Galileo was the first to use what instrument in his line of work?
Galileo did not invent the telescope. The Italian physicist and mathematician improved on an existing spyglass design to create a more powerful one: a refracting telescope that he then used to study the night sky.
What is Galileo's Diagramma Veritas?
diagram ma Della Verita - the diagram of truth
its an essay by Galileo written for the Illuminati, to tell them about heliocentricity, elliptical orbits, and many other facts considered blasphemous by the Catholic Church. It was written on sedge papyrus, so that any scientist or Illuminatus caught with the Diagramma could simply throw it into water, and Galileo's work would be washed away. There is only one surviving copy, due to the previous method of destruction and Vatican burnings. The only copy is, ironically, kept in the Archives of il Vaticano itself.
Why did catholic church leaders oppose Galileos heliocenric model of the unniverse?
They opposed it because at that time there was no evidence strong enough to abandon the old geocentric theory. Science did not have the evidence until the later theories of gravity and the laws of motion were discovered, and it was then possible to calculate that the Sun is so much more massive than the rest of the solar system that it must be at the centre.
The church leaders knew about the heliocentric theory and asked for the evidence to support it, which was not available at the time, as was proved at Galileo's trial.
What did Aok Sokunkanha do before she becoming famous?
Before becoming famous, Aok Sokunkanha was a singer who performed at weddings, parties, and events in Cambodia. She gained recognition for her talent and eventually rose to fame in the music industry.
well,first they will always choose you,whether it is a game or a team.they will stand near a girl (or boy if gay) they will keep staring at the girl.watch out for these if u r a girl,and do these if u r a boy

What did gallillao discover by using his telescope?
Galileo Galilei discovered that Jupiter has moons (now known as the Galilean moons), observed the phases of Venus, and studied the craters on the Moon. He also confirmed the heliocentric model proposed by Copernicus, which placed the Sun at the center of the solar system.
What does the amount air resistance acting an object depend on?
It depends on the shape of the object.
Why was Galileo the first astronomer to observe the solar system?
Galileo was the first to study the sky with a telescope, record the results, and draw scientific conclusions. Before that, however, there were many people who studied the planets, and in ancient times there was a model explaining how the planets move among the stars, devised by Ptolemy.
What were Copernicus Kepler Galileo Newton pioneers of?
Copernicus kicked it off in 1543, the year he died, with a book called 'De Revolutionibus' in which he described an alternative model for the movements of the planets among the fixed stars. By placing the Sun at the centre he realised that the paths of the planets could be made simpler in their geometry than in the standard Ptolemaic model that had the Earth at the centre and had ruled for 1400 years.
Galileo took this new theory up and promoted it aggressively to the point that he was eventually convicted of heresy by the Catholic church for trying to reinterpret the Bible. That put a wedge between scientists and the church.
Meanwhile Johannes Kepler got hold of some new very accurate measurements of the planets' positions and realised that it could all be very much simplified by assuming elliptical orbits for all the planets. That was published in 1609.
Up to then the models were purely phenomological, in other words they modelled the observed positions, and all three model predicted the planets' positions pretty accurately.
But Newton published the 'Principa' in 1687 and in it he described new theoretical discoveries. He showed by mathematical analysis that a planet moving under the Sun's gravity must follow an elliptical orbit.
After that Kepler's theory gradually became accepted everywhere, and it still is generally accepted.
An atmosphere probe is a spacecraft or instrument designed to study the atmospheric conditions of a planet or moon. It is typically launched into space and sent to the target celestial body to collect data such as temperature, pressure, composition, and other relevant atmospheric properties.
Why did Virginia Gamba change her name to Maria Celeste?
Virginia Gamba was Galileo Galilei's oldest daughter (of three, all born out of wedlock). She and her sisters were sent to a convent and as a nun she adopted the name Maria Celeste (a nod to her father's study of astronomy).
Why was Galileo's view on the sun considered a heresy?
It was considered heretical because he said the Earth revolves round the Sun, in contradiction of the scriptures. The church reckoned it had the last word on questions of reality, but allowed Galileo to teach the heliocentric theory of Copernicus provided he recognised it as only a theory. They would re-examine the question if Galileo could come up with enough evidence, but science did not have enough evidence at that time.
This was proved in the famous trial of Galileo, when he admitted a lack of evidence and recanted. The episode was seized on by the newly created Protestant churches to attack the Catholic church as opposed to progress.
Galielo was wrong during his lifetime, but later scientific discoveries by Newton and others showed that the current model, which uses Kepler's laws and Newton's law of gravity and laws of motion, with the Sun at the centre, is extremely accurate, and this is generally accepted.
Who invented the first closed tube thermometer?
Galileo Galilei is credited with inventing the first closed tube thermometer in the early 17th century. His design consisted of a glass tube filled with liquid and sealed at both ends, using changes in liquid volume to indicate changes in temperature.
Why do you think the catholic church objected to the galileos theories so strongly?
He was charged with heresy, a serious crime in those days, for contradicting the church's belief that the Earth is at the centre of the Universe.
The church said that if there was proof of this idea, they would have to have a rethink. But in court Galileo could produce no proof and he recanted. But later in the 17th century after Galileo's lifetime scientific discoveries led everyone to accept that the Sun is at the centre of the solar system (but not the Universe).
What were Nicolaus Copernicus Galileo Galilei Tycho Brahe Johannes Kepler?
Copernicus 1473-1543 was a Polish priest who reworked the Ptolemaic model of the planets which had the Earth at the centre (geocentric) by instead placing the Sun at the centre (heliocentric).
Both models used circles and epicycles to represent the planets' orbits, which was a reasonably good model for elliptical orbits of low eccentricity.
Predictions from these theories were accepted until the quality of measurements of actual positions eventually showed problems.
Tycho 1546-1601 was a Danish nobleman who set up the best and most accurate measuring systems ever known for observing the positions of stars and planets, with higher accuracy than ever before achieved.
Galileo 1564-1642 adopted the Copernican theory and had a famous battle with the catholic church authorities over whether the heliocentric theory was the absolute truth rather than the geocentric theory as taught by the church at that time.
He was eventually forced to accept the church's teaching for lack of evidence to support the heliocentric theory, but long after his death the heliocentric theory became accepted everywhere.
Kepler 1571-1630 was a mathematical assistant to Tycho, an employee, who used the new measurements to calculate that the planets' orbits are elliptical and that the orbits obey three laws known as Kepler's Laws.
These were later combined mathematically with Newton's law of gravity and the laws of motion, using differential calculus, to show why Kepler's laws were correct. They were also used to find the planet's masses and the Sun's mass.
Who is considered to be the true renaissance man?
Leonardo da Vinci is often considered the quintessential Renaissance man due to his exceptional talents and contributions across multiple fields, including art, science, engineering, and anatomy. His masterpieces, such as "The Last Supper" and "Mona Lisa," showcase his artistic genius, while his notebooks reveal insights into scientific principles and inventions ahead of his time. Da Vinci's insatiable curiosity and interdisciplinary approach exemplify the spirit of the Renaissance, making him a lasting symbol of this era's intellectual and cultural richness.
What are the four largest largest and brightest satellites of Jupiter?
The four satellites are Jupiter's largest moons. They were found by Galileo Galilei.
They are Callisto, Europa, Ganymede and Io.
