i'm trying to see how long it takes a 500 kilowatt oxygen iodine laser to heat up my cup of noodles
i've done it by two seconds so let's do some calculations let's see if that works out
so i'm a sagittarius which probably tells you way maybe even at the initial moment of creation
the fundamental forces lack symmetry okay let's pause it here and talk about this super asymmetry
it's clearly a spoof of super symmetry. G'day my smart mates my name is dylan dance, i'm a physicist
from the land down under - grab a coffee grab a chair, grab a Vegemite sandwich? Look, grab whatever you
want to grab, let's talk some natural philosophy so today we're going to watch some big bang
theory, of course i've seen a little bit of this but i haven't watched too much and there's a
lot of great stuff related to physics so i thought we could make a video and watch some and
i could break down some of it for you uh maybe you know explain some stuff that you missed
or we can do some reality checks on some of the stuff they claim and we can see if it works out so
anyway let's get straight into it. If you haven't already please apply some time derivative of
momentum onto that subscribe button. Serious stuff leonard did you do this actually that's my work
wow yeah well there's just some quantum mechanics with a little string theory doodling around the
edges that part there that's just a joke it's a spoof of the born oppenheimer approximation
you're like one of those beautiful mind genius guys
yeah i have a board if you like boards this is my board
holy smokes if by holy smokes you mean a derivative restatement to the kind of hearted
at least i didn't have to invent 26 dimensions just to make the math come out
to invent them they're there and what universe in all of them that is the point
hello leslie hi leonard leslie i would like to propose an experience leonard right those are
important in the lab leslie i would like to propose an experiment hang on i'm trying to
see how long it takes a 500 kilowatt oxygen iodine laser to heat up my cup of noodles
i've done it by two seconds 2.6 for minestrone
so let's pause it here because we can actually do some calculations and see if that uh those
numbers work because she said uh takes a he said it takes about two seconds uh if you had
a 500 kilowatt oxygen iodine laser so let's do some calculations let's see if that works out so
so i've done the calculations as you can see and if you had a 500 kilowatt oxygen iodine laser
it would actually only take 0.167 seconds to heat up your noodles you'd actually only need a 41.9
kilowatt laser to do the job in two seconds but there is a problem there is a problem however
i did some extra calculations because it's not enough to just show
how quickly the noodles are heated what about the container so the infrared laser
is going to also heat up the container and i used a high impact polystyrene container
and worked out it'd actually only take 451 microseconds for that container to melt
so what you what's going to happen is the container is going to melt well before your
noodles cook and your two minute noodles are going to be on the floor cold so yeah you can't really
do this in reality so don't try it at home so if i make slightly asymmetric knots with
sheets in four dimensions then i can bootstrap the whole idea to a large asymmetry in 11 dimensions
well maybe even at the initial moment of creation the fundamental forces lack symmetry
everyone's waiting what are you guys doing super asymmetry
super asymmetry is that a thing we're inventing it right now don't you think this can wait until full
don this is in okay let's pause it here and talk about this super asymmetry it's clearly a spoof
of super symmetry which also isn't a real thing currently there's no experimental verification
of it um but what is it well in the subatomic world uh subatomic particles make up everything
um and supersymmetry suggests that all of the particles in the standard modical particle
physics has a supersymmetric partner essentially extra particles that would exist in tandem with
the already identified ones so you wouldn't have to change any of the existing equations under the
under certain transformations um and so this would have pretty deep predictive implications
what about this super asymmetry well that's not a real thing but there is something called
asymmetry induced symmetry um and it has to do with is this effect um well there are instances
in which the behavior of a system can be symmetric only when the system itself isn't so that is
probably the closest i can get you to this super asymmetry but i think that little effect is pretty
cool hey the future the show in back to the future too is only a year away right phil a lot of things
in that movie haven't been invented yet how cool, I'd tell you a time travel joke but you didn't like it.
out the scientific basis for marty's hoverboard but that would have universal application
it's possible at absolute zero but we would have to remove the temperature restrictions
oh i have so he said it would be possible at absolute zero uh the reason why morty's hoverboard
would actually be possible is because if you uh cool a superconductor to near absolute zero
now a superconductor is just something that allows electrons to flow without any resistance
they freely flow um if you cool this thing down to near absolute zero well they actually repel
magnetic attraction and a superconductor will float above the magnet near absolute zero now
we won't get into why that is but that gives you some idea um but there is a a bit of a problem you
can't actually get to absolute zero uh and that's because to get to absolute zero uh it would also
require you to get to zero entropy and you can't get to zero entropy it would take an infinite
amount of energy and a system at absolute zero still possesses quantum mechanical zero point
energy which is the energy of the ground state and zero kelvin and there's just no removing this
kinetic energy of the ground state so wait until you see this it's fantastic unbelievable see what
it's a stephen hawking lecture from mit in 1974.
this isn't a good time it's before he became a creepy computer boy
that's great you guys have to. C an confirm that's what i'd be doing in my spare time
looking for lost Feynman lectures or just random Feynman videos on youtube
check out uh Feynman's video on Tanu tuva video on youtube, if you've never seen it such a good time
oh a number of significant innovations have been inspired by science fiction
the the geosynchronous satellite from arthur c clarke uh the motorola flip that is true
i always tell people that one if you look on the bookshelf over there i've got just about
every arthur c clarke book my favorites probably this one
2001 a space honestly if you've never read the book it's incredible there's a few of them um
and i highly recommend giving that book a shot arthur c clarke is just the best and if you're
not interested in sci-fi you should be because i've always looked at it it's a way to glimpse the
future you know we only have about 100 years each so none of us are going to get to live to see the
future if there is one for humanity and sci-fi gives you a vessel to travel into the future
and you know you're shackled by the laws of physics and you get to kind of see maybe what
it would be like in the future so that's why nerds enjoy sci-fi i'm a sagittarius which
probably tells you way more than you need to know yes it tells us that you participate in
the mass cultural delusion that the sun's apparent position relative to arbitrarily
defined constellations the time of your birth somehow affects your personality participate
I think what sheldon's trying to say is that wouldnt have been our fir st guess
that's pretty much me whenever anyone brings up astrology if you didn't know astro logy astronomy
very different things whenever you tell someone astronomy they instantly think
you're talking about star signs or something it's really sad
but uh yeah just to rehash what sheldon said astrology is pseudoscience so don't buy into
it if you do but if you're on this video i'm sure you already know that so all right i think that'll
do it for this video if you have any good ideas for things that i can react to leave a comment
