Math Art: Hamid Naderi Yeganeh

Hamid Naderi Yeganeh, a Bachelor student of mathematics at the University of Qom, Iran, sends captures of his Math Art to celebrate Joseph-Louis Lagrange’s birthday on WUMATH (January 25, 1736).

Yeganeh won a gold medal at the 38th Iranian Mathematical Society’s Competition in 2014. His works have been featured on the web site of the AMS, see http://www.ams.org/mathimagery/thumbnails.php?album=40,
and on the site of The New York Times http://wordplay.blogs.nytimes.com/2015/01/05/moriconi/.

We define A(n) for n=1,2,3,...,800 :

## Corridor

Shows 400 line segments. For each i=1,2,3,...400 the endpoints of the i-th line segment are A(i) and A(i+199).

## Star

Shows 400 line segments. For each i=1,2,3,...400 the endpoints of the i-th line segment are A(i) and A(i+150).

## Matrix

Shows all line segments of the form
,

for i=1,2,3,...,99 and j=2,3,4,...,100 such that i<j.
