Paper towns and why learning is awesome John Green

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)

这是一张纽约州地图

,由 General Drafting Company 于 1937 年制作

这是制图迷中非常有名的地图

因为
在卡茨基尔山脉的底部,

有一个叫罗斯科的小镇——

实际上,
如果我把它放在这里会更容易——

有罗斯科,然后对了
罗斯科上方是纽约的罗克兰,

然后正上方
是纽约的小镇阿格洛。

纽约的阿格洛
对制图师来说非常有名,

因为它是一个纸镇。

它也被称为版权陷阱。

地图制作者——因为我的纽约
地图和你的纽约地图

看起来非常相似
,因为纽约的形状——

地图制作者通常会
在他们的地图上插入虚假的地点,

以保护他们的版权。

因为那样的话,如果我的假地点
出现在你的地图上,

我可以非常确定地
确定你抢劫了我。

Agloe
是制作这张地图的两个人

Ernest Alpers 和 Otto [G.] Lindberg 的首字母缩写

,他们于 1937 年发布了这张地图。

几十年后,Rand McNally 发布了一张

带有纽约 Agloe 的地图 ,
在偏僻

的两条土路
的完全相同的交汇处。

好吧,您可以想象
General Drafting 的喜悦。

他们立即打电话给
Rand McNally,说:

“我们抓到你了!
我们把纽约的阿格洛弄了起来

。那是个假地方。这是个纸城。

我们要告你脱裤子!”

兰德麦克纳利说,
“不,不,不,不,Agloe 是真实的。”

因为人们不断地
走向两条土路的交叉点——

(笑声)

在偏僻的地方,期待
那里有一个叫阿格洛的地方——

有人建了一个
叫阿格洛的地方,纽约。

(笑声)

它有一个加油站,一个杂货店,
最高峰时有两间房子。

(笑声

) 对于小说家来说,这当然是一个完全
无法抗拒的隐喻,

因为我们都愿意
相信我们写在纸上的东西

可以改变我们实际生活的现实世界

这就是为什么我的第三个 这本书
叫《纸城》。

但最终,
比发生这种情况的媒介更让我感兴趣的

是现象本身。

说世界
塑造了我们的世界地图很容易,对吧?

就像世界的整体
形状显然会影响我们的地图。

但我发现更有趣

的是我们
绘制世界的方式改变了世界。

因为如果北方倒台,世界将真的是
一个不同的地方。

如果阿拉斯加和俄罗斯不在地图的对立面,世界将是
一个真正不同的地方

如果我们预测欧洲
以实际规模展示它,世界将是一个不同的地方。

我们的世界地图改变了世界。

我们选择的方式——有点像
我们个人的制图事业,

也塑造了我们的生活地图

,进而塑造了我们的生活。

我相信我们所绘制的地图
会改变我们的生活。

我并不是说,在某些
秘密的奥普拉天使网络中,比如,

你可以想出你的方式——
摆脱癌症的感觉。

但我确实相信,虽然地图不会
告诉你你会去哪里,

但它们会告诉你你可能去哪里。

你很少去
不在你个人地图上的地方。

所以
当我还是个孩子的时候,我是一个非常糟糕的学生。

我的 GPA 一直在低 2s。

我认为我是
一个如此糟糕的学生的原因

是我觉得教育
只是

摆在我面前的一系列障碍,我必须

跳过才能达到成年。

而且我真的
不想跳过这些障碍,

因为它们似乎完全是
武断的,所以我经常不会,

然后人们会
威胁我,你知道,

他们会用这种
“持续 [我的] 永久 记录”

或“你永远找不到好工作。”

我不想要一份好工作!

据我所知,在十一
或十二岁的时候,

有好工作的人
一大早就起床,

(笑声)

有好工作的
人,他们做的第一件事

就是系一个勒死物品
脖子上的衣服。

他们真的给自己套上了绞索,

然后他们去上班,
不管他们是什么。

这不是幸福生活的秘诀。

这些人——在我痴迷于象征的
十二岁想象中——

这些人每天早上

做的第一件事就是扼杀自己

他们不可能快乐。

为什么我要
跳过所有这些障碍

并就此结束?

这是一个可怕的结局!

然后,当我上十年级的时候,
我去了阿拉巴马州伯明翰郊外的这所学校,

印第安泉学校,这
是一所小型寄宿学校

一下子我变成了一个学习者。

我成为了一名学习者,
因为我发现自己

身处一个学习者社区。

我发现自己被

那些崇尚理性主义和敬业精神的人包围着

,他们认为我那
讽刺的、太酷的

脱离接触并不聪明,也不有趣

,但就像是

对非常复杂
和引人注目的问题的一种简单而平淡无奇的回应。

于是我开始学习,
因为学习很酷。

我了解到一些无限
集比其他无限集更大,

并且我了解到五步抑扬格是
以及为什么它听起来对人耳如此好。

我了解到内战
是一场国有化的冲突,

我学到了一些物理学知识,

我了解到相关性不
应该与因果关系相混淆——

顺便说一句,所有这些都

丰富
了我每天的生活。

确实,我不会将
它们中的大多数用于我的“工作”,

但这不是我的目的。

这是关于制图的。

制图流程是怎样的?

你知道,
在某块土地上航行,然后想,

“我想我会画那片土地”

,然后想知道,“也许
还有更多的土地可以画。”


是我真正开始学习的时候。

的确,我有
老师没有放弃我

,我很
幸运有这些老师,

因为我经常让他们有理由认为
没有理由投资我。


我在高中所做的很多学习

不是关于课堂内发生的事情

而是关于
课堂外发生的事情。

例如,我可以告诉

你“
冬天的午后有某种偏光——

那压抑,就像
大教堂曲调的重量——”

不是因为我
在高中时在学校记住了艾米丽·狄金森

而是因为那里
我上高中的时候是个女孩

,她的名字叫阿曼达
,我很喜欢她

,她喜欢艾米莉狄金森的诗。

我之所以能告诉你
什么是机会成本,

是因为有一天
我在沙发上玩《超级马里奥赛车》时,

我的朋友艾米特走进来,他说:

“你玩《
超级马里奥赛车》多久了?”

我说,“我不知道,
比如,六个小时?” 他说:

“你知道吗,如果你
在巴斯金罗宾斯工作了六个小时,

你本可以赚到 30 美元,
所以在某些方面,

你只需花 30 美元
就可以玩《超级马里奥赛车》。”

我当时想,“我会接受这笔交易。”

(笑声)

但我知道什么是机会成本。

一路走来,
我的生活地图变得更好。

它变大了; 它包含更多的地方。

可能会发生更多的事情,

我可能拥有更多的未来。

这不是一个正式的、有组织的
学习过程

,我很高兴承认这一点。

它参差不齐,前后矛盾,
有很多我不知道的。

我可能知道,你知道,康托尔的想法

,即一些无限集
比其他无限集大,

但我并不真正理解
这个想法背后的微积分。

我可能知道机会成本的概念,

但我不知道
收益递减规律。

但是,将学习想象
成制图学,

而不是把它想象

你必须跳过的任意障碍,最大的好处

是你看到了一点海岸线
,这让你想看到更多。

所以现在我
至少

知道了构成所有这些东西的一些微积分。

所以,我在高中时有一个学习社区

,然后我去
了另一个上大学,

然后我又去了另一个,

当我开始
在一家名为“书单”的杂志工作时

,我是一名助理,周围
都是令人惊讶的博学 人们。

然后我写了一本书。

就像所有作家梦寐以求的那样,

我立即辞掉了工作。

(笑声)

自高中以来,我第一次

发现自己没有学习
社区,这很痛苦。

我讨厌它。 在这两年的时间里

,我读了很多很多书

我读过关于斯大林的书,

还有关于乌兹别克人
是如何认定为穆斯林的

书,我也读过关于
如何制造原子弹的书,

但我感觉就像我在设置
自己的障碍,

然后自己跳过它们,
而不是 感受到成为

学习者社区的一员的兴奋,这是一个

共同
参与制图事业

的人社区,试图更好地理解
和绘制我们周围的世界。

然后,在 2006 年,我遇到了那个人。

他叫泽弗兰克。

我并没有真正认识他,
只是在网上认识的。

泽弗兰克当时正在运行
一个名为“泽弗兰克的表演”的节目

,我发现了这个节目

,那是我
重新成为社区学习者的方式。

Ze 谈到了拉斯维加斯

:(视频)Ze Frank:拉斯维加斯建
在巨大而炎热的沙漠中。

这里几乎所有的东西都是
从其他地方带来的——

岩石、树木
、瀑布。

这些鱼几乎和
我那会飞的猪一样格格不入。

与这个地方周围灼热的沙漠形成鲜明对比的

是,这些人也是如此。

来自世界各地的事物在
这里被重建,远离它们的历史

,远离
以不同方式体验它们的人们。

有时会做出改进——
甚至狮身人面像也做了鼻子整形。

在这里,没有理由
觉得您缺少任何东西。

这个纽约对我
和其他人一样重要。

一切都脱离了上下文,这
意味着上下文允许一切:

