[math-fun] Draft of short piece on Ehrenfeucht-Mycielski sequence
I'd welcome comments on http://mathenchant.org/em-draft2.pdf (I already found one typo re-reading it, where I wrote "Thanks for Joel Spencer" instead of "Thanks to Joel Spencer", but it's time for me to let go of it and see what other people think.) As in the case of the two previous short pieces I posted, this piece will live two lives: first as a short Big Internet Math-Off pitch, then as a longer Mathematical Enchantments essay. There's plenty of time for you to send me feedback that'll affect the latter version, since that won't be going out until late 2019; but the BIMO pitch needs to be sent to Christian Lawson-Perfect by the 13th, so that he can post it early on the 15th. Thanks, Jim Propp
1) I would correct `Thanks for Joel Spencer' to `Thank the Lord for Joel Spencer' :-) 2) When you are lying is it your goal to make the person get it wrong? I was thinking a long the lines of I am thinking of a number between 1 and 100 and they ask ``is the number \le 30'' and you say NO since that gives a larger search space. 3) Not quite sure its lying if you don't actually have an object in mind. It is dishonest. 4) Reminds me of a blog post I did about playing binary search with my 8-year old great nephew: https://blog.computationalcomplexity.org/2007/04/getting-8-year-old-interest...

Thanks, Jim! I didn’t know about this before. I was initlaly confused by the fact that you need to include the empty string as a prefix in order to get things off the ground. You might want to work out the first few symbols as in https://en.wikipedia.org/wiki/Ehrenfeucht–Mycielski_sequence <https://en.wikipedia.org/wiki/Ehrenfeucht%E2%80%93Mycielski_sequence> . Best, Cris
