Cephalopods use jet propulsion of water through their 'siphon' while the 'siphuncle' is used to equalize pressure in the chambers of their shell to regulate buoyancy.
I was watching this, and then it got to the part with the siphuncle at 2:02. There, when I saw the picture, I realized it looked exactly like a little fossil I've had since I was about two and never figured out what it was. Now I know.
1:40 - So, how many inch is 15 cm? - It's almost six, close enough. - No, no, 5.9 is much better, the next digit is a zero anyway. - Oh hell with it, let's go with 5 decimals!
Scishow tells us to point out errors so note that I'm not trying to nitpick, but at 1:40 you state "5.90551 in" to convert 15 cm. Unless you are converting 15.0000 cm (you know the measurement to that precision), then the conversion is wrong. In science you must show your answer to the correct number of significant figures. In this case - 2. The 5.9 in also could have just been called ~6 in, since that is just an approximation for the public to understand. Lovin' Scishow, thanks Hank and everyone!
Thank You so much for all the informative videos. I've been subscribed for quite some time now. Even though I'm pushing 50 yrs old, you are never too old to learn. I will have to watch again to learn how to receive a piece of fossil history & the autograph of Hank Green. Thank You .
I was about to skip an add on a song I was going to listen to on youtube before realizing it was Hank talking about Scishow! It was refreshing seeing an ad that actually is about something I like!
I dug up lots of fossils when I was a kid living in Curtisville Pennsylvania about 100 yards north of Kaufman road & Saxonburg blvd behind a garage that they bulldozed into the hill to put in. That hill is loaded with fossils.
I just recently showed my class the one I have had for years! Might have to get a second one in thanks for you giving me more information to share about these guys. What a helpful (and for me- timely!) vid. Much appreciated.
Dylansgames fossil fighters frontier screwed up the mechanics and some of the designs, but it has a good story and good graphics, and beating the final boss is like playing Russian roulette but the barrel is capable of holding a ton of bullets and you're pointing the gun at something evil and your life and the rest of the world depends on the one bullet being in the correct spot at the correct time
They are quite common on the beaches here in Denmark and I have atleast 50 in my collection that I've found over the years. I love collecting them so I always hunt them down and take the best ones home.
Hey SciShow-guys, this video got me thinking. It would be really cool if you did a series of videos on the different periods og earth, from beginning to present. Of course, this would mean a whole lot of work, but it would also be really, really cool.
Someone has probably already pointed this out, but yeah, they can be seen in practically every step of stone stairs in sweden. If I haven't seen at least a hundred of them in a day, it usually means I stayed home watching scishow all day.
When Hank said that they are really common in Sweden we was not kidding. In my old school here in Sweden we have these big stone stairs in which you can see lots of them. :)
Hey I am an avid fitness buff (no pun intended), and you should do a sci show on how muscles are built, and where the muscle burn comes from when you work out.
I would love to see more geology related scishows! I was excited to see this one because I thought you might touch on how coal was made... But ended up not doing so.
Hank should do a video on zombie science. I know he addressed the complete lack of zombie science on vlogbrothers, but he did a video on Sharknado so I don't think a zombie video would be completely ridiculous.
I collect fossils. You have to really look around to find cheaper ones that are still nice. I just got one for $17 that's pretty decent. I do have some that are several hundred dollars though, but they're super nice.
Hobbits originated in the Valley of Anduin, between Mirkwood and the Misty Mountains. There were three "breeds" of Hobbits: The Harfoots, the most numerous, lived on the lowest slopes of the Misty Mountains and lived in holes dug into the hillsides. The Stoors, the second most numerous, were shorter and stockier and had an affinity for water. They lived on the marshy Gladden Fields. The Fallohides, the least numerous, preferred to live in the woods, and were said to be taller and fairer.
I've just started using the video speed function, and I recommend listening to the outro at various speeds, and listening to Hank at .5 speed because he sounds totally drunk.
Also the upright posture gives an advantage against the sun. (smaller surface area) Aswell as granting us the ability of discovering new grounds for food easier, than if we had to rely on trees to get there.
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on knowledge that has been repeatedly confirmed through observation and experimentation.
I live in Sweden and these are really common here. I've seen loads. I went to live in a cottage in Öland (big island) a summer when i was little. outside the cottage the ground was made out of stone, and these fossils were everywhere.
While I love orthoceras, I have a HUGE thing for ammonites. I've ammonite jewelry, pyritized ammonites, lumpy ones, halves, even one with a layer of ammolite. One of these days I will get a fossilized nautilus, darn it!
