Refrigeration | SciShow Tangents Podcast

In this not-so-chill episode, everybody gets a little unsettled by the concepts around refrigeration. Quantum computers, thermoacoustics, molecular chemistry, elephants, the phantom letter "d" that gets added to the shortening of refrigeration...it's all just. So much.

re fridgerarion is simply the control of entropy

[@nottsork]

on the subject of spelling , TUCKSON (tuscon vs Tucson) is spelt WRONG , you have a typo in your own town name , No where in the elnglish speaking world does and S sound get produced by the letters CS instead of SC

Hank finding out about frozen lasagnas is wild. 7:15

[@MoPaTography]

Give it up for Ceri's cat wandering in the background 🐈‍⬛

[@ocupersgmail]

OMG A CAT! I AM SO EXCITED TO FIND THAT CAT (just started watching the podcast)

[@StarSong936]

People have told me all my life, "Don't make waves." Turns out, you should make waves. The problem come in trying to figure out the right kind of waves.

[@photovincent]

nobody thinking of a duckling as least scary? This did remind me of the time I was camping and woke up in the dark with an unknown animal with me in the tent. turned out to be a small kitten, so close to perfect!

[@Bluesmudge]

We need a scishow tangents poetry book! I am going to keep commenting on the new videos until it becomes reality. I will manifest my preferred destiny!!

[@Challkboard]

WooHoo!! So excited for Ceri!! I NEVER would’ve guessed that you were 36, Sam!!

[@michaelpytel3280]

The oldest thing in my freezer is Kodak film from the '90's .

[@kelsqi-books4835]

Lol hank just apparently hasn't ever registered the "family meals" freezer section. They sell those huge frozen lasagnas at kroger, walmart, ect.. they're just not always right next to thw single portions 😂 he could order a huge fresh lasagna from Olive Garden if he wants it not frozen 😂

[@jamesdriscoll_tmp1515]

Nina's has lasagna trays, to go, ready to serve. But I prefer their calzone. Hang out in the bar while it bakes :)

[@CactusMuffin]

Honestly the least scary animal to have in my bead would be a spider because at this point I just expect them to be everywhere.

[@jerryfick613]

Rv fridges can be run conventionally with electricity powering the compressor. They can also be run off grid using propane. The refrigerant is heated by a propane burner to evaporation, then allowed to condense, removing heat from inside the fridge box. Propane fired refrigerators have been used for decades and work really well. P.S. Thermo acoustic refigeration requires helium. There are limited sources of industrial helium, it is also difficult to perpetually trap helium, it is so light, it tends to escape over time. So production scale accoustic refrigeration would require material improvement, either in the refrigerant used or the infrastructure to hold the heluim.

[@SassySlayer69]

I love this podcast so much! I’ve been listening for a long time, and let me just say this: even if this show doesn’t get a *ton* of views, please don’t end it just because of that 🙏 There are lots of us out there that appreciate the love and passion you put into this project, and look forward to each and every new episode! So, with that being said, this was another lovely episode 😊 Sending love from PA ❤

3 adds with a KZbin ad in the middle of them. I’m glad people want to advertise with you but I liked it best when there was just one KZbin ad.

[@sumusubique]

I am standing by my conviction that the least scary animal is a hermit crab.

[@theswiv]

"There's a human that gets it, and that's cool " Love it ❤

[@alangriffin8146]

Around 14 min is a really great explanation of air conditioning

[@leosteinmetz]

I used to work in a lab that used a bunch of thermoacoustic refrigerators, and we also used a bunch of other cool and bizarre physics-magic equipment (like "adiabatic demagnetization refrigerators", which use magnets to cool stuff down, and "transition edge sensor bolometers", incredibly precise thermometers using superconductors). The lab was full of physics PhD students and postdocs and a couple professors and they could effectively explain anything in the lab, which was full of incredibly complicated processes and equipment, EXCEPT the thermoacoustic refrigerators. Absolutely no one in the lab understood how the hell they actually worked, but they did a great job of cooling our fancy equipment down to 4 Kelvin. Sam's explanation was as good as anybody in that lab would have been able to do, maybe better.

