All truths are easy to understand once they are discovered; the point is to discover them.
Galileo Galilei
Galileo Galilei was an Italian universal scholar. He was a philosopher, mathematician, engineer, physicist, astronomer and cosmologist. Many of his discoveries, especially in mechanics and astronomy, are considered groundbreaking.
In 1589 Galilei was appointed for three years as a university teacher and holder of the chair of mathematics at the University of Pisa. He taught Euclid's elements and elementary astronomy as well as astrology to physicians However, the pay was low; yet he managed to build and sell excellent instruments. He also developed a - still very imprecise - thermometer.
Galilei summarized the results of his mechanical investigations in a manuscript that is today quoted as De motu antiquiora and was only printed in 1890.
The attacks on Aristotle were unkindly received by his Aristotelian colleagues in Pisa. Galileo's employment was not renewed in 1592. His material situation was further aggravated by this, that his father had died in 1591 and now, as the eldest son, he had to take responsibility for his siblings
(one brother and three sisters) and mother.
Galileo was one of the first people to use a telescope to observe the sky. This meant a revolution in astronomy, because until then people had to rely on observations with the naked eye. He discovered that the surface of the moon is rough and uneven.
In the autumn of 1610, the Grand Duke of Tuscany and former pupil of Galileo Cosimo II de' Medici appointed him court mathematician, court philosopher and first professor of mathematics in Pisa without any teaching duties. Galileo was thus given full freedom to devote himself entirely to his research.
In 1633, after more than 20 years of confrontation with the Inquisition of the Roman Catholic Church under the threat of torture and death, he was forced to do so, to renounce his alleged falsehoods. This was because he doubted the doctrine that placed the resting earth at the center of the universe.
From then on he lived on an estate near Florence under house arrest.
On 2 November 1992 Galileo Galilei was formally rehabilitated by the Roman Catholic Church.
He is to receive a statue in the Vatican. In November 2008, the Vatican again distanced itself from the condemnation of Galileo by the papal Inquisition.

Alle Wahrheiten sind leicht zu verstehen, wenn sie einmal entdeckt wurden; es geht darum, sie zu entdecken.
Galileo Galilei
Galileo Galilei war ein italienischer Universalgelehrter. Er war Philosoph, Mathematiker, Ingenieur, Physiker, Astronom und Kosmologe.
Viele seiner Entdeckungen, vor allem in der Mechanik und der Astronomie, gelten als bahnbrechend.
Im Jahr 1589 erhielt Galilei für drei Jahre eine Stelle als Hochschullehrer und Inhaber des Lehrstuhls für Mathematik an der Universität Pisa.
Er unterrichtete Euklids Elemente und elementare Astronomie sowie Astrologie für Mediziner. Die Bezahlung war allerdings gering; dennoch gelang es ihm, vorzügliche Instrumente zu bauen und zu verkaufen. Auch entwickelte er ein – noch sehr ungenau arbeitendes – Thermometer.
Galilei fasste die Ergebnisse seiner mechanischen Untersuchungen in einem Manuskript zusammen, das heute als De motu antiquiora zitiert wird und erst 1890 gedruckt wurde. Darin enthaltene Angriffe auf Aristoteles nahmen seine aristotelisch geprägten Kollegen in Pisa unfreundlich auf. Galileis Anstellung wurde 1592 nicht verlängert. Seine materielle Situation war zusätzlich dadurch verschärft, dass 1591 sein Vater gestorben war und er nun als ältester Sohn auch für seine Geschwister (einen Bruder und drei Schwestern) und Mutter Verantwortung übernehmen musste.
Als einer der ersten Menschen nutzte Galilei ein Fernrohr zur Himmelsbeobachtung. Dies bedeutete eine Revolution in der Astronomie, denn bis dahin waren die Menschen auf Beobachtungen mit dem bloßen Auge angewiesen. Er stellte fest, dass die Oberfläche des Mondes rau und uneben ist.
Im Herbst 1610 ernannte der Großherzog der Toskana und ehemalige Schüler Galileis Cosimo II. de’ Medici ihn zum Hofmathematiker, Hofphilosophen und zum ersten Mathematikprofessor in Pisa ohne jede Lehrverpflichtung. Galilei bekam damit volle Freiheit, sich ganz seinen Forschungen zu widmen.
1633 wurde er, nach über 20-jähriger Auseinandersetzung mit der Inquisition der römisch katholischen Kirche unter Androhung von Folter und Tod dazu gezwungen, seinen angeblichen Irrlehren abzuschwören. Dabei ging es darum, dass er die Lehrmeinung, die die ruhende Erde in den Mittelpunkt des Universums stellte, anzweifelte. Fortand lebte er auf einem Landgut bei Florenz unter Hausarrest.
Am 2. November 1992 wurde Galileo Galilei von der römisch-katholischen Kirche formal rehabilitiert.
Er soll eine Statue im Vatikan erhalten. Im November 2008 distanzierte sich der Vatikan erneut von der Verurteilung Galileis durch die päpstliche Inquisition.
