Visiting the crematorium of the dinosaurs
While filming a TV documentary about asteroid impacts, I visited a park in Colorado where the geologic layer marking the mass extinction of the dinosaurs is really easy to see. I decided to make my own short video so I could say a few things that didn't get in to the documentary. I have to say, it was surpassingly cool to stand (well, squat) there and see the K-Pg boundary with my own eyes.

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

However, if we eliminate the magnetic field instead, we can derive the following equation for the current density:
