presented to Paradisians. That is why every research in physics is blocked, especially every research about Coriolis force. The main hero discovered it when he was trying to check whether the forces really differ on every floor: all things that would be used to make such an experiment, even such as a spring from his ballpen, have been taken from him by the customs officers and no other things that would make such a simple experiment possible are accessible. Then, he discovers that minutes on clocks in living rooms are not equal in length. Finally, he finds out that Paradise is not a ring-tube space station but a train of buildings lying on the surface of the planet. In addition, Tartar is a planet quite well suitable for settlement, and the group in charge built some buildings and gardens for itself and kept the majority of settlers in the fictional Paradise and made them believe that it was an artificial planet.
