Exploring the virtual reality conjecture Brian Whitworth Introduction Computers today simulate entire worlds‚ with their own time‚ space and objects‚ but that our world could be so is normally a topic of science fiction‚ not physics. Yet that the world is illusory has a long history. In Buddhism‚ the world expresses the Universal Mind‚ in Hinduism it is Maya‚ the illusion of "God’s play”‚ and to Plato it was just shadows flickering on a wall1. That the world is digital is also not new‚ as to

Assumptions “There has never been a law of physics that did not demand ‘space’ and ‘time’ for its statement.” John Archibald Wheeler Starting Assumption: Physics today has a large body of experimental observations and mathematical equations that correspond to the experimental observations. Therefore‚ on a superficial level it would appear that we have a good theoretical understanding of nature up to a limit that will be called the frontier of knowledge. However‚ there are many counter intuitive

September 26‚ 2003 CVEN-3313 Theoretical Fluid Mechanics Module#1: 1 1. OBJECTIVE The purpose of this module is to investigate hydrostatic forces on a plane surface under partial and full submersion. 2 2. DESCRIPTION The apparatus shown in Figure 1 will be used. It consists of a quarter circle block attached to a cantilevered arm with a rectangular surface on the other end. The pivot point on the arm corresponds to the center of radius of the block.

TERANO‚ ECE Lesson 5 ROTATIONAL KINEMATICS AND DYNAMICS Uniform Circular Motion – an object moves at a constant speed along a circular path. Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

Since the birth of Physical Review Letters fifty years ago‚ condensed matter physics has seen considerable growth‚ and both the journal and the field have flourished during this period. In this essay‚ I begin with some general comments about condensed matter physics and then give some personal views on the conceptual development of the field and list some highlights. The focus is mostly on theoretical developments. DOI: 10.1103/PhysRevLett.101.250001 PACS numbers: 01.30.−y The transistor

Tug-of-War "Popular Mechanics‚" by Raymond Carver‚ was written in order to make the audience imagine their own details. The descriptions in this story are very blunt‚ the man and woman in the story are nameless with no clue of physical description‚ and there is no mention of what city‚ state‚ or country the story takes place. This allows the reader to picture the surroundings and details of the story in their own way; maybe the reader has heard of or been in similar situations and they can put
