- What can physics learn from crochet? How does a simple stitch change the stretch of a scarf, and how are modern materials and manufacturing learning from their wooly ancestors? Join Dr. Matsumoto for a talk about curvature using pattern making, symmetries using quilt squares and flags, hyperbolic space using quilting at crochet, and knot theory and coding using knits.
Speaker:
Dr. Sabetta Matsumoto is an Assistant Professor in the School of Physics at the Georgia Institute of Technology. She is passionate about using textiles, 3D printing, and virtual reality to teach geometry and topology to the public.

As a knitter (and one-time engineer and applied mathematician), I found this completely riveting. Thanks.
I think of knitting and describe it to non-knitters as binary code, 1s and 0s = knit and purl. With the seemingly infinite combination of the two you can create so many wonderful things!
I used that to add my then-bf's name in binary to a sweater I used to propose to him. He's a programmer. And he's now my husband...
Thank you for raising the profile of knitting! I've been knitting for over 50 years and I think some people see it as silly and a bit old fashioned. But I've always found the manipulation of shapes, infinite patterns and the combinations of stitches absolutely fascinating.
It's funny to me, because knits are everywhere, people just don't think about it. It reminds me of how I used to think machines sewed clothes together, and I learned later that humans actually have to do all of the sewing, because machines can't do that automatically. Knitting and sewing helped me appreciate how much thought and experience goes into such everyday items as clothing. An expertly made piece is amazing!
I am at 9 minutes in so far. Stockinette stitch is created by knitting on one row and purling on the next row. Garter stitch is created by knitting every row. I have always been fascinated by this idea and look forward to watching the rest after dinner!
If you're working in the flat, yes, because you turn the work and work alternatively on the front side and on the posterior side. But if you're working in the round, stockinette is all knit stitches, reverse stockinette is all purl stitches and garter is alternating rows of knits and purls!
I need to watch this again and try to dream about it, I feel like this is bringing me to the edge of some great epiphany...
As a knitter and a data scientist/statistician (my degree was in physics and computer science) this was fascinating! I really love Escher’s work - I will have to give sewing a go and make the hyperbolic blanket! Thanks for a brilliant talk and showing that textiles is mathematical.
This presentation was amazing. I'm new to knitting but this answered so many questions you don't get in how-tos.
I'm a new knitter, I have always loved different, different from this, and different from that. Texture and colors that complement each other, combinations that make a muted or bold statement. I also hated math, but knitting, crocheting, and sewing all incorporate some kind of mathematical skills that I didn't even realize that I was practicing. I love this video, I'm almost at the top of my existance here on this plane, but anything goes as long as you are consistent in the application of your design/format.
I remember, as a very young child, I tried to make a dress by tracing an outline of myself, making two copies and sewing them together. I was completely surprised when it didn't fit. My little brain couldn't see where all the extra fabric went. 😅
What a cool thing to have done as a child!
the flash back this comment gave me.... i did the exact same thing!
This explains so much, but leaves me with so many more questions. I think it is fair to say that it was inspiring, if not then at very least it was intriguing.
Best knitting video ever!
this is the best video i have ever seen thank you for making it
I don't know if Dr Matsumoto reads the comments here, but the petals of the Lily are curved for similar reasons that a leaf would be, since flower petals are modifications of a leaf, repurposed for sexual reproduction (form-fitting and attracting pollinators). Most leaves, when growing into maturity from their adolescent stages, unfurl from their bud. To the best of my understanding, it's just an efficient way to take up space while forming. :)
Note, I'm not a proper scientist with letters to my name, just a nerdy nerdy person who's endlessly curious
Can someone explain me in a scientific way, what’s happening on the stockinette stich that tends to curl?
From my understanding, stockinette stitch uses less yarn (than knit), thus “pulling”), making it curl.
You can see a visual of this by observing ribbing (sets of 1K1P, or 2K2P etc), and where the K goes into the P, there is more of a gap in the fabric. (Hence, K uses MORE yarn than P).
You can do a trick to avoid/help this by knitting into the back of the stitch. Also, the “style” of knitting can affect this… whether you are a continental (aka “picker”), or an English (aka “thrower”).
These styles affect the placement of the stitch (front and back “leg” of the stitch is opposite in either styles.
All very interesting isn’t it !?!?
Have you looked into crochet in this way too? I know we can make 3D objects a little easier than knitting.
Now do a a video on the physics of crochet. Or would that be called chaos theory😂?
Isn’t that “new stitch” just a KFB that’s purled together on the next row?
I'm confused about the garter stitch graphic. Garter stitch doesn't have any purls and is super stretchy but one row of purl then one row of knit is stocking stitch. I love your work.
Yes I noticed the error too knitters know garter is knitting every row and Stockinette is knit one row and purl the other.
@@thestitchcafe8295 I hesitated to correct the Dr. but I am hopeful it is appreciated
Garter in the round has purls every other row
I believe the confusion is that the pictures labels the “v” shape as K and the purl bump as P independent of what stitch made that shape. When you knit a stitch, the front forms a “v” and the back forms the purl bump. Conversely when you make a purl stitch the front forms the bump and the back forms the “v”. Say you knit across the first row of a project then turn your work and purl across the second. If you look at the right side of the fabric you will see only the knitted “v”s so both rows would be designated as K stitches even though you purled the second row. And if you look at the wrong side you will see both rows with the purl bump so they would be designated with all Ps even though you knitted the first row.
@@thestitchcafe8295 @judithjunop Structure-wise, althought not always working-wise, garter is knit one row, purl one row, where as stockinette is structure-wise all knits and reverse stockinette is all purls. Dr. Matsumoto didn't go into the detail which -wise they were talking about, but structure-wise the schematics were right.
Ok fine, I’ll finally learn how to make my iPhone pay mono-recorded audio in stereo… in order to watch a video on the physics of knitting?!
Hong Kong is 72 degrees rotation, yes?
I thought saw too because 5 x 70 makes 350 degrees so there are 10 missing...
Knitting is more elastic than weaving and crocheting.
That’s why I don’t crochet - it’s making a stiff fabric from a drapey/stretchy yarn. It just seems “wrong” to me! Like it doesn’t honor the yarn.
@@barbaraseville4139it depends on what you’re making. Crochet is better for home decor (e.g blankets, coasters, baskets, pillows, etc.) But like you said, it’s all up to personal preference.
It is nice to know how to use all of them! Each has its place in textile creation don't they?
@@Woodlawn22 yes, nailbinding is interesting too. And weaving
@@barbaraseville4139I knit and crochet, and you can absolutely create drape in crochet. It very much depends on the pattern and the yarn used. I have crocheted a shawl/wrap that called for lace weight yarn, and it is a lacey pattern, and has beautiful drape. I’ve made the same piece using fingering weight yarn, and it still has great drape, but IMO not as much as when I used the lace weight yarn. If you search for lace patterns, using either lace or fingering weight yarn in crochet in Ravelry, you will find many that have that beautiful drape 😊🧶
Vocal fry
As a mathematician and knitter, I wanted to watch this. But, that's why I had to stop after a few minutes. That grinding quality that younger women have started using in their voices is like nails on a chalkboard, to me. And it wreaks of self importance. I'm sure the video was great. I'm sorry.
It is annoying. I tried to do it but I'm 63. Too old.😊
Yes! I find several videos that I can't watch due to the off-putting vocal fry. Someone needs to get the word out that many people are NOT watching content because of vocal fry.

ITT: people who expect women to always be bubbly. You're going to stop yourself from learning something because you don't like how someone talks.
Well I thought this was interesting but then it just got to dry and didn't dive into knitting like I thought it would.
