It's like agar.io

They were teaming!
omg I was just about to say that cx

I can't recall how many times I've been told that there is some magical barrier between life and non-life. If anything, the difference between the two is more of a sliding scale of complexity rather than a dividing line. This is probably one of the best examples I've seen of something so simple and inanimate performing tasks we usually ascribe to living things. Great Job Derek!
+Brandon Hall It's more of a wishful analogy than an actual example.
+Brandon Hall The difference between life and non-life is astounding. Else, why hasn't a scientist ever created life in the lab? I'm not talking about taking something already living and making a change to it. I'm talking about taking some kind of raw ingredients and making life from it. We can't actually do that. The closest scientists have ever come is probably the cloning process that produced Dolly the Sheep and even that began with an existing viable egg cell and a nucleus. Those scientists didn't make the egg or the nucleus. Making life from non-life must be very, very difficult or this would be commonplace.
The example in this video, while interesting, is such an incredible leap from non-life to life that no objective scientist would waste their time defending it let alone promoting the argument. It's just too full of holes.
+DuelScreen Apparently you do not know of the Miller-Urey Experiment.
We did make the raw ingredients of life from inorganic compounds. This was done in 1952. Go read some books, would you?
+Brandon Hall The differences between life and non-life (death) is very similar to differences between liquids and solids. You can clearly see they are very different but the more closely you examine the border, the harder it is to see any. Close enough, you can no longer tell any difference: solids kind-of flow and liquids kind-of don't. (This was partly covered in Derek's video on glass, pitch and Earth mantle.)
+Brandon Hall Apophenia. Similar does not equal identical. Water evaporation may be an analogy, as Deego said, but not an example. We can't be naive enough to assume just because something acts similarly or looks similar, that it serves the same purpose. Lighting has similar patterns to veins. Neurons look eerily similar to a projected view of the structure of the universe. Likewise, the physics of evaporation looks like microbial life. Certainly nature has patterns all throughout it, but not all patterns are correlative.
so deep...
so simple...
so beautiful....
so... natur-al
+jhony arias agree, it was close... than started some bullshitting.. but it was really close! :D
Maybe its maybelline
+jhony arias not natur-ol?
man, you are high, these are only drops of water.
What if you used sperm?
Great work Derek. A genuine, original and creative video. Kudos.
Very cool, I'm sure you could use the moving liquids for cool movie special effects
Oh hi
With names between them？
What's the show be called, maybe just Droplets?
Ah, so basically what you're saying is that the reason I can't get that girl I've been pursuing is because we both contain different concentrations of water, and we evaporate at different rates. It makes so much sense now! ;-)
The clear answer is to take water out of the equation entirely. Dehydrate yourselves,and your ashes will live together forever.
Or,maybe,you could just water her like a plant to try to compensate for the difference in moisture. Just splash her with a gallon of water per day. xD
@@nolanhaggen8252 There was that drunk girl in a bar one day, trying to make contact, the high concentration of her perfume and alcohol kept pushing me away, even not seeing her instinctively made me flee as I was not wearing any perfume nor very drunk. Experience conclusion validated.
Exactly that but with alcohol.
So all the guys run from me cause I’m too concentrated for them. Makes sense.
Actually, it's the water that's playing hard to get. 😄
It is so cool, nice video :)
+Louis DUPRE BERTONI Glad to know that some other personnes francophones watch veritasium
+Dr Nozman lol mon ami ur here
This slow zoom during you conclusion enhance it so much. Strange how such a simple thing as a zoom can make such a difference between some simple sentences and a powerful conclusion about life.
One of my favorite Veritasium videos so far, loved it.
I've been a subscriber over a long period of time over here...and probably it's the most useful channel on TH-cam.👍
The music that starts at 0:32 perfectly captures my mental state.
Got the mechanical monkey in my head dancing frantically
one of the best channels on any medium. thank you v for your time and teaching.
The secret to cooling glass without it shattering is to cool it slowly. Glassmakers will actually cool their creations in an _oven_ that slowly heats the glass less and less over hours or days.
So something like a two-step process of cooling the glass in a kitchen stove first might actually work. And not putting it on cold metal to cool because that draws heat out of the glass like there's no tomorrow.
+Penny Lane Yeah I was going to mention this as well.
This is absolutely amazing!
That last point before the 'credits' especially.