[@organicsugarcones3397]

I feel like waking up with a puppy or kitten in my bed would scare me in that a) first touch: is this a rat? b) after seeing what they are: are there more of you and am I lying on any of them and killing them? and c) do I have to take care of you now? I think based off of where I live (Hawaii) a gecko would be the least scary/troubling thing to wake up to, though it would probably startle me initially, because I could just put it on the floor and go back to sleep. A cute friend that I don't have to take care of, that keeps pests away. A+ animal

[@aeroscorpian]

Giggle moment: I have a business that heavily uses Lego, and I was looking through minifigures when listening to the segment mentioning Lego. Made my nerd heart happy. 😊💜

[@Conus426]

awesome episode as always guys. refridgeration is one of those things that has always existed as something that i didnt care about and or thought it was too complicated for me to try and learn anything about, so this was quite interesting

[@jackielinde7568]

It's funny how you're talking about not being afraid of dogs and how you totally can win against them in a fight. And yet, they are the number one killer of humans compared to all animals in the world. They kill more humans than sharks, rhinos, lions, tigers, and hippos combined. To be fair, part of the death toll is from rabies. I think it's a third of the dog kills.

[@markedis5902]

How long will it be before we have quantum processors in smartphones? My Samsung S22 has a neural net section on the Exynos chip to help with voice recognition and optical image processing. I was born in the late sixties and it’s my generation that brought the internet to the world, what’s next?

[@kari-gs4eq]

The oldest thing in my freezer is rennet for cheesemaking

[@flowersandeverythingelse2369]

This is such a lovely episode, I had a lot of fun listening to it. Thank you!!

[@muhmuhmonahan4919]

I guess Hank has never been to a grocery store before.

[@CatBarefield]

FRIDGIDAIRE COMES FROM FRIGID AIR?!?!?!?! Are. you. shitting me. I didnt speak english at home growing up but its wild that it took me so long to hear that brand’s name pronounced correctly. Woahhh

[@reinq_5584]

Ah.. calorimeters.. thermochemistry.... Was my Achilles's Heels😭 glad I kinda get the hang of the basics thanks to Crash course and my very VERY patient chem teacher

[@dixon_481]

I'd have picked Ceri's fact... The idea of being able to 3D print high quality insulation for housing, especially in developing countries, is amazing!

[@jamieoglethorpe]

You really need to do a SciShow program on the JWST's sunshield and how it passively cools to cryogenic temperatures. There is a cool article on the NASA site explaining it in detail. Dustin from Smarter Every Day had a really cool show of his dad measuring the shape of the sunshield. The exact shape of each layer is critical.

[@Challkboard]

I would be terrified that I would kill the puppy; And simultaneously incredibly confused & concerned about how it got into my apt. and up into my my bed 😂

[@athanatic]

Consonant softening ("frig" "fridge") is common in spoken languages documented at least to several recensions of ancient Greek (e.g. hard 'b' versus the 'v' sound in modern.)

[@frogz]

why does hank have a random metal halide bulb on his shelf? .....i guess probably the same reason i have a random box of arc lamps

[@pamelasmith7740]

I had a mini sd card go through the washing machine and work just fine.

[@finmand1338]

We're not as individuals ready for what we've wrought as a species let alone what's coming with artificial consciousness soon to be from A.I. and the technology currently tearing us apart.

[@LawTaranis]

You guys should reject all ai sponsors... They are really problematic.

[@heatheredwards2982]

Always make sure you chill your foods (that aren't prefrozen) in the fridge before you froze it to help prevent freezer burn and large ice crystal damage.

[@empichel5690]

I've seen big lasagna at the Safeway! Never checked Montana Safeway though

[@mckinleyt98]

i’d say that “what animal are you least scared of” and “what is the least scary animal to find in your bed” are extremely different questions if we factor in how they got there!! if there were like a bat in my bed that’d be really scary but i’d just be like “oh i left the window open” and move along. if there were a corgi puppy in my bed that would not be inherently scary but it would imply that a human person had come into my house and put it there 🙃

[@southron_d1349]

I suppose the description of a Coolgardie Safe was too obviously a kind of fridge.

