In general this seemed kinda odd. The whole kid explanation didn't feel like an explanation at all. Kid knew some basic stuff and had some questions, then the guy's like "yo how do dolphins sleep, do you wanna know, do you?". If someone can write down 3 short sentences and that encompasses all the discussion got you, then that's a waste of time, even for the kid.

[@justhurderr8515]

@@dowfreak7 it's not a waste of time, a brain of a kid really sees that as pretty interesting, myself included when i was that kid's age i would get exited to know about how animals sleep, eat or do stuff, because knowledge when you're a kid ITS THE MOST INTERESTING THING EVER, now why dude fill up a balloon for the teeneger? simple it makes the person pay more attention, that's why a lot of university lab professors, use stuff and not just theory !

Kids are scary

[@registeredjopper]

It’s something I’m learning over the course of completing my PhD. Once you get to a certain level of understanding of a subject, it becomes harder to “dumb down” explanations because you become so accustomed to certain terminologies etc. You spend all day thinking about this subject at a level of such complexity that trying to explain the basics (or, god forbid, those aforementioned complexities) in layman’s terms is really daunting. Unless you’re experienced in education. That’s probs why teaching STEM subjects is a whole degree field in itself.

[@nairabittencourt6125]

@@registeredjopper that's what makes someone a true expert: being able to explain their subject to someone outside their field.

[@registeredjopper]

@@nairabittencourt6125 I don’t really think that’s the case. Someone can absolutely be an expert, a master of their field, but simply lack the communication skills to explain the subject at a level that people uneducated in that subject can understand. It doesn’t mean they’re less knowledgeable or experienced, just that they can’t really relay that knowledge in a digestible way for normal people. Not everyone can.

[@nairabittencourt6125]

[@zin82e98]

His tone even changed- he did not like her 😂

[@matheuslopes8832]

Omg he clearly speaks like he doesn’t like her hahahhaha

[@WordyGirl90]

She asked a good question on the effects of amphetamines and he got pissed because he didn’t know the answer. Lol.

[@twiceseventeen]

This guy is the best at explaining at all five levels. Too many speakers here make it complex for level 1 and level 2.

[@jinsum5449]

nothing like listening to how sleep works while trying to fall asleep

[@thefintechking]

18:00 She basically said, "you didn't teach me anything I didn't already know"

[@Draftmaker]

Not true.

[@HexerPsy]

Here's what I noticed. When the teacher is listening to stuff he already knows, he stares and his head doesnt bob. When he s in conversation with a peer and looking to drive the conversation, he nods endlessly.

[@ixl911ixl]

HexerPsy hahah. Going back watching him bobble his head like a maniac with his final guest is hilarious, thanks for pointing this out.

[@hannahkay396]

i love how excited he is about the topic

[@gelfjunga9257]

this man is so good he can explain things nicely

[@thematchkookieisholdingins5542]

Me: watching this instead of sleeping. The sleep scientist: "am I a joke to you?"

[@m.a.3322]

I surprised myself when I understood most of the jargon he was talking about... then I remembered, I'm a medical student 🤨

[@juliashireen6195]

🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣👍👍👍👍👍👍👍

[@thifanny7298]

I was like "yeah finally one where I won't get lost on the last levels" And the conversation with the specialist was so insteresting

[@patrickmorency]

Don’t worry, you’ll forget it all in residency

[@Muhamedim]

@@patrickmorency LOL so true

[@SR-er8sd]

lmao, psychology major and SAME

[@mythirdchannel]

I like this guy :D I think he did a good job on all levels of conversation, and I learned new stuff too! :D

[@AtlasNL]

Very interesting stuff to learn at 4:00 while not being able to sleep Edit: Also this man wears a fabulous pair of socks

[@megami7373]

this five level series is so pure and refreshing to watch.

[@krazekode]

The high school student looks like he's in some real need for sleep

[@crystalllllll]

He's getting 6 hour naps

[@bulldozer8950]

Crystal Zavala but is he actually sleeping or is everything a nap....

[@guidestone1392]

I remember not getting enough sleep in high school.

[@Zones33]

We all do

[@pascoto]

Wait until they get to university/college lol

[@centaurk5603]

It's interesting. I have heard that you will go through periods of being tired, which I personally agree with. Once you surpass a level of being very tired, you will become less tired and then go through the cycle without sleeping. Also that naps can be useful, but not long naps. Because apparently catching up on sleep is actually something we can do. If we got less sleep the previous night, we can sleep more to :catch up"

[@rosemaley1668]

We needs this series back.

[@SageROSA42]

I learned more with the kid than I did with the expert.

[@maximvasilleyvich6060]

JustSharin' it's because you're a lay-person. He explained it in a way so that people who are not so scientifically inclined can understand

[@sam-solo]

The expert was basically saying sleep apnea and/or sleep disturbances can cause a super large increase in the chance you get dementia or alzheimers or Parkinson's in old age based on her studies.

