wool right through. Carefully rub soap over the wool and begin rubbing gently so as not to disturb the design underneath. I will quickly show most of the felting process here but for full details, materials and an explanation on how to make felt, please follow the link provided. And the pinch test shows it’s mostly ready for the next stage except one little detail and I rub that the bubble wrap. Now onto rolling around the pool noodle The video: How to make felt – tells you how long to roll and how many times to turn your work to get even shrinkage. Now for the following stage: rubbing the felt and dipping in soapy water and then more rubbing. It’s ready when you achieve that lovely recognizable textured finish. Then you need to rinse all the soap out. Add 2 tsp vinegar to the final rinse and make sure the wool soaks it up. Leave it to rest in the vinegar water while you tidy up. Squeeze out the excess water gently then towel dry. Pull into shape and there’s your beautiful finished felt painting. And here it is hanging on the line. I love the colours! And here is dry.

    Why Does Fish Flake?

    Why Does Fish Flake?

    December 3, 2019


    {♫Intro♫} Whether you like it in your tacos, fried with
    chips, or on top of rice, fish can be delicious. But if you’ve ever eaten it, you probably
    noticed how flaky fish can be. Poke at it with your fork and it just falls
    apart — no knife required. Other meats, like beef or pork, don’t break
    up into those little chunks, either. It turns out that the same muscle physiology
    that helps fish get around underwater ultimately means better tacos for us. Fish bodies are ridiculously muscular compared
    to land animals. Cows may look like tanks made of beef, but muscle makes up less than half of their
    body mass, while in salmon or tuna it can be over 60%. And almost all of that is fast-twitch muscle,
    which is exactly what it sounds like: muscle that contracts quickly and forcefully. That’s a pretty handy adaptation if you
    need to quickly swim away from predators. In contrast, land mammals tend to have a much
    larger proportion of slow-twitch muscle fibers to support their bodies during hours of standing
    and grazing. But even when land animal tissues have lots
    of fast-twitch muscle — like a turkey breast — it doesn’t flake
    like salmon. It shreds. That’s because land animals organize their
    muscle fibers into fascicles, long bundles wrapped in connective tissue. Fish instead have overlapping layers called
    myomeres, W-shaped segments that interlock with each
    other and allow the fish to bend its whole body side to side as it
    swims. It’s these layers that create the chunks
    that break apart when you poke them with a fork. Myomeres are wrapped up a bit differently,
    too. All animal muscle contains some connective
    tissue called collagen, but bite for bite, fish meat has less collagen
    than its bovine counterparts. Collagen binds myomeres together, and you
    can sometimes see it as white stripes in a cut of fish. Fish collagen also breaks down at a much lower
    temperature, compared to that of land animals, due to different
    amounts of an amino acid called hydroxyproline. This is fine when the fish are in their comparatively
    chilly habitat, but makes a big difference in your frying
    pan. All that collagen becomes gelatinous when
    heated, which causes it fall apart more easily. So, not only is fish muscle organized into
    chunks on the animal, but the connective tissue it’s wrapped in
    disintegrates more easily before it gets to our forks. If all this makes you look at fish a little
    differently, allow me to recommend the fried version. You can’t see the flakes and it goes great
    with sriracha. Thanks for watching this episode of SciShow, and a huge thanks to our President of Space
    Matthew Brant for your support. If you’re interested in joining our community

    Golden Rules of Kayak Fishing

    December 3, 2019


    This episode of kayak fishing tales is
    brought to you by the ACA improving the paddle sports experience for over a
    century learn more at AmericanCanoe.org ♪ [Opening Theme] ♪ The golden rules of kayak fishing are a
    set of basic rules that all kayak anglers should follow. among other things, these rules will help
    keep you safe on the water, and they’ll enhance both yours, and other angler’s outdoor experiences. The first rule is a very simple, but
    valuable one. always wear a life jacket the water. Think of your life jacket like a seatbelt in your vehicle chances are you won’t need it, but
    accidents happen when you least expect them to, and wearing a life jacket can
    save your life. the best life jackets for kayak fishing
    are ones that are designed specifically for the job, because they’re comfortable
    to wear, they give your arms full range of motion for paddling and casting, and
    they have lots of pockets for fishing tackle and gear that you want quick
    access to. The second rule is to leave no trace, which means leaving wherever you launch and fish, cleaner than it was when you got there not only is it important to respect the
    environment, but keeping our fishing grounds clean will also help keep access
    to launch spots open. The third golden rule is to invest some time and learning the ‘kayaking’ part of the game. Although fishing kayaks are stable and
    comfortable enough for most anyone to hop onto them and start catching fish,
    learning to become a better paddler WILL make you a better angler, and on top of
    that, it will keep you safer on the water. Rule number four, is simply to know the
    rules and regulations of the waters you’re fishing. the fifth and final golden rule, is to
    share your knowledge with others. one of the greatest things about the
    kayak fishing community, is that it’s a very friendly and open community, and
    most kayak anglers are happy to share the lessons or tricks they’ve learned, which enhances the outdoor experience for everyone. well I hope you found this video helpful, and
    if you did please subscribe to the Kayak Fishing Tales youtube channel for lots
    more tips and tricks. until next time, I’m Jeff Herman hoping you
    have a safe and successful kayak fishing trip.

