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
