Physicist Quotes

It turns out that if you optimize the performance of a car and of an airplane, they are very far away in terms of mechanical features. So you can make a flying car. But they are not very good planes, and they are not very good cars.
Like immense time-binding discussions, genres allow ideas to be developed and traded, and for variations to be spun down through decades.
Like the ocean, land plants hold about three times as much carbon as the atmosphere. While oceans take many centuries to exchange this mass with the air, flora take only a few years.
Mathematics cannot handle physical quantities like density that literally go to infinity.
My brother Jim and I shared a womb without a view for nine months.
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.
Nostalgia is eternal for Americans. We are often displaced from our origins and carry anxious memories of that lost past. We fear losing our bearings.
Our moon was born too small to harbor life. It came from the collision of a Mars-sized world into the primordial Earth. From that colossal crunch spun a disk of rocks that condensed into a satellite.
Reared in rural southern Alabama, we enjoyed an idyllic Huck Finn boyhood. But education there was casual at best. Our mother and father were high school teachers and challenged the pervasive easy-going ignorance.

Star Trek's insight lay in the promise of going to the stars together, with well-defined stereotypes who could supply the emotional frame for the potentially jarring truths of these distant places.
Terraforming our moon will take many decades and vast abilities. Before we can begin, we'll have to master the resources of our solar system - especially transporting raw masses over interplanetary distances.
The common liberal orthodoxy that living close to the land leads to eco-awareness is historically naive, considering that Mesopotamia, northern Africa, and the Mayan civilization were ruined by people who had lived there quite a long while.
The earliest depiction of libertarian eugenics may have appeared in a science fiction novel, Robert Heinlein's 1942 tale 'Beyond This Horizon.'
The Matrix itself is not some external evil, but rather an outcome of our own error, our karmic payoff of past actions. Not merely illusion, it is an allusion to a founding myth of our culture.
The moon's closeness is a huge advantage: To make it habitable, we would first have to bombard it with water-ice comets, a tricky endeavor best attempted with the many resources waiting on and near Earth.
The people who built the space program - both Soviet and U.S. - were readers of science fiction.
The simplest way to remove carbon dioxide, the main greenhouse gas, is to grow plants - preferably trees, since they tie up more of the gas in cellulose, meaning it will not return to the air within a season or two. Plants build themselves out of air and water, taking only a tiny fraction of their mass from the soil.
