Every year，the Joint Mathematics Meeting brings more than 5，000 math lovers together.It's the largest math meeting in the world.In January 2019，mathematicians flew to the meeting in Baltimore，Md.，to learn about new ideas and talk about their work.Many even came to admire the latest in mathematical art.
   The meeting included an entire art exhibition.Visitors felt amazed at sculptures made from metal，wood and folded paper.One was based on a supersized Rubik's cube.Many like triangles，were arranged in strange and surprising sizes and colors.The collection also included drawings and paintings inspired by the study of numbers，curves（曲线）and patterns.
   Art and math may seem like a strange pairing.People usually experience art through their senses.They see a painting or listen to music.If this art moves them，they will have an emotional response.Working at math
problems is usually viewed as something you think about -not feel.But connections between the two fields reach far back in time.Sculptors and architects in some ancient civilizations included numbers and math ideas into their works.
   "A mathematician，like a painter or a poet，is a maker of patterns，" wrote British mathematician G.H.Hardy in 1940.If a mathematician's patterns are more permanent，he continued， "It is because they are made with ideas. "
   Henry Segerman is a mathematician and artist.When he was in high school，in England，he was good at math and art.But he had to choose. "I went in the math direction back then，" he says.He thought it difficult to succeed as an artist.
   Still，Segerman's math studies led him into the visual areas of math，such as geometry.In 2015，Segerman and some math art friends created a virtual-reality artwork.Participants can put on a pair of VR goggles to float around and through four-dimensional shapes.Art makes it possible to interact（互动）with these shapes，which would be impossible to create in our three-dimensional world.As beautiful as it is to see，Segerman's work also offers a new view on mathematical ideas.
