This is important. This is very cool: Symphony of Science - the Quantum World!

A musical investigation into the nature of atoms and subatomic particles, the jiggly things that make up everything we see. Featuring Morgan Freeman, Stephen Hawking, Michio Kaku, Brian Cox, Richard Feynman, and Frank Close.

The Quantum World is the eleventh installment in the ongoing Symphony of Science music video series.

Lyrics:

[Morgan Freeman]
So, what are we really made of?
Dig deep inside the atom
and you'll find tiny particles
Held together by invisible forces

Everything is made up
Of tiny packets of energy
Born in cosmic furnaces

[Frank Close]
The atoms that we're made of have
Negatively charged electrons
Whirling around a big bulky nucleus

[Michio Kaku]
The Quantum Theory
Offers a very different explanation
Of our world

[Brian Cox]
The universe is made of
Twelve particles of matter
Four forces of nature

That's a wonderful and significant story

[Richard Feynman]
Suppose that little things
Behaved very differently
Than anything big

Nothing's really as it seems
It's so wonderfully different
Than anything big

The world is a dynamic mess
Of jiggling things
It's hard to believe

[Kaku]
The quantum theory
Is so strange and bizarre
Even Einstein couldn't get his head around it

[Cox]
In the quantum world
The world of particles
Nothing is certain
It's a world of probabilities

(refrain)

[Feynman]
It's very hard to imagine
All the crazy things
That things really are like

Electrons act like waves
No they don't exactly
They act like particles
No they don't exactly

[Stephen Hawking]
We need a theory of everything
Which is still just beyond our grasp
We need a theory of everything, perhaps
The ultimate triumph of science

(refrain)

[Feynman]
I gotta stop somewhere
I'll leave you something to imagine

Imagining Floating Rocket Trains

Future Rocket Train, H. W. McCauley - Amazing Stories, January 1939 (Back Cover)

A floating rocket train - excited about the magnetic properties of cobalt steel, the folks at Amazing Stories envisioned the possibility of this futuristic mode of transportation. Note the streamlined auto designs and the Art Deco style of the building on the lower left - all part of the fascinating design culture of the 1930s.

The Land Of Physics - Think Of It As A Map To An Excellent Action Adventure Game

Central Scientific's 1939 Map of Physics (image via Frank Jacobs)
This spatial representation of the subject, dating from 1939, defines itself as Being a map of physics, containing a brief historical outline of the subject as will be of interest to physicists, students, laymen at large; Also giving a description of the land of physics as seen by the daring souls who venture there; And more particularly the location of villages (named after pioneer physicists) as found by the many rivers; Also the date of founding of each village; As well as the date of its extinction; and finally a collection of various and sundry symbols frequently met with on the trip.
The map represents physics as a continent with its main branches as rivers. The districts are populated with villages named after famous physicists, with the relation between those pioneers and their field of expertise.

Those fields are, left to right and top to bottom: Mechanics, Sound, Electricity, Magnetism, Light, Astronomy, Heat, Mechanical and Electromagnetic Energy, and Radioactivity.

Displaying the fields as topographical elements of the same map hints at the unified nature of the subject. Some examples: '[T]he joining of astronomy and mechanics […] by Kepler, Galileo and Newton (who showed that the movement of the Moon is described by the same laws as [that of] a falling apple.' At the center of the map, mechanics and electromagnetism merge. 'Electromagnetism [itself is] a fusion between electricity and magnetism, which were joined when it was noted by Oersted that an electric current produces a magnetic field, and when it was noted by Faraday that when a magnet is moved around in a wire loop, it creates a current in that loop.' (Description via Frank Jacobs)

So, think of it this way: if you can memorize the geography of lands or cities represented in the typical action adventure video game, you can more easily conceptualize the world of physics with the study of this map. I would suggest this to educators teaching the basics of physics and/or any of the specific fields.
