No archaeological research is going on There is no protection of ancient monuments So the islanders use the remains of a once powerful culture to build houses and sea-walls. Unfinished statues on the face of the crater Rano Raraku The distance between the figures is 4 ft 7 ins The men who could execute such perfect work must have possessed ultra-modern tools. The distance of Venus from the earth depends on the distance of its orbit from the earth, and it varies between 26,000,000 and 160,625,000 miles. The Russian sondes do not reach Venus by the shortest route. That sounds paradoxical, but the Russian principle for the flight paths of the Venus sondes is valid for all present-day interplanetary flights. The flight path is calculated according to the minimum quantity of fuel necessary for the transport of the space-craft. If the sonde were launched on the direct course to Venus, it would have to have an initial velocity of 20 miles per second. In that case vast quantities of fuel would be used not only at launching, but also for braking the initial velocity later on. Consequently ballistic experts prefer to calculate flight paths that approximate to the movement of the earth as far as possible. The most favourable route on these premises is ten times as long as the direct route, but it allows a launching velocity of 7-175 miles per second and a far lower consumption of fuel. What is there left that is really Utopian? Preliminary research becomes applied science at such a breathtaking speed that science-fiction writers have a hard job inventing the unimaginable. published a report according to which millions of insects that are dangerous to men, animals and plants as disease c carriers could be killed without the ui use of insecticides, the chemical agents with which dangerous insects and their brood are destroyed at present. As early as 1967 Laven was able to show the efficacy of his research in the Burmese town of Okpo, which was plagued by midges. Within a few months Okpo was freed of its plague. In 1969, Professor Hans Laven, Director of the Institute of Genetics at the University of Mainz, Laven had experimented in the laboratories at Mainz for years. In the process he found out that there is
