Two clocks are hydrogen-based, while the other pair use rubidium. The ESA says the clocks are accurate to within 1. Of the 72 Galileo clocks orbiting the Earth, nine have failed. No single satellite appears to have lost all its clocks, though the BBC noted that one has suffered two clock failures. Only one aboard each spacecraft needs to be operational for Galileo to function as designed. Although one hydrogen clock in orbit had reportedly been restarted, this leaves five more in a failed state. Three of the nine failures occurred on the rubidium clocks.

So then what happens to light when it enters our eyes? It slows down and then what? Does it turn into mass? Are we light beings after all? The Physicist November 19, at 7: The lens and the fluid inside of our eyes allow light to pass through slightly slowed but when light hits the back of our eyes it gets absorbed just like it does when it hits a rock; nothing special.
The scale of the universe is vast. What we can see of the universe is a sphere about 27 billion light years across, and that’s hardly the whole universe. Our observations of the universe are limited by the speed of light; since the universe is about billion years old, we can’t see anything farther.
LiteratureReviewHQ interviewed me about this page, and have a podcast. For example, “Von Daniken’s books about ancient astronauts are worthless because he is a convicted forger and embezzler. Another example is this syllogism, which alludes to Alan Turing’s homosexuality: Turing thinks machines think. Therefore, machines don’t think. Note the equivocation in the use of the word “lies”. A common form is an attack on sincerity. For example, “How can you argue for vegetarianism when you wear leather shoes?
A variation related to Argument By Generalization is to attack a whole class of people. For example, “Evolutionary biology is a sinister tool of the materialistic, atheistic religion of Secular Humanism. You can merely show disrespect, or cut down his stature by saying that he seems to be sweating a lot, or that he has forgotten what he said last week. Sometimes the attack is on the other person’s intelligence.

Seventy Sevens of Years til the coming of the Messiah The Bible’s bold declaration that it is the divine and protected word of God is supported by any number of amazing, seemingly impossible prophecies and their fulfillments. Matthew 24 Another fine example can be found in the book of Daniel Ch. This was the one that alerted Simeon Luke 2: The Ancient Hebrews did not use decades as they were a Greek invention, they used “weeks” of seven years each.

Cosmology is the scientific study of the universe as a unified whole, from its earliest moments through its evolution to its ultimate fate. The currently accepted cosmological model is the big bang. In this picture, the expansion of the universe started in an intense… The cosmological expansion When the universe is viewed in the large, a dramatic new feature, not present on small scales, emerges—namely, the cosmological expansion.
On cosmological scales, galaxies or, at least, clusters of galaxies appear to be racing away from one another with the apparent velocity of recession being linearly proportional to the distance of the object. This relation is known as the Hubble law after its discoverer, the American astronomer Edwin Powell Hubble. Interpreted in the simplest fashion, the Hubble law implies that Strong scientific support for this interpretation of a big bang origin of the universe comes from the detection by radio telescopes of a steady and uniform background of microwave radiation.
The cosmic microwave background is believed to be a ghostly remnant of the fierce light of the primeval fireball reduced by cosmic expansion to a shadow of its former splendour but still pervading every corner of the known universe.

The Galileo Debate In this simulation, students become familiar with the arguments used by different players in the debates about Galileo. For this course, there were five different discussion sections.
Similar to GPS, Galileo is the new European navigation system and will have 24 operational satellites at full capacity. Signal priority systems are installed in traffic networks throughout North America, and they enable equipped transit and emergency vehicles to request green signals through equipped intersections, reducing travel time while increasing efficiency. The EMTRAC system also utilizes dead-reckoning navigation through multiple 3D inertial sensors to maintain accuracy in difficult urban conditions, such as urban canyons, tunnels, and multi-level highways.
According to STC President Brad Cross, integration of the Galileo navigation system immediately increases accuracy, and performance will continue to improve in the coming years. During the test, an EMTRAC-equipped vehicle successfully interpreted detection zones and transmitted priority requests to a simulated intersection utilizing only Galileo satellites.
While high precision is not necessary for many signal priority scenarios, Cross says there are specific situations where it is essential.

Galileo Facts Galileo Galilei was an Italian scientist who helped open the eyes of the world to a new way of thinking about the workings of our solar system and astronomy in general.
Read on for interesting facts, quotes and information about Galileo.
Galileo Sir Galileo Galilei (also known as the “Father of Modern Science”) was an Italian scientist, astronomer, and mathematician of the Renaissance era whose methodical discoveries and principles changed our interpretation of the world around us.
As soon as possible the full book of over pp. The given chapter is of immense importance. It is here translated from a Russian edition as well as from the Spanish. It is a complete material on its own. The translator’s own book on “The Struggle for World Power” also deals with the whole problem of super-power and global enslavement through the masters of both usury-Capitalism and terroristic Communism, which are both the tools of the same forces and serving the same purpose.

