In his letter to Benedetto Castelli, Galileo argues that using the Bible as evidence against the Copernican system involves three key errors. Firstly, claiming that the Bible shows the Earth to be static and concluding that the Earth therefore does not move is arguing from a false premise; whether the Earth moves or not is a thing which must be demonstrated (or not) through scientific enquiry.
Castelli was involved in the discovery of the phases of Venus: In December 1610, Galileo received a letter from Castelli, asking if the phases of Venus were observable through Galileo's new telescope. [1] Days later, Galileo wrote in a letter to Johannes Kepler saying that he'd observed Venus going through phases, but took complete credit for ...
Galileo replied to Castelli with a long letter laying out his position on the relation between science and Scripture. By 1615, with the controversy over the Earth's motion becoming more widespread and increasingly dangerous, Galileo revised this letter and greatly expanded it; this became the Letter to the Grand Duchess Christina .
Galilei wrote about Castelli's technique to the German Jesuit priest, physicist, and astronomer Christoph Scheiner. [62] Scheiner's helioscope as illustrated in his book Rosa Ursina sive Sol (1626–30) From 1612 to at least 1630, Christoph Scheiner would keep on studying sunspots and constructing new telescopic solar-projection systems.
The Assayer (Italian: Il saggiatore) is a book by Galileo Galilei, published in Rome in October 1623. It is generally considered to be one of the pioneering works of the scientific method, first broaching the idea that the book of nature is to be read with mathematical tools rather than those of scholastic philosophy, as generally held at the time.
The Galileo affair (Italian: il processo a Galileo Galilei) began around 1610, [1] and culminated with the trial and condemnation of Galileo Galilei by the Roman Catholic Inquisition in 1633. Galileo was prosecuted for holding as true the doctrine of heliocentrism , the astronomical model in which the Earth and planets revolve around the Sun at ...
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers.