[@wnedyb.kellie2371]

I love to buy the giant chilled lasagnes. I brought one to my friend’s birthday party because she is the lasagne princess

[@LawTaranis]

Can we talk about the social media coordinator's nickname being the most accurate thing in the universe?

[@Werd2jaH]

Hank and the science couch: what came first? The stone? The fruit? (Lime) why do they share the same name? Thanks.

[@epsilonaut]

If you leave a glass of water on the bedside table for a few days, it tastes the same as melted ice. My guess is that it's due to dissolved gasses - if you pour either of these liquids from one vessel to another, they taste of normal water. I think the increased surface area of the flowing liquid allows better gas exchange.

[@shrededpudding5921]

hank describing half of a heat absorption refrigeration system in the second question but having no idea was genuinely hilarious. lithium bromide and water is the refrigerant used in these systems, along with a waste heat input. its why they are potentially really efficient for server farms where there is a ton of waste heat already.

[@inrevenant]

I wish I hadn't listened to the opening segment right before bed, what, with all the talk of dust mites and nematodes and... 😅

[@ZedaZ80]

Things I learned: Legos are... >_>

[@user-li9vt5mi2n]

Sam, one of your fact off facts was literally fish that could jump out water and impale your face and heart lol something to be afraid of haha

[@thekathleenab]

A domestic bunny is less scary, still small, soft, and cute, and less likely to bite than a puppy or kitten

[@robnol84]

8:17 we have a food place here where I live that does this. They cook meals and refrigerate them. Then you buy them take them home and pop them in the oven and then you serve it.

[@wnedyb.kellie2371]

I am least scared of blackbirds because I am instead mad at them for eating my apricots.

[@theperfectbotsteve4916]

like a single ant wouldn't be that scary in a bed it might be concerning but not scary

[@KY_CPA]

8:31 can confirm that it's possible to buy large lasagnas at Sam's Club. I'm allergic to beef, so I can even find premade family size sausage lasagna at various grocery stores sometimes. In fact we just had it last night and the leftovers are in my fridge right now 🤤

[@unicornep1818]

Cat Moves, so cool, now what were you talking about? Pip pip

[@osmia]

Can't you make ammonia from letting your pee sit out in a pot for a few days?

[@Mithrandir39]

Sounds like M&Ms in Canada. (not the candy)

[@epsilonaut]

In space, no one can hear you thermoacoustic refrigerate.

[@shrededpudding5921]

A really good way to understand refrigeration better is to map out a comfort cooling system on an entropy graph for r410a. it makes it much easier to see the connection between pressures and temperatures. fun fact: many refrigerants decompose into phosgene or flurophosgene when exposed to high temperatures! how neat is that?

[@shrededpudding5921]

It was really interesting seeing a perspective on the industry I work in from science communicators. Trying to explain what is going on in refrigeration without all the handy examples we have is no small task. the water bottle analogy is the perfect way to start to understand the concept because it really helps understand the sensible/latent heat difference.

[@Savalanoghlu]

Is business so bad that you need 3 sponsers?!

[@guij666]

refrigerator being shortened to fridge with a d has always bothered me, too!! where does the d come from!!!!!

[@clarabisson7299]

1920s: abbreviation, probably influenced by the proprietary name Frigidaire . that is oxford english dictionary, I also have always just assumed this. they did say in the video Mariam Webster has a different possible reason which seems more complex to me the word frigid also just exists

[@skinwalker3953]

What does old water taste like ? :I

[@Challkboard]

Me realizing around the 9:00 minute mark that this is, in fact, *not* a live premiere 🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️ Sorry everyone!!

[@Lesserthannone]

Sam if you want to win Sci Show Tan, just do deep tangentail dives into JWST tech! Every week its David v the Golioth of Ceris life long dedcation to the sciences, Im always like Cmon Sam me boy you can do it lol!

[@lyledal]

I'm very concerned that no one seems curious about why all of these animals are just randomly showing up in their beds while they sleep!

[@osmia]

Looking forward to finding out what the oldest thing in Sam's freezer is