    The Puppies Go To The Beach

    The Puppies Go To The Beach

    December 3, 2019


    (light cheerful music) – [Narrator] The service dogs in training from Doggy Do Good have a big day ahead of them. It’s beach day! The sun, the surf, and boundless distractions that could cause any of these dogs to flunk out of Service Dog School. This is Puppy Prep. ^(light cheerful music) None of the pups are more excited to smell that ocean air ^than eight-month-old Golden Retriever, Luke. He’s been hanging out by the beach since he was only a couple months old. ^His half-sister, Remmy, is also excited, maybe too excited. It’s all right for her to take a second and adjust to the new sights and smells, but when it comes time for work, Remmy’s going to need to focus. For these puppies, the first order of business at any new location is to sample the local grass. While they’re not supposed to chew on the foliage, it’s easy for the pups to sneak a bite when the trainers have their backs turned. And the trainers turn their back frequently. Having this many puppies around draws attention, and people are excited to learn about the service dogs. But Nelly and Remmy are taking this chance to mess around. (dogs barking) The dogs aren’t supposed to go on the sand after 10:00, and while special exception can be made for service animals, there’s no shortage of other activities by the ocean, like the playground. The playground offers a multitude of different surfaces, sounds, and experiences. All of this builds confidence, getting the puppies ready for anything. ^First one up, six-month-old Chocolate Lab, Benelli. Climbing on rocks and walking on sand may appear simple, but it’s actually building the puppy’s comfort on a variety of surfaces. Wherever Benelli goes, she needs to be focused not on where she’s standing but on what her owner may need. – Good girl. – [Narrator] After breezing through the different surfaces, it’s time for something that will really disorient her. – Good girl. – [Narrator] The slide. While Benelli’s future owners may never actually take her down a slide, it’s important she has confidence to handle all kinds of new experiences. At first, she’s nervous, but with some coaxing and the promise of treat… – Good girl! – [Narrator] …even a puppy like Benelli can find her courage. Now back on firm land, the trainer is sure to praise Benelli up, building a connection in the puppy’s mind between bravery and reward. Fresh off the excitement of the slide, Trainer Paul tosses his keys to ensure Benelli still knows it’s work time. – Good, get it. – [Narrator] And she happily does her job. – Benelli, great, get it. Benelli, get it. Good girl. – [Narrator] There’s still one more slide for Benelli to attempt. (dramatic drumbeats) The spiral slide. That is, if she can get up to it. With a bit of a running start… – Benelli, jump. – [Narrator] …she makes the leap. – Good girl. – [Narrator] Her lesson from the other slide has her excited to try this one. Having never seen them before five minutes ago, slides are now simple for the six-month-old Chocolate Lab. – Woo hoo hoo! Good girl!
    Good girl. – [Narrator] Back with the dogs in down stay, ^Karen tries to refocus Remmy. She tries to get the Golden to heel, and focus in, but the eight-month-old won’t settle down. This isn’t good. Remmy’s future owner will count on her, day in and day out. And, it looks like Remmy’s lack of focus is starting to spread. Luke, get back! Come on, Karen’s trying to focus on Remmy. Kaya, are you serious? Come on! – Kaya, no! – [Narrator] All three Goldens have the sillies now, even usually dependable Luke. Kaya has to refocus, and quick. It’s her turn to walk the playground. ^The eight-month-old enjoys jumping on different surfaces. – Good girl! Good girl. Come on, let’s go. – [Narrator] The straight slide. – Good girl! Good girl, Kaya! Good girl! – [Narrator] And when it’s time for the spiral slide, what was a tough jump for Benelli is an easy hop for Kaya. But, what goes up must come down, and Kaya’s confused how that’s supposed to happen. When Sandy, the owner of Doggie Do Good, leads the way, Kaya eventually figures it out. She’s immediately praised for her bravery. – Good girl! Good girl! – [Narrator] A second attempt down the slide… (laughs) Oh, look at you. Oh, no. Good try, Kaya.
    Good try. – Good girl. Good girl, Kaya. – [Narrator] But, what’s important is that Kaya’s conquered her fear, and admirably so. Back in the down stay, it looks like Remy has finally calmed… Oh. Relax, Remmy.
    It’s just a bird. All right.
    Good girl, Remmy. Thank goodness you’re finally starting to show some self-control, otherwise today could have been the day you failed at… Oh no. – [Trainer] Remmy! – [Narrator] Breaking from a down stay to this degree is a bad sign. With Karen working with Kaya, Paul has to leave the dogs to find where Remmy ran off. Even though they’re unsupervised, they don’t dare to break; no one wants the fate that’s about to befall Remmy. Lockdown. Remmy now has to think about what she’s done, and hope it doesn’t mean expulsion. ^Now, it’s Luke’s turn to take a lap around the playground. – Good boy. – [Narrator] His first challenge is the rocking horse. Karen is trying to get Luke to jump over it, in preparation for future awkward spaces. – Stay. – [Narrator] Luke is not having it. – Good boy.
    Jump over it. – [Narrator] He hasn’t had problems of bravery in the past, so this is a new issue. – Over it.
