Day 13, Mat194: Mathematical Sciences Seminar

Last time

Next time

Today:

Announcements
- You have a homework due.
- Your proposal revisions are returned.
- Does anyone have any "talk reports" to hand in?
- You have a new assignment (project revision) for next time.
- Talks and events coming up:
  - This Saturday morning, 11/15, you may get two talk credits for participating in the John O'Bryan math contest. Contact Joe Nolan (MEP if you want to take advantage of that. They would love to have you, as they're short of help currently.
  - CINSAM STEM connections night, November 19th, 4:15-7:30. This is a chance to get two talk in. Thane Maynard will make this an exciting event, I'm sure. Again, if you participate in two session, you can get two talk credits.
  - Any other opportunities that you've heard of?
- Next time: we'll continue working on our projects.
Today: We have only two more sessions (after today) before the projects are presented. We'll spend some time between now and then working on these further. Today we'll get started with that. Before we begin, however, we'll talk a little bit about the last two visitors we had.
- Jen Quammen -- professional
- Regan Murray -- government employee
1. I asked Jen to share something that she didn't get a chance to discuss, and this was what she mentioned:
  One of the topics I didn't cover is heart rate variability, an interesting measure in humans and animals alike. HRV is essentially a measure of your sympathetic (fight or flight) vs your parasympathetic (rest & digest/repair) nervous systems. With a smartphone and a simple app, you can not only measure your HRV, but learn to control it. Here are a couple of links to discuss it further.

2. Regan mentioned the successful battle against DDT ("dichlorodiphenyltrichloroethane")
  
  Regan spoke about DDT, and I mentioned the notion of "bioaccumulation". We didn't have time to discuss this, but I wanted to give you a glimpse of what it means:
3. Neither of these women is "ordinary" in any way: they are both at the top of traditionally male-dominated fields. What obstacles do you think that they may have encountered simply because they were women?
With time remaining, you will discuss progress on your projects with a partner.
