1
The universe is pretty big and very strange.
2
Hundreds of billions of galaxies with sextillions of stars and planets
3
and in the middle of it all there's Earth with you and us.
4
But as enormous as the universe seems looking up,
5
it seems to get even larger when you start looking down.
6
You are towering over worlds within worlds within worlds,
7
each in plain sight and yet hidden from your experience experience.
8
Let's go on a journey.
9
We'll start in a park about a thousand meters long enough for a 15 minute walk.
10
Every time we click this magic button will become a thousand times smaller.
11
Please slip into this magic science suit so you don't die and can still see.
12
Ready?
13
Let's go!
14
The miniature realm.
15
You are the size of a grain of sand just two millimeters high,
16
standing on a blade of grass that seems as tall as an eight-story building to you.
17
A square meter of lawn is now a dense metropolitan area with 100,000 blades or two Manhattan's worth of grass towers.
18
From your new tiny perspective,
19
the park that you could quickly stroll through before is now the size of France.
20
Crossing it would take at least a week.
21
Human-sized humans loom over you,
22
four times taller than the Empire State Building,
23
their steps falling from horizon to horizon.
24
A bee the size of a helicopter lands near you,
25
making the ground shake as its hairy carapace vibrates with each wingbeat.
26
You try to escape, but are barely able to move because the air is so gooey.
27
Before you click the button,
28
air resistance was barely noticeable,
29
But as you're now a thousand times smaller,
30
it's as if the air has become a thousand times denser.
31
It feels like you're moving through honey.
32
Flying insects like bees use this to their advantage.
33
Their wings are not made for gliding,
34
but like paddles that row through the air.
35
Scaled up to human size,
36
the bee would outrun a Concorde jet,
37
except it couldn't even take off because it would be too heavy for its wings.
38
The microscopic realm.
39
You've entered the microscopic realm and are now less than 2 micrometers tall,
40
about the size of an E coli bacteria.
41
From your new tiny perspective,
42
the park you started in is now a million kilometers wide to you.
43
If you walked non-stop, it would take some 25 years to cross it.
44
It's hard to grasp just how huge the microscopic world is to its tiny inhabitants.
45
The giant bee that was close a moment ago is now the size of Mount Everest,
46
towering high into the sky,
47
but alive, humming and vibrating.
48
The air here feels almost solid to you.
49
On the human scale it would be as viscous as lava,
50
extremely hard to push through.
51
The blade of grass now expands so far you can't see its edges,
52
stretching as wide as parrots would to a regular-sized human.
53
You see valleys that look like dried-up riverbeds,
54
dead patches like deserts, and giant craters left behind by voracious aphids.
55
But if you look closely, this is not terrain.
56
These are rows of individual cells,
57
each the size of a house with hard exteriors like glass shells.
58
Every few cells there are huge openings called stomata,
59
like mouths sucking in air and blowing out oxygen.
60
Suddenly, the gigantic bee begins to move.
61
A construct made of rigid pieces that slide against each other like a suit of armor.
62
It takes off to escape a drop of water the size of an asteroid
63
that fell from another blade of grass and is now rushing at you at breathtaking speeds.
64
You brace for impact, but instead of feeling a strong punch,
65
you just get sucked in.
66
You try to swim, but the water feels thick and sticky and holds onto your limbs like glue.
67
Air molecules are free spirits,
68
while water molecules act more like social creatures that group together whenever possible.
69
They pull on each other and create a relatively strong cohesive force that traps you.
70
You can't help it, but you're still moving,
71
tumbling in all directions, helplessly dragged along by an invisible current.
72
Floating in this miniature lake are tens of thousands of microorganisms.
73
They take on many forms.
74
Viruses the size of tennis balls float around you aimlessly.
75
Others like Euglena oxyuricils pass you like freight trains.
76
But most look like oily jellyfish the size of a car,
77
sporting long tentacles that act like supercharged propellers.
78
Despite the water holding onto them like glue,
79
some move hundreds of body lengths per second,
80
equivalent to a person shovelling through mud at over 600 kilometers an hour.
81
However bacteria weigh so little and water is so viscous that they basically have no inertia,
82
there is no gliding on this scale.
83
The result is a weird jerky motion that's hard to keep track of.
84
Maybe we can learn more about this strange motion if we go even deeper.
85
The Molecule Realm You've become the size of a molecule,
86
just under 2 nanometers wide.
87
At your new tiny scale,
88
the droplet now seems as big as the moon to a regular human.
89
The blade of grass it rests on could reach from the tip of Alaska to the end of Australia,
90
and the park is now almost the size of the solar system.
91
But instead of mostly empty space,
92
it is filled with stuff.
93
Everywhere you look there are innumerable amounts of molecules and atoms.
94
The rigid walls of the grass cells beneath you are clearly vibrating,
95
rippling with waves of energy.
96
The water droplet contains nearly a sextillion water molecules that are all in motion.
97
Water is actually a storm of H2O molecules smashing into each other hundreds of trillions of times a second.
98
Each of them is moving at speeds of around 2300 kilometers an hour and bombard their surroundings mercilessly,
99
sending small objects hurtling in all directions.
100
This is the source of the invisible current that you noticed when you were a thousand times larger.
101
Scaling this speed up to the human scale is impossible,
102
as a human-sized molecule would be two thousand times faster than the speed of light.
103
All this furious motion comes from heat.
104
Heat is a bit abstract at our human scale,
105
where you touch something and get a vague sense of whether it's hot or cold.
106
But down here, you really feel what heat is.
107
motion of molecules, vibrating, twisting and colliding as if they're inside a furious ball pit.
108
When these molecules lose heat,
109
they move more slowly and collide less often.