I agree that we should all get along, but the doesn't mean that we should ignore the fact that we didn't get along in the past! We have to take historical facts and learn from them if we wish to flourish and grow as a society!
Well, as I already stated more than enough, I can only say either what "we" know somewhat for sure, or what I would assume. In this case it's a mix: Roughly 5 million years ago, our ancestors started walking upright. And we know, that the earliest evidence for an upright posture also came from those parts of the earth, where back then the land was dominated by what we would today call "gallery woods" (Galleriewälder in german - A mix of forest parts, lakeshores and green grasslands.)
Depends on the type, but for the most part its just a normal tesla coil with the drive current controlled with a PWM to create the "pitch". In alot of designs just a simple 555 timer is used as the function generator.
Hank, Do you know Brady from SixtySymbols/Periodic Videos/Numberphile or Destin from SmarterEveryDay and have you talked or tought about a collaboration with them? I know you all have different styles, but I'm not the only one that likes to see you guys working together and how good the content would be.
Archaeopteryx, Aurornis, Australopithecus afarensis, Tiktaalik, Pakicetus, Maiacetus, Dorudon, Megazostrodon, Morganucodon, Haikouichthys, Juramaia, and Djarthia, just to name some good examples.
These shelled creatures raise the interesting question: Has there ever been a mass die-off due to ocean acidity becoming globally unsuitable for shell formation? A great volcanic event might be enough to wipe out animals that relied on shallow waters and a more or less neutral water chemistry.
You see them all the time in Sweden, most marble floors have a couple of them. I don't know if it's the same in the rest of the world. But since marble here are often brown or dark grey, white fossils are easy to spot.
The Ordovician wasn't really a hangover from the Cambrian. Palaeontologists identify a significant event in it called the Great Ordovician Biodiversification Event (GOBE), where life diversified in the next 50 million years or so after the Cambrian, replacing many of the weird forms seen in that period
And, based on the study of the, as you call it, 'survival lottery' of mtDNA, the 'Eve' from which all humans originated existed a mere 6000 years ago. That's a pretty solid blow to evolution's timeline, don't you think?
Swede, here, and I remember the stone floor of my elementary school was packed with those, and trilobites.
Alright now I officially have to visit Sweden!
Im from Sweden and we've got those things EVERYWHERE. I have them in the stone blocks that makes the stairwell of my apartment building....
wow that's amazing!
And here I was, expecting a video about the psychology of why we love the Lord and Saviour, the Helix Fossil.
PRAISE HELIX!!!
+SlayerOfTheBad another helixcian PRAISE DOME !!
First thing I thought of when I clicked on this video
Cephalopods use jet propulsion of water through their 'siphon' while the 'siphuncle' is used to equalize pressure in the chambers of their shell to regulate buoyancy.
I thought he meant the Helix Fossil.
Ammonites and Trilobites would be the favourite fossils, but once all the Orthoceras were signed by Hank, their popularity skyrocketed.
Siphuncle sounds like some sort of horrible Simon and Garfunkel related lab experiment.
My very thought, and also, hilarious! Here's an example I found on the interwebs:
www.czygan.eu/morph/Simon+Garfunkel_mix.gif
I was watching this, and then it got to the part with the siphuncle at 2:02. There, when I saw the picture, I realized it looked exactly like a little fossil I've had since I was about two and never figured out what it was. Now I know.
the video buffered and paused at that exact moment and in that exact moment i saw this comment incredible!
Anakin Pagaling mines Too!
1:40
- So, how many inch is 15 cm?
- It's almost six, close enough.
- No, no, 5.9 is much better, the next digit is a zero anyway.
- Oh hell with it, let's go with 5 decimals!
Dávid Kertész I'm a metrologist, so I find this funny.
0:41 I knew it! Unicorns are just horses with brain-sucking parasites on them!
fuck you
R/cursedcomments
It's very common to find stone floors with orthoceras in it in Sweden! One of the most interesting things I learned in third grade. :)
Awesome promotion! Other subbable members need to take note of this. There was no begging, it barely even felt like an advertisement!
Scishow tells us to point out errors so note that I'm not trying to nitpick, but at 1:40 you state "5.90551 in" to convert 15 cm.

LFTRnow I can confirm, I'm a metrologist. You are correct.

I live in Sweden and there are those things EVERYWERE! In like stairs
I was about to skip an add on a song I was going to listen to on youtube before realizing it was Hank talking about Scishow! It was refreshing seeing an ad that actually is about something I like!
