Wednesday
This week, I was sick on Monday and unable to come into Quarknet. I was told by Grace what work was done, and it seems that they continued to analyze the graphs on ManyEyes. I arrived today at 3:40, and Dr. Loughran explained to me where we were to go with our next project. The place we were to go next is as follows: 1. Pull CSV file into Excel 2. Create a new column of (E1 + E2) / m 3. Sort the data with that 4. Isolate the cosmic rays in the data

For the sake of ease, the majority of my posts for today will be located on the previous week underneath each graph so that I do not have to re-import every photo.

A couple more graphs that I found interesting on ManyEyes:



While a graph of a straight diagonal line like this usually means that we have graphed something needlessly against itself, this graph actually gives insight on the nature of the particles. This graph, as can be seen, has a slope of 1/2, instead of 1. Because i graphed the E1 vs E sum, it can be inferred that each daughter particle from each collision has exactly the same energy as the other particle. This is due to the law of conservation of momentum. If one daughter particle had greater energy than the other, the parent particle would accelerate in the direction opposite of the larger force exerted. This graph reinforces this basic law.

This final graph represents the sun of the energy of the daughter particles on the y-axis, and the total momentum of the daughter particles on the x-axis. This is an interesting graph because we first notice a limit below a certain line (y = 2x). This makes sense, as the momentum of one particle is expected to be half the momentum of the sum of two particles. Also noticeable, the line begins at an energy sum value of 40, and a pt1 value of 20. This pt1 value of 20 means that the sum of both particles added together would be 40, as seen in the value of the y-axis.
