yeah you know good day smart person my name is dylan i'm a physicist from the land down under
grab a coffee grab a chair grab a vegemite sandwich look grab whatever you want let's
talk some natural philosophy so today we're going to be watching some more attack on titan the last
video is doing pretty well people are enjoying it learning some stuff so let's watch some more
i thought it was pretty interesting uh to say the least it was pretty fun watching people get eaten
and all no look it's pretty intense so if you haven't seen the first video and if you haven't
seen the show you know you might want to uh click away if you're fairly squeamish but anyway let's
get into it let's uh break down some of the physics of attack on titan and see what other
cool stuff we can talk about so i was going to watch more of the show but too many of you
couldn't keep your mouth shut and you spoiled all the secrets in the comments of the last video and
now i know the walls weren't actually built by the human so my uh discussion was completely pointless
and all the people saying i am irwin's father not sure i get the joke so someone might have
to explain it in the comments is it that i look like him or is there some inside joke that i'm
missing some people were challenging me about the 3d maneuvering gear in the comments so to put that
one to rest uh i didn't really explain why you'd be fainting so if you were pulling many g's as you
get launched in all these directions and multiple axes up down diagonally you'd be pulling many many
many g's and the reason why you faint is because that the blood uh can't get to your brain because
your blood is obviously used to ears gravity uh and you know it can usually get to your brain
um but as you experience a higher level blood it can't get to your brain and you faint
so and that happens at about nine g's um a normal person at about five g's will faint
but you can get somewhat used to the lower level of blood supply to the brain as fighter pilots do
but for us normal humans 5gs and you're done so these people using the 3d maneuvering gear
probably pulling many g's that's all i'm going to say i haven't worked it
out i'm sure somebody has out there so if you know how many g's comment down below
but anyway so yeah 3d maneuvering gear is dead you it's not feasible it's not practical and it's just
not going to work but anyway let's find some other stuff in the show that we can talk about
some more of the very unrealistic maneuvering 3d maneuvering here

so i've noticed this er when the titans transform i mean when the people turn into titans this huge
bolt of lightning um i mean it looked a little bit different when aaron was transforming
it was like a uh almost like ball lightning so let's talk a little bit about lighting because
lighting is really mysterious still we currently still don't understand lightning all that well or
what even causes it so maybe we can talk a little bit about normal lightning and a little bit about
this ball lightning so normal lightning if you didn't know isn't actually that thick
it's only about a finger width it's like a couple centimeters so but its temperature is about as hot
well actually it's about 30 000 degrees celsius so that's hotter than the surface of the sun so stay
away from lightning so what triggers lightning these electrical bolts from the skies well you
have electrical charge building up in clouds and you've got the opposite charge in the ground so
that creates electrical attraction but what causes these bolts you know to occur at any given time
at any particular location compared to you know a completely identical in another point in time
and another location what it's it's not clear we don't know why lightning occurs at a particular
time at a particular location over the past 20 years has actually been a few papers published
suggesting that maybe cosmic rays are triggering lightning and cosmic rays are just high energy
protons and atomic nuclei that are traveling at nearly the speed of light and they come from
the sun other stars and sort of things like that so you get these high energy particles you know
hitting the atmosphere and they're interacting with clouds and that causes these these high
energy collisions cause some sort of triggering of lightning but there's really no proof of these
uh ideas currently but it's an interesting idea another really cool thing to consider is that
these lightning bolts may actually be triggering high energy particles and what i mean by that
is that we've detected some x-rays from lightning bolts and further we may have actually detected
gamma rays coming from lightning bolts which means that lightning might be generating antimatter how
cool is that because antimatter and normal matter annihilates when antimatter pops into existence
and when they annihilate this is what creates flashes of gamma rays
and we actually detected these gamma-ray flashes coming from powerful uh thunderstorms uh from
satellites that are normally used for astronomical stuff and to finish off this massive tangent about
lightning i wanted to tell this little story that i found super fascinating so in the 18th century
it was believed that ringing church bells actually repelled lightning and a lot of the church bells
at this time actually had the inscription uh folgiro franco which means i chase lightning
so during a big thunderstorm these church these bell boys would run up to the bell tower
they'd ring the bells and that's probably the worst place you could be in a lightning storm so
as you can imagine a lot of people died and i think it was between 1753 and 1786 uh it
was something like 103 people got killed by lightning strikes uh so yeah they then banned
uh that whole sort of method of ringing bells during storms but anyway i thought that was an
interesting story so i've changed my mind i actually might save the ball lightning
discussion and some cool facts about it for the next video um in case we do another one on attack
on titan and maybe that relates to you know i've noticed there's different titans right and so when
aaron transforms you know it looks like ball lining whereas others it seems like you know
a bolt of lightning so maybe that has something to do with something i know there's a lot of people
uh writing down in the comments of videos about theories of these anime shows and
some people seem to find some of the stuff i say interesting and relevant for unraveling some of
the mysteries of the show so who knows maybe that's there's something to that as well so
yeah make sure you subscribe and stick around and we'll talk about bull lightning in the next one
that's a big rock
foreign
so could he carry such a big rock who knows but uh another thing that uh i should point out is
the leg width of uh say aaron's titan well it should be a lot wider because uh as you get
larger there's a lot more pressure on you and it increases quite a lot the bigger you get so
it doesn't make a lot of sense for aaron's titan or these titans in general for their legs to be
you know the same sort of scale as a normal human the same ratio and so i mean take an
elephant for example in a deer an elephant's legs are very wide and the bigger you get
the width of these legs would have to increase to support the pressure so it doesn't make a
lot of sense uh say for aaron's titan to have you know skinny little legs and being so huge
but anyway looking into that too far the rock yeah probably but it looks pretty huge
almonds probably my favorite who's your favorite leave a comment down below
foreign
okay that's pretty interesting so this coordinate thing
not really sure there's anything that i can connect to reality and physics um
apart from wi-fi and invisible lasers in the air i have watched a little bit of the show and it
is pretty wacky i mean i'm really enjoying it it's cool but some of the answers to some of
the questions that people have about the show were pretty out there so have you ever thought
about whether or not it's possible to transfer consciousness to say a computer or the cloud
uh well imagine that it is so maybe what this uh coordinate and these paths are uh is simply
you know consciousness some sort of consciousness that's in the cloud and uh from the previous era
of humans uh like it's been explained in the show so maybe that's what's going on you know these
they mentioned that memories are contained within these uh paths and the coordinates so
maybe that's what's going on and this the founding titan is this
consciousness in the cloud so who knows i mean i certainly think consciousness is nothing but
atoms and uh you know physics-y stuff going on in the brain and i think we'll be able to replicate
that using computers to be honest so some sort of artificial you know intelligence i think is not
too far away so maybe uploading consciousness to a computer isn't all that far away
um so maybe something like this coordinate or these paths are aren't too far off you
know something in the far future some sort of technology but i think we're reaching so anyway
all right so that'll do for this video i couldn't really find anything else to talk about that was
interesting so i think we'll just keep this video short and if you haven't already please apply some
time derivative of momentum onto that subscribe button and i'll see you guys next time catch ya
