What were Shel Silverstein's early influences?
Shel Silverstein's early influences included his mother, who encouraged his creativity, and his exposure to the work of authors such as Lewis Carroll and Dr. Seuss. He also drew inspiration from his time in the military and his experiences traveling.
Did Galileo galilei win the noble prize?
No, Galileo Galilei did not win the Nobel Prize as it was first awarded in 1901, long after his death in 1642. Galileo Galilei was an Italian astronomer, physicist, and engineer who played a crucial role in the scientific revolution of the 17th century.
Did Galileo galile get his fingers cut off?
No, Galileo Galilei did not have his fingers cut off. However, he did face persecution from the Catholic Church for his support of the heliocentric model of the solar system, which challenged the Church's view at the time.
What happened to Galileo as a result of his support of the geocentric theory?
Nothing but he abandoned the geocentric theory quite early. Later he got in trouble for proclaiming that the heliocentic theory was the absolute truth, when scientific knowledge at that time did not provide enough evidence for the claim. He was put on trial by the Vatican for heresy and in court he was asked to provide proof of his statements.
Previously he had said he had a proof but that the cardinals were too stupid to understand it, but in court he was forced to admit there was no proof and he recanted.
However Galileo's important discovery of moons orbiting Jupiter showed that not everything in the Universe revolves round the Earth, and this was a building brick on which eventully more and more evidence was added until in the 18th century after the theory of gravity came along most people believed that the Sun is at the centre. The discovery of stellar parallax in the 19th century put the finishing touch to the heliocentric theory.
Why was Galileo so interested in parallax?
He was on to a brilliant idea about how parallax can be used to estimate some astronomical distances.
What is a telescope and how did it help Galileo learn more about the solar system?
Telescopes have allowed us to see further than the naked eye would ever allow. With the invention of the telescope by Hans Lipperhey, mankind has discovered new planets, constellations and threats to our planet such as comets or meteors. Telescopes have also been one of the main reasons that man has begun to explore space, we see things out there worth discovering and taking a closer look at.
How did Galileo overcome his problems about his research on space?
He renounced his work. The church forced him to declare that all of his research was false. It was only years later that his work was rediscovered. So he never overcame his problems.
What are the three reasons Galileo provides in his argument against condemning Copernicus book?
No-one condemned Copernicus's book. Galileo was told by the catholic church that he could teach Copernicus's theory as a way of predicting the planets' positions in the sky. But Galileo was forbidden from saying the Sun is actually at the centre as a fact, he was only allowed to present it as a theoretical argument.
The church said that religious teachings could not be changed without sufficient evidence. Galileo however said he knew better and proclaimed the heliocentric principle as a fact. His problem was that he had a habit of ridiculing anyone who disagreed with him and that is what got him into trouble.
Eventually Kepler's model of the planets' orbits, published in 1609, was accepted generally after Newton's theoretical discoveries backed it up, and it has been confirmed by numerous observations and measurements since then.
What were Galileo's most important contributions to humanity?
Galileo is considered to be the founder of the science of physics, and he was the first person to experimentally test hypotheses in physics; he established the equivalence of gravitational and inertial mass (but not by dropping things off the Leaning Tower of Pisa; that is just a myth). His astronomical observations were also revolutionary since he was the first person to use a telescope to examine the night sky and the astronomical objects therein. He was and remains a great inspiration to all the scientists who have come after him.
What planet did the Galileo spacecraft slam into in 2003 after orbiting it for nearly eight years?
After circling the Jovian System for more than 7 years, Galileo had nearly depleted the propellant needed to point its antennae toward earth and adjust its flight path. While still in controllable the spacecraft was placed on a course to crash into Planet Jupiter, a manoeuvre designed to eliminate the risk of Galileo colliding with the moon Europa and contaminating its pristine surface.
When was super-Earth discovered?
Super-Earth was discovered by John Travolta and Olivia Newton John sometime in the 1990s while they were filming the movie Grease! ~Emily Remo
Why was Galileo's tried and sentenced to house arrest by the Catholic Church?
Galileo challenged church teachings by saying that the heliocentric model of the universe was true
The Catholic Church charged him with heresy. Due to his support of the heliocentric or sun centered theory. Which directly opposed the Church accepted theory that the sun and planets revolved around the earth.
