Galileo Maritime Academy, Mai Khao

Galileo studied speed and velocity , gravity and free fall , the principle of relativity , inertia , projectile motion and also worked in applied science and technology, describing the properties of pendulums and ” hydrostatic balances”, inventing the thermoscope and various military compasses , and using the telescope for scientific observations of celestial objects.

His contributions to observational astronomy include the telescopic confirmation of the phases of Venus , the observation of the four largest satellites of Jupiter , the observation of Saturn’s rings , and the analysis of sunspots. Galileo’s championing of heliocentrism and Copernicanism met with opposition from within the Catholic Church and from some astronomers. The matter was investigated by the Roman Inquisition in , which concluded that heliocentrism was “foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture”.

He spent the rest of his life under house arrest. Galileo became an accomplished lutenist himself and would have learned early from his father a scepticism for established authority, [17] the value of well-measured or quantified experimentation, an appreciation for a periodic or musical measure of time or rhythm, as well as the results expected from a combination of mathematics and experiment.

Galileo’s Inclined Plane Experiment Main Concept Galileo Galilei is a ball rolling down a ramp would speed up in the exact same way as a falling ball would.

Between and , [1] the Italian scientist Galileo Galilei then professor of mathematics at the University of Pisa is said to have dropped two spheres of different masses from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass, according to a biography by Galileo’s pupil Vincenzo Viviani , composed in and published in According to the story, Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle ‘s theory of gravity which states that objects fall at speed proportional to their mass.

Most historians consider it to have been a thought experiment rather than a physical test. At the time when Viviani asserts that the experiment took place, Galileo had not yet formulated the final version of his law of free fall. He had, however, formulated an earlier version which predicted that bodies of the same material falling through the same medium would fall at the same speed. Galileo set out his ideas about falling bodies, and about projectiles in general, in his book Two New Sciences.

The two sciences were the science of motion, which became the foundation-stone of physics, and the science of materials and construction, an important contribution to engineering. Galileo arrived at his hypothesis by a famous thought experiment outlined in his book On Motion. Drop this system of objects from the top of a tower. If we assume heavier objects do indeed fall faster than lighter ones and conversely, lighter objects fall slower , the string will soon pull taut as the lighter object retards the fall of the heavier object.

But the system considered as a whole is heavier than the heavy object alone, and therefore should fall faster.


The complete system consists of:. The first two IOV satellites were launched on Oct. It includes an initial operational capability phase of 18 operational satellites. The full system will consist of 30 satellites, control centers located in Europe and a network of sensor stations and uplink stations installed around the globe.

The agency’s Kounotori 9 left the ISS on Wednesday carrying waste materials from the station, following the delivery in May of food and water for astronauts, as well as equipment for experiments. And every year, more than rockets blast off and deploy something new into space.

With the two launches ordered from SpaceX Thursday, SES has reserved at least five Falcon 9 missions for launches in the next few years. Crewmembers of the station’s current Expedition 63 are in no immediate danger and will spend the weekend in the orbiting laboratory’s Russian segment, inside the Zvezda service module, NASA officials said in an update today Aug.

The treatise De motu , unpublished until , is an original but unsuccessful attempt to go beyond Aristotelian physics by extending Archimedean hydrostatics to the dynamics of natural motion and reappraising the late-medieval impetus theory to account for violent motion and acceleration.

Europe has formally put its Galileo satellite navigation project on track to provide a functional service during and near-global coverage in with the signing of contracts to build and launch eight more satellites. A second pair will be orbited by Soyuz by the end of this summer.

However from the second half of , a requalified Ariane launcher – known as Ariane 5 ES Galileo – should be equipped with a four-satellite dispenser and be capable of delivering the spacecraft to orbital altitudes of 23,km 12,nm.
