Ever wondered how your smartphone works? Take a journey down to the atomic level with scientist Cathy Mulzer, who reveals how almost every component of our high-powered devices exists thanks to chemists -- and not the Silicon Valley entrepreneurs that come to most people's minds. As she puts it: "Chemistry is the hero of electronic communications."

She tried to slide in various puns throughout the talk but the audience didnt give a damn.
Professors and engineers don't have a sense of humor
Her heart died inside
13 min of dieing inside straight
Me trying to figure out why my stupid teacher wants me to watch this:
Not very accurate statement. 1:00 The real elfs of smartphones are the child labor force in Gongo, digging up rare earth metals to be processed into chips and batteries.
so I've watched a school project "how its made" again. Isn't TED supposed to be about the ideas?
Primary school project... with some background in electronic engineering this was painful to listen to.
@Aviri Char oh wow ur so smart
I'd say the importance of chemistry in making possible information technology is an important idea that is often overlooked.
ooooo this give me so many ideas for what i should do for my chemistry IA
I feel you man I had no idea
It's amazing how much our smartphones can do and how they work. I just feel like I'm not using it for its full potential.

All in moderation. Its just a tool. And you become a tool if i have to bump into you on street.
It's okay, Google is making up the difference 😉
Laugh 😂 so badly ! It’s very incredible thought for me. My smartphone deals with CZcams suddenly finding you about an incredible message to me for sharing it. Thanks for sharing it
5:54 that lady in the middle's like "really =_="
XDDD
Can't see it. All I see is a bunch of Gen Xers sitting around thinking, I can't believe I'm sitting here watching some don't know s%^t from clay, preggers millennial, when I could be in a bar or smoking some weed, getting hammered.
Wow exactly ! I noticed that a mother board & earth towns borders etc look like a mother board from an above aerial view from airplane window view. I chose Chemistry in 10th grade. I love chem it is the root of all indeed ! Super interesting subject. Chemistry of love for instance ! It is 1 of the most amazing sciences. I loved the periodic table when 1st saw it in class ! It was easy enough for me to understand this subject. I love mixing juices, food cooked already or a recipe. music mash ups, etc. Chemistry is just a recipe if a mixture of chemicals or substances.
You gave many answers I didnt know I wanted. Thank you, Cathy
when she said "blue, red and green" instead of "red, green and blue" that made my OCD trigger.
I think the former sounds smoother.
Thats just your pickyness triggering. Look up what real OCD is. Try not to throw it around so much
And "on accident" amongst many others.
and i'm here wishing it was "red, blue and green"
Brick Tamland she doesn’t even know what RBG is...
i can make only one positive & accurate conclusion (after watching this video): Cathy Mulzer likes a chemistry much.
is it really a TED talk? looks like some schooling session
It's not only chemistry, but also physics.
I think I'm gonna get r/whooshed but isn't chemistry physics?
@@briankim2555 Well yes, but actually no.
@@micha5816 yeah I got confused with energy and chemistry lol
@@briankim2555 Me too
Physics is the root. Ask Sheldon for his Powerpoint on that.
A short overview of chemistry in our phones - but my God, I need to find myself a woman like her
Amazing Speech!
I LOVE GETTING SMARTER! Thank you TEDTALKS♡♡♡♡
Isn't phone size stuck at how big we want our screens? Surely we can build smaller phones, but the screen would be too small to be enjoyed from anywhere other than right up next to our eyeballs ;-)
But you always want your next Smartphone to have roughly the size of your last one, but with 10x the power. So you have to get way more technically advanced chips/boards. That's basically what she said, more power requieres either more space or more advanced chemical products.
🦋it’s to easy to focus on the basic but we don’t think about what all goes into it
What we see here is the progeny of character Cliff Clavin from the old TV series Cheers.
I”ve finally attended a Chemistry class😀😀😀
Somebody explain to me what the lousy metaphore of glue and mountains is supposed to represent in 5G. Am i understanding the motherboard layering is too corse for signal integrety, and we need cleaner methods to etch connective wires in PCBs? Or that reaching that level of stability would lead to disintegrating boards?
WHAT DOES IT MEAN???
For copper layer to securely bind to substrate it has to have some roughness, otherwise it wont stick together very well and will delaminate under repetitive stress. This roughness is critical to structural integrity of PCBs but causes signal degradation. Here, found a paper about this (kinda): www.circuitinsight.com/pdf/signal_transmission_loss_copper_surface_roughness_ipc.pdf
@@artiomvas you are so amazing
wow! amazing Chemistry power! Thank you....
A great advance would be to replace those rare-earth metals used in smartphones with something more sustainable.
Everyone watching this should ask themselves what they've really learnt now. She's throwing a bunch of metaphors out there without really explaining what most of them mean.
'The 5G signal is driving its car too close to the copper's velcro and thus has to slow down, because there are mountains!' is not really helpful in understanding any of the underlying concepts.
Using familiar words is not enough to convey meaning, even though her energy and use of visuals had me excited at first.
Ye right, it is just the vain pomps and vanity of her being very shallow..It is like a devil uses Jesus' talking skill..
There are same implications used by a lot of ppl as an evidence they are not passionate or faithful to their own superficial words.
Good Cathy
한국어로 번역된 건 없을까요 ㅠ.ㅠ
But is a smaller phone really worth child labor in Africa to source cadmium for the battery? Not to mention all of the energy and carbon needed to move materials in the supply chain back and forth, and ship the phones all over the world. What about end of life? Is it worth the millions of tons of electronic waste sent to third world countries where workers salvage precious metals under hazardous conditions?
What if instead we designed a phone with very simple components to do what they were designed to do- talk to other people? And what if their default state was off, instead of on? What if they were powered by shaking them, cranking them, by using AAA batteries, or leaving them in the sun? What if they came to you in a few pieces that you had to then assemble to offset production costs and provide a modular design capable of using new components?
Great job Cathy! 👍🏆
It's an art to be able to explain technology in such an accessible way and given only very few
Thank you for this interesting, very comprehensible and clear explanation 😊💖
I love systems & technology and to discover how things work. I never knew about this role of chemistry.
Thanks!

