Special relativity

LINEAR WAVE THEORY Linear wave theory can be defined as first-order, small amplitude gravity wave with a sinusoidal shape. This theory has been developed by Airy in 1845. It is easy to apply and give reasonable approximation of wave characteristic for a wide range of wave parameters. However, in some situations, waves are better described by higher order theories or also referred as finite-amplitude wave theories. Although there are limitations to its application, linear theory is still useful…

While many concepts on astronomy of the ancient Greeks are no longer relevant, many of their ideas were used to guide astronomers today in establishing concepts more valid. The ancient Greeks had no clear division of science and philosophy. Neither did they have separate and developed fields such as physics, chemistry, biology, and astronomy. The formerly deficient range of information the ancient Greeks had, allowed an individual to become an expert in several fields whereas nowadays, there is…

and beliefs about the world have changed drastically as I’ve encountered strange scenarios within the world. Of all my beliefs, the one that may be the strangest is one that is similar to what solipsists believe, but I feel it is more in line with relativity. The core of solipsism is that only the self and mind can be to be true while the outside world does not exist. While my belief may seem to be very similar to this, it differs in numerous important aspects. My belief revolves around the…

A spiral galaxy is a certain kind of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence. Spiral galaxies consist of a flat, rotating disc containing stars, gas and dust, and a central concentration of stars known as the bulge.(Sloan) Spiral galaxies resemble spiraling pinwheels, nearly 77% of space consists of spiral galaxies. Though the stars and other visible material contained in such a galaxy lie mostly on a…

Summary Assignment #1 Sunspot Cycle: A Brief History In 1610, shortly after viewing the sun for the first time through a telescope, Galileo became the first European to observe sunspots, which are visibly darker, cooler areas on the sun. A little over 200 years later (in 1843), amateur German astronomer Samuel Heinrich Schwabe discovered that there is a cyclical, eleven, and by extension to a full cycle, twenty-two year pattern to the variation of sunspot counts known as the sunspot cycle. In…

The scientist, Sir Isaac Newton, helped to organize the thinking about forces by formulating three laws. In his book Newton describes his three laws of motion. Newton’s Laws are all around us. To prove this, you will conduct 14 different activities showing everyday examples of these laws. Lab Procedure You will start at a lab station and then move from station to station until you have completed all 14 activities. You will have 3minutes to do the activity at each lab station. Perform the…

3. Tasks In order to get answers to the Mission questions, Euclid will measure the geometry , expansion rate and structure growth in the Universe as a function of redshift. This map, spanning 3/4 of the lifetime of the Universe will complement the single snapshot at z ≈1100 made by WMAP and Planck. By combining the use of Redshift measurements (4.1), Weak gravitational lensing (4.2) and Baryonic Acoustic Oscillations (4.3), both Dark Energy (DE) and Dark Matter(DM) will be investigated in the…

Isaac Newton started working in the optics field in 1666. Then he taught at Cambridge university. He started refracting light to produce a multicolor spectrum, that you can reverse back into a light with another prism. As an outcome in his analysis, he began to speculate color is the outcome of items connecting with previously colored light. instead of items developing color on their own, that is acknowledged as "Newton's theory of color." he also finished the refracting telescope lens will…

Changes affect people every day, and people react to changes in many ways. In Long Day’s Journey into Night, the characters experience many trials and obstacles in their lives that induced a change. In physics, there is the principle known as the Coriolis Effect or Force, which is the effect a rotating object has on the motion of another object. The trials experienced in the lives of the characters are the Coriolis Force in their lives that induced the change in their behavior or lifestyle. The…

The universe today is huge. Scientists and Astronomers are finding new galaxies, planets asteroids, and more. But today, that's not what we are going to talk about. We’re going to talk about galaxies. Have you ever wondered what a galaxy really is? In the early 1900s, astronomers . Astronomers argued about spiral shaped, gas, dust were getting closer to discovering galaxiessome star vast cloud found in the night sky. In 1919, Edwin Hubble, an astronomer found the answers. Hubble used his…
