    The Fake Neighborhoods on Google Maps

    few things you’ve probably never heard of: toast without avocados, three figure rent,
    republicans, and the East Cut neighborhood. If you go on Google Maps though and search
    for East Cut it’ll tell you that’s this neighborhood between Market Street and the
    Bay Bridge even though, before a year ago, nobody had even tried to call this area the
    East Cut. Nowadays, however, the “East Cut” name
    is seeping into the real world all thanks to the world’s benevolent dictator—Google. Now of course Google is amazing and lovely
    and I don’t mean to be critical at all of such a fantastic organization but they do
    have a certain amount of power over, well, everything. More than half of the world’s smartphone
    users have used Google Maps in the past month and, considering that there are 2.5 billion
    smartphone users in the world, that’s a lot. Google Maps is the most popular mapping service
    in the world and that means that when someone wants to figure out what something is, they
    check Google Maps. Quite bafflingly, the benevolent dictator
    almost almost started a war in 2010. You see, where Nicaragua and Costa Rica meet
    on the Atlantic Ocean Nicaragua believes the border to be this while Costa Rica believes
    it to be this. In 2010 a Nicaraguan military troop was sent
    to the area to do dredging work on the San Juan River. While there, though, the troop just happened
    to meander onto Calero Island which, as far as Costa Rica was concerned, was Costa Rica. Now, having a foreign military strut into
    your country with no prior warning doesn’t look great. It looks a whole lot like an invasion so Costa
    Rica, being, interestingly, the most populous country in the world without a military, sent
    70 police officers to make sure that this wasn’t the beginning of the Nicaraguan annexation
    of Costa Rica. In response, Nicaragua sent an additional
    50 troops and the two parties sort of just had a stand off while the two country’s
    leaders had a discussion. As it turned out, the few dozen troops that
    entered Costa Rica had no intentions to singlehandedly overthrow a country of five million. Their commander was just using Google Maps
    to navigate which showed the border as this. Costa Rica then went to the International
    Court of Justice, and complained and then, after years of back and forth, the court ruled
    that this area was in fact Costa Rica and so now Google Maps shows it as Costa Rica
    and Nicaragua lays off the invasions. Unfortunately Apple missed the opportunity
    to create a great Apple Maps ad. Google Maps does try more or less to follow
    what people say places are but sometimes some people disagree on what a thing is. For example, some say New Zealand, other say
    “where?” Some say Machias Seal Island is part of Canada,
    other say it’s part of the US so if you search it on Google it won’t tell you which
    country it is like it does for the rest of the US or Canada. It’ll do the same if you look at a town
    in Western Sahara, Kashmir, the South China Sea, or any other disputed territory. But perhaps the biggest issue for Google Maps
    is what to call neighborhoods. You see, in most cases, neighborhood names
    aren’t official—they’re just decided through what people colloquially call places. People just refer to this area in San Francisco
    as Russian Hill or this area Telegraph Hill, this area Jackson Hill, and at least a few
    people call this area the East Cut. In 2015, you see, an organization was founded
    to improve what was then called Rincon Hill. For some inexplicable reason they decided
    they needed a rebranding and they settled on the neighborhood name “the East Cut.” They updated street signs and their website
    and everything but still, when asked, the mayor of San Francisco said he had never heard
    of the neighborhood. Lucky for the East Cut organization, one of
    their board members just happened to work at Google, whose offices are in the East Cut,
    and, according to the New York Times in an article about this debacle, was able to persuade
    the company to switch the name which is the most San Francisco story ever. Some neighborhood names on Google Maps are
    even more baffling, though. In Detroit Google Maps refers to this area
    as “the Eye” even though really nobody has ever referred to this area by that name. A blogger did some detective work and was
    able to figure out that Google Maps copied the neighborhood names from a map that some
    random website published in 2003. Google Maps even copied the misspellings from
    that map. As it turns out, “the Eye” was the name
    of a community watch organization in the area so there were signs around the area saying
    “the Eye” and somewhere along the line someone got confused and assumed it was the
    neighborhood name. Still today that name shows up on Google Maps
    and, if you really want, you can search and buy real estate in the prestigious Eye neighborhood. In true Detroit fashion, houses start at $8,000. Nobody’s really sure exactly how Google
    determines neighborhood names but, once they do, that name essentially becomes official. According to Google Maps Machias Seal island
    is both Canada and the US at the same time but you know what’s also two things at once—Quantum
    objects since, thanks to Quantum superposition, these particles can be in two or more quantum
    states at the same time. This is what Schrodinger’s Cat is about—it’s
    like if a cat was both dead and alive at the same time. Quantum mechanics is like magic that’s happening
    in our world right now and it’s sort of complicated but Brilliant is the expert in
    teaching super complex things in an understandable way. If you take their quantum objects course you’ll

