Multimedia Graphic Bell Labs: A Hive of Invention But we idealize America’s present culture of innovation too much. In fact‚ our trailblazing digital firms may not be the hothouse environments for creativity we might think. I find myself arriving at these doubts after spending five years looking at the innovative process at Bell Labs‚ the onetime research and development organization of the country’s formerly monopolistic telephone company‚ AT&T. Why study Bell Labs? It offers a number of lessons

Purpose: The purpose of this lab is to identify the presence of cations and anions in four unknown solutions by identifying whether they are copper‚ silver‚ iron‚ or chloride ions which is done by adding sodium hydroxide‚ solid copper‚ silver nitrate‚ and potassium thiocyanate to the solutions and analyzing the chemical reactions. Introduction: Chemical change‚ unlike physical change is the change in the composition of a substance rather than simply its shape‚ size‚ or state (Marie‚ 2015). Signs

Cheese lab Introduction Scientists work to create new and improved versions of cheese-curdling enzymes‚ as well as to improve the yields and qualities of cheeses. Modern-day cheese makers want to produce large amounts of high-quality cheese in the most economical way. Purpose ▪ Determine which curdling agent produces cheese the fastest. ▪ Determine which curdling agent produces the most cheese. ▪ Examine numerical data to support predictions. ▪ Examine variables that can

“Is Starch Permeable in Cells? Abstract This report presents the weights of 3 samples of water with various amounts of solute after the use of osmosis. Three different tests were performed‚ each with a beaker of water containing varying amounts of starch from 30% concentration (12.5 grams of water) to 15% concentration (9.5 grams of water)‚ and then 0% (10.5 grams of water). To start this experiment‚ we put water into a make-shift dialysis tube‚ a type of semi-permeable membrane tubing made

Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate
