The water's fine! If you've been invited to post to the blog, you can do so. Also note that *anyone* can comment. Some teachers are offering extra credit for blogging at least 5 relevant sentences about a science seminar session. Why not go for it? Here's my five sentences.
Regarding this evening's lecture by Dr. David Saloner, I was pretty amazed by how they could create 3-D maps of the arteries and then measure the blood flow through various parts of them. Then they can look at the same arteries over a period of years and tell how they had changed. They could tell the change both in terms of how fast or slow the blood was flowing in different areas, and in how big the arteries were getting because of arteriosclerosis. This helps not only charting the progress of the disease, but also helps see how different medical therapies might be working over time. It made me wish that I had taken more math in school and made me glad that the kids at the MSS were getting to see all the cool things you can do with math. I didn't get to see that when I was in high school.
