games like this make me think that this is how education should be done, it should be entertaining. If it's entertaining you have a better chances at having fun at the thing, and thus better learning results. Instead of the "oh god oh no, another test, pls kill me" kind of education we have now.

[@honzasenbauer612]

Yes and no. As much as I would love to learn everything from a game, that will simply take you more time and it cannot teach you everything, unless it becomes boring. KSP has kinda the advantage, that it dumbs down all of the processes behind the real world and it gives you more immediate control without needing to calculate much. And the player wants to learn just because wants ti enjoy more of it. But it takes longer for him to learn it than if he was in school with a teacher that can explain stuff for you (I know it doesn't really work like that in schools, but its much faster than learning in game) What I would do, is insert a game like KSP to your subject of study, to hook your students and to show what you teach them on examples in the game. That way people will be much more engaged in the boring stuff, as it allows them to have fun. And btw my school does this to a degree. My lectures from Basic Electro Engineering have us thrown in the pit with a Tokamak reactor. How it should work and how its built. But they show you a presentation, its quite overwhelming and you don't really learn all of this stuff. So I would prefer if someone made a game where you almodt realistically build some shit and try how it works. Ahh fuck maybe that can be my project for Bachelor's thesis if I get through this shit

[@rompevuevitos222]

@@honzasenbauer612 That's why they are used as a tool, educational games are often used in classes for younger kids to teach pretty effectively No one is saying "boot up chemistry simulator and become a chemist in no time", but simply "learning should be entertaining" Because if you're having fun, you're more likely to remember what you learned simply due to being a happy memory

[@TheKsenpai]

@@honzasenbauer612 you surely haven't gone to a public school where there are 30-50 kids in one class. You are not getting the teacher to explain jack shit. At least that's how it was for me, teacher simply doesn't have the time, nor the monetary motivation. Generally in cases like that, teachers have 1-3 favorites in class, and they might have a chance for individual explanation, but for everyone else in class? tough luck. Private schools are a different matter though.

[@honzasenbauer612]

@@TheKsenpai I know, that why I said in the () that it doesn't always work like that. I have gone through the same boring thing as you did, and I know its wrong, but what can we do with the teachers being demotivated

[@TheKsenpai]

@@honzasenbauer612 teachers are demotivated for two things, first one is low wages and second is too much worlkload. That's where education trough video games would help out a lot. not as a replacement for teachers, but as a tool that would lessen the workload for them and give more time for individual tutoring if their students need it.

[@noswear2346]

YES !!! i was waiting for you to do this series its Fing awesome cant wait

[@_Trash_Goblin]

I believe in a later video of the series he explains the heat generation around the craft isn't technically friction, but something else. Like the air particles are trying to move out of the way but can't do so fast enough. Heck if I remember the details, physics was hell for me. Can't wait to see your reaction to the rest, though!

[@MrEmiosk]

No... that is friction, the air atoms moves which is how heat works. Something very hot, its atoms moves very fast, if it is very very cold, atoms don't. The plasma flare around the space craft is not the vehicle burning, however, the heat generated by the friction against the craft, and how super condensed the air becomes in front of the craft, the air itself becomes so thick that it starts to cause friction within the gas itself, self igniting the gas which then becomes the the plasma flare we see. There's nothing technical about it, it is friction all the way.

[@J7Handle]

@@MrEmiosk It is not really friction, though. When you compress gas, the temperature increases, and when you decompress gas, the temperature decreases. Friction doesn't explain decreasing temperature in the decompression case, so clearly something else is happening here. Firstly, heat is really just disorderly kinetic energy. What we normally think of as kinetic energy is a bunch of atoms moving in one direction together, but heat is essentially a bunch of atoms bumping into each and bouncing around, or perhaps just vibrating in place if we're talking about a solid. Friction produces heat because atoms on different surfaces have weak forces between them called Van Der Waals forces, which transfer kinetic energy. But that kinetic energy transfers in a disorderly fashion due to the non-uniform nature of the surfaces, turning ordered kinetic motion into disordered motion, aka heat. So how are compression and decompression different than friction? In the case of decompression, as particles of gas move apart from eachother, they collide both less frequently and with less relative velocity (naturally, because they are moving apart). But heat is essentially the total disordered kinetic energy in the gas. If the gas particles are colliding with less relative velocity, then they are colliding with less kinetic energy. Less kinetic energy means less heat. In the case of compression, the opposite is true. As gas particles move closer together, they collide more frequently and with more energy, meaning more heat. When a vehicle reenters the atmosphere, it compresses the air in front of it, causing the air to heat up. This heat then transfers to the vehicle via conduction and radiation in the case of the plasma. Friction between the air and the vehicle generates negligible heat by comparison. This explains why blunt bodies receive less heat during reentry than others. The blunt body pushes the compression wave further ahead of the vehicle, which gives the air time to cool down via radiation before contacting the surface of the vehicle. Essentially, the blunt body uses the air closest to it as insulation from the air further ahead.

