Dedication
I would like to dedicate The Pythagorean Theorem to:
Carolyn Sparks, my wife, best friend, and life partner for
40 years; our two grown sons, Robert and Curtis;
My father, Roscoe C. Sparks (1910­1994).
From Earth with Love
D o you remember, as do I,
When Neil walked, as so did we,
On a calm and sun-lit sea
One July, Tranquillity,
Filled with dreams and futures?
For in that month of long ago,
Lofty visions raptured all
Moonstruck with that starry call
From life beyond this earthen ball...
Not wedded to its surface.
But marriage is of dust to dust
Where seasoned limbs reclaim the ground
Though passing thoughts still fly around
Supernal realms never found
On the planet of our birth.
And I, a man, love you true,
Love as God had made it so,
Not angel rust when then aglow,
But coupled here, now rib to soul,
Dear Carolyn of mine.

Conceptual Use of the Pythagorean Theorem by
Ancient Greeks to Estimate the Distance
From the Earth to the Sun
Significance
T he wisp in my glass on a clear winter’s night
Is home for a billion wee glimmers of light,
Each crystal itself one faraway dream
With faraway worlds surrounding its gleam.
And locked in the realm of each tiny sphere
Is all that is met through an eye or an ear;
Too, all that is felt by a hand or our love,
For we are but whits in the sea seen above.
Such scales immense make wonder abound
And make a lone knee touch the cold ground.
For what is this man that he should be made
To sing to The One Whose breath heavens laid?
