I Put Up My Thumb And It

Man Must Understand His Universe In Order To Understand His Destiny.

Space Has Not Changed But Technology Has, In Many Cases, Improved Dramatically. A Good Example Is Digital Technology Where Today's Cell Phones Are Far More Powerful Than The Computers On The Apollo Command Module And Lunar Module That We Used To Navigate To The Moon And Operate All The Spacecraft Control Systems.

The Single Thing Which Makes Any Man Happiest Is The Realization That He Has Worked Up To The Limits Of His Ability, His Capacity. It's All The Better, Of Course, If This Work Has Made A Contribution To Knowledge, Or Toward Moving The Human Race A Little Farther Forward.

I Am Comfortable With My Level Of Public Discourse.

I Believe That Every Human Has A Finite Number Of Heartbeats. I Don't Intend To Waste Any Of Mine Running Around Doing Exercises.
