Ever wanted an interactive lightning-fast solver for models in physics, chemistry, or biology? Do you have a web browser? I'm thrilled to announce VIsualPDE.com, built explicitly to solve PDE models interactively on most devices, written by @bj_w95 @Pecnut and I.

VisualPDE

VisualPDE brings interactive science and mathematics to the web. Explore examples like waves and reaction—diffusion patterns, or create your own simulation.

Why did @Canvas_by_Inst make it so you don't see the full history of comments on an assignment, but now they are only visible by submission attempt? This is such a pain! I can't see my old feedback while evaluating a new submission.

Having chosen cairns as a symbol of their annual theme, @Ch_JesusChrist should also educate about harmful impacts of creating these in the wild. ecologyforthemasses.com/2019…

STOP BUILDING CAIRNS

So if stacking rocks is going to be a part of an activity, be careful not to disrupt the environment and take them down before leaving to #LNT leave no trace.

Last week I attended @JointMath, the largest annual mathematics meeting in the world. It was such a full circle moment for me. I went to JMM the first time 11 years ago (also in Boston) because I heard that’s where the mathematicians would be, and I desperately wanted to be one.

My Nancy Pelosi story. My son died on January 3, 2015. The funeral & first night of shiva were on Jan 6. Congress had just convened, was in session. Nancy came to the shiva—and stayed for 3 hours. She had every reason not to be there, or just make a brief stop. She is a Mensch.

This requires new decision variables for identifying students who do duplicates so that I can have an objective that measures this quantity. 8/8

And the revised model actually showed an assignment without duplicates. Because I had a conflict between constraints.
Or what I should have suspected at the time, one of the constraints was miscoded.
