This is a map of New York State
that was made in 1937 by the General Drafting Company.
It's an extremely famous map among cartography nerds,
because down here at the bottom of the Catskill Mountains,
there is a little town called Roscoe --
actually, this will go easier if I just put it up here --
There's Roscoe, and then right above Roscoe is Rockland, New York,
and then right above that is the tiny town of Agloe, New York.
Agloe, New York, is very famous to cartographers,
because it's a paper town.
It's also known as a copyright trap.
Mapmakers -- because my map of New York and your map of New York
are going to look very similar, on account of the shape of New York --
often, mapmakers will insert fake places onto their maps,
in order to protect their copyright.
Because then, if my fake place shows up on your map,
I can be well and truly sure that you have robbed me.
Agloe is a scrabblization of the initials of the two guys who made this map,
Ernest Alpers and Otto [G.] Lindberg,
and they released this map in 1937.
Decades later, Rand McNally releases a map
with Agloe, New York, on it, at the same exact intersection
of two dirt roads in the middle of nowhere.
Well, you can imagine the delight over at General Drafting.
They immediately call Rand McNally, and they say,
"We've caught you! We made Agloe, New York, up.
It is a fake place. It's a paper town.
We're going to sue your pants off!"
And Rand McNally says, "No, no, no, no, Agloe is real."
Because people kept going to that intersection of two dirt roads --
(Laughter)
in the middle of nowhere, expecting there to be a place called Agloe --
someone built a place called Agloe, New York.
(Laughter)
It had a gas station, a general store, two houses at its peak.
(Laughter)
And this is of course a completely irresistible metaphor to a novelist,
because we would all like to believe that the stuff that we write down on paper
can change the actual world in which we're actually living,
which is why my third book is called "Paper Towns".
But what interests me ultimately more than the medium in which this happened,
is the phenomenon itself.
It's easy enough to say that the world shapes our maps of the world, right?
Like the overall shape of the world is obviously going to affect our maps.
But what I find a lot more interesting is the way
that the manner in which we map the world changes the world.
Because the world would truly be a different place if North were down.
And the world would be a truly different place
if Alaska and Russia weren't on opposite sides of the map.
And the world would be a different place
if we projected Europe to show it in its actual size.
The world is changed by our maps of the world.
The way that we choose -- sort of, our personal cartographic enterprise,
also shapes the map of our lives,
and that in turn shapes our lives.
I believe that what we map changes the life we lead.
And I don't mean that in some, like, secret-y Oprah's Angels network, like,
you-can-think-your-way- out-of-cancer sense.
But I do believe that while maps don't show you where you will go in your life,
they show you where you might go.
You very rarely go to a place that isn't on your personal map.
So I was a really terrible student when I was a kid.
My GPA was consistently in the low 2s.
And I think the reason that I was such a terrible student
is that I felt like education was just a series of hurdles
that had been erected before me,
and I had to jump over in order to achieve adulthood.
And I didn't really want to jump over these hurdles,
because they seemed completely arbitrary, so I often wouldn't,
and then people would threaten me, you know,
they'd threaten me with this "going on [my] permanent record,"
or "You'll never get a good job."
I didn't want a good job!
As far as I could tell at eleven or twelve years old,
like, people with good jobs woke up very early in the morning,
(Laughter)
and the men who had good jobs, one of the first things they did
was tie a strangulation item of clothing around their necks.
They literally put nooses on themselves,
and then they went off to their jobs, whatever they were.
That's not a recipe for a happy life.
These people -- in my, symbol-obsessed, twelve year-old imagination --
these people who are strangling themselves
as one of the first things they do each morning,
they can't possibly be happy.
Why would I want to jump over all of these hurdles
and have that be the end?
That's a terrible end!
And then, when I was in tenth grade, I went to this school,
Indian Springs School, a small boarding school,
outside of Birmingham, Alabama.
And all at once I became a learner.
And I became a learner, because I found myself
in a community of learners.
