Introduction to Measurements & Error Analysis The Uncertainty of Measurements Some numerical statements are exact: Mary has 3 brothers‚ and 2 + 2 = 4. However‚ all measurements have some degree of uncertainty that may come from a variety of sources. The process of evaluating this uncertainty associated with a measurement result is often called uncertainty analysis or error analysis. The complete statement of a measured value should include an estimate of the level of confidence associated

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

The amount of time we spend communicating is outstanding. There have been multiple studies to find the actual amount of our waking lives spent communicating‚ and the percentage of time we spend in each division of communication. The article‚ "Measurement of Time Spent Communicating‚" is the result of a communication study of employees of a research and development laboratory. The study was based on two techniques: direct observation‚ and questionnaires. How much time do people spend communicating

Academic Note Quantitative measures of performance evaluation of salespersons Abstract Aim here is to understand the evaluation techniques used by the firms and understand the quantitative measures used for evaluation. An overview of the analysis is presented after reading various research papers which have been written on similar lines. One of the most important factors that a sales manager has to look after is the performance evaluation of the salesperson. The methodology adopted to evaluate

Curiosity: What is the effect of temperature of saline on cardiac output? HYPOTHESIS: Cardiac output is higher in a hot saline and low in cold saline temperature parameters. Educated Guess Answer: Phenomenally cardiac output is supposed to rise in hot saline conditions and drastically go down in cold saline conditions. Normalising Data Table 2.1: Cardiac output normalised data of frogs in normal‚ hot and cold saline conditions Normal Hot Cold FROG SV(mV/beat) HR(beat/min) Cardiac output(L/min)

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

we know today Galilee had proven Aristotle’s theory to be fallible because two objects of different masses do fall at the same rate. “Galileo’s measurements indicated that each body increased speed at the same rate‚ no matter its weight. This book is consisted of a lot of theoretical physics‚ which pretty much means is a lot of theories about physics whether it is right or wrong. Stephen Hawking gives a miniscule overview about how the current information was developed. From the universe‚ elementary
