Just How Small is an Atom?

Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.

Lesson by Jonathan Bergmann, animation by Cognitive Media.

By watching this video atoms are learning about

[Ellenchattergirl]

Fun facts:
1.) There are 7 octillion atoms in a human body.
2.) If there was no empty space between atoms, the entire human population could fit into an apple.

I like how the narrator thought Imperial units would be easier to understand than Metric

The way he talk, Disney should create a character of him

Lets split the atom an half they said!
It will be fun they said!

[BAGELMENSK]

this video is weirdly disturbing, just in how it's

[kevinpham]

The world is basically mostly empty space?

[emmavrijburg]

I remember having an existential crisis during chemistry once when I first learned “nothing” is between the nucleus and the electrons.
I came home and I was all like “everything is empty, I’m empty, the universe is empty. We’re all just chucks of somethings floating around in pure nothingness”

Oh wait, what are atoms made of?
"Quarks"
How small are they?
"5.2 yactometers"

[jacobmartin]

The density thing really blew my mind. This was very well put together. 👍

To understand small things we compare it with big things
And to understand big things we compare it with small ones
😂😂

A 5 minute video taught me more than 5 hours worth of classes back in highschool.

[manny]

People who study atoms are just a lot of atoms trying to figure out what they are made of.

The switch in animation style at 1:14 almost gave me an epileptic seizure...

3:20 gg this will bring back harambe <3

*"But- I bet you've never really thought about how small atoms are"*
Me, who's had existential crisis because I think about it so much:
*"i w i l l f i g h t y o u"*

I remember me at the age of 7, watching this same video, thinking Kg/m cubed and lb/ft cubed are like advanced mathematics symbols that only the top-tier scientists use...

After watching this I have learned




The earth is a grapefruit?

[planetdesign]

Guy: *holds atom in fingers*
Atom: *Snaps in half*
Guy: Oh fu-

[Meclarence]

The atom is still bigger, than the size of a lot of people's brains in the comment section.
