World Nursery Rhyme Week

 On X I learned that this week -- November 10-14, 2025 -- is World Nursery Rhyme Week, and I searched and found this website that offers information about the week and these "5 official rhymes for 2025":

    Monday, 10th -- Sing a Song of Sixpence  
         Tuesday, 11th -- Humpty Dumpty
    Wednesday, 12th -- When I Was One (I played the drum)
         Thursday, 13th -- I Hear Thunder
     Friday, 14th -- Two Little Dickie Birds

Here at this website are all of the above except "Two Little Dickie Birds" -- which I offer a version of below.  (Here in Wikipedia is more about that rhyme.)

Science Verse

Recently coincidence has brought to me two collections of poems about  science -- first, the 2014 issue of The Nassau Review, a gift from editor and poet Christina M. Rau. The second collection is a "used" children's book, Science Verse (by John Scieszka and Lane Smith) found at the wonderful Kensington Row Bookshop (scroll down their webpage to find out about their monthly poetry readings).  I include below two rhyming stanzas from Science Verse, followed two selections from The Nassau Review 2014 -- a poem by Diane Giardi which is a parody (or isomorphic image) of a nursery rhyme and a poem  by Katherine Hauswirth which may or may not consider infinity.

Hey Diddle Diddle

Hey diddle diddle, what kind of riddle

Is this nature of light?

Sometimes it's a wave,

Other times a particle . . .

But which answer will be marked right?
