The proton and neutron, known as nucleons, are the fundamental building blocks of all atomic nuclei making up essentially all the visible matter in the universe, including the stars, the planets, and us. The nucleon emerges as a strongly interacting, relativistic bound state of quarks and gluons in Quantum Chromodynamics (QCD), and has a complex internal structure only beginning to be revealed in modern experiments and lattice QCD calculations. Both theory and technology have now reached a point where human is capable of exploring the inner dynamics and structure of nucleons and nuclei at the sub-femtometer distance, which is expected to lead to a new emerging science of nuclear femtography.  In this talk, I will argue that as exciting as the nano-science/technology has been, there must be a quantum transition when we enter the era of femto-science and technology.  The newly proposed Electron-Ion Collider (EIC) will be the much needed tool and the facility to explore the nuclear femtography. With its unique capability to collide polarized electrons with polarized protons and light ions at unprecedented luminosity, and almost all elements of heavy nuclei at high energy, EIC will be the most powerful tomographic scanner able to precisely image quarks and gluons inside the proton and nuclei with a sub-femtometer resolution. EIC is also a precision microscope that allows us to “see” and explore the dynamics binding quarks and gluons together to form hadrons. EIC will address the most compelling unanswered questions about the elementary building blocks of the visible world, and is capable of taking us to the next frontier of the Standard Model of physics.
