Chapter 15 (23): Black Holes a) 15.1: Principle of equivalence (1) The Principle of equivalence: Idea that life in a free falling laboratory and life with no gravity is equivalent. ii) 15.1.2 Gravity or acceleration: (1) In space shuttle it appears as though there is no gravity or force but in reality everything from the shuttle to the pencil inside the shuttle is continuously falling but cause it’s all at the same speed it appears as force less. b) 15. 2 Space-time and gravity (1) Einstein

Hunter O’Rourke 9-8-13 Shooting Dad In Vowell’s opening statement‚ she refers to her house as being “house divided” and what she means is that one of her parents is a Democrat and the other parent is a Republican. On Election Day if you were to drive by her house you would see two different campaign signs in the front yard telling you to vote for two different people because each parent is from a different political party. In paragraph 12‚ Vowell’s father said it was fine that his daughter

one of their weekly Saturday night astronomy shows. At first I was expecting a theatre with an open ceiling and being able to observe and talk about the stars‚ but when I got there I soon realized it was just a dome room. But‚ this wasn’t just any dome room‚ it ended up having a star projector in the middle which illuminated the dark room with stars of how the night sky would look that night. First though‚ we watched a short cartoon film which I couldn’t really apply to the class at all because it

Astronomy is the scientific study of celestial objects like stars‚ comets‚ planets and galaxies. It is derived from Greek words astron and nomos which mean ’star’ and ’law’ respectively. It is related with formation and development of the universe‚ motion of celestial objects‚ evolution‚ physics and chemistry.Since the 20th century‚ the field of astronomy has got divided into two branches: observational and theoretical. Observational astronomy emphasis on acquiring and analyzing the data by using

Tutorial 4 AY2013/14 S2 Stars Brightness‚ Luminosity and Stefan’s Law 1. The Sun has an apparent magnitude of -26.7‚ and Sirius has an apparent magnitude of -1.47. By what factor is the Sun brighter than Sirius in apparent brightness? Note: we define a change of 5 in apparent magnitude to correspond to a factor of 100 in apparent brightness. 2. Sirius is fainter than the Sun in apparent brightness because Sirius lies at a great distance‚ and the apparent brightness of a star is inversely proportional

R*. It represent the 7 new stars forming annually in a year. According to NASA‚ they reported about new stars forming‚ "The team found and confirmed aluminum-26 is found primarily in star forming regions throughout the galaxy and each year our galaxy creates on average about seven new stars." The next value is fp‚ this represents the fraction of those stars per planetary systems. Since there is relationship a 1 to1 ratio of planetary systems between stars and within stars of each habitable planet‚

Space Math Differentiation - "Ch..Ch..Ch..Changes" There are many situations in which differentiation has to be performed on formulae in astrophysics. Many objects such as stars and galaxies display ’differential rotation’ which leads to many interesting and unusual phenomena. The formula describing these phenomena are usually ’differential equations’ that relate changes in one quantity to changes in another. Here are some popular equations used in astrophysics whose differentiation

Pleiades star cluster or “the Seven Sisters” is among the nearest star clusters to Earth and the most discernible to the naked eye. Visible from nearly every location on the planet‚ Pleiades can be seen from the north pole to the southernmost tip of South America. Historically‚ the Pleiades were seen as a group of seven stars‚ Alcyone‚ Atlas‚ Electra‚ Maia‚ Merope‚ Taygeta and Pleione. With modern technology‚ we now know that the Pleiades cluster is actually comprised of several hundred stars. The Pleiades

special equipment for seeing black holes. The tools can see how stars around the black hole act differently than the stars away from the black hole. Black holes were first discovered in 1916 by Karl Schwarzschild. Scientist can not see the black hole because of the strong gravitational pull that takes all the light from the area. They were discovered by how they change stars’(that are around them) orbits.When the black hole and the star are close together‚ it creates a high-energy light that can not

feel that people who are not famous are happier than stars. Fame does not bring happiness because of lost privacy‚ expectations the stars are hailed to‚ and the personal and family time that is lost in a stars life. Privacy becomes an issue because of the paparazzi‚ articles about the stars‚ and when stars go into the public eye. When somebody becomes a star‚ the paparazzi follows them around and continually tries to know the details of the stars life. The paparazzi then writes articles and the articles
