The obliquity can then strongly increase, until the dissipative effects lead it away from the chaotic zone, for a strong value of the obliquity. |
Palmer's obliquity should not be misconstrued as cold blood, his hiddenness as hermeticism. |
In the 9th century the Baghdad astronomers observed that the obliquity of the ecliptic had decreased from the value given in Ptolemy's Almagest. |
Abul Wafa determined accurately the obliquity of the ecliptic in 995 A.D. and calculated the variation in the moon's motion. |
It meets the hypothenuse at an obliquity greater than the limiting angle, and is therefore totally reflected. |
In figure 5, the frequency of precession of the axis of rotation of Venus is traced according to its obliquity. |