    How Airlines Price Flights

    August 27, 2019

    a crapshoot. The numbers change seemingly arbitrarily every
    week, day, or hour, but there’s some real science behind these prices. People spend their whole lives figuring out
    what to charge you to fly. Let’s take a look at one flight on one route
    by one airline to understand. American Flight 33 leaves New York’s JFK
    airport every day at 7 AM bound for Los Angeles arriving at 10:51 AM pacific time. This transcontinental route is one of the
    most competitive in the world with over 3.5 million yearly passengers and five major airlines
    connecting the country’s two largest cities. There’s nowhere where pricing strategies
    are more important for airlines than here. Looking at three months of fares for this
    flight, there are eight distinct prices for economy ranging from $129 to $472. These all get you on the exact same flight
    in the exact same seat but each and every price has a purpose and place. The lowest price, $129, is the most competitive
    price. This fare only shows up three times in our
    three month span—each time on Tuesdays. Now, Tuesdays are very often the cheapest
    days of the week to fly. Business travelers tend to make up much of
    the demand during the week and they most often want to fly out on Monday and return on Thursday
    or Friday so Mondays, Thursdays, and Fridays tend to be the most expensive travel days
    while Tuesdays and Wednesdays are often the cheapest. The average ticket price for this flight shows
    this—Tuesdays average $182 and Wednesdays $173. Even if the demand is lower American Airlines
    runs the flight anyways and they have to fill seats to break even so they sell the flight
    at rock-bottom prices. The next price, $144, actually demonstrates
    a very interesting phenomenon. Whenever American prices their flight at $144,
    they are not alone. Take March 6th for example. American, Delta, Virgin America, JetBlue,
    and United all have flights from New York to LA at around 7 in the morning selling for
    $144. They’re doing what is called price matching. Because this is one of the most competitive
    routes in the world and because the number one determinant for travelers on which airline
    they take is price, all five airlines flying this route match each others prices. This way, travelers make their decision based
    off the reputation of each airline rather than the price. The price stays at $144 because it’s in
    each airlines best interest to keep it there. In a normal market, if Delta, for example,
    dropped their price to $119 they would get more travelers since they were the cheapest,
    but in this price matched market all the other airlines would drop their prices as soon as
    Delta drops theirs so all of them would get the same amount of travelers as before while
    earning less money, but there are some cases where it can make business sense for airlines
    to drop prices to below even being profitable. Around the year 2000, WestJet and the now
    defunct CanJet airlines started flying from central Canada to Newfoundland. These routes were historically operated exclusively
    by Air Canada and they were expensive. A one-way flight from Montreal in 1999 cost
    over $600, but when the budget airlines WestJet and CanJet started flying the route, prices
    dropped dramatically and Air Canada was threatened, so they dropped their prices even lower. The $600 Air Canada fares then cost $89. Now, it wouldn’t make sense for anyone to
    fly a budget airline over Air Canada at the same price so WestJet and CanJet were almost
    driven out of business on these routes, until Canada’s Competition Bureau stepped in. They concluded that Air Canada was engaging
    in the uncompetitive action of predatory pricing since they were pricing flights below what
    it cost to operate them, so they were forced to stop. Airlines in the US, with some newly strong
    budget competitors, are engaging in similar actions nowadays. United airlines, for example, is matching
    Frontier’s $40 fares on many days from Denver to Chicago, among other routes, in order to
    maintain their market stronghold in Denver and Chicago even though their cost to operate
    the route is drastically higher than Frontier so they are almost certainly loosing money
    on those fares. But back to the New York to LA route. $159 is the lowest regular fare for this flight. The $129 and $144 price points were both basic
    economy fares—the most restrictive type with no seat selection, no carry on bags,
    and no changes or refunds. Every flight has a bunch of different booking
    classes each with a fare code. For example, the basic economy fare code for
    the $129 and $144 price is B, but the $159 price books into fare code N. These different
    booking classes are sometimes known are fare buckets. Essentially the airline decides it’s going
    to sell a certain number of tickets at the $159 price with fare code N, let’s say 10,
    then when those ten tickets are sold the airline then sells economy at fare code G for $204
    then when those are sold it sells economy at fare code V for $269 then fare code L for
    $318 and so on and so forth. There are also some cases where a ticket will
    default to a more expensive fare bucket because of reasons other than the lower fare selling
    out. Many fares, including each mentioned so far,
    have advance purchase requirements meaning that, even if a flight is not full at all,
    the price will increase closer to departure. All the fares below $204 have an advance purchase
    requirement of two weeks meaning that you can only purchase them more than two weeks
    before departure while the $269 fare, for example, has an advance purchase requirement
    of only one week. Although, the cheapest fare without an advance
    purchase requirement at all, that is, the cheapest fare that you could buy day-of for
