Cosmic Chris Experiment

From MariachiWiki

Taking Cosmic Chris to a walk may sound like a breeze. It is not.

In this experiment, Cosmic Chris went on a tour of the physics building to find any correlation between location and cosmic ray rate.

Results

Cosmic Chris measures the number of cosmic rays that went through it during a 41 second interval.

  • At each stop, 5 measurements were taken.
  • The 5 measurements were then averaged
[edit]

The Layouts

  • Each stop was marked on the layouts as Cosmic Chris was taking the tour
  • The Layouts were then scanned into the computer
  • For each layout, a color was chosen (ex. Level D=Red, Level C=Orange..)
  • For each layout, the highest value received the respective color with a saturation intensity of 90%
  • The other colors were calculated with respect to the highest value.
  • The percentage difference was calculated
  • The difference was multiplied by 7 to exagerate the color difference (by 3 in Service Level)
  • The resulting value was subtracted from the saturation intensity of 90% (ex. if the value was 30, the saturation intensity is now 60%)
  • The margin of error was accounted by taking the square root of the value
  • The original was then given a range
  • The lowest point of the range received a color, along with the highest point
  • As a result, at each station, there are three colors accounting for the original value, and taking account of margin of error

Summary

  • From the charts, it is obvious to see that the rate of cosmic rays decrease as you move from top floors to the bottom.
  • From the layouts, it is clear that the measurements taken near windows have a much higher rate than the measurements from hallways.
  • The anamolies on the Service Level can probably be best explained by the fact that some areas are separated from the physics building
  • It can be assumed that cosmic rays are absorbed by the building
