The uncertainty reduction theory was created with intention of giving an explanation to an everyday occurrence when encountering new people. The theory gives reason to something everyday people experience regularly without consciously thinking about it. Psychology had attempted to explain the emotional process of first encounters but never like this. Although a lot of thought and consideration had been put into this‚ there was no way it could consistently cover every aspect it addresses. Diving further

the quantity. The art of estimating these deviations should probably be called uncertainty analysis‚ but for historical reasons is referred to as error analysis. This document contains brief discussions about how errors are reported‚ the kinds of errors that can occur‚ how to estimate random errors‚ and how to carry error estimates into calculated results. We are not‚ and will not be‚ concerned with the “percent error” exercises common in high school‚ where the student is content with calculating

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

5.5 Experimental Setup We here briefly describe the classification algorithms applied‚ the BBC forum dataset [112] used and the performance evaluation measures used to analyze the results. 5.5.1 Classification Algorithms For classification task‚ in this module‚ we used the four classification algorithms of Support Vector Machine‚ Decision Tree‚ Naïve Bayes and Logistic Regression provided in ODM[107]. As discussed earlier that it is used for data mining tasks in a number of existing research works[108-110]

mathematical calculations particularly susceptible to propagating successive errors in downstream operations. Those flows create compounding phenomena‚ known as Propagation of Error‚ with the potential to severely degrade accuracy unless otherwise corrected or compensated. Imagine the profound corollaries of erroneous ship navigation while crossing an ocean‚ missile trajectory on a defense system or medical research for an experimental cancer treatment? In an age where technical accuracy often tethers people

The Physics of Rainbows As we are coming down to the final weeks of winter‚ the days are getting longer‚ and it is slowing starting to warm up. We are all looking forward to springtime‚ with its promises of flowers and rain. Along with this rain brings reminders of rainbows. As Donald Ahrens says in the Meteorology Today magazine‚ “rainbows are one of the most spectacular light shows observed on earth (About).” In fact‚ one of the best ways to view a rainbow at it’s utmost

PHYSICS WORK SHEET - 2 CLASS – IX LESSON : MOTION 1. Analyze the following situation and answer the following questions. A circular track has a circumference of 3140m with AB as one of its diameter. A man riding a scooter moves from A to B along the circular path with a uniform speed of 10 m/s. a) Distance covered by the man b) Displacement of the man c) Time taken by the man in reaching from A to B. 2. A car starting from rest moves with a uniform acceleration of 0.1 m/s2 for 2 minutes. Find the

5 of the biggest unsolved mysteries in physics The mysteries of the universe are as vast and wide as existence itself. Throughout history‚ mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker’s Guide to the Galaxy‚ "I think the problem‚ to be quite honest with you‚ is that you’ve never actually known what the question is." True‚ we have yet to come up with the answers to life‚ the universe