Thanks you nature..and thank you me...I created my self
I feel like clark kent without my phone..don't leave home without it..
“Chemistry is the hero of electric communication”
Changed my mind
good thing processor architecture and computing isn't complicated and also built on a foundation of countless innovations
It's not only chemistry, but mainly physics.
@@micha5816 it's kind of unfair to attribute anything to literally the laws of the universe
The real question is, Did she convince them in the end?
Very different from just public speaking, When a person is first learning to give presentations power point type especially you die a thousand deaths often. Even when you start to loosen up , like her, become more natural as well as know your material it is still hard AF . What I’m saying is those jokes deserved laughs damn it! Help a sister out .
well.. they weren't funny XD she did a good speech but sure being funny is not women first prerogative ^^
Dennis C. Her humor came across as too rigid and unnatural since it was presented the same way as the rest of her speech. Totally agree with you on it being difficult AF though.
A software developer is feeling surprised... WOW!
Un exposé très "société de consommation et de plaisir" !
we are in service economy with data scientists working in "industries" such as banking, mortgage, finance etc. Only a misguided goes in to learning chemistry in this economy. It is up to economies like Germany, China to do such things
Did anyone hear the people in the crowd saying "Who cares?"...
Time?
Lmao I reread and I finally understood
More than chemistry, electrical engineering, and material science are at the center of smartphones and she never once mentions this.
@Aviri Char Yes, what you said is true but claiming chemistry as the overarching force behind the smartphone is misleading and disingenuous. It leads to a reductive understanding of a piece of amazing technology. It is akin to saying that Biology is the reason for minimally invasive coronary artery bypass surgery as opposed to medical science, electronics, and robotics.
This is a non-trivial difference because younger people watching might falsely conclude majoring in chemistry can make you work for semiconductor manufacturers or electronics companies but that's not true.
If nothing fits in ladies pants pockets then why wear paints!?!? Sorry couldn't resist. I do like printed circuts. I am a wiring guy for cars I know my pickup wiring pretty well I have had to rewire a few trucks and I will say circuits are truly unsung heroes of the world. chemist do lay the ground work too.
I love that people understand chemistry, I personally hate chemistry.
Wtf? Xd
@@shakeybritches8089 Chemistry is above my head. Would like to understand it, but science isn't a strength for me.
@@shakeybritches8089 good thing is you can learn how to learn! its definitely its own skill by itself, it comes easier to some people sure but people that get degrees in science have to spend countless hours at that same level of frustration to understand the stuff they need to because at some point for everyone things dont just make sense automatically
@@shakeybritches8089 fair enough! no need to force yourself to do what youre worst at, I just hate to see people tell themselves that they just dont have what it takes to learn a subject they want to learn about. Im almost done with my engineering degree and a lot of people just work HARD at it for hours and hours a day, where it may take someone else only an hour. But that same guy might spend hours and hours trying to understand a different class, because if whatever youre doing always comes easy you arent doing enough!
benifict for me
I'd think the unsung heroes of the industry would be the underpaid workers in the Chinese factories cranking out all those devices for us.
And the idea presented in this talk is...?
#AskMKBHD @MKBHD
use only chemistry to make nano copper wire. don't use math, physics, etc. Can you? no ... technology does not advance only from chemistry. Technology is created from various sciences. All science is a hero in technological progress.
The real elves are the little boys and girls in sweatshops.
China has surprisingly high school attendance for the relative rural development, that's why East Asia is increasingly important in tech manufacturing (besides robots).
Smash!
👍
Dr. Stone brought me here.
She’s so damn cute.
Jimmy Bentley wtf
