"Does this only work with the number 3?" "NO!"

But no example shown of the number 5 example, nor what gets 'fiddly' with 7 and up. (Brady's attempt is wrong.)

Things i got from this video: That awesome ring ofc
That silversmithed ring is epic!
Unlike the usual 3-component Borromean rings, The _Borromean Olympic rings_ do *not* have the property that if you make one of the rings disappear, others will fall apart. For that property, you need to look at *Brunnian* links.

Weird. The thumbnail seems correct in that regard. Were there mistaken crossings here?
That's a pretty cool ring, and yes kids still draw that S in textbooks, at least we still did like 5 years ago
We're uploading TWO videos today - the next is on the way!
Gotta love all the great work you're doing in all of your channels mate! Proud to be a subscriber !
1:43 - "For elven kings"
Where can i get one of those rings?
This is by far the best channel I've subscribed to on youtube. I'm always looking forward to the next episode, and I'm not even good at math. It's just intriguing somehow.
well I think you have 400-plus videos to catch up on at periodicvideos! :)
Poor Borimir from LOTR. He only wanted to use Frodo's ring as part of his hobby for making Borromean rings - they are named after him after all. However it all came across the wrong way and it ended up looking like he was trying to steal the ring and then gets himself killed before he has a chance to properly explain himself... :(

I know you’re joking, but IIRC, the name actually comes from an Italian royal family called Borromeo who used the 3-ring version as their crest or some such.
This was very clever and topical. Thank you.
This video is almost 5 years old, but I don't see any comment pointing out that the supposed Olympic Borromean ring is wrong. The basic principle is that the removal of any one ring causes the whole thing to fall apart, but the example here works as long as you keep any 3.
That ring he had was so cool! :O
A borromean wedding ring, the holy trinity. Two people held together by an unbreakable bond called love.

the sound of marker on brown paper gives me tingles down my spine!
Uploaded on my BDay! Thanks numberphile!
I made some Borromean rings out of rubber bands, and realized that's the best way to show them to people. Ask them which two are connected, and regardless of which two they say, just grab them and pull, and they'll separate with a significant gap, but be held together by the third. You can alternate which two you're holding and quickly show someone that no two rubber bands are connected.
WoW! Interlinking rings, who would have thought?
Now I want a ring like that lol :)
Numberphile, Periodicvideos, Deep Sky, Sixty Symbols... it's like chocolate for the brain. Yes, I'll watch another, please Mr Haran.
We want videos more often ! :) They are great
Another great video Brady! Thanx :D
in knot tying, the boromean rings are classified as n bight, a*n lead turks' heads, where a and n are whole numbers. the # of bights is the number of loops around the outside, and the leads are the number of strands in the cylindrical forms' cross-section
You had me at 'Linkages'. :D
LOL @ the end, love you guys
I want my wedding ring to be like the three ringed thingy :D
Yay new video!
You'r the best Brady! :D You have rly gotten the hang of youtube :D I wish you all the best in the future! -Loyal Fan! :)
Dunno if there is one from him, but you can check out MinutePhysics here on youtube - that's the guy he was "beating up" at the end of the video!
The end of that video reminds me of middle school and when everyone was obsessed with drawing s's in a braid style. 3 lines on top, 3 on bottom, 2 in the middle, and then finish with a V underneath and ^ on the top side. Or you could just draw them endlessly on your teachers desk of course. :D
make sure you turn on the annotations (the red speech bubble at the right hand side), it works for me.
Looking at my gigantic 7x7x7 Rubik's Cube (actually it's a V Cube but whatever...) sitting on my nightstand, I keep wondering about the mathmatics of it all. I would love to see a video on this. A 3x3x3 cube would work fine too, but the big one is a lot more facinating. I keep coming up with new ways to make both symmetric and asymmetric patterns. The way everything works together in a VERY spesific pattern, yet still allows me to do basically whatever I want with it keeps blowing my mind.
i really want one of those rings!!
Wow nice fingers...

In addition to numberphile and periodicvideos, Brady also has deepskyvideos, sixtysymbols, nottinghamscience, backstagescience, and several more.
Its such great thing
Now I want a ring[s] like that!
WHAT ! THERE'S A CHEMISTRY CHANNEL !?! I CAN'T BELIEVE I DIDN'T SEE IT BEFORE !
please tell me where i can get a ring like that? thats awesome.
I just found something that boggled my mind quite a bit: Busy Beaver Function. Do you have anything on that?
Brady please get the guys to either change the markers they use or the paper. The scrapping sound goes thru me so much :( im sure im not the only one as well, thanks :D
Doesn't this mean that each ring can't be a circle
@Dagny1978

Yes. At least one of the rings, if not all 3, has to be slightly oval instead of a perfect circle, for it to work.
Hi, im french and I love your videos, could you you put some subtitles for those who aren't good in english? it could help a lot of my friends and my maths teacher!
I made a mobius loop bromian ring.

