“Early that day the weather turned and the snow was melting into dirty water.” This is the first sentence of Raymond Carver’s “Popular Mechanics.” This sentence gives the reader a hint about something happened in the relation of couple in the story and it is falling apart. Then Carver says‚ “cars slushed by the street outside‚ where it was getting dark. But it was getting dark on the inside too.” Now this sentence makes the picture little clear‚ that there is some darkness in the house due to something

scientists the tools to discover how to enter space. He discovered gravitational force and established the three Universal Laws of Motion. By tying these discoveries to the work Johannes Kepler and his Laws of Planetary motion‚ he established classic mechanics the beginning of modern Physics. This was huge in many ways as he proved definitively the heliocentric model first proposed by Copernicus. He also was the first to propose a set of laws that described the motion of all things in the universe. This

Question: Suppose a meteor impact blows some extremophile bacteria from the Earth into the depths of a gas giant planet called planet X ‚ where they evolve into an intelligent species which practises physics. Do you think their physical theories would be similar to ours‚ and if so in what ways would they be likely to be similar? Your answer will necessarily involve some speculation‚ but make sure it involves some careful argument as well. Theoretical physics is one of many braches of physics that

furthered wave particle duality‚ whereby physical systems (i.e.: photons in this case) can display both wave - like and particle like properties and behaviours‚ a concept used by the creators of quantum mechanics. It was explained mathematically by Einstein‚ utilising work in quantum mechanics‚ and was developed by people like Max Planck. The photoelectric effect was not just an immediate discovery with a definite drawn conclusion. It involved many years of research‚ experimentation and debating

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance

“Only seeing general patterns can give us knowledge. Only seeing particular examples can give us understanding.” To what extent do you agree with these assertions? In 2007‚ approximately 1.58 million scientific research papers were published‚ far more than one could possibly read in a lifetime. However‚ when I visited CERN last year‚ I was told that all of our present understanding of physics could be summarised in a few equations: General Relativity‚ describing gravity; and the Standard Model