Thankyou Derek.
im just imagining giving this as a science presentation. that would be so good
OH MY GOD YOU'RE A COLDPLAYER, I'VE SEEN A LOT OF YOUR COMMENTS ON COLDPLAY VIDEOS BUT SEEING YOU HERE MADE ME ESPECIALLY HAPPY.....ah my heart I love both veritasium and coldplay
Thanks V. Long time no see, hope you make more videos. You are actually my favourite subscription. Very thought provoking.
you just explained life and evolution to me, somehow I never could understand how the essence of all of it worked,
+Dalloz Cansing I see what you did there, but still far away from explaining the origins of life ;)
+Dalloz Cansing
movent of gradient is a very important part of cell life.
But i would rather say it is something the cells(extremely often) use,
but not "what they are".
to be honest using the concept of evolution on things like this does
hardly make any sense to me, as how does a droplet survive? how does it
reproduce? it doesn't even have genes?
I think its a faszinating phenomenon but this is the first time in your
videos i found the conclusion too simplified. :)
keep it up :)!
+Milky Cowish It's a big part of the basic ground work of the beginning of life. Just like phospho lipid bi-layers, and amino acids synthesized from inorganic compounds by natural catalysis.
+999is666upsidedown
Jesus used smaller words and made much more sense, just saying...
Jesus made 0 sense though, so yeah.
It is my second most favorite video on this channel and on youtube. Splendid.Thanks a lot.
1:27 the quintessential Veritasium music! always love it when that music starts playing. I feel like thats when the video really begins anyone else?
+Kaiser William so happy when i hear that tune!
+Kaiser William same as in vsauce videos.
Very interesting, and I appreciated the subtle camera zoom when you were explaining the microbes' natural usage of basic chemistry.
Those drops on the slide, still better than all the new cartoons. #bringtomandjerryback
Your definition of life is so incredible.
3:00 that's a very strange kitchen.
Y?
+John Smith Or maybe, just maybe, he cleaned his kitchen because he was going to film there...
+FunkyFish Its probably a set.
+FunkyFish no one cares
+John Smith What is strange about it? Looks like a kitchen.
Fascinating. Thanks for introducing this, Veritasium. Lots of stuff I want to look into now.
I love how I get less existential crises and more of a sense of wonderment with these science-y videos :) thank you
You know it is a good day when Veritasium releases a video! :-)
Can you be my science teacher? I understand this so much more than what i learn in lessons for some reason.
Hello from Russia. I don't know English, but I love watching translations of your videos. You explain things in a very interesting way, and thank you for that. Sorry for the clumsy translation)))
Actual life is a bit more complicated, but really great demonstration. :)
+Pieceratops Don't pretend that life is more complicated? lol, ok. Tell that to all the microbiologists who study this stuff for years.
***** Eugene Khutoryansky? Is that you? I had no idea you also made "cartoons and stuff".
You should do an entire video with just those water drops chasing each other around. 4 or 5 minutes of lighthearted music and fun colors can brighten anyone's day.
Has this channel and VSauce and or ASAPScience ever collaborated?? They would all go so well together!!
+MrsMythical YES, with Vsouce.. Search for "what is NOT random" video.
Veritasium and Vsauce actually did 2 collab videos, titled "What Is Random?" and What Isn't Random?"
+MrsMythical Check "Some Surprising things" video on Vsauce's channel ;)
thanks everyone for replying, I will look it up!!
+MrsMythical He also did a colab with Destin from Smarter Everyday about the Toilet Swirl and australia stuff
Neat, a new Veritasium video! I was just watching Uranium: Twisting the Dragon's Tail, so happy I was able to catch it on TV this time.
Great agar.io gameplay right here man!
It is fascinating indeed.
Keep up the good work Mr.Derek.
Some straight up wizardy here...
My dad, the wise man that he is, used the soap and pepper illustration to tell a story about Italian immigration when I was a kid. He put the pepper in a bowl of water and said that the Italians came to America to start a new life, but when the Americans told them they had to bathe [he sticks the bar of soap in the water] all the Italians ran away. Yes, the great knowledge of my father...
"When I put Sam Pepper into this pot of boiling water."
Lol, didn't expect that coming 😂😂😂
Wow, this is one of the greatest science vids ive ever watched on YT, because it blew my mind with a magic like phenomenon first and then explained it using some of the most basic rules of molecular physics, which I personley have been tought in 10th grade (german gymnasium)
Wow... going from foodcolouring on a glass slide to the formation of living organisms....
This is so cool . All the times I've worked in kitchens with food coloring I didn't even notice they did this.
*I thought the title said at first," Do These Liquids Look Alike?",then I actually noticed it didn't, lol! :D*
Lol same here
me too
+Abalam Anderson Me too! Why did so many people read it that way? XD
Great vid Derek. Simple but so utterly enjoyable. More of these kind of vids please (slinky/beaker balance/ice spikes/rotating pvc pipe, chain drop, etc).
