[@Challkboard]

I’m so glad you didn’t cut that Sam!!

[@Campfire_Bandit]

[@metaknightmare1234]

John not closing the door when he left is peak sibling energy that's how you know they're real brothers 😆🤭

[@lutilda]

Glad Hank felt good enough to record this day! ❤ Hope you have many more days like this one.

[@KY_CPA]

So THAT'S why John said in his video last week that he knew Hank had prerecorded a Tangents episode 😂 Glad we got to see/hear the sibling interjections

[@alexisatuatara570]

The needlefish fact was great lol. I know someone who got stabbed by one, at night, while pointing a light at them. He was diving with someone who was nervous cause there were a bunch of them jumping out of the water, so he pointed a flashlight at them to show that they weren’t dangerous…. and was promptly stabbed in the neck

[@sidoniegabrielle269]

lmao this sounds like my dad in like a dozen different situations. very knowledgeable person but having a very "hold my beer and watch this" moment

[@OneBentMonkey]

Like a baseball going 50 mph is now the gold standard to judge all other impacts and I’m here for it! ❤ 😂

[@kaitlynoddie9649]

ceri's hair is so good in this episode i'm jealous

[@Tosslehoffe]

looks like it's just viral colorditioner.

[@jessicatiedeman1065]

I love how much Hank adores you Ceri and Sam. Its so heartwarming to see. What a sweet episode. I'm thankful for the video version of the show especially for that beginning 😊

[@robhacklblumstein]

I love that you talked about linguistic relics like "godspeed" and "by Jove" because with the discontinuation of the iPod in 2022, "podcast" is officially also one of those!

[@LillyWhit2LsAndAnY]

Haaaaank!!! And also John cameos! Love it!

[@susanmonroemcgrath]

I love the dual poems!! (This should maybe be a new feature)

[@jankies007]

I second this!

[@Pannekoek.]

Most people can't even survive 1G for more than 85 years

[@lark613]

Sam, that fact had my jaw on the floor. Great work!

[@MossyBear]

"Godspeed" is not something I've used to mean "go fast," but more like "good luck," but I've never thought of why. Thanks for that mind blowing factoid

[@pinkvulpineproductions3463]

I love when we get multiple science poems. You can never have too many science poems.

[@Tinyvalkyrie410]

I saw a school of very large needle fish while snorkeling in Hawaii as a kid, and the crazy thing was they were rapidly changing colors and patterns. They would instantly flash between silver, black, striped and spots. I reported this to my family, none of whom believed me, so I forced my father to come out with me, relocate them, and then follow them until they repeated behavior. The shock on my father’s face and my insanely high levels of smug satisfaction is genuinely one of my greatest memories from childhood. We go to Hawai’i most summers, and I have only seen them once.

[@tjthrash0143]

Hey i know this one! Speed is the rate at which object a is moving in relation to object b. Yay me mart!

[@sueg2658]

We LOVE you big brained buds. Well wishes Hank. 🤘🏻♥️

[@TheOnyxFlame]

@28:39 Hank notices the synchronized **pew pews**

[@empichel5690]

Sam said in a previous episode he has an idea for John as a guest. I'd watch that!

[@thecrazyastrogirl]

The way that Sam talks about his little brother is so cute

[@bradbeard4329]

Glad to see this back, as well as Hank feeling good enough to do one! Hope you are truly doing well!

[@jankies007]

LOVE TO SEE YOU ALL TOGETHER 💙💙 I think I will never stop watching and enjoying this podcast as I grow. These guys all are an absolute joy to watch/listen to. And all of them are top inspirations for me (as far as "public figures"/internet people go, alongside snake discovery's emily and ed, overly sarcastic profuctions, and some other I can't find off the top of my head:"D) Started listening to this back in late 2021/early 2022. Currently I'm at 18, and who knows maybe I'll still be here until I'm over 50😊

[@sylvy16]

i also love osp. also the misspelling is making me laugh.

[@jankies007]

@@sylvy16 Just re read this😭 sorry you have to see all the typos lol To be fair, it is currently 4 a.m. where I live, and I have been /procrastinating/ to do work for the past 10 hours😢 the worst part is I am not even sleepy anymore. I just hope I'll manage to get myself focused by 1 p.m. since I have two back to back meetings that I am quite unprepraed for😭 wish me luck, I guess..🙃

[@ethan-loves]

is it normal to have a crush on all three tangents hosts simultaneously? ... asking for a friend 🤭

[@muhmuhmonahan4919]

I laughed SO HARD watching Top Gun Maverick when he went 10G. My spouse was so irritated.

[@muhmuhmonahan4919]

It's so unfair that John's there, but not a participating guest.

[@SteveRobinsonMKE]

So great to see Hank today!!!

[@julescaru8591]

Nice fact Sam ! And those little sh:t shooters lol, love the show ! All the best Jules 👏

[@IceMetalPunk]

I was trying to compliment the idea of Ceri and her sister making a gaming channel, but apparently certain words trigger KZbin's auto-moderation to delete the comment every time under the assumption it's spam. Damn invalid heuristics! *shakes fist* Anyway, I think it's a good idea, and have now avoided the words I believe trigger the deletion bot... hopefully this comment stays up!

