October 19th‚ 2013 1A Orthographic vs. Isometric By Adam Almassri If you’ve ever seen a drawing where the three dimensions of the object in the drawing are represented in three seperate views‚ where each view shows one of the three planes from the object‚ that means you’ve seen an orthographic drawing. Now if you’ve ever seen a drawing where the 3D drawing shows all three of height‚ width‚ and depth of the object in a single perspective‚ and the viewpoint being at a 45 degree angle

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. The vectors appear to have both direct and inverse relationships with each other. When I move the ball one direction‚ both of the vectors move the

Name: Madison Campbell Partner George Tauber Title: Forces Table Introduction: The purpose of this week’s lab‚ titled “Forces Table”‚ was to look at vectors in two dimensions. The lab was also used to help up understand how to sum up forces and the decomposition. In our experiment‚ we had to estimate a third force that would balance out our other two. This would then make the sum of the forces zero. To calculate our forces we used Newton’s Second Law below: (1) In the above equation‚ the ƩF represents

What holds the complexes together: The set of ligands are held to a metal ion by largely electrostatic forces (although there really is a high degree of covalency). The forces arise from the positive charge on the metal ion and the electric dipoles of the ligands‚ whose negative ends are associated

di Pisa. There he was taught by Dini and Bianchi‚ who quickly influenced Guido to undertake research in geometry. He presented his doctoral thesis Clifford’s Parallelism in Elliptic Spaces in 1900. Most young doctoral students take a few years to make themselves well know in their area. However‚ Guido was lucky for his teacher Bianchi was about to publish an important work on differential geometry. Bianchi discussed the results of Guido’s thesis in his treatise‚ which appeared in 1902. Guido remained

Alexander Grothendieck Alexander Grothendieck is a prominent mathematician who is well known for his theories in algebraic geometry‚ homological algebra and functional analysis. He was born in the capital of Germany‚ Berlin‚ in 1928‚ one year before the Wall Street Crash of 1929. Grothendieck’s parents were Sascha Shapiro and Hanka Grothendieck. Shapiro was a Russian anarchist of Jewish decent‚ prosecuted by the Czar and later by the Bolsheviks. He’d lost his left arm during an attempted prison

occupy a lot of space. Scientists use VSEPR Theory to determine the molecule’s geometry by counting the number of electron domains that surround the central atom. Electron domain can be described as a lone pair‚ single‚ double and triple bond‚ and also even free radical. Lone pairs tend to occupy a lot of space and lower the angle of a bond‚ which gives molecular geometry. Lewis structure help determine the molecular geometries‚ 3D structure‚ and distribution of electrons in order to understand the chemical

Markov Processes 1. Introduction Before we give the definition of a Markov process‚ we will look at an example: Example 1: Suppose that the bus ridership in a city is studied. After examining several years of data‚ it was found that 30% of the people who regularly ride on buses in a given year do not regularly ride the bus in the next year. Also it was found that 20% of the people who do not regularly ride the bus in that year‚ begin to ride the bus regularly the next year. If 5000 people ride the
