QUATTRO is a series of paintings constituting one art work.
The name is Italian for four, meaning the four fundamental forces of physics: The electromagnetic force, the gravitational force, the strong force and the weak force.
Each painting is 50 inches high and the width varies as can be seen clearly in the picture showing the painting on the studio wall.
The center painting is 40 inches wide.
All the painting is in watercolor on Arches 100% cotton paper

Special thanks and appreciation to Richard Feynman... gone from this Earth... but give to all of us so much greater understand of Science and his wonderful Feynman diagrams which I have use extensively through out this painting.

Special Thanks also to the well known physicist, professor and author Dr. Kenneth Ford who gave me understanding and courage to continue with this work which was well over my head.
And thanks also to Vahid Huston Ranjbar a distinguished physicist who gave me answers to questions.
