If one remembers this particular episode from the popular sitcom ‘Friends’ where Ross is trying to carry a sofa to his apartment, it seems that moving a sofa up the stairs is ridiculously hard.

But life shouldn’t be that hard now should it?

The mathematician Leo Moser posed in 1966 the following curious mathematical problem: what
is the shape of largest area in the plane that can be moved around a
right-angled corner in a two-dimensional hallway of width 1?
This question became known as the moving sofa problem, and is still unsolved fifty years after it was first asked.


The most common shape to move around a tight right angled corner is a square.

And another common shape that would satisfy this criterion is a semi-circle.


what is the largest area that can be moved around?

Well, it has been
conjectured that the shape with the largest area that one can move around a corner is known as “Gerver’s
sofa”. And it looks like so:


Wait.. Hang on a second

sofa would only be effective for right handed turns. One can clearly
see that if we have to turn left somewhere we would be kind of in a tough

Prof.Romik from the University of California, Davis has
proposed this shape popularly know as Romik’s ambidextrous sofa that
solves this problem.


Although Prof.Romik’s sofa may/may not be the not the optimal solution, it is definitely is a breakthrough since this can pave the way for more complex ideas in mathematical analysis and more importantly sofa design.


Have a good one!

OH also someone in one of my group chats mentioned a math joke and i remembered two of my favorite jokes of all time so

the “b” in “benoit b. mandelbrot” stands for “benoit b. mandelbrot”


the simplest anagram you can make from banach tarski is “banach tarski banach tarski”

I laughed at this a lot.
