Number system

Egypt, Syria, Greece, Sicily and Provence. In 1200 he came back to Pisa and utilized the information he had picked up on his goes to compose Liber Abaci in which he acquainted the Latin-talking world with the decimal number framework.…

Development of place value Place value and the ten-base system are important foundations of later mathematical concepts. The development of these concepts takes years and is built upon pre-number and early number development. Therefore, the development of place value and understanding of the ten-base system needs to be understood in relation to early concepts. Classifying and patterning are elements of pre-number development that need to be developed as part of numeracy. Classifying helps…

The number following the decimal point indicates whether the alloy is a casting (.0) or ingot (.1 or .2). A capital letter prefix indicates a modification to a specific alloy. Example: Alloy - A356.1 the capital A (Axxx.x) indicates a modification of alloy 356.1 the number 3 (A3xx.x) indicates Silicon plus copper and/or magnesium series. The 56 (Ax56.1) identifies the alloy within the 3xx…

Energy Equation, (3) Where u and v are velocity component along the x and y directions of a Cartesian coordinate system respectively, t is the time, p is the pressure, Re (= ρU∞d/μ) is the Reynolds number, Pr (= μCp/k) is the Prandtl number, T is the temperature, d is the diameter of cylinder, k is the thermal conductivity of fluid, Cp is the heat capacity of fluid, ρ is the density of fluid, μ is the dynamic viscosity of fluid…

Truths Observed in Nature Demonstrate a Judeo-Christian God Exists When looking at religious beliefs from generations before us, the Judeo-Christian God, the creator, is referred to as “The essence of goodness, love, justice, compassion, and mercy; the protector of the innocent and the faithful; the enemy of the wicked and the infidel. God is pure spirit with no material substance and neither beginning nor end” (White, pg. 284). These arguments of God’s existence are believed to have not been…

05-1,25 m³/s$. The Pitchback Water Wheel Design is a variation of the overshot design. In addition to the gravitational weight of the water, this turbine rotates also under the push of the water flowing below it. This increases the efficiency of the system on one hand but requires also the construction of a ``Pentrough'' nozzle jetting the water into the wheel\cite{AlternativeEnergy}. \subsection{Hydropower…

organizing elements by atomic numbers and chemical properties into groups and periods. The periodic table was created in order to easily find and classify the different elements that are known. Elements are pure substances composed of just one type of atom that cannot be broken down into anything simpler by ordinary chemical means. Some examples are Oxygen, Carbon, Gold, and Silver. [Source A] An atomic number is the number of protons or electrons in an atom, the number that appears over the…

the strategic placement of indentations maximizes lift while minimizing drag, thus leading to the modern day design of a golf ball. Drag and Lift In order to determine why golf balls have dimples, it is important to first look at the forces in the system as a whole. When a golfer hits a ball with a club, it soars through…

customer?s information based on the phone number that someone uses to call your business. Call tracking can become a vital part of your company as you determine what marketing strategies work best for your company. This technology creates a way to track conversions that originate from non-internet sources, but also as a way to get around holes in analytics data obtained from websites. How It Works Call tracking technology works by creating unique phone numbers for your business based on the…

the list goes on. I had a notebook in the third grade in which I would write numbers from one and beyond. Unfortunately that list was never finished; the fact that one could begin to write numbers from the day they were born to the day they would die and would not even be close to infinity is both scary and fascinating to me. This blew my eight year old mind. It sparked this passion in me to expand my knowledge of numbers, how they work and why they worked. Now I’m engaged in Calculus trying to…
