Telescopes also indicated mountains and craters on the moon. Future telescopes have discovered geography and weather on the planets in our solar system. Telescopes have also exposed new planets and asteroids. These devices helped us make the first legitimate measurement of the speed of light. Telescopes have also assisted us to comprehend gravity and other vital laws of the physical world.
However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy and the making of calendars, but professional astronomy is nowadays often considered to be synonymous with astrophysics. During the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, which is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena.
We could bring up the case as a sample to demonstrate what we are discussing about. However, adding a question to prove our point is not recommended in academic writing. The subject line information to identify the situation has to be included on the head of the memo. In addition, clarity, correctness, and courtesy are very important and they represent for our efforts. The memo should be clearly written and organized in direct order, beginning with the objective and then systematically and covering the vital bits of information (Rentz, 2008).
Describe two differences between ptolemy’s and Copernicus’s models- What is at the centre of the model and the way in which the planets followed smaller circles in their orbits in ptolemy’s model. 3. Describe two similarities between the two models- The number of planets and the circular orbits are the same. 4. Suggest one way in which our current model of the solar system is different from Copernicus’s- There are more planets because we have more scientific equipment to look out further into space so we discover new things in space.
As a result, the technology that we have in the field is a critical determinant of how much we are able to learn and study in not just the field of physics, but across the board in the physical science fields of astronomy, chemistry, physics, or even the earth sciences. While there have been many advances in recent years that allow for direct measurements within the field of physics, there are still significant obstacles and challenges to making direct observations in many circumstances. Physics is, by definition, the study of energy and matter, and the interaction between them—both of which are impossible to observe with the naked eye. The most common things that the field studies, from energy creation to nanoparticles, and everything involved in the more recent quests for discoveries in subatomic particles and the origins of the universe, all have necessitated creative methods to study things that are so small that no current invention can see them or sense them. That is the first major challenge to making direct measurements in physics—the size of the particle being studied.
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”.

What will happen to the universe in the future? Is there life on other planets? These are just some of the questions to which mankind tries to answer. But it needed all this research? Do we spend too much money for this research To understand life on Earth we must first understand the space.
RAND’s publications do not necessarily reflect the opinions of its research clients and sponsors. is a registered trademark. - iii - PREFACE This paper is the final report of the RAND Internal Research and Development (IR&D) project “Risk Management and Risk Analysis for Complex Projects: Developing a Research Agenda.” The aim of the project was to survey how quantitative risk management and risk analysis methods were applied to the planning and execution of complex projects, particularly those which planned to utilize new and untried technologies. One recent RAND study indicated that such methods, while widely advocated, were not used to plan and manage a critical government satellite development project. This paper recommends several research areas in which RAND could contribute to evaluating the utility of these methods and improving their applicability.
What does Paul Feyerabend’s notion of “Epistemological Anarchism” mean? Evaluate this in relation to his critique of Kuhn’s Paradigms. While Emphasizing the subjective side of science, Kuhn claimed that operating within science means existing within the restrictive confines of the dominant paradigm, which attempts to limit particular questions that can be asked, how these are asked, and how their answers are formulated into viable scientific facts that are accepted by fellow scientists. This paradigm, in turn may actually obstruct the progress of science by nature of being untranslatable to other paradigms and impede rational argument. Kuhn states that a scientist’s switch between one paradigm to the next is similar to a “gestalt switch” where neural programming is required rather than argument and persuasion.
