CrashCourse (*Heavy breathing*) I've been acknowledged by a Crash Course Member (*Heaving breathing*). But seriously though it's a really well made intro. The ONLY thing I would like to change is the timing of the scene shifts so that they match the jingle of the theme. Other than the logo to the "telescope" scene, all the other shifts don't match the "DANANANA" of the song.

sara meachel It's because school isn't there for you to learn. It's there to teach you how to be a good blindly obedient robot. Sit down, shut up, raise your hand to pee, sit down shut up, stand in line, sit down shut up. It's based on the Prussian model of public education wherein good soldiers and good tax slave working robots are to be manufactured. The government cracks down and regulates home schooling and private schooling because they don't wish for there to be places of education where you can be entirely free of propaganda. They, in effect, have a monopoly, and it is very, very, very effective.
WTF are you talking about? The educational system is bad here because of so many kids. They have to spit out as much info as they can without confusing them by going so fast. That's why private schools are good, because they're schedule is based on the child's ability to learn.
The 1968 photo, Earthrise, taken from lunar orbit, really makes you appreciate the planet that we inhabit. We need to do everything we can to maintain that beautiful view.
Derek Swan well until FTL travel is invented and humans inevitably screw up the rest of wherever we go, before that it'd be like breaking planks from the only raft to build a fire
Da ve We'll destroy the Milkyway galaxy to look for more oil and then make a day called "Intergalactic alien apology day" to apologize for the trouble we caused.
krillinmesoftly except it has survived far worse than anything we have thrown at it... look up ice ball earth or the great dying... we are a biological blip. Don't attribute God like abilities to a race as stupid as human beings
Can you imagine the progress we would have made if George Bush, instead of talking about Terrorism, talked about Terrawrecking? I motion to, from this point on, refer to climate change as "terrawrecking" Oh, or maybe Terrorwrecking?
This series blows my mind several times an episode so much i'm sure i don't actually understand it. This one nearly answered a question 8yr old me had. If air does have weight, why can't you feel a perceptible difference when you walk outside? Also. Thank you to everyone that helped make this, & Crash Course in general. Learning is always beautiful, incredible and sometimes fun. Y'all have amplified that last property making my life more of the first two. I doff my hat to you, bravo
@@MrBassbump So it's all just a coincidence that the earth has been hearing up at record rates since the industrial revolution and humans aren't at all to blame?
Just in case this wasn't ironic. Have you ever done analogies? A is to B as C is to D. (denoted A:B :: C:D) They should have been on every standardized assessment you took. So Here's the simplest way of understanding it The Sun : A Star :: Broadway :: A Street Earth :: A Planet :: Mona Lisa :: A Painting So, yes, the Earth is a Planet and the Sun is a Star. One is the name of a specific one (though sometime a sun is algo genericized to reference a star with planets, but lets not overthink it). The Sun and Earth are ours. Earth or Eorthe (Old English), Jorth (Old Norse), Ertha (Old High German) used to just mean Land. The Sun was Sunne/Sunno/Sunna (same order I posted for Earth). They are just names. Not Ah-ha moments.
This is not a course about Astronomy, the is a course about everything! In ~10 mins you made me search for: (i) chemistry Fe, N, Ni, Ar, Ozone: why they are the most ingredient of the earth? (ii) the magnetic field of the earth: How it is created? and why it's close form the sun side and open the other side? (iii) Geology Plates tectonics: how they were first formed? and what laws describe their movement? (iv) Climate change: I am very informed about this subject, nevertheless you got me thinking about de-Terraforming, or is it Terradeforming? ;) (v) and most important, the link between them, as I already had a school (basic, dispersed) knowledge about them. Seriously, bad astronomer, crash course, you're awesome! I am going directly to patreon to double my pledge, you really deserve more :)
I love that there is another a geology centric crash course! I am only slightly disappointed that there has no geology crash course, but it comes up in other places like here and Big History. But I will still lobby for a geology/geoscience crash course! (you could even fit climate in that crash course).
Diana Peña The Greek philosophers didn't build Athens physically but they built its soul. The Acropolis may disappear one day but the thoughts of Aristotle lingers on ad infinitum. What is useful? Building stuff? Bankers playing with immaterial investment bonds? The Germanic tribes were more physically "useful" when they focused on the military than "airhead talk", but they sank western civilisation backwards by at least a millennium. Is your toaster "useful" because it makes toasts, therefore tangibly more important to life compared to philosophy? The material is "useful" in its lifespan, after which it's gone and prune to history repeating itself. The immaterial is useless in the short term, but invaluable to the building of other immaterial things like, oh I don't know, CIVILISATION?
Da ve YOU SIR! Have blown my mind.But seeing how you talk about how useful or useless is useful makes me guess you did have some sort of philosophy class.So i like to ask,do you know where to start learning the basics of philosophy?
I've, sadly, never seen the aurora either. However, when I was in AK back in '84, I saw the midnight sun while spending the night, during a 2-day arctic tour, in Kotzebue.
Thank you very much for making this video, Phil Plait and the rest of _Crash Course_ Astronomy! It was really interesting to learn about our amazing home planet, I just hope my future children and grandchildren will see the planets beauty before we humans destroy it all. Although I am very content with your videos, I was a little bit disappointed that you did not mention the Latin and Greek names of the planet: Tellus and Γαῖα.
