Back to the Future

"I believe that mankind has the capacity to achieve great things if we work together."

"A good scientist never dismisses the impossible until all possibilities are exhausted."

"Patience, Marty. Everything takes time in the pursuit of knowledge."

"The past is fixed. The future is always in motion."

"Great Scott, McFly! You've got to see this!"

"I've dedicated my life to scientific inquiry and discovery."

"One point twenty-one gigawatts! What in God's name is wrong with these circuits?"

"The flux capacitor is the key to everything."

"A scientist must be willing to challenge conventional wisdom."

"In the future, we'll solve all the world's problems through science and reason."

"Temporal mechanics suggests that time is not a straight line but rather a series of possibilities."

"Marty, you've got to understand that if you put your mind to it, you can accomplish anything."

"The space-time continuum is not something to be taken lightly."

"I find that if you apply yourself, there's no limit to what you can accomplish."

"Whatever happened, happened. We can't change the past."

"You see, Einstein has just theoretical physics. I've built a time machine!"

"There's that word again. Heavy. Is there something wrong with the Earth's gravitational pull in the future?"

"I'm not afraid of the future anymore. I'm going to go out there and make my own destiny."

"The proper utilization of the scientific method would suggest that we must conduct experiments."

"This is it! This is the answer! It says here that a bolt of lightning is going to strike the clock tower at precisely 10:04 PM next Saturday night."

"Science rules!"

"A man can change his destiny if he really wants to."

"I've always said that if you put your mind to it, you can accomplish anything."

"The whole thing is insane! There's no way it should work!"

"1.21 gigawatts! 1.21 gigawatts! Great Scott!"

"Where we're going, we don't need roads."

"Your future hasn't been written yet. No one's has. Your future is whatever you make it."

"Nobody calls me chicken!"

"I'm your density. I mean, your destiny."

"The way I see it, if you're gonna build a time machine into a car, why not do it with some style?"
