Galileo Definition and 47 Threads

Many tutorials that explain the weak principle of equivalence (Galileo, Newton) do not clearly state whether the body is affected by the force of inertia during free fall as a result of the gravitational acceleration of the body. In other words, the question is whether, during the free fall of a...

Quantum mechanics has argued for years that space is not a vacuum. Arguments attempting to brush aside quantum mechanics vacuum theory claiming, it's 'just a quantum mathematical theory' can now put to rest. In this article, laboratory experimentation demonstrates that the Casimir Effect can...

Hi ... air resistance is the reason that objects of different mass fall to Earth at different speeds. In a vacuum all objects fall to Earth at the same rate regardless of mass. OK - I get it but all the experiments that illustrate this tend to rely on tall buildings or massive vacuum chambers...

Hi How can a single man without modern technology succeed in manufacturing such an engineering marvel? Galileo wasn't even an engineer he was a scientist. I'm interested to know that because I have always dreamt to invent and manufacture my own products just like Jimmy neutron but found out...

Aristotle further believed that objects fall at a speed that is proportional to their weight. In other words, if you took a wooden object and a metal object of the same size and dropped them both, the heavier metal object would fall at a proportionally faster speed. link I mean these guys were...

Today, I had a thought experiment where I began to puzzle over inertia of very large masses being dropped. Imagine a scenario where the Moon was suspended 100 m from the surface of the Earth alongside a marble at the same height. Now ignoring air resistance and the gravity exerted by the Moon...

Hello! Imagine you drop a steel ball of weight x from a variable height y. the ball hits a steel ramp on the ground which is at 45 degree's I would like to know how I could work out how far away the ball will land. I have had a good look around for this however the closest thing I can find...

Could anyone offer me a little help with understanding why the principles demonstrated in Galileo's (probably fictional, I know) experiment involving two spheres of the same mass from a tower don't apply in the following situation please? As I understand it, the principle is essentially that...

I'm getting quite stuck on this problem here. Galileo said that Xb = Xa - V*Ta. (This follows from dv = dx/t --> Xa - Xb = t*dv --> the above formula) Thus, it is concluded Xa = Xb + V*Ta, but why? In my thought experiment the objects are moving relative to each other, thus if A is moving away...

Recently I came across an excellent video that brings to life an age-old physics teaching theme... The world’s largest vacuum chamber is NASA’s Space Power Facility in Ohio, pictured below. They remove around 30 tons of air from the chamber in order to test equipment during in-space conditions...

I have a historical question which I'm not finding any reference for. I recall how my former professor of history of science told us that the geocentric model was still taught for about a century in the accademia, long after Galileo's discovery of the phases of Venus and long after the...

I have completed a small project on power analysis using Intel galileo board and arduino IDE. The output is displayed on the serial monitor. Now I want to put the data on dweet.io , as IoT. How should I proceed? I have used ubuntu OS for running arduino. Could anyone give me the step-wise...

I have completed a small project of ac circuit analysis on intel galileo in arduino. I want to make a GUI now. How should I proceed? I know C and a little C++.

Another piece of compelling evidence of the existence of a heliocentric solar system was the discovery of Venus's phases by Galileo Galilei. How was Galileo able to observe these phases with the Sun in the way? Did he simply view only early waxing and late waning phases? I find it questioning...

I am working on a little project with intel galileo gen 2 which involves successive analog voltage readings of a sinusoidal waveform. I am using analogRead() function in Arduino IDE for that purpose. But the on-board ADC is extremely slow.The sampling rate I am getting is terribly small which is...

I am doing a little project with Galileo gen2 about ac circuit analysis in terms of voltage, current, frequency, power and pf. I am using arduino for programming,which is in embedded C. I am facing some problems. Please help me out.. 1. While writing program for frequency, I counted the time lag...

I posted this in the 'programming and CS' section yesterday, but haven't received any reply yet. Maybe some EE people could help.I'm a second year electrical engineering student and I want to work on Intel Galileo Gen 2 for a project. I'm going to attend a workshop on IGG2 and IOT. What do I...

I'm a second year electrical engineering student and I want to work on Intel Galileo Gen 2 for a project. I'm going to attend a workshop on IGG2 and IOT. What do I need to know as prerequisite? I know C programming and a little embedded C..This whole thing is really cool but I'm afraid I...

Homework Statement 2009 it was 400 years ago, Galileo Galilei (1564-1642) for the first time turned his home-built telescope to the sky, and for this reason is celebrated this year the International Year of Astronomy a group of astronomers, optical engineers and teachers developed a Galilean...

One of the many earth-shattering discoveries Galileo made (after lots of rumination, I've concluded he's a tie with Newton as my favorite all time smart guy)...was the fact that a pendulum's period is independent of its excursion. Actually, this is true only for small levels of swing, as what...

This question is from Resnick, Halliday, Krane; Physics 5th edition. This is not actually a homework problem rather a question and so I hope it's not inappropriate to post it here. If m is a light stone and M is a heavy one, according to Aristotle M should fall fall faster than m. Galileo...

Hi, It is often said one of the conditions Pope Urban III granted Galileo permission to write a book expressing his ideas on the solar system was that Galileo would include a paragraph written by the Pope on God's omnipotence. I have been trying unsuccessfully to locate this in a copy of "...

