The Learn Fun Facts blog posted an interesting fun fact about strings. Law’s fun fact is that 8+9+1+89+91=198. Why is this a fun fact? Because the left side of that equation takes every sequence of digits from 891 (except the whole thing) and adds them together to get the digits in reverse order. Contrary to Law’s statement, though, this is not the only three digit number … Continue reading

I’m a fan of LaTeX. I like it for several reasons, one of them being easy use of logical symbols. There are a lot of guides to using LaTeX. To my knowledge, none … Continue reading Enough LaTeX for basic logic typesetting

Disorder in multiple dimensions

This is a fun post. Clearly a similar argument can be ran to show the unorderedness of any other field with a rotational operator that just adds dimensions to the reals/complexes (quaternions, octonions, etc.) but I do wonder if either some other property (say, completeness) can be given up to get orderedness or else if some nonstandard field with non-flat geometry can be ordered. (And … Continue reading Disorder in multiple dimensions
