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.
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.
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 ...
In 1612 Galileo formally set out his views on this topic in his Discourse on Floating Bodies [note 7] and Delle Colombe swiftly replied with Discorso Apologetico [note 8] Galileo did not reply immediately, and indeed when his reply was published, it was over the name of his friend Benedetto Castelli. Galileo may have felt no useful purpose was ...
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.
Parts of the video highlight plumes of smoke rising into the air, as the hot lava makes contact with snow and vegetation. Volcanic activity of Mt. Etna was also linked to earthquakes in the vicinity.
San Francisco Federal Reserve President Mary Daly speaks with reporters after a speech at the Commonwealth Club in San Franciso, California, U.S., March 26, 2019.
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 .
