In the sample of 32 people from the Wikipedia list, 6 had Uranus/Sun aspects closer than 1.4°, double the population average. By my calculation, this result will occur one time in 30 random samples (3.28%) so is highly significant at p=5%. With mean of 2.976 and standard deviation of 1.64, the result of six cases is 1.85 standard deviations more than chance.

This method of population statistical analysis for planetary aspects has not to my knowledge been widely used. A database such as http://cura.free.fr/gauq/11gdcura.html#** with scientists at http://cura.free.fr/gauq/11gdA2.txt can easily be, and has been, linked to planetary data. However, the statistical use I have seen of this data has focused on positions of planets in the sky (Saturn rising effect etc), not on the planets’ angles to each other and to the Sun.

The research I propose here extracts from such a database the difference between all the planetary angles to each other (their aspects) and the angles of a circle divided in 12, with this difference angle defined as the orb of the aspect. In other words, orbs are the difference between the aspect and the closest multiple of 30°. If the aspect between two planets is 92°, orb is 2°, while for an aspect of 149°, orb is 1° (150-1). In the Sun/Uranus case investigated here, the six unusual cases have orb < 1.4°. So 92°, with orb 2°, is looser than any of these six. (Sun and Moon and Pluto are here called planets for ease of reference).

Tarnas claims the combined energy of planetary positions at birth is activated in the human psyche each time a planet transits a main angle to natal planetary positions. This claim is unproven, but the study here provides a path to test it in purely quantitative statistical terms.

The http://cura.free.fr/gauq/11gdcura.html#** database can easily provide a list of all planetary relationships, identifying those in which each group is above or below average. Hence a ‘population map’ for leading scientists, and for the other groups, would emerge.
