Bicycle tracks C. Dennis Thron has called attention to the following passage from The Adventure of the Priory School , by Sir Arthur Conan Doyle: `This track, as you perceive, was made by a rider who was going from the direction of the school.' `Or towards it?' `No, no, my dear Watson. The more deeply sunk impression is, of course, the hind wheel, upon which the weight rests. You perceive several places where it has passed across and obliterated the more shallow mark of the front one. It was undoubtedly heading away from the school.' Problems Discuss this passage. Does Holmes know what he's talking about? Try to come up with a method for telling which way a bike has gone by looking at the track it has left. There are all kinds of possibilities here. Which methods do you honestly think will work, and under what conditions? For example, does your method only work if the bike has passed through a patch of wet cement? Would it work for tracks on the beach? Tracks on a patch of dry sidewalk between puddles? Tracks through short, dewy grass? Tracks along a thirty-foot length of brown package-wrapping paper, made by a bike whose tires have been carefully coated with mud, and which has been just ridden long enough before reaching the paper so that the tracks are not appreciably darker at one end of the paper than the other? Try to determine the direction of travel for the idealized bike tracks in Figure Figure 1: Which way did the bicycle go?

124. Finitism In Geometry Approaches to geometry that do not presuppose an infinity of points; by JeanPaul van Bendegem. http://plato.stanford.edu/entries/geometry-finitism/

version history HOW TO CITE THIS ENTRY Stanford Encyclopedia of Philosophy A B C D ... Z This document uses XHTML-1/Unicode to format the display. Older browsers and/or operating systems may not display the formatting correctly. last substantive content change APR Finitism in Geometry In our representations of the world, especially in physics, infinities play a crucial role. The continuum of the real numbers as a representation of time or one-dimensional space is the best known example. However, these same infinities also cause problems. One just has to think about Zeno's paradoxes or the present-day continuation of that discussion, namely, the discussion about supertasks, to see the difficulties. Hence, it is a very tempting idea to investigate whether it is possible to eliminate these infinities and still be able to do physics. This problem reduces first of all to the question of the possibility of a discrete geometry that can approximate classical infinite geometry as closely as possible. If a positive answer can be given to this question, the second question is what could be the possible physical relevance (if any). 1. What is Finitism in Geometry?

History of Ganit (Mathematics) Introduction Ganit (Mathematics) has been considered a very important subject since ancient times. We find very elaborate proof of this in Vedah (which were compiled around 6000 BC). The concept of division, addition et-cetera was used even that time. Concepts of zero and infinite were there. We also find roots of algebra in Vedah. When Indian Beez Ganit reached Arab, they called it Algebra. Algebra was name of the Arabic book that described Indian concepts. This knowledge reached to Europe from there. And thus ancient Indian Beez Ganit is currently referred to as Algebra.

Geometry of Bridge Construction The four kinds of bridges and some combinations A. The beam or truss bridge is, in effect, a pair of girders supporting a deck spanning the gap between two piers. Such a beam has to withstand both compression in its upper parts and tension in its lower parts. Where it passes over supports, other forces come into play. A beam may be a hollow box girder or an open frame or truss. B. An arch bridge can be designed so that no part of it has to withstand tension. Concrete is well suited to arched bridge design. When reinforced concrete is used, a more elegant and sometimes less costly arch can be designed and most concrete arch bridges are reinforced. C. A suspension bridge consists, basically, of a deck suspended from cables slung between high towers. The cables of high tensile steel wire can support an immense weight. The towers are in compression and the deck, often consisting of a long slender truss (used as a hollow beam), is supported at frequent intervals along its length. D.

132. Wilson Stothers' Inversive Geometry And CabriJava Pages Includes Steiner's Porism and the arbelos. http://www.maths.gla.ac.uk/~wilson/cabripages/inversive/inversive0.html

The object of these pages is to introduce inversive geometry Many of the results and ideas are Greek, largely due to Apollonius of Perga We shall approach from the Klein viewpoint, that is to say using a group of transformations of a set of points. To motivate the definitions of the set and its transformations, we begin by looking at a classical greek Theorem (Apollonius's Theorem). Whenever it is useful, we give CabriJava (interactive) illustrations. For example, the CabriJava pane on the right shows three touching red circles. The blue and green circles each touch all of the red circles. By dragging A or B, you can change the red circles, but it is always possible to draw the blue and green circles. Why? That's what inversive geometry is about. You can find an inversive proof here table of contents Apollonian Families The basic properties of inversion The extended plane and i-lines The Equal Angles Theorem ... more on orthogonal i-lines related pages the inversive group the fundamental theorem an inversive invariant appendices Stereographic Projection an alternative approach to the point at infinity and i-lines Very simple cabri macros main geometry page

140. Human Form From Sacred Geometry Discovery of the image of the human form in the patterns of reflective spheres clustered in a structure based on the geometry of the Great Pyramid. http://saturn.vcu.edu/~chenry/

SACRED GEOMETRY New Discoveries Linking The Great Pyramid to the Human Form Professor, Department of Sculpture Virginia Commonwealth University Richmond, Virginia This site is best viewed on Microsoft Internet Explorer 4.0 or higher with screen set to 1024 X 768 pixels, 24 bit ...16 million colors. Set ... View/Text Size ... to Meduim Click on thumbnails to view larger images. For more than twenty years, I have been studying the image generating properties of reflective spheres stacked in 52 degree angle pyramids. The 52 (51.827) degree angle slope of the sides of The Great Pyramid in Cairo, Egypt embodies the Golden Mean which is the ratio that is used in Nature to generate growth patterns in space. Sacred Geometry studies such primal systems which reveal the unity of the cosmos by representing the relationships between numbers geometrically. The Vesica Piscis is one of the most fundamental geometrical forms of this ancient discipline and it reveals the relationship between the The Great Pyramid and the 2 dimensional expansion of a circle of one unit radius R as shown in Figure 1. This relationship is more completely described in The New View Over Atlantis by John Michell published by Thames and Hudson. Figure 1 Vesica Piscis in 2 Dimensions In the early 1970s, I became very interested in the three dimensional representation of this geometry and I visualized this as a three dimensional pyramid inside two intersecting spheres shown in Figure 2.
