All Numbers are Interesting . . .

     For math poetry and math art and a host of enticements to love math if you don't already, I recommend a visit to Grant Sanderson's website 3blue1brown.   Here are the opening stanzas of one of his fascinating poems:

       Moser's Circle Problem

       Take two points on a circle,
       and draw a line straight through.
       The space that was encircled
       is divided into two.

       To these points add a third one,
       which gives us two more chords.
       The space through which these lines run
       has been fissured into four.
           . . .

Read all of this poem AND watch a video here.

Euler formula poem

     Sometimes I try to write a poem that explains a mathematical concept -- it's a difficult task  My effort usually results in something that sounds more like a textbook paragraph than a poem.  And I was thereby hugely delighted (following a lead from Colm Mulcahy) to discover this poem by Grant Sanderson that has fun with a famous mathematical formula due to Euler:

e^iπ + 1 = 0     or, stated differently      e^iπ = -1

Euler Formula    by Grant Sanderson 

Famously
start with e,
raise to π
with an i,
we've been taught
by a lot
that you've got
minus one.
