The title of this video is Tentacles, Kimbo.

to 不定詞

Just because I've wanted to do something that sounds not mathematical but is glass blower Lucas Clark comes over to my house and says, Cliff, I made something and I can't understand it.

Are you trees, eyeglasses or you're treated as two rings linked together like this?

He says to me, This is two rings connecting, I say, Yeah, it's mathematically a to hold tourists, He says.

Okay, they reaches over, is their bag and he pulls out this.

And I said, Yeah, yeah, you've just taken this stretched it And so this is the same.

Is this still a to hold tourists with two holes in it?

It says if you make it out of stretchy rubber.

OK, so he says, What if I I inflate the middle of this?

This, they say, should make no difference in its properties.

It still has 12 holes and connected here.

It would be called to hold tourists or could also be called handle body with two handles on it.

He pulls up the next day, says I can take this handle regal and bring it over there.

And I say, Yeah, that should be no problem.

So the next thing this glass blower doesn't say, what happens if I move this connection here, just carry it around over to there in this connection over here, there's a perfectly legal according to operations in topology, you could move the same.

So he says, I'm going to take that connection in this one.

So he moved those two ears from being next to each other parallel to so that they're connecting like this.

So that becomes that and this one becomes this one here, hopes to have a big nose.

And so this fear part becomes this wide part here, where that new hole come from.

Hey, starts asked me, where is that from?

And then he goes one step further and fully shrinks that into this.

He's telling me that this can be transformed into this following ordinary rules of topology.

It's like me standing with my arms like this.

I am a Kimble, and this is the same as me with my fingers linked together like this.

This space here that my head's waggling around in the same Is this space here, Right here is that space is the same as the space here.

And so I say, somehow this has been transformed to this, which is the total logically the same as going from Ah, Kimbo, two interlinked fingers.

So I'm sitting there and thinking ought to be able to go from here back to this.

The wife nudges me and says, Cut out, Cliff, go to sleep, all right.

And I keep going like this, waggling my fingers around.

It's not working right, and I'm saying, What's wrong with us?

And and and and and a couple days later, visitor comes by three visitors from Denmark.

People are often times coming over my house.

Check out topology and things, and I show this to them.

And these three grad students, I think from Denmark, came through and I showed this to him, and I said, I'll give you a client bottle if you could solve it.

They sit around thinking about it, talking about it.

Couple days later, they show me the answer and I'll show it to you know, I'm going to need a little bit of help.

The way I'll do it is I'll put off put my finger here.

And I claim that going like this is the same top.

This, this tentacle is to just give me a longer finger so I can go like this and round like this over here to my thumb, and then move my thumb along to this.

Thanks to the wonderful miracle of tentacles, I can show that I can go from here to here.

On my left hand, I could do the same thing, but the room with the blue got it with two hands.

So what about what about with two hands going to this?

I'll start with this and I'll start over here and this hand here.