I found myself surrounded by people
who celebrated intellectualism and engagement,
and who thought that my ironic oh-so-cool disengagement
wasn't clever, or funny,
but, like, it was a simple and unspectacular response
to very complicated and compelling problems.
And so I started to learn, because learning was cool.
I learned that some infinite sets are bigger than other infinite sets,
and I learned that iambic pentameter is and why it sounds so good to human ears.
I learned that the Civil War was a nationalizing conflict,
I learned some physics,
I learned that correlation shouldn't be confused with causation --
all of these things, by the way,
enriched my life on a literally daily basis.
And it's true that I don't use most of them for my "job,"
but that's not what it's about for me.
It's about cartography.
What is the process of cartography?
It's, you know, sailing upon some land, and thinking,
"I think I'll draw that bit of land,"
and then wondering, "Maybe there's some more land to draw."
And that's when learning really began for me.
It's true that I had teachers that didn't give up on me,
and I was very fortunate to have those teachers,
because I often gave them cause to think there was no reason to invest in me.
But a lot of the learning that I did in high school
wasn't about what happened inside the classroom,
it was about what happened outside of the classroom.
For instance, I can tell you
that "There's a certain Slant of light, Winter Afternoons --
That oppresses, like the Heft Of Cathedral Tunes --"
not because I memorized Emily Dickinson in school
when I was in high school,
but because there was a girl when I was in high school,
and her name was Amanda, and I had a crush on her,
and she liked Emily Dickinson poetry.
The reason I can tell you what opportunity cost is,
is because one day when I was playing Super Mario Kart on my couch,
my friend Emmet walked in, and he said,
"How long have you been playing Super Mario Kart?"
And I said, "I don't know, like, six hours?" and he said,
"Do you realize that if you'd worked at Baskin-Robbins those six hours,
you could have made 30 dollars, so in some ways,
you just paid thirty dollars to play Super Mario Kart."
And I was, like, "I'll take that deal."
(Laughter)
But I learned what opportunity cost is.
And along the way, the map of my life got better.
It got bigger; it contained more places.
There were more things that might happen,
more futures I might have.
It wasn't a formal, organized learning process,
and I'm happy to admit that.
It was spotty, it was inconsistent, there was a lot I didn't know.
I might know, you know, Cantor's idea
that some infinite sets are larger than other infinite sets,
but I didn't really understand the calculus behind that idea.
I might know the idea of opportunity cost,
but I didn't know the law of diminishing returns.
But the great thing about imagining learning as cartography,
instead of imagining it as arbitrary hurdles
that you have to jump over,
is that you see a bit of coastline, and that makes you want to see more.
And so now I do know at least some of the calculus
that underlies all of that stuff.
So, I had one learning community
in high school, then I went to another for college,
and then I went to another,
when I started working at a magazine called "Booklist,"
where I was an assistant, surrounded by astonishingly well-read people.
And then I wrote a book.
And like all authors dream of doing,
I promptly quit my job.
(Laughter)
And for the first time since high school,
I found myself without a learning community, and it was miserable.
I hated it.
I read many, many books during this two-year period.
I read books about Stalin,
and books about how the Uzbek people came to identify as Muslims,
and I read books about how to make atomic bombs,
but it just felt like I was creating my own hurdles,
and then jumping over them myself, instead of feeling the excitement
of being part of a community of learners, a community of people
who are engaged together in the cartographic enterprise
of trying to better understand and map the world around us.
And then, in 2006, I met that guy.
His name is Ze Frank.
I didn't actually meet him, just on the Internet.
Ze Frank was running, at the time, a show called "The Show with Ze Frank,"
and I discovered the show,
and that was my way back into being a community learner again.
Here's Ze talking about Las Vegas:
(Video) Ze Frank: Las Vegas was built in the middle of a huge, hot desert.
Almost everything here was brought from somewhere else --
the sort of rocks, the trees, the waterfalls.
These fish are almost as out of place as my pig that flew.
