VR may cause vomiting – Because of motion sickness
VR may cause vomiting – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses. This is also the reason why
many virtual reality users can cause problems with motion sickness. Then the impressions
received by the liar do not agree with the visual stimulus. In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.
Eyes see the perfect simulation of space, covering the entire field of view.
However, the brain does not record any motion signals from the labyrinth or other senses.
In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.

3d printing in space
3d printing in space – In recent years, significantly improved technologies for printing three-dimensional objects that are already much cheaper. The company Made in Space has launched a project. Allowing to print 3D components, directly on orbit.
GPS system – It uses 31 satellites orbiting the Earth. Each is equipped with an atomic clock and emits signals in which encoded is its location and the clock. Satellites are close to 20 thousands km. above the Earth. The attraction is there so much weaker satellites clocks ahead of the Earth about 38 millionths of a second a day. To get the accuracy of 10-15 meters, the GPS receiver needs to know the super-accurate time transmission of the satellite signal. Error no greater than 50 nanoseconds.