Any one know where I could buy a ring like that?
I recommend checking out the channel page you have all nottingham university channeles there
I bet the image at 2:27 took ages to create!
If you like this channel, check all of Brady's channels (some may be associated, not his, Im not sure). Periodic Videos, Numberphile, DeepSkyVideo, Sixtysymbols, etc. You can find them linked on his channel. They ALL KICK ASS
you're welcome
Your about to embark on a wonderful journey.
Where could I get a ring like that???
is this like how boromir is the lord of the rings?
What a spanner :D thx
i think this is really cool, but are there any real world uses of a borromean ring?
i want to see how to make that ring!
foodskey, wordsoftheworld, backstage science and bibledex are also some of Mr. Haran's channels. I find them all interesting and educative (:

Poor henry...
really reminds me of a triquetra and valknut
Saw this video, and wanted a ring. Today i bought said ring and was very happy. Then I revisited this video, and found out that my ring(s) isn't a borromean ring :(

I want Borromean wedding rings too. My fiance loves the math part, & I love the symbolism that the rings cannot be separated (& also how unique they are). The jewelers have tried several times now, but they can't seem to make them correctly. They claim the rings won't lie flat, & won't be able to be worn on the finger, if they can make the pattern at all. The only reason they won't say it's impossible is because I showed them this video. If the professor here can make them, surely professional jewelers can.
3:10 "And if you chase this... this blue one..." haha
Oh. I didn't know him by his name :) Thanks
I'm going to try and make a set and see if its possible, just get binder rings or something.
Wow, this is one of those things that makes perfect sense, but I never would have thought of, like toast
Euclidean Knot..! Nice Rythm Algo..!
1:34 I MUST HAVE ONE OF THOSE. MY PRECIOUSSSSSSSSSS...
watch it to the very end, its worth it
gostei e espero um melhor q este...
In the end, the three rings become One ring to rule them all!
Hey, double the fun! *thumbs up*
when I was in middle school I would draw rings like that and on a standard sheet of paper I could link 9-10 rings together on my spare time after I finished my math worksheet. I also figured out how to rig up a deck of playing cards so if I had 2-5 people playing poker I would have the highest hand and win all of the nutty butty bars, that is what we used instead of real money (only cost .25 at the lunch line)
*Insane video journalist.
how can you not have a tv series yet..?!
...and excels at silversmithing. I know plenty of people who can draw very well. I don't know a single person who can smith themselves a nifty ring. I think the professor is quite a remarkable artist too, not just a scientist.
Three rings to rule them all.
yaaay knot theory!
Any idea why they were doing that? Cause I've got none 0_0
I feel sorry for people who closed the video at the outro. They missed a very important and informative part in the history of Numberphile and MinutePhysics! :D
@numberphile -- Food for thought,,, A Borromean 5-ringed Olympic symbol may perhaps better reflect what the Olympics *should* be, but I wonder if the current symbol more accurately reflects the Olympics in reality -- a loose affiliation standing together regarding sportsmanship. A looser affiliation may also symbolize more adaptability, diversity, and less rigidity than five very-tightly-woven Borromean rings. It's not as loose as a mere chain, but more like chain mail.
You can actually make borromean rings with any number of components, not just an odd number. I think the odd number factoid refers to borromean rings made with circles.
Hot damn that ring is cool.
Is the professor related to Lindybeige somehow?
I WANT THAT RING
I want that ring! WTF?! Time for a diy LOL.
If u take a look at this blue one- they're all blue professor!
1:34 I want a ring like that so I can marry two women with it!
As a chainmaille artisan, I call it a cheat...but that's just because the rings don't physically fit right if they are no slightly oval...well done, professor...well done.
Sorry, I meant SixtySymbols. NottinghamScience is where they put their extra videos.
What was Henry doing just laying there like that? :D
What happened to the videos about youtube algorithms?
Brady did you get to see the live broadcast of Curiosity's Landing? There was a reported that was trying so hard to be cool and nice, and I just kept thinking: "Brady could have definitely done a way better job"
Three rings to rule them all...
Did Henry plan to get beat up? He just sort of giggled.
for science, you should check out Sci-Show, if you haven't already
There is, it goes by the name sixty symbols!
Looks like the machine from Contact.