[@xpndblhero5170]

40:00 - I remember this story and he was more than bruised and shaken, the G-force literally pulled the cornea from his eyes and his legs were bruised and he had burst blood vessels all over his face... That was an insane experiment and the footage is equally as crazy, I suggest looking it up because it's crazy they even put a human on that sled. SMH

[@AlturiigosWritingBlockBlogspot]

For how fast a human can safely go, I feel like two considerations are the medium and or method of locomotion. If you had super-speed, how fast before air resistance became harmful? Based on the required forces to move the body, what's the limit of force the legs can output before it starts to hurt the muscles and joints?

[@Rufflesandrage]

When i saw John pop in i was hoping for a moment that he would critique or read the science poems, but that would be a lot of pressure. Maybe one day he will be a guest author.

[@viviangunsettcecco]

Godspeed to you all!

[@shadebug]

So back when the first speed limit was broken cars were supposed to have a person walking in front of them to inform people of the very dangerous machine hurtling towards them. Presumably the real problem with going at 8mph was the person not being in front

[@heavymetalbassist5]

Hey look its both those green boys together ❤️

[@DeliveryMcGee]

Re: Ceri's explanation of Gs toward the end: It's not the fall that kills you, it's the sudden stop at the end. Pretty sure Stapp got a detached retina from that 46-ish G record, fighter pilots tend to black out at 10G.

[@DeliveryMcGee]

But that 10G sustained turn is one thing, Stapp and car wreck victims, and racecar drivers, proved you can survive WAY more than that instantaneous (if properly tied down*), and probably won't remember the trauma. (*at some point eyes-forward deceleration makes your head pop off like Rock 'Em Sock 'Em Robots if you don't have a HANS, see Dale Sr. of NASCAR fame)

[@stuck_around]

ceri i love your hair !!!!

[@riannadixon1083]

this makes me so happy

[@susannahallanic1167]

OMG!!!! My Citroen monAmi 100% Electric is faster than the Los Angeles Class Attack Submarines! The monAMI is 4.961mph faster than an LA Class Attack Submarine! I bet it is heck of a lot cheap to build and run also. WOOT! Y'all made my day! Thanks!

[@terranovarubacha5473]

Why not combine these facts? They're both so good and would go so well together

[@BaddeGrasse]

I would 100% watch a Sam & Wilbur Play Games

[@SnarkNSass]

Halfway through ❤😂

[@markedis5902]

Definitions speed = distance / time. distance = speed x time. time = distanance / speed

[@kassywilson7292]

I thought "God speed" was usually used to mean something closer to "travel Safely"

[@Times365up]

Hank! My man of fortune. Question: When our mother Earth works the mojo (gravity) how come it doesn't affect the weight😊 scale?

[@rautikd]

Lovely poem

[@thenuttynerd2331]

Dumb question here, but why don't we care about direction when talking about speed?... a ball traveling in an arc travels significantly further vertically than horizontally in the same amount of time so the ball is traveling faster vertically than horizontally which in my brain means direction does matter when talking about speed... again this is probably a dumb question and I'm just missing something super basic... I'd appreciate it if anyone could help me fill the gap in my understanding. Thanks!

[@davidenzler1691]

Velocity exists when you care about speed and direction. Speed is just a another tool/value that can be used when you dont need something more complex like velocity. If you want to know the distance you traveled in a straight line, then speed and time are sufficient. However, if like in your example, you're looking at the path of a ball in arc, then direction is important! But you would use velocity which is usually represented as both speed and an angle relative to some plane.

[@thomaswade3072]

The constable had to catch up to the 8mph in 5 miles, that means the bike was moving more like 13+

[@billyalarie929]

Who else was hoping for a Godspeed you Black Emperor reference, just once?

[@bananatassium7009]

john cameo!!!!

[@DeliveryMcGee]

John is best big bro.

[@stellyz397]

Hi John! 👋

[@richardreardon9948]

Walter Arnold was fined one shilling which adjusted for inflation is £5.47 or about $7.00.

[@Challkboard]

AHHHH!!!

[@AllTheArtsy]

okay John should have been mic'd for the episode hahahaha

[@lizsteilkie]

Couldnt find yall on peoples choice awards nominations?

[@alexwhattam547]

Did Sam get a cardboard cutout Smokey the Bear after they talked about how hot he was? iconic behaviour

[@Hiddenreader]

I just watched that episode and it was already there 😂

[@janusatthegate6201]

I thought godspeed meant go in safety.

[@tomlewis4205]

❤❤❤😎👍

[@ExoticTerrain]

🙋‍♀️

[@markedis5902]

Breaking news!!! Jumping Needlefish hit by high energy cosmic ray

[@arthursamuel301]

I will google the gross needlefish photos AFTER i finish my meal

[@AidanRatnage]

Why does Hank not have time off for his cancer?

[@Rufflesandrage]

The dftba krewe and John encouraged him to take any time he needed and he did a whole video about how he wanted to continue to do anything that brings him joy whenever he feels well enough to. It's been hilarious and oddly inspiring following John take over as CEO of complexly and everything else

[@fairygurl9269]

"Learn to Walk Without Moving" *DrAlok Kanojia Healthy Gamer GG 💞

[@unicornep1818]

Can we have an episode about CATS. Inky is cool and I think everyone has a cat. Not enough Inky in the last couple of epoisodes. Pip pip

[@janusatthegate6201]

Research subs need also to be quiet.

[@urpalval88]

I'm 666 like 😮

[@picklesdill5462]

Hank your bro creeps me out. I know you can beat cancer. :)
