The first time I heard about Escher, I was still in the ## show this year, and I was attracted by the dazzling Escher painting that I had to slap on. I never thought that this trip to the Netherlands actually visited the Escher Museum in The Hague, The Hague. Escher, a Dutch painter, the world's most famous visual illusionist. His achievements are unmatched by ordinary people. His paintings really make people feel that "seeing is not necessarily true." It is clear that the stairs to the second floor have returned to the first floor. The birds are suddenly changing into a fish when they are constantly changing. All these impossible sights are in him. The implementation of the pen. The bending of space makes winding possible. Today we know that physical space can be bent by gravity. It can be boundless but it can be finite. Unbounded is not equal to infinity. It seems that Escher's mathematical thoughts are profound and are contained in his paintings! Escher has an incredible magic that conquers people's hearts.