Is it me or does this look like Agar.io?
+Mayur (「 Mayur 」)
well that game is based on molecules so yeah
+Mayur (「 Mayur 」) same
+Mayur (「 Mayur 」) The first thing I thought of was agar.io xD
+Mayur (「 Mayur 」) Agar.io Hyper-Realistic HD Version 2.0!
One of the most seemingly puzzling questions- namely how life began from lifeless chemical processes- seems to have a really simple answer when demonstrated so beautifully.
When are you making the transporter video?
the slow camera pull in at the end was a nice touch, for a one man show
I break apart when I got stressed too, am I a piece of glass?
Great to see a video again, was looking forward to one. Busy with the snatoms I imagine
First ! Now mom will finaly be proud
finally*
+Tómas Orri Örnólfsson oh wow.. fail.
HJMadventures
I really liked this one. Your final comments regarding how life evolved was pretty inspiring. I usually think of evolution as being restricted to life (even higher forms of life), but it makes sense that it applies to simple chemical processes as well.
Thanks!
Wow, this just opened my eyes. Biologically, this is possibly how life started. Water and motion... just amazing.
Awesome. Thanks to spend some times to talk about this kind of experiments.. I mean a lot of people talking about science on yt "reduces" science to cosmology, quantum physics etc. many things in science are very interesting and challenging for our mind. Actually every think in science is interesting, it is like Feynman said, study any subject seriously in depth and you will find it fascinating.
Oh hey, Snatoms!
Great video! I was totally able to enjoy all 5 minutes of it and then write this comment.
I was wondering.. Would you maybe write the keywords/terms on the screen when you say them? English isn't my first language and I have some dyslexia, so I can't spell it for further research or put it in my flash cards. :)
Most excellent. So beautifully expressive of the spirit of science and of the character of scientific understanding.
It's like the game Agar.io
Also known as cancer
+Roland Hkj yeah minus rage and douche-bags who split to eat you up
@@guyclykos Aren't you supposed to split to eat people up in agar.io? Why are you calling them douche-bags?
Hey, that's the song used on the Tipping Point Math channel! Worth checking out, i'm sure many of Derek's fans will find it appealing.
And again...you should be wearing googles when working in a lab (preparing slides over heat) even if it is your kitchen.
***** Thanks...stupid autocorrect.
+Nexus2Eden He is a pro xD He doesn't need protection
this experiment doesnt require googles unless you have no idea on what you're doing
Riahisama You always wear goggles when conducting experiments, it is lab safety 101. Because you never know what will happen just like the slide shattering...it could have injured him and every scientist knows this.
SuperBulisHD Ahhh...yes he does.
From my perspective as a biologist - the best video so far. You completely clarified a "naturally adapted" misconception that millions of people still possess; that life is somehow different than a combination of chemistry and physics. You clearly explained that life is simply an emergent property of these. I don't think you follow what your PhD indicated anymore, currently your videos are both clear, explanatory and clarify misconceptions. Merging these traits you grant a great contribution to future academics.
They move because of the midichlorians
I love your work, every time, Derk of Vertiblastium.
this is like the game agario
Fascinating! I'd seen the pepper/soap thing in school, except we used lycopodium powder - pepper grinders were only to be found in Italian restaurants back in those prehistoric days! But I have never seen or even heard of the experiment with different concentrations: thanks for showing us and explaining so clearly.
Every time a veritasium video comes out, I feel like I need to drink vsauce, then I might become smartereveryday, it's not like I can understand physics in a minute, or the earth in a minute, but PBS studios fills the void that school doesn't fill! ;) Like if you get that!
+Manas Sarpatwar If you fell like a zombie you shall try a bit of thebrainscoop
one of your best videos, loved every bit of it, thanks!
why can't science in school be like this?
***** True dat
+Chris Allen because teachers passionate like Derek are rare specimens. Also they have to obey ministry of instruction programs, which is sad as often ministers of instructions are ignorant as goats
because if you are learning something like this in a school, then you will also have to learn this in great detail which will include math and equations and what not.
but in this and most other awesome science channel, they skip the math and all the additional details which one must know in order to get a degree in that subject..
so short answer is this,
in these youtube channels, you just get an introduction and the beauty part of it which makes you go wow.
However if you want to come up with such wow things, you need to know the stuff in detail. (including math and equations probably)
+FloatHeadPhysix Very true, but a teacher should nevertheless strive to cultivate that wow feeling and sell the lessons by also sharing his personal wow feelings
+FloatHeadPhysix No reason it couldn't be shown in the younger years of schooling in order to get students interested in science
Every video you make is brilliant!