    Nope. Over it.
    Good boy, come on. – [Narrator] Eventually, our hero figures it out. – Good, good! Good boy! – [Narrator] And Karen is sure to reward his courage. – Good job! Good boy, let’s go! – [Narrator] If Luke shows the same hesitation on the slide, then… – Good boy! – [Narrator] …well, nevermind. – Good job, Luke! Good boy! – [Narrator] Looks like after only a couple attempts, he’s already a pro. – Good job!
    Good boy! – [Narrator] Good job, buddy. – Good job. – [Narrator] When Luke returns to down stay, he finds Deacon is still getting used to his harness. He’s not quite sure why he can’t flip all the way over on his back. Paul straightens him out, and it’s back to down stay. ^Okay, Remmy. ^You’ve had a tough day so far, so time to redeem yourself on the playground. First up is the rocking horse that Luke struggled with. – Come on.
    Good girl. Over it. – [Narrator] Just like with her half-brother, it’s a matter of confidence. – Let’s go. – [Narrator] And it suddenly looks like Remmy’s lost most of hers. The culprit? The pirate ship steering wheel. – Just need a second. – [Narrator] Notice how her tail is tucked between her legs? So do the trainers. They’re hyper-aware of the pup’s attitude, and this is a huge signal from Remmy. Karen gets down on Remmy’s level and starts feeding her treats. She pets her and praises her, trying to show Remmy she’s safe. Remmy then has to pass by the wheel several more times, ensuring the dog has confronted her fear. – [Karen] Good girl. – [Narrator] If Karen can get Remmy to sniff the wheel or be still next to it, that’s going to be a great indication that Remmy’s making progress. – Good girl! – [Narrator] Eventually, a sniff. – [Karen] Good job! – [Narrator] And after a few more laps, her tail starts to wag again. Remmy’s done extremely well, and with so much excitement already had on the playground, the slide can wait for another day. ^Back on the grass, the undeniable Mr. Pip ^finds himself in an embarrassing situation. – [Trainer] Mr. Pip. – [Narrator] Because he is by far the worst at down stay, Mr. Pip has to be tied up, to the other dogs. Luke seems confused why he has to babysit, but he doesn’t mind. It gives him something to watch as he snacks on the grass. – [Trainer] Luke, leave it. Luke, release. – [Narrator] Finally, some respect. Unbelievable. Chin up, Mr. Pip. You’re still a hero in our hearts. (Mr. Pip whines) ^Another hero from Doggie Do Good is recent graduate Sammy. Sammy transitioned to his forever family only five months ago, but his bond with handler Bryce has been immediate. Sammy helps Bryce with several diagnoses, including generalized anxiety disorder, ADHD, inflammatory bowel disease, and bipolar disorder. One way Sammy aids Bryce is during Bryce’s regular blood draws. Before going into an appointment, Sammy gives Bryce hugs and pressure, helping to prepare the boy for the anxiety the needles cause. During the draws, Sammy gives Bryce constant pressure to help him feel more comfortable. Sammy knows Bryce isn’t in distress now, but the 18-month-old lab checks in constantly, making sure, if Bryce ever needs him, he’s there. While Bryce’s family had always had animals, at first, they weren’t sure about adding a service dog. The support that Sammy’s provided in only his first few months, however, has made it all worth it. Someday, the puppies in training will have similar bonds with their owners and be just as important to a family as Sammy is. Back with the student pups, it’s time for a long walk on the beach. ^Or at least next to it. ^Remmy’s had a big day, so trainer Paul takes this walk very slow. Whenever Remmy begins to pull away or move in a different direction, the trainer stops. This teaches Remmy to stay focused. During a heel, the puppies need to be paying attention to the handler constantly, not drifting away on their own line. – [Paul] Good girl. – [Narrator] Eventually, Remmy starts to do better. On the stairs, heel is even more difficult for these pups. Dogs want to be on even ground, and prefer bolting up and down steps. The people they’ll someday aid, however, may need help with stairs, so it’s important the puppies learn patience. To end her day, Paul works with Remmy on one of her special abilities: hug. As difficult as the day has been for the young Golden, it’s important to remember that someday she’ll be a huge comfort to a lucky family. It’s going to take work and patience, but it’s clear it’ll be worth it. – Release. Good. – [Narrator] Some dogs can become nervous on the pier, as the spaces between the uneven surfaces can be uncomfortable under their paws. ^Not our Mr. Pip, though. ^He even finds the time to get in some of his best down stay work to date. Good boy, Mr. Pip. As the day winds down, Paul begins ^to test a special skill with Kaya: steady. Steady allows people with mobility issues to put pressure on a dog, to sit down, stand up, or just regain their balance. It’s one of Deacon’s specialties, and might someday be Kaya’s as well. Knowing her eight-month-old joints are still developing, Paul puts only the lightest of pressure over her legs. Once she’s grown, she’ll be able to take much more weight, and may even wear a harness like Deacon. At the end of the day, some dogs took steps forward, while others, steps back. For all these puppies, though, it’s still too soon to tell who will flunk out, and who will graduate Puppy Prep. (light cheerful music)

