Site Masthead: Nick's Place in non-serif white text superimposed over a bright orange high contrast tinted photograph of a brick wall taken in an extreme close up. The brick is photographed with the long continuous lines of grout running vertically. The image is displayed upside-down so the disappearing point for the grout is below the image.

Nicholas Barnard PHY117: Estimating Angular Distance Discussion 2/13/02

1.

  1. My angular fist width measurement is a reasonable measurement system of large angles. The error rate is not consistent; therefore it is an unreliable measurement system because the data that is obtained cannot be accurately corrected, because not enough data about its error rate has been collected.

  2. My angular thumb width measurement is poor to moderately accurate measuring system. It has an error rate hovering around fifteen percent most of the time, but the error rate varies, which makes it an unreliable measurement because the data that is obtained from it cannot be accurately error corrected.

2. The latitude as calculated by my angular fist with is 41.48 degrees. This is a reasonably variation from the actual latitude of 39 degrees. If I were lost at sea this would probably help me, but its usefulness would be determined by the location I was seeking.

Nicholas Barnard PHY117: Spectral Classification Pre-Questions 2/13/02

  1. The Balmer series is a series of absorption lines, which get closer and closer toward the violet end of the visible spectrum. The definition of lines is strongest for type A stars, as the star gets hotter the definition of the line fades, and eventually it a smooth continuum concentrated around the ultraviolet end of the spectrum

  2. Characteristic of the Wolf-Rayet spectrum is a spectrum of emission lines.
