Theater Square Visual

JavaScript Solution to “Theater Square” Problem

Problem 1A as presented on CodeForces: Theatre Square in the capital city of Berland has a rectangular shape with the size n × m meters. On the occasion of the city’s anniversary, a decision was taken to pave the Square with square granite flagstones. Each flagstone is of the size a × a. What is the least number of…

Lens Combinations & The Telephoto Lens

Lens Combination – The Telephoto Lens Introduction: The purpose of this lab is to analyze the properties of a telephoto lens system. This is a system of lenses that provide a long focal length in a relatively short optical system. We will specifically focus on the effective focal lengths and principal planes formed by such…

Measuring The Focal Length of a Converging Lens

Lab 3 – Measuring Focal Length of Converging Lens Introduction: The purpose of this experiment is to determine the focal length of a converging lens using 5 different methods. The methods used are described below: Object at large distance; image nearly in focal plane Bessel’s Method Autocollimation Abbe’s Method Lensmaker’s Formula Part 1: Using “Object at…

Sierpinski Triangle in Fortran 95

I was assigned the task of writing a program (code) in Fortran (.f95) that would plot points according to X and Y and form a figure that resembled the Sierpinksi Triangle. For those of you who are not aware of what the Sierpinksi triangle is,I will give a brief description, but a quick web search…

How To Learn

Brainstorming: The key to understanding something is to know the what, why, how, where, when of a subject. Fast learners do these connections automatically to some extent. You can artificially improve it by using techniques like mind-mapping. Muscle memory: A lot of topics need muscle memory. If you can know multiplication tables, physics constants, some…

Lab 8: Operational Amplifiers

Lab report from the “Art of Electronics” student manual. 8-1 Open Loop Test Circuit Introduction: The purpose of this lab is to become acquainted with the normal output of an operational amplifier (op amp). An op amp is a class of amplifiers that are close to an ideal differential amplifier. Op amps consist of about…

Lab 4: Transistors 1

4-1 Transistor Junctions are Diodes   Introduction: In this lab, we are to check to see if we have a bad transistor. In doing so, we will become familiar with the structure and components of a 2N3904 NPN transistor. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.…
