Math Photo: Orthogonal Trajectories
This lovely photo was taken by mathematician Peter Krautzberger. Peter knows that I enjoy photographing mathematics, so he shared this great image with me. And he graciously let me share it here, and approved of the title.
I often admire crossing contrails high above in the sky, but I can’t say I’ve ever seen two so perpendicular!
Peter is a friend and colleague from MathBlogging.org, where he is a co-founder. Peter also works on MathJax, and is consumed by publishing math on the web. You can follow him on Twitter at @pkrautz. Thank you, Peter, for sharing!
