Congratulations +Joshua Guillemette +Wallacy Ryan Martins Gomes, +Jonathan Beckinham and +Ella Malabanan, the winners of last Thursday’s “guess the next TED-Ed lesson game” (which you can find in the comments here: ow.ly/11sN3002w3x). Nicely done!
Thank you so much for your great videos, I just like to say in blood separation the tubes are angled (almost perpendicular) to the axis of rotation so it needs less momentum to separate blood ingredients. Thank you
+BenTheMagnifice Not only that, but they said blood cells were dissolved in the blood. Blood cells aren't dissolved. They remain whole in the blood. They're suspended in the mixture.
Adrian BenTheMagnifice Harder to animate a test tube spinning around an external axis as opposed to an internal one? That or just a bad script writer/animator/fact checker?
"Is there a *most* elementary particle? And if so, what's *it* made of?" I've got an even better question for you! Does 2+2=4? And if so, why does it equal 5?
+TED-Ed could you make a video which focuses on the topic of how classical misoc and dubstep music affect our brains and which one is better for studying etc? It'd be really helpful, thanks.
3:53 Wrong! The large hadron collider's use is actually just to put large amounts of energy into particles, which hit eachother and slow tremendously. The energy lost in kinetic motion actually manifests into other particles.
I started watching this during a break in my studying for finals. Funny enough, it ended up being somewhat relevant to my exam in medical laboratory sciences. I can't escape the blood!
they do a great job to explain the concept of what's difficult in the details. so in that sense to understand all processes behind their video is challenging.
***** There's no need to say that at all! You could imagine salt water solutions to be a mixture of two kinds of balls. The smaller ones make it past the SPMs. It's a very natural thing for us humans to do. A similar thing is seen in popular animations of balloons filed with air. They show the gas molecules inside trying to "push" the ballon outwards but show no gas molecules on the outside doing the opposite
A centrifuge spins the tube around an external axis with a tilted angle so the bottom of the tube points outwards, not the tube itself around an internal axis (2:30) ... that is why the red blood cells pack at the bottom of the tube, and not around the sides like the animation shows initially, until it magically fades into the real world situation.
Chromatography is not exclusively gas-phase. There is also liquid chromatography, it's more expensive but enables separation of molecules that are difficult to volatilize.
Why do you show the test tube rotating on it's own axis? This is not how a centrifuge is used. Don't confuse kids please, this is supposed to be an educational video!
"the parts of mixtures we want to separate may have the same physical properties" yea, kinda like giving m&m's to a completely blind person and saying "okay, sort them"
Isn't desalinization of ocean water to potable water too expensive considering there are also other particles other than salt? And since it's needed in poorer countries, doesn't that just make it more difficult to practice
+TED-Ed Guys, I'd really like to see the centrifuge, that spins the test tube the way you depicted it in the video to separate Erythrocytes, Leukocytes and Platelets from Plasma.
+Frank Schneider Does it spin that way? The radius-arm is quite short, so that way of spinning doesn't seem as effective to me as "regular" spinning/whirling.
+Frank Schneider ;) that was too subtle for me. There are a number of other boo-boos in the video too - like the chromatograph-animation at 3:21 - seems like the constituents are already separated before they enter the column...
Good presentation your chemical analysis part was spot on however the animation for blood separation was unclear. the tube is spun to where the bottom of the tube is at the outermost part of the centrifuge. Your animation made it seem as though the tube was spun on its own axis and the cells were pushed to the side of the tube, this is not the case.
But chromatography is not a "chemical" separation technic, because still relies on a physical difference between the substances, the polarity. A real chemical separation is one where you make react one of the components of the mixture, change their physical properties and then separate them by one of the processes that you mention
1:16 that turbine XD 2:27 thats not how they are turned! the small "bottle" is turned with its bottom part further away from the rotationcenter than the top. that way you also get the seperation shown at 2:42
That's not how centrifuges work. And the way reverse osmosis is explained makes it sound like regular osmosis. Pressure has to be added on the salinated side. Otherwise, the pure water would diffuse along its gradient into the salt water until they reached equilibrium.
Just a constructive criticism. The target audience of this video is not well realized. The people who are not familiar with the basic separation processes are not the same group of people who have the knowledge to learn about particle acceleration and collusion.
+Ankush Menat Yep ... they 're arranged inclined, radially in a circle around the centryfuge's spin axis and the blood cells move to the bottom of the tube.
actually gas chromatographie is used only when everything has la low vaporising point. so crime scene use high presure chromatographie. but fairly good overall.

