Yep, with such people like Diana and Green brothers, we won't need school teachers anymore in ten years time max.

@@michaelcrockis7679 this video is ten minutes. When Diana can get kids to learn for 40 hours a week, THEN you can argue she is competing with school teachers.

​@@seededsoul I agree with you easily if we are talking about really good teachers. 1%, maybe 5% of all the teachers. Meanwhile, she is already competing. I've read far too many comments on this channel saying "I love physics because of you'" and enough comments on the CrashCourse channel saying "I've watched your videos and passed the test. Why all the teachers are not like you, John". One of the few things I know about children and learning is for them to really learn and (!) remember they must be interested and engaged. Not to be locked up in the room with some low paid megalomaniac for forty hours a week. Guys like she are not eliminating teachers, they are raising the plank. Because, you know, she is pretty, she is smart, she is likable, she talks clearly, she is fashionable, she is friendly. Unlike too many of the school teachers. She attracts attention and using this leverage embeds information in children's minds. Far more effective than school employees do. This 10 minutes of hers gave the audience more than 40 minutes in class. It is just the future. Tech changes things. The situation is very similar to the one in the music industry. We don't need to go to the local pub where drunk musicians play on bad instruments, to listen to a new song as we did 100 years ago. We had no choice then. Now we listen to the best musicians in the country and in the world in Hi-Fi quality in the comfort of our homes or better to say everywhere we wish to since we have portable devices. Education is not so different.

Well, an artificial magnetosphere is almost possible. It's just a big solar powered electromagnet stationed at the Sun-Mars L1 point. Doing this would keep the solar wind from stripping the atmosphere away from Mars and internal outgassing would improve the situation. Exactly how _much_ it would improve is up for debate.

I ahve always wondered why scientists believe the core is made of iron nickle alloy other metals as well. When we know for fact gravity( what ever it may be Higgs, muons, all that other boring quantum stuff (jk)) is partial and it prefers to "pull harder on metals such as lead gold. Tell me why It is theorized as it currently is please and thanks. I do.not believe we know even a tiny fraction of what we "call fact or treat as fact in majority cases. Dna on a quantum level as a quick example. Science believed majority of dna was junk. We just recently proved muons exist but Still don't understand gravity a fundamental of life since creation. Yet we understand the repercussions good or bad of altering the building blocks of people...I'm not buying it.

@@cavelvlan25 i think i can answer your question actually but a couple of notes: first, gravity pulls on everything equally and secondly, higgs bosons and muons are particles derived from ideas in quantum theory not relativity, which are **very** different fields of study. you cant say anything about the effects of gravity on things so small. to answer your original question. as far as i know, astronomers figure out the composition of planets by a using a combination of observation and some educated guessing. tracking the movement of something they put in orbit of the planet gives ideas of the densities of each layer (even the core). another way is tracking the earthquakes on the surface, we give similar indicators. i learned in my physics class (i'm a high school senior btw) that some scientists do something called spectroscopy, which uses light to decipher the chemical composition of planets and stars, which i think is cool. so yeah that's how they know

@@pola_behr Your answer shows they/you actually don't have the answer . Particle physicist do claim that gravity effects some particles differently than others. It either doesnt pull on everything equally or some things are immune to gravity. Relativity and quantum mechanics are as different as they are similiar as everything is relevant. Speculation no matter how informed is just thay Speculation. A for effort yet none of this is fact.

It's wild how important our moon is and how atypically big it is. Earth is super special.

I think she was inferring that our moon has a much more significant role in our orbit than Mar's tiny(non-consequential) moons, I in fact, many scientist think of the our Earth-Moon system as a "dual planet" because are moon is so large (in comparison to the Earth), and has such a large stabilizing effect on the Terran rotation and orbit.

@@pastresmalin34 Definitely. I mean, it's the size of a Ganymedan moon ffs, and Earth ain't Jupiter. Besides, I really think we need a new word for captured asteroids to differentiate them from natural spherical moons like we have one for "dwarf planets". Maybe "dwarf moons", or "asteroidal satellites"? Lol there's probably much better names, but an Europa, Ganymede, Enceladus or Titan which have atmosphere (the last one even thicker than Earth's...) and may even harbour life are something completely different from Phobos or the 70-something rocks orbiting Jupiter besides the 4 Ganymedan giants...

