Scientists are slowly waking up to an inconvenient truth - the universe looks suspiciously like a fix. The issue concerns the very laws of nature themselves.

There are sadistic scientists who hurry to hunt down errors instead of establishing the truth.

The only technology that can 'see' beneath the ground is radar imagery. But satellite imagery also allows scientists to map short- and long-term changes to the Earth's surface. Buried archaeological remains affect the overlying vegetation, soils and even water in different ways, depending on the landscapes you're examining.

I remember being in a history lesson and saying to my teacher, 'How come you never talk about black scientists and inventors and pioneers?' And she looked at me and said, 'Because there aren't any.'

NASA space scientists have been studying giraffe skin so they can apply what they learn from it to the construction of spacesuits.

Consciousness, rather than being an epiphenomenon of matter, is actually the source of matter. It differentiates into space time, energy, information, and matter. Even though this view is an ancient view, an ancient world view, it is now finding some resonance amongst a few scientists.

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.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

I am sorry to say that there is too much point to the wisecrack that life is extinct on other planets because their scientists were more advanced than ours.

What we want is scientists who don't become part of the policy discussion: All they do is produce science. If someone becomes an advocate, then I won't pay as much attention to their science.

I think that all research scientists think of themselves as belonging to a grand tradition, building on work that has been worked on since the very beginning of science itself. Whereas I'm not sure writers think of themselves in the same way.

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.

Science fiction is no more written for scientists that ghost stories are written for ghosts.

My feeling is that science is virtually an unexplored ground. It's very visible - more so all the time - but there's no fiction that tells us how scientists think, and they really don't think the way that other people do.

We didn't set out to be educators or even scientists, and we don't purport that what we do is real science but we're demonstrating a methodology by which one can engage and satisfy your curiosity.

Science fiction rarely is about scientists doing real science, in its slowness, its vagueness, the sort of tedious quality of getting out there and digging amongst rocks and then trying to convince people that what you're seeing justifies the conclusions you're making.

I also think we need to maintain distinctions - the doctrine of creation is different from a scientific cosmology, and we should resist the temptation, which sometimes scientists give in to, to try to assimilate the concepts of theology to the concepts of science.

Many of the mainstream agricultural scientists, especially at the agricultural schools, but at all of our major universities, are tied into all sorts of contractual relationships and consulting relationships with the life science companies.

I find the attempt to find things out, which scientists are possessed by, to be as human as breathing, or feeding, or sex. And so the science has to be in the novels as science and not just as metaphors.

Some dreamers demand that scientists only discover things that can be used for good.

Luckily, unreasonable expectations go hand in hand with naive young scientists. The more naive the better - otherwise we would never have the audacity to try and build a 22,000-mile-high space elevator or some sprawling underwater hotel.

When I find myself in the company of scientists, I feel like a shabby curate who has strayed by mistake into a room full of dukes.

Facts are the air of scientists. Without them you can never fly.

Scientists worldwide agree that the reduction needed to stabilize the climate is actually more like 80 percent.
