metaphysical study of the origin and nature of the universe. A brief synopsis of Hawking indicates that‚ according to Hawking‚ "there is ’no place for a creator’‚ that God does not exist." In his quantum cosmology‚ he indicates‚ "there would be no singularities at which the laws of science broke down and no edge of space-time at which one would have to appeal to God or some new law to set the boundary conditions for space-time . . . The universe would be completely self-contained and not affected by anything

Enhancement or a Restriction? Christianity plays a huge role in many a parishioner’s life‚ but does the influence of a man in the heavens make a positive impact on the world’s society? I’d argue not. I believe that one of the main problems is the singularity of religion. Often Christianity is believed to be infallible‚ leaving no room for change or movement with the times sometimes leaving religion and those who follow them behind on social opinion. This may not be a problem in some cases as due to

Electric Field and the Movement of Charge Perhaps one of the most useful yet taken-for-granted accomplishments of the recent centuries is the development of electric circuits. The flow of charge through wires allows us to cook our food‚ light our homes‚ air-condition our work and living space‚ entertain us with movies and music and even allows us to drive to work or school safely. In this unit of The Physics Classroom‚ we will explore the reasons for why charge flows through wires of electric circuits

You could define art as vision or as intuition‚ as Benedetto Croce does in his essay "What is Art?" By this definition‚ the works of someone with a beautiful vision would be beautiful‚ and art would be an external manifestation of an internal state. The importance of art is related to the nature of our human built environment‚ and whether we create it to be a comfort or a torment. To understand the place of art and beauty in contemporary culture‚ you need to turn to history. You could define art

PHY 305/601 Classical Mechanics Assignment No. 1 1. Consider a particle of mass m constrained to move on a frictionless cylinder of radius R‚ given by the equation ρ=R in cylindrical polar coordinates (ρ‚ φ‚ z). Besides the force of constraint‚ the only force on the mass is force F=-kr directed toward the originUsing z and φ as generalized coordinates find the Lagrangian L‚ solve Lagrange’s equations and describe the motion. 2. Show that the kinetic energy of any holonomic mechanical system has

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

Project 1: 1. Results for a: ht=500/ spd=0mph —too slow! Satellite crashed into Earth! Results for b: ht=500/ spd=100mph —too slow! Satellite crashed into Earth! Results for c: ht=500/ spd=25000mph —too fast! Satellite left viewing area and took off in space somewhere! I was determined to get a 100%‚ so I played around with the numbers until I found that at 500 miles above the Earth‚ the satellite would have to be launched at 16‚700mph in order to reach a perfect orbit.
