I put instant coffee in a microwave oven and almost went back in time.

If I had a time machine, I’d visit Marilyn Monroe in her prime or drop in on Galileo as he turned his telescope to the heavens.

It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.

It is the weight, not numbers of experiments that is to be regarded.

Do you think that when they asked George Washington for ID that he just whipped out a quarter?

When I write about a 15-year old, I jump, I return to the days when I was that age. It’s like a time machine. I can remember everything. I can feel the wind. I can smell the air. Very actually. Very vividly.

In my own work, I tend to cover a lot of time and to jump back and forward in time, and sometimes the way I do this is not very straightforward.

In this experiment, made on the 9th of October, 1876, actual conversation, backwards and forwards, upon the same line, and by the same instruments reciprocally used, was successfully carried on for the first time upon a real line of miles in length.

You never know with these things when you’re trying something new what can happen. This is all experimental.

Music is changing so quickly, and the landscape of the music industry itself is changing so quickly, that everything new, like Spotify, all feels to me a bit like a grand experiment.

That our government should have been maintained in its original form from its establishment until now is not much to be wondered at. It had many props to support it through that period, which now are decayed and crumbled away. Through that period, it was felt by all to be an undecided experiment; now, it is understood to be a successful one.

Don’t be too timid and squeamish about your actions. All life is an experiment.

Time travel used to be thought of as just science fiction, but Einstein’s general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

I had been playing for a while, and I asked Louisville Slugger to send me a dozen flame treated bats. But when I got it, I realized they had sent me a box of ashes.

When a coil is operated with currents of very high frequency, beautiful brush effects may be produced, even if the coil be of comparatively small dimensions. The experimenter may vary them in many ways, and, if it were nothing else, they afford a pleasing sight.

How could youths better learn to live than by at once trying the experiment of living?

If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we’re ever likely to do that is by going into space.

The situation in the sciences is this: A concept or an idea which cannot be measured or cannot be referred directly to experiment may or may not be useful. It need not exist in a theory.

It’s not an experiment if you know it’s going to work.

When I was 16… I worked in a pet store. And they fired me because… they had three snakes in there, and one day I braided them.

It vexes me when they would constrain science by the authority of the Scriptures, and yet do not consider themselves bound to answer reason and experiment.

All life is an experiment. The more experiments you make the better.

There was a girl knocking on my hotel room door all night! Finally, I let her out.

The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C – not much good for defrosting the pizza, let alone cooking it.

Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.

Every experiment, by multitudes or by individuals, that has a sensual and selfish aim, will fail.

Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a ‚crank.‘

I have no fear that the result of our experiment will be that men may be trusted to govern themselves without a master.