    How Overnight Shipping Works

    November 25, 2019


    This video was made possible by Squarespace. Build your website for 10% off at
    Squarespace.com/Wendover. Overnight shipping is an absolute masterpiece
    of logistics that happens every single night. It may not be cheap, but you can get a package
    shipped from Miami, Florida on a Monday night to Anchorage, Alaska, by 8:30 AM on
    Tuesday. In fact, you can even ship a package, for
    example, from Edinburgh, Scotland on a Tuesday and have the package arrive in Anchorage,
    Alaska by 9am on Wednesday. The speed and efficiency of these worldwide
    delivery networks is mind-blowing and it all happens while we sleep. The three major consumer courier companies
    are FedEx, DHL, and UPS and each is as impressive as the last. FedEx has more planes than Emirates, Etihad,
    and Qatar Airways combined; DHL delivers to every country in
    the world including North Korea; and UPS flies to
    more than double as many destinations as the largest passenger airline. Each has a global
    network that allows for lightning fast shipping at relatively low prices. Behind all this speed are
    enormous air networks that connect the entire world daily. Each of these three operates hundreds
    of flights nightly, but FedEx is the best example since their operations make them the
    largest cargo airline in the world. They have 650 planes flying to 400 destinations
    carrying 6 million packages every single day and the vast majority
    of these flights operate to or from one of their
    hub airports. FedEx’s hub airports are spread out all
    across the world and serve as sorting points where
    packages are transferred from one plane to another. They has hubs in Singapore, Guangzhou,
    Shanghai, Seoul, Osaka, Anchorage, Oakland, Dallas, Indianapolis, Greensboro, Miami, Newark,
    Toronto, Paris, Cologne, Milan, and Dubai, but the most important hub of all is the one
    in Memphis, Tennessee because that’s their
    SuperHub. Memphis is not a huge city—only about 650,000
    people live there—but the reason FedEx centers their worldwide operations in this
    city is because of it’s location. Memphis is not actually
    in the geographic center of the US as might make sense, but it is central. You see, only about 200
    miles away in Wright County, Missouri is the mean population center of the US. This is the
    average location of every resident in the US meaning that the FedEx SuperHub in Memphis
    is the best location to reach the most people
    in the shortest amount of time. For similar reasons,
    UPS has their equivalent global hub, Worldport, nearby in Louisville, Kentucky. The scale of
    FedEx and UPS’ operations in these relatively small cities is staggering. This is the size of the
    commercial terminal at Memphis Airport while this is the size of FedEx’s Superhub. The
    difference at Louisville airport is even more pronounced where this is the commercial terminal
    and this is UPS’ worldport. You can’t even fly to the west coast non-stop
    on a commercial airline from Louisville and yet UPS flies from this
    small city to five different continents. FedEx’s
    operations in Memphis, meanwhile, make this airport the second busiest cargo airport in
    the world above those of enormous cities like
    Tokyo, Paris, Dubai, Shanghai, and falling short only
    to Hong Kong. How the FedEx superhub really works is that
    every night, about 150 planes fly in from all
    around the world between the hours of 10pm and 1am. Immediately upon arrival, the planes are
    unloaded and their packages are put into the hub’s automated sorting system. Within only 15
    minutes, each package arrives at a staging area for its next flight where it’s loaded
    into containers. Planes therefore can start taking off again
    at 2am and continue to until 4am which means that everywhere in the US can have a
    FedEx plane arriving by 6am, but there are some
    destinations that don’t ship enough packages to need a non-stop flight to Memphis. To get to
