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
=======
RAFGL, the "Revised Air Force Geophysical Laboratory" (S.D. Price and T.L. Murdock, 1983), is a four-color infrared sky survey catalog. It contains measurements at 4.2, 11.0, 19.8 and 27.4 micron of 2,970 sources, obtained with sounding rockets, in combination with some ground-based data.
The catalog includes most of the AFCRL (Air Force Cambridge Research Lab) with the same number, omitting unconfirmed sources, and also, 306 new sources of the southern hemisphere, numbered from 
4001 to 4306. It also gives updated positions and more accurate results.