Contrasted to the scorching desert that surrounds this place,
so are these people.
Things from all over the world have been rebuilt here, away from their histories,
and away from the people that experience them differently.
Sometimes improvements were made -- even the Sphinx got a nose job.
Here, there's no reason to feel like you're missing anything.
This New York means the same to me as it does to everyone else.
Everything is out of context, and that means context allows for everything:
Self Parking, Events Center, Shark Reef.
This fabrication of place could be one of the world's greatest achievements,
because no one belongs here; everyone does.
As I walked around this morning, I noticed most of the buildings
were huge mirrors reflecting the sun back into the desert.
But unlike most mirrors,
which present you with an outside view of yourself embedded in a place,
these mirrors come back empty.
John Green: Makes me nostalgic for the days
when you could see the pixels in online video.
(Laughter)
Ze isn't just a great public intellectual, he's also a brilliant community builder,
and the community of people that built up around these videos
was in many ways a community of learners.
So we played Ze Frank at chess collaboratively, and we beat him.
We organized ourselves to take a young man on a road trip across the United States.
We turned the Earth into a sandwich,
by having one person hold a piece of bread at one point on the Earth,
and on the exact opposite point of the Earth,
have another person holding a piece of bread.
I realize that these are silly ideas, but they are also "learny" ideas,
and that was what was so exciting to me,
and if you go online, you can find communities like this all over the place.
Follow the calculus tag on Tumblr,
and yes, you will see people complaining about calculus,
but you'll also see people re-blogging those complaints,
making the argument that calculus is interesting and beautiful,
and here's a way in to thinking about the problem that you find unsolvable.
You can go to places like Reddit, and find sub-Reddits,
like "Ask a Historian" or "Ask Science,"
where you can ask people who are in these fields
a wide range of questions,
from very serious ones to very silly ones.
But to me, the most interesting communities of learners
that are growing up on the Internet right now are on YouTube,
and admittedly, I am biased.
But I think in a lot of ways, the YouTube page resembles a classroom.
Look for instance at "Minute Physics,"
a guy who's teaching the world about physics:
(Video) Let's cut to the chase.
As of July 4, 2012, the Higgs boson is the last fundamental piece
of the standard model of particle physics to be discovered experimentally.
But, you might ask, why was the Higgs boson
included in the standard model,
alongside well-known particles like electrons and photons and quarks,
if it hadn't been discovered back then in the 1970s?
Good question. There are two main reasons.
First, just like the electron is an excitation in the electron field,
the Higgs boson is simply a particle which is an excitation
of the everywhere-permeating Higgs field.
The Higgs field in turn plays an integral role
in our model for the weak nuclear force.
In particular, the Higgs field helps explain why it's so weak.
We'll talk more about this in a later video,
but even though weak nuclear theory was confirmed in the 1980s, in the equations,
the Higgs field is so inextricably jumbled with the weak force, that until now
we've been unable to confirm its actual and independent existence.
JG: Or here's a video that I made
as part of my show "Crash Course," talking about World War I:
(Video) The immediate cause was of course the assassination in Sarajevo
of the Austrian Archduke Franz Ferdinand,
on June 28, 1914, by a Bosnian-Serb nationalist named Gavrilo Princip.
Quick aside: It's worth noting
that the first big war of the twentieth century began
with an act of terrorism.
So Franz Ferdinand wasn't particularly well-liked
by his uncle, the emperor Franz Joseph -- now that is a mustache!
But even so, the assassination led Austria to issue an ultimatum to Serbia,
whereupon Serbia accepted some, but not all, of Austria's demands,
leading Austria to declare war against Serbia.
And then Russia, due to its alliance with the Serbs, mobilized its army.
Germany, because it had an alliance with Austria,
told Russia to stop mobilizing,
which Russia failed to do, so then Germany mobilized its own army,
declared war on Russia, cemented an alliance with the Ottomans,
and then declared war on France, because, you know, France.
(Laughter)
And it's not just physics and world history
that people are choosing to learn through YouTube.
