Pelion di persano galileo biography

The man representing the Church's point of view was called 'Simplicio'. Church leaders who liked his earlier books were angry at this one. The Inquisition took action in He was arrested and put on trial. They found him " vehemently suspect of heresy ". They reminded him of the fate of Giordano Brunowho had been burnt at the stake for heresy on topics such as transubstantiation and the Trinity.

Bruno also believed the Earth went round the Sun and stars had planets. The Inquisition forced Galileo to recant say he was wrong under the threat of executionand to withdraw his works from publication. Galileo spent the last ten years of his life under house arrest. Galileo has become synonymous with a warrior for scientific truth. Although he had to retract his writings at his trial, it is widely believed that after the trial he insisted that Earth does move around the sun, saying the famous phrase " Eppur si muove ' — still it moves.

This happened just as Galileo's book Il saggiatore The Assayer was about to be published by the Accademia dei Lincei in and Galileo was quick to dedicate this work to the new Pope. The work described Galileo's new scientific method and contains a famous quote regarding mathematics:- Philosophy is written in this grand book, the universe, which stands continually open to our gaze.

But the book cannot be understood unless one first learns to comprehend the language and read the characters in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures without which it is humanly impossible to understand a single word of it; without these one is wandering in a dark labyrinth.

Galileo, therefore, decided to publish his views believing that he could do so without serious consequences from the Church. However by this stage in his life Galileo's health was poor with frequent bouts of severe illness and so even though he began to write his famous Dialogue in it took him six years to complete the work. Galileo attempted to obtain permission from Rome to publish the Dialogue in but this did not prove easy.

Eventually he received permission from Florence, and not Rome. It takes the form of a dialogue between Salviati, who argues for the Copernican system, and Simplicio who is an Aristotelian philosopher. The climax of the book is an argument by Salviati that the Earth moves which was based on Galileo's theory of the tides. Galileo's theory of the tides was entirely false despite being postulated after Kepler had already put forward the correct explanation.

It was unfortunate, given the remarkable truths the Dialogue supported, that the argument which Galileo thought to give the strongest proof of Copernicus 's theory should be incorrect. Illness prevented him from travelling to Rome until Galileo's accusation at the trial which followed was that he had breached the conditions laid down by the Inquisition in However a different version of this decision was produced at the trial rather than the one Galileo had been given at the time.

The truth of the Copernican theory was not an issue therefore; it was taken as a fact at the trial that this theory was false. This was logical, of course, since the judgement of had declared it totally false. Found guilty, Galileo was condemned to lifelong imprisonment, but the sentence was carried out somewhat sympathetically and it amounted to house arrest rather than a prison sentence.

He was able to live first with the Archbishop of Siena, then later to return to his home in Arcetri, near Florence, but had to spend the rest of his life watched over by officers from the Inquisition. In he suffered a severe blow when his daughter Virginia, Sister Maria Celeste, died. She had been a great support to her father through his illnesses and Galileo was shattered and could not work for many months.

When he did manage to restart work, he began to write Discourses and mathematical demonstrations concerning the two new sciences. After Galileo had completed work on the Discourses it was smuggled out of Italy, and taken to Leyden in Holland where it was published. It was his most rigorous mathematical work which treated problems on impetus, moments, and centres of gravity.

Much of this work went back to the unpublished ideas in De Motu from around and the improvements which he had worked out during - In the Discourses he developed his ideas of the inclined plane writing:- I assume that the speed acquired by the same movable object over different inclinations of the plane are equal whenever the heights of those planes are equal.

He then described an experiment using a pendulum to verify his property of inclined planes and used these ideas to give a theorem on acceleration of bodies in free fall:- The time in which a certain distance is traversed by an object moving under uniform acceleration from rest is equal to the time in which the same distance would be traversed by the same movable object moving at a uniform speed of one half the maximum and final speed of the previous uniformly accelerated motion.