???
unbelievable, such talk absolutely UN-worth spreading.... think of those whom work in the mines 12 hours per day and 7 days per week, digging and extracting the very basic materials ...... we have nothing without people dedicate their live doing those jobs..
there is NO hero for all that..... very innovation just a combination of the knowledge of all mankinds through thousands of years...
very disapointed by such level of TED talk
Dr stone explain the copper wire part too, 😍.... You ppl should try watching that Anime it's informative
I'm pretty sure atleast 90% of the people in there know what a motherboard is. -_-
The explanation was ok but the lady won my heart bcz i feel that she is soo cute & pretty that I'm expecting my future wife to be like her. Let's have some noise for desi single boy. #cathy cutiee pie identical to my future wife.
Reminds me walter white "Breaking Bad"
What kind of phone are you watching this on?
Refurbished Prototype
Samsung Galaxy Note 2 been loving this device since it was new.
@@susan137
Wow! Seven years is a good push. I'm on the S7 with a flailing, but extremely overworked, battery. I also bought mine when it was released.
I bought a Note 10+ 5G three days ago and can't wait to transfer all of my data.
I do love me some Samsung.
Refurbished Prototype
I looked at the Note 10 just days ago. The cost makes it unreasonable for me ... and I'm not sure I'd love it better.
I'm working on being a minimalist.
@@susan137
The only reason I got the 10+ 5G ($1,300 msrp) is because a guy bought one for his wife at the same time that she bought an S10+. The Note was too big. He sold it to me for $700 in a sealed box that cleared all background checks.
💥🔥🔥🔥🔥
Refurbished Prototype
That, I'm sure, was a fortune occurrence for you.
I'm sure I've bought a new battery for my Note2 and it needs another.
Nothing against the speaker but the majority of the talk felt somewhat unnatural. Every sentence was packed with some sort of key word, e.g. "You see", "Don't you agree", "Now X is special" + a joke every few sentences to keep the audience interested. It was too perfect in a sense, not what I'm used to from a TED talk.
Besides, do we really need 5G to fuel our excessive consumer needs? To share even more data with companies and governments while we still don't even have proper privacy protection in place? Downloading entire movies in seconds on our way to a plane is a luxury that we shouldn't take for granted, especially with our climate crisis in mind.
I guess I just miss the old Nokia days where the phones already had long lasting batteries and could withstand being dropped without a cracked display. With every new invention comes a certain responsibility. If we continue blindly throwing new tech at consumers we end up with more and more problems in the future. Today's smart phones have already turned us into greedy, anti social data goldmines.
I agree with you, we don't need more adictions. People are losing their humanity with all this unnecesary technology. I'm glad to have grown playing soccer with my friends without all these devices.
You are right! I also miss Nokia days, nowadays anyone can find you even if you don’t want it!
Lara, ok. Do you have any opinions about the actual contents of the talk?
@@BoWeava Well, the speaker's goal was to get us to agree with her. I agree that the underlying chemistry and science achievements are incredible. I'm just not sure what to take away from the talk, other than to get us excited for even smaller and more efficient tech (for which I have certain concerns).
I dont think she put her own opinion into this presentation beyond relating to everyday things we run into or might question. I think she was great and i can only sit through 1/3 of the ted talks. Not all are going to hit you as you'd like. Very informative nonetheless.
Cool but why do you have to pair up referring to the smartphone with some kind of praise like "the reds blues and greens we enjoy," "the displays we love so much." Its actually every single time
Interesting how humanity so easily forgets or ignores where everything originates from, imagination. No so called smart phone or A.I. will ever surpass such eternal supremacy.
Neville Goddard knows.
Hmm thought you were going to say China
I have a potato powering my smartphone, because it runs out of battery at 15% for some reason
How to make a boring presentation about an interesting thing

