Galileo's Observations of the Moon, Jupiter, Venus and the Sun
Feb 24, †∑ He discovered that the sun has sunspots, which appear to be dark in color. Galileo's discoveries about the Moon, Jupiter's moons, Venus, and sunspots supported the idea that the Sun - not the Earth - was the center of the Universe, as was commonly believed at the time. Galileo Galilei was a very famous astronomer, engineer, and physicist. He is popularly known as the father of observational astronomy. His most noteworthy discovery was that the Earth revolves around the sun. However, Galileo also made several other significant discoveries in physics.
Galileo Galilei ó was an Italian astronomer and scientist who launched the scientific revolution and is widely considered the father of modern science. He was a prolific inventor who is credited with several inventions including a hydrostatic balancea military compass and a forerunner of the modern thermometer.
Galileo is the first known person who studied the skies in detail with a telescope. He made numerous significant discoveries in astronomy including the Phases of Venus and the four largest moons of Jupiter. His contributions to science include the Galilean Invariance and discovery of Isochronism in pendulums. Know why Galileo is considered the father of modern science by studying his 10 major accomplishments and their relevance. Based on Archimedes principleweighing precious metals in air and then in water to determine their purity was a common practice among jewelers in Europe.
Inat the age of 22Galileo developed a better method, which he described in a treatise titled La Bilancetta The Little Balance. The amount by which the counterweight had to be moved when weighing in water could then be determined very accurately by counting the number of turns of the wire.
Thus the proportion of metals, like what are two discoveries by galileo to silver, in the object could be read off directly. A thermoscope is a device that shows changes in temperature.
It consists of a tube in which the liquid rises and falls as the temperature changes. The modern thermometer gradually evolved from the thermoscope. Galileo discovered the principle on which the thermoscope was based and went on to invent the device in Changes in temperature of the glass ball exerted vacuum pressure on the water below causing it to rise or fall in the thin vertical pipe.
Between andGalileo invented an improved military compass or sector. It gave gunners a new and safer way of elevating cannons accurately. In addition, it also allowed them to compute the amount of gunpowder needed based on the size and material of the cannonball. As a geometric instrument, the sector facilitated various mathematical calculations, like computation of the area of any polygon or circular sector.
It became the major calculating instrument in angry birds card game how to play from the end of the sixteenth century till the nineteenth century. Galileo is the first known person to study in detail the properties of pendulums. Beginning inhe began his studies of the pendulum which led him to note that the swings of the pendulum always take the same amount of time, independent of the amplitude.
Thus a pendulum is isochronousi. Isochronism is the reason pendulums proved to be so useful for timekeeping. Galileo also found that the period of oscillation of a pendulum is independent of the mass of the boband proportional to the square root of the length of the pendulum. The first practical refracting telescopes appeared in the Netherlands around the year Galileo Galilei heard of the invention and constructed his own version of the instrument, which is now known as a Galilean telescope.
The first known observations of the planetary phases of Venus were done by Galileo with his telescope in late Galileo Galilei was also one of the first Europeans to observe the phenomena of sunspots ; and the first to discover that the moon had craters, mountains and valleysand was not a translucent and perfect sphere as supposed till then. Study of science was also deeply influenced by religious beliefs. In it Galileo famously wrote that mathematics is the language of science and the only means to achieve lasting truth in physics.
The Assayer is considered one of the pioneering works of the scientific method. In his famous work Dialogue Concerning the Two Chief World SystemsGalileo put forward the basic principle of relativity, that the laws of physics are the same in any system moving at a constant velocity. It summarized his work on the two sciences now known as kinematics and strength of materials. It included his law of falling bodieswhich said that the acceleration of falling bodies was constant and independent of mass ; and his studies of parabolic path of projectiles as a combination of two motions, constant speed and uniform acceleration.
Galileo played a key role in the Copernican Revolution by advocating the heliocentric model of the Solar System, which was ultimately established beyond doubt by Isaac Newton. He is considered the greatest scientist of his age who, more than anyone else, launched the scientific revolution through his telescopic discoveries, theories, emphasis on experimentation and mathematical approach to science. His last work, Two New Sciencesis considered his finest and regarded as an influential landmark in the history what city is disneyworld in florida science.
Due to his immense contribution Galileo Galilei has been called the father of modern science by many people including Albert Einstein and Stephen Hawking.

In January he discovered four moons revolving around Jupiter. He also found that the telescope showed many more stars than are visible with the naked eye. These discoveries were earthshaking, and Galileo quickly produced a little book, Sidereus Nuncius (The Sidereal Messenger), in . In Galileo discovered the four biggest moons of Jupiter (now called the Galilean moons) and the rings of Saturn. Did the Roman Catholic Church execute Galileo? For his heresy in claiming that Earth orbits the Sun, Galileo was sentenced to life imprisonment by the Roman Catholic Church in Jan 24, †∑ The Discoveries of Galileo Ė Part 2: Sunspots and Their Movements Last month I wrote in Part 1 about Galileoís discovery that the wandering star, Jupiter, was a planet that had four moons. Recall that my motivation was reading the book Discoveries and Opinions of Galileo published in by Stillman Drake, a Canadian historian and authority on the complete works on Galileo.
Galileo Galilei was an Italian physicist and astronomer whose most famous discovery was that the Earth revolves around the sun. 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.
Shortly after the telescope was invented in the Netherlands, Galileo fashioned his own from makeshift spectacle lenses. He learned how to make increasingly powerful telescopes, which he eventually used to to monitor the solar phases of the planet Venus.
After noticing Venus went through similar phases to the moon, he concluded the sun must be the central point of the solar system, not the Earth as was previously assumed. At just 20 years of age, Galileo was in a grand cathedral and noticed that a lamp swinging overhead took exactly the same period of time for each swing, even as the distance of a swing got progressively shorter. This principle of the pendulum made Galileo famous, and was eventually used to regulate clocks.
The law states that a pendulum will always take the same amount of time to finish a swing because there is always the same amount of kinetic energy in the pendulum -- it is merely transferred from one direction to the other.
This law states that all objects will fall at an equal rate, when accounting for relatively minor differences in aerodynamics and weather conditions. Galileo demonstrated this theory by climbing to the top of the Leaning Tower of Pisa and dropping items of various weight off the side.
All items hit the ground at the same time. Contrary to the conventional wisdom established by Aristotle, the speed of a heavy object's fall was found to not be proportional to its weight. Galileo made several astronomical discoveries that people today simply accept as common sense. He discovered that the surface of the moon is rough and uneven as opposed to smooth as people had thought, and in he discovered four moons revolving around Jupiter.
More important than either of these was his finding that many more stars exist than are visible to the eye, an assertion that came as a shocking surprise to the scientific community at the time. For centuries, natural philosophy, which at that time encapsulated such fields as physics and astronomy, was discussed and theorized from a qualitative standpoint. Galileo didn't just discover specific laws of the universe, he reformed the qualitative standpoint and established mathematics as the language of scientific discovery.
He pioneered the scientific method and ushered in the modern practice of experimentation and calculated laws of nature. His doing so led to the revelations that many of the laws of Greek philosophers such as Plato and Aristotle were incorrect.
