  • - [Narrator] These days it's natural to feel a bit lost.

  • Everyone seems to be looking for a sense

  • for where they stand in the world.

  • A reference point on which to ground ourselves.

  • A mental map.

  • When we think of our mental maps

  • of the actual world, however,

  • that is, our intuitive sense for the shape

  • and relative position of places on the planet,

  • it may surprise you to learn that they're a bit off.

  • Many peoples mental maps of Earth, in fact,

  • share the same, fairly significant errors.

  • Relative positions, sizes,

  • and even the existence of minor locations

  • may be totally off-base.

  • The good news is, it's not your fault.

  • One reason for a skewed mental picture of the world

  • is our brains taking shortcuts.

  • Our minds try to simplify the layout

  • of highly detailed things.

  • Such as, the locations of cities

  • and countries around the world.

  • But these shortcuts may not always be accurate.

  • Take, for example, South America.

  • Many may think it's located more

  • or less directly south of North America,

  • with Chile corresponding roughly to California.

  • If you flew straight south from Los Angeles, however,

  • you wouldn't hit land again until Antarctica.

  • In reality, all of continental South America

  • is located east of Florida.

  • In this way, North and South America

  • could also be accurately named

  • west and east America, respectively.

  • These mental misconceptions aren't limited to the Americas.

  • Do you think of Africa as being largely

  • in the Southern Hemisphere?

  • Perhaps it's similar latitudes as South America?

  • In fact, the vast majority of Africa

  • is north of the equator.

  • I bet you never realized

  • that Disney World in Orlando, Florida

  • is closer to the equator

  • than the Great Pyramid of Giza in Egypt.

  • Europe is also much further north than many people realize.

  • A line drawn west out of London, England

  • would never touch the 48 contiguous states.

  • Paris is actually further north than Montreal.

  • Barcelona is around the same latitude as Chicago.

  • Our mental image of Europe being further south

  • than it actually is, may have to do with its weather.

  • Europe has what's called a Mediterranean climate.

  • The result of warm air crossing the Atlantic

  • via the Gulf Stream.

  • This means that many European cities

  • have climates that those of us in the Americas

  • associate with lower latitudes.

  • When we think about the weather in say, Venice,

  • we don't expect it to be located

  • further north than Toronto, but it is.

  • A skewed sense of the world

  • isn't just our brain's fault for taking shortcuts.

  • Every map you've ever seen

  • has been, in some way, distorted from reality.

  • For instance, many of us grew up

  • with maps in school that showed Greenland

  • to be about the same size as South America.

  • In reality, however, South America

  • is more than eight times larger than Greenland.

  • Similarly, most maps make it impossible

  • to see that Brazil is larger

  • than the contiguous United States,

  • and only slightly smaller than Canada.

  • Or that Alaska is actually smaller than Libya.

  • Now, how is it possible that maps can be so misleading?

  • The answer lies in the impossibility of representing

  • a three-dimensional object, the Earth,

  • in only two-dimensions, a map.

  • While a globe can accurately represent

  • relative positions, sizes,

  • and distances on the Earth's surface without issue,

  • compromises must be made

  • when trying to flatten an orb into a map.

  • Cartographers, people who make maps,

  • have developed various methods

  • of depicting the round Earth

  • on a flat surface called projections.

  • Each of these projections represents the earth accurately,

  • in some way, while distorting the planet in others.

  • For instance, one of the most common projections

  • is the Mercator projection.

  • Introduced in 1569 by Gerardus Mercator.

  • Mercator maps are found in classrooms around the world,

  • and it's even the projection used by Google maps.

  • Mercator's goal in developing his projection

  • was to aid in navigation.

  • Any angle on the globe is the same angle on a Mercator map,

  • which assured navigators

  • that they were heading towards their intended destination

  • in the days before GPS.

  • As a result, however, the relative sizes and shapes

  • of continents on Mercator maps are distorted.

  • Especially for land nearer to the poles.

  • As you move further away from the equator,

  • the Mercator projection shows land taking up more area

  • than it actually does on Earth.

  • This is why Antarctica looks so large,

  • while in reality being the third smallest continent.

  • As a result, Mercator projections

  • tend to portray northern countries, such as those in Europe,

  • as being larger than they actually are.

  • Remember how north London actually is?

  • Some scholars maintain that these countries magnification

  • has contributed to imperialist mindset.

  • Essentially allowing small European countries

  • to inflate their position on the world.

  • While the Mercator is one of the most commonly found around

  • and of the world,

  • it is far from the only projection available.

  • Each, like the Mercator,

  • has it's own benefits and drawbacks.

  • None is considered more correct than any other.

  • They're all trying to solve the same impossible problem.

  • Converting something from three-dimensions to two.

  • The only representation of Earth

  • that doesn't make any comprises, a globe.

  • Apart from mental shortcuts and distorted projections,

  • there's another reason why your mental map may be false.

  • You've been intentionally lied to.

  • Before satellites were taking high resolution photos

  • of all the Earth's surfaces 24-hours a day,

  • making a map was a painstaking job.

  • If you spent a ton of time and resources making a map,

  • you needed ways to ensure people wouldn't copy your work

  • and sell it themselves as their own map.

  • One way to do this was

  • by putting intentional errors in maps called trap streets.

  • For instance, if you were mapping your hometown

  • and included a made up street, nothing serious,

  • maybe just a fictional cul-de-sac in the corner of town,

  • and that same fake cul-de-sac

  • appeared in a competitor's map,

  • you could be confident they had stolen your map.

  • According to the grandson of the former president and CEO,

  • Thomas Brothers Maps would put fake streets

  • of people's kids' names, pets' names in little cul-de-sacs,

  • and that was one way we would be able to keep the copyright.

  • One of the most common descriptions of map making

  • is that it is both an art and a science.

  • Historians hypothesize that human consciousness

  • has always had an impulse to try to cognitively map

  • and relate to our physical surroundings,

  • and while human brains

  • may instinctively have an impulse to map,

  • the practice is by no means an innate skill,

  • leading to many distortions

  • in how we mentally believe the world is laid out.

  • It's important to keep in mind how,

  • just like the projections of globes onto maps,

  • the way we view our surroundings

  • is only one of many valid interpretations.

  • Sometimes, when you feel lost in the world,

  • changing perspectives may be just what you need

  • to find your way.

  • (upbeat piano music)
