My PhD Thesis is Due. We’re making ice cream

hello welcome back to explosions and fire the YouTube channel where we do chemistry today we're not really doing chemistry the chemistry has not been working well for me I'll say that it hasn't been working well none of my reactions are working I even traveled for YouTube It's the ocean and that was really exciting to go see some other people do some chemistry and even that didn't work for them look at it it's beautiful definitely feels threatening probably because I was there unfortunately we will not be launching is it because I ruined things yes it is actually it was very very timely you might be thinking so what your reactions never work so what what's changed how is this any different than usual you are correct things do never work but usually I have more tolerance for them I have been doing a PhD for as long as I can remember at this point it is due I mean it's been due for months but I need to actually do it I'm not very good at it um yeah so anyway I was in Audi which if you don't know what Audi is it's kind of like a batik Australian Bodega they were selling ice cream machines and it occurred to me that maybe I could feel Joy so that's what we're going to be doing I could be riding this right now I cannot stress this enough

I'll be honest I've always wanted an ice cream machine not just because I [ __ ] live off sugar but also I wanted to try out a thing I saw on Reddit years ago which is never a good way to end a sentence I just saw it on Reddit a few years ago and I wanted to try it out because you know that post was not made by a sane human being anyway this Reddit post gave me an idea to make ice cream that was statistically unpopular yet still good this post went and looked at recipe. com and all the spice combination so we have data here that tells us what spices are the least likely to be used together that doesn't mean they're bad I mean it kind of implies that they're bad but they could be good because I feel like it's easy to make good ice cream using popular ingredients and I feel like it's easy to make terrible ice cream using unpopular ingredients for example when unpopular spice might be Benzene and I could make you Benzene flavored ice cream and tell you that Benzene is back but that's not particularly good ice cream that's just unpopular and bad ice cream but can we make unpopular and good ice cream

might not be a challenge for everyone else this is a challenge for me because I'm not actually very good at cooking so we do need to run through some good ice cream flavors first we're going to get out our measuring cylinder and we're going to put about 120 ml of milk and 120 ml of full cream in there and mix them together to make 150 full cream milk and then we're going to use three egg yolks which is potentially less egg yolks than other recipes might use but first of all eggs are expensive and second just weird man like have you ever really thought about eggs I mean are we honestly gonna say that's normal is this normal and then we need a whole lot of sugar I think it's about 75 grams which is a whole lot of sugar but we'll pretend not to really think about it we need to add the sugar to the egg yolks and then we're going to beat it until we start to get stiff and then we add in the milk and mix it all together and that's basically done this uses raw egg yolks in the mix which apparently is fine in Australia according to Big Egg well no they didn't really say it's fine they said you need to pasteurizer which you can do you can like heat the milk up and add it and pasteurizes the Egg but you can also just gamble with salmonella Big Egg says it's it's probably fine now we have our mixture we can add it into the ice cream machine and we've added a bit of vanilla Essence so it's really not too bad in fact it's quite nice it's quite nice and we can really add any good flavor to this ice cream and it will turn out good for example honey and chocolate syrupy stuff you know get honey and chocolate syrup ice cream it's pretty good that's called Damn Delicious we can go to the local maccas and blend up a hamburger with some milk and put it in the ice cream and you know it's really not that bad we can get a can of that sugar-free Monster Energy drink and just boil it down until it's some sort of concentrated mess and then add that directly into our mix and it's I mean it's nearly okay honestly oh eight cans of Monster Energy at the same time with a hint of like off milk at the end it's like a solid seven out of ten I mean don't tell my family this but I've been really getting into the energy drinks again it's embarrassing actually I wish I was a coffee person I could just go around and be like yes don't talk to me till I've had my sixth morning cough instead I'm like I'm a monster boy don't talk to me till I've had my morning heart palpitation sponsored content they should invent an energy drink that I'm not embarrassed to drink in public I think that would sell really well sorry I'm gonna pull this back up I took a quick break to write like a paragraph on my thesis that was a fun couple of days anyway the Reddit post

okay the Reddit post important so The Mastermind behind this Reddit post made the mistake of posting his hard work to the subreddit r slash data is beautiful so of course all the comments are just complaining about the color scale okay guys we get it if you think old data should be beautiful I had this issue with my thesis doing a thesis you've got to choose a color scale I guess I've got [ __ ] tons of data I took a very normal person approach to picking a color scale for my thesis I just watched a 30 minute video of why jet the red blue color scale is actually the worst color scale and the best color scale is this one called veridus which is like a purpley green and I watched the whole video and I just posted a poll on Twitter which color scale to use and people selected yet so I just use jet for my whole thesis if you're my supervisor watching I chose jet because it highlights the data better not because of the Twitter poll anyway the comments successfully bullied this guy into to reposting the data which okay I will admit is a better post still a little bit confusingly plotted but we can see which of the spices are at least correlated with each other so for our challenge we're going to choose five of the least popular combinations from this new updated bloody post here let's make some ice

