Einstein was a physicist, He resided at many countries namely: Germany, Belgium, Italy, Switzerland, Hungary, and The United States of America. He has obtained citizenship in most of the places he resided. He has won some notable awards including a nobel prize in 1921 for his contribution in the field of physics. He acquired interest in science and mathematics at a very young age, When his father gave him a compass and he observed something made the needles move and he began experimenting on how it works. His father Herman Einstein was an Engineer while his mother was called Pauline Einstein.
Basically their whole life depended on the stars. The Mayans used the stars to tell them when to go to war, harvest crops and other events of life. Astronomy is still in its use today especially because of the invention of the telescope by Galileo. Star spectrum is light coming from a star that is broken down into a rainbow. Spectra can tell us what makes up a star just by analyzing it.
Chapter 14 1. Radio galaxies have sources of unusually strong radio waves emitted on either side of the galaxy and active galaxies are spirals with small, highly luminous cores like Seyfert galaxies, they also have nuclei that are produced by matter plunging into super-massive black holes. 6. By observing the velocity of the stars that orbit the black hole or by the rotational speed of its accretion disk. 10.

Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the observational results and observations being used to confirm theoretical results. Astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena and Amateur astronomers have made and contributed to many important astronomical discoveries. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye. As civilizations developed,
Aristotle was correct about his first argument, but his second one was challenged by a scientist by the name of Ptolemy. Ptolemy elaborated onto Aristotle’s idea of the earth being the in the “center” of the universe second century AD. Next, Hawking discusses the accomplishments of Nicholas Copernicus, a polish priest who contributed to science around 1514. Copernicus’ theory (Copernican theory), stated that the sun was stationary and at the center while the earth and other planets orbited the sun. Nearly a century passed until Copernican
Maxwell began his undergraduate studies at Edinburgh University at age sixteen and entered graduate school at Cambridge University at age nineteen. After graduation, he was a fellow and professor at a variety of colleges in the United Kingdom. Maxwell was inducted as a Fellow of The Royal Society of Edinburgh when he was 25, and promoted to a Fellow of The Royal Society at age 30. After a fruitful career, James Maxwell passed away at the age of 48 of stomach cancer, which was oddly the same cause and timing of his mother’s death when Maxwell was eight years old (Forfar, 1995). Before we start talking about Maxwell’s Equations, let’s look back into history.
Enormously popular French author, the founding father of science fiction with H.G. Wells. Verne's stories, written for adolescents as well as adults, caught the enterprising spirit of the 19th century, its uncritical fascination about scientific progress and inventions. His works were often written in the form of a travel book, which took the readers on a voyage to the moon in From the Earth to the Moon (1865) or to another direction as in A Journey to the Center of the Earth (1864). Many of Verne's ideas have been hailed as prophetic.
There is much evidence behind the Big Bang theory, but it continues to face various challenges. Ultimately, this theory was proved by Arno Penzias and Robert Wilson in 1964. The radio telescope they built detected the background energy which Robert Dicke believed was released by the Big Bang. This theory is also supported by the evidence that the universe has a history – which is not implied by the Steady State hypothesis. Due to today’s advanced technology, “the most powerful modern telescopes can detect objects billions of light-years from Earth”.
The theory of Black Holes and its process is one of the most unique studies of the universe, in that with each discovery made, we un-lock closed doors to knowledge of how the universe was made. In 1798 a French Mathematician Pierre Simon de Laplace came up with the first theory of a Black Hole. He agreed with Newton, that when enough mass is added to a star like the sun, the gravitational pull would become so great that the escape velocity would equal the speed of light. Therefore, the star would blink out and become an invisible star. More than a century later, Einstein, came up with the theory of relativity.
