@PhysInHistory If one wants a simple impossible problem to solve, show a general way to trisect an angle using a compass and straight edge.
Many other problems take advanced math knowledge to understand the problem let alone attempt to solve it.

@DrQz @NobelPrize I believe you’re maybe thinking Kip’s beard is his tongue.

When 2017 physics laureate Kip Thorne collected his Nobel Prize medal, he was overcome with emotion while looking at an image of fellow Nobel Prize laureate, Albert Einstein.
A century ago, Einstein predicted the existence of gravitational waves. These 'ripples' in a four-dimensional spacetime occur when objects with mass accelerate. The effects are very small.
In the 1970s, the LIGO detector was developed, which uses laser technology to measure small changes in length caused by gravitational waves.
Kip Thorne made crucial contributions to the development of the detector, and on 14 September 2015, he was among some 1,000 physicists who were finally able to observe gravitational waves for the first time.
Kip Thorne shared the Nobel Prize in Physics in 2017 with Rainer Weiss and Barry Barish "for decisive contributions to the LIGO detector and the observation of gravitational waves."
