### what did the painter do wrong?

this was painted by a quite famous (<< Munch) painter in Norway   in the 1950's, what did he do wrong? (parts of the walls of the cafe of the physics institute university of oslo)

Can you take another picture a little bit more to the left?  The bar is occluding the bit between 1/2 and sqrt(pi).

The continued fraction is wrong, in many ways! I bet it should be an infinite fraction or else the answer can never be rational number. If it was infinite then the answer would be "1+golden ration" .. so maybe change the first 2 into a 1?

Cool painting though! Munch be worth many millions?

It is a painted Bar! I would likely be fined millions to remove it. Painted layers, equations behind?

" Munch be worth many millions?"

so what is your Bid? yes it is expensive as it would involve taking down the wall. Or you just want to buy it and leave it where it is?

The $\sqrt 7$ identity is wrong. The continued fraction should be the golden ratio with the only radical being $\sqrt 5$. So the two side cannot be equal.

so he messed up that also?
well supposedly he forgot the ln in front of 2, so they had to add "ln" above the 2 later on, can be seen from the painting kind off. And now u say one more error, I need to tell them and ask if they can fix it. this is what happen when one hire painters/artists with no math skills?

or a math-smart painter putting in math errors on purpose? wanting people to think...?

It must be an experiment on the students.

What was the painter trying to accomplish by introducing a deliberate error in a place full of scientists and which would put them in jail if they ever thought about correcting it?

I thought the $\ln$ was a Picassorian touch, what with scrambling the conventional relative position of objects...

Now here is a question. What would be the least amount of paint (with or without erasing what is already there) to correct the mistake, and still maintain the original stylistic aesthetics of the painting?

Exactly!

$\sqrt 5 = 1 + 2*$ then the continued fraction

You are only a few lines of sklearn away from removing the bar yourself !

Indeed, you can fill in the blanks with a nested Generative model. First a layer that generates math statements conditioned on the surrounding text , and a second one that paints them like Munch.

Generative models have come really far in the last couple of years, just look at this Ramen-GAN! Hmmm!