the video is mostly like a recap of what you would learn in a course. so I think that's why he didn't mention Latin/greek names since people usually don't think its necessary to teach.
This channel is my go to revision channel and the way you explain everything makes it all make sense! Chemistry videos would be awesome to see and watch. Thanks for all the videos on behalf of most teenagers studying right now!
We all have something to learn from the Earth: the best protection against a raging universe is a fiery heart (and, uh... a magnetic field.) You stay you, Earth! 👍
I loved stuff like this as a kid too. Keep your kid interested in science! There are way more resources out there now than when I was a kid, so it should be easy!
+Hangshuo Zhang no, he's just exited about the idea that liquid water may mean that extraterrestrial (simple,but still extraterrestrial) life, which may also disprove a couple of religions but that just an added bonus/detriment (some religions are SO nice to meet up with and get to know).
+Kira Burns The water on Mars is kind of liquid. It's not liquid water like we have on earth. Water on earth flows freely, the water on Mars flows through different salts. Mars is much too cold and the atmosphere much too thin to have free-flowing water. To get an idea of what this looks like, try to imagine a thin layer of table salt on a dinner plate. Now add a couple or a few drops of water. Over the course of a few seconds, the water spreads out to form a homogeneous average wetness throughout the layer of salt (assuming there's enough water). This same principle is what we've discovered happening on Mars, except that it flows north and south through salt deposits over the course of seasons. The force that powers this water migration is, I believe, temperature. During the warmer parts of Mars' seasonal cycle, the water flows towards its equator, and towards the poles during the colder parts of the seasonal cycle. It may be the opposite flow pattern, I haven't read anything about it in a while so my memory is a little foggy on this part.
Even though I may know some of the facts or some of the videos are ones not specific to my interests I still love every video you guys post. Can't wait to watch the next one!
I love reading and following Phil Plait on Twitter, Facebook, Slate, and especially CrashCourse. I love reading the subject matter and I love how he puts scientific smarty pants things in terms that normal everyday dumb people can understand. I have to say though, reading some of his opinions on Twitter, and Slate seem kinda troll-y and almost invite attacks - such as "Stick to Astronomy." This is why I love CrashCourse. It is still him talking, but you can hear his tone, and his matter of fact style. It is definitely not troll-y, or inviting criticisms. His voice and tone kinda puts a different feel to the rest of his words online. I think CrashCourse is a good thing for normal everyday dumb people who have trouble avoiding arguments over things they aren't formally educated in.
Disciple Demon The earth's electromagnetic field generated by the counter rotating liquid iron core of the earth will disappear and the solar wind will no longer be kept at bay and our atmosphere will be slowly blown away into space. Earth will end up just as Mars is today.
Disciple Demon that depends on how you define "cool" but to get an idea of what is involved and how to analyze it, read up on the Kelvin-Helmholtz mechanism, and radioactive decay of thorium, uranium and potassium (i think those are the major geothermal isotopes) and their relative abundance in the earth.
When you compared water from the formation of the earth and water from comets, etc, and then called the former locally-sourced, I just had this glorious vision of the TRUE localvore who only drinks locally-sourced water.
It isn't just the crust that's broken into pieces called plates. It's also a brittle part of the mantle just below the crust. The crust and that part of the mantle is called the lithosphere.
Another great episode. :) I've read in a couple books, including "Rough-Hewn Land," by Keith Heyer Meldahl, that the motion of Earth's tectonic plates is due to the pull of the edges of those plates as they're subducted under adjacent plates and sink into the mantle, rather than to mantle convection.
I read a really cool article the other day which included an explanation on tidal heating. Really interesting. Unfortunately it turns out the entire article was utter rubbish which was rather disappointing.
Maybe we could call the antonym of terraforming something like "planetary scourgification", or "terrestrial dissonance". Any of my fellow word nerds have some ideas?
+KSI FlapJaksLol Xenoforming perhaps. That is shaping into something alien. Venuforming could be used as a more specific name. Shaping into Venus. From another perspective, Terradeforming, distorting away from Earth; though that one is pretty awkward sounding.
TonboIV I meant a term to describe the return of planetary normalcy before human intervention, but that's pretty good. I like the specificity of Venaumorph. For example, say Mars was colonized and then terraformed. The resources on Mars are spent after millenia, and humanity leaves it to return to its natural state; or directly affected negatively by humanity after it has been terraformed (war on a planet wide scale), then the carnage results in said return to normalcy.
Him: The Earth is a- Me: Star! Him: Planet. Me: ... I know that the Earth is a planet, I just wasn't paying very much attention when the video started... whoops.
How about a brainwave, atheist? You know, nobody actually likes atheists of you denomination. You're all brimstone and dogmas, but no brain. You think you are always right and always the most intelligent people in the world, but when push comes to shove, you usually end up looking like brainless buffoons.
I LOVE U CRASHCOURSE! UR AWESOME! I WATCH 3 OF UR VIDEOS EVERY SINGAL DAY! OH AND I SUBSCRIBED. THIS CAN MAKE U VERY SMART. I'm saying to the parents who read this comment to show this to their kid home-schooled or not. it teaches u all about space and it 100% child friendly. My eight year old sister loves these videos! It teaches u about other stuff other than space. For example, it can teach u about body health, I think I saw a video about that.
i like the way the earth rotates, really makes my day.

