Therefore if two spheres have the same Reynold’s number, they should both have the same aerodynamic characteristics even if the spheres are of different sizes and/or are flying at different speeds. The boundary layer is a thin layer of air which lies closely to the surface of the body in motion, and within this layer the adverse pressure gradient is crated which causes the separation of flow. When the Reynolds numbers are low, the boundary is smooth and called laminar. Laminar boundary layers usually

Numbers have had a fascinating presence throughout history. There is evidence of the use of numbers dating back at least twenty-thousand years, such as the discovery of the Ishango bone. The Chinese, Mayans, Romans, Babylonians, and Greeks all had numbering systems.They were all unique and they have all played a role in the use of Numbers in their everyday lives. Numbers have also played a significant role in magic and divination.The I-Ching system from the Chinese, the tarot, and numerology are

Good Moring class, today we are going to be learning about how to add with a number line. Raise you hand if you have ever used a number line to add? If not that perfectly acceptable because after today, you will know how! Your I can statement for to is “I can add numbers using a number line.” We will start out with a demonstration of a number line and vocabulary, then we will use our bodies to understand number lines, we will practice and then you all will complete a worksheet independently. Let

Rational Number Report Through the Rational Number Interview I was able to gain insight into Adams mathematical understanding of fractions, decimals and percentages. As a student in year 5, Adam was able to make connections using various mathematical strategies. Adam has an understanding of infinite numbers, for example, when asked how many decimals are there between each rational number (0.1 and 0.11), he answered promptly with “many numbers”. Adam was able to acknowledge that a fraction can be

Numbers and counting systems are used daily by everyone. Numerous civilizations throughout history like Egypt, Babylonian, Maya and Africa developed a unique number system. They were commonly used to communicate numbers in an everyday life. Since then counting has changed. A few of the earlier systems had principles that survived and helped in some way, shape or form to create our current Hindu Arabic numbering system. It has become widespread. Back in 3000 B.C, ancient Egypt was using the number

Baccalaureate Sir Winston Churchill Secondary Introduction In this investigation, I will consider these sets of numbers that are present in a symmetrical pattern. To commence this task, we will have to consider the five rows of numbers shown below. 1 1 1 3/2 1 1 6/4 6/4 1 1 10/7 10/6 10/7 1 1 15/11 15/9 15/9 15/11 1 Figure 1: The given symmetrical pattern These numbers are arranged in a Pascal’s triangle, which is a triangular array of binomial coefficients that was named

Written Names for Numbers: This section is focusing on connecting oral and written names for numbers with base-ten concepts by using groups of tens or hundreds for counting. It is essential to remember that saying and writing numbers are conventions instead of concepts, and students are learning this by being told instead problem-based activities. It is especially important to remember that these conventions or patterns may be different for English Langauage Learners. Two-Digit Number Names: For two-digit

that I learned from Developing Whole-Number Place-Value Concepts is that place value is an important concept for students to learn. This is so because students need to know the meaning of a number, especially when they are older. For example, when students are in 4th grade, they will need to know larger numbers, like 100,000. They will also need to know how to divide and multiple with larger numbers. So if students do not know the place value of these larger numbers, then they will not be able to understand