110
When they gain heat, they speed up and smash together with renewed fervor.
111
Temperature is basically the measure of the average speed of these fantastic dancers performing all day.
112
Suddenly, a molecule hits you especially hard,
113
and you're catapulted out of the water droplet into the air again.
114
But here, you see something unexpected.
115
The stuff between the air molecules.
116
Nothing.
117
Between the molecules that make up the air, there is a vacuum.
118
On average, a molecule in the air travels for about 60 nanometers,
119
which is about the length of a hockey rink if it were the size of a human.
120
If we were to compress all the molecules and atoms buzzing around in the room you're watching this in,
121
they would only fill about 0.1% of its volume.
122
99.9% of the space around you is a vacuum.
123
You just don't notice it.
124
Which also means that every time you take a breath,
125
you breathe in mostly nothing with a few atoms.
126
The subatomic realm.
127
At your size of under two picometers,
128
scale starts to lose its meaning.
129
A human would be nearly two billion kilometers tall relative to you,
130
so large they could stretch their arms from the Sun to Saturn.
131
An atomic nucleus would be the size of a grain of sand you could hold on the tip of your finger.
132
That grain holds 99.97% of the atom's mass.
133
The rest, a sphere of influence about as large as the Eiffel Tower from your perspective,
134
is filled with an electron cloud.
135
That's basically all the places where electrons might be at any given moment in time.
136
Electrons are shape-shifters that morph around outside a nucleus,
137
creating a new and vibrating mess of different shapes with every new moment.
138
Unlike the graceful motion of planets,
139
the atomic nuclei are chaotic blurs.
140
They bulge, roll, quiver and breathe.
141
They hold back the same energy that powers nuclear bombs and it doesn't let them sit still.
142
They twist and vibrate six-stillions of times a second.
143
It's time to end our journey and return to… What are you doing?
144
Stop it!
145
The smallest place… We have reached the bottom,
146
the border between reality and unreality.
147
The scale here is the Planck length,
148
which is the distance light travels in a Planck time.
149
Planck time is the time it takes light to travel a Planck length.
150
Hmm, okay, none of our models of the universe make sense at scales smaller than this,
151
so for now, this is it.
152
We think that down here,
153
particles bubble into existence and then spontaneously disappear,
154
creating a quantum foam of unimaginable energy.
155
Can we go even smaller?
156
We don't know.
157
It's time to return.
158
The universe is a large and strange If you look up,
159
the universe is large and strange.
160
So incredibly large and strange.
161
But if you look down into the tiny and extremely tiny,
162
the universe seems even larger and even stranger.
163
In the end, the perfect place might be where you are right now.
164
Not too big, not too small.
165
This bird has magical powers.
166
Let's see a demonstration.
167
Bring in the latest scientific research.
168
Wow, that's a lot of complicated stuff about the immune system and all its cells.
169
How could someone possibly understand all of this?
170
Incredible!
171
This overview is delightful and easy to grasp, but still scientifically accurate.
172
Let's make it a bit more difficult.
173
Can she make all of evolution visible at a glance?
174
This is brilliant!
175
You can clearly see the relationships between species and how they evolved.
176
And look at those illustrations!
177
These posters are ready to be shared with the world.
178
These very special pieces of Kurzgesagt are now available on our shop along with many other sciency products,

คู่มือการติดตามการพูดแบบขั้นตอน
การเรียนภาษาอังกฤษจากยูทูปมีประสิทธิภาพมากขึ้นเมื่อคุณใช้เทคนิคการฝึกพูดตาม (shadowing). ต่อไปนี้คือขั้นตอนในการดำเนินการจากวิดีโอนี้:
- เริ่มจากการฟังวิดีโออย่างละเอียดครั้งแรกเพื่อเข้าใจบริบทและข้อความโดยรวม
- ฟังซ้ำในครั้งที่สอง ขณะเดียวกันให้เปิดปากพูดตามความเร็วของผู้บรรยาย
- ให้เน้นเสียงและการออกเสียงของวลีที่สำคัญ เช่น “Let's go on a journey.”
- ใช้เทคนิค shadowspeaks โดยการเน้นคำสำคัญและพยายามเลียนแบบการเปล่งเสียงและอารมณ์การพูด
- สุดท้าย ให้ทดลองพูดวลีทั้งชุดโดยไม่ดูวิดีโอ เพื่อตรวจสอบความเข้าใจและความกระชับในการพูด
การใช้เทคนิคนี้คุณจะสามารถพัฒนาทักษะการพูดและการฟังในภาษาอังกฤษได้อย่างมีประสิทธิภาพ โดยเฉพาะอย่างยิ่งถ้าคุณเข้าร่วมกับชุมชนใน shadowspeak หรือ shadowing site ที่จะช่วยเสริมสร้างความมั่นใจในการพูดของคุณ
เทคนิค Shadowing คืออะไร?
Shadowing เป็นเทคนิคการเรียนรู้ภาษาที่ได้รับการรับรองทางวิทยาศาสตร์ พัฒนาขึ้นสำหรับการฝึกนักแปลมืออาชีพ วิธีการนี้เรียบง่ายแต่ทรงพลัง: คุณฟังเสียงภาษาอังกฤษจากเจ้าของภาษาและพูดตามทันที — เหมือนเงาที่ตามผู้พูดด้วยช่วงเวลาห่าง 1-2 วินาที การวิจัยแสดงว่าเทคนิคนี้ปรับปรุงความแม่นยำในการออกเสียง ทำนองเสียง จังหวะ การเชื่อมเสียง การฟังเข้าใจ และความคล่องแคล่วในการพูดได้อย่างมีนัยสำคัญ
