• ZH_2_13 — The zodiac — the band of twelve named segments along the ecliptic — exists in two fundamentally different systems that have diverged over two millennia due to the precession of the equinoxes.
• ZH_2_14 — Iatromathematics (Greek: iatros = healer + mathēmatikos = astrologer/mathematician) was the systematic integration of astrology with medical diagnosis and treatment — a dominant medical…
• ZH_2_15 — The measurement and definition of time is humanity's oldest astronomical enterprise — and one that has undergone a radical transformation from celestial observation to atomic precision.
