well and right copy I don't think I need to introduce myself to other this is the last hope for the die we will have a little bit of wrap up I'm off to this I am and we will have the time to high to reflect and maybe some questions on some of you wanna get high but let's get cracking because of good about well probly twelve
minutes is Montauk by be marked as a fifth day sudden panic if that thing goes iva sigh he we got the mathematics of white Los well let me start with these last year I went surfing in Fiji and the our resort had a photographer following us around taking these photos which is really great except that I couldn't help but notice these somehow it managed to become
five kilograms I've a white couldn't believe my eyes so I did what I tell you today I I it lists and I moved more and within three months I discovered I'd lost six kilograms of then Aidid what a normal person I did physics but anyone would do this autographed my white and when I did the linear regression I discovered that lone behold on average I'd been
losing IT five grams a die which got me thinking infected me very curious about this question that I've since discovered most people have no clue about in fact I've never even thought about these and to prove my point of my little video I'm Bandai bitch and the question was this when somebody loses white where does that dog what is the become how does it get out
of your body you probly dumb struck by the question these people were so listen to this where's the guy where's the white guy him cope with the guy and well well because I don't know I will move that nine nine I think it needs it but that was the mysteries of science with how it is applied like thing to really fall into the eva if it
gets you zap you invent another dimension doesn't go anywhere we silliness is that it comes up with some may become nothing does exist anymore I guess that's a very good question requested what is fascinating question what would you say goes right in the Crapper me sway more skill and sweat remember rights right their ops then he flew James up a bug's life each that's where it
goes back I will basically been it up was in a deep down at the vanity he energy burnt in energy Arnett as energy needs though right now I get you got me there I'm not quite sure he said what the heck is going on we're in the middle of an obesity epidemic out I need to tell you about it so why don't these people know the
answer to this fundamental question because not one of them was right and we do know the answer this is not groundbreaking stuff from that to tell you to me just remind you a few things you do now I was the chemical formula for water hatch to our chemical formula for carbon dioxide you'll know it right so you know what human fat is might've so what is
the chemical formula for human fat there is such a thing believe it or not been nine since this say fifty five height one I full I seeks that's the chemical formula for the average fat molecule in the human body some of the molecules might have a few more carbon atoms and a few more hydrogen somewhat have less by all have just six oxygen atoms it's very
important helpful for Liza but this is the average fat molecule height as say fifty five height one a four by six because the very clear that these the difference between vast and vast is C. fifty five height one of four of six I kid you not and the difference between that and that sign thing say fifty five highs wonderful I seeks so how does this stuff
get out all the human body well he's the general equation pretty sort of interesting slightly complicated not if you've done some you ten chemistry surely this is viewed ten chemistry all I was not really but he's what it says fat plus oxygen gives you carbon dioxide and water that's what it becomes and the distant by chemists of nine this for ages you in how that the
X. how that that's what happens to it amazing now that little arrow day is kind of %HESITATION I've simplifying something called by a chemistry that's three years at university and my apologies the by chemists I don't mean to oversimplify that I'm trying to get to the crunch it's really complicated doesn't just come out of you for no reason you've got to do stuff eight less move
more are what will come to that minute but look when you want a list why you wanna lease kilograms that's all kilograms all that stuff there to what people say I hate opens up his energy because that's what we've been telling them all this time and it's very confusing because energy has different units killer jewels or you might use calories and yes that's hate that's motion
when you move or it thinking your brain needs energy or it's growing but that's not where the fat guys so it would be talking about here well I'm let me just show a couple more things such I've got some carbon dioxide he is in its frozen form we call it dry ice it's carbon dioxide has mass thing is you don't use to seeing it but here's
some dry ice and it's heavy and if you put it in water long behold it does this cool thing in bubbles like evil saying that before well that's cabin ducks autumn water that's what fat is kinda might out of but is not fat I'm not making fat that is not fat so how does that become facts well it doesn't just like that become sure the first
plants Mike fat will I stop the whole thing plant takes six molecules of copper oxide and six molecules of water uses an amazing chemical cool chlorophyll hold them together and then some lives comes in and bonds those molecules together that become Suga see six height twelve I sixes glucose fructose sign formula seasick Hutch robotics I'm sucrose is glucose plus for does stuck together Monessen page two
I molecules sites and I do the math see tween T. nine twelve hatch twenty two I five rot well his son this is so because plants market and it's this stuff join together it's now got chemical energy holding these molecules together so that I just fly around like that and by the way if you drink vast six hundred mil of lemon flavored suffering you get at
seventeen Tay spins this stuff I mean then I'll just quickly show what that looks like his one to three for five six seven I nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen rot so if you drink that is the equivalent of doing what I just did the spin exit munching it all down exactly the Sinai difference so if you do do that then what happens
well let me explain something else that I've been telling kids for a little while and they get these site when you ate food it's not in your body straight away swallow that sugar it's not emu yet so he's a pool noodle rocker hoe running through it and he's an almond never put the almond in there can go all the way through and at the other end
lifted to his another comment if I put an almond in here is where is the almond you inside the almonds in the pool noodle I carry but is it in the phone that the pool noodles might've now I've because not just in the hole that runs through it that's food useful if it is not a news it's in the hall that runs from here to the
