Groceries, Carts, and Electron Microscopes


I had my first Microbiology lab today, and while it did seem a little tedious at times, it was also quite interesting. It was certainly my first exposure to an actual electron microscope, which is quite useful for viewing bacteria. They are sizeable machines, and the price tag isn't so small either. Just one of them will put you back a good $300,000. I also saw an eSEM (environmental Scanning Electron Microscope), which was almost cooler than the former. It takes topographical scans, allowing you to see microscopic structures as if they were life size. They had a fluit fly's head blown up to poster size. That machine was quite loud, and I can only surmise that this was the pump to keep a vaccuum in the chamber. I went afterward to Costco, Wal-mart, and Superstore. I picked up a heck of a lot of grcoeries and assorted other junk. I got the job done, but carrying the 45 pounds in my arms for 2 miles had them shaking by the time I got back to my room. Needless to say, I am more than ready to call it a night and see what tomorrow brings.
