(I write it that way because there are things folks call spambots that look for email addresses. This way I'm hoping ony humans can figure it out.)<br /><br />Thank you for your super sweet comments. I wish my son had been with me. I'll be back in Muskegon in December, and we'd love to say hi. (I would, and he might.) ;^) Please keep in touch.<br /><br />I think I told you that last school year was rough. Well, this year is starting out wonderful. Thanks for helping to pump me up!Sue VanHattumhttps://www.blogger.com/profile/10237941346154683902noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-86240497012496999292011-08-26T00:10:22.569-07:002011-08-26T00:10:22.569-07:00Sue,I'm glad that you wanted to keep in touch ...Sue,I'm glad that you wanted to keep in touch with me again after the MCC math conference in Muskegon. I know that I am a hopeless romantic in terms of Mathematics and calculations beyond Calc, but I know that if I had been blessed with you as my instructor for more than a part time credit on Math I would have been flawless. Best wishes Sue from Calvin :). Hope the little one is well. You have many friends, even those whom you have just met again recently and have forgotten. A great person does not remember those whom remember them. You have no idea how much you have greatly influenced the lives of people who "WANT" to explore the art of math that were prior uninterested.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-89938959523602062492011-08-23T03:01:28.860-07:002011-08-23T03:01:28.860-07:00In case you're interested, here in the UK (I d...In case you're interested, here in the UK (I don't know about elsewhere) we have coins (20p & 50p) that have constant diameter that are not circles. They are 7-sided versions of the shapes in your Cut the Knot link. Apparently done that way to make it easy for vending machines, etc. to recognise the coin based on its size even though they're not circles.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-69654543470299812662011-08-20T08:25:51.323-07:002011-08-20T08:25:51.323-07:00I like the way A's definition begins to separa...I like the way A's definition begins to separate the topology from the geometry. "A shape with no beginning and no end" is not really a topological definition of a circle, but it's getting there. And one can think of geometry as really being about the symmetries of something (but first, about what it is that the symmetries are supposed to preserve, that is, what it means to be a symmetry). So "that's symmetrical" is also pointing in a really good direction.Davidhttps://www.blogger.com/profile/10565910956857563935noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-85422668572033410782011-08-18T11:52:01.189-07:002011-08-18T11:52:01.189-07:00I think I asked for different people to do each pr...I think I asked for different people to do each problem. I do know there were a few no one solved.<br /><br />I am playing this by ear so far - it's new for me.<br /><br />I won't be blogging about today's class, it was a bit boring. I was hoping I could make it shine like yesterday. I'm thinking I need to have group work between lectures, so they don't fall back into passivity.Sue VanHattumhttps://www.blogger.com/profile/10237941346154683902noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-23877479081155524972011-08-18T10:42:34.360-07:002011-08-18T10:42:34.360-07:00Thanks for the detail Sue -- it's interesting ...Thanks for the detail Sue -- it's interesting and helpful. I'd like to use "Find questions you can't do" with my class. I like the idea of putting the tough ones on the board. But every semester I have one or two students who can solve just about any textbook question. What would you do if one student solved every question on the board? Is this even a problem?Anonymousnoreply@blogger.com
