When someone says that information is on a “need to know” basis, your mind might automatically think that the information is secretive, dangerous, etc. But, there’s another type of “need to know” information that involves different “levels” of information.
On this StarTalk explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice are exploring these different “levels” of information. We discuss why, in certain circumstances, an idea is better than the details. To understand these levels of information, we explore the Earth’s orbit around the Sun. You’ll learn why you can say the Earth goes in a circle around the Sun and be “correct” even though it’s actually an elliptical orbit. And you can say it’s an elliptical orbit even though it’s actually a loop-de-loop!
Find out how Earth’s tilt influences our seasons. You’ll also find out about the “libration” of the Moon or as Chuck calls it “Moon twerking.” And, we discuss Earth’s precession around the Sun. Lastly, Neil uses the size of the Sun as another example of understanding different levels of information. All that, plus, we explore why the scientific method allows for the possibilities of change.

I have Asperger's. In high-school I almost failed because I couldn't memorize things I didn't understand, notably maths. When I got to college and they started going into _why_ the derivative of sine is cosine, suddenly my grades shot way up. With no additional effort on my part. It was like I was sailing against the wind and then suddenly the wind turned 180° and everything came naturally. We don't all process information the same way, and unfortunately they can't afford to sort kids out according to how they work. We have to bear with it and find our own way.

Public schools are not in interested in teaching students. They are interested in job security. I have learned more SINCE graduating high school than I ever did in all the time in grades K-12.

I agree that an overhaul would be in order and it is sad indeed that kids walk out of school without much useful knowledge. I consider myself fortunate for actually having learned many of these things in school; but, nevertheless, the way Mr. Tyson presents them makes me want to listen; sometimes for the sake of learning more, sometimes... just for the fun of it. He is really gifted when it comes to bringing complicated things down to Earth. I wish more teachers were like him; the school system would be much better. And the dialogue between him and Chuck is the icing on the cake.

I have a child in 8th grade and it makes me sad when I share what I feel should be knowledge that should've been taught to them already, like things about our solar system for example, is met with shock and awe.

This is a great video. I had a teacher once tell me that ‘education is a series of decreasing lies.’ This is a perfect example of that. The orbit of the Earth is a circle. Well actually, Earth’s orbit is not a circle but an ellipse. Well actually, the Earth’s orbit is not entirely an ellipse, but a wobbling, processing ellipse.....

@1radkill420 2 года назад

and actually its a circle with 3% variance in diameter. So the original visuals of the orbits are more correct then current visuals. whats real anymore? no wonder people believe flat earth is possible.

@MunyuShizumi Год назад

@@1radkill420 "Circle with 3% variance in diameter" is literally an ellipse by definition, how is that another "ackchyually"? Visualizations are intentionally exaggerated so it would be clear that it's _not_ a circle, otherwise we wouldn't be able to perceive the 3% variance. Also, it would only appear as an almost-circle when viewed from the orbital/ecliptic pole. When viewed from any lower angle, it'll look more and more like the seemingly exaggerated ellipse seen in most illustrations, i.e. a lot of those can be 100% realistic proportionally and only have apparently higher eccentricity due to perspective causing a bit of an optical illusion.

@stevemotocrayz2892 Год назад

Thomas...it is actually, correctly called "precession" , (not PRO-cession), and has a complicated definition...and giving you that definition here would probably put you off a bit...which is the point of the whole vidéo..!! A simple definition is: A complex motion executed by a rotating body subjected to outside torquing force(s).

@stevenbrucci Год назад

@@1radkill420 Reading your post, i imagine that what puts people off science is that the universe--and every little part OF it--is almost infinitely complex. That includes the realm of human economics. Since the elite have had better access to computing power ever since WWII, the great populace have gradually lost economic power. So, it's understandable that there is this growing desire for simplicity and accompanying distrust of those who better understand complex systems. But to refrain from facing that common human challenge of learning about and better-understanding the world simply plays into the hands of those elite who are becoming more and more used to the availability of serfs and slaves who now don't even WANT to understand reality or accept that it is-- and always HAS been--complex.

Stars twinkle because the light you see from them is the light that they themselves emit - think of it like a giant nuclear reactor pulsating with enormous waves of energy in the form of light. Planets on the other hand (and the Moon) do not twinkle - that's because they are only reflecting the light cast on them by the Sun - that's how you can easily differentiate a star from a planet on the night sky (feel free to use it on a date). If you look at the Sun through sufficient shielding you can even observe this phenomenon without looking at stars - it also "twinkles" pulsating with the emitted energy.

I have known who Neil DeGrasse Tyspn is for a LONG time. But I never really watched or heard more than short snippet's of subjects he expressed. But I saw a video of his show up where he talked about algae on a pond doubling it's size each day. When he got to the question he posed to the person he was talking to, my mind immediately popped to "Tomorrow, the next day.". Yet when I asked other people they did the same thing the other person in the video did by guessing something like "I dunno, a month?". In the end I started watching more videos of his talking about different subjects and am surprised how many he touches on where I find him saying something I often express on the same subject. It's left me with one thought. I'm just 1 person in the almost 8 billion people on Earth but so is Neil. He just happens to be 1 I think would be awesome to have as a friend.

