I used to measure the skies, now I measure the shadows of Earth. Although my mind was sky-bound, the shadow of my body lies here. [ ]
Even with all our technology and the inventions that make modern life so much easier than it once was, it takes just one big natural disaster to wipe all that away and remind us that, here on Earth, we're still at the mercy of nature.
Darwin's theory of evolution is a framework by which we understand the diversity of life on Earth. But there is no equation sitting there in Darwin's 'Origin of Species' that you apply and say, 'What is this species going to look like in 100 years or...
I'm constantly claimed by atheists. I find this intriguing. In fact, on my Wiki page - I didn't create the Wiki page, others did, and I'm flattered that people cared enough about my life to assemble it - and it said, 'Neil deGrasse is an atheist.'
What happens when you take a lion out of the safari and try to take him to your place of residence and make him a house pet? It ain't going to happen. That's the type of person that I am. I'm that lion.
I have this pet thing about how global communications are moving so fast now, throwing information at you, making everything available to you, and yet I feel it's leaving us more and more isolated.
When one studies the properties of atoms, one found that the reality is far stranger than anybody would have invented in the form of fiction. Particles really do have the possibility of, in some sense, being in more than one place at one time.
If I were not a writer, I would spend more time doing the things that I am already doing, which include doing research in physics, teaching, and running a nonprofit organization with a mission to empower women in Cambodia.
Standing at my door, I heard the discharge of a gun, and in four or five seconds of time, after the discharge, the small shot came rattling about me, one or two of which struck the house; which plainly demonstrates that the velocity of sound is great...
You know that I write slowly. This is chiefly because I am never satisfied until I have said as much as possible in a few words, and writing briefly takes far more time than writing at length.
It is true that from a behavioral economics perspective we are fallible, easily confused, not that smart, and often irrational. We are more like Homer Simpson than Superman. So from this perspective it is rather depressing. But at the same time there...
Just because you see pictures of glaciers falling into the ocean doesn't mean anything bad is happening. This is something that happens all the time. It's part of the natural cycle of things. We know from measurements that glaciers have been melting ...
There are things that I would say that you could call an instant of time; or better, a now. As we live we seem to move through a succession of instants of time, nows, and the question is, what are they? There are where everything in the universe is a...
Technologies that may be realized in centuries or millennium include: warp drive, traveling faster than the speed of light, parallel universes; are there other parallel dimensions and parallel realities? Time travel that we mentioned and going to the...
People get cranky when you burst their bubble. Over time, advances in astronomy have relentlessly reinforced the utter insignificance of Earth on a celestial scale. Fortunately, political and religious leaders stopped barbecuing astronomers for sayin...
The universe is hilarious! Like, Venus is 900 degrees. I could tell you it melts lead. But that's not as fun as saying, 'You can cook a pizza on the windowsill in nine seconds.' And next time my fans eat pizza, they're thinking of Venus!
Clearly, enriching the cosmos with heavy elements takes a while. So there's inevitably an interval between the sterile aftermath of the Big Bang and a time when the cosmic chemistry set had enough ingredients to make rocky planets (and squishy biolog...
We are not angels, we are merely sophisticated apes. Yet we feel like angels trapped inside the bodies of beasts, craving transcendence and all the time trying to spread our wings and fly off, and it's really a very odd predicament to be in, if you t...
While human space travel is daunting, machines - with their indefinitely long lifetimes - could travel the galaxy. It might make little difference to them that bridging the distance from one star to the next could take hundreds of thousands of years ...
But Dr. Smith says, and I believe it to be a true state of the case, that he himself gave a course of Lectures in Natural Philosophy, during the same winter, and that the money raised by them was also applied towards paying for the Orrery.
While I have always thought that the motivation for looking for E.T. was both self-evident and patently worthy, it's possible that I'm a victim of my own job description. Others don't inevitably agree. Some will opine that there are better ways to sp...