    this flight is fare class K at $472 which happens to be the most expensive economy class
    fare. And now for some caveats. Not every fare for this flight is going to
    be priced at one of these eight prices. Airlines have mechanisms to adjust fares from
    these buckets. In the short-term, they can adjust things
    like the fuel surcharge to raise the price if other factors, like oil prices, increase. In the long term they can adjust the actual
    prices of the different fare buckets. Airline often increase the base fares for
    busy seasons like summer. American Airlines does exactly that on this
    New York to LA route where their fare class M, for example, increases from $357 to $410
    in August. But so far we’ve looked at this at a micro
    level—how prices differ on one flight—but we also have to consider the macro level. Why if you leave on Tuesday February 6th and
    fly 2,469 miles to the west to LA do you pay $129 while if you fly 3,442 miles to the east
    to London—only a thousand miles further than LA—you pay $2,772. Well, the second figure is a bit deceptive
    because that’s the price of a one-way ticket. If you switch the LA flight to a round-trip
    ticket returning a week later it will cost $257—exactly double—while if you turn
    the London flight into a round-trip returning a week later the price will drop to $602—almost
    five times less. This is understandably confusing—a one-way
    ticket that costs more than a roundtrip—but the reason this is goes back to the fare codes. Embedded within each fare code are a bunch
    of little restrictions that dictate when you can use that fare. On the New York to LA trip those restrictions
    are just things like blackout dates for the fare and advance purchase requirements, but
    the New York to London ticket has loads more restrictions and the ones that make one-ways
    more expensive than round-trips are the minimum stay requirements. These requirements dictate how soon your return
    flight can be in order to get a particular fare. The idea is to price discriminate—business
    travelers should pay more because they can pay more. Meanwhile, airlines try to give the lowest
    prices to leisure travelers since they’re the ones paying for their own tickets and
    therefore they’re the ones that are the most price sensitive. Business travelers often want to be home for
    the weekend, so many of these minimum stay requirements, like with fares Q, N, and S,
    just require a Sunday at your destination. Others, trying to accomplish the same thing,
    require seven days, a full week, which would also require a traveller to stay the weekend
    at their destination. Now as the prices go up the requirements go
    down so once you get to paying around $2000 you can stay for as few as three days, but
    the cheapest roundtrip base airfare with no stay requirement at all is $5,544 in fare
    class Y—exactly double the one way price. So that explains this—the one way ticket
    is so expensive because, since the airline doesn’t know how long the traveller will
    stay at their destination the one-way fare has to be booked into the least restrictive
    fare class without the minimum stay requirement. You’ll see this idea of price discrimination
    all over ticketing structures. It’s a genius pricing concept that allows
    different people to buy products at the prices they can afford and therefore its allows businesses
    to sell the same product to more people. Tickets increase in price closer to departure
    because leisure travelers buy tickets far-out and business travelers buy their tickets close
    to departure and flexible tickets are more expensive because that’s what business travelers
    need, but there’s another pricing difference going on that’s less fair—between routes. It’s all about competition. Different routes of the same distance cost
    different amounts generally not because they cost different amounts to operate, but because
    of how much the competitors are charging. This is part of why flights into small airports
    are so expensive—because they lack competition. You can fly the 240 miles from Detroit to
    Pellston, Michigan on a CRJ 200 for $242 or you can fly the 170 miles from Detroit to
    South Bend, Indiana on a CRJ 200 for $76. The only difference is that South Bend Airport
    has flights from United, Delta, and Allegiant while Pellston only has flights from Delta. The same phenomenon happens over the Atlantic. There’s more competition on the six hour
    flight from New York to LA than on the six hour flight from New York to Dublin so you
    can fly to LA for $250 round trip while Dublin costs $500 round trip. Of course, travelers from New York to LA can
    drive, take the bus, take the train, or take a flight connecting halfway there while travelers
    to Dublin only have one choice—to fly. In all, the truth is that prices reflect what
    people will pay and so people will pay what flights are priced. If you’re a busy person like me, you know
    that eating healthy can be difficult. Sometimes it seems like you have two choices—quick
    food or healthy food—but you have another one—quick and healthy food because that’s
    what Blue Apron is. Blue Apron ships you boxes every week with
    farm-fresh pre-apportioned ingredients and recipes that let you make these delicious,
    healthy meals in at the very most 40 minutes. I recently made the Spicy Pork and Korean
    Rice Cakes meal which was delicious and quick. With Blue Apron, you’re sure to get stuff
    that you’ll actually like because they have a selection of eight different recipes each
    week from which you can pick. All the ingredients arrive in a refrigerated
    bag, ship to most everywhere in the US, and start at just $8.99/10.99 per serving. I highly recommend you try Blue Apron out
    and the good news is that you can try out three meals for free at the link in the description.

