There are vast many problems unsolved in considering the SYSTEM of astrology in depth. One of them will be
the definition of sign boundary settled. As the address of the location in a city is nominated by counting the
street number from the map origin of that city located. The place of a planet is counted from the origin of sky or
the equinox of the year observed. In case when we find the place of a planet at 29 degrees 59 seconds in Aries,
the necessary treatment in the formula at the last figure should round off to the nearest whole number.
The sign boundary should have to be studied philosophically before discussing it with the art of treatment in
the mathematical procedures involved. In this age of computerized mathematical calculation, the figures in
the formulas are processed into precision of a second During the middle ages of Europe, people were in rough
to settle the sign boundary philosophically but to erroneously introduce the concept of an orb of aspect into the
place of sign boundary debated.
Such rough and blundered application of an orb of aspect at the ill-suited place in
the sign boundary at the end of zodiac sign Aquarius had been committed a fault discussion in the AQUARIAN Ages
that was falsely advocated into the 2000th year instead of the actual year of 2152 or later. 
Therefore, the problems at the sign boundary are now put back to the starting point of discussion.
Then what should be the phase transit of water through ice. We human could not learn the detail of the phase transit in
water and ice since the beginning of the study of physics in the Grecian age of twenty five hundred years ago explored.
The oldest description in Greek on this particular problem would be described by HERODOTUS in the Fifth Century BC on
the water from thawed ice that is in Greek άγόλϋτον written. Unfortunately, no one describes for the matter of phase
or φάση in Greek. While EIDOS or έίδος in Greek should had to be expected in describing all affairs in three categories
of liquid, solid and vapor classified. Rudolf Clausius of Germany in 1865 has described the concept on ENTROPY. The macro
view on the matters of phase transit either in water and ice, or in water and vapor could be solved by it although the micro view
in the actual phase shift is still left for the further study in new CHAOS physics of 1970s.
In this occasion, we may expect
further development of CHAOS physics in exploring the versatile study of astrology in depth.
