我们的身体，周围的世界，遥远的星系甚至浩淼的宇宙中，占据99%的物质，到底长什么样？

科学家怎么样去探测10^-15 米尺度内的物质结构？

来听这个报告，你将会得到答案。

More than 99% of the visible matter in the universe is the protons and neutrons. Their internal structure is mostly governed by the strong interaction. Understanding their internal quark-gluon structure is one of the most important subjects in modern physics. Worldwide efforts in the last a few decades have led to numerous discoveries and surprises, but major challenges still remain. An overview of the progress will be presented with a focus on the recent studies of the proton and neutron's electromagnetic and spin structure. Selected highlights of new results from Jefferson Lab will be presented. Plans for future physics programs and major facilities will be discussed.
