The chances that your tombstone will read 'Killed by Asteroid' are about the same as they'd be for 'Killed in Airplane Crash.'
Interpretation
This quote highlights the improbability of dying from rare events, suggesting that fear of such occurrences is often irrational.
Neil Degrasse Tyson uses this quote to illustrate the statistical unlikeliness of dying from uncommon causes, such as being killed by an asteroid or in an airplane crash. By comparing these two rare events, he encourages us to focus on the more probable risks in life, suggesting that our worries may often be misallocated to unlikely scenarios instead of more pressing concerns.
In practice
During a speech about overcoming fear, you might quote Tyson to illustrate how we often fear the wrong things.
The problem is that many people operate on the assumption that NASA should go to Congress every year with hat in hand and justify it every year. Well, I see it as the greatest economic driver that there ever was. Economic drivers don't need justification.
The press still thinks [global warming] is controversial. So they find the 1% of the scientists and put them up as if they're 50% of the research results. You in the public would have no idea that this is basically a done deal and that we're on to other problems, because the journalists are trying to give it a 50/50 story. It's not a 50/50 story. It's not. Period.
As a scientist, I want to go to Mars and back to asteroids and the Moon because I'm a scientist. But I can tell you, I'm not so naive a scientist to think that the nation might not have geopolitical reasons for going into space.
In just one year, the expenditure of of the U.S.'s military budget is equivalent to the entire 50-year running budget of NASA combined.
One of my great laments is that education today seems to have... be less about passion and more about process, more about tactic or technique.
Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.
We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.
I can never look now at the Milky Way without wondering from which of those banked clouds of stars the emissaries are coming. If you will pardon so commonplace a simile, we have set off the fire alarm and have nothing to do but to wait. I do not think we will have to wait for long.
The image of Stephen Hawking - who has died aged 76 - in his motorised wheelchair, with head contorted slightly to one side and hands crossed over to work the controls, caught the public imagination as a true symbol of the triumph of mind over matter.
All you are is a bag of particles acting out the laws of physics. That to me is pretty clear.
But I hope that it will also be demonstrated soon that in my experiments in the West I was not merely beholding a vision, but had caught sight of a great and profound truth.
The scientist is not responsible for the laws of nature. It is his job to find out how these laws operate. It is the scientist's job to find the ways in which these laws can serve the human will. However, it is not the scientist's job to determine whether a hydrogen bomb should be constructed, whether it should be used, or how it should be used. This responsibility rests with the American people and with their chosen representatives.
