Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Polavision was an "instant" color home movie system launched by Polaroid in 1977.
Unlike other motion picture film stock of the time, Polavision film reproduces color by the additive method, like the much earlier Dufaycolor film. In essence, it consists of a black-and-white emulsion on a film base covered with microscopically narrow red, green and blue filter stripes. It was instant in the sense that it could be very quickly and easily developed in the Polavision processing unit after it was removed from the Polavision camera, ready for viewing in only a few minutes.
The Polavision cartridge is a small rectangular box containing the film reels and a small lens and prism for projection at an open gate. The film format is similar to the super 8 mm format, but without the Polavision tabletop viewer the only way a Polavision film can be shown is by destroying the cartridge and projecting the removed film with an ordinary super 8 mm projector or transferring it to video with a telecine system.
The Polavision system was a major commercial failure, and was discontinued in 1979. However, the underlying technology was improved and used as the basis for the Polachrome instant color transparency system introduced in 1983.
