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
=======
Nickel sulfide  is an inorganic compound with the formula NiS.  It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide.  Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.  Aside from being useful ores, nickel sulfides are the products of desulfurization reactions, and are sometimes used as catalysts.  Nonstoichiometric forms of nickel sulfide are known, e.g., Ni9S8 and Ni3S2.
