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.
Perception plays a vital role in the diagnosis of bipolar illness. Symptoms are perceived through the categories of psychiatric medicine at a given moment in history, categories which are continually shifting and being named or renamed.
I just try to stuff my brain with everything that I can read on what is going on in science at a very high level, and sometimes I see connections of what might need to be done.
Sometimes I had to spend a whole day mixing a boiling mass with a heavy iron rod nearly as large as myself. I would be broken with fatigue at the day's end. Other days, on the contrary, the work would be a most minute and delicate fractional crystallization, in the effort to concentrate the radium.
Nearly every one of the genes that turns out to be a key player in cancer has a vital role in the normal physiology of an organism. The genes that enable our brains and blood cells to develop are implicated in cancer.
Anyone who thinks science is trying to make human life easier or more pleasant is utterly mistaken.
More than two decades after the birth of Louise Brown, and all the hysteria that surrounded her 'test tube' conception, we should know that institutions, not technologies, create dystopias. Artificially conceived children are everywhere, beloved by their parents, and they haven't radically altered our world.
