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
=======
The Perkins Brailler is a "braille typewriter" with a key corresponding to each of the six dots of the braille code, a space key, a backspace key, and a line space key.  Like a manual typewriter, it has two side knobs to advance paper through the machine and a carriage return lever above the keys.  The rollers that hold and advance the paper have grooves designed to avoid crushing the raised dots the brailler creates.
Although braille notation was designed for people who are blind or visually impaired to read, prior to the introduction of the Perkins Brailler, writing braille was a cumbersome process. Braille writers created braille characters with a stylus and slate (as developed by Louis Braille) or by using one of the complex, expensive, and fragile braille writing machines available at the time.
