good day my smart mates my name's dylan dance i'm a physicist from the land down under
let's watch some simpsons and this perpetual motion machine she made today is a joke it
just keeps going faster and faster i see these perpetual motion machines all over the internet
so i should probably say according to our current understanding of physics they're not possible
first law of thermodynamics you can't create nor can you destroy energy can only change from
one form to another so for a perpetual motion machine it's producing some work without energy
input it doesn't make any sense lisa get in here in this house we obey the laws of thermodynamics
that's what we were just talking about i'm a nerd so am i definitely a nerd
i remember seeing this in a physics meme and they were claiming that the simpsons predicted the mass
of the higgs boson which is known as like the god particle the mass was only fairly recently
confirmed at the large hadron collider and this episode came out in like 1998 so people were you
know doing that whole simpsons predict of the future once again if you look these numbers up
and plug them into the equation it predicts a mass of 775 giga electron volts which is
quite a bit higher than the estimate produced by the large hadron collider
back in 2012 when the particle was discovered which is 125 giga electron volts but that's pretty
close in my opinion so not a bad guess considering you know it's homer and it was 14 years before
physicists at cern made those calculations so you might have heard of the higgs boson before
also known as the god particle and people tend to think it's what gives everything mass it's
not quite true it's the higgs field that gives all the other elementary particles their mass
but it's actually not where most of the mass comes from most of the mass comes from protons
and nuclei binding together real a mystery why some elementary particles interact more
with the higgs field than others we don't quite know so that's just another reason to get
involved in science the higgs field is like an invisible field that permeates all space
and the higgs bosons are like the quanta of energy of this higgs field so they're like the little
building blocks of the field they're not quite particles because in quantum field theory
this higgs field is a quantum field there's no particles it's we we often refer to them
as particles but we don't actually mean particles so it gets a bit confusing what we mean when we
say particles is like you know uh some of this field coalesced into this small little region so
it's more like a wave it's not really a particle and we've haven't used that idea for a long time
but we still we still say particles where does the higgs field come from we have no
flipping idea what we currently think is that surely after the big bang particles had no mass
everything was massless and you had this hot primordial suit is what we say and then
spontaneously this higgs field turned on why did it turn on if you can answer that
you'll probably win a nobel prize but anyway let's keep watching the simpsons very good
dogs genius i was gonna say it's not that funny so what it says is uh today's math joke
the square root of negative one is i imaginary number two to the power of three is eight and
you've got the sum of pi so it's saying i ate some pie and it was delicious i'm pretty sure
one of the creators of this show is meant to be a mathematician so that explains this math joke
and some of the other super nerdy things like the higgs boson equation i wrote this poem for
you it's called cat math four paws plus one tail plus nine lives equals one special cat
let's confirm that four legs one tail one special cat calculations work out
can't not get my cat when cats and math are mentioned pish-posh professor what makes a guy
and a girl click isn't science it's chemistry which is science word which is easy physics so
if you want to get girls get good at physics homer scientific research can solve anything
except for cold fusion quasars the interior of black holes and what preceded the big bang
but everything else hold up we've pretty much solved quasars we know what they are
cold fusion yeah it was still a while off that i think we'll solve it though science has got
that one the interiors of black holes that one could be the trickiest i still think science can
help us out there though we just need a black hole to experiment with the before the big bang
well yeah we that's a that one's a big ask but again it's possible and uh roger penrose actually
met did some speculation recently after he won that nobel prize in physics and he proposed that
there was just more universe before the big bang and the universe is this cyclical thing where
it eventually gets to this stage where everything dies off and that's what we think will currently
happen in our universe in the far distant future everything there will be nothing
every everything will be moving so far apart as space is expanding at an accelerating rate
you won't even have black holes or stars because everything is expanding
and getting further apart so eventually all the galaxies will die they'll stop producing stars
and eventually all the black holes will evaporate because of hawking radiation and you'll have
nothing and at this point penrose suggests that it's kind of like the same as having nothing so
somehow the universe will be reborn i don't know he compares it to the size of a photon because
a photon size isn't well defined it's uh it's kind of zero and zero is kind of the same as like
infinity so yeah science i think can solve all of those problems behold gravity in all its glory
pretty lame milhouse that's exactly what i say when uh when i'm in an elevator and it comes to
stop uh professor don't be offended do you think it might be your voice why what's wrong with my
voice with the up and down and the extra words and the terminal nonsense in the hiven cliving wagon
oh my god it's the voice that how i speak let me know down in the comments if i have a nerdy voice
hey flanders heading for church well i thought i could save you a little time
i accidentally proved there's no god we'll just see about that uh-uh
well maybe he made a mistake nope it's airtight can't let this little doozy get out
that's hilarious uh don't know what to say about that could you imagine if we were actually able to
do that i don't actually think anything would change we already live in like an alternative
facts reality so i'm pretty sure everyone would just continue doing their thing and
wouldn't even give it a second thought of the museum
yeah evolution
how can you put up an exhibit on the origin of man and not have one mention of the bible oh we do
my most cherished beliefs a myth daddy was mommy a monkey i can't remember no one was ever a monkey
everything is what it was and always will be god put us here and that's that but you said a stork
brought me yeah that was god disguised as a stork who brings baby storks there's no such thing as
storks it's all god please bless daddy we're still monkeys by the way we're just some smart primates
or maybe just an advanced lemur who knows i don't know which is a bigger disappointment my failure
to formulate a unified field theory for you so what he means there is by the unified field theory
is uh our current best series quantum field theories which are field theories and the
best one is the standard model but these field theories don't incorporate gravity
whatsoever they incorporate the other three fundamental forces but they just leave out
gravity so a unified field theory would bring together relative general relativity and quantum
mechanics because general relativity is all about gravity quantum mechanics is very small stuff
better than iron man his iron man was meant to be like an engineer so that's the physicist version
of the iron man are we gonna do any actual math problems problems that's how men see math
something to be attacked to be figured out but isn't it i mean confidence building can't replace
real learning uh lisa sounds like you're trying to derail our self-esteem engine well that's a
little bit sexist but uh there's definitely not enough females in physics so if you're a female
out there and you want to go into physics you definitely should some of the best physicists and
mathematicians in history have been female so we need more of them in all right that'll do it for
today's video clearly if you want to write a good show you need some math geeks because i just did
some research and a whole bunch of the writers are mathematical heavyweights a few of them have phd's
a few have gone to harvard to study math so there you go if you want to write a good show
go study math don't forget to subscribe and like this video and i'll catch you guys next