    Why Iceland Imports Ice

    August 22, 2019


    This video was made possible by Squarespace. Build your beautiful website with Squarespace
    for 10% off at squarespace.com/HAI. Chances are that somewhere on the internet
    you’ve heard the “fact” that Iceland was named Iceland by its viking settlers to
    stop their enemies from coming to the island. Well, that fact is about as wrong as pineapple
    on pizza. The truth is that the first norse settler
    of the island was feeling a little bummed out upon arrival since his daughter and livestock
    died en route so he just stayed for the winter before returning to Norway and, since the
    particular area he stayed in happened to be icy he figured all of the island was icy and
    therefore called it Iceland. Of course that’d be as absurd as, you know,
    seeing that the sidewalk was flat and deciding the whole earth must be flat, or something. Iceland is cold and has plenty of snow and
    ice during the winter but as a whole, the country is fairly green. Still, for such a northern and wintery country
    the idea that it imports ice is pretty absurd. Nonetheless that is reality but Iceland’s
    ice importation has a surprisingly rational explanation. Now, taking ice from one place and selling
    it in another is nothing new. El Chapo was great at it but as it turns out,
    centuries ago people’s refrigerators didn’t have ice dispensers. For the majority of history people just dealt
    with having warm drinks like cave-people but when the 19th century rolled around that all
    changed. An entrepreneur named Frederic Tudor started
    taking ice from cold places like Maine and selling it in hot places like Cuba. Genius, right? Only problem, ice melts. Frederic understood this and insulated his
    cargo with sawdust and, with enough ice, at least some of it would make it through the
    1,600 mile journey from Maine to Cuba. At first Frederick received a frosty reception
    from the hot place people as they were doubtful that they needed ice so Frederic channeled
    his inner drug dealer and gave them their first bit of ice for free to get them addicted. Soon, business was booming. Now, places like New York and DC get too cold
    in the winter for people to want ice but in the summer, they too get swelteringly hot
    so Frederic wanted to make a way to be able to sell ice in the mid-Atlantic summers. Really the only solution was to take a whole
    lot of ice, put it in an insulated building, and hope some of it lasts until summer and,
    crazily enough, that worked. Most of North America started to rely on ice
    so it was time for Frederick to take the ice trade intercontinental. The rest of the world also had hot places
    like India so Frederic Tudor set up a regular shipment of ice to Calcutta, India which became
    hugely popular with the rich English colonialists who were used to cooler temperatures. Amazingly, he had the process refined so well
    at that point that the ice from New England was selling in India for, adjusted for inflation,
    only $1 per pound. Soon after, ice from New England was shipped
    and sold in London, in Rio de Janeiro, in Cape Town, in Hong Kong, the New England ice
    even reached as far as Sydney, Australia where it sold for only $2 per pound. So, was it a coincidence that the climate
    starting rapidly warming only a century after the world’s elite started using ice shipped
    from the other side of the world by steamship all so they could have a chilled beverage? I’m not saying the ice trade singlehandedly
    caused climate change, but it certainly didn’t help. Of course, with time artificial refrigeration
    became cheap and widespread but not before making Frederic Tudor a very rich man. Iceland today, despite what some may think,
    is not some backwards heathen society that shuns the use of refrigerators. Its importation of ice has to do with something
    else—economics. You see, Iceland is a very expensive place. Like many isolated, northern counties, Iceland
    relies on imports for many things like oil, wood, wheat, and other food. It just doesn’t have the ability to produce
    these items domestically due to its geography but shipping to Iceland is also relatively
    cheap since its economy is export-driven. While fish is Iceland’s biggest export this
    is mostly shipped by plane but the country also has an enormous aluminum industry thanks
    to its low electricity cost. Aluminum, along with most everything else
    Iceland makes, is exported by ship which means that there’s demand for shipping from Iceland. That means that ships are already coming to
    Iceland to bring items elsewhere so its relatively inexpensive to fill those ships with other
    goods to bring to Iceland. At the same time, the average Icelander makes
    about $57,000 per year, it’s one of the highest income countries in the world, so
    that means making things in Iceland, in most cases, is expensive. If you go and check your handy dandy Icelandic
    schedule of tariffs, though, you see that water, ice, and snow have no import duty if
    imported from the European Economic Area. Therefore, Iceland imports ice from other
    less expensive countries in the EEZ such as Scotland and the only additional cost is the
    cheap shipping. While there are plenty of other countries
    that don’t charge import duties on ice, there are few that have the mix of high domestic
    labor costs and cheap inbound shipping that make it worth it for Iceland to import ice. That’s why Iceland’s grocery stores are
    stocked with this imported ice from hundreds or thousands of miles away as it ends up being
    about 40% less than Icelandic ice. If you want to sell a different kind of ice