自助停车、活动中心、鲨鱼礁。

这种地方的制造可能
是世界上最伟大的成就之一,

因为没有人属于这里;
每个人都这样做。

今天早上我四处走走时,
我注意到大多数建筑物

都是巨大的镜子,
将太阳反射回沙漠。

但与大多数镜子不同,

这些镜子向您展示
自己嵌入某个地方的外部视图,

这些镜子返回时是空的。

John Green:让我
怀念那些

可以
在在线视频中看到像素的日子。

(笑声)

泽不仅是一位伟大的公共知识分子,
他还是一位出色的社区建设者,

围绕这些视频建立起来

的社区在很多方面都是一个学习者社区。

所以我们在国际象棋上合作玩了泽弗兰克
,我们打败了他。

我们组织自己带一个年轻人
在美国进行公路旅行。

我们把地球变成了一个三明治

,让一个人
在地球上的一个

点拿着一块面包,在地球的

另一端,让另一个人
拿着一块面包。

我意识到这些都是愚蠢的想法,
但它们也是“学习”的想法

,这就是让我兴奋的地方

,如果你上网,你可以
在任何地方找到这样的社区。

关注 Tumblr 上的微积分标签

,是的,你会看到人们
抱怨微积分,

但你也会看到人们
重新发布这些抱怨,

提出微
积分有趣和美丽的论点

,这是思考微积分的一种方式
你觉得无法解决的问题。

你可以去 Reddit 之类的地方
,找到子 Reddit,

比如“问历史学家”或“问科学”

,在那里你可以问
这些领域

的人各种各样的问题,

从非常严肃的问题到非常愚蠢的问题 .

但对我来说

,目前在互联网上成长起来的最有趣的学习者社区
是在 YouTube 上

,诚然,我有偏见。

但我认为在很多方面
,YouTube 页面就像一个教室。

以“分钟物理”为例,这

是一个
向世界教授物理知识的人

:(视频)让我们切入正题。

截至 2012 年 7 月 4 日,希格斯玻色子

粒子物理学标准模型中最后一个
通过实验发现的基本部分。

但是,你可能会问,
如果希格斯玻色子在 1970 年代还没有被发现,为什么

还要将其
与电子、光子和夸克等著名粒子一起包含在标准模型中

好问题。 有两个主要原因。

首先,就像电子
是电子场中的激发物一样

,希格斯玻色子只是一个粒子
,它是

无处不在的希格斯场的激发物。

希格斯场反过来

在我们的弱核力模型中起着不可或缺的作用。

特别是,希格斯场
有助于解释为什么它如此微弱。

我们将
在稍后的视频中详细讨论这一点,

但即使弱核理论
在 1980 年代得到证实,但在方程中

,希格斯场
与弱力如此密不可分,以至于直到现在

我们都无法证实
其真实而独立的存在。

JG:或者这是我在

节目“速成班”中制作的一段视频,
谈论第一次世界大战

:(视频)直接
原因当然是 1914 年 6 月 28 日在萨拉热窝遇刺

的奥地利大公弗朗茨·费迪南德

,由一位
名叫 Gavrilo Princip 的波斯尼亚塞族民族主义者撰写。

顺便说一句:值得注意的是

,20 世纪的第一次大战

始于恐怖主义行为。

所以弗朗茨·费迪南德
并不是特别

受到他的叔叔弗朗茨·约瑟夫皇帝的喜爱——
现在那是胡子!

但即便如此,刺杀事件导致奥地利
向塞尔维亚发出最后通牒,

塞尔维亚接受
了奥地利的部分要求,但不是全部,

导致奥地利
向塞尔维亚宣战。

然后,由于
与塞尔维亚人结盟,俄罗斯动员了军队。

德国因为
和奥地利结盟,

告诉俄罗斯停止动员

,俄罗斯没能做到,于是德国
调动了自己的军队,

对俄罗斯宣战,
与奥斯曼结盟,

然后对法国宣战,
因为 ,你知道,法国。

(笑声

) 人们选择通过 YouTube 学习的不仅仅是物理
和世界历史

这是一个关于抽象数学的视频。

(视频)所以你就是我,你又
上数学课了,

因为它们让你每天都去。

你正在学习,我不知道,
无穷级数的总和。

这是高中的话题吧?

