Based on our informal study with a sample size of 2, fireknife dancing and operating a freezer are equally dangerous.

"Wait. Your business plan is to wait until the room smells interesting and then capture it in a candle?"

@vwbusguy Scientists aren't sure exactly how eels reproduce.

My mother adds, "and when you find out, don't tell them, because I don't want any more."

I wired the brick up as a very small external monitor, so you can, for instance, play Doom on it.

@ancientjames ... so it's got at least as much computational power as a pregnancy test.

A group of people in a room staring at their phones. Every half hour or so a different one looks up and complains about how everyone else does nothing but look at their phones.

Title for a book recommendation blog:

A Danger to My Shelf and Others

Hint, not a solution 

@Placholdr I'm not sure if this will work, but here's an approach:

Use contraction. Assume a_n *is* a perfect square. Consider all possibilities for the square root's last digit. It can't be even, because squaring an even number gives another even number. That leaves 1, 3, 5, and 9. ***1^2 (that is, squaring a number that ends in 1) ends in 1. ***3^2 ends in 9, ***5^2 ends in 5, and ***9^2 ends in 1. So the proposed square root must end in 1 or 9. Explore those possibilities and see if you can eliminate them.

Alternately, maybe the old algorithm for taking square roots by hand is useful.

Again, these may be dead ends.

Honest question: Is there anyone here fluent in both and who prefers R?

I know Python well and am still learning R. It feels kludgy, extremely context-sensitive, and more like an accreted bag of tricks than a designed programming language.

Maybe this is just my fear of change / computer scientist bias or issues with the particular book I'm reading. A part of me feels that students minoring (and someday majoring) in should know R because it's widely used, but another part worries that teaching them this inferior tool is doing them a disservice.

Is there an R champion in the house?