Galileo tried to convince church leaders of the correctness of the Copernican Theory. He had difficulties because the leading thinkers of his day couldn't believe in the rotation of the Earth on its axis. They thought that a spinning Earth would be easily felt and the Earth must be stationary...

Galileo was convicted of heresy and blasphemy for his heliocentric model. However, during the trial, wouldn't Galileo be able to provide experimental evidence and physical proof that would vindicate him?

Hi, This question is about a discussion in the two chief world systems, the second day about p 230 in the modern science library edition (around figures 10 and 11). I haven't found the excerpt online so I hope someone has the book. As an objection to a rotating earth, the claim that any...

Homework Statement Galileo in seeking to discover the laws governing the motion of bodies under the action of their weight, conducted a series of experiments on inclined planes. Choosing as unit of length the distance traveled by the ball the first unit of time, measuring at subsequent time...

I’m going to open a new thread with the following thought because, though it is response to something asserted on another thread, it is actually somewhat off topic. So, it is being asserted on another thread that Galileo, surely one of the great heroes of this particular website, was Italian...

Galileo was first to demonstrate that in the absence of air, all things would truly fall with the same acceleration and 300 years later demonstrated this by the crew of Apollo-15 on the lunar surface (which has gravity & also lacks air) by dropping a hammer and a feather. As moon was seen...

Many stories (including most internet accountings) tell of Galileo using the first telescope to look a the stars in 1609. Some reports suggest it was used earlier. What is the accepted truth re: first use of a telescope to view the stars?

Hello All, I am studying for my introductory astronomy exam and I came about these two question; Galileo discovered a) radioactivity b) some moons of saturn c) 2 moon of Mars d) some moons of Jupiter e) the telescope I know he discovered 4 moons of Jupiter but "some" is a bit...

Hi, I have to pick one of these great scientists to write a middterm item on, so basically I'm curious about what you personally think would be the easiest answer to argue to this question: Which out of Galileo, Kepler or Newton was of the greatest significance in changing the scientific...

Though I believe I have understood some basic ideas, theories and mathematic formulas of SR, I still have a pretty fundamental question: Many textbooks start SR with a light clock consisting of two mirrors and a light blip bouncing in between, claiming that when the light clock moves, the...

I have read that if Galileo had included rotational symmetries in his original relativity theorems then a constant turns up in the mathematics. It is the same constant that Einstein concluded was the velocity of light, but has nothing directly to do with light, it just happens that light travels...

What book of Galileo, in its original Italian, would you recommend an Italian and physics student read? His Dialogue Concerning the Two Chief World Systems (Dialogo sopra i due massimi sistemi del mondo) seems to be only historically relevant whereas his The Assayer (Il Saggiatore) appears more...

Why the Galileo transformations are not correct for inertial systems which are traveling close to the speed of light? What made Lorentz to correct this?

A long time ago, Galileo stated the vertical motion of a falling body is not influenced by its horizontal motion. Is that still true in moderns terms, taking relativity into account? For example, if a particle is fired horizontally at 0.8c, will it hit the ground at the same time as a...

Was Galileo Galilei the first "real" physicist? Before Galileo, I don't think there was physics in the way we think of it today. It seemed that physics was more of a philosophy to the Greeks and Romans, who just came up with theories and didn't try to prove them through experiment. In my...

Hi All ! What is the name of the mechine invented by Galileo to measure the time period of a pendulum?

Is it correct to say that Galileo's relativity is a theory with clocks synchronized by a signal that propagates with infinite speed? sine ira et studio

I'm having trouble with a proble I'm trying to complete. The Problem states: Galileo attempted to measure the speed of light by measuring the time elapsed between his opening a lantern and his seeing the light return from his assistant's lantern. The experiment is illustrated in Figure...

hi I am doing an assignment on Galileo in which i have to disscuss and evaluate this quotation: "One of Galileo's greatest contributions to science was the establishment of the scientific method-that is investigation through experiment" Ive done some stuff on the scientific method but i also...

I am writing an essay on why Galileo's work was important to the development of dynamics, with particular reference to its importance to the development of Newton's Laws of Motion and the Law of Universal Gravition. I've researched some of the stuff that Galileo did: ie. rolling balls down...

Okay, this is not for homework, just curious. I was at a friends this weekend and he had a Galileo temperature gauge. I was trying to figure it out. It is full of glass bubbles that are half full of liquid, some small, some large, with glass weights at the bottom and markers. As the...

this 9-page NASA fact sheet about the circa 1995-2003 Galileo mission at Jupiter is pretty informative http://www.jpl.nasa.gov/news/fact_sheets/galileo0309.pdf also there's this longer document with several chapters here are links to chapters 6 and 8 Chapter 6 has a diagram of...

With all that happened to Galileo on its mission to Jupiter, it becomes difficult not to personify it as The Little Spaceship That Could. For NASA’s Galileo spacecraft kept on going and going... http://physicspost.com/articles.php?articleId=180

On Sunday afternoon, September 21, 2003, the Galileo spacecraft was plunged into Jupiter at over 100,000 miles per hour, thereby ending one of NASA’s most successful planetary missions yet. http://www.space.com/scienceastronomy/galileo_finale_030921.html...