Yeah chremistry takes it so far, but without physics well thee wouldn't be chemistry.
All sciences are connected. Chemistry is just applied atomic physics, and biology is just applied chemistry. 😄

Without math there would be no physics
@@MrHarsh3600 without stuff there wouldn't be stuff
She says 'we want' smaller and faster phones, later on, 'we're being told we want' something called 5G. I think the latter is the closest to the truth. On the talk itself, it seemed pretty useless - wasn't really an idea worth spreading, it wasn't an idea at all.
To bad man did not lead this development. Men should lead development of this technology, not women.

As a layman I found this utterly boring.
Little awkward wording at some parts (e.g. “the blues, greens, and reds we enjoy”) but overall informative. Just wish that the humor lines were either said more naturally or just left out altogether since it just seemed forced/rehearsed.
I only clicked this cause she's pregnant and has great facial structure
due to chemistry
lmao
She's cute
Damn :))
Poor physics. Nobody is here to Jack up
you truly do not have a clue
So a phone is addictive but reading a fucking book isn't????? Lost me there. How about just sticking to the point you were trying to make. "Smartphones, the root of all evil"

You've got the wrong end of the stick mate.
Doesn't matter what Scientology says. Scientology is woo pedalling.
What I meant was TheJociman meant to say science course, not Scientology. I was also having a dig at the TED speaker for her loose grasp of the English language.
I think the three of you need to calm down, a scietologist always keeps a ”cool” head. I agree with the speaker on this one. I doubt mr Jimmeh Bees rationalization skills as well ShakeyBirtches.

So I watch this whole thing with just a few minutes left, so I thought, 'This has been a rather benign talk about chemistry and its roles in technology; I suppose I can give a thumbs up.' So I click the thumbs up button, just in time to hear her bring up 5G. And by the time she said she's glad she can download movies to her phone in 40 seconds while on her way to the airport, my thumbs up had turned into a thumbs down. I hope it's that simple. I really do. I hope 5G is nothing but the best and fastest internet ever. But it will never be just that, even if it is that at all... Convenience over privacy and health.... that seems to be the way things are going...
If you want Privacy, then don't get a phone in the first place
The moment you get a phone, the government can get whatever they want from you.
Also the convenience will be there, as long as your device supports the 5G capabilities to their fullest extent
complete waste of time. none of graphics is teaching something.
She's funny...but not
She looks *pregnant* 🖖🤗
a very boring and uninformative talk!!!