[@MrEmiosk]

@@J7Handle the gas molecules gets compressed, rubbing up against each other generating heat, density of the gas traps said heat between and within the molecules and said heat can't escape and the gas self ignites if compressed enough. Decompression disperses said heat out over a larger space making it appear to "lose" said energy. And because of the lack of density it radiates away quicker. There's no magic or unknown about it. Atoms and molecules vibrate/move, the greater the energy the greater and quicker the movement, when atoms and molecules have room they do not collide/bounce/vibrates on eachother and thus slows down as they lose momentum and speed.

[@DavidLanin]

As far as I remember its around 5% heat generated by air friction to 95% generated by air compression. The principle is pretty the same as in diesel motors where diesel fumes ignite from heat generated by compression and as such doesn't require any other ignition source like spark plugs in regular motor.

[@PerfectDeath4]

There is a meme out there, it shows a graph. X for the person's life progression Y for their understanding of orbital mechanics. There are spots along this graph where he marks notable events. First mark is for Highschool physics, his understanding of orbital mechanics goes up. Then the next mark is placed when he starts college/university physics and the line goes down. They realize they do not understand orbital mechanics that well, but it does trend up again after a while. Then they get a job with NASA and the line drops back down, it tries to go back up but kind of plateaus. That is until they start playing kerbal space program and suddenly they can rapidly run simulations and attempt orbital maneuvers within minutes instead of YEARS. Orbital Mechanics understanding goes up. A lot.

@@steven95N CKAN is supposed to prevent you from downloading conflicting mods, it could be that at the time, the creators never thought someone would need an FTL drive to do something, seen the video series, and updated it. also i personally prefer the FTL drive (stand alone) since it gives you a size limit you are forced to work with

[@CreepyPersonCube.]

Legend novelist Douglas Adams had a character who was taught to fly SIMPLY by mastering the art of flinging himself at the ground and missing. His tutor was a person with exceptional personal attributes (that are not named) who would jump out from behind things as the hero is falling, thus distracting him at the crucial moment, causing the miss. This is obviously the most advanced way to get into orbit.

[@BlackEpyon]

Just to clarify, no Apophis won't hit us any time soon. There was a big hullabaloo in 2013 about Apophis passing through what's called a "keyhole." This had to do with refining the measurements of it's orbit, so it's future orbit (and thus close approaches) could be more accurately predicted. The worry was that if it passed through this "keyhole," then there was a much greater chance that it's next orbit would take it uncomfortably close to earth - close enough that it would have a chance of actually colliding. It didn't pass through the keyhole though, so there's nothing to worry about where Apophis is concerned.

[@Discohydrus]

I tend to follow a lot of science channels, and I like that you actually pause the video to go into the science behind it, and it I believe it actually brings merit to the reaction content. I think you could be quite successful with these kinds of videos.

How I like to explain centrifugal "force": Every law of physics comes with assumptions. If you break those assumptions, you cannot use that law to accurately describe your situation. Newton's laws have an assumption about the reference frame you are using. A reference frame is what you measure things relative to. For Newton's laws to give correct results, you must use a reference frame which is not accelerating and which is not rotating. However, it is often much easier to express a situation from the perspective of a rotating (invalid) reference frame. You can make adjustments to Newton's laws to create correct results in the rotating reference frame. These adjustments all look like accelerations relative to the rotating (invalid) reference frame. In a valid reference frame, accelerations are always caused by forces, so these apparent accelerations can be described by apparent forces. They are: The centrifugal force, which has objects appearing to accelerate away from the center of rotation. This is required to explain the effect of a centrifuge when using the rotating (invalid) reference frame. No such force is required to explain the phenomenon from a valid reference frame. The Coriolis force, which has objects appearing to accelerate upspin or downspin when they move outward or inward. This is required to explain the Coriolis effect when using the rotating (invalid) reference frame. No such force is required to explain the phenomenon from a valid reference frame. The Euler force, which has objects appearing to accelerate upspin or downspin when the rate of rotation decreases or increases. This is required to explain why you feel a merry-go-round starting and stopping when you're on it when using the rotating (invalid) reference frame. No such force is required to explain the phenomenon from a valid reference frame. Of interest: while these are all often described as apparent forces, they are in fact apparent accelerations, and describing them as forces requires multiplying them by the mass of the affected object. Similarly, Newton's law of gravitation is a term multiplied by the mass of the affected object -- begging the question of whether gravity is just an apparent force caused by using the wrong perspective. Sure enough, general relativity describes gravity in such a way.

It's been moved to a risk rating of 0 years ago. It certainly can't hit in 2029, and there is a miniscule chance it could be setup for an impact in 2036 by the deflection caused in the close approach, but even this small chance has come under question. If it did hit it would certain be locally catastrophic (apprx 1k megatons), cause regional tragedy and disaster, might even cause global economic uncertainty in a lot of the world. It wouldn't end the world though, and if anything it would immediately wake the world up to the real tangible threat posed by impacts and would push space powers to find serious solutions. It would be unfortunate if something like this happened - it probably won't be that asteroid, though. More likely one that isn't known or is poorly understood (in which case, you couldn't know anyway)