0:16 - I thought he was going to say
"It looks just like Agar.io"
Your videos are top notch. Love your material mate.
Watched first 20 seconds. Theory : It has to do with concentrations of contents just like salt attracts water. Let's say that a colour has negative concentration. It will attract positive concentration to make it neutral. Or it's electrostatic magnetism kinda.
Once again...awesome video. Science is coolest when simple rules have complicated results.
AGARIO IRL
This is kind of funny to watch, especially with the music. Really good video!
why are there so many evolution deniers in this comment section? it's not even about evolution. was sure most evolution deniers would be attracted to comment on a video that says 'ecolution' somewhere in the title.
+Yelena Antipova Им всё равно. Они просто хотят поныть о наболевшем ))) Креационисты их не понимают. Эволюционисты их не понимают. Видимо им одиноко - вот и ноют чтобы привлечь внимание )))
nice to see your using your snatoms in a separate video
That thing with the drops looks like agar.io
+Joe Higgitt agar.io is supposed to look like cells chasing each other, so that makes sense.
I noticed that in high school ... never understood why ... THANK YOU for explaining this !!!!!
+Captain Erio - What about all us misfits that didn't go to high school? All we had to experiment with was our drugs.
2:28 dab
+BenCubed I see you also like cubing
Yeah I main the yuexiao and average 19. How about you?
This is a fascinating concept! Thanks for making a video on this!
What is the happy bouncy music used at the beginning?
+Curt TDH Its a tune from Kerbal Space Program
+Blindobat
Thanks so much!
Curt TDH no problemo!
Do 10 hours edition pls looks calming
Now I don't feel sad, even at microscopic level there is something called friendzone.
Fascinating and inspiring. Thank you again, Veritasium.
4:05 Anyone else think of Carl Sagan at this point
You rock. Great vid. Been waiting eagerly for this vid. The parlor trick can be taught to kids very easily and with much fun.
It's like Agar.io game 😂
+Dr.Re lol
Really interesting video! I am always happy, when the TH-cam app 'dings' and it shows me, that you've uploaded a nrw video.
Thank you for your work, and keep it up! :)
agar.io real life
+ALTERNATIVE Gamer Exactly what I was going to say.
+ALTERNATIVE Gamer Don't steal my jokes
Ehehe trololollolo
+StormCrusher94 it's not even a joke. It's a fact
This is so fascinating. I love how much I learn from your channel.
Looks like agario took over the world
+Job van Dieten This is Veritasium's secret way of playing it!
Loved the last line, exactly my thoughts!
Reminds me of a real-life agar.io
: D
Very nice effects those droplets do.
0:10 thats a real life agar.io
Loved It dude!
One thing though, the microscope glasses shattered mostly in the middle I presume, like they did in the video?
The cause is in part what you said, but what really satisfied the breaking limit was probably placing them on that grill, and the reason is that when the glass compressed again, as you said, the thermodynamic stress tensor exploded because of very different coefficients between the metal (a thermodynamic conductor), and the air in the room (a thermodynamic isolator). That in turn made the glass compress unevenly.
While glass is an extremely viscous liquid in our sizes, pressures and temperatures, it's not a fluid enough, and so it shatters :)
I only made a fair assumption that you where on earth in making of the film.
peace
real life Agar.io?
very concise definition of life. bravo.
wtf? that is not how surfactants work, they create thin layer on surface creating lower tension because of their hydrophylic and hydrophobic parts, they replace water molecules on surface not strengthening the attraction of water molecules. Another thing is that water is terrible at evaporating because of its molecular shape and hydrogen bonds, if there was only Van-der-waals attraction between them it would be gas far below 0°C. So don't spread missinformation just like with the baloon and water stream video (saying that what was thought in school is wrong when it is not, just not full explaination and you were presenting other part).
+Natalia Ja He did talk about the hydrogen bonds.
+Natalia Ja At what point did he say any of those things? And I don't think any molecule can be "terrible" at evaporating. It isn't a skill that some molecules practice more than others. Some evaporate more readily than others, but he didn't deny that, just said that water does evaporate, and that it evaporates more quickly in a less humid environment.
+Natalia Ja Yes, I was thinking the same thing. Water dose not evaporate faster than 1,2-propandiol because it is lighter but because it has higher vapor pressure due to less hydrogen bonding. Its the intermolecular interactions that are important not the weight! Also like you said the "description" of surfactants in the video was very misleading.
I am quite disappointed with this video, Veritasium usually holds a higher quality...
Frozlix The bonds affect the weight, maybe it was about that?
No, the bonds does not affect the weight. The type of atoms in the molecule affects the weight.
Looks like I checked your channel on exactly the right day :D
