Continuum Hypothesis in Fluid Mechanics The macroscopic behavior of fluids makes them appear to be continuous. However‚ when viewed at the microscopic scale fluids cannot be viewed as continuous. The fluid under consideration will have molecules bombarding each other. It is not possible to declare the fluid velocity at a point as there is no guarantee that the fluid molecules are present at that point at a particular instant of time. When we calculate the fluid velocity or density at a point it

An efficient market is a market in which prices can always fully reflect available information. According to Andrei Shleifer‚ Market efficiency is theoretically based on three conditions‚ which are investor rationality‚ independent deviations from rationality and unlimited arbitrage. If three conditions cannot be satisfied‚ the market might be not efficient. Thus‚ investors’ rational behavior leads to stock market efficiency. For instance‚ when a company releases new information‚ for all investors

A BRIEF SAPIR-WHORF HYPOTHESIS SUMMARY… October 16‚ 2010 A reasonable summary of the Sapir-Whorf hypothesis in its tractable form is that different cultures interpret the same world differently and this has an impact on how they both think and construct meaning in language; in fact‚ language shapes or influences thought to some degree. The Sapir-Whorf Hypothesis combines linguistic relativity and linguistic determinism. Adherents of the hypothesis follow these two principles to varying degrees

Dr. Geronimus accredits racial disparities and stressful environments as contributing factors to the premature aging. However‚ there are many other reasons as to why the African American

foundation of Bell’s argument in The Aesthetic Hypothesis is based on a personal experience. More specifically‚ a “personal experience of a peculiar emotion” in which the “objects that provoke this emotion we call works of art.”1 According to Bell‚ this is not an assumption‚ but instead fact. His essay does not argue the validity of aesthetic emotions in relation to art‚ but instead he focuses his work on identifying the common quality that provokes this emotion‚ what he calls Significant Form. Using Bell’s

I will begin by asking 150 people when they were born. Then‚ I will research every single birthday and figure out what phase of the moon occurred on that day. Finally‚ I will group the birthdays in the different phases and count them. I will then have a conclusion and will be able to observe if the different phases really do affect birth rate.

Problem How can you tell pigment separation by using Chromatography? Objective To prepare a chromatogram‚ separate pigments in a leaf and interpret the chromatogram. Hypothesis If I am to put a chromatography paper into a solvent‚ then it would separate the pigments depending on their Rf value. I think the pigments will separate in this order: Chlorophyll A‚ Chlorophyll B‚ Carotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy
