Imagination

It's interesting that some people find science so easy, and others find it kind of dull and difficult
Especially kids, you know some of them you know are just eat it up
And I don't know why it is
It's the same perhaps for (mumble)
For instance, lots of people love music, and I never could carry a tune
I lose a great deal of pleasure out of that
And I think people lose a lot of pleasure who find science dull
In the case of science, I think that one of thе things that make it very difficult
It takes a lot of as imagination

[Chorus]
It takеs a lot of imagination
(It takes a lot of imagination)
It's very hard to imagine all the crazy things that things really are like
It takes a lot of imagination
(It takes a lot of imagination)
It's very hard to imagine all the crazy things that things really are like

Nothing is really as it seems
We're used to get hot and cold, and all that hot and cold is, is the speeds that the atoms are jiggling
If they jiggle more it corresponds to hotter and colder is jiggling less
So, if you have a cup of coffee or something sitting on a table
And the atoms are jiggling a great deal in the cup, and they bounce against the cup, then the cup then gets shaky
And the atoms in the cup shake, and they bounce against the source and the heat, heats the cup and heats everything else
Hot thing spreads its heat into other things by mere contact because the atoms that are jiggling a lot in the hot thing
Shake the ones that are jiggling only a little bit, in the cold thing, so that the heat we say goes into the cold thing, it spreads
But what's spreading is just jiggling, and irregular motions
Which is easy... to kind of understand
(To kind of understand)

[Chorus]
It takes a lot of imagination
(It takes a lot of imagination)
It's very hard to imagine all the crazy things that things really are like
It takes a lot of imagination
(It takes a lot of imagination)
It's very hard to imagine all the crazy things that things really are like

And if you’re used to balls bouncing, you know they slow up and stop after a while
But we have to imagine with the atoms a perfect elasticity
They never lose any energy, every time they bounce, they keep on bouncing
They’re perpetually moving
And that the things that are happening when we say something loses energy, if a ball comes down and bounces
It shakes irregularly some of the atoms in the floor
And then when it comes up again, it leaves some of those atoms moving, jiggling
So, as it bounces, it’s passing its extra energies, it's extra motions to little patches on the floor each time it bounces, and loses a little each time
Until it settles down, we say as the falling motion stops
But what's left is the floor is shaking more than it was before, and the atoms in the ball are shaking more than they were before
That the organized motion of all these atoms is moving the same way falling down and the quiet floor is now transformed into a ball sitting on the ground
But all that motion is still there in a form, in the form of the jiggling of the floor, which is a little bit warmer
But anybody who's hammered a great deal on something knows that it's true, that if you pound something, you can feel the temperature difference, it heats up
It heats up something because you're jiggling

[Chorus]
It takes a lot of imagination
(It takes a lot of imagination)
It's very hard to imagine all the crazy things that things really are like
It takes a lot of imagination
(It takes a lot of imagination)
It's very hard to imagine all the crazy things that things really are like

This picture of atoms, is a beautiful one that you can keep looking at all kinds of things this way
I find myself trying to imagine all kinds of things all the time
And I get a kick out of it just like a runner gets a kick out of sweating
I get a kick out of thinking about these things
I can't stop, I mean I could talk forever