    Brazil’s Geography Problem

    Brazil’s Geography Problem

    August 14, 2019


    This video was made possible by Skillshare. Learn from 21,000 classes for free for two
    months at https://skl.sh/wendover3. There are plenty of lines you can draw on
    the globe but perhaps none is more consequential than the equator. Of the 15 wealthiest countries
    in the world as measured by GDP per capita, all are in the northern hemisphere. Only 800
    million of earth’s 7.6 billion residents live south of the equator. There is a clear
    divide between north and south but of those 800 million people a quarter of them, about
    207 million, live here in Brazil. The country is an exception to the global trend. Brazil
    is the fifth most populous country in the world and the most populous entirely within
    the southern hemisphere. Its economy has grown enormously and the country is quickly developing.
    Although, the very land it sits on stacks the odds against it. Its location gives it
    a disadvantage. Given this, the question is whether Brazil can develop into a world superpower
    by the likes of the US, Europe, Russia, India, and China or if the country is doomed to fail? Brazil, of course, looks like this but in
    reality almost 80% of the country’s population lives here—within 200 miles of the coast.
    You do see a concentration of population near the coast in any country as it provides a
    cheap and easy means of transportation by boats and a source of food through fishing
    but few countries have such a severe concentration of people by the oceans as Brazil. This small
    area, for example, is home to three of Brazil’s six largest cities. Normally this would help
    development as the area in between cities will urbanize but this map doesn’t tell
    the whole story—this one does. You see, this area of Brazil is rather mountainous.
    The major cities mostly exist in small pockets of low-altitude, flat land on the ocean. This
    is because major cities need easy water access to get goods in and out. The majority of Brazil’s
    coast is defined by steep, sheer cliffs. Petrópolis, for example, a suburb of Rio, is a mere 13
    miles from the ocean and yet it sits at almost 3,000 feet of altitude. The rare areas with
    low-altitude land on the water are where cities like Porte Alegre, Rio de Janeiro, and Recife
    are but this pattern has two consequences. First, these cities, while being on flat land
    themselves are surrounded by cliffs and mountainous regions which means their growth is limited.
    There are plenty of cities that exist in mountainous regions but the world’s largest and most
    influential cities like London and Delhi and Beijing all exist in areas with absolutely
    no geographical features limiting their growth. The fact that Brazil’s cities locate in
    rare low-altitude coastal land means that the country will likely never have a megalopolis
    by the likes of the Pearl River Delta or the US Northeast. It takes a surprising six hours
    to drive between Rio and Sao Paolo and since there’s no low-altitude coastal land in
    between them, there are really no major cities in between them too. Brazil’s cities are
    confined to the geographically convenient areas which are spread out from each other.
    This means the cities can’t collaborate easily with each other thereby limiting Brazil’s
    impact on the world stage. Like any large country, Brazil’s development
    potential is also linked to how it gets its food. This, in fact, might be Brazil’s greatest
    obstacle as it really doesn’t hav e much great farmland, at least yet. The country’s
    main agricultural region is its south which is blessed with great soil and great rivers
    that help transport crops away from their farms. Interestingly, the same elevation that
    leads to steep coastal cliffs causes rivers to run in a counterintuitive direction. The
    Tietê river, for example, starts near Sao Paolo a mere 10 miles away from the Atlantic
    ocean but then runs inland almost 500 miles where it flows into the Paraná River which