It can go the other way, too. I had a boss years ago that attempted to teach a co-worker and I programming in just a couple sessions over Skype. He was always trying to jump way ahead of the current material. He was very impatient, getting mad that neither of us were "getting it" on his timetable. I tried to explain that it was like handing a cave man an etch--a-sketch for a few hours and then saying, "Ok, well here's an iPad, write up an email with merge fields and email these 200 clients".

@alexzandermorgan9356 3 года назад

Neil is such a great educator because you can literally see and hear how excited he gets about all sciences. I believe this to be a huge issue in schools across the globe, many teachers do not show their excitement about what they teach when that excitement is important to help motivate kids to learn what is being taught. I’m very curious as to why there aren’t more teachers like Neil, I have some hypothesis but I haven’t found a complete answer yet.

@adityamishra7711 3 года назад

You consider sharing me those hyposthese ? Dont worry, me myself had been frustrated with this similar kind of problem since 5 years

@MrKenpokarate Год назад

I think normal educators aren’t excited is the problem. Occasionally you get a fantastic educator who really understands the material and it’s exciting. There are educators out there that believe the earth is really 6000 years old and that the Bible is scientifically accurate, so of course they aren’t excited about the material they disagree with it.

@theduder2617 10 месяцев назад

The students themselves have a responsibility which continues to not be addressed. One does NOT need excited educators in their lives in order to educate while understanding the education provided. Many who fail out of school, failed out due to their own laziness and lack of self motivation. And proof exists within their school records. Yes, there are those who do not realize they are bored with the material because it is basically a repeat of the previous year's studies. They never realize that advancing forward a grade or three can make the very difference needed to obtain a previously non-possessed excitement and motivation towards learning. But for the most part, school failures have much more to do with the individual than it does the educator(s). ESPECIALLY TODAY! 97% of school failures and drop-outs failed and/or dropped out because they had no interest in learning. And they learned that laziness from mommy and daddy who were themselves, grade school drop-outs. Continuing to worship a person who on live TV used the words "I can declassify them by thinking about it", was NOT a result of bad educators. That is only the end result of a direct refusal to educate, nothing else. Students, with parents or not, are as responsible for their education as are the educators. They have internet at their fingers NON-STOP 24 hours a day. What do they choose to use the internet for? Surely NOT for the original intended purpose of the internet back when it was first proposed, on through to its design and introduction. They could be excited enough to learn if they desired to learn. But that would fly directly in the face of chosen delusional fantasy for most today under the age of 45. Not to mention their desire for laziness at every turn.

NdGT has redefined both astrophysics and science in general. He is one of the most important scientists of the 21st century because of this. Unlike important scientists who are important for their discoveries or creations, he is important for the way he has explained it ALL. His energy and passion about science (and seeking-knowledge in general) has permeated into pop culture which will bring 1,000s of additional kids into science based fields, which will inevitably create a better 21st century for the world through new scientific discoveries and inventions. I am extremely grateful to NdGT for that. Finally there is a scientist (more so then Sagan) who can be and does belong on posters on children's walls.

When teaching, we want to go from what is known to what is unknown. Start with the circle, but ... then go to the ellipse, but ... throw in the Earth-Moon system motion, but ... get the procession in there. It is just that at each step, there is more that is known and the next step reveals more that was previously unknown.

@cursedwolf1539 3 года назад

So earth's orbit is a 97% circle?

@joshuawoodford7525 3 года назад

Essentially, but the word circle by definition is perfect, so you wouldn't use an identifier before it. For example you wouldn't ask me how round a circle is, but you may with an ellipse. I always thought it was funny when I would hear someone say perfectly round but I've come to understand it does add value when describing things other than technical shape. Anyway super hilarious 🤣😁😉

@0LoneTech 3 года назад

It's more like a ±1.7% inaccurate circle.

@gnarthdarkanen7464 3 года назад

We NEED a "technical term" for "imperfect circle" as opposed to "ellipse"... It would help a lot of students get a better picture for the "graphical solution" in these kinds of problems. The Earth progresses through a 3% imperfect circle... BUT when you say "ellipse" there's the overbearing distraction of an oval or "egg shape" so students don't just get it... We could understand it SO much easier if it was just always taught as "The earth travels around an imperfect circle." instead... Right? I mean, you "get" that a circle is perfectly round... You can also get that "If it's not perfectly round, technically it's not a true circle."... BUT it gets complicated quickly when you use terms like "ellipse" or "elliptical" and "oval". At 3% variation, it's still relatively circular... just not a perfect circle... I'd suggest "imperfect circle" is an improvement upon either just a circle or elliptical path. ;o)

"need to know" is more military slang. Capacity of knowledge may be right if you think it "in a spoonful". If the person knows nothing, you can give only the idea. Once the person digested the first raw idea, you can give another bite of info. And so on.

Neil is a great role model for me as a science teacher. I am also impressed often with Chuck's knowledge too, compared to what I would think an average comedian would know. He likes to pretend he is dumb sometimes for comedic effect, but he usually has knowledge of the subject to participate in discussion.
