Classical Mechanics John R. Taylor University of Colorado "Excellent" "Superb" "Immensely readable" "Accessible" "A superb text. The clarity and readability of the book is so much better than anything else on the market, that I confidently predict this book will soon be the most widely used book on the subject in all American universities, and probably Canadian and European universities also. I judge it to be at least ten times better, maybe more, than the other two popular classical mechanics books on the market right now, the book by Fowles, which students say is too terse to understand, and the book by Marion and Thornton, which students say is so wordy and lengthy that they feel quickly lost." -American Journal of Physics, April 2004 "The book is excellent. The core of a truly superb mechanics course is covered in Taylor's text. I, personally, want this book now ." Robert Pompi, State University of New York, Binghamton "Taylor's book is unique among classical mechanics texts. It comprehensively covers the field at the Sophomore/Junior level. At the same time, it is immensely readable, a quality that comparable texts lack." Jonathan Friedman, Amherst College "Many of my students thought that Taylor's

A block and tackle is an arrangement of rope and pulleys that allows you to trade force for distance. In this edition of How Stuff Works we will look at how a block and tackle works, and also examine several other force-multiplying devices! Understanding the Block and Tackle Imagine that you have the arrangement of a 100 pound (45.4 kilogram) weight suspended from a rope, as shown below: In the above figure, if you are going to suspend the weight in the air then you have to apply an upward force of 100 pounds to the rope. If the rope is 100 feet (30.5 meters) long and you want to lift the weight up 100 feet, you have to pull in 100 feet of rope to do it. This is simple and obvious.

50. Lagrange Points Overview of the Lagrange points of the sun-earth-system. Links to a detailed derivation. http://www.physics.montana.edu/faculty/cornish/lagrange.html

The Lagrange Points The Italian-French mathematician Josef Lagrange discovered five special points in the vicinity of two orbiting masses where a third, smaller mass can orbit at a fixed distance from the larger masses. More precisely, the Lagrange Points mark positions where the gravitational pull of the two large masses precisely cancels the centripetal acceleration required to rotate with them. Those with a mathematical flair can follow this link to a derivation of Lagrange's result. Of the five Lagrange points, three are unstable and two are stable. The unstable Lagrange points - labelled L1, L2 and L3 - lie along the line connecting the two large masses. The stable Lagrange points - labelled L4 and L5 - form the apex of two equilateral triangles that have the large masses at their vertices. Lagrange Points of the Earth-Sun system (not drawn to scale!). The L1 point of the Earth-Sun system affords an uninterrupted view of the sun and is currently home to the Solar and Heliospheric Observatory Satellite SOHO . The L2 point of the Earth-Sun system will soon be home to the MAP Satellite and (perhaps) the Next Generation Space Telescope . The L1 and L2 points are unstable on a time scale of approximately 23 days, which requiress satellites parked at these positions to undergo regular course and attitude corrections.

51. Classical Mechanics A short discussion of the development of classical or Newtonian mechanics during the European Enlightenment and its origins in the Aristotelean tradition. This essay is part of http://www.wsu.edu/~dee/GLOSSARY/CLASSMEC.HTM

Ancient Greece Pre-Socratic Philosophy: Pythagoras The Mathematical Principles of Natural Philosophy is that the universe is founded on number and mathematics; this idea, however, was commonplace among the hermeticists (hermeticism is a Western tradition of magic which believes that the universe reflects the mind of god) and dates back to Pythagoras. Ancient Greece Aristotle Pre-Socratic Philosophy: Atomists inertia : every object in motion stays in motion until redirected or stopped by another object; every object remains at rest until moved by another object. No object has the ability to move or stop itself. The universe, then, becomes a vast billiard ball table, in which everything moves because something else has just knocked into it. But that leads to a problem: who moved the first object? How did it get going if no object can move itself? The Greek atomists, who believed that the universe consisted of atoms (in Greek the word atoma means "indivisibles") which created all phenomenon by colliding into and combining with each other, explained this with the concept of "swerve": somewhere at the beginning of time, one atom swerved all by itself and knocked into another and hence the universe came into being. Aristotle , on the other hand, who also based his thought more or less on a mechanistic view of the universe, solved the problem by positing an "Unmoved Mover": somewhere at the beginning of time, an "Unmoved Mover" (which he calls God), was able to set things in motion without having to be moved itself. This idea was appropriated in the Middle Ages by the Scholastics, who, like Aristotle, believed the universe functioned in a rational and mechanistic way and was set in motion and ruled over by a rational and unmoving mover, God. Newton adopts this idea whole-cloth: although the universe is a vast machine of objects moving and colliding into each other, still it requires some original thing that set it all in motion in the first place. That thing, for Newton, was God.

my bits and pieces Home Tensegrity Nonlinear Mappings ... Contact etc. Non linear mappings Mappings as discussed here take the x and y coordinates of a point in the 2D plane and calculate a new set of coordinates according to certain functions. Even simple mapping functions can lead to very complex behaviour when one feeds the output back as new input for the mapping and repeats the process many times (i.e. iterates the mapping). The points either go off to infinity, repeat themselves, trace out lines, or fill certain areas in the plane. See below for instructions on the applet, the Standard Map and the Henon Map This was my very first Java program, written around 1998. It is not perfect, but I learned about multithreading and it does what it's supposed to do NOTE: Java must be enabled in your browser, and settings must allow "Active Content"
