Old Grecian people have defined the word astronomy which connotes a portion of whole knowledge 
  of logical study of astrology long acquired. After this definition, the astronomers have worked 
  most hard to explore the mechanism of celestial bodies they observed. 
On the other hand, the 
  astrologers are busy for seeking the fortune telling arts that are mainly technical items on 
  fit-and-fail of prospect guessed. Thus the astrologers have been innocent on the logical study 
  on the reason to what extent and with what mechanism the human on earth have had to suffer 
  the influence of celestial bodies they examined. 
After the era of Grecian logical debates, those era of many series are found; the era of Roma 
  in much of religious atmosphere, the middle dark ages from the fourth through tenth century 
  in much of spiritual atmosphere, the mechanical civilization age in the eighteenth century 
  and the electrical civilization age in the twentieth century followed. During those long period 
  of years, the astronomers have been working to explore the logical research on the structure 
  involved in either the individual heavenly body or the construction of whole scale of the sky 
  with the aid of the law of elliptical orbit of planet developed by Johannes Kepler (1571-1630)

, 
  the law of universal gravitation developed by Isaac Newton (1643-1727) and the general 
  theory of relativity developed by Albert Einstein (1879-1955) respectively applied. The most 
  astrologers, however, were attracted either in the technology of computer electronics on the 
  calculation of charts in the fortune telling arts, or the statistical analysis made on the fit 
  examples of prediction performed by the astrology such as reported by this author in 1975 
  in AFA Bulletin on the aircraft disasters examined. 
On the other hand, the most astrologers 
  have attracted only a little on the logical research in the exploration of elemental items 
  such as the reason why the human suffers from the influence of stars incurred. Astrology has come at first and astronomy has followed next to the astrology in the historical 
  sequence recorded. Partial reason on an unduly charge from the astronomers that entitled 
  the astrology to be a foolish daughter of astronomy will be in the undeveloped attitude of the 
  most of astrologers in the research confronted.  As the most astrologers are interested in an 
  immediate problem in the fortune telling technique, they are not serious on either the reports 
  of Kolisko of Germany and Kollerstrom of the Great Britain for the reaction of metal on earth 
  with the movement of heavenly bodies

 or a proposal 
  of this author placed in the AFA Bulletin Today’s Astrologers May 2001.

 These few reports of 
  logical researches have seldom accepted by public. 
  In the study of astronomy, we can employ the light, gravity, radio waves and X rays of the 
  tools supported by the physical science. In astrology, there is no tool to explore the reason 
  of reaction of the metal on earth with the movement of planets in the sky observed. It has been a durable discussion of people that many records from many places of 
the world during several ten hundred years on the nice fits of prediction made by 
astrology should be the most sufficient evidences. Of course, there will be no reason 
to ask the prediction if we could not expect a nice fit of the art tried. And still we 
need to know the mechanism of fit to improve the quality of fit of prediction that 
had been left in the hands of practitioners too much relied. Any art needs the help 
of a skilled practitioner who will become active on hand the proper knowledge of 
mechanism of art operated.