Universe is created, according to Kepler On this day in B. Kepler is best known for his theories explaining the motion of planets. Kepler was born on December 27, , in Weil der Stadt, Germany. Copernicus believed that the sun, not the earth, was the center of the solar system, a theory that contradicted the prevailing view of the era that the sun revolved around the earth.
Over the next decade, Kepler learned about the work of Italian physicist and astronomer Galileo Galilei , who had invented a telescope with which he discovered lunar mountains and craters, the largest four satellites of Jupiter and the phases of Venus, among other things. Kepler corresponded with Galileo and eventually obtained a telescope of his own and improved upon the design.

Audiences are good at figuring out which elements of a work are on which side of the Fourth Wall. No explanation is necessary for why our hero can hear a ringing telephone but not the movie’s soundtrack, or why the space ship is menaced by the Negative Space Wedgie , but not by the opening credits drifting by outside the ship: It’s also a wonderful thing to play with, and that is what Medium Awareness does; the characters acknowledge and interact with elements and conventions of the medium that shouldn’t technically “exist” in-universe.
Suddenly the characters can hear the ominous background music or the disembodied narration, they can read the subtitles at the bottom of your screen, and they can tell when it’s almost time for a commercial break. Generally, this awareness is brief; it’s used for a joke or two and then never mentioned again. Used this way, it’s Lampshade Hanging as applied to Paratext.
We are all shaking in our boots — wading boots! We are just some dust speck in the entirety of the universe. Humans always like to think they are the center of the universe, but alas, we are not. Remember the UNited Nations?

Astrology in medieval Islam Astrology was taken up enthusiastically by Islamic scholars following the collapse of Alexandria to the Arabs in the 7th century, and the founding of the Abbasid empire in the 8th century. Zael , whose texts were directly influential upon later European astrologers such as Guido Bonatti in the 13th century, and William Lilly in the 17th century.
Amongst the important names of Arabic astrologers, one of the most influential was Albumasur , whose work Introductorium in Astronomiam later became a popular treatise in medieval Europe. The Arabs greatly increased the knowledge of astronomy, and many of the star names that are commonly known today, such as Aldebaran , Altair , Betelgeuse , Rigel and Vega retain the legacy of their language. They also developed the list of Hellenistic lots to the extent that they became historically known as Arabic parts , for which reason it is often wrongly claimed that the Arabic astrologers invented their use, whereas they are clearly known to have been an important feature of Hellenistic astrology.
During the advance of Islamic science some of the practices of astrology were refuted on theological grounds by astronomers such as Al-Farabi Alpharabius , Ibn al-Haytham Alhazen and Avicenna. Their criticisms argued that the methods of astrologers were conjectural rather than empirical , and conflicted with orthodox religious views of Islamic scholars through the suggestion that the Will of God can be precisely known and predicted in advance.
Avicenna considered that the movement of the planets influenced life on earth in a deterministic way, but argued against the capability of determining the exact influence of the stars. Doctors combined Galenic medicine inherited from the Greek physiologist Galen – AD with studies of the stars.

Indeed, this is what Galileo is credited to have done. In fact, Galileo drew the best from the books of Euclid, Archimedes and other ancient mathematicians,4whose greatness he could fully appreciate. In other words, he pushed himself to engineer new experiments that mimicked and explained what he could directly observe in 1. God had created everything from chaos. Galileo was careful not to mention the Bible in this context but could not avoid involving it implicitly. The First Draft and Later Additions 5 the surrounding world before applying mathematics to their interpretation.
Kepler corresponded with Galileo and eventually obtained a telescope of his own and improved upon the design. In , Kepler published the first two of his three laws of planetary motion, which.
It was the first time it had flown and experienced problems from the start. Problems came from the fact the instruments were designed to operate in zero gravity, but had to be tested in the 1 g on the surface of the Earth. As such, things like the 7. When the technicians tried to integrate the entire bay into the rest of the spacecraft, data streams would not synchronize, and lead investigators of the instruments would want to make last minute checks and changes.
On the Lunar Module, the fuel and oxidizer tanks were enlarged on both the descent and ascent stages and the engine bell on the descent stage was extended. Batteries and solar cells were added for increased electrical power. Although it could be driven by either astronaut, the Commander always drove. Its main objectives were to study the plasma, particle, and magnetic field environment of the Moon and map the lunar gravity field.
Specifically, it measured plasma and energetic particle intensities and vector magnetic fields, and facilitated tracking of the satellite velocity to high precision. A basic requirement was that the satellite acquire fields and particle data everywhere on the orbit around the Moon. The satellite orbited the Moon and returned data from August 4, until January