这很奇怪,因为这是一个很酷的话题,
但无论如何他们还是设法毁掉了它。

所以我想这就是为什么他们
在课程中允许无限系列。

所以,在一个完全可以理解
的分散注意力的需要中,你在涂鸦

和思考
“series”的复数应该是什么,而

不是手头的话题:
“serieses”、“seriese”、“seriesen”和“serii? "

还是单数应该
改变:一个“serie”或“serum”

,就像“sheep”的单数
应该是“shoop”一样。

但是

像 1/2 + 1/4 + 1/8 + 1/16 等等这样的东西的整个概念
接近一个,如果

你想画一条大象线,

每个大象都握着下一个大象的尾巴 一:

普通大象、小象、
小象、狗大小的大象、

小狗大小的大象,
一直到Tusks先生甚至更远。

这至少有点令人敬畏,

因为您可以
在一行中获得无限数量的大象,

并且仍然可以将它放在
单个笔记本页面上。

JG:最后,Destin
来自“Smarter Every Day”,

谈论
角动量守恒

,因为是 YouTube,猫

:(视频)嘿,是我,Destin。
欢迎回到“更聪明的每一天”。

所以你可能已经观察到猫
几乎总是用脚着地。

今天的问题是:为什么?

像大多数简单的问题一样,
有一个非常复杂的答案。

例如,让我改写这个问题:

猫如何
在下落的参考系中从双脚向上移动到双脚向下,

而不
违反角动量守恒?

(笑声)

JG:所以,这
四个视频都有一个共同点:

它们
在 YouTube 上的浏览量都超过了 50 万。

这些人
不是在教室里观看,

而是因为他们是这些渠道建立
的学习社区的一部分

我之前说过,YouTube
对我来说就像一个教室

,在很多方面它都是,
因为这里有老师——

就像老式的教室:
这里有老师,

然后在老师下面
是学生

,他们 ‘都在交谈。

而且我知道 YouTube 评论

在互联网世界中的名声很差,

但事实上,如果你继续
为这些频道发表评论,

你会发现人们
参与主题,

提出困难、复杂的
问题 关于主题,

然后其他人
回答这些问题。

而且因为 YouTube 页面的设置是为了
让我与您交谈的页面与您

的评论完全相同——我
与您交谈的位置与您的评论在完全相同的页面上

您正在参与一个 以活生生、
真实主动的方式进行对话。

而且因为我经常发表评论,
所以我可以和你一起参与。

无论是世界历史

、数学、科学
还是其他任何东西,你都会发现这一点。

您还看到年轻人使用互联网的工具
和类型

来创造
知识参与的场所,

而不是

我们大多数人可能与模因
和其他互联网惯例相关的讽刺性超然——

你知道,“感到无聊 . 发明了微积分。

或者,这里是批评工业资本主义的 Honey Boo Boo

[“自由资本主义根本不是
人类的善。

恰恰相反;它
是野蛮的、破坏性的虚无主义的工具。”

] 如果你看
不到她说的话。 .. 是的。

我真的相信这些空间,

这些社区,已经
成为新一代的学习者

,那种社区,

那种我在高中时拥有的制图社区,
然后在我上大学时再次出现。

作为一个成年人,重新找到
这些社区

让我
重新认识了一个学习者社区,

并鼓励
我即使在成年后也要继续学习,

所以我不再
觉得学习是年轻人的事 .

Vi Hart 和“Minute Physics”向我介绍

了我以前不知道的各种事物。

而且我知道我们都回想起启蒙运动

时期的巴黎
沙龙,

或者阿尔冈昆圆桌会议的日子,并希望,

“哦,我希望我能成为
其中的一部分,

我希望我能
笑 多萝西·帕克的笑话。”

但我在这里告诉你,这些地方
存在,它们仍然存在。

它们存在于互联网的角落
,老人们不敢涉足。

(笑声)

我真的,真的相信,当
我们在 1960 年代发明纽约的 Agloe 时,

当我们让 Agloe 成为现实时,
我们才刚刚开始。

谢谢你。

(掌声)