    eventually flows out into the ocean near Buenos Aires, Argentina. If a farmer wants to export
    their food abroad, it’s often cheaper to first ship it the thousands of miles by boat
    on these rivers than just hundreds of miles overland to Brazil’s coast due to their
    poor road infrastructure. This means that Argentina gets the business of packing up
    and shipping Brazil’s food to other countries. That’s just lost money for Brazil as a result
    of their geography. Brazil’s south, though, does not even have enough land to feed the
    country’s own 200 million residents. Given that, the question is where to put the rest
    of the farms. In Brazil’s north is the Amazon basin. The
    central feature of this region is, of course, the Amazon River which is navigable for boats.
    Normally this feature would lead to a significant population as navigable rivers serve as cheap
    and easy transport for crops and goods but the banks of the Amazon are a tough place
    to farm or live. Not only are they muddy and unstable which makes building difficult, but
    the Amazon also regularly floods which means that every year many of the communities on
    the banks of the Amazon can have their streets underwater for months. Building and living
    in the Amazonian cities is difficult, but what’s more difficult is building the roads
    in and out. The largest city in the Amazon, Manaus, is home to 2.6 million people, it’s
    as big as Baltimore, and yet there are only three roads connecting the city to the outside
    world. Many of the smaller towns around the Amazon have no roads going in and out as its
    just incredibly costly and difficult to build roads through the rainforest. In fact, rather
    unbelievably, there is not a single bridge spanning over the Amazon so there is no way
    to drive from the northernmost region of Brazil to the rest without taking a ferry. Overall,
    this whole area is just empty. Even if there was the infrastructure to transport crops
    to market, farming in the Amazon involves clearing huge amounts of land and even then,
    the soil is relatively infertile which leads to poor yields. Despite being Brazil’s largest
    state, Amazonas is home to just 1.8% of its population. It just costs too much to build
    the infrastructure needed to live there. To the south of the Amazon, though, is an
    area known as the Cerrado. This vast savanna used to be in the same category as the Amazon—it
    was empty. The problem was not only that there was no natural network of rivers to get crops
    out of the area but also that the soil was too acidic and lacking enough nutrients to
    easily grow large quantities of crops. Between both the Amazon and the Cerrado being off-limits
    for large-scale farming, that meant that Brazil really didn’t have much land at all for
    farming. 30 years ago, with only the south to farm, Brazil was actually a net importer
    of food—it bought more food from other countries than it sold. That was until researchers discovered
    that all you needed to do to fix the soil was add phosphorous and lime. The phosphorous
    served as a fertilizer in the place of natural nutrients and the lime worked to reduce the
    level of acidity. In the early 2000’s, the country spread more than 25 million tons of
    lime per year and so today the Cerrado accounts for 70% of Brazil’s farmland. In addition,
    Brazil has begun growing soybeans. This plant is normally grown in more temperate climates
    such as the US, northern China, or Japan, but through cross-breeding and genetic modification
    it can be modified to grow in warmer and acidic environments such as the Brazilian Cerrado.
    Thanks to the enormous amount of land Brazil has and these technological advancements the
    country has gone from producing 16% of the world’s soybean in 2005 to 31% today.
    A country’s level of development is often to linked to how good its natural transportation
    system is. That’s part of why the US developed so much so fast—it has a great system of