cream vanilla black pepper I think has the best chance of working out of the five that I've selected I really wanted to go all out on this one I wanted to make a really nice vanilla so I got vanilla bean a stewed the vanilla bean in with the milk I even got some vanilla sugar which has got some vanillin in it it's the chemical that it tastes like vanilla it's like vanilla on vanilla and it makes by itself a really fantastic ice cream the vanilla kind of brings out the creaminess I'm not really making Leaps and Bounds here it's vanilla ice cream of course it's good it's like me riding my bloody thesis I'm just telling you things you already know we could just grind up some black pepper into our vanilla mix it looks really good because it's got all those little black flecks in it which are kind of like as if I've used really nice fresh vanilla bean it's got all these flecks in it but then when you eat it it's just not so good takes like a really gritty vanilla apparently get the pepper until one at the end it's just not very good like this but I think there's still promise instead of just doing the vanilla bean with the milk I added some black peppercorns as well and let that stew for a while what I really want is I want the spiciness of the pepper to come through not like a heat like a capsaicin but what's the chemical this is a chemistry Channel Pepper's got a chemical you can make MDMA from it after we've got all the flavor out we can strain off the peppercorns because I'm not putting whole peppercorns into an ice cream because that's just asking for a tooth to be broken and I spent too much money on goddamn braces that vanilla and the pepper don't really complement each other I mean of course why would they but they kind of fight against each other you've kind of got this cooling nicety from the vanilla but that kind of sharpness from the pepper and cancel each other out in a way that kind of makes neither of them better it's not a bad flavor but it's not a very good pairing six out of ten is that too generous

and I'll be honest this one is never going to work we're just going to take our beautiful vanilla ice cream mixture and add a little bit of garlic powder to it and it looks good it just [ __ ] is bad that's [ __ ] disgusting that's fun that's genuinely [ __ ] I mean Galaxy good flavor it's just it doesn't combine at all well with the vanilla that's such a [ __ ] combination of flavors this gets a I don't know it's [ __ ] horrendous it gets a two

cinnamon and pepper are both really Punchy flavors so I can't really see them working very well as a combination which is probably why they're not very popular but we're just going to Stew our milk with some cinnamon sticks and some whole peppercorns and just let it stew for a while I mean we really want those flavors to get into the milk and I guess why it's stewing I really should answer some questions about my PhD because people comment and ask things about my PhD and I really don't address them Rapid Fire Let's answer some questions about my pear tree what is my PhD on building a setup that uses tunable lasers a type of laser called Optical parametric oscillators and we use them in a new way to try and do some sensing that doesn't sound like chemistry I'd hate to come across as a con person but my PhD is not actually in chemistry um it's in physics I'm a physician physicist that's the word [ __ ] I forgot what the word for my thing is but in my defense I did only find that out like a year into my PhD the project is basically physical chemistry because I did undergrad and the year after undergrad which is called honors in Australia all of that was in chemistry so I just assumed I would be doing chemistry as a PhD my professor just mentioned in passing like a year into it no I definitely put you in for physics so whoops um I'm assuming at the end of the PHD you do a thesis defense can people watch that thesis defense like most universities in Australia thesis defense is not part of the curriculum here I don't have to do a thesis defense the assessment is a hundred percent written word baby it's all in the thesis I don't even have to do a private defense no defense it's pure thesis attack all right I assume people can read your thesis once it's fully submitted no you can't read my thesis not just because I hate it and it's boring it's getting embargoed two years after it gets accepted it doesn't get published online it's just IP agreement [ __ ] because it got funded by a third party sort of thing and so they have IP rights I don't own any of the IP that I've generated over the last five years at University so I don't even know if I'm allowed to talk about it which is just absurd really like it's fun to complain about the PHD and it has been a bit of a grind but I've enjoyed it I don't feel like my time has been wasted and on a day-to-day basis it is fun does that make a PhD sound appealing I hope it doesn't so yeah I make YouTube videos to forget about what I'm doing at University so I'm not going to make a video about what I do at University because of Ip things and also it's just boring all right does that answer all the questions you have about my PhD probably not but importantly what's the ice cream flavor taste like oh it's unbearable it tastes like all the bad things about getting punched and none of the good things see I mean this is worth the wait this is content we've got another flavor let's do another I'm not going to be a hater

here I think this is potential parsley is this nice wide flavor and Cinnamon's this pointy flavor does that make any sense we're going to use a lot less cinnamon than we did last time because that was just way too much cinnamon and we've got to make the parsley milk which is really a little bit disturbing actually I don't know this fills all little Savory and we'll just add lots of sugar and it goes from being a Savory dish to it to a dessert enough sugar right this subtle green with these little nice little green flecks through it it's quite visually appealing so we've got that going for it foreign it's not good but it's not that bad I was not mentally prepared for this not to be awful kind of refreshingly earthy I wouldn't get this again I would not make this again but maybe I've got to eat more parsley you know I gotta look into these fresh herb things and [ __ ] vegetables

vegetables much like chapter 7 of my thesis I'm worried that this n section will be so bad that it will make you question why we did any of this work at all do you know we're here anyway so we've got Ginger and oregano surely everyone agrees with here but I [ __ ] hate Ginger is awful and it's relatable in the fact that it's everyone's least favorite route however we can get dessert type Ginger it is coated in chocolate it's still pieces of real Ginger so we can put that in our ice cream the same cannot be said about oregano is the least deserty herb spice thing and look there's no surprises here this ice cream is genuinely rank oh that's a weird one

all right I feel like we've achieved something today I don't know what but I feel like we've achieved something and that was the point of this video so I think we're good and I feel like I've complained about my PhD enough that you're ready for the punchline you ready for this punchline you ready I've already started the post like project and helping someone else with their PHD I'm part of the academic system now baby the cycle continues forever more chemistry videos coming soon
