Today my obtuse anger is rightly directed toward G. H. Hardy (1877-1947) and to the followers who have accepted his view -- in his 1940 treatise, A Mathematician's Apology -- that explaining and appreciating mathematics is work for second-rate minds. Despite his worthy achievements in number theory and analysis and his nurturing of Ramanujan, Hardy's words should not stand forth and belittle those who teach and explain and forge connections between mathematics and all the rest.
An wonderful and ongoing source of integration of mathematics with the arts is the Journal of Humanistic Mathematics -- and I invite you to go to the current issue and browse there OR go to this link for more than thirty pages of mathematical Haiku.
