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
=======
This is a list of spacecraft powered by non-rechargeable batteries. While most spacecraft are powered by longer-lasting power sources such as solar cells or radioisotope thermoelectric generators, which can provide power for years to decades, some have been powered by primary (non-rechargeable) electrochemical cells, which provide runtimes of minutes to months. This is typically done only on spacecraft that are planned to operate for only a short time, even if they must travel for a long time before being activated. Some spacecraft classes where this applies are atmospheric probes, short-duration landers, and technology demonstrators. Some early Earth satellites, such as the first Sputnik and Explorer satellites, also used primary batteries, before solar panels were widely adopted.
