The rare conjunction of orbital mechanics, the transit of Venus, was perhaps the most anticipated scientific event of the 18th century. Expeditions set off for the far corners of the Earth, including one by Capt. James Cook who sailed to Tahiti to observe the transit.  He went on to discover the continent of Australia where I have lived for the last four decades.  Explorers like Cook went in hopes of answering one of the most vexing scientific questions of the day: How far away is the Sun?


“This was the big unknown for astronomy 250 years ago,” said Owen Gingerich, an emeritus professor of astronomy and history of science at Harvard. Without that number, much else about the solar system was also uncertain: the size of the Sun, the distance between planets, inter alia. The answer that came out of the worldwide 1769 observations was pretty close at 95 million miles. “Historically speaking, it was the beginning of big international science,” said Dr. Gingerich.


It was only in 1627 that anyone realized Venus transits occurred at all. That year, Johannes Kepler, the mathematician and astronomer, published data about the planetary orbits that predicted that Venus would pass directly between Earth and the Sun in 1631.-Ron Price with thanks to:

What a set of revolutions we’ve


seen since Captain Cook was in


Tahiti and we finally learned the


distance to the Sun among other


bodies in our solar system! What


a story it has been in the last 250


years! We each follow these many


revolutions as suits our tastes and


interests. My particular interest is


in the revolution that took place in


the Shaykhi school of Shi’a Islam


known as the Ithnā‘ashariyyah sect,


the Twelvers as they are called…....



It was a revolution that produced, &


will produce, in time, the eclipse of


all traditional religious and political


orthodoxies in the form of a religion


known as the Baha’i Faith….. I have


been associated with it for 60 years!!


* The term eclipse is derived from an ancient Greek noun, a noun which means "the abandonment", "the downfall", or "the darkening of a heavenly body." This noun is derived from a verb which means "to abandon", "to darken", or "to cease to exist." The prefix of the word eclipse, e, comes from a preposition meaning "out," and from a verb meaning "to be absent".

Hi Ron


You may already know these gorgeous NASA HD images of the transit, but if not, I highly commend them.
