So if you're on a festival with a lot of mathematicians, go for the first toilet and you'll be the first one to use it.

[Milkymalk]

So the moral is: Don't be a mathematician's first ever date.

[metapod]

And in the end, I learned that dating is essentially the same as choosing between nasty toilets.

[krotenschemel]

This leads to two arkward situations: while dating:"So you really want to date me?" - "Yeah I need reference values" and while married "Honey back then, in your womanizing days, why did you choose me amongst all these women?" - "Because you were the next best after I dated 37% of them"

If you were at a concert full of mathematicians the first 37% of toilets would be the cleanest cause no one would of used them

She's got some amazing handwriting o___o

Today I learned that you can choose a spouse the same way you choose a toilet.

-xln(x) is also a famous problem in Physics. The entropy according to Boltzman can be written as S=-k*p*ln(p) (K:= Bolzman-Constant). Very nice video by the way!

Wait, I have to date 0, 37*8billion people before I can start to choose?

[sudarshankj]

Terrific explanation. Things like these must be included in the curriculum to make Math more relatable, practical and fun!

[Fiyaaaahh]

This only covers how to find the single best one. It is not fine-tuned to optimize the average outcome (although I can imagine that a 37% best-case scenario helps the average a lot). What method do I use to get the best average outcome? And how does this generalize if I would be willing to settle for a top-2 toilet/partner ? Or top x%, for lim x -> 0.

As a math student i really love how you're explaining so clearly !
You're an amazing teacher ! :D
Thanks for the awesome content !

[Dengakuman]

When your geiger conter starts buzzing that's definitely not a good toilet!

[thesemoves]

Haha... I'm loving the "prof j grime" scribble on one of the toilet walls!

[martinmessner]

I love how the first toilette you visit at a music festival is a LSD trip... :D

[SheezyBites]

If you tel everyone this everyone's going to leave the first K toilets so they're going to be the most hygenic...

[pawccefawce]

I shat myself after 12 minutes of watching.

[CastorQuinn]

I'd love to see how this maths changes if you want to try to select *one of the best two* toilets, or any toilet that's in the top ten percent of toilets.  You'd no longer be looking at a point on the curve but a range.

[iClone]

I gotta get a date first for this mathematical model to work..

[fullerdb]

I hope everybody learns this and uses this, because I'll then always pick one from the first 37% that nobody is using. ¦¬Þ
