"Science is the belief in the ignorance of experts. " "I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. " "The first principle is that you must not fool yourself - and you are the easiest person to fool.
" "If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives.

Volume VI - Experiments : Electronics Textbook. The Feynman Lectures on Physics Vol. I Ch. 44: The Laws of Thermodynamics. 44–1Heat engines; the first law So far we have been discussing the properties of matter from the atomic point of view, trying to understand roughly what will happen if we suppose that things are made of atoms obeying certain laws.
However, there are a number of relationships among the properties of substances which can be worked out without consideration of the detailed structure of the materials. The determination of the relationships among the various properties of materials, without knowing their internal structure, is the subject of thermodynamics. Historically, thermodynamics was developed before an understanding of the internal structure of matter was achieved. To give an example: we know from the kinetic theory that the pressure of a gas is caused by molecular bombardment, and we know that if we heat a gas, so that the bombardment increases, the pressure must increase. Let us consider another example. Fig. 44–1.The heated rubber band. Fig. 44–2.The rubber band heat engine. FLP Vol. I Table of Contents. The Entire Physics Archive. Lecture 2: Big Picture of Calculus. Highlights of Calculus is a series of short videos that introduces the basics of calculus—how it works and why it is important.
The intended audience is high school students, college students, or anyone who might need help understanding the subject. Incompressible Flow - Water Hammer - Pipes - Fluid Mechanics - Engineering Reference with Worked Examples. Overview Using The Rigid Column Theory the compressibility of the fluid is ignored and it is assumed that pressure changes caused by opening or closing a valve are felt instantaneously through out the pipe.
In effect the water column is a solid column, which can accelerate or decelerated as an entity. Chapter 44: The Laws of Thermodynamics.

Limiting the amount of products you bring into your home will not only cut down on costs at the grocery store but will keep you and your family healthier.
Below is a list of some common uses for seven household products. Add some drops of essentials oils like lavender, rose, or sweet orange to any of them for extra pleasure! Here are a few more tips to help you go green and save money! Cut up old bath towels. Reuse these as rags for cleaning your house rather than paper towels, which are expensive and contribute to 3,000 pounds of waste in landfills each day.When you grocery shop, leave your list at home.

Special processes of an ideal gas. Phasor Diagrams. Phasor Diagrams In AC electrical theory every power source supplies a voltage that is either a sine wave of one particular frequency or can be considered as a sum of sine waves of differing frequencies.
The neat thing about a sine wave such as V(t) = Asin(ωt + δ) is that it can be considered to be directly related to a vector of length A revolving in a circle with angular velocity ω - in fact just the y component of the vector. The phase constant δ is the starting angle at t = 0. In Figure 1, an animated GIF shows this relation [you may need to click on the image for it to animate]. Since a pen and paper drawing cannot be animated so easily, a 2D drawing of a rotating vector shows the vector inscribed in the centre of a circle as indicated in Figure 2 below. When two sine waves are produced on the same display, one wave is often said to be leading or lagging the other. Considering sine waves as vertical components of vectors has more important properties. 5.23sin(ωt + 76.0°) . Step 1. And. How to Understand, Present and Invent Electronic Circuits.
