Science historian Antonio Favaro dedicated four decades to the study and contextualization of Galileo’s life and work, eventually producing the monumental book Le Opere di Galileo Galilei ( The Works of Galileo Galilei). But did he say it at all? If not, when and how did the myth about this motto start circulating? We can also be certain that he did not (as legend has it) mutter that phrase in front of the inquisitors.
#Galio and yet it moves trial
His bitterness about the trial the fact that he had been forced to abjure and recant his life’s work the humiliating reality that his book Dialogue Concerning the Two Chief World Systems had been put on the Church’s Index of Prohibited Books and his deep contempt for the inquisitors who judged him continually occupied his mind for all the years following the trial. It was only after the trial, angered by his conviction no doubt, that he was said to have muttered to the inquisitors, “ Eppur si muove”(“And yet it moves)”, as if to say that they may have won this battle, but in the end, truth would win out.īut did Galileo really utter those famous words? There is no doubt that he thought along those lines.

That brings us to “and yet.” As much as Galileo may have hoped to convince the Church that in moving Earth from its anointed position, he was not contradicting Scripture, he did not fully appreciate that Church officials could not accept what they regarded as his impudent invasion into their exclusive province: theology.ĭuring his trial for suspicion of heresy, Galileo chose his words carefully. Although he could not prove it, his astronomical observations and his experiments in mechanics led him to conclude that Earth and the other planets were revolving around the sun. Galileo was convinced that model was wrong. “It moves” was a startling denial of the notion, adopted by the Catholic Church at the time, that Earth was at the center of the universe and therefore stood still. That’s good news especially for those planning to venture to one of the poles.“And yet it moves.” This may be the most famous line attributed to the renowned scientist Galileo Galilei. In addition to higher precision than its competitors, its signal also reaches to parts of the world virtually forgotten by GPS or GLONASS. Galileo started offering its services at the end of 2016.

They are following 3 circular routes, with each road being used by 9 working satellites and one backup. The Galileo system comprises of 30 satellites, spinning around the world at 23 222 km above the ground. The Czech Republic is represented in Galileo by satellite named David, that was launched in 2012. Each child is from a different EU and they have earned this honor by winning an art competition. To promote the system and stress its common values (and also probably to differentiate between the satellite easily), each of the satellites bears a name of one child. The first satellite meant for testing has been sent to space from the Baikonur Cosmodrome in Kazakhstan in 2005.

In fact, the EU passed legislation making sure that all phones sold after 2022 in EU will have the capability support the transfer of caller location information from GNSS (at least Galileo) in the event of 112 emergency calls. Galileo is also intended to be used for search-and-rescue operations. This means that Galileo will be fully available even during exceptional situations – such as a war – which will force the USA or Russia to limit or shut down public use of their systems. Both the American and Russian system has been developed primarily for military use, with private and commercial use being just secondary. So, is Galileo the same as a GPS or GLONASS? Almost, but there is one very important difference. The European Union countries are cooperating to create and maintain Galileo, and the whole effort is coordinated by the European Space Agency and European Commission. In 2018, after 13 years of building it was finally completed, and fully functioning since 2019, it became the most precise satellite system. Why create a new satellite system, when we could be using (and most of the time are using) GPS? The main reason is not to be dependent on American (GPS), Russian (GLONASS) or any other systems.
