Magical metals, how shape memory alloys work - Ainissa Ramirez

I love to understand this concept by watching this ❤️

So, how information is stored in metal? Why a piece of metal won't change its behavior? Why it won't forget? Where is the information? Like, physically and objectively, not with animations? This is not convincing, scientific, or even logical. Reality isn't animation.

Just realized these are bologna slices...

Please look up to "the Venus project" it offers solution to most of the problems we face today.War, poverty, hunger, starvation, illnesses, crime, deprivation, human suffering can be solved with THE VENUS PROJECT. It offers method to achieve better world

Whose here in remote learning?

you should say that there are two types of shape memory allow the one that only remembers one state and one that remembers bot high temperature and low the first only remembers its high heat lets say when you cool it you can shape it and when you heat it it will go to original shape and the second remembers both low and high-temperature shape meaning when you heat it it will become a circle and when u cool it it will become a triangle

would like a video about the reproduction of plants.

Now I knew Victoria secrete :D

I love that the red blood cells are bagels

How its made? 50 50 nickel and titanium?

I learned a lot

Commenting here as there was no place on the TED site to do so.

Listening to this was like listening to a children's audio book. I learned nothing from it that I couldn't have done from a dictionary. I want too know how such materials are made not that they have special atoms capable of realigning. That was something I would have had to understand to consider the subject interesting.

This video was so helpful! I really understand why it works now.

Really, I feel like I learned a lot from this itty bitty video :)

i can't wait to see the kind of materials we'll have in 2050

LOL. You hate others for having opinions contrary to yours? That's....well...that's juvenile, Japhet. Are you a young one?

And being an idiot must be what you do best! :)

And then a bit more time still, with a pointless post! Wasting your time must be what you do best!

I don't know but I just wasted my time reading your puerile chatter.

cartoons and animations doesnt always mean adult free content ! hence proved ;)

Hey thats great

Finally! I know victoria's secret!

after watching this video, m eager to search the web for more info abt memory alloy. And I guess, this is the primary objective of the video - to create interest in this subject. What else can u expect from an under 5 min lesson? :)

I think these videos are very good for getting you interested in a complicated subject like this, and then when you wanna know more, you get more information elsewhere. We are on the internet after all.

But it gives you a general idea, didn't ask for the details only a simple explanation

Good for the Laymen..... Just found out there is A Layperson for the PC-Laypeople : {

theese facts are amazingly interesting,.......so why is science/physics/chemistry class so damn boring.

give me a simple explanation for the general relativity theory of albert einstein then. simple explanations, leaves you without alot of important information.

Why are the atoms sandwich meat?!

This is brilliant.

"If you can't explain it simply, you don't understand it well enough." Albert Einstein I'm sure there is somewhat of a simple explanation and I'll be waiting for it :)

This is cool and all but I feel like it would have been illustrated better with less of the animation. It seemed to me like there was so much it was gimmicky and you couldn't see the wire very well on the theater-type screen.

Ah le troll. Sigh. But, considering u engaged in the discussion, went to wikipedia & watched another vid on the topic, I'd say this intro served the precise purpose for which it was created. And when a young (non-troll) person thinks about memory alloys in the future, what's more engaging, and what might they recall? A white wash indiscernible wikipedia article, of which there are billions, or a handcrafted stop motion animation, of which there is 1? To each their own. Troll be gone.

I agree. I think it is amazing that educators (audio) and animators (visuals) are nominated from all over the world. Similar approach in structure, but makes each lesson unique. Hey Getmethere1, why don't you just nominate an educator that would subdue the irrational rage you have at a video that you opted into?

"Hey, remove your bra, I wanna show you something"

No. Just someone that likes learning about things on the internet. The MIT channel is nice too. Thank you for mentioning it because I didn't know it existed. Now I'm happily subscribed to that channel as well.

You have "just that flavor of inanity" that suggests to me you're an educator yourself.

I never implied that you could not do that. I just mentioned that TEDEd videos do not take that approach.

Thanks. I wouldn't want you wasting your time complaining on more TEDEd videos. They all have pretty much the same approach.

Well, at least it's good to know you're hear to help inform people about what videos they should watch, lol.

"Dumbing down" things so that laymen may understand is usually a way to get them more interested It sounds like you are looking for an entire lesson in one video. There are probably places for that, but TEDed does not advertise itself that way. This video has inspired me to look up more information on the topics covered in materials science, if you do not feel the same then TEDed may not be for you.

I think children are too easily underestimated. This video nicely encapsulates the reasons I always loathed school (even though I somehow navigated through an ivy league degree and and doctoral degree from a world class research university). This is the sort of crap which has dumbed down public education to its current sorry state, IMO.

I truly think this video is quite as close as one can get in a few minutes, starting from atoms.

Simplified =/= dumbed down and content empty.

I see your point now. True, I think I also could make this video a bit better, but the way how SM works is very close to the cinema-airplane analogy. The problem with these phenomena, that if you want to get into them just a tiny-tiny bit further, you have to understand mechanical stress, for example. And it is still just describing what happens, not how it happens. Actually I'm extremely happy with this video, because from now on I can use this analogy when I talk about SM to a young audience.

I think the purpose of this channel is to introduce people to different subjects rather than provide a detailed education about them. Perhaps a different name for the channel would better emphasize this, but I think most people watching understand that the videos here are very simplified.