I've heard it said that a sign of true intelligence is the ability to explain complex subjects in a way that even a small child can understand. This is because it shows a deep understanding of the topic. It's also a wise thing to do.

@@AwwwThatsMintocs Yes, that has also been my experience in life. There is something to be said for pedagogical skill as well, but people who don't turoughly understand a subject don't tend to be capable of explaining it in a simple, easy to understand way no matter how good a teacher they are. And there are people who are very good at what they do and obviously have a deep understanding of the field they are working with but struggle to explain the simplest aspect of it. There are many factors involved, for sure. But as a quick and quotable generalization i think you statement rings true :) Nuno, and Dianna herself, appear to be have all of these qualities.

Certain amounts of radiation? Try that it repels ZERO amounts of radiation.

@@georgearnold841 I'm seeing many articles where the wording about the radiation levels just say something like, "the surface of Mars is exposed to much higher levels of radiation than Earth" to which I infer that the thin atmosphere does offer some protection, even in the absence of a magnetic field and then there is differentiating how much radiation is repelled by electromagnetic fields alone. I'm reading up on the Mars Odyssey mission and results. I have no background in this area and was not speaking as an authority in any sense.

@@seaninness334 the 1% as thick atmosphere doesn’t do much for radiation protection as you are thinking. Mars’ essentially gets hit with the same amount of radiation as earth, just minus the diffusing effect from orbiting a bit further out. It’s a very dangerous amount. The “higher amounts than earth” description is just a short and simple way for journalists to relate the added danger, without going into technical terms most readers would have no reference for. Also, they don’t want to get into the widely varying levels, and possibly killing peoples dreams for manned Mars exploration & later colonization. Imagine writing an article about Curiosity or Elon’s plan for a colonization, and telling people a solar storm could mean the astronauts aren’t not coming home. The Elon Fanboys especially would be arguing against scientific fact with “he’s going to make an artificial magnetosphere before we go there.” (Something I’ve seen happen on other videos about Mars)

@@cjwrench07 I agree that the hype glosses over the blunt facts and that's what I'm trying to get at. Most of the articles in the popular media that I was reading became oddly vague in their descriptions. It's like the meme, "Your chances of being murdered by a cow are extremely low, but it's never 100% unlikely". I've worked mostly in the entertainment industry and films like The Martian (or Andy Weir's novels in general) make it seem possible with only a dash of actual science related to issues of survival and travel. So I would prefer the blunt data, even if it is simplified for us outsiders. George Arnold was just a tad condescending above. Anyway, I appreciate your POV and... all hail Cthulu, hehe

There are solutions for that. See futurist Isaac Arthur's YT channel. He is awesome. One of the easiest solutions we could do with today's technology is an array of magnetic satellites, made to sit in the Lagrange point between Mars and the sun. These could also function as solar concentrators, with the ability to direct concentrated light, or microwaves for power. But we will be there under domes centuries before we have the ability to thicken Mars' atmosphere enough for comfortable breathing, plus there's the fact that the dust on Mars is like some.of our volcanoe's plumes: essentially, tiny shards of glass, with a huge amount of it being salts. It will take a very long time to get that to become anything close to terrestrial soil.

Only in Long Term, yes, if we made an atmosphere on Mars in the next 100 years, it would slowly drain over the next 10.000 to 100.000 years. So it's not at all a permanent solution. - But you got time to solve it.

yah. seems bad.

@@Asfaril ... If it only takes a few hundred years to create a suitable atmosphere which then leaks out over 10000+ years then there would be no problem just topping up the atmosphere a little every 500 years or so. Or just continuously trickle charge it.

What about the 1/3rd gravity? It's my understanding that astronauts start losing muscle mass as soon as they reach the space station. Does the reduced gravity on Mars cause a similar harm? Theoretically, you may be able to build an atmosphere for the planet, but you can't adjust the gravity...