I thought Sifunkel was the ship name for Simon & Garfunkel.
Lol
I dug up lots of fossils when I was a kid living in Curtisville Pennsylvania about 100 yards north of Kaufman road & Saxonburg blvd behind a garage that they bulldozed into the hill to put in. That hill is loaded with fossils.
our lord helix would be displeased with your conclusion
HE HAS SPOKEN
I just recently showed my class the one I have had for years! Might have to get a second one in thanks for you giving me more information to share about these guys. What a helpful (and for me- timely!) vid. Much appreciated.
Hey !Can you please do a video on Schrödinger's cat?
Love all your videos :)
Petoskey stones are my favorite! I grew up in Petoskey, and I'm always amazed that other people don't even know that they exist.
I like the way you do this show... but I'd rather have one you didn't sign.
Just found your channel... LOVE IT! Finally, something educational instead of mind numbing. NEW SUBSCRIBER!!!!
...who here has played Fossil Fighters and/or Fossil Fighters Champions
me
Me, on my old Nintendo DS.
Good times :')
I have, I havnt played the newest one though
Dylansgames I didn't know it even existed.
Dylansgames fossil fighters frontier screwed up the mechanics and some of the designs, but it has a good story and good graphics, and beating the final boss is like playing Russian roulette but the barrel is capable of holding a ton of bullets and you're pointing the gun at something evil and your life and the rest of the world depends on the one bullet being in the correct spot at the correct time
awesome. thanks Hank. I have many of these in my collection. cheers from the Niagara escarpment!
Wrong.
Helix fossil.
'Nuff said.
IDK hi there
omg, i just realized that thats the one we have in an stone by our stove...awesome:)
live in sweden btw
I'd much rather have a Trilobite... JS
I would love a Placoderm myself. Now those things are awesome!
They are quite common on the beaches here in Denmark and I have atleast 50 in my collection that I've found over the years. I love collecting them so I always hunt them down and take the best ones home.
I don't know how to do much with the new youtube interface
I just got an orthoceras fossil as a birthday gift. It is beautiful!
I'd kiss Hank!
I always like this videos before I watch it and never regretted
Aww, that's adorable!
We asked one of our teacher what they were so she looked it up and we had an entire lesson about them. It was awesome :3
The script writer and the presenter are geniuses
I would love to see an episode about "Singing Tesla Coils." I think they are super cool and I would love to learn how they work!
Hey SciShow-guys, this video got me thinking. It would be really cool if you did a series of videos on the different periods og earth, from beginning to present. Of course, this would mean a whole lot of work, but it would also be really, really cool.

One of my favorite bands from the 60's was Garmon and Siphuncle…
I have got the same kind of fossil at home. Never knew what it was, now i do! Thanks SciShow
1:40 Got to love Sci Shows VERY precise measurement! :D
When Hank said that they are really common in Sweden we was not kidding. In my old school here in Sweden we have these big stone stairs in which you can see lots of them. :)
Hey I am an avid fitness buff (no pun intended), and you should do a sci show on how muscles are built, and where the muscle burn comes from when you work out.
I bought the first one available! so excited for it to arrive
The stone used to make the stairs here at work have so many of these that pretty much every step has at least one.
I would love to see more geology related scishows! I was excited to see this one because I thought you might touch on how coal was made... But ended up not doing so.
At my school we had these fossils in our floor tiling in the hallways. But as you said, they are pretty common in Sweden.
um, you can pause and rewind as many times as you like. I like Hank's pace.
Same here, my school had marble floors and those things were everywhere. But we always thought they were dinosaur tails x)
WOW! I love fossils! You should totally do one on trilobites!!!
I’m looking for a video on how they take a rough fossil with orthoceras and polish it to what we collect and show today.
Hank should do a video on zombie science. I know he addressed the complete lack of zombie science on vlogbrothers, but he did a video on Sharknado so I don't think a zombie video would be completely ridiculous.
I like the sales idea. Really cool
It would be fun to collect fossils and build my own miniature museum!
+SamThe RandomG1rl yea but rly expensive tho
I collect fossils. You have to really look around to find cheaper ones that are still nice. I just got one for $17 that's pretty decent. I do have some that are several hundred dollars though, but they're super nice.

UA-cam teaches me so much more than school ever has.
I've just started using the video speed function, and I recommend listening to the outro at various speeds, and listening to Hank at .5 speed because he sounds totally drunk.
