How do we get spacecraft out of orbit? Neil deGrasse Tyson and Chuck Nice break down everything you need to know about deorbiting spacecraft and safely reentering our atmosphere. How are we going to get the ISS out of orbit?
Learn about terminal velocity, escape velocity, and how aerobraking heat shields save fuel. We discuss issues with uncontrolled orbits and crashing into the Pacific Ocean. Plus, why did we let Casini burn up in Saturn’s atmosphere? How are we going to get the ISS out of orbit? Neil also shares his ideas about the new space race and China’s space station.

As someone who hated rote memorization, the multiplication table is 'fuzzy' around the mid 6's and 7's. So, I actually came to the correct answer at about the same moment Chuck did. I do think he missed a comedic opportunity to echo Neil's frustration, when Neil says "49 is twice 25."

Always great to see Neil using his office, at the Hayden Planitarium as a set . So many interesting books and artifacts just out of focus. Would be great if when filming from his office that Neil shares some info on the books on his shelves. Ideally, one title every time he post a video from his office, but even a Book of the Month would be great. Books are awesome, they don't need batteries and totally impervious to solar storms and any other forms of electromagnetic interference. Please share !👍👍👍

@@vanshamb If you actually study physics, you learn that K=1/2 mv² much earlier, but people who haven't studied physics have never heard of K=1/2 mv², they've only heard of E=mc², even if they never really understand what it means.

@@vanshamb ur not wrong; I think Neil was just going for the low hanging fruit that the common undereducated American would know, even if their understanding of it is closer to E = MC Hammer. The kinetic energy formula is precisely what engineers use for spacecraft kinetics. The kinetic energy formula is part of General Relativity, and in non-relativistic cases GR reduces to KE. The mass energy equivalency is what Special Relativity reduces to for speeds that are not a significant fraction of the speed of light. They're both parabolic equations that fall out of hyperbolic equations.

This video is why I don't do math in public... And kinda' not cool to both put Chuck on the spot like that and then shame him rather than just say something like "Not quite, I think it's 49" (or something similar) Lastly, Chuck, thanks for being so willing to share your struggle with depression - that's a very difficult thing to talk about, and, as you said: often a source of shame. I'm glad you found the help you needed and what worked for you!

@stevenqirkle 2 ай бұрын

I disagree. Unless you have a severe learning disability, I think it’s kind of shameful to not know your multiplication tables as an adult. I agree it’s not cool to shame people with disabilities, but in Chuck’s case I suspect it’s probably not a disability, but rather he just didn’t do his math homework in 3rd grade.

@a24396 2 ай бұрын

@@stevenqirkle I don't agree. Not everyone can recite multiplication tables for a variety of reasons, many having nothing to do with severe disability. Just like some people have bad spelling. That's not a moral failing either, however much you may want to judge people for that.

@@a24396 in a 10x10 multiplication table, there are 55 unique combinations to remember. Anyone can do it. It’s nowhere near as difficult as spelling, which has a much larger vocabulary as well as many homophones and irregularities. What other reasons are there besides not putting in the effort and/or learning disability?

@a24396 2 ай бұрын

@@stevenqirkle Incredulity is not an argument. Just because you can't imagine this doesn't mean it's not a real problem for people who are both not lazy and not profoundly disabled. I recommend you go to google and search for 'reasons people don't remember multiplication tables.' You might discover that human brains aren't just biological equivalents of calculators/computers and not everyone is 'wired' the same. In the same way that some people 'get' spelling and others don't, some people 'get' mathematics and others don't. Or... Continue to disbelieve anything you don't understand or for which you haven't figured out an answer... Whatever makes you happy!

A helpful analogy for visualizing an object entering Earth's atmosphere is to envision yourself in a speeding boat, seated at the edge, with your hands skimming the water. The sensation of the turbulent fluid rushing past your hands, potentially causing harm, mirrors the experience of an object encountering Earth's atmosphere.
