Are You Really Sure That A Floor

I Can't Keep From Fooling Around With Our Irrefutable Certainties. It Is, For Example, A Pleasure Knowingly To Mix Up Two And Three Dimensionalities, Flat And Spatial, And To Make Fun Of Gravity.

It Has Always Irked Me As Improper That There Are Still So Many People For Whom The Sky Is No More Than A Mass Of Random Points Of Light. I Do Not See Why We Should Recognize A House, A Tree, Or A Flower Here Below And Not, For Example, The Red Arcturus Up There In The Heavens As It Hangs From Its Constellation Bootes, Like A Basket Hanging From A Balloon.

The Regular Division Of The Plane Into Congruent Figures Evoking An Association In The Observer With A Familiar Natural Object Is One Of These Hobbies Or Problems...i Have Embarked On This Geometric Problem Again And Again Over The Years, Trying To Throw Light On Different Aspects Each Time. I Cannot Imagine What My Life Would Be Like If This Problem Had Never Occurred To Me; One Might Say That I Am Head Over Heels In Love With It, And I Still Don't Know Why.
