Comment on On Mobius transformations by Bill Lionheart

I am currently working on using EIT to help with monitoring intensive care patients who are mechanically ventilated. As they breathe their chest shape changes. The electrical data we measure determines this chest shape up to a Mobius transformation. Conformal geometry here hopefully in the service of medicine and eventually saving lives.

As Bill Clinton had put it brilliantly, and when everything else about him is forgotten it will still shine, “it all depends on what ‘is’ is.” Just apply it to “for every epsilon there is delta bla-bla-bla…”

Here we go again… “Comfortable with limits,” but not understanding what they mean…

It is precisely for this reason that I have always regarded Piet Mondrian as a landscape painter. Flying low over The Netherlands is like looking at a Mondrian painting.

Comment on I need your stories by Sue

When I read your request, I thought I’d never had problems with math when I was young. But, like Tommi, I couldn’t remember which way division went. Of course, it’s made harder by the fact that it goes either way, depending on the symbol: 6 divided by 3 is the same as 3 gazinta 6.

But my inability to remember that didn’t get in my way. If I saw a division problem with harder numbers, I just put 3 and 6 in their place for a moment, to orient me, and then I knew what was being asked.

[You asked for problems from when we were young, but in college, doing proofs was a huge hurdle.]
