30th of September
Today I went into the lab for 2 hours and 15 minutes and I really wasn't getting any good images. I wasn't having trouble with the scope being really drifty. The scope was a little drifty but mostly I just couldn't find a good area and I never got a good tip. I changed the tip a couple of times and moved the sample around in order to scan different areas of the gold, but I really didn't get any good images. The images were nothing special.

2nd of October
Today Annette was scanning with the scope I use for my period in the lab and I was unable to run any scans. She continued scanning when I got there because she had a good tip and was getting very good images. I stayed at the lab for 2 hours and 15 minutes while she scanned (she scanned the entire time so I assume that her tip did not fall apart during this time period). Becky started to show me how to use her scope and in addition to this Becky gave me two papers to read. The articles are rather lenghty though and I have yet to finish reading them. Once I finish reading them I will post what I have learned from them. The two papers are "There's Plenty of Room at the Bottom" a paper by Richard P. Feynman. The second paper is a copy of Gerd Binnig and Heinrich Rohrer's Nobel lecture for STM from 1986. The Nobel Lecture also includes many diagrams. I will scan some of these into my computer and put them on the wiki.