Wwwoohhooo I'm lucky today!! Thank you so much Ted for all of those incredible information and facts that you're offering to us!!!
How can I separate/isolate/purify protein from castor beans' seeds?
The same way they do it with THC in Cannabis?
The only thing that can separate me from my phone is my parents
Salting In and Salting Out are also important separation techniques. They're used as methods to separate proteins for further study.

Minor mistake with the animation for the blood separation. A centrifuge would spin the test tube around a different axis than is shown in the video.
+BenTheMagnifice Not only that, but they said blood cells were dissolved in the blood. Blood cells aren't dissolved. They remain whole in the blood. They're suspended in the mixture.
*+BenTheMagnifice* Yeah, surely they know this, so I wonder why they made this choice.
Adrian BenTheMagnifice Harder to animate a test tube spinning around an external axis as opposed to an internal one? That or just a bad script writer/animator/fact checker?
Jack Linde
Right, they have to find a way animate it! Having only done 3D animation myself, I didn't even consider the difficulty of that.
Adrian That reminds me, I need to listen to the video again, to see if they used centripetal versus centrifugal force. Only one of those are real.
3:30 Who knew it was the muffin man all along...
We are learning about this in Natural Science. Soooo thanks Ted this has really helped me understand it a bit more!

A good video assigned for school feels good man
I started watching this during a break in my studying for finals. Funny enough, it ended up being somewhat relevant to my exam in medical laboratory sciences. I can't escape the blood!
Such eli5 I've not watched in a long long time, simply perfect explanation
the part about separating blood was incorrect. It is centrifugal force not rotational force that is used to separate plasma and red blood cells.
I never understand these vids but i just love to watch them.
they do a great job to explain the concept of what's difficult in the details. so in that sense to understand all processes behind their video is challenging.
They are trying to make it as simple as possible, but something i dont get it becuse the answer can not be easyer =P
The front part reminded me of secondary school chemistry lesson ... but then wow the ending was really thought-provoking.
2:00
It's funny how Salt molecules are shown to be much larger than water which apparently is still looking like a fluid in this scale =P
they don't want to overcomplicate it
imagine if they told people that water has a concentration in water

Did anyone else think the 2 scientists looked like Walter White and Jesse from Breaking bad???
yea
pretty much the summary of the importance of chemistry. I know I picked the right education here.
Chromatography is still based on physical properties of analytes... It is NOT chemical interaction.
Just to nitpick a little, distillation is a separation technique based on difference in volatility, not boiling point ;-)
A centrifuge spins the tube around an external axis with a tilted angle so the bottom of the tube points outwards, not the tube itself around an internal axis (2:30) ... that is why the red blood cells pack at the bottom of the tube, and not around the sides like the animation shows initially, until it magically fades into the real world situation.
Also chromatography is physical separation. If you needed an example of chemical separation you could have used precipitation.
but precipitation is when gas turns to a liquid physically...
Best one yet.
good job guys...with we had these videos in our schooling
"How do we seperate the seemingly inseperable?"
Marriage.
good1
Chromatography is not exclusively gas-phase. There is also liquid chromatography, it's more expensive but enables separation of molecules that are difficult to volatilize.
The moment when a TED-ed video is about something you're going to be doing an exam about in lab.
TED-ED is one of the science channels that make my morning by 'feeding me'.
This video could have been 3x as long and it would have still been too short. Regardless, TED did a great job as always!

"the parts of mixtures we want to separate may have the same physical properties"
yea, kinda like giving m&m's to a completely blind person and saying "okay, sort them"
So the chemical reactions would be like the blind man sorting them by licking and tasting them, right?

This took my sciences class a week to teach us this XD
+KhansVideos2641 at that rate they should replace most of schooling with these videos then.
i think they should let students somehow watch these videos individually to get a clearer understanding of the subject
thank you...
U just explained a whole subject in my uni in 4 min
Reverse osmosis seems like just filtration?
They don't 'vaporise' at different points. they condense into liquids at different sections of the distillation column.
Good presentation your chemical analysis part was spot on however the animation for blood separation was unclear. the tube is spun to where the bottom of the tube is at the outermost part of the centrifuge. Your animation made it seem as though the tube was spun on its own axis and the cells were pushed to the side of the tube, this is not the case.
FYI they use a centrifuge to separate the plasma from the red blood cells.
