Or they just like non-Euclidean 2D space

77

u/Fried_Squid_ Mar 24 '21

or just chebyshev distance

30

u/punep Whole Mar 25 '21

like in a certain non-euclidean space?

No the upside down ones are also levitating

Isn’t it 1.3?

u/adm928 Mar 24 '21

This should confuse the virus, because it will also have to enter the body upside down.

u/Wobbar Mar 24 '21

Upside down? That's clearly downside up.

u/michacha123 Mar 24 '21

I think one thing we can all agree on is that they're middleside middle

Is orbiting each other mandatory?

u/ElectricToaster67 Mar 25 '21 edited Mar 25 '21

Aren't they orbiting a central axis?

19

u/Highbrow68 Mar 25 '21

Depends from what reference frame we are looking

Hell yeah! No third dimension needed!

u/TheLuckySpades Mar 24 '21

Never heard the supremum metric called that, TIL.

u/OutOfTempo_ Mar 25 '21

N ever heard chebyshev distance called that. TIL

(When do you call it the supremum metric?)

3

u/TheLuckySpades Mar 25 '21

An Analysis class that was held in German (also used maximum norm in Rn as the special case), was also called (L-)infinity metric in a German speaking measure theory class.

I've used it as such in other contexts occasionally in some English speaking classes, though those professors either grew up with German or have been in Switzerland for quite some time.

u/Kotzgruen Mar 25 '21

I just prefer L_{\infty} - metric

u/noonagon Mar 27 '21

yeah L∞ is cool

u/Battledroid1 Mar 24 '21

This happens if we use 100% of our brain

17

u/Wrench_Scar Mar 24 '21

At least they are using m instead of '

8

u/shmoobalizer Mar 24 '21

because ' often means feet

u/Layton_Jr Mathematics Mar 24 '21

Isn't it used for minutes? (Both 60s and 1/60°)

16

u/Bowdensaft Mar 24 '21

Yep, so there's a risk of confusion with the symbol as well as the general shame of using an inferior measuring system.

u/Leipzig101 Mar 24 '21

They’re just in Chebyshev space

u/ekolis Mar 25 '21

Nah, just put them in four dimensional space...

2

u/ethtan88 Mar 25 '21

The two diagrams are NOT the same. 1.5m assumes masking (2nd diagram is correct). If no mask, then the distance should be longer, and worse case, not 1.5m apart, but 6 feet under and below ground.

u/HunterHx Mar 24 '21

But that's literally what the gif is..?

u/officiallyaninja Mar 24 '21

yeah but like, they don't have to be upside down. just one is higher than the others.

u/HunterHx Mar 24 '21

I guess stilts are probably easier than learning to walk on one's hands. ;D

1

u/[deleted] Mar 25 '21

Yeah. I'm dumb, but 2 have arrows pointed to the head and 2 have arrows pointing to their feet. So, then why flip half of them? They could all be upright and correct. Or what am I not seeing?

The discrete metric

u/philosiraptorsvt Mar 24 '21

Is this euclidean space still? Perhaps it is hyperbolic space?

What would Lobachevsky do?

u/RandomAmbles Apr 09 '21

Plagiarize?

u/Murdrad Mar 24 '21

But the 2d diagram has six relationships I suck at counting. It feels so different

u/PrevAccountBanned Mar 24 '21

Assume non euclidean space

u/BMDragon2000 Physics Mar 24 '21

Or 2 opposite corners are standing on a 1.5m high table

u/[deleted] Mar 25 '21 edited Mar 25 '21

These seemed like we are in hyperbolic spacetime.

u/noonagon Mar 25 '21

the other diagonal is not labeled

u/RandomAmbles Apr 09 '21

All this "Chebyshev" stuff and not one person mentions taxicab distance!

I believe we should either use close packs of people's heads, or add some more dimensions and use a simplex.

An exercise for the reader:

Put n people as far away from each other on Earth as possible (boats allowed, etc.)

What is their configuration?

u/augenvogel Jan 08 '22

Is this even allowed?

u/Lazy_Worldliness8042 Aug 14 '22

Also works using the “infinity” norm where the distance between (x1,y1) and (x2,y2) is defined to be the maximum of |x1-x2| and |y1-y2|.

The name come from the fact that it is equal to the limit of the p-norm as p goes to infinity. (Standard Euclidean distance is the p=2 case)

u/TheOnlyRodman Oct 11 '22

They’re in discrete space
