The Biography of Edwin Hubble

The Biography of Edwin Hubble The astronomer Edwin P. Hubble made one of the most profound discoveries about our universe. He found the cosmos is much larger than the  Milky Way Galaxy. In addition, he discovered that the universe is expanding. This work now helps astronomers measure the universe. For his contributions, Hubble was honored by having his name attached to the orbiting Hubble Space Telescope.   Hubbles Early Life and Education Edwin Powell Hubble was born November 29, 1889, in the small town of Marshfield, Missouri. He moved with his family to Chicago when he was nine years old, and remained there to attend the University of Chicago, where he received a bachelor’s degree in mathematics, astronomy, and philosophy. He then left for Oxford University on a Rhodes Scholarship. Due to the dying wishes of his father, he put his career in the sciences on hold, and instead studied law, literature, and Spanish. Hubble returned to America in 1913 after the death of his father and began teaching high school Spanish, physics, and mathematics at New Albany High School in New Albany, Indiana. However, his interest in astronomy led him to enroll as a graduate student at the Yerkes Observatory in Wisconsin. His work there led him back to the University of Chicago, where he received his Ph.D. in 1917. His thesis was titled Photographic Investigations of Faint Nebulae. It  laid the foundation for the discoveries he later made that changed the face of astronomy. Reaching for the Stars and Galaxies Hubble next enlisted in the Army to serve his country in World War I. He quickly rose to the rank of major and was injured in combat before being discharged in 1919. He went immediately to Mount Wilson Observatory, still in uniform, and began his career as an astronomer. He had access to both the 60-inch and the newly completed 100-inch Hooker reflectors. Hubble effectively spent the remainder of his career there, where he also helped design the 200-inch Hale telescope. Measuring the Size of the Universe Hubble, like other astronomers, was used to seeing strangely shaped fuzzy spiral objects in astronomical images. They all debated what these things were. In the early 1920s, the commonly held wisdom was that they were simply a type of gas cloud called a nebula. These spiral nebulae were popular observation targets, and a lot of effort was spent trying to explain how they could form given the current knowledge of interstellar clouds. The idea that they were whole other galaxies was not even a consideration. At the time it was thought that the entire universe was encapsulated by the Milky Way Galaxy - the extent of which had been precisely measured by Hubble’s rival, Harlow Shapley. To get a better idea of the structure of these objects, Hubble used the 100-inch Hooker reflector to take extremely detailed measurements of several spiral nebulae. As he was observing, he identified several Cepheid variables in these galaxies, including one in the so-called Andromeda Nebula. Cepheids are variable stars whose distances can be precisely determined by measuring their  luminosity and their periods of variability. These variables were first charted and analyzed by astronomer Henrietta Swan Leavitt. She derived the period-luminosity relationship that Hubble used to discover that nebulae he saw could not lie within the Milky Way. This discovery initially met great resistance in the scientific community, including from Harlow Shapley. Ironically, Shapley used Hubble’s methodology to determine the size of the Milky Way. However, the paradigm shift from the Milky Way to other galaxies that Hubble was a tough one for scientists to accept. However, as time passed, the undeniable integrity of Hubble’s work won the day, leading to our current understanding of the universe. The Redshift Problem Hubbles work led him on to a new area of study: the redshift problem. It had plagued astronomers for years. Here is the gist of the problem: spectroscopic measurements of the light emitted from spiral nebulae  showed that it was shifted toward the red end of the electromagnetic spectrum. How could this be?   The explanation turned out to be simple: the galaxies are receding from us at high velocity. The shift of their light toward the red end of the spectrum happens because they are traveling away from us so fast. This shift is called the Doppler shift. Hubble and his colleague Milton Humason used that information to come up with a relationship now known as Hubble’s Law. It states that the farther away a galaxy is from us, the more quickly it is moving away. And, by implication, it also taught that the universe is expanding.   The Nobel Prize Edwin P. Hubble was honored for his work but unfortunately was never considered a candidate for the Nobel Prize. This was not due to a lack of scientific achievement. At the time, astronomy was not recognized as a physics discipline, therefore astronomers were not eligible. Hubble advocated to change this, and at one point even hired a publicity agent to lobby on his behalf. In 1953, the year Hubble died, astronomy was formally declared to be a branch of physics. That paved the way for astronomers to be considered for the prize. Had he not died, it was widely felt that Hubble would have been named that year’s recipient. Since the prize is not awarded posthumously, he did not receive it. Today, of course, astronomy stands on its own as a branch of science that also includes planetary science and space science. Hubble Space Telescope Hubble’s legacy lives on as astronomers continually determine the expansion rate of the universe, and explore distant galaxies. His name adorns the Hubble Space Telescope (HST), which regularly provides spectacular images from the deepest regions of the universe. Fast Facts about Edwin P. Hubble Born  November 29, 1889, Died: September 28, 1953.Married to Grace Burke.A well-known basketball player at the University of Chicago.Originally studied law, but studied astronomy in graduate school.

