Work from home will relieve the pressure on urban infrastructure and land, which can be released for mass housing or public transport, and critical lung space.

A golf course is the epitome of all that is purely transitory in the universe; a space not to dwell in, but to get over as quickly as possible.

As always, space remains an unforgiving frontier, and the skies overhead will surely present obstacles and setbacks that must be overcome. But hard challenges demand fresh approaches, and I'm optimistic that Stratolaunch will yield transformative benefits - not only for scientists and space entrepreneurs, but for all of us.

Sending greeting cards to aliens is hardly a new idea. In 2005, Craigslist solicited messages for broadcast to space by a transmitter in Florida, and in 2008, NASA beamed a Beatles song to the North Star (Polaris), on the assumption that any putative Polarians would appreciate the Fab Four's 1960s-genre compositions.

We have one planet in our solar system that's habitable, and that's the Earth, and space travel can transform things back here for the better. First of all, by just having people go to space and look back on this fragile planet we live on. People have come back transformed and have done fantastic things.

Most of our history in space has been communicated in terms of action - what people do, a chronological list of events which have transpired - as opposed to the human experience of having done those things.

If we drive down the cost of transportation in space, we can do great things.

If you say, I'm for equal pay, that's a reform. But if you say. I'm a feminist, that's a transformation of society.

Society is becoming less and less transparent. People no longer know where decisions that substantially affect their lives are taken, nor by whom, nor how.

Society doesn't tell you that you can be trans.

There is a very intense culture of secrecy in Britain that hasn't yet been dismantled. What passes for transparency here would serve any secret society well.

The roles that men and women play are no longer the standard traditional roles of way back when but are those of two very individual people living their lives. I think it's been a hard transition in society - just take a look at the divorce rate - to figure out what that means now. How do you resolve that?

The women's movement was always going to work in two parts. With one part, we'd break open the doors that were closed to women, and with the other part, we'd walk through, transforming society for men and women. Turns out it was a lot easier to open the doors.

Every genuine boy is a rebel and an anarch. If he were allowed to develop according to his own instincts, his own inclinations, society would undergo such a radical transformation as to make the adult revolutionary cower and cringe.

The main ingredient of the first quantum revolution, wave-particle duality, has led to inventions such as the transistor and the laser that are at the root of the information society.

Black Lives Matter is not just concerned with what happens in policing. The disregard, the disrespect, and the lack of dignity for black life transcends through the fabric of our society.

Philanthropy is involved with basic innovations that transform society, not simply maintaining the status quo or filling basic social needs that were formerly the province of the public sector.

The Internet: transforming society and shaping the future through chat.

In Delhi, where I grew up, commerce is brusque. You don't ask each other how your day has been. You might not even smile. I'm not saying this is ideal - it's how it is. You're tied together by a transaction. The customer doesn't tremble before complaining about how cold his food is.

Scarlett Johansson has a smile she tries to suppress in every movie she makes. She's been trying to keep a straight face since she appeared with Bill Murray 11 years ago in her breakthrough, 'Lost in Translation.'

In Israel, a land lacking in natural resources, we learned to appreciate our greatest national advantage: our minds. Through creativity and innovation, we transformed barren deserts into flourishing fields and pioneered new frontiers in science and technology.

Transhumanism is the ethics and science of using things like biological and genetic engineering to transform our bodies and make us a more powerful species.

Science tells us we need to keep the majority of fossil fuels in the ground, and that we must urgently invest in renewable energy, and other alternative industries. Doing so would create millions of jobs, ensure a fair transition for fossil fuel workers into new industries, and avert the most catastrophic climate breakdown.

The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species.
