There Is Time For Everything.

I Never Pick Up An Item Without Thinking Of How I Might Improve It.

Incurably Religious, That Is The Best Way To Describe The Mental Condition Of So Many People.

When There's No Experimenting There's No Progress. Stop Experimenting And You Go Backward. If Anything Goes Wrong, Experiment Until You Get To The Very Bottom Of The Trouble.

I Speak Without Exaggeration When I Say That I Have Constructed 3,000 Different Theories In Connection With The Electric Light, Each One Of Them Reasonable And Apparently Likely To Be True. Yet Only In Two Cases Did My Experiments Prove The Truth Of My Theory. My Chief Difficulty Was In Constructing The Carbon Filament... Every Quarter Of The Globe Was Ransacked By My Agents, And All Sorts Of The Queerest Materials Used, Until Finally The Shred Of Bamboo, Now Utilized By Us, Was Settled Upon.

Because Ideas Have To Be Original Only With Regard To Their Adaptation To The Problem At Hand, I Am Always Extremely Interested In How Others Have Used Used Them.