Here's a video about abstract mathematics.
(Video) So you're me, and you're in math class yet again,
because they make you go every single day.
And you're learning about, I don't know, the sums of infinite series.
That's a high school topic, right?
Which is odd, because it's a cool topic, but they somehow manage to ruin it anyway.
So I guess that's why they allow infinite series in the curriculum.
So, in a quite understandable need for distraction, you're doodling
and thinking more about what the plural of "series" should be
than about the topic at hand: "serieses," "seriese," "seriesen," and "serii?"
Or is it that the singular should be changed: one "serie," or "serum,"
just like the singular of "sheep" should be "shoop."
But the whole concept of things
like 1/2 + 1/4 + 1/8 + 1/16 and so on approaches one, is useful if, say,
you want to draw a line of elephants,
each holding the tail of the next one:
normal elephant, young elephant, baby elephant, dog-sized elephant,
puppy-sized elephant, all the way down to Mr. Tusks and beyond.
Which is at least a tiny bit awesome,
because you can get an infinite number of elephants in a line,
and still have it fit across a single notebook page.
JG: And lastly, here's Destin, from "Smarter Every Day,"
talking about the conservation of angular momentum,
and, since it's YouTube, cats:
(Video) Hey, it's me, Destin. Welcome back to "Smarter Every Day."
So you've probably observed that cats almost always land on their feet.
Today's question is: why?
Like most simple questions, there's a very complex answer.
For instance, let me reword this question:
How does a cat go from feet-up to feet-down in a falling reference frame,
without violating the conservation of angular momentum?
(Laughter)
JG: So, here's something all four of these videos have in common:
They all have more than half a million views on YouTube.
And those are people watching not in classrooms,
but because they are part of the communities of learning
that are being set up by these channels.
And I said earlier that YouTube is like a classroom to me,
and in many ways it is, because here is the instructor --
it's like the old-fashioned classroom: here's the instructor,
and then beneath the instructor are the students,
and they're all having a conversation.
And I know that YouTube comments have a very bad reputation
in the world of the Internet,
but in fact, if you go on comments for these channels,
what you'll find is people engaging the subject matter,
asking difficult, complicated questions that are about the subject matter,
and then other people answering those questions.
And because the YouTube page is set up so that the page in which I'm talking to you
is on the exact -- the place where I'm talking to you is on the exact same page
as your comments,
you are participating in a live and real and active way in the conversation.
And because I'm in comments usually, I get to participate with you.
And you find this whether it's world history,
or mathematics, or science, or whatever it is.
You also see young people using the tools and the sort of genres of the Internet
in order to create places for intellectual engagement,
instead of the ironic detachment
that maybe most of us associate with memes and other Internet conventions --
you know, "Got bored. Invented calculus."
Or, here's Honey Boo Boo criticizing industrial capitalism:
["Liberal capitalism is not at all the Good of humanity.
Quite the contrary; it is the vehicle of savage, destructive nihilism."]
In case you can't see what she says ... yeah.
I really believe that these spaces,
these communities, have become for a new generation of learners,
the kind of communities, the kind of cartographic communities
that I had when I was in high school, and then again when I was in college.
And as an adult, re-finding these communities
has re-introduced me to a community of learners,
and has encouraged me to continue to be a learner even in my adulthood,
so that I no longer feel like learning is something reserved for the young.
Vi Hart and "Minute Physics" introduced me
to all kinds of things that I didn't know before.
And I know that we all hearken back
to the days of the Parisian salon in the Enlightenment,
or to the Algonquin Round Table, and wish,
"Oh, I wish I could have been a part of that,
I wish I could have laughed at Dorothy Parker's jokes."
But I'm here to tell you that these places exist, they still exist.
They exist in corners of the Internet, where old men fear to tread.
(Laughter)
And I truly, truly believe that when we invented Agloe, New York, in the 1960s,
when we made Agloe real, we were just getting started.
Thank you.
(Applause)
