The contributions of galileo galilei

Contact Author Source Galileo had three big aspects to his professional life. One was his studies on physics, another was the conflicts he had with people in academia and the clergy. This article will examine the astronomical work of his life and perhaps reveal new insights into the man who revolutionized science forever.

The Principle of the Pendulum

Upon hearing about this, Kepler urged Galileo to be more open about it politically and if need be move elsewhere if safety was a concern. Galileo never did move away, but slowly his views trickled out into his work.

He might not have moved because of employment or because of his family of 3 children Taylor Galileo starts to write about astronomy. The purpose of the work may seem confusing to modern readers, for Galileo wrote it in the old style of science, i.

But when we compare this work with Dialogues, which he would write later in his life and refute many of the concepts here, we almost feel like his sole intention was exposing people to these ideas just to show how the modern science technique was superior to crazy undefendable ideas Telescope Not too long after this, a big shift in stellar viewpoint occurred on October 10, A new star seemed to appear in the sky and was even visible at times during the day.

But according to Aristotelian cosmology, the universe was constant and unchanging, yet here was evidence that was contrary to that. Fortunately, the Aristotelians had a convenient explanation: However, when scientists found it to have an immeasurable parallax, they realized that it was far away and not possibly something in the atmosphere.

Galileo was not satisfied with this though. What was the nature of this new star? It had upset the balance of the heavens, and his curiosity took over.

It would lead him to the use of an instrument that would aid in his most famous discoveries and ultimately to his legacy to science That breakthrough was the telescope, something that is attributed to him but was actually developed by Hans Lippershey, a toy maker.

It made use of refraction, or the bending of light rays, versus reflection via mirrors like modern telescopes. By gathering the light with the proper curvature and material for the lenses and by placing them at the appropriate distance from each other, distance objects could be magnified to several times their original size, allowing for study of distant and seemingly small points of light.

After reading up on the lens work of Lipperkey, Galileo grounded and polished his own lenses and even worked at the design of the telescope to improve performance starting in June or July of Those lenses had their flat sides meeting each other.

Not too long after Galileo built this telescope, he began to test it and make further improvements. And finally, in January ofthe telescope was pointed to the sky and the floodgates of knowledge were opened TaylorBrodrick The Starry Messenger Source The Starry Messenger It was through that primitive telescope that he first saw mountains on the moon which went against the conventional thought of the time that the moon was smooth.

And then he turned the telescope to Jupiter on January 7, and noticed small points of light around it. He began to record their positions night by night from February 26 to March 2 and came to a startling conclusion: He could even predict where they would be in the future based on their orbital motions!

Galileo also looked at the Pleiades star cluster and saw over 40 new stars there.

Experiments in Motion

The book is dedicated to the Grand Duke Cosino de Medici of Tuscany and in honor of said gentleman the new satellites of Jupiter are named the Medicean Stars.

Even though Galileo did not suspect they were in fact stars but something more groundbreaking, he wanted more evidence before making such a bold claim TaylorBrodrick Galileo started that book with the moon observations mentioned before. When he saw the dark regions all over its face, they looked like seas and thus that was their name, though in Italian we say mare.

Around them, Galileo could see clear indications of elevation and craters especially when the moon was waxing or waning.

Galileo Galilei Contributions to Astronomy | Space & Astronomy

From there, he goes into detail about some observations on the Milky Way and the stars in it. When he looked at the planets of the solar system, some of them seemed to be a disc in the sky rather than a point of light.

Yet when looking generally at the heavens, he found that stars did not enlarge to the point of being a definite circle, but the number of stars seen did increase. He found that nebulas seem to be clusters of stars, and that the band of the Milky Way was also a collection of stars. After this, he ends the book with a description of his Medicean Stars and how to find them based on his data with 3 being found on January 7, and another one on the 13th.Italian astronomer Galileo Galilei provided a number of scientific insights that laid the foundation for future scientists.

His investigation of the laws of motion and improvements on the. Aug 21,  · Galileo Galilei was born in Pisa in , the first of six children of Vincenzo Galilei, a musician and scholar. In he entered the University of Pisa to study medicine, but was soon.

By his persistent investigation of natural laws he laid foundations for modern experimental science, and by the. Galileo, in full Galileo Galilei, (born February 15, , Pisa [Italy]—died January 8, , Arcetri, near Florence), Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method.

His father was the musician Vincenzo Galilei. Galileo Galilei's mistress Marina Gamba ( – 21 August ?) bore him two daughters, (Maria Celeste (Virginia, –) and Livia (–), both of whom became nuns), and a .

Early life and career In Italian scientist Galileo Galilei, using his own telescope, modeled on an invention recently made in the Netherlands, discovered that the Moon, far from being smooth and utterly unlike Earth, had mountains and craters. By using the lengths of their shadows, Galileo was… In Galileo applied for the chair of mathematics at the University of Bologna but was unsuccessful.
List of Discoveries of Galileo Galilei | Sciencing But Galileo was also responsible for several other major discoveries in the field of physics and motion. While forced to deal with an inquisition by the Church over his work, Galileo forged on, making paradigm-shifting discoveries that redefined the known laws of the universe.
{dialog-heading} NASA Italian astronomer Galileo Galilei provided a number of scientific insights that laid the foundation for future scientists.
Geometric and Military Compass It was all because of his contributions to astronomy and his accomplishments in physics and their connection to astronomy. Newton, a famous scientist who was born after Galileo passed away, considered the ideas of Galileo to illustrate that the laws of movement in heaven and the law of movement on Earth were just the same.

In the 's, Galileo invented the thermometer. In , Galileo perfected the astronomical telescope, improving upon the design of Hans Lippershey (which was imprecise and inverted the image.
