OK Go has been amazing me with their music and videos for 12 years, and now they've done it again! Truly awesome. And simply the feat of how many people it took to make that video is one thing that makes it so fabulous.

"[If] people use data and inferences they can make with the data without any concern about error bars, about heterogeneity, about noisy data, about the sampling pattern, about all the kinds of things that you have to be serious about if you’re an engineer and a statistician—then you will make lots of predictions, and there’s a good chance that you will occasionally solve some real interesting problems. But you will occasionally have some disastrously bad decisions. And you won’t know the difference a priori."

"In response to the lackluster high school math performance, some influential voices in American education policy have suggested simply teaching less math -- ... The subtext, of course, is that large numbers of American kids are simply not born with the ability to solve for x."
Thanks to Betsy Blake for sharing this with me!

A graph is planar if it can be drawn in a plane (two dimensions, ie on a piece of paper) without graph edges crossing.
A subdivision of a graph G=(V,E) is a graph resulting from taking an edge e in E with endpoints u,v in V, introducing a new vertex w, and replacing e with two new edges, one between u,w and one between w,v.
Kuratowski's Theorem states that a graph with a finite number of vertices V and edges E is planar if and only if it does not contain a subgraph that is a subdivision of (1) the completely connected graph on five vertices or (2) the complete bipartite graph on six vertices, three in each partition.

Priya was always so fun to be around; she worked so hard and embraced everything so fully. She will live on in all of us if we try to be just a little less hesitant and jump in feet first to helping the people around us.

"Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, which can always be made precise." - John Tukey.