    navigable rivers right in its agricultural heartland that helps get goods from the fields
    to cities fast and inexpensively. The Brazilian Cerrado, though, does not have that. It doesn’t
    even have much of a preexisting network of roads since before this recent agricultural
    advancement barely anyone lived there. Therefore anyone who wants to farm in the Cerrado has
    to find land, level it, treat it with phosphate and lime, and build roads to get supplies
    in and crops out. Cerrado farms can be profitable but it takes an enormous amount of money to
    build the infrastructure needed to start a farm. It’s not like the US or France or
    China where all you need is some land. The consequence of this is that farms in Brazil
    tend to owned by corporations rather than individuals because only corporations have
    the money to build farms. That therefore increases the level of wealth disparity in Brazil. According
    to the World Bank’s Gini index, Brazil is the 11th most economically unequal country
    in the world. Lower wealth disparity and the emergence of a middle class are indicators
    of economic development so the country should want to fix this. Brazil’s government has
    recognized its infrastructure problem as a source of its wealth disparity and has therefore
    worked to build roads in the interior so that more individuals can run farms but the government
    only has so much money to spend and it’s a big country.
    Brazil does, though, understand the importance of its core. It understands that the coastal
    cities are constrained and that economic development will come from the center. It was partially
    for that reason that the country decided to move its capital from Rio de Janeiro to here—Brasília.
    The thinking was that putting the capital in the core would stimulate the economically
    underdeveloped region and, in many ways, it worked. The city simply did not exist before
    1960 yet today more than 4 million people live in its metropolitan area. Being located
    on relatively flat land unlike Rio, the city can just grow and grow and grow without hinderance.
    Brazil has potential, but its defining issue is that it’s an expensive place. It’s a
    vicious cycle. In order to make money, Brazil needs to invest in its infrastructure but
    without people making money it doesn’t have the tax money to build what it takes t o transition
    into the first world. The question of why tropical countries are less developed is an
    enormous one without a clear answer, but Brazil is one of the most likely candidates to break
    this trend. It certainly lags behind other developing countries like China, but as its
    agriculture industry develops it will become a bigger and bigger exporter which will bring
    more money in. With time, its average income will inch up. The country already does have
    major companies in other industries such as banking, manufacturing, and oil but with how
    big Brazil is, agriculture is the one that’s the world’s focus right now. Only France,
    Germany, the Netherlands, and the United States export more agricultural products per year
    which is good company to be in. Brazil may not have the explosive growth rate of some
    other less developed countries but by continuously taking what it earns and reinvesting it to
    open up more of the country to agricultural production it will continue its path to superpower
    status. One of the common questions I receive is how
    I started making these videos. The first step was learning the skills needed from writing
    to research to sound design and editing, but for each and every one of them there’s a
    course on Skillshare. Skillshare, you see, is an online learning community that has more
    than 21,000 classes on whatever you want to learn. The variety is astounding. You can
    learn skills to help you make videos, to show off at parties, or even to help you get a
    job. There are also some great courses taught by fellow YouTubers such as Mike Boyd and
    Kurzgesagt. What’s best about Skillshare is that you can try it all for free for two

