that's how I learn stuff about what we do in the course and how to improve it. So yes, MIT would like you to please fill out the formal evaluation form and we'll live with whatever the numerical score is, whatever that means. But we really would like to learn something from you. No, we made a decision to have guest presenters, particular guest presenters. Did we make good choices? Did we give them good advice about how to structure what they were presenting? Anamesh and I tried to provide the water diplomacy framework in some more expository way at the outset. We ask everyone to pick a case and write a case. We use the aquapedia frame so that people have some common device because it's worth it because we've put, publish your paper in the aqua pedia. I mean, so we make a bunch of decisions. Those could all be different. Yeah, and also last thing I would like to mention that last year, two students, so one of the students was able to submit their final paper into a journal article. So it's already submitted in one of the journal article. Another student is still working on that. And another student was able to publish their article in a newspaper. So this kind of thing says, these are the practical things. So all these are the possibilities that you can do and I am happy to support you. So yeah
