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
=======
Nuclear power in space is the use of nuclear power in outer space, typically either small fission systems or radioactive decay for electricity or heat. Another use is for scientific observation, as in a Mössbauer spectrometer. One common type is a radioisotope thermoelectric generator, which has been used on many space probes and on manned lunar missions, and another is small fission reactors for Earth observation satellites such as the TOPAZ nuclear reactor. A radioisotope heater unit provides heat from radioactive decay of a material and can potentially produce heat for decades.Russia has sent about 40 reactors into space and its TOPAZ-II reactor can produce 10 kilowatts. The Romashka reactor family uses uranium and direct thermoelectric conversion to electricity, rather than using a heated fluid to drive a turbine. The United States tested a nuclear reactor in space for 43 days in 1965. While not yet tested in space, the test of the Demonstration Using Flattop Fission (DUFF) on September 13, 2012 was the first test of a nuclear reactor power system for space since then.Examples of nuclear power for space propulsion systems include nuclear electric rocket (nuclear electric propulsion), radioisotope rocket, and radioisotope electric propulsion (REP). One of the more explored is the nuclear thermal rocket, which was tested in the NERVA program. See also Category:Nuclear spacecraft propulsion (category link). Nuclear pulse propulsion was the subject of Project Orion (nuclear propulsion)
