Join Anna Ploszajski to learn about materials science - the interdisciplinary field of researching and discovering materials - in ways you'd never imagine through the world of craft.
As a materials scientist, Anna has turned to storytelling to communicate her work in new and engaging ways. Through her stories and demos, you'll see materials in a whole new way.
This lecture was recorded at the Ri on 9 May 2023.
An honorary Fellow of the Royal Academy of Engineering, Anna Ploszajski is an award-winning materials scientist, presenter, comedian and storyteller based in London. She’s a materials generalist, equally fascinated by metals, plastics, ceramics, glasses and substances from the natural world. Her work centres around engaging traditionally underserved audiences with materials science and engineering through writing, podcasting, presenting and social media. Having developed her own unique blend of autobiographical scientific storytelling in her first book, Handmade: A Scientist’s Search for Meaning Through Making, she now trains professional technical people to communicate what they do better, through the study of story. In her spare time, Anna plays the trumpet in a funk and soul covers band and is an ultra-endurance open water swimmer. Oh, and it’s pronounced “Por-shy-ski”.
With thanks to the Royal Academy of Engineering for their generous support in making tickets to this event free to London schools.

Your positive outlook on Materials is just infectious!! Thanks for this amazing lecture!!
I don't think we've fully unlocked materials science potential.
Room temperature superconductors!
@@ac.creations element 115..
Thanks for an interesting presentation about materials!
This was a fun and interesting presentation, but I think it would have been better to have more in-depth information about the specific structures and qualities of different materials. Probably should have gotten the craftsmen themselves to come out and demonstrate bits and pieces of their craft for the audience. Nonetheless, still fun and demos are hard to do live too.
Just amazing ❤
awesome presentation!
She just throughly captivated her audience with facts, anedotes an accounts of how material were invented, used an the associated problems, especially with plastics...
I thought we might get deeper in materials unique specifications and what some combinations might give us, or which qualities we get out of them.
These are meant for high school education and below dude
Maybe try her book?
one of my favorite quotes is, "The more you know, the more you know, there's more to know."
Plastic recycling an reuse is a huge industry, an is increasing daily. To make the best use of this fascinating material.
She should write a book.
Love it ❤️
I've missed so much of this because of commercials. It's just abusive now. I'll try to watch again later. Gonna watch the Glass Onion without commercials now.

amazing
I wonder if materials science can explain how a person can be so awesome.
Wow. Thank you heaps for this episode. I greatly enjoyed it and learnt heaps from it. Great displays. 👌👍
When she blew a hole in the CD after heating it.
That was a wow, moment!
I kind of want to try glass blowing but I figured it'd be more about creativity like she did, I use to study art but fell out of it due to it being damn near all computerized and I have no imagination even though I'v got a decent skill in arts, plus some medical issues make it hard to keep my hands steady. xD
I think it should be filled with experiments and demonstrations than history
I heard a rumour that she has a book coming out?
Mark Miodownik's two books on material science are good.
I still find funny “the soviet method of making rubber from potatoes”.
Potato->Ethanol(bad vodka)->Butadiene->Rubber
As regards the history of horns/trumpets, she left out the Shofar (rams horn) used in biblical times, an still used today.
No crumpet trumpet 🤔😋
Years ago, my company recycled 13 million CDs and DVD per month.
I'm a bit dissatisfied with the explanation of why maltodextrin doesn't burn. If that really depends on ring numbers, then polysaccharides like flour/starch shouldn't burn either. But they do. It's more about the degree of fragmentation I think. Or even water molecules that are in the crystalline framework.
But the shoes are really cool!
I don't think it was that malto doesn't burn, it's just that it's harder to burn than sucrose.
Also flours/starches aren't pure polysaccharides, so they might have easier to burn components that help get the reaction started.
@@bryan__m And I just remember that you even need a catalyst for burning sucrose. That whole "burning suggar" thing seems quite interesting for further studying
It's funny that they removed the historical desk for her while they kept it for other people doing fire and explosions, haha..
Yeah, they specifically removed it for her.
They have removed it lots of times.
@@inzombniacc yep, seen lots of videos with it gone. Could even be a different theatre.
Glass melts. It just doesn't have a defined melting temperature.
3:34 An evil genius, Elon Musk type of character... 🤣🤣🤣
I would assume that, coming from a working researcher, the "genius" part is at least somewhat ironic.
I mean, for all that Musk is a complete fraud and an undeniably terrible person, he still puts on the _show_ that's reminiscent of a stereotypical cartoon villain. If you get a bit into linguistics (I recommend Steven Pinker's _The Language Instinct_ for example) you quickly see that there are some "words" that look like multiple words. It's not that Musk is an "evil" "genius" but that he's an "evilgenius". An evilgenius is not a genius who is evil, it's a villain who behaves in a certain way.
To give you another example, think of when you greet someone. "Hey how's it going" isn't actually a sentence, it's just a bit of noise with a specific function in speech: beginning a conversation with someone or acknowledging their presence. Taken separately the components of that phrase would involve asking someone for specifics about their physical/emotional state, but if someone starts to actually _answer_ that not-actually-a-question it feels strange.
Language is full of these little functional words that, on paper, look like sentence fragments or compound words, y'know? (Like that last one!)
'wazzaaaaaaaaaaaahhhh'@@EdwardHowton
All that, an not a script in sight...
Only TWO of the comments below are from humans... 🙄
Very interesting but I feel that I lost third of my time listening of a lot of bla bla family or what ever. But still a good performance and I have learn things so thank you and thanks to RI for showing us that we can learn in a funny way...may be desapointed cause I wanted to learn more.
Have a nice day
Nevermind that the kind of UAP with instantaneous accelerations reportedly use a metamaterial to achieve low energy spacetime warpage. Materials Science will change EVERYTHING we thought we knew, and everything we thought we were already good at doing, like getting around quickly for example.
Hem...
I can't watch a broken snickers lying on the floor
As a queer person in STEM, i cant express how liberating it is to see a butch queer woman actually give a performance and make her talk pop.
Well done Dr Ploszajski!
A bit too much "woke" energy for an upper level institution of such great regard.
um um um ummm *smacks lips* um um um *smacks lips* ... WTF
She is looking like a female version of "Tom Cruise".
So much funny, kiddy blabla.. missing the information in between all the giggly small talk and Side Stories ..maybe better suited for a stand up comedy stage...
Perhaps you commented too early. It was quite interesting and informative.
@@user-wx3ie1eq8nI was wondering how come she was such an engaging speaker
and then she told that she had been doing stand up also
and then on she started to morph into the science side of the topic
And ofcourse in the end it is her book promotion (a science relatable book for dummies I suppose)
Ted Talk nonsense
Yeah science, never gave us anything, right?
Elon Musk is not evil.
Woke lesbian discover that doesn't know anything about what she broke. Ironic. Clownery not lecture
I forgot rich
Rich woke lesbian
IRONIC
After all her discussion about "macho environment" I bet that she is single. Luckily for the man that doesn't have her.
She didn't mean to offend you, so there's no need to get so personal. P.s not all women want a man anyway
