James Prescott Joule's Birth Chart
Sun in Sagittarius · Moon in Gemini
James Prescott Joule was an English physicist. Joule studied the nature of heat and discovered its relationship to mechanical work. This led to the law of conservation of energy, which in turn led to the development of the first law of thermodynamics. The SI unit of energy, the joule (J), is named after him. Wikipedia
Sun in Sagittarius
18°55′Your identity is an arrow: meaning, horizon, the faith that there's always wider ground. It expands through the search for meaning, adventure and trust in life. You need wide horizons, philosophy and constant learning in order to make sense of existence.
Moon in Gemini
6°05′Your emotions ask for words: to name them, tell them, understand them in conversation. You process what you feel through thought and speech. Your emotional security comes from understanding your experiences, voicing them and keeping your mind open and flexible.
Birth time not documented
The Ascendant changes sign every two hours, and no verified birth time is recorded for James Prescott Joule, so this chart doesn't set it. Their planets by sign, however, remain reliable.
Section II · The map
Their natal wheel
The sky on the day they were born. The outer ring is the twelve signs; the lines across the centre, the aspects between planets. Without a birth time, houses and the Ascendant aren't drawn.

Planets and aspects
The exact numbers behind the drawing. Each table expands one layer of the wheel.
James Prescott Joule's placements
We compute the placements for the day of birth. Without the exact time the Ascendant and houses can't be fixed, but each planet's sign is reliable.
| Planet | Sign | Degree |
|---|---|---|
| Sun | Sagittarius | 18°55′ |
| Moon | Gemini | 6°05′ |
| Mercury | Capricorn | 5°40′ |
| Venus | Capricorn ℞ | 11°28′ |
| Mars | Sagittarius | 12°21′ |
| Jupiter | Capricorn | 16°42′ |

Beyond the planets
Three keys beyond the ten classical planets, which astrology reads as axes of the chart. All four angles need your birth time.
The wounded healer: a small icy body between Saturn and Uranus. It marks the wound that, once moved through, teaches.
Not a body but a point of the Moon's orbit. It marks the direction of your growth.
The Black Moon: a mathematical point tied to the untamed and what refuses to submit.
James Prescott Joule's aspects
Each aspect is an angle between two planets; it defines how they speak to each other. Aspects to the Moon are approximate: they depend on the exact birth time.
Elements and modalities
How their energy is split across the four elements and the three modalities.
Section IV · The signature
The signature of their sky
The whole at a glance: how the planets are spread, and the accents that set the overall tone of the chart.
Bucket
A group of planets with a single one opposite: that 'handle' planet becomes the channel of the whole chart.
Their energy concentrates in the element of Fire and the Mutable modality.
Saturn is the most connected planet in their chart: 7 aspects tie it to the rest.
Three or more planets together in Sagittarius: a strongly marked focus of energy in that area.
Three or more planets together in Capricorn: a strongly marked focus of energy in that area.
An opposition with a third planet square to both: the chart's engine of tension and achievement.
