So what is this blog all about, anyway?
Quite simply, this blog is dedicated to exploring beautiful mathematics.
Math? Beautiful? Yeah, right.
No fair, that’s not a question. But anyway, if you can’t understand how anyone could use the words “math” and “beautiful” in the same sentence, then I dare you to stick around a bit and see if you don’t change your mind. Math is about much more than figuring out when two trains will meet or calculating compound interest. Mathematics — like the hard sciences, but even more so — seeks to discover and understand the deep, elegant structure built into the very fabric of the universe. And it’s no surprise, really, that the deep mathematical structure of a universe featuring such things as clouds, crystal lattices, rainbows, galaxies, and atoms turns out to be beautiful. Personally, I see mathematics — and all beautiful structure in the universe — as evidence of a Creator at its source, but of course you can still appreciate it without sharing that belief.
I like it but I will never remember to come back here every now and then to check for new entries.

What level of mathematics do I need in order to understand the stuff you write about?
My posts are targeted mostly at the high school level — if you’ve taken (or are taking) Algebra II, you’ll probably have most of the tools you need to understand most of what I write. But there will probably be lots of stuff at many different levels, so don’t let that scare you away (or conversely, don’t let that convince you that you will be bored). And if there’s something you don’t understand, let me know, and I’ll try to explain it to you.
Why the high school level?
There is tons of beautiful mathematics out there which is accessible without an advanced degree in mathematics — but not much of it is taught in high school, either because teachers do not have a good grasp of the mathematics outside their set curriculum, or because it is deemed “irrelevant” or “not useful”. While I agree that one goal of education is to make sure students acquire useful skills, certainly another goal is to arouse students’ wonder and curiosity — and this is where current mathematical education (at least in the U.S.) seems to fail so miserably. I doubt this little blog can ever really make up for such a big hole in modern math curricula, but at least I hope that a few students might read it and be inspired to consider that maybe — just maybe — math isn’t quite so boring as they thought…
The Math Less Traveled? Huh?
It’s a punning reference to the famous Robert Frost poem “The Path Less Traveled”. Two paths diverged in a yellow wood… You’ve probably heard of it.
Well, actually, you probably haven’t, since it doesn’t exist; the astute student of English literature will at this point jump in to object that the real title of the poem is “The Road Less Traveled”, not Path, and it actually goes Two roads diverged in a yellow wood… Right, sorry about that. Hopefully you can forgive my artistic license.
At this point the very astute student of English literature will jump in to object that the poem is actually entitled “The Road Not Taken“, and that furthermore it does not even use the phrase “the road less traveled”, much less “path”. Well… hrmph. At any rate you can read it here.
So, how does this blog actually work? How do you get those cool-looking formulas in your posts?
The Math Less Traveled is hosted by WordPress.com, which supports using for inline mathematics. is a powerful mathematics typesetting system which is the accepted standard in mathematics and science publishing, and allows you to quickly and easily typeset complicated mathematical equations (and whole papers including them). It is completely free and there are versions which run on Windows, Macs, and Unix/Linux. If you’re interested in learning more about it, visit the Comprehensive TeX Archive Network at ctan.org.
Can I use something you wrote on my own blog/in a math competition/to make copies to give to my students/as the basis of a short story/in a chapter of the book I’m writing in order to become filthy rich?
Yes, yes, yes, yes, and no. For details, see the license.