[@humphryshan9494]

she's an md phd so she does more research on the clinical aspects of asleep

[@maureenlaneski2802]

I feel like I understood the gravity expert better than the sleep college talk.

[@je6874]

That college student is absolutely stunning

[@juandelarosa1212]

exactly

[@Melancthon7332]

in Hawaii everyone is gorgeous, it's ridiculous

I don't know how he maintains eye contact whilst not fluttering his speech. I'd be sweating if I was him

[@DrVonNostrand]

Her eyes are mesmerizing. She's beautiful.

[@mazzychaz4500]

thanks you guys!

[@kellyl13]

I understood almost everything in this video! This makes feel a bit better after watching the "Musician Explains Harmony" video where I was not quite at the college level. Music, in particular singing, is my favorite pastime, but this is more tailored to my education (BS in psychology, MS in neuroscience, and MPH in biostatistics). Learning how different types of animals sleep was really cool too.

[@kristynahrdlickova891]

As a psychology graduate student, after watching a bunch of these videos about gravity and lasers with knowledge pretty much at the level 1, I’m so happy I can finally follow along with the conversation! 😅

[@user540000]

psychology is super easy

[@MrBladle]

The grad student was really interested in amphetamines...

[@VirulentWalrus]

She was playing with her lips a lot too lol

[@cyanidejack1013]

Me too!

[@DanG626]

👀

[@360.Tapestry]

or that's just one particular aspect that is interesting in her field, given that she has an expert in front of her that she can quiz, and you're reading too much into it. but i'll try to remember where i'm at, too

[@eternalending]

Kryptonite nah, she’s a science PhD student. She’s definitely popping adderall.

[@1207torrie]

Hey I just took an exam all about this last week in my neuropsychology class and I literally knew everything he was talking about. That’s such a good feeling LMAO

[@cathy921ontheradio]

lol my neuropsych exam is in 3 weeks, but I feel you on that XD. Can't believe that talk w/ the expert got me riled up.

[@1207torrie]

cathy921ontheradio good luck!!

[@bulldozer8950]

I have no clue what they were talking about.

[@BLAIDIoriginal]

Congrats!

[@Chonps]

really loved the expert on this one

[@adewati99]

I really love this kind of series, please keep making it ☺😍

Scientist: what's that? (Shows a picture of a 🦛) Kid: A hippo? Scientist: a hippopotamus Kid: OK BOOMER

This comment is one of the funniest things I've seen on KZbin ever.

Made me laugh

But he's not a Boomer?

[@rashmiruby6149]

This is absolutely fascinating!

[@Okguy1_Music]

him: sleep is so critical me watching this video at 1 am

[@JeffSyam]

Whenever they do these 5 levels thing, I always interested in how good the expert when they explaining to children. To me, that shows to us how good their understanding is.

[@danielschoen8402]

But that is the easiest level to explain.. Basically everyone could explain sleep to a child in a simple way. Not everyone could do it at an expert level to an adult.

[@RonaldYengwayo]

@@danielschoen8402 true about everything you are saying, but what l think the dude is trying to say is, you don't know something unless you can simplify it for a laymen to understand.

[@Yeah0bviously]

Seriously, the dolphin's half-sleepy brain thing at the 1st level is way more interesting and complex than the blabla afterwards

[@itpaynesme]

Yeah0bviously it was so fascinating omg

[@TheCactuar124]

That's because you have no idea what he was talking about later on, like most people who watched the video.

[@carbon1675]

Meek omg you said “ok boomer” So funny

[@c0br1tzA]

Yeah, but the last 2 levels are the driving force behind understanding the first 3...

[@Ninjaananas]

I thought it was common knowledge that dolphins sleep like that.

[@sleeptrust-sleepfacts]

This was truly a great idea - super entertaining and interesting.

[@softmusicforsleeping4075]

Thank you, it`s a very great job 😻 This video is so beautiful💜💜💜

[@pookiielover]

You're another level of expert when you're able to explain concepts in multiple levels of difficulty. there are so many people who are good at what they do but they can't teach it for the life of them in simple terms.

[@benrosshirt1477]

"Hippos sleep underwater" Kid: "I could never do that"

[@nithyasreesathyanarayanan5611]

It's pretty cool that the topic becomes more and more focused with application of the knowledge on sleep to various changing external and internal conditions, because that's why they are actually study sleep (which is to give better treatments to people with various disease conditions that may be caused by sleep). It surprised me that inadequate sleep (

The expert’s knowledge is comprehensive

Next I want " 5 levels of level explained."

[@kevinree6461]

Imagine what expert in levels say

[@Exderius]

Great video! Really interesting and in inlightening

[@russellpad]

I found the child explanation most interesting or maybe my brain is in that level only lol

[@paulnikolausmaier7663]

Could you do an episode with an immunologist? Would be awesome

[@OO-gx6he]

I would like to see that

[@comfortlucia]

Yes please!

[@tobithetabby6376]

Especially during the times we are in now