    small towns fast, FedEx runs flights in small propeller aircraft from the destinations of
    their larger jets. Presque Isle, Maine, for example, is far too
    small of a town at about 10,000 residents to fill a full-size plane so, every morning,
    once the larger planes from Memphis arrive in
    Manchester, New Hampshire and Portland, Maine, packages bound for Presque Isle are sorted
    into smaller prop planes that continue north. With this system, even small towns like Presque
    Isle get their packages by 9am as every spoke in
    the system essentially functions as a mini-hub. Packages are transferred from planes, to smaller
    planes, to trucks to reach their destination as fast
    as possible. Now, it’s important to note that not every
    FedEx package runs through Memphis. That
    would be incredibly inefficient if a customer wanted to, for example, ship a package from
    Phoenix, Arizona to Seattle, Washington. While only 1,100 miles separate Seattle from
    Phoenix, a routing through Memphis would total over
    3,000 miles and six hours in flight. The package
    would still make it overnight, but FedEx would be wasting fuel carrying that package an extra
    1,900 miles, so that’s why they have secondary hubs. In this case, FedEx’s Oakland hub has
    flights to both Phoenix and Seattle so the package would take a relatively efficient
    1,300 mile routing. Memphis essentially serves as the backup hub
    in case there’s not a more efficient routing. The secondary hubs, such as Oakland, in general
    have flights to destinations that are already served by flights to Memphis, but
    the destinations from Oakland are high demand destinations that will ship enough packages
    solely to the west coast to fill entire planes to
    Oakland. Some destinations, such as Albuquerque, New
    Mexico, ship enough packages to fill entire planes to Memphis, but not enough to
    fill flights to Oakland with west coast bound packages so a package shipped from here to
    the west coast would likely take a rather inefficient
    routing backtracking to Memphis. But FedEx’s most ingenious hub is here in
    Anchorage, Alaska. Anchorage, with fewer
    than 300,000 residents, is home to the forth busiest cargo airport in the world. This is, once
    again, thanks to geography. If you draw a straight line from FedEx’s
    Memphis hub to the one in Osaka, taking into account earth’s curvature,
    it goes directly over Anchorage, Alaska. This
    airport is just the perfect stop-over point for flights from the US to Asia. Now, dozens of cargo
    airlines operate in Anchorage but most of them just use the airport as a refueling and
    crew swap spot. Modern airplanes can fly non-stop from the
    contiguous United States to Asia, but doing so
    requires taking more fuel which requires taking less cargo. It’s just cheaper to stop in Anchorage,
    but FedEx and UPS use the stop for something else—sorting. If FedEx wanted to maintain
    current shipping times without the Anchorage hub, they would likely have to run non-stop
    flights from each of their Asian hubs to each of their
    American hubs, but they just don’t have the
    demand to fill this many planes. Instead, they run flights from their Asian
    hubs to Anchorage then flights from Anchorage many of their
    American hubs. While stopped in Anchorage,
    packages from Asia are processed through customs and sorted to be put on the plane bound
    closest to their destination. This helps cuts down on shipping time and
    cost. Shipping is an incredibly price-sensitive
    business. These courier companies rely on
    enormous contracts with retailers and, when some of these retailers are shipping millions
    of packages per day, every cent matters. In a lot of ways, however, the express shipping
    model is inherently expensive largely because of how
    couriers use their most expensive assets—planes. So much is centered around those few sorting
    hours at the big hubs so FedEx’s planes all have to
    wait around to arrive at the exact right moment. Some FedEx hubs, such as Memphis, do sort