Did galileo abolish heaven with his theory of the universe?
No, just the childish notion that "heaven" is a physical place just above the sky.
Why does my 1994 GMC Sierra take long to shift from first to second?
The transmission modulator is likely ruptured. Slide under the truck about even with the rear of the transmission on the passenger side. You should see a vacuum hose attached to a round metal modulator on the trans case. Pull off the hose and if trans fluid comes out it's ruptured.
What was the catholic church position on earth and the sun?
the Earth goes around the Sun....just like everyone else thinks.
This astronomer is credited with opening the door to the era of modern astronomy?
The earliest recorded heliocentric ("Sun-centered") model of the solar system is generally attributed to Aristarchus of Samos in the 3rd century BC although several philosophers and mystics of many traditions and cultures hypothesized this possibility before and after him. The idea itself is counterintuitive and the geocentric ("Earth centered"), or Ptolemaic view was favored by most astronomers until well into the 17th century.
It was Nicolaus Copernicus who first proposed a mathematical model of the solar system with the Sun at the center but his work was not widely known at its publishing and his model was not as accurate at predicting the locations of the planets as the (later proven incorrect) Ptolemaic model.
Galileo Galilei was an astronomer of the Copernican school who made important observations of the phases of Venus which proved conclusively that the Ptolemaic system was incorrect. Coupled with his discovery of moons orbiting Jupiter, the case against a geocentric universe was basically insurmountable.
Johannes Kepler, a contemporary of Galileo, created a mathematical model of a heliocentric solar system which could be used to make predictions of the locations of the planets with a high degree of accuracy that was missing from the Copernican model.
While there is no one father of modern astronomy, Copernicus, Galileo and Kepler are the most often referred to Renaissance astronomers who are responsible for the heliocentric model which represents an incredibly important, fundamental and undeniable shift in the way we all view the universe and our place within it.
In the 8th century, Ja'far al-Sadiq refuted the geocentric model of the universe common at the time, in which the Earth is not moving and the Sun, Moon and the planets are orbiting around it. He was the first to refute Ptolemy's theory of the sun having two movements, one going round the Earth in one year and the other going round the earth in 24 hours causing day and night. Al-Sadiq argued that if the Sun is moving round the Earth for one year, it cannot suddenly change its course and go round the Earth for one day. He suggested that this could be explained with a heliocentric theory in which the Earth rotates on its axis and around the Sun. Al-Sadiq also wrote a theory on how the universe is expanding and contracting. He also stated that every object in the universe is always in motion, including objects which appear to be inanimate.[5]
Al-Sadiq's student, Geber (Jabir ibn Hayyan), asked him the following question on the stars:"How does the movement of the stars keep them from falling?"[5]
Al-Sadiq replied:"Put a stone in a sling and swing it round your head. The stone will stay in the sling so long as you are rotating it. But as soon as you stop the rotation, the stone will fall down on the ground. In the same way the perpetual motion of stars keeps them from falling down."[5]
What did galileos observations confirm?
He made many experiments and observations in the field of physics in general.
Which planet was first seen by Galileo in 1610. He described it as the planet with ears?
Galileo described Saturn as having "ears" after he became the first person to observe it through a telescope. The existence of Saturn was known for thousands of years before Galileo.
What famous experiment did Galileo conduct and what did prove?
Leaning Tower of Pisa,' proves objects fall at same speed and acceleration'
What anomalies did Galileos first astronomic observations reveal?
Although they are not considered "anamolies" now, at the time these observations did not fit into standard ideas about the cosmos:
1) Jupiter has moons.
2) The Milky Way consists of stars.
3) Venus has phases over time.
What was galileo galilei's occupation field of expertise?
Galileo Galilei was an Italian astronomer, physicist, and engineer. He is often referred to as the "father of modern observational astronomy," as his contributions to the field revolutionized our understanding of the universe.
How many moons did Galileo see?
The big one for the Earth, of course, which everybody sees. But Galileo was the first known person to see the four "galilean" moons of Jupiter; Europa, Callisto, Ganymede and Io. There are another 60 or so moons of Jupiter, but they are all much smaller; far too small to be seen in Galileo's early telescope!