Its like a crazy mix of crash course and asap science
Also the upright posture gives an advantage against the sun. (smaller surface area)
Aswell as granting us the ability of discovering new grounds for food easier, than if we had to rely on trees to get there.
The low amount of likes on these videos compared to the views makes me pretty agitated. I don't want these videos to stop.
I have one I have one!
It's a piece with 4 orthoceras, the siphuncle is visible in each of them :D
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on knowledge that has been repeatedly confirmed through observation and experimentation.
it is - but it's an easy topic to be passionate about.
have a great night and happy halloween!
Being able to name the top ten elements of the periodic table makes you scientist? Adorbs.
I'm sleep deprived and these videos help me go to sleep :) thanks
I live in Sweden and these are really common here. I've seen loads. I went to live in a cottage in Öland (big island) a summer when i was little. outside the cottage the ground was made out of stone, and these fossils were everywhere.
They are very pretty. My favorite fossils are usually of plants or sea rays or large spiral shells.
Love this channel
I love getting smarter here with SciShow.
While I love orthoceras, I have a HUGE thing for ammonites. I've ammonite jewelry, pyritized ammonites, lumpy ones, halves, even one with a layer of ammolite. One of these days I will get a fossilized nautilus, darn it!
Good damn it! Only 20 fossils hank? Come on. You knew there would have been more demand. Are you going to get more. I really want one!
i enjoyed version 3 the most but still loved playing red version when i was a kid
I agree that we should all get along, but the doesn't mean that we should ignore the fact that we didn't get along in the past! We have to take historical facts and learn from them if we wish to flourish and grow as a society!
Love this channel! Can you do an episode or segment explaining binaural beats/out of body experiences? Thanks!
Well, as I already stated more than enough, I can only say either what "we" know somewhat for sure, or what I would assume.
In this case it's a mix:

that just makes Sweden more awesome... Really need to go there someday
Hank,
Do you know Brady from SixtySymbols/Periodic Videos/Numberphile or Destin from SmarterEveryDay and have you talked or tought about a collaboration with them? I know you all have different styles, but I'm not the only one that likes to see you guys working together and how good the content would be.
this video is like an informative sales pitch to get us to buy some stones...
I've had one of these fossils for five years, but never knew what it was!
I come from Sweden and I remeber that in one of my schools there were stone floors and there was allot of fossils on the stones.
Archaeopteryx, Aurornis, Australopithecus afarensis, Tiktaalik, Pakicetus, Maiacetus, Dorudon, Megazostrodon, Morganucodon, Haikouichthys, Juramaia, and Djarthia, just to name some good examples.
Squid cream cone! Great idea for a new Japanese novelty food😋
can we actually get a signed one from you? Would love to support SciShow. I think what your doing and what your changing is great.
Can you please make a scishow about the age of the earth, solar system, and universe and how we know please? :)
These shelled creatures raise the interesting question: Has there ever been a mass die-off due to ocean acidity becoming globally unsuitable for shell formation? A great volcanic event might be enough to wipe out animals that relied on shallow waters and a more or less neutral water chemistry.
So what's the difference between orthoceras and endoceras? I've found one, but I'm not sure about which.
Siphuncle sounds like a dance move.
"Let's all do the siphuncle!"
"Yeah!"
Unfortunately, it is not a dance move.
Yes! A video about fossils!
forget college. This, Vsauce, and Headsqueeze teach me all i need to know
You see them all the time in Sweden, most marble floors have a couple of them. I don't know if it's the same in the rest of the world. But since marble here are often brown or dark grey, white fossils are easy to spot.
I was gonna say something similar! :)
I remember the flooring in at least part of a museum up here; full of fossils!
Thank you Lyria!
The Ordovician wasn't really a hangover from the Cambrian. Palaeontologists identify a significant event in it called the Great Ordovician Biodiversification Event (GOBE), where life diversified in the next 50 million years or so after the Cambrian, replacing many of the weird forms seen in that period
I would like to end this conversation with a quote. "absence of evidence, is not evidence of absence."
The coolest kin was Cameroceras it was huge! if you've seen chased by sea monsters you'll know what it looks like
I have never been so happy to see my name attached to something.
And, based on the study of the, as you call it, 'survival lottery' of mtDNA, the 'Eve' from which all humans originated existed a mere 6000 years ago. That's a pretty solid blow to evolution's timeline, don't you think?
scishow and vsauce my favorite youtube channels
Mmmmm.... Squidcream cones. **drooling**