    packages during the day, but the overwhelming majority of their business happens overnight. FedEx’s flight from Memphis to Oklahoma
    City, for example, leaves at 4am and arrives at
    5:20am, but then the plane waits around until 10:10pm to fly back to Memphis. That’s over 17
    hours sitting in Oklahoma City and, on that route, the plane is only flying for about
    two hours per day. Meanwhile, commercial airlines regularly fly
    their planes for more than 12 hours per day meaning they have six times higher aircraft
    utilization. FedEx would never be profitable if they
    bought all new multi-hundred million dollar aircraft to use for mere hours per day, so
    they don’t. Overwhelmingly, FedEx and other cargo airlines
    use old aircraft at the end of their lives. You’ll
    almost never see Airbus a300’s flying for passenger airlines anymore, yet FedEx, UPS,
    and DHL collectively own hundreds of them because
    they’re cheap. They didn’t spend much purchasing
    these aircraft, so they don’t have to worry about using them enough to offset their cost. UPS does
    have some brand new 747-800 aircraft, which are highly efficient, but they specifically
    schedule these planes on their longest routes so that
    they can recuperate their high purchase price through
    lower fuel costs. With older aircraft, fuel costs might be higher
    since the planes are less efficient, but overall it’s worth it since it allows
    FedEx to profitably leave their planes sitting for all but a
    few hours each day. Some passenger airlines, such as Allegiant
    Airlines in the US, uses the same strategy purchasing cheaper planes to allow
    them to fly fewer hours per day profitably and its
    now a tested and proven business strategy. Express shipping is one of those businesses
    that requires enormous networks to make work which is why you don’t see small shipping
    companies. It’s almost impossible to get started
    in this business unless, of course, you can make your own demand. Amazon, which ships more
    than a million packages per day, is getting into the delivery business. They’ve established a fleet
    of 32 aircraft and are building out their logistics network. When shipping so many packages,
    Amazon is operating at a scale where they can profit by taking the shipping companies
    out of the equation. FedEx, UPS, and DHL, meanwhile, are continuously
    focusing on further increasing the efficiency of their networks since in this
    business more than any, time is money. As you may have noticed, Wendover Productions
    has a new logo and with that I’ve redesigned the website with Squarespace. To be honest, I hadn’t used the website
    builder in a while but this process reminded me of why
    I’m such a fan of Squarespace. It was super simple to
    completely overhaul the site and, in my opinion, it looks great. I didn’t have any issues, but if
    you ever do they have award winning 24/7 customer support that I have used in the past and can
    vouch for. If you run a business, a youtube channel,
    a podcast, or anything else, you want to have a professional web presence like I do with
    my site since that’s how people find you, and you can
    get started building your website with Squarespace for 10% off at squarespace.com/wendover. Squarespace is a great supporter of the show
    so make sure to show them your appreciation by at
    least checking them out at squarespace.com/Wendover. And just one more thing, if you’re like
    me and the first reaction you had to seeing this new logo is wanting a t-shirt of it,
    you’re in luck because they’re now available for pre-order
    at DFTBA. The link is in the description.

    How to Water Ski : Advanced Waterskiing Technique

    November 23, 2019


    I’m Jody Fisher with Jodi’s Ski School and
    Expert Village. I’m about to show you a pass through slalom course. This is more advanced
    slalom water ski pass, 36 miles an hour through the entrance gates and around 6 turn buoys.
    Very rhythmic, quick acceleration, high speeds on crossing on back of the boat at about 70
    miles a hour. Very exhilarating and a great deal of fun.