    Why the World’s Smallest Country Has a Railroad

    August 8, 2019


    This video was made possible by Brilliant. Start learning intuitively with Brilliant

    smallest country has a railroad. Well, the Vatican has a railroad because the
    Roman Empire was awesome. There’s the answer. Now I know what you’re thinking—“you
    just gave me the answer why should I stick around for the rest of the video?” The Vatican, like Canada, is a pretty cool
    place. It has the world’s highest density of Popes,
    the world’s highest wine consumption per capita, and compared to me it’s pretty huge. Compared to other countries, though, it’s
    on the smaller side. It’s about 3,000 feet wide and 2,500 feet
    tall. If you took the tallest building in the world,
    the Burj Khalifa, and laid it on its side over the Vatican you would be responsible
    for the death of thousands. Despite its small size, the Vatican is a fully
    recognized and sovereign country with its own government, its own banks, own stamps,
    own passports, postal system, radio station, police officers, fire fighters, and, of course,
    railroad. Being smack dab in the middle of Rome, it’s
    not exactly hard to get to the Vatican. There are no border controls between it and
    Italy so anyone can pretty much stroll into the country without even realizing and there
    are also, of course, roads going in and out. Now, considering the runway of the nearby
    Rome Fiumicino Airport is more than twice as long as the Vatican is wide, there is no
    airport in the country. This isn’t all that unique. Four other countries don’t have airports—Andorra,
    Liechtenstein, Monaco, and San Marino. Now, it would’t be unreasonable to think
    that the Vatican, the smallest country in the world, also doesn’t have a railroad
    because plenty of countries don’t have railroads. Libya, the 16th largest country in the world,
    does not have a foot of functional railroad track but there are a lot of things Libya
    doesn’t have… like a functional government. Even some of the world’s most highly developed
    nations like Qatar and Iceland lack trains. I don’t know if it’s related but both
    countries have some interesting beliefs—Iceland believes in Elves and Qatar believes in wealth
    disparity. The Vatican though, has a railroad and quite
    fittingly, it’s the smallest national railroad in the world. But why? Now for the worst part of the video—the
    bit you actually learn stuff. So, back during the Roman Empire Italy looked
    like this—it was all together. But then the Roman Empire stopped existing
    which was a bummer unless you were Theoderic the Great who ruled a united Italy under the
    Ostrogothic Kingdom until that fell and they eventually became part of the Frankish empire,
    which frankly sucked, and so Italy fell apart faster than a Kickstarter funded startup into
    a bunch of city-states as it remained for the next 1000 years until people remembered
    how awesome the Roman Empire was and decided that Italy should be united once again. Everyone thought that was a great idea except
    the Pope who controlled this land—the Papal States. The new Kingdom of Italy disagreed with the
    Vatican’s obviously irrational desire to keep hold of the only territory they had so
    they took it and so the Pope wasn’t happy. For the next 60 years the different popes
    did not leave the presently unrecognized country of the Vatican at all as a way to protest
    Italy’s claim to Rome which is exactly the level of stubbornness I admire. That was until 1929 when the two parties signed
    the Lateran Treaty which said, “hey, we’re chill,” in exchange for money, a recognized
    sovereign state, and a free railroad. The Vatican rail line originates in Rome at
    a nearby rail station, curves off over a viaduct, then enters the state through a 35 ton iron
    gate that’s closed when there’s no traffic to keep Italy from invading by train which
    I guess was a concern? Immediately on the other side of the wall
    is the Vatican City train station. While this whole branch is run by the country,
    only about 200 feet of track are actually within the Vatican which definitively makes
    this the smallest national railroad in the world. You could walk from one end of the line to
    the other faster than you could walk to the moon. This railroad has been occasionally used by
    Popes to get to the Papal summer palace south-east of Rome, but nowadays its main purpose is
    to get food and supplies in and out of the country without having to drive trucks through
    the crowded streets of Rome. With the exception of a once-weekly train
    for tourists, there are no scheduled passenger trains to the station. If you become the next Pope and decide to
    extend the rail line to two or maybe even three stations there are a lot of things you’re
    going to need to learn like which bank angle to use so that trains can go around curves
    without derailing, how much to adjust timetables to account for slower running during repair
    work, and how to open the Vatican’s secret underworld housing the real Slim Shady. Luckily, you can learn two of those three
    things in brilliant.org’s classical mechanics course. This course, like all Brilliant courses, makes
    learning complex topics simple by first breaking concepts down into their intuitive principles
    then combining those to build up to the answer. It’s seriously the best way to learn. If classical mechanics isn’t your thing,
    they have loads of other courses on topics like probability, astronomy, machine learning,
    and my favorite, logic. Best of all, you can try Brilliant for free
