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
=======
In a traditional nuclear photonic rocket, an onboard nuclear reactor would generate such high temperatures that the blackbody radiation from the reactor would provide significant thrust.  The disadvantage is that it takes a lot of power to generate a small amount of thrust this way, so acceleration is very low.  The photon radiators would most likely be constructed using graphite or tungsten.  Photonic rockets are technologically feasible, but rather impractical with current technology based on an onboard nuclear power source.  However, the recent development of Photonic Laser Thruster (PLT), the Beamed Laser Propulsion (BLP) with photon recycling, promises to overcome these issues by separating the nuclear power source and the spacecraft and by increasing the thrust to nuclear power ratio (specific thrust) by orders of magnitude.