After giving further results of this type he gives his famous result that the distance that a body moves from rest under uniform acceleration is proportional to the square of the time taken. One would expect that Galileo's understanding of the pendulum, which he had since he was a young man, would have led him to design a pendulum clock.

In fact he only seems to have thought of this possibility near the end of his life and around he did design the first pendulum clock. Galileo died in early but the significance of his clock design was certainly realised by his son Vincenzo who tried to make a clock to Galileo's plan, but failed. It was a sad end for so great a man to die condemned of heresy.

His will indicated that he wished to be buried beside his father in the family tomb in the Basilica of Santa Croce but his relatives feared, quite rightly, that this would provoke opposition from the Church. His body was concealed and only placed in a fine tomb in the church in by the civil authorities against the wishes of many in the Church.

On 31 Octoberyears after Galileo's death, Pope John Paul II gave an address on behalf of the Catholic Church in which he admitted that errors had been made by the theological advisors in the case of Galileo. He declared the Galileo case closed, but he did not admit that the Church was wrong to convict Galileo on a charge of heresy because of his belief that the Earth rotates round the sun.

InGalileo constructed his first telescope, an optical system consisting of convex and concave lenses, and began systematic astronomical observations.

This marked the rebirth of the telescope, which had been virtually unknown for nearly twenty years, and became a powerful tool for scientific inquiry. Therefore, Galileo can be considered the inventor of the first telescope. He quickly improved his telescope, and according to his own words, "built an instrument so perfect that objects appeared almost a thousand times larger and more than thirty times closer than when observed with the naked eye".

Galileo turned his telescope towards the sky on the night of January 7, What he saw there — the lunar landscape, mountain ranges and peaks — led him to believe that the Moon resembled the Earth and had mountain systems. This discovery contradicted religious dogma and Aristotle's teachings about the special position of Earth among celestial bodies.

Galileo also discovered four moons of Jupiter, which also contradicted Aristotle's teachings. He established that the Sun rotates on its axis. Based on his observations, Galileo concluded that rotational motion was inherent to all celestial bodies and that the heliocentric system proposed by Copernicus was the only true one. Galileo began to advocate more boldly for Copernican theory.

InGalileo entered the University of Pisa to study medicine. Armed with prodigious intelligence and drive, he soon became fascinated pelion di persano galileo biography many subjects, particularly mathematics and physics. While at Pisa, Galileo was exposed to the Aristotelian view of the world, then the leading scientific authority and the only one sanctioned by the Roman Catholic Church.

At first, Galileo supported this view, like any other intellectual of his time, and was on track to be a university professor. However, due to financial difficulties, Galileo left the university in before earning his degree. Galileo continued to study mathematics after leaving the university, supporting himself with minor teaching positions. During this time he began his two-decade study on objects in motion and published The Little Balancedescribing the hydrostatic principles of weighing small quantities, which brought him some fame.

This gained him a teaching post at the University of Pisa, in While there, Galileo conducted his fabled experiments with falling objects and produced his manuscript Du Motu On Motiona departure from Aristotelian views about motion and falling objects. Galileo developed an arrogance about his work, and his strident criticisms of Aristotle left him isolated among his colleagues.

Inhis contract with the University of Pisa was not renewed. Galileo quickly found a new position at the University of Paduateaching geometry, mechanics and astronomy. The appointment was fortunate, for his father had died inleaving Galileo entrusted with the care of his younger brother. During his year tenure at Padua, he gave entertaining lectures and attracted large crowds of followers, further increasing his fame and his sense of mission.

InGalileo met Marina Gamba, a Venetian woman, who bore him three children out of wedlock: daughters Virginia and Livia, and son Vincenzo. He never married Marina, possibly due to financial worries and possibly fearing his illegitimate children would threaten his social standing. Galileo worried his daughters would never marry well, and when they were older, had them enter a convent.

Maria Celeste remained in contact and supported her father through letters until her death.
