What are midpoints (half sums)
Midpoint (half-sum, English midpoint) is the exact midpoint of the arc between two astrological bodies: (A + B) / 2. The creator of cosmobiology, Reinhold Ebertin and the Hamburg school of astrology, Alfred Witte, proved that when the third planet (C) forms an aspect with the midpoint of the other two, a powerful planetary chord arises: A/B = C. Midpoints work independently of the grid houses and show the hidden mechanisms of psychology and fate.
