The Rubik's cube has haunted peoples nightmares for decades. When it was first made, it was supposed to have “billions” of combinations though it actually has over 43 quintillion combinations (43,252,003,274,489,856,000 to be exact). Originally created to help students understand geometric concepts and 3D space the first wooden model was made in 1974 by Ernö Rubik and a couple of friends. After some time playing with it, Ernö realized he didn't know how to get it back to its original form. He reportedly
In this investigation I will be finding out how many labels are on an exposed side of a 3x3x3 cube when 27 small cubes are put together to make the large 3x3x3 cube. Method I will first start to count the number of small cubes out of the 27; have no labels, 1 label, 2 labels and 3 labels. Once I have done this I will the do the same for a 4x4x4 cube, 5x5x5 cube and finally a 6x6x6 cube and see if I can find a pattern. When I have found a pattern I will try to work out a formula and

strength of concrete that is subjected to heat treatment with unheated one. Concrete ingredients available locally were obtained for the production of concrete cubes into a dimension of 15x15x15 cm. A total of 12 cubes were casted and then cured at room temperature (28 °C). The cubes were divided into 4 sets. Each set comprised of 3 cubes for each Water-Cement ratio. Two of these sets were cured for 14 and 28 days out of which one set each was heated at a temperature of 200oc for about 4 hours. They
specimen is absorbed as plastic deformation when the test specimen yields. Temperature and strain rate effect the yield behaviour and ductility of the material and hence affect the impact energy. Materials that behave this way usually have body-centred cube crystal structures and where lowering the temperature reduces the materials ductility. 2.4.4 Fracture
peroxide and during the decomposition reaction when oxygen is produced, it would produce foam due to the detergent. Picture 1. The picture shows how catalase breaks down hydrogen peroxide into 2 products oxygen and water. https://www.youtube.com/watch?v=BbYsp1kXuzw The aim of the experiment was to investigate the effect of the increasing temperature on the activity of catalase in the dissociation of hydrogen peroxide. It was hypothesised that the highest rate of production of oxygen would be around

control speed. Energy consumption in a centrifugal fan and pump applications follow the affinity laws. Affinity laws determined that the flow is proportional to speed, pressure is proportional to the square of speed, and horsepower is proportional to the cube of speed. That means if an application only needs 80 percent flow, the fan or pump will run at 80 percent of rated speed and only requires 50 percent of rated power. In other words, reducing speed by 20 percent requires only 50 percent of the power
Rationale This exploration is about the optimization of a water bottle, that is, to find out the volume of water contained in a bottle and the surface area of plastic of the bottle and try to reduce the plastic without affecting the volume. Finally, I will evolve why companies don't just use the bottle design with the most volume of water and the least amount of plastic if they are concerned with the environment and want to save themselves some money. The reason for which I chose this topic is
What is a crystal? Crystals are made up of elements which form amd there molecules form a certain pattern. For example, a volcano happens to erupts and magma flows out to the surface of the earth As the magma runs outward then slowly starts to cool. crystals may develop. This is call crystallization. From this occurring expensive crystal like rubies and diamonds are form, sometimes even emeralds. Crystals can have many different shape from the result of the type of molecules and atoms present
angles of an n-gon is (n-2) 180. Theorem 2-4 Polygon Exterior Angle-Sum Theorem The sum of the measures of the exterior angles of a polygon, one at each vertex, is 360. Theorem 2-5 Two lines parallel to a third are parallel to each other. Theorem 2-6 In a plane, two lines perpendicular to a third line are parallel to each other. Theorem 3-1 A composition of reflections in two parallel lines is a translation. Theorem 3-2 A composition of reflections in two intersecting lines is a rotation. Theorem
Daily gum chewing common, but sales trend down Chewing gum makers have spent past five years publicly expressing their deep concern over steadily declining sales and negative trending consumer patterns in the U.S. and Europe. Sales are growing in emerging markets, mostly in Asia, because of the sheer expansion of these economies and their growing middle class. Global sales are expected to reach $22 billion in 2015 from $20 billion today. In Puerto Rico 19% of consumer ages 12 & up buy gum every
owner of the local tavern, and utilized young Johannes as a pot-boy. In the days of his youth, Kepler was often quite ill for one reason or another, leading him to be quite frail and somewhat saddened. After witnessing the Great Comet of 1577, at age 6, Kepler acquired a fondness for astronomy; seeing the lunar eclipse in 1580 also contributed to this great interest. In addition to his strong interest in all things astronomical, young Johannes was rather good at math. Heinrich and Katharina sent Johannes

scheduling under Federal law is determined “according to [its] effects, medical uses, and potential for abuse” (Claim V). In this classification system, marijuana is a Schedule I drug, grouped with heroin, LSD, hashish, methaqualone, and designer drugs. These are drugs having “unpredictable effects, and [causing] severe psychological or physical dependence, or death” (Claim V). A closer analysis of the DEA's Federal Scheduling system reveals that, according to various studies by physicians
The unique nature of diamond is heavily dependent upon its composition, crystal structure, and mechanical, thermal, and electromagnetic properties.1 Of those dependencies, composition exacts the most influence over the characteristics. Crystal structure is the repeating pattern of diamond’s composition, and each of the properties are the result of molecular interaction which is determined by composition. Therefore, composition is paramount in the determination of the qualities of diamond. Before
Abstract—During a one hundred year period, seven great mathematicians made contributions to our mathematical knowledge and notation that enabled the emergence of calculus. All were men of either the Catholic or opposing Protestant faith. Religious politics served as both an impetus and a hindrance to the men’s mathematical advances. The men were Francois Viéte, Simon Stevin, John Napier, Adriaan van Roomen, Galileo Galilei, René Descartes, and Pierre de Fermat. Index Terms—analytical geometry
