I arrived at Quarknet today at 3:30. I opened the file of compressed dimuon events, which was the file of 88 events, which we believe could hold evidence to cosmic rays. Dr. L showed us the file of 10k dimuon events, which had not been filled in fully. We had to fill some of it in, including the Q1*Q2 column and others. We had to copy and paste multiple column titles into the file, which we began filling in. We had to fill in all the columns in the excel file. We would copy and paste the formula from the same kind of equation from our previous graph. We filled in each of the columns with their respective equations and we dragged the formulas down, making sure we had the correct answers along the way.

This is only a small portion of the 10K Dimuon event file. It took much time to fill in each equation, with struggles such as problems copy and pasting. Each column including ßx ßy ßz ß y. These were especially hard to fill out, because we have not done anything with these columns before. Doing these columns and other portions of the excel file allowed me to explore the program and find new ways to input data. Once Jason and I had finished inputting the data, we compared our answers, some of which were different. We looked at the formulas we used and looked to find errors, which were just small mathematical mistakes, leading to different answers in both of our excel files. We fixed our graphs when we learned what we had mistakenly done. Jason and I then looked at our data to analyze it and look for things we did not understand.



Jason and I did not know what do do for this problem. It occurred in a small number of our columns, but it was quite numerous when it would show up. I had no idea what this ment, but when I asked John, he said that there was a letter or a number that could not be answered correctly in the formula, so a reasonable answer could not be found. I agreed with what John said because it seemed to be a reasonable answer, with evidence leading to a logical conclusion.

After looking at these, Dr L had us get on the lab computers to look at a excel file with at max 65K in the file, but it was only snippets of information, Dr L said it could have been a file cut to locate anomalies of some kind in the events.

Working on these excel files today really helped me gain a good amount of knowledge about how to use excel files and how to input mathematical equations into the file, without the computer or myself going crazy.

I left the Quarknet office at around 5:30 today.
