Scientist Quotes

Ultimately, the only wealth that can sustain any community, economy or nation is derived from the photosynthetic process - green plants growing on regenerating soil.
We need to manage holistically, embracing all of our science and traditional knowledge - all sources of knowledge. We can do that from the household to government to international relations.
Energy-saving technologies keep improving faster than they're applied, so efficiency is an ever larger and cheaper resource.
Fire made us human, fossil fuels made us modern, but now we need a new fire that makes us safe, secure, healthy and durable.
I am a man without a furnace. My windows are insulated by 19 sheets of glass which cost less than installing a heating system.
I'm a practitioner of elegant frugality. I don't feel comfortable telling other people what to do, so I just try and lead by example.
I'm not an environmentalist. I'm a cultural repairman. It's all about efficient and restorative use of resources to make the world secure, prosperous and life-sustaining.
Public discourse about climate change has resulted in the erroneous idea that it's all about cost, burden and sacrifice. If the math was correct, everyone would see it's about profit, jobs and competitive advantage.
Better degrees don't automatically translate into better skills and better jobs and better lives.
Despite the characterization of some that teaching is an easy job, with short hours and summers off, the fact is that successful, dedicated teachers in the U.S. work long hours for little pay and, in many cases, insufficient support from their leadership.

An ordinary black hole is thought to be the end state of a really massive star's life.
As an astronomer, I get to ignore the details of the things that we don't understand. There's a lot of work that we can do on scales that we do understand, and there is actually a finite size that I can associate with a super massive black hole.
Astronomers are obsessed with building larger and larger telescopes. There are two promises that we make with bigger telescopes: that they can see fainter things and that they see more detail. But it's been really hard to follow through on that second promise because of atmospheric distortion.
Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics quite right.
Fortunately, most things around the supermassive black hole are just going to go around it. They're going to orbit it. They don't actually get sucked in.
Gravity wins over all other known forces.
How do you observe something you can't see? This is the basic question of somebody who's interested in finding and studying black holes. Because black holes are objects whose pull of gravity is so intense that nothing can escape it, not even light, so you can't see it directly.
