Pluto's orbit is so elongated that it crosses the orbit of another planet. Now that's... you've got no business doing that if you want to call yourself a planet. Come on, now! There's something especially transgressive about that.
Interpretation
Pluto's irregular orbit challenges its classification as a planet in our solar system.
Neil Degrasse Tyson comments on Pluto's unique and elongated orbit, which intersects with that of other celestial bodies. This unusual characteristic raises questions about the criteria for planetary status, suggesting that to be classified as a planet, one should adhere to certain predictable patterns in their orbit, emphasizing a broader understanding of the dynamics of our solar system.
In practice
In a lecture about planetary science, you could illustrate how Pluto's orbit challenges traditional classifications.
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.
The Soyuz craft weighs tons, and you're lying on the floor of it on your back. But the Russians do tell you, remember, before you land, stop talking so you don't bite your tongue off.
The fact that life evolved out of nearly nothing, some 10 billion years after the universe evolved out of literally nothing, is a fact so staggering that I would be mad to attempt words to do it justice.
It turns out your conscious mind - the part you think of as you - is really the smallest part of what’s happening in your brain, and usually the last one in line to find out any information.
If we're going to go farther from Earth, to Mars or somewhere else someday, we have to have a good understanding of the psychological impact on people. And not only psychologically, but how it affects their cognition. We're doing a lot of research on my cognitive abilities.
Radio has no future." "X-rays are clearly a hoax". "The aeroplane is scientifically impossible.
Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.
