The Drake Equation T-Shirt
How can we estimate the number of technological civilizations that might exist among the stars? While working as a radio astronomer at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake (currently on the Board of the SETI Institute) conceived an approach to bound the terms involved in estimating the number of technological civilizations that may exist in our galaxy. The Drake Equation, as it has become known, was first presented by Drake in 1961 and identifies specific factors thought to play a role in the development of such civilizations. Although there is no unique solution to this equation, it is a generally accepted tool used by the scientific community to examine these factors. --Frank Drake, 1961

Have had Zazzle complete a number of T-shirt projects in the past. This one had several design elements. It was well done. I will work with Zazzle again.

The T shirt seems to be made from decent material but appears to be an irregular t-shirt sewn and stitched. .

Our Girl Scouts were bridging to adult and our troop dad was always there to lend a helping hand. We wanted to do something special for him so we put special pictures on the front and a note on the back. It brought a tear to his eye. .
