One day every major city in America will have a telephone.
Alexander Graham Bell
Image
Leave the beaten track behind occasionally and dive into the woods. Every time you do you will be certain to find something you have never seen before.
Alexander Graham Bell
Image
We are all too much inclined, I think, to walk through life with our eyes shut. There are things all round us and right at our very feet that we have never seen, because we have never really looked.
Alexander Graham Bell
Image
I have heard articulate speech produced by sunlight I have heard a ray of the sun laugh and cough and sing! … I have been able to hear a shadow, and I have even perceived by ear the passage of a cloud across the sun's disk.
Alexander Graham Bell
Image
Don't keep forever on the public road, going only where others have gone and following one after the other like a flock of sheep. Leave the beaten track occasionally and dive into the woods.

When one door closes, another one opens.
Alexander Graham Bell
Image
Leave the beaten track behind occasionally and dive into the woods.
Alexander Graham Bell
Image
Wherever you may find the inventor, you may give him wealth or you may take from him all that he has and he will go on inventing. He can no more help inventing that he can help thinking or breathing.
Alexander Graham Bell
Image
The inventor is a man who looks around upon the world and is not contented with things as they are. He wants to improve whatever he sees, he wants to benefit the world he is haunted by an idea. The spirit of invention possesses him, seeking materialization.
Alexander Graham Bell
Image
There cannot be mental atrophy in any person who continues to observe, to remember what he observes, and to seek answers for his unceasing hows and whys about things.
Alexander Graham Bell
Image
Sometimes we stare so long at a door that is closing that we see too late the one that is open.
Alexander Graham Bell
Image
When one door closes, another opens but we often look so long and so regretfully upon the closed door that we do not see the one which has opened for us.
Alexander Graham Bell
Image
Watson, ... if I can get a mechanism which will make a current of electricity vary in its intensity, as the air varies in density when a sound is passing through it, I can telegraph any sound, even the sound of speech.
Alexander Graham Bell

Neither the Army nor the Navy is of any protection, or very little protection, against aerial raids.