So true. If bacon's taken away from us then the world shall end.
Did anyone else shudder at seeing the temperature go up from the late 1800s to modern day?
No, because i have air conditioning.
No because data is manipulated to scare people like you who fall for that dribble

The Sun is a star and now Earth is a planet! I'm not sure what to think anymore
the sun is not a star,and earth is not a planet, earth is flat.
Just in case this wasn't ironic. Have you ever done analogies? A is to B as C is to D. (denoted A:B :: C:D) They should have been on every standardized assessment you took. So Here's the simplest way of understanding it
The Sun : A Star :: Broadway :: A Street
Earth :: A Planet :: Mona Lisa :: A Painting
So, yes, the Earth is a Planet and the Sun is a Star. One is the name of a specific one (though sometime a sun is algo genericized to reference a star with planets, but lets not overthink it). The Sun and Earth are ours. Earth or Eorthe (Old English), Jorth (Old Norse), Ertha (Old High German) used to just mean Land. The Sun was Sunne/Sunno/Sunna (same order I posted for Earth). They are just names. Not Ah-ha moments.
This is not a course about Astronomy, the is a course about everything!
In ~10 mins you made me search for:
(i) chemistry Fe, N, Ni, Ar, Ozone: why they are the most ingredient of the earth?
(ii) the magnetic field of the earth: How it is created? and why it's close form the sun side and open the other side?
(iii) Geology Plates tectonics: how they were first formed? and what laws describe their movement?
(iv) Climate change: I am very informed about this subject, nevertheless you got me thinking about de-Terraforming, or is it Terradeforming? ;)
(v) and most important, the link between them, as I already had a school (basic, dispersed) knowledge about them.
Seriously, bad astronomer, crash course, you're awesome!

When earth core will cool down and what will happen?
Disciple Demon The earth's electromagnetic field generated by the counter rotating liquid iron core of the earth will disappear and the solar wind will no longer be kept at bay and our atmosphere will be slowly blown away into space. Earth will end up just as Mars is today.
Disciple Demon I don't know the time scales, but I suspect the Sun will be a red giant before that happens. :)

Another great episode. :) I've read in a couple books, including "Rough-Hewn Land," by Keith Heyer Meldahl, that the motion of Earth's tectonic plates is due to the pull of the edges of those plates as they're subducted under adjacent plates and sink into the mantle, rather than to mantle convection.

Well explained.
Doesn't friction from the moon's gravity help to keep the earths core going as well?
I read a really cool article the other day which included an explanation on tidal heating. Really interesting. Unfortunately it turns out the entire article was utter rubbish which was rather disappointing.
The only way the moon would directly cause friction between itself and the earth is if it was pressed up against the earth, so no.

The resources on Mars are spent after millenia, and humanity leaves it to return to its natural state; or directly affected negatively by humanity after it has been terraformed (war on a planet wide scale), then the carnage results in said return to normalcy.
TonboIV venuform I mean, my bad. I misread.
terrawrecked. its catchy. I could make a song about it
rate of change similar to growth of nails

In the beginning don't you mean "zero dimensional" points?
Phil Plait bro! You're awesome! :D
Him: The Earth is a-
Me: Star!
Him: Planet.
Me: ...
I know that the Earth is a planet, I just wasn't paying very much attention when the video started... whoops.
you talk like a pre school teacher but I'm still enthralled and I'm 32.
We are marsiforming Earth
Actually no, because mars doesn't have an atmosphere.
Neither will Earth, when we are finished.
How? adding carbon dioxide to the atmosphere is the opposite of losing an atmosphere.
How about a brainwave, atheist? You know, nobody actually likes atheists of you denomination. You're all brimstone and dogmas, but no brain. You think you are always right and always the most intelligent people in the world, but when push comes to shove, you usually end up looking like brainless buffoons.
How old are you? Is there a language barrier or something? Is English not your first language? I am talking about mars dumbfuck.
What a great show. And what a great host. Phil is awesome and i really like listening to him.
Wait, so I'm confused... why are we trying to colonize Mars when we can colonize Earth? Earth is clearly a perfect planet to live on... I dont get it?
this is the perfect crash course.

I LOVE U CRASHCOURSE! UR AWESOME! I WATCH 3 OF UR VIDEOS EVERY SINGAL DAY! OH AND I SUBSCRIBED. THIS CAN MAKE U VERY SMART. I'm saying to the parents who read this comment to show this to their kid home-schooled or not. it teaches u all about space and it 100% child friendly. My eight year old sister loves these videos! It teaches u about other stuff other than space. For example, it can teach u about body health, I think I saw a video about that.
