In Einstein's equation, time is a river. It speeds up, meanders, and slows down. The new wrinkle is that it can have whirlpools and fork into two rivers. So, if the river of time can be bent into a pretzel, create whirlpools and fork into two rivers, then time travel cannot be ruled out.

Michio Kaku

It turns out all molecular and biological systems have speeds of the atoms move inside them; the fastest possible speeds are determined by their molecular vibrations, and this speed is about a kilometre per second.

Ahmed Zewail

Mostly, I would like people to ask other writers about the craft of their writing so we could learn from one another. We ask movie directors why they chose to use certain lights and angles and speeds of film, but most of the time, we ignore the craft of a writer.

Alexandra Fuller

I have two speeds, nothing and full pelt.

Andre Rieu

If the E.U. formally becomes a union of different speeds it would in effect be formally divided into better and worse members and it would to a large extent lose its attractiveness for those countries that were deemed second class.

Andrzej Duda

Thus I was able to make pioneering measurements of the height and physical scale of plasma clouds in the ionosphere and also to estimate wind speeds in this region.

Antony Hewish

U.S. Speedskating has been riddled with problems since when I started my career, and we were always able to look past that. When it came down to performing on the ice, regardless of funding issues, we were always able to make it happen. And that's what it's all about.

Apolo Ohno

I happen to love engineering. I love figuring things out in a spatial sense, that whole realm of working with mechanical parts, and the relationship of the parts, and things like ratios and the speeds of particular objects.

Arthur Ganson

In financial services, the front end of the world operates at super-high speeds: comparative advantages are measured in fractions of nanoseconds. And yet back end processes - the amount of time you have to wait when you sell a stock before cash hits your account - can take days.

Blythe Masters

It's frightening, the way life speeds up. When you're at school, time can't go fast enough.

Bruce Forsyth

And when I first came out from New York, I hadn't driven in a long time. Now I'm like Joe Speedster.

Calista Flockhart

I trained for months to figure out how to ride a motorcycle. I have kind of a major fear of them. I have a major fear of going at fast speeds without any kind of protection, no helmet, an actor on the back with no helmet. I felt very afraid to do it. I love that I did it and overcame the fear and was able to do that.

Carrie-Anne Moss

Common sense and a sense of humor are the same thing, moving at different speeds. A sense of humor is just common sense, dancing.

Clive James

The humanitarian developers behind World of Warcraft have also discovered a way to bribe gamers into turning off their computers and going outside. If you log off for a few days, your character will be more 'rested' when you resume playing, a mode that temporarily speeds up your leveling.

Clive Thompson

Being Welsh means you sometimes get exposed to international football earlier. Again, that helps player development, speeds up their thought process in a different kind of environment.

Craig Bellamy

Perhaps genes did regulate the aging process. Perhaps different organisms had different life spans because a universal regulatory 'clock' was set to run at different speeds in different species.

Cynthia Kenyon

Studies of social games, puzzle games, and brain-training games have shown they have little effect on the brain despite often being marketed as improving memory and reaction speeds.

Daphne Bavelier

I remember going from rookie ball to A, to double A, then to triple A. At every level it seemed like the game was faster. The bigger the situation, the more the game speeds up. That's all mental. It messes people up.

Derek Jeter

Sometimes a script comes along that really makes you sit up and pay attention... 'Life at These Speeds' has an emotional intensity that really kicked me in the guts.

Douglas Booth

There's times when I'll be out in the middle of the track, standing in the curve, and I'll just laugh. 'What the heck am I doing right now? I'm sliding down the hill at crazy speeds and standing in freezing cold weather.'

Elana Meyers

When you make music, you're forming these invisible vibrations in the air into different shapes and consistencies and speeds in order to create music, and understanding how the math of that works just gives you more colors to paint with, and allows you to get to what you want quicker.
