About Xander

Xander is interested in pure mathematics and mathematics education. He holds a bachelor's degree in mathematics with an emphasis in statistics from the University of Nevada, Reno, and has completed a teacher preparation program at the same institution. After completing his student teaching, he was unable to find gainful employment as a teacher, and has therefore retreated behind the ivory walls of academia in order to complete a master's degree in mathematics. As part of a teaching assistantship designed to help defray the cost of his education, Xander is also teaching remedial algebra at the university.

LEGO Fractals

My daughter has recently started playing with DUPLO blocks pretty consistently, which has me thinking about LEGO—the toy of my youth (and hopefully her’s in a couple of years, too!). In some ways, LEGO is an ideal medium for exploring … Continue reading

Lunar Eclipse

A propos of nothing in particular, and with minimal commentary, a couple of pictures of last night’s lunar eclipse (rollover either picture for annotation or click for a larger version): While the moon was lovely, the proximity of the eclipsed … Continue reading
