Albert Einstein

We can not solve our problems with the same level of thinking that created them.

W. H. Auden

We are all here on Earth to help others; what on Earth the others are here for I don't know.

Howard Aiken

Don't worry about people stealing your ideas. If your ideas are any good, you'll have to ram them down people's throats.

Carl Sagan

Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children’s or grandchildren’s time — when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness.

The Doctor

Me? I am the Doctor.

Dorothy Parker

The cure to boredom is curiosity. There is no cure for curiosity.

Sir Winston S. Churchill

It is a mistake to try to look too far ahead. The chain of destiny can only be grasped one link at a time.

Oscar Wilde

What seems to us as bitter trials are often blessings in disguise.

Mark Twain

The difference between the right word and the almost right word is the difference between lightning and a lightning bug.

Thomas Jefferson

The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants. It is it’s natural manure.

Beverly Sills

There are no shortcuts to any place worth going.

John F. Kennedy

Those who make peaceful revolution impossible will make violent revolution inevitable.

Lou Reed

There is no God. And Brian Wilson is his son.

Master Yoda

Fear leads to anger. Anger leads to hate. Hate leads to suffering.

Yakko Warner (Animaniacs)

Early to rise, early to bed, makes a man healthy, but socially dead.
