A parabola is defined to be the set of points P in the plane whose distances from a fixed point F are equal to their distances from a fixed line d. We obtain a parabola in standard form if

1. the focus F lies on the x-axis, and has coordinates (a, 0), where a > 0;

2. the directrix d is the line with equation xÂ =Â âˆ’a.

Thus the origin lies on t

The London equations relate the magnetic field in a superconductor to the superconducting current density, and we derived the dependence of field on position by eliminating the current density. However, if we eliminate the magnetic field instead, we can derive the following equation for the current density:

Space Station Live: Designing an Exercise Program for Space
NASA Public Affairs Officer Amiko Kauderer conducts an interview with Mark Guilliams, Astronaut Strength, Conditioning and Rehabilitation Specialist. Guilliams worked with Hopkins to design an inflight exercise regimen during his mission on board the International Space Station. Hopkins preferred a more intense exercise program with less rest and multiple workouts and worked with Guilliams during preflight training. Watch a video showing Hopkins exercising in space using the Advanced Resistive

Sophisticated methods have been developed to analyse scattering in three-dimensions. The complexity of these methods makes them unsuitable for inclusion in this unit but it is appropriate to say something about the basic quantities involved.

In three dimensions, we are obliged to think in terms of scattering at a given angle, rather than in terms of one-dimensional reflection or transmission. We distinguish between the incident particles (some of which may be unaffected by the target) a
