I grew up in the 1960s in Memphis, and my father was a member of the American Civil Liberties Union. I was born three years before Martin Luther King was killed, and I think that history of civil action was something that I had in my blood.
Europe and North America, we are told, are less dependent on energy-intensive heavy industry than in the 1960s and 1970s. It seems we squeeze more GDP out of a barrel of oil than in those benighted days.
The tactics we were able to use in the 1960s, 1970s - let's have a campaign, mobilize everybody and, therefore, social pressure - stop littering, or stop spitting, or be courteous to one another: I am not sure that kind of approach will work anymore.
I was a kid at the end of the 1960s and in the early 1970s, so a lot of things changed. You had pop music coming up, with David Bowie, you had new television programmes and all these things. I was fascinated.
Introduced in the 1960s, multitasking is an engineering strategy for making computers more efficient. Human beings are the slowest elements in a system.
In the 1960s, and stretching back to the 1930s, it was felt by many economists that easy money is a reliable way to increase employment.
If you spend any time in Washington you'll find nerds. What happens is most of them sublimate their fixations with comics, or baseball cards, or 1960s British comedies to policy minutiae and political arcana. But, like Christians in ancient Rome, you can still spot them if you know the signals.
My parents were active in the anti-war movement in the 1960s, so I grew up with a tradition of civic activism around our dinner table and going to different marches for different causes.
I went through college in the 1960s without having any idea that I was going to have to make a living. When I graduated in 1968 it was quite a shock to find out that there was a world out there and that it wasn't going to support me.
When a black man is stopped by a cop for no apparent reason, that is covert racism. When a black woman shops in a fancy store and is followed by security guards, that is covert racism. It is more subtle than 1960s racism, but it is still racism.
I think I had a fur coat that someone bought me from Portobello Market back in the 1960s, but I think as soon as you think about it, what it is you're wearing, make that connection, then you realise it's just not right. I don't lecture people about it, but it's not something I'd ever wear.
After 25 quarters of so-called recovery under Obama, it has increased a total of only 14.3 percent. Compare this to earlier periods. After the JFK tax cuts of the early 1960s, the economy grew in total by roughly 40 percent. After the Reagan tax cuts of the 1980s, the economy grew by a total of 34 percent.
A black man of my generation born in the late 1960s is more than twice as likely to go to prison in his lifetime then a black man of my father's generation. I was born after the Voting Rights Act, after the Civil Rights Act, after the Fair Housing Act.
A war still rages over the legacy of the 1960s.
It seems like the record industry made so much crazy money in the 1960s that everyone wanted to get in on it. Now it's just become very corporate. So all of these people who despise music end up being in charge.
The 1960s was a heroic age in the history of the art of communication - the audacious movers and shakers of those times bear no resemblance to the cast of characters in 'Mad Men.'
I built up a knowledge of 1960s and '70s British films because my dad used to work nights, and I'd sit up with my mum and watch films - 'How I Won the War' and the films of Richard Lester, Karel Reisz and John Schlesinger.
It was in the early 1960s that my late revered teacher, Professor Abraham Joshua Heschel, became the first major Jewish theologian in America to enter into dialogue with Christian theologians on a high theological level.
New developments in weapon systems during the 1950s and early 1960s created a situation that was most dangerous, and even conducive to accidental war.
America before the 1960s was a pretty innocent place. We were the Lone Ranger galloping off to the rescue of the needy and the oppressed of the world, and we could get things done.
Some of us stay married because we're in competition with our divorcing 1960s and 1970s parents, who made such a hash of it. What looks appealing to us now, in an increasingly frenetic, digital world, is the 1950s marriage.
The dreams of the 1960s began to disappear in the 1970s. The economy collapsed, and so did the optimism of the Metabolists.
I had the good fortune to be raised in the 1940s and the 1950s. As I entered business in the late 1950s and 1960s, America was just coming into its own as a great industrial power. It allowed young entrepreneurs to start their engines, to start their businesses, to borrow a little money and to leverage what they had.
Many African smallholder farmers did not share in the 'green revolution' productivity gains driven by modern seeds and techniques, irrigation, and greater fertilizer use in Asia and Latin America in the 1960s.
Sometimes a malfunctioning test setup actually gives the tested system a chance to show what it can do in an unrehearsed emergency. During a test of an Apollo escape system in the 1960s, the escape system successfully got the capsule clear of a malfunctioning test rocket.
