More solar numbers

     Yesterday's eclipse is still on my mind -- and "solar" links me to a poem featured at the recent Bridges Math-Arts Conference in Waterloo -- a poem by Brazilian poet Marco Lucchesi, a much-honored and widely translated writer who is a professor of literature at the Federal University of Rio Di Janeiro.
 

by Marco Lucchesi

Lucchesi's poem is found in Hinos Matematicos (Mathematical Hymns) -- and has been translated from the Portuguese by Renato Rezende.  The numbers in the poem, 220 and 284, are in mathematics called amicable numbers  -- the proper divisors of each one can be summed to give the other.   For example:   (2 + 110) + (4 + 55) + (5 + 44) + (10+22) + (11+20) + 1 = 284.

Thanks, Marco, for your poem.