back door and getting food into school digestion so with this stuff you've got a bright the bone that's holding the photos to the glucose in the city to do that than that stuff can cross the barrio internal skin and into your body and then I can guarantee you a blot that's I'm digestion but not it's not metabolism yet it's going to yourself and then you get
a better job and if you don't then adopt if you eat all that sugar if you've had the three meals in the diet your body doesn't Weiss that doesn't come out here the stuff that comes out the back door was never in you apart from a few molecules of cholesterol is his father that you couldn't digest plus the bacteria that living you got you lose about
five hundred billion of those in one single city ng the tiny that's many times the population of the earth every time you flush the toilet it's amazing but that stuff was never really need sigh at his what happens if you dont then metabolize that sugar will then it's gonna get converted into the stuff that we will have a problem with fat now that it is true
that you do brute Brady's this stuff out right if you metabolize sugar you turn it back into carbon dioxide and water sigh every time the exile out comes a bit of carbon dioxide you can't sit this is the problem this is why people don't know how you lose white site they got off track some breath of and how that five percent of the air in there
is now carbon dioxide because I it's come out of my lungs I've got some liquid nitrogen he and I'm gonna use that to phrase this a liquid nitrogen is Manisa hundred ninety six very handy I'm whether that's right then it all just port stride on said be a little bit careful with this stuff I use it all the time folic little blase I don't mean to
I am it's please respect this stuff if you play with it the why you would respect boiling hot water now he poured onto a balloon the balloon does not pop which is incredible the non virgins minus a hundred ninety six oxygen turns into a liquid of Manisa hundred ninety three saw the oxygen in the balloon is turning into a liquid carbon dioxide turns solid of their
big ball of it there but it soon so the Monessen anti I saw it in the balloon now I have frozen well I have who fought oxygen and frozen carbon dioxide Emina type that you'll see them sigh just take awhile the balloon to go live it clear at the top the nitrogen in here areas seventy nine percent nitrogen the nitrogen is in the top of the
land but now look about liquid them Nicky say that that's the oxygen from my breast that I hadn't used but once it's all gone they'll be some white powder lift rod the white powder is breakfast that's the carbon dioxide the carbon atoms I I in the last twenty four hours and what a blown them they get warm enough to turn back into gas and I vanish
and people think there's nothing in the balloon the billing has mass buzz atoms have mass you can see carbon dioxide has mass when you solidify but when you break that I don't see it and would be confusing papal by talking about killer joules or calories and they've really important but people do not seem to understand that when you lose what you losing at a conscious ten
atoms into nothing in fact Saens teaches that they alienate the Chinese why teach chemistry does papal and many in this room think that you can ten atoms into energy well it's one of the founding principles of modern chemistry you cannot turn an atom into pure energy for the conservation of mass before reaction an after action we take kids that have the same number of atoms school
stoichiometry well we have been taking it very well at all because people think you contend fat which is kilograms into not often or just killer jewels can't do it so he was my big fat question I'm a physicist on you that it Ammar question what if I've got ten kilograms of this stuff then how much carbon dioxide does that become and how much water and tens
at that that's really simple to this is you ten chemistry and yet ten maths you made the periodic table of elements you have to look up hydrogen carbon and oxygen there they are now the periodic table has an important for my shin on the white of a single atom of these elements so the wife of a single atom of our carbon is twelve point zero zero
one as a zero one one atomic mass units doesn't matter what our kilograms just yet I'll show you one minute with the fifty five dollars a night average fat molecules so this eccentricity point five nine what about the hydrogen ahead is a hundred and four of those sigh we have Iman molecule of fat hundred full point I three atomic mass in I can't gripe the oxygen
is a little trickier this stumped me for quite sometime effect I ran around and I couldn't get a very clear answer on this because it doesn't seem that many black himself sort of at at this why this though because this silly or whatever they just haven't thought about in this white which really surprised me because this bit of information is the most motivating bit of information
I had in my personal little Jenny of losing seven ten kilograms in six months it's all gone hole rated out amazing you could anyone can do this is not hot umps I how much carbon dioxide and water well the oxygen's important Essex atoms of it in a molecule but what are they going to become of the gonna go as carbon dioxide are they gonna go is
water the gun some ratio of the TV Hattie figure this out took me I just and then the answer turned up in a very old Piper I'm from the nineteen forties when I type in a wartime labeled the oxygen atoms my them I put some an asa type of oxygen on to the house and a hostage in IT at diver to monus the moss had it
done in the belly button that time out in their breasts so Warda had the oxygen in it but then that oxygen tent up in the X. how breath which showed that oxygen atoms are exchanged between top and oxide molecules and woman accuses a really good reason for that his %HESITATION some phenolphthalein in wartime on speed how to pronounce I'm going to make because of left its
it but look if we bomb here Chinese calla right whoop de do was a shy shows the carbon dioxide dissolves in water foams carbonic acid is an exchange of oxygen atoms side what is told me is that I am the why the six atoms are gonna leave your body is in the same Russia that they exist in the molecule so that's at two to one ratio
so that means for will go at his cabin outside and to guide his %HESITATION wartime that's right now I know the answer so now you do the math so I've got the first two dances I'm gonna add to the cabin's the white of four of these oxygen atoms they gonna go out with carbon south chalk that up there and of the two to god so two
times that day we got check that with the hydrogens because they getting out some hydrogen and now I can figure out the right Shia of carbon dioxide and water from my fat side is the titles and now we're just gonna divide it by the title title and you get IT four percent well god is carbon dioxide and Stimpson we'll go as water so he is the
answer then to my big fat question ID four percent fat is X. how'd sixty percent scribd is Warda somehow can be you're running face the sweat and that means that ten kilograms of fat becomes I point four kilograms of invisible gas that you breathe out that's amazing every time you were doing some exercise and your breathing right guys up you're losing more white than when you
