The parabolic flight
Gravity is an ubiquitous physical magnitude on the surface of the Earth. There is no material or device capable of eliminating it. The only way to not feel gravity is in free fall. Some airplanes make a maneuver that consists in describing a parabola like the one that would make an arrow shot by an […]
Gravity, a matter of weight
We will travel to Bremen, in Germany, where there is one of the highest drop towers in the world (ZARM), capable of generating microgravity conditions of almost 10 seconds, and which is used by the European Space Agency (ESA) to test space technology. We will measure the differences of gravity between the level of the […]