It is a common observation that employees quit their jobs because they are not satisfied with their performance management system and they believe that the criterion mentioned in the policy against which the appraisal was to be done has not been followed. One of the major causes of employee de-motivation is inconsistencies between policies and their implementation. Many censures have been done worldwide just to study the effectiveness of performance management system. A survey was done by a well renowned consulting firm, Development Dimensions Incorporated, in which it was found that most of the employees communicated overwhelming dissatisfaction with their performance management system (Coens & Jenkins, 2002). When an organization intends to change or improve its’ performance management system it has to take care of two things; firstly the standards against which the performance is measured, and secondly the feedback of appraisal. In order to make feedback more effective, 360 degree feedback method should be used (Denisi & Kluger, 2000). Moreover, standards or key performance indicator should be set in such a way that employee attention is on getting the task done effectively and efficiently, which will result in better employee performance thus having a positive impact on overall organization productivity. Furthermore, employee should be involved in setting their goals while designing the appraisal processes because it will increase its effectiveness (McConkie, 1979). It also gives the employees a sense of involvement. The only way to resolve inconsistencies between policies and its implementation is redefining the policies in such a way that it can practically be

Supply and Demand of ETFs in the market Research Paper

Supply and Demand of ETFs in the market - Research Paper Example The market value of an individual ETF through out a single trading day depends on demand and supply for each and every ETF. They follow Index all through, but they act like Equity. ETFs can also be used to refer to those investment companies which are classified as Unit Investment Trusts (UITs) or open ended companies. Exchange-Traded Fund usually experience changes all through the day as they get to be bought and to be purchased. Exchange-Traded Fund does not have net asset value like mutual funds since it trades like a stock. The leading country in the development of ETF is Canada. It creation has roots in Toronto Stock Exchange with Toronto 35 Index Participation Units. The creation of ETFs starts when a professional investor like an investment bank places a whole stock portfolio with a fund manager where they exchange the basket of securities underlying the Index with the provider of ETF for new ETF shares. That is, the professional investor then receives a given quantity of ETF shares in return for the deposit. These shares can then be traded in the exchange market where they can be sold or bought by professional investors or retail from all parts of Europe. Creation units refer to large blocks of ETF shares which usually range from 100,000 to 200,000 shares per unit. The designated or professional investor or brokers usually break these creation units into individual ETF shares which then trade in the stock exchange. The creation and the issuance of ETFs consist of two markets which include the prima ry market which creates the ETFs and the secondary market which buys or sells the ETF units. The creation of ETFs therefore takes place in the primary market between the authorized participants and the fund. â€Å"In kind† creation on the other hand takes place in authorized participants and more so large financial institution. The ETF shares are created by the deposit of portfolio of stocks into the applicable fund, and this is done in

Similarly, Galen who was a giant in the history of medicine conducted animal experiments to advance the understanding of Anatomy and the Pathology physiology. Ibn Zuhr (Avenzoar) introduced animal testing as an experimental method for testing surgical procedures before applying them to human patients.

Slut shaming is a double standard that is highly n touchable in our society. I see it in the words that come out of my contemporaries, acquaint cues or even my friend's mouths. I see this double standard in an overwhelming amount in our tabloids, blob posts.It is also found in most TV shows, Movies and even song lyrics. One of the earliest definitions Of slut is an untidy woman. It has changed and become a sexual slur targeted towards females. This aspect that there are few words as hurtful as insinuating female promiscuity says a lot about our society. (Definition of slut shaming) Slut shaming also known as slashing, is the idea of shaming and/ or attacking a woman or a girl for being sexual, having one or more sexual partners, acknowledging sex al feelings, and/ or acting on sexual feelings. (From an article in psychology today) Furthermore, it's about the implication that if a woman has sex in which trade action society disapproves of, she should feel guilty and inferior. It is damaging not only to t he girls and women targeted, but to women in general and society as a whole. Terms that imply female romanticist include: tramp, where, sank, hoe, and many more that are not a appropriate for this forum.

Amy Tan s The Joy Luck Club - 1210 Words

In the novel, The Joy Luck Club, Amy Tan tells the story of four Chinese mothers and their American daughters. Throughout the book, Tan talks about the mothers and the life they had in china, the relationship between their mothers, and why they moved to America. She also writes about the daughters who were born and raised in America and their relationship with their mothers. In addition, she talks about the cultural differences between the Chinese mothers and the Chinese-American daughters. Joy Luck Club is one of the best books in showing examples of the differences in Chinese and American culture. Three examples of this that are shown in the book are collectivism versus individualism, humility against self-promotion, and internalizing emotion compared to expressing emotion. As Americans, we value individualism, which is the belief that individual needs are held at a higher importance than the needs of the society or group. In fact, we emphasize individuality and autonomy; encourage being different and having personal goals over collective goals. On the other hand, Chinese value collectivism, which empathizes being collective rather than being individual or having their own identity. This means that they base their decisions on other people and they consider how their decision will affect their family, friends, and colleagues. In addition, they generate decisions for the greater good rather than for personal gain.
