today was another awesome field trip. We went to NIST (National Institute of Standards and Testing) and it was awesome. We got to see alot of labs that had the most advanced measuring tools, some that I had only heard and read about. We got to talk to the researchers and ask them what they were researching and how the tool really works up close and personal. I won't get into all the different techniques, but it was nerdom at it's finest. It had a feel of getting paid to be in a well-funded grad school program for ever. Then they had a museum of Standards that had information about how they verify and set standards. Like this is a mole of Copper and a mole of liquid water. Exactly 6.o22 x 10^23 molecules. The next one is how they determine a second, exactly. It's based on the radiation cycles of a cesium 133 isotope at a specific temperature and pressure. The next one is a paper money durability tester. The white square under the metal tip is a dollar bill and they run it until the dollar wears through. Lastly, they did all the research following 9/11 and this twisted metal is all from the World Trade Centers. They had a piece inside of exactly where the plane hit. It was nice to think about real science again. Then it was back to policy in the afternoon, workout, and now I'm at home and will hopefully get a few more things done this evening before tomorrow.
