"Is that one of the weirdest things that ever happened on Numberphile?" - "It's in the top 10."
The other 9 places are all taken by Cliff Stoll.
I think there's some Tadashi Tokieda in there, too.
Chris Stoll has 23 videos with number files.
There's no way this in the top 10. PS. More Chris Stoll please!
Talking about knots, in Royal Society, featuring Chemistry, making puns, and having fun... This is one of the most Brady videos out there!
why do you dilute the quality of your channel with this rubbish
More Ayliean! She's awesome :)
"Mathematicians need friends" is a nice saying
3:16 Brady needs to do a top 10 weirdest things that have happened on Numberphile.
More Ayliean please! It's always great to watch someone who is so totally into what she's talking about! :)
with a scarf you can connect your hands for the trefoil knot
To make a knot with one not a friend
Give them a hug and by the end
You'll have yourself a life-long knot friend.
3:42 I smell a T-shirt right here XD
The enantiomer of thalidomide that causes birth defects is also the one that is used to treat multiple myeloma and AL amyloidosis - basically it has an anti-angiogenic property. (It also works as an immunomodulator)
Thinking about other knotty Numberphile videos - if Ayliean had Cliff Stoll's 'Tentacles Akimbo' extensions and Sylvain Cappell's Noo Yawk way of saying 'Reidemeister moves' she'd be sorted.
(Actually scrap that, 'Reidemeister moves' sounds just as lovely in Scottish.)
3:33 it may be not a knot, but I think it might be a Mobius loop :)
putting the movie Morbius on loop? don't mind if i do...
@@anatine_banana_69 It's morbin time!
Getting 'Tentacles Akimbo (with Cliff Stoll)' vibes from the attempted self hugs!
Agreed, Ayliean needs Cliff's tentacles in order to conduct these solo experiments. (That sounds wrong but you know what I mean.)
All of the different fields are hugging each other!
3:15 So, what is the weirdest thing someone has done on numberphile?
All I can think of offhand is the various "print out a large thing", or some of the games from the cool Japanese professor. Sure I'm forgetting something really random tho
@@petemagnuson7357 Actually, I think that Cliff Stoll, the klein bottle guy may be responsible for some of the strangest things on the channel. His level of passion and eccentricity, while very fun and entertaining, are also a bit odd at times.
@@phiefer3 Yeah, I'd definitely put conical scone up on the list.
@@U014B Yep, IMO it could be divided into two categories, weird things done with your body, and at all. Mr. Stoll would probably take two spots overall... having a robot to fetch klein bottles hidden under the floor would be high too.
Probably something Cliff Stoll did. "Is it okay if I point with my nose" is probably one of the weirdest thing I can think of.
A good dose of enjoyment and zeal for those science students who feal the weight of studying more than the fun of it. Numberfile people are so infectious! I love it.
I love how she persuades everyone into being a mathematician. That's the same thing I teach all my music students: Everyone understands music, in his/her own level, be it a musicologist or "just" listener. I think that applies for all fields in life.
I need a new video with Ayliean every week. She´s so lovely and passionate about math.
3:37 Unfortuknotly
2:25 Cliff: let me introduce my tentacles
Not sure that Thalidomide really belongs in a video with a "look at me hugging myself" tangent....
Hahaha... hopefully that's not the only reason why mathematicians need friends. BTW, this looks like what Conway and Gardner would also enjoy.
When crossing your hands if you then grab a piece of string at either end with both hands. You can then uncross your hand without letting go and itll form an overhand knot! Kind of a way to do it alone.
Yes! This! Interdisciplinary synthesis is the future.
The extra stuff at the end was great, I think it would've been a perfect discussion to end off the first video as well!
Good work Brady
The problem with thalidomide is that it interconverts between the enantiomers within the body.
Watching her eyebrows is quite fun
Thanks for this extra on knots.
I'd learned about chirality in medicine reading about differences in effectiveness of the two, specifically with ketamine.
Knot Knot Knoting on heavens door
I learn something new today… thank you!
We still use thalidomide and related drugs in medicine- It's used for certain cancer treatments but no longer as an antiemetic since we have better safer drugs now.
What this needed was for a flustered Keith to barge in at the end shouting "WHAT DO YOU THINK YOU'RE DOING, THIS IS THE ROYAL SOCIETY HAVE SOME DECORUM". Everyone falls silent. Camera zooms into a Keith closeup. He turns to camera and says "KNOT acceptable Brady". End.
4:50 Heisnberg from Bb
she is shining!:)
When the extra is longer than the main video
Improved my knowledge of hugs. I'll try to do linked hugs with my loved ones😍
We're all your friends 😊
Hold a piece of string with your hands (thus connecting them) if you don't want to need friends..
You can cross your feet, ant wrap your hands around one leg, to make a knot, no friends needed :(
I really like her shiny Make-up
That was fun. :)
It is not true that two knots having the same invariant/s implies they are the same knot. What is true is that if two knots disagree on an invariant then they are necessarily different, but if two knots agree on an invariant/s (e.g. 3-colorability) then they are not necessarily the same. (a set of invariants where this converse is also true is known as a 'complete set of invariants')
Is it true that in Topology, there is no complete set of invariants known among all possible Topological spaces?
@@MrAlRats Yes that's right. There is not even a complete set of invariants for smooth manifolds (which are a well-behaved class of manifolds, which are themselves a well-behaved class of topological spaces). For smooth manifolds of dimension ≤ 3 there are complete sets of invariants (e.g. the classification of 2-manifolds, i.e. surfaces, is very simple; just the genus and whether or not the surface is orientable are a complete set of invariants), but for smooth manifolds of dimension ≥ 4 there is no complete set of invariants (it has been proven that no computable set of invariants can exist).
Ayliean reminds me of Frost from The Flash.
2:30 If you could do that, you would be in the ER.
Does she actually have a straight angle tattoeed around her elbow when holding arm in straight angle? Brilliant. So simple but so clever.
Also yes, more of her. I need weird and creative math applications.
But are YOU a knot maths person?
Could you cheat and use your legs? Could be quite the challenge for all the contortionist tuning in!!
(s)
thought the same.. use legs too,... nude,... and make video
I wouldn't call that cheating at all! Using one's legs is perfectly valid, but still difficult, and requires some serious flexibility.
Was going to comment that I did it with my hands and legs.
@@arunabhganodwale1022 Post a pic or a vid.
What about tangles? If you work with tangles you don't need friends.
I'll be her friend 😁
Is there a name for the trefoil knot variation at 1:30? It feels like it should have a name. Also, which is the left-handed (vs. right-handed) trefoil knot?
I'm a big hugger/mathematician
Kind of awkward on „private“
