What we see today is an American economy that has boomed because of policies and developments of the 1950s and '60s: the interstate-highway system, massive funding for science and technology, a public-education system that was the envy of the world and generous immigration policies.

All the mathematical sciences are founded on relations between physical laws and laws of numbers, so that the aim of exact science is to reduce the problems of nature to the determination of quantities by operations with numbers.

As scientists, we step on the shoulders of science, building on the work that has come before us - aiming to inspire a new generation of young scientists to continue once we are gone.

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration.

The Connecticut Center for Science and Exploration will be a building that will connect the excitement of science to the surrounding streets, river and highway. These forms are ambitious and dynamic. They appear to reach out beyond their physical limits.

It was the late Dr. Mahendra Lal Sircar who, by founding the Indian Association for the Cultivation of Science, made it possible for the scientific aspirations of my early years to continue burning brightly.

I would not hesitate to say I was addicted to the Internet in the first two years. It can be addictive, and things not taken in moderation have negative effects. But the alarmism around 'Facebook is changing our brains' strikes me as a kind of historical trick. Because we now know from brain science that everything changes our brains.

Science has taught us, against all intuition, that apparently solid things like crystals and rocks are really almost entirely composed of empty space. And the familiar illustration is the nucleus of an atom is a fly in the middle of a sports stadium, and the next atom is in the next sports stadium.

Science fiction and fantasy is a kind of literature that embodies the highest aspirations of the human race.

If co-operation, is thus the lifeblood of science and technology, it is similarly vital to society as a whole.

The work of science is to substitute facts for appearances, and demonstrations for impressions.

The biggest benefit of Apollo was the inspiration it gave to a growing generation to get into science and aerospace.

A successful society is characterized by a rising living standard for its population, increasing investment in factories and basic infrastructure, and the generation of additional surplus, which is invested in generating new discoveries in science and technology.

A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.

It's sad, the lottery. Good projects get funded by it, but there's an air of desperation about it.

Our generation, unfortunately, is stuck to our phones - and, like, Twitter - constantly, which I have no problem with. I'd say we're not describing the children of America or anything like that, but there is something to take from it: It is kind of sad how we can't go thirty minutes without checking our phone.

I take my inspiration for the song writing from little experiences, not even if I've experienced them myself but say if something has made me sad, I will use that emotion. I just use everyday life and write about it.

It makes me sad that corporations and media and Hollywood conspire to make people feel terrible about their bodies from the second they wake up, so I sort of try to subversively undercut that.

When I did the film Generations, in which the character died, I felt like a guest for the first time. That made me very sad.

My father comes from a generation of film that actors my age don't even know about, which is really sad.

Because the sad fact is that the Enron Corporation and others manipulated with unfortunately great effect the energy market in the West Coast starting in 2000.

From inside where I live, I feel like I just perceive events in a certain rational way. I often find it sad or poignant, and it may not make me laugh a bit. But I don't mind inventing a portrait that allows others to laugh if that's what they want to do.

It is a historical error for those who were not there to just refer to August 28th as 'I Have a Dream' speech day. That is a real disservice to those who were there. It was a sad day. It was not a celebration environment.

I can't speak for everybody. But I will say that for me, when I've been depressed - and I get depressed. I have irrational bouts of anxiety. I have random FedEx deliveries of despondency. Just like, 'I didn't order this. Oh, well, keep the PJs on, cancel everything you're doing today. It's time to take a sad shower.'
